6.1.11 RIMS and RIFP
The generation of Ka through algorithm B2 involves the use of two random values RIMS and RIFP. RIMS is sent from CTS-FP to CTS-MS and RIFP is sent from CTS-MS to CTS-FP. Both RIMS and RIFP are 64 bits long.

1 Introduction
The purpose of this annex is to describe the short message teleservice. Three different types of short messages are defined, namely short message MT/PP (Mobile Terminated/Point-to-point), short message MO/PP (Mobile Originated/Point-to-point) and Cell Broadcast short messages.

2 Definition of the short message service MT/PP and MO/PP
For both mobile originated and mobile terminated services the Service Centre acts as store and forward centre. The Service Centre is functionally separate from the PLMN although this does not preclude an integrated implementation. More than one service centre may be connected to a PLMN. Messages may be input to the ser...

2.3 Standard tones
MS generated tones will be generally in accordance with CEPT (GSM 900 and DCS 1800), or ANSI T1.607 (PCS 1900 for NA) recommendations, where appropriate, and are listed in table 1. Any network originated tones will be according to PLMN or PSTN choice.

2.7 Signalling information element confidentiality
A procedure should be implemented providing for the confidentiality of signalling information elements on the radio path. In Technical Specification GSM 02.09 the signalling information elements which need to be protected are given. The Encryption Key is calculated in both the MS and the network. Detailed information i...

2.8.2 Packet handling functions in GGSN
The GGSN should act as a gateway that provides interface(s) to other packet data networks. The GGSN should further perform the functions of routing packets in both directions between these networks and one or more SGSN’s. The GGSN should also download (from SGSN) and store subscriber parameters required for handling th...

3.1.1 Definitions
Location registration means that the PLMNs keep track of where MSs are located in the system area. The location information is stored in functional units called location registers. Functionally there are four types of location registers: - the home location register (HLR) where the current location and all subscriber p...

3.1.2 Procedures
Procedures related to location registration are specified in Technical Specification GSM 03.12. They comprise: i) location updating which enables the MS to inform the network that its location area has to be updated, i.e. the MS has received a location area identity which is different from that contained in its memory...
