e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3 Parameters
| |
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.1 Message-Identifier
| This parameter identifies source/type of a CBS message and is passed transparently from the CBC to the MS/UE. Its format is defined in clause 9.4.1.2.2.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.2 Old-Serial-Number
| This parameter equates to the parameter - Serial Number sent between the BSC/RNC and the MS/UE. Its format is defined in clause 9.4.1.2.1.
This parameter enables a particular existing CBS message, from the source/type indicated by the message identifier, to be identified.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.3 New-Serial-Number
| This parameter equates to the parameter - Serial Number sent between the BSC/RNC and the MS/UE. Its format is defined in clause 9.4.1.2.1.
This parameter enables CBS message change to be indicated since it is altered every time the CBS message is changed. The serial number identifies a particular CBS message, which may be several pages in length, from the source indicated by the message identifier.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.4 Number-of-Pages
| This parameter enables the number of pages in the CBS message to be indicated.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.5 Cell-List
| The cell-list identifies a sequence of one or more cells to which the primitives apply.
The following applies for GSM only:
The cells in the list are described in 3GPP TS 48.008 [13] and can be identified by the CBC or BSC in LAC and CI format or CI format only.
In addition (see 3GPP TS 48.008 [13]) it is possible for the CBC to refer to all cells in a LAC or in a complete BSC. If supplied, the Cell-List parameter must refer to at least one cell.
The following applies for UMTS only:
a) For CBS the cells are refered to as Service Areas. As described in 3GPP TS 25.401 [17] a Service Area Identifier (SAI) is used to uniquely identify an area consisting of one or more cells belonging to the same Location Area. Such an area is called a Service Area and can be used for indicating the location of a UE to the CN.
b) The Service Area Code (SAC) together with the PLMN-Id and the LAC will constitute the Service Area Identifier.
- SAI = PLMN-Id + LAC + SAC.
c) The SAC is defined by the operator, and set in the RNC via O&M.
NOTE: For CBS, a Service Area shall consist of only one Cell. The mapping of SAI onto cell is controlled by the RNC and managed by an O&M function.Given the above differences between cell identification in the two directions, a cell list sent from the CBC to the BSC/RNC has a different structure compared to a cell list sent from the BSC/RNC to the CBC. The different cell lists are described in clauses 9.3.5.1 and 9.3.5.2.
The following applies for E-UTRAN only:
- The cells in the list are described in 3GPP TS 36.413 [34].
The following applies for NG-RAN only:
- The cells in the list are described in 3GPP TS 38.413 [40].
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.5.1 Cell-List sent from CBC to BSC/RNC
| The CBC to BSC/RNC Cell-List contains a length parameter identifying the number of cell-identifications present in the list, a Cell-Id-Discriminator, which is common for all cell-identifications in the list, and a sequence of cell‑identifications.

e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.6 Channel Indicator
| The following applies for GSM only:
This parameter indicates the CB channel, which shall be used for broadcasting the data:
- basic channel;
- extended channel (supporting such a channel by the network or MSs is optional);
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.7 Category
| This indicates the priority of the message:
- High Priority: to be broadcast at the earliest opportunity.
- Background: to be broadcast when no CBS messages of category "High Priority" or "Normal" are broadcast. The repetition period defines the minimum broadcast requirement.
- Normal: to be broadcast according to the associated repetition period.
If the category is omitted, the default category implied is "Normal" message.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.8 Repetition-Period
| This indicates the period of time after which broadcast of the CBS message should be repeated. The minimum period with which a CBS message consisting of one page may be broadcast over the air interface is a period of 1.883 s in GERAN. The minimum period with which a CBS message may be broadcast over the air interface in UTRAN is a period of 1 s.
The value of "Repetition-Period" shall be in the range 1 to 4095 for GERAN and in the range of 1 to 4096 for UTRAN, where each unit will represent the value of one minimum period.
NOTE: In previous versions of the present specification the the maximum Repetition-Period was defined to be 1024.
In the event of a conflict where the BSS/RNS has more than one CBS message to send at the same time, the BSC/RNC shall decide the order of such CBS messages as an implementation matter.
NOTE: The time period 1.883 s approximately reflects one 8 x 51 multiframe sequence of the GSM radio interface. The higher capacity of the RNC enables the CBC to send more than one CBS message consisting of one page with the minimum repetition rate to a Node B.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.9 No-of-Broadcasts-Requested
| This specifies the number of times the CBS message is to be broadcast.
The parameter may take any value up to 65535 (this maximum allows the CBS message to be broadcast approximately every 1.883 s for more than 24 h). If the parameter is set to 0 then the CBS message will be broadcast indefinitely (i.e. until the BSC receives an appropriate Kill-Message Request/Indication primitive).
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.10 No-of-Broadcasts-Completed-List
| This parameter is a list indicating the number of times that the CBS message (i.e. all pages of the CBS message) has been sent to each cell in the Cell-List for broadcast over the air interface.
The cells in the list are described as per clause 9.3.11.

This information element is related to the particular referenced cell in the list and contains the number of times a CBS message (i.e. all pages of a CBS message) has been sent to this cell for broadcast. The No-of-Broadcasts-completed information element represents the number of full broadcasts made of a CBS message, and that the CBS message is being (or had been) broadcast.
The optional No-of-Broadcasts-Compl-Info information element may be supplied to indicate to the CBC one of the following cases:
- overflow;
the count of the number of full broadcasts made of a CBS message has overflowed, and that the CBS message is being (or had been) broadcast. The actual number of broadcasts completed is greater than the value indicated in the No-of-Broadcasts-completed information element;
- unknown;
indicates that there is no information regarding the number of broadcasts completed in the BSC/RNC for the CBS message with the old serial number. The value indicated in the No-of-Broadcasts-completed information element is undefined in this case.
The No-of-Broadcasts-Completed-List must contain at least one cell.

The following values should be coded:
- no DRX;
- length of the schedule period.
If a schedule period length greater than 40 is used, the schedule message cannot be built entirely if more than 40 CBS messages have to be described in the period. Therefore, schedule period length shall be reduced to 40.

|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.3.19 CBS-Message-Information-Page n
| This parameter is of a fixed length of 82 octets and carries up to and including 82 octets of user information. Where the user information is less than 82 octets, the remaining octets must be filled with padding (see 3GPP TS 23.038 [3]).
The content of a CBS-Message-Information-Page is passed transparently from the CBC to the MS/UE.
In GSM the CBS-Message-Information-Page n becomes the 'Content of Message' parameter at the MS.
In UMTS and E-UTRAN, the CBS-Message-Information-Pages together with the associated CBS-Message-Information-Length parameter are broadcasted as a single unit over the radio inteface, and are part of 'CB Data' parameter at the UE.
In the case where the user information is GSM 7 bit default alphabet encoded, the appropriate padding characters and bit-fill are added to the end of the user information to complete the CBC-Message-Information-Page (see 3GPP TS 23.038 [3]).
In the case where the user information is 8 bit encoded, the appropriate padding octets are added to the end of the user information to complete the CBC-Message-Information-Page (see 3GPP TS 23.038 [3]).

e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.1 GSM
| The CBS messages which are transmitted by the BTS for the MS include the CBS Message (information for the user) and Schedule Message (schedule of CBS messages).
The use and the formatting of the CBS messages, which contain information for the MS user, is described in this clause.
The Schedule Message is broadcast to support CBS DRX mode for Mobile Stations. The Schedule Message is helpful in minimizing battery usage for Cell Broadcast in the Mobile Station, because it allows the MS to ignore transmissions of CBS messages the customer is not interested in. The use and formatting of the Schedule Message is described in 3GPP TS 44.012 [7].
The handling of the GSM only applicable ETWS Primary Notification messages differ from what is stated in this clause and is instead described in clause 9.4.1.3.

The most significant bit of the update number is octet 2 bit 3. The most significant bit of the Message Code is octet 1 bit 5 and the least significant bit of the Message Code is octet 2 bit 4. The most significant bit of the Geographical Scope is octet 1 bit 7.
Message Code:
The Message Code differentiates between CBS messages from the same source and type (i.e. with the same Message Identifier). Message Codes are for allocation by PLMN or SNPN operators.
The Message Code identifies different message themes. For example, let the value for the Message Identifier be "Automotive Association" (= source), "Traffic Reports" (= type). Then "Crash on A1 J5" could be one value for the message code, "Cow on A32 J4" could be another, and "Slow vehicle on M3 J3" yet another.
In the case of transmitting CBS messages for ETWS, i.e. the Message Identifier has a value for ETWS (see clause 9.4.1.2.2), a part of Message Code can be used to command mobile terminals to activate emergency user alert and message popup in order to alert the users. Message Code format for this purpose is as follows:
5

Emergency User Alert
Popup
NOTE 1: The exact behaviour of the UE is specified in 3GPP TS 22.268 [28]. Whether the UE setting is overridden is subject to regulatory requirements.
NOTE 2: Emergency user alert includes alerting tone and other user alerting means such as vibration, according to the UE's capability. The types of alert (e.g. the kind of tone, vibration, etc) are implementation dependent and may be subject to regulatory requirements.
NOTE 3: The popup indication shall take precedence over the setting of the DCS Message class (see 3GPP TS 23.038 [3]), and the Geographical Scope with regard to Display Mode 'immediate'.
The codings of the Emergency User Alert and Popup fields are shown below:
Field
Code
Instruction to Terminal
Emergency User Alert
0
No instruction as to emergency user alert.
1
Activate emergency user alert.
Popup
0
No instruction as to popup.
1
Activate popup on the display.
Geographical Scope:
The Geographical Scope (GS) indicates the geographical area over which the Message Code is unique, and the display mode. The CBS message is not necessarily broadcast by all cells within the geographical area. When two CBS messages are received with identical Serial Numbers/Message Identifiers in two different cells, the Geographical Scope may be used to determine if the CBS messages are indeed identical.
In particular, the Geographical Scope tells the mobile if the CBS message is:
- only cell wide (which means that if a message is displayed it is desirable that the message is removed from the screen when the UE selects the next cell and if any CBS message is received in the next cell it is to be regarded as "new"), or
- PLMN/SNPN wide (which means that the Message Code and/or Update Number must change in the next cell, of the PLMN or SNPN, for the CBS message to be "new". The CBS message is only relevant to the PLMN or SNPN in which it is broadcast, so any change of PLMN (including a change to another PLMN which is an ePLMN) or SNPN means the CBS message is "new"), or
- Location Area wide (in GSM) (which means that a CBS message with the same Message Code and Update Number may or may not be "new" in the next cell according to whether the next cell is in the same Location Area as the current cell), or
- Service Area wide (in UMTS) (which means that a CBS message with the same Message Code and Update Number may or may not be "new" in the next cell according to whether the next cell is in the same Service Area as the current cell), or
NOTE 4: According to 3GPP TS 23.003 [2] a Service Area consists of one cell only.
- Tracking Area wide (in E-UTRAN) (which means that a warning message with the same Message Code and Update Number may but need not be "new" in the next cell according to whether the next cell is in the same Tracking Area as the current cell), or
- Tracking Area wide (in NG-RAN) (which means that a warning message with the same Message Code and Update Number may but need not be "new" in the next cell according to whether the next cell is in the same Tracking Area as the current cell).
The display mode indicates whether the CBS message is supposed to be on the display all the time ("immediate") or only when the user wants to see it ("normal"). In either case, the CBS message will be displayed only if its Message Identifier is contained within the "search list" of the mobile (see clause 9.3.2). These display modes are indicative of intended use, without indicating a mandatory requirement or constraining the detailed implementation by mobile manufacturers. The user may be able to select activation of these different modes.
The coding of the Geographical Scope field is shown below:
GS Code
Display Mode
Geographical Scope
00
Immediate
Cell wide
01
Normal
PLMN/SNPN wide
10
Normal
Location Area wide in GSM,
Service Area wide in UMTS, Tracking Area wide in E-UTRAN, Tracking Area wide in NG-RAN
11
Normal
Cell wide
Immediate = default direct display.
Normal = default display under user interaction.
Code 00 is intended for use by the network operators for base station IDs but this code can also be used for other applications. Use of GS=00 takes precedence over the setting of the DCS Message class (see 3GPP TS 23.038 [3])
Update Number:
The Update Number indicates a change of the message content of the same CBS message, i.e. the CBS message with the same Message Identifier, Geographical Scope, and Message Code.
In other words, the Update Number will differentiate between older and newer versions of the same CBS message, within the indicated geographical area. A new CBS message may have Update Number 0000; however this number will increment by 1 for each update.

e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.1.2.2 Message Identifier
| This parameter identifies the source and type of the CBS message. For example, "Automotive Association" (= source), "Traffic Reports" (= type) could correspond to one value. A number of CBS messages may originate from the same source and/or be of the same type. These will be distinguished by the Serial Number. The Message Identifier is coded in binary.
The ME shall attempt to receive the CBS messages whose Message Identifiers are in the "search list". This "search list" shall contain the Message Identifiers stored in the EFCBMI, EFCBMID and EFCBMIR files on the SIM (see 3GPP TS 11.11) and any Message Identifiers stored in the ME in a "list of CBS messages to be received". If the ME has restricted capabilities with respect to the number of Message Identifiers it can search for, the Message Identifiers stored in the SIM shall take priority over any stored in the ME.
The use/application of the Message Identifier is shown in the following table, with octet 3 of the Message Identifier in hex shown first, followed by octet 4. Thus "1234" (hex) represents octet 3 = 0001 0010 and octet 4 = 0011 0100.
In a PLMN, the MS shall discard a CBS message in Message Identifier value range "A000hex-AFFFhex" unless it is received from:
- HPLMN;
- EHPLMN; or
- PLMN that is equivalent to either HPLMN or EHPLMN.
In an SNPN, the MS shall discard a CBS message in Message Identifier value range "A000hex-AFFFhex" unless it is received from the subscribed SNPN or an SNPN equivalent to the subscribed SNPN.
Networks shall only use Message Identifiers from the range 4352 – 6399 (1100 hex – 18FF hex) for Public Warning System as defined in 3GPP TS 22.268 [28]. If a message Identifier from this range is in the "search list", the ME shall attempt to receive this CBS message. Processing of different language codes is specified in clause 9.4.1.2.3 and clause 9.4.2.2.4.

e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.1.2.3 Data Coding Scheme
| This parameter indicates the intended handling of the CBS message at the MS, the alphabet/coding, and the language (when applicable). This is defined in 3GPP TS 23.038 [3].
When the SIM indicates one or more language preferences, the ME shall, by default, use the language(s) stored in the SIM (in the EFPL file) to set any language filter mechanisms provided by the ME.
Optionally, when allowed by language code processing specified below, the user can select the language(s) required by using an MMI, to determine whether a particular CBS message should be displayed.
Where the message relates to a public warning system, the Message Identifier values 4370 through 4382, 4396 and 4398 relate to warning messages delivered in languages which are mandatory to receive. The ME shall not use any language filter mechanisms or use the language(s) selected through the MMI to determine whether a particular CBS message should be displayed for these Message Identifier values. This does not affect the ability to set a particular message identifier by MMI.
Where the message relates to a public warning system, the Message Identifier values 4383 through 4395, 4397 and 4399 relate to warning messages delivered in languages which are optional to receive. For these values, the ME can use language filter mechanisms and the MS may use the language(s) selected through the MMI to determine whether a particular CBS message should be displayed. Even if the Message Identifier is not settable by MMI, the message shall still be discarded if the language is not set to be displayed.

e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.1.2.4 Page Parameter
| This parameter is coded as two 4-bit fields. The first field (bits 0‑3) indicates the binary value of the total number of pages in the CBS message and the second field (bits 4‑7) indicates binary the page number within that sequence. The coding starts at 0001, with 0000 reserved. If a mobile receives the code 0000 in either the first field or the second field then it shall treat the CBS message exactly the same as a CBS message with page parameter 0001 0001 (i.e. a single page message).

|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.2.2.1 Message Type
| This parameter indicates the type of a message, either a CBS message or a Schedule Message. The Coding of the Message Type is described in 3GPP TS 25.324 [19].
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.2.2.2 Message ID
| This parameter identifies the source and type of the CBS Message (see also 3GPP TS 25.324 [19]). It is identical with the Message Identifier described in clause 9.4.1.2.2 with respect to its structure and possible value range. Within a multi technology network of one operator, e.g. GSM combined with UMTS, the values identifying a given topic shall be identical for both the Message ID and the Message Identifier described in clause 9.4.1.2.2.
The UE shall attempt to receive the CBS messages whose Message ID's are in the "search list". This "search list" shall contain the Message IDs stored in the EFCBMI, EFCBMID and EFCBMIR files on the USIM (see 3GPP TS 31.102 [18]) and any Message Identifiers stored in the UE in a "list of CBS messages to be received". If the UE has restricted capabilities with respect to the number of Message ID's it can search for, the IDs stored in the USIM shall take priority over any stored in the UE.
The MS shall discard a CBS message in Message Identifier value range "A000hex-AFFFhex" unless it is received from:
- HPLMN;
- EHPLMN; or
- PLMN that is equivalent to either HPLMN or EHPLMN.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.2.2.3 Serial Number
| This parameter identifies a particular CBS Message from the source and type indicated by the Message ID (see also 3GPP TS 25.324 [19]). It is identical with the Serial Number described in clause 9.4.1.2.1 with respect to its structure and possible value range.
|
e2219d60c1c9a192756e2fe7890303a5 | 23.041 | 9.4.2.2.4 Data Coding Scheme
| This parameter identifies the the alphabet/coding and the language applied to a CBS Message as defined in 3GPP TS 23.038 [3].
When the USIM indicates one or more language preferences, the UE shall, by default, use the language(s) stored in the USIM (in the EFPL file) to set any language filter mechanisms provided by the UE.
Optionally, when allowed by language code processing specified below, the user can select the language(s) required by using an MMI, to determine whether a particular CBS message should be displayed.
Where the message relates to a public warning system, the Message Identifier values 4370 through 4382, 4396 and 4398, relate to warning messages delivered in languages which are mandatory to receive. The ME shall not use any language filter mechanisms or use the language(s) selected through the MMI to determine whether a particular CBS message should be displayed for these Message Identifier values. This does not affect the ability to set a particular message identifier by MMI.
Where the message relates to a public warning system, the Message Identifier values 4383 through 4395, 4397 and 4399, relate to warning messages delivered in languages which are optional to receive. For these values, the ME can use language filter mechanisms and the MS/UE may use the language(s) selected through the MMI to determine whether a particular CBS message should be displayed. Even if the Message Identifier is not settable by MMI, the message shall still be discarded if the language is filtered or is not set to be displayed.
