The present document studies the means to identify calls with spoofed Calling Line Identification terminating in the CS domain where the call could have originated from either inside or outside the CS domain. Calling Line Identification (CLI or CLID), also called Caller Identification (CID), evaluates and transmits a caller's number while Calling Line Identity Presentation (CLIP) enables displaying the caller's number during call setup or ringing. Usual applications for CLIP are:
to display the original number of the caller;
to display a caller's presentation number, e.g. a doctor calling a patient out of hours who doesn't want to disclose his private number but showing instead the number of his office;
to display a number unrelated to the calling line, e.g. call centers displaying numbers related to their customers (depending on national regulations).
But CLI can also be misused to display a misleading number in the display that is in no way related to the originator of the call. This behaviour is called CLI spoofing or spoofed call. CLI spoofing ranges from harmless hoax to criminal activities like for example Voice Phishing (vishing) by displaying the forged number of a bank in order to steal the callee's credentials. And although CLI may be unreliable, people use it to decide whether to accept a call or not.
This study item studies the detection of a spoofed call as the first step, and prevention as a second step if detection is achievable. In particular, the goals of this document are:
• Outline valid threat scenarios for spoofed calls coming to 2G and 3G CS domains;
• Analyze and evaluate if any tools in 3GPP can be used to counteract spoofed call detection and prevention;
• Study and identify any other suitable techniques or mechanisms for spoofed call detection and prevention.
NOTE: When the "potential requirements" and "potential solutions" from the present document might be introduced into normative documents (Technical Specifications - TSs), the word "should" needs to be changed into "shall" (with bold characters).

The present document studies security features and mechanisms for protection against false Base Stations broadcasting false Warning Notifications.
The default terminal behaviour is to accept all Warning Notifications even if their authenticity is unknown (i.e. no security protection). The default terminal behaviour is therefore open to the presentation of false Warning Notifications issued by false BSs even in countries without a Public Warning System (PWS) deployed.
Examples of false BS risks include, but are not limited to:
• False Warning Notifications to induce panic;
• Abuse of warning system broadcast channel to send advertising / spam.
These security features and mechanisms are optional since there are regions and countries that do not require this functionality.

The present document studies the security aspects of the Group Communication Service Enabler for LTE (GCSE_LTE) and gives an evaluation of possible technical security solutions supporting such an Enabler. The present document looks at security from system perspective and defines functional security requirements for all entities.
Stage 1 requirements for these services are defined in 3GPP TS 22.468 [2].
Different possible Stage 2 solutions for GCSE have been studied in 3GPP TR 23.768 [3].
3GPP TS 23.468 [8] provides the stage 2 description for the 3GPP system provided enablers to support GC services using E-UTRAN in Rel-12.
Based on the work done in 3GPP TS 22.468 [2], 3GPP TR 23.768 [3], and 3GPP TS 23.468 [8] the objectives of the present document are to identify the threats and deduce security requirements, develop GCSE_LTE security solutions, and determine which solution(s) from the present document (Study/TR phase) should be converted into normative specifications for Rel-12.
NOTE: The present document collects requirements that are not normative.

The present document describes the test procedure for the radiated performances measurements of the 3G/2G user equipment/mobile stations (UE/MS) in active mode in both the uplink and the downlink. The FDD UE test procedure is based on the test method developed as a result of COST 273 Sub-Working Group (SWG) 2.2 members’ contributions. Background work has also been made in the former COST259 project. The TDD UE test procedure is based on the test method developed as a result of CCSA TC9 WG1 members’ contributions. Background work has been made in the former CCSA TC9 project.
The measurement procedure explained in this document applies to UE/MS used under the “speech mode” conditions that correspond to predefined positions for voice application when the handset is held close to the user’s head. This method is also applicable to free space measurements for UE/MS devices. The data transfer position (free space) explained in this document applies when the UE is used away from the user’s head. For LME and LEE devices free space configuration without head and hand phantoms is applicable. Free space measurements are applicable to devices used in the data transfer position that consist of the laptop mounted equipment (LME) plug-in UEs and laptop embedded equipment (LEE) UEs.
The tests apply to UEs and laptops using single or multiple receive antennas. For GSM technology this is applicable to all MSs and for 3G technology this is applicable to “one antenna” UEs and “RxDiversity” UEs.
The testing methodology applies to any single or multi-mode (GSM / UMTS / TD-SCDMA) terminals.
The radio tests considered here are:
1. The measurement of the Total Radiated Power (TRP)
2. The measurement of the Total Radiated Sensitivity (TRS)
The test procedure described in this document measures the performance of the transmitter and the receiver, including the antenna and also the effects of the user.
The major parts of this test procedure are based on the 3-D pattern measurement method. It has been considered necessary to define some items and components in the test procedure in detail, such as test channels and phantom set-ups, in order to make the testing in different laboratories harmonized. The procedure is, however, not limited to some specific antenna chambers or positioners.

The objective of this study [20] is to evaluate the use of measurements for positioning, which are currently specified for UE and eNodeB for other purposes but are not currently included in LPP and LPPa, for an RF pattern matching positioning technology in LTE.
The RFPM performance with these measurements will be compared to the RFPM performance based on the measurements currently specified for the E-CID location method.
The implementation could be an E-SMLC based eNodeB-assisted location service using existing E-UTRAN measurements which are provided to the E-SMLC via the LPPa positioning protocol and UE-assisted location service using existing UE measurements (RSRP, RSRQ and UE Rx-Tx time difference only) which are provided to the E-SMLC via LPP positioning protocol.
The present document is intended to complement already 3GPP standardized location methods and existing 3GPP location work items.

The present document contains the result of the Device to Device (D2D) study item.
The Feasibility Study on Proximity-based Services (FS_ProSe, TR 22.803 [2]) has identified services that could be provided by the 3GPP system based on UEs being in proximity to each other. The identified areas include services related to commercial services and Public Safety that would be of interest to operators and users.
The objectives of this feasibility study are to evaluate LTE Device to Device proximity services, as follows:
Within network coverage
Outside network coverage
Discovery
Non public safety &
public safety requirements
Public safety only
Direct Communication
At least public safety requirements
Public safety only
In particular:
1. Define an evaluation methodology and channel models for LTE device to device proximity services, including scenarios to compare different technical options to realize proximal device discovery and communication, appropriate performance metrics, and performance targets (e.g. range, throughput, number of UEs supported). [RAN1]
2. Identify physical layer options and enhancements to incorporate in LTE the ability for devices within network coverage: [RAN1]:
- to discover each other in proximity directly in a power-efficient manner.
- to communicate directly, including enhancements to LTE interference management and scheduling that allow the LTE network to enable, manage, and continuously control all direct, over the air, device to device communications.
3. Identify and evaluate options, solutions and enhancements to the LTE RAN protocols within network coverage [RAN2 primary, RAN3 secondary]:
- to enable proximal device discovery among devices under continuous network management and control,
- to enable direct communication connection establishment between devices under continuous network management and control,
- to allow service continuity to/from the macro network
4. Consider terminal and spectrum specific aspects, e.g. battery impact and requirements deriving from direct device to device discovery and communication [RAN4].
5. Evaluate, for non public safety use cases, the gains obtained by LTE device to device direct discovery with respect to existing device to device mechanisms (e.g. WiFi Direct, Bluetooth), and existing location techniques for proximal device discovery (e.g. in terms of power consumption, and signaling overhead) [RAN1, RAN2].
6. The possible impacts on existing operator services (e.g. voice calls) and operator resources should be investigated [RAN1].
7. For the purposes of addressing public safety requirements, identify and study the additional enhancements and control mechanisms required to realize discovery and communication outside network coverage [RAN1, RAN2].
The identified options/enhancements should reuse the features of LTE as much as possible.
The study will cover:
- Single and multi-operator scenarios, including the spectrum sharing case where a carrier is shared by multiple operators (subject to regional regulation and operator policy)
- LTE FDD and LTE TDD operations
In this study item, the study of direct communication shall address at least public safety requirements and use cases..
It is assumed that aspects related to service authorization, system level architecture, security, and lawful interception are covered in the 3GPP TSG SA Working Groups.

Previously the deployment of the 3GPP LTE technology in the bands 2305 to 2315 MHz and 2350 to 2360 MHz (known as the Wireless Communications Service band, or ‘WCS' in the United States), could not be accommodated due to technical and operational constraints present in FCC regulations. This is commonly known as Block A (2305 - 2315/2350 - 2355 MHz) and Block B (2310 - 2315/2355 - 2360 MHz) in the WCS Band. The FCC on October 17, 201 amended and confirmed the technical and operational characteristics for WCS which enable the deployment of LTE FDD technology in Blocks A & B in the frequency band covering 2305 - 2315 MHz and 2350 - 2360 MHz.

The objectives of this Study Items are:
● Identify the partial traffic loading levels and other realistic system level parameters (e.g. traffic and interference models including interference level, time offset between cells and frequency offset between cells) and performance metrics for studying the feasibility of CRS IM in a synchronized homogenous network assuming:
- 3GPP Case 1 as a starting point
- non-colliding CRS between serving and dominant aggressor/interfering cells and
- non-colliding CRS between dominant aggressor/interfering cells
- The homogeneous deployment and relevant system parameters should reuse as much as possible those defined in the Rel-11 performance study of MMSE-IRC
● Identify the baseline receiver which can be used for evaluating the gain of CRS IM in a synchronized homogenous network considering:
- Reuse of CRS IM receiver assumed for Release 11 FeICIC.
- Reuse of MMSE-IRC receiver as the baseline receiver. MMSE-IRC does not differentiate CRS or data interference when suppressing them and was assumed for Release 11 work item on interference rejection combining.
● Agree on interference levels, interference models and simulation parameters for link level evaluations.
● Evaluate the system level and link level gains of CRS IM with respect to the baseline MMSE-IRC receiver in a synchronized homogenous network deployment under the various loading levels identified.
- Gains of CRS IM from 1 and 2 aggressor cells CRS shall be evaluated and compared.
- Modeling of realistic CRS IM receiver for system level performance evaluation should be clarified and agreed if possible
● Investigate UE complexity tradeoffs e.g. tradeoff between number of interferers to cancel and the number of transmit antenna ports.
● The introduction of CRS IM based receiver requirements for homogenous deployments will only use the existing Release 11 signaling of CRS assistance information.
Note 1: Interference from neighboring cells’ PDSCH is not the focus of this study item. Any interference from data, which varies according to the traffic loading level, is assumed to be suppressed in the same way as in Rel-11 with the baseline MMSE-IRC receivers.
Note 2: Non-colliding CRS is prioritized and will be studied first while colliding CRS is not precluded. But the study will focus only on UE demodulation aspects.

As LTE deployments evolve, operators would like to reduce the cost of overall network maintenance by minimising the number of RATs. Machine-Type Communications (MTC) is a market that is likely to continue expanding in the future. Many MTC UE's are targeting low-end (low average revenue per user, low data rate) applications that can be handled adequately by GSM/GPRS. Owing to the low-cost of these devices and good coverage of GSM/GPRS, there is very little motivation for MTC UE suppliers to use modules supporting the LTE radio interface. As more and more MTC UE's are deployed in the field, this naturally increases the reliance on GSM/GPRS networks. This will cost operators not only in terms of maintaining multiple RATs, but it will also prevent operators from reaping the maximum benefit out of their spectrum (given the non-optimal spectrum efficiency of GSM/GPRS). Given the likely high number of MTC UE's, the overall resource they will need for service provision may be correspondingly significant, and inefficiently assigned.
Therefore, it is necessary to find a solution to ensure that there is a clear business benefit to MTC UE vendors and operators for migrating low-end MTC UE's from GSM/GPRS to LTE networks.

- assigned by multiple network operators, where an individual Public User Identity is served by only a single network operator for all IMS services;
- provisioned by network operators in the case where other URI schemes have already been, or are going to be, provisioned by different service providers in the internet.
The Public User Identities could be SIP URIs associated with or derived from user identities of services from the Internet domain.
This study also aims to clarify the relationships (e.g., business, interworking) between the Domain Name Owner, the assignee of sip:user@domain where it is not the same as the domain owner, and operators sharing the domain name.
Any potential regulatory aspects will also be considered.

The scope of the technical report is to capture the results of a study into the feasibility of enhancing IMS network architecture. This report intends to study the feasibility of enhancing IMS network architecture as follows,
- Investigating architectural improvements to reduce the complexity of signalling procedures by reducing the signalling hops, or the number of options and combinations (by looking at different groupings of combining existing entities);
- Investigating means to improve system-level load balancing and reliability;
- Investigating possibilities for reducing configuration workload to save OPEX.
- Investigating the introduction of IMS Overload Control mechanisms.
Backward compatibility with current IMS specifications shall be ensured.
NOTE: overlap with SA5 and CT4 work need to be monitored.
This report is intended to explore potential architecture improvements and also provide conclusions on the above aspects with respect to potential future normative specification work.
There are a number of functions involved in call session setup in IMS network. Interfaces and interactions between network elements may be a little complicated and not that efficient. It is deemed beneficial to review the current IMS architecture including aspects such as the possible optimization of interfaces/reference points (by looking at different groupings of combining existing entities), reducing options of solutions for the same issues, relevancy of certain functions etc.
IMS network service availability largely relies on the reliability of network entities. If some network elements implementing critical functions (e.g. S-CSCF, HSS) fail, service availability may be impacted. Moreover network elements may not be fully utilized because network load may not be well distributed, e.g. some nodes may be overloaded due to sudden traffic increase, while others may be under loaded to some extent. Though there are some element level approaches to solve these problems, some system level solutions should be studied, for example, the method to distribute load between network elements in different geographical locations especially when a disaster happens, such as earthquake.
Network expansion may require significant manual configurations, and the network maintenance and upgrade may be time-consuming and also may be costly for operators. Introducing self-organization features may improve the network intelligence and reduce the efforts of manual configuration.
The objectives of the study for investigating the introduction of IMS Overload Control mechanisms are to:
- Determine the parts of IMS architecture for which overload control mechanisms are needed;
- Evaluate the applicability of candidate solutions for Overload Control to the SIP entities of the IP multimedia core network architecture, including:
- mechanisms having already been specified or studied within 3GPP and their possible enhancements,
- mechanisms specified or studied by other bodies (e.g. ETSI TISPAN, IETF) and their possible enhancements,
- other mechanisms, if proposed within this work item;
- Provide recommendations based on analysis.

The objective is to study an evolved policy solution through enhancement of 3GPP policy framework. One of the aims of the study is to ensure a policy architecture that provides an extensible framework for easy reuse with new IP based services by identifying areas where improvement of specifications are feasible. The study item will look into solutions for the examples in the section above.
Existing components for consideration in the Policy Study are functions and interfaces to/from
- PCRF, PCEF and BBERF;
- SPR, HSS;
- ANDSF;
- IMS policy decision making entities.
The study aims to provide a more comprehensive way (e.g. going beyond existing 3GPP PCC framework) to handle operator policies for all IP / service flows (IMS and non-IMS) in a coordinated manner and under varying network conditions while keeping in view aspects such as:
- user preferences;
- user subscriptions;
- service requirements;
- terminal capabilities (including converged terminals);
- network capabilities (3GPP and those non 3GPP accesses inter- working with 3GPP);
- Session transfer and terminating policies;
- Security policy control, e.g. firewalling and gating.
Roaming scenarios are considered as part of this study. Compatibility with existing system architecture elements are protected and backward compatibility is expected. All types of policies i.e. static/pre-provisioned, dynamic, network based, UE based are considered in the study.
When a key issue is resolved sufficiently to be incorporated into the specification in an independent manner, the study work may move forward for a decision for normative specification work on such issue(s) using a new work item or a TEI.

The present document investigates architecture solutions for making the Network Provided Location Information (NPLI) related to the access network that the UE is camped on available to the IMS nodes whenever the IMS operator needs to record this information either to fulfil legal obligations, for charging or for other purposes.
This study will gather the various existing regulatory and operator requirements that the solution needs to fulfil, in particular:
- whether the provision of the Network Provided Location (NPLI) Information and local time are applicable to all the users served by a network (i.e. "non-roaming" subscribers and inbound roamers) or only to the network operator subscribers;
- whether Network Provided Location (NPLI) and local time need to be made available also if EPS/GPRS and IMS services of a subscriber are provided by different networks;
- what events trigger the need to retrieve the Network Provided Location (NPLI) and local time.
The study is then expected to produce solution candidates which detail the necessary Stage 2 message flows, architecture enhancements and new functionality needed in the EPS and GPRS networks. The solution candidates will also describe what IP Multimedia Subsystem elements are affected in order to obtain the Network Provided Location (NPLI).
The solutions produced will then be assessed against the criteria identified in section 7 where recommendations for normative work will also be made.

In the context of support of roaming for voice over IMS, the GSM Association has decided that local breakout in the visited network will be needed (see GSMA PRD IR.65 [6]). This is because local breakout can be regarded as one cornerstone to allow the replication of the charging principles on which CS roaming is based on. However there are several other aspects that need to be considered e.g. the split/bundling of user and control plane, capturing of SDP information needed to generate charging records, to make such principles applicable to voice over IMS roaming.
This study item will therefore investigate solutions for the provision of voice over IMS in roaming scenarios that facilitate the realization of a charging model that replicates the principles of CS model.
It will be studied whether changes to the core 3GPP specifications are needed and if so which ones. The study will focus on IMS layer and not EPC aspects.
As some of the aspects of the roaming are outside the scope of 3GPP (e.g. decision to anchor media or control plane, interaction with carrier networks, roaming agreements) this study will be performed in close cooperation with the GSM Association which may provide additional requirements and guidance during its development.

MPS will enable National Security/Emergency Preparedness (NS/EP) users (herein called Service Users) to make priority calls/sessions using the public networks. This service needs to be ensured also under special conditions such as network congestion. Service Users are the government-authorized personnel, emergency management officials and/or other authorized users. Effective disaster response and management rely on the Service User's ability to communicate during congestion conditions. Service Users are expected to receive priority treatment, in support of mission critical multimedia communications.
The enhancements for MPS evaluated in this document are priority aspects of EPS packet bearer services and priority related interworking between IMS and EPS packet bearer services. These enhancements enable the network to support end-to-end priority treatment for MPS call/session origination/termination, including the Non Access Stratum (NAS) and Access Stratum (AS) signalling establishment procedures at originating/terminating network side as well as resource allocation in the core and radio networks for bearers. Priority treatment will be applicable to IMS based multimedia services, priority EPS bearer services and CS Fallback.
This document clarifies the architectural requirements for MPS, considers the priority service scenarios, and evaluates solution alternatives. Solutions will be proposed and evaluated based on the following three service categories: IMS based multimedia service (voice, video etc), priority EPS bearer services (PS data without IMS interaction) and CS Fallback. Common issues for multiple service categories should be resolved by single solution to limit the amount of overall functionality and to avoid complexity.
The basic eMPS, i.e. priority handling of IMS based multimedia service, EPS bearer services and CS Fallback have completed in Rel‑10. In Rel‑11, Single Radio Voice Call Continuity (SRVCC) from LTE to UTRAN/GERAN/1xCS will be investigated based on Rel‑10 SRVCC specification.
The result of the analysis should be suitable as a basis for normative MPS specification work.
The scope of the MPS part is to further investigate:
- The signalling and procedures for identifying priority and authorizing the usage of priority service.
- The required priority attributes used in enabling end-to-end priority marking and priority treatment during establishment, modification and release of an IMS based priority voice/video/data session.
- The scenarios and capabilities for supporting priority EPS bearer data services.
- The potential impacts on existing and relevant standard procedures in order to provide preferential treatment for MPS requests in the event of congestion.
- Inter-working with other IMS and CS networks to provide an end-to-end priority service.

This Technical Report studies and evaluates architectural aspects of the System Improvements for Machine Type Communications requirements specified in TS 22.368 [2].
Specifically, the following system improvements are considered:
- Architectural enhancements to support a large number of Machine-Type Communication (MTC) devices in the network;
- Architectural enhancements to fulfil MTC service requirements;
- Support combinations of architectural enhancements for MTC, though not all combinations may by possible.
The end-to-end aspects of communication between MTC devices and MTC servers (which can be located outside or inside the network operator's domain) are out of the scope of this study. However, the transport services for MTC as provided by the 3GPP system and the related optimizations are considered in this study. In addition, the aspects needed to ensure that MTC devices and/or MTC servers and/or MTC applications do not cause peak loads of short duration (e.g. a "busy minute" rather than a "busy hour") are within the scope of this TR.
Even though some provided solutions may be beneficial for communications from a MTC Device towards another MTC Device, this particular type communication has not been explicitly considered in this Technical Report.
This Technical Report analyzes architectural aspects to achieve these objectives and to gather technical content until it can be included in the relevant technical specifications.
NOTE: Some aspects in this feasibility study have led into normative specification in TS 23.682 [20], TS 23.060 [21], TS 23.401 [5], TS 23.221 [22] and TS 23.272 [23]. The text of the present document was not updated to align with normative specifications.

The present document contains the result of the study on the impacts on signalling between the UE and core network when energy saving measures are applied to network entities.
The study aims, within the defined CT1 work areas, at:
- analysing UE idle mode procedures and signalling between the UE and core network resulting from switch on/off of radio equipment in all types of 3GPP accesses, including home cell deployment and I-WLAN, as well as power adaptation of radio equipment (where applicable);
- performing a corresponding analysis for connected mode UEs;
- analysing similar impacts from activation status of non-3GPP access networks;
- documenting limitations, weaknesses and inefficiencies in these procedures, with emphasis on mass effects in the signalling between the UE and core network; and
- studying potential optimizations and enhancements to these procedures.
The study also evaluates potential enhancements to 3GPP specifications under CT1 responsibility.
This study takes into account decisions made by other 3GPP working groups in their related work.

The present document establishes Over the Air antenna minimum requirements for User Equipment (UE) and Mobile Station (MS).
Requirements are defined for roaming bands for the speech position (beside the head) and for the data transfer position (free space). Requirements for free space are applicable to devices used in the data transfer position and consist of laptop mounted equipment (LME) plug-in UEs and laptop embedded equipment (LEE) UEs. All bands are potential roaming bands, and the requirements for roaming bands shall therefore be fulfilled for all bands supported by a UE/MS.
Requirements for operating bands are dependent on how the network has been built and are thus operator specific and can not be specified here. Recommended performance values for operating bands (Annex B) are however included in this specification for information. It should be recognised that the ability to meet the recommended performance values depends on the number of frequency bands supported by the UE/MS.

The present document is intended to capture RAN1 and RAN4 findings produced in the context of the study item "Uplink Transmit Diversity for HSPA" [2]. The study is focussed on schemes that do not require any newly standardised dynamic feedback signalling between network and UE. The uplink transmit diversity schemes maybe categorized into two types of algorithms:
- transmission from 1 Tx antenna (e.g. switched antenna Tx diversity); or
- simultaneous transmission from 2 Tx antennas (e.g. transmit beamforming).
The scope is understood to be limited to schemes which also do not require any semi-static mode configuration signalling for demodulation. The possibility of semi-static disabling of a transmit diversity scheme is not precluded.
The work under this study item aims at:
- evaluating the potential benefits of the indicated UL Tx diversity techniques;
- investigating the impacts on the UE implementation;
- investigating how to ensure that the UE operating an uplink Tx diversity will not cause any detrimental effects to overall system performance;
- investigating the impacts of Tx diversity on existing BS and UE RF and demodulation performance requirements; and
- analyzing how to derive any additional performance/test requirements that are deemed needed as an outcome of the study, as well as understanding the impacts of any such new requirements.
The performance of closed loop transmit diversity, in which the Node-B controls and dynamically adapts the pre-coding vector that a UE shall apply is described in [124].

HSPA based mobile internet offerings are becoming very popular and data usage is increasing rapidly. Consequently, HSPA has begun to be deployed on more than one transmit antenna or more than one carrier. As an example, the single cell downlink MIMO (MIMO-Physical layer) feature was introduced in Release 7. This feature allowed a NodeB to transmit two transport blocks to a single UE from the same cell on a pair of transmit antennas thus improving data rates at high geometries and providing a beamforming advantage to the UE in low geometry conditions. Subsequently, in Release-8 and Release-9, the dual cell HSDPA (DC-HSDPA) and dual band DC-HSDPA features were introduced. Both these features allow the NodeB to serve one or more users by simultaneous operation of HSDPA on two different carrier frequencies in two geographically overlapping cells, thus improving the user experience across the entire cell coverage area. In Release 10 these concepts were extended so that simultaneous transmissions to a single UE could occur from four cells (4C-HSDPA).
When a UE falls into the softer or soft handover coverage region of two cells on the same carrier frequency, it would be beneficial for the non-serving cell to be able to schedule packets to this UE and thereby improving this particular user’s experience, especially when the non-serving cell is partially loaded. MultiPoint HSDPA allows two cells to transmit packets to the same UE, providing improved user experience and system load balancing. MultiPoint HSDPA can operate on one or two frequencies.
