14、ns Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS defines the stage 2 of the Voice Broadcast Service (VBS) within the digital cellular telecommunications system (Phase

15、2/Phase 2+). GTS are produced by TC-SMG to enable the GSM Phase 2+ specifications to become publicly available, prior to submission for the formal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specif

16、ications for all Manufacturers, Network operators and implementors of the Global System for Mobile communications. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be repu

17、blished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specification; x the second digit is incremented for all other types of changes, .e

18、. technical enhancements, corrections, updates, etc. Reference is made within this GTS to GSM-TSs (note). NOTE: TC-SMG has produced documents which give the technical specifications for the implementation of the digital cellular telecommunications system. Historically, these documents have been iden

19、tified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase l), or ETWETSI Technical Reports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancements of the digital cellu

20、lar telecommunications system. These version 5.x.x GSM Technical Specifications may be referred to as GTSs.

27、.0: January 1996 3 Definitions and abbreviations 3.1 Definitions Definitions used in this specification are also defined in GSM 02.69. broadcast channel: Downlink to be allocated in each cell of the service area for a particular broadcast call. All mobile stations of the destination subscriber being

28、 service subscribers in one cell shall listen to the common downlink. group members: Service subscribers entitled to belong to a particular group classified by a certain group identification (group ID). broadcast call member: Any group member or dispatcher participating in an on going broadcast call

29、. broadcast call attributes: Service area, dispatcher identities and acknowledgement destinations applying to a broadcast call. Group Call Register (GCR): A functionality in the network containing the broadcast call attributes. The attributes are assigned by registration. group call anchor MSC: The

30、MSC responsible for managing and maintaining a particular broadcast call. The group call anchor MSC is determined as the one controlling the cells of the service area. For broadcast call services where the service area exceeds an MSC area, the group call anchor MSC is predefined in the network. grou

31、p call relay MSC: MSC controlling cells of a service area which are not under control of the group call anchor MSC for those broadcast call services where the service area exceeds one MSC area. notification: Notifications are given on common channels or dedicated channels in order to inform group me

32、mbers which are either in idle mode or in dedicated mode or participating in a group call or broadcast call on the existence of broadcast calls. Notification Channel (NCH): Common channel on which the notifications are sent by the network (equivalent to a paging channel). 3.2 Abbreviations Abbreviat

33、ions used in this specification are also listed in GSM O1 .O4 l. For the purpose of this specification, the following abbreviations apply: eMLPP GCR: NCH: VBS: VGCS: enhanced Multi-Level Precedence and Pre-emption Group Call Register Notification Channel Voice Broadcast Service Voice Group Call Serv

34、ice Page 9 GSM 03.69 Version 5.0.0: January 1996 4 Main concepts 4.1 Group definition Service subscribers can become group members on a PLMN wide basis to one or more groups pre- defined in the network by a corresponding group identification (group ID). The membership enables them to receive broadca

35、st calls associated with that group ID. In addition, certain group members are entitled by their subscription to initiate broadcast calls. Certain dispatchers connected to external networks also require the capability to initiate or receive broadcast calls. In addition to subscriber details in the H

36、LR, it is necessary for the mobile station to be aware of its group membership by storing details on the SIM. This is required because it shall respond to notification messages which include only the group ID (.e. no IMSI or TMSI details). Having become a group member, each service subscriber can se

37、t to active state or deactive state the group ID or any one out of his several group IDS on the SIM. In active state the subscriber can initiate broadcast calls to that group ID. When in deactive state the subscriber can not make calls to the group and the mobile station ignores any notification for

38、 that group ID. 4.2 Broadcast process 4.2.1 Broadcast call initiation 4.2.1.1 Normal operation with successful outcome A broadcast call service area can be restricted to a single MSC area or can exceed one MSC area (implementation option). A broadcast call shall be initiated by a calling subscriber

39、by a related MMI action for the service selection and the group ID dialled. The group call anchor MSC identifies (by requesting the Group Call Register (GCR, see clause 5) the service area (set of cells over which the call is to be established) together with a set of dispatchers to be included in th

40、e call. When a calling subscriber initiates a broadcast call, one broadcast call channel shall be established in each cell of the service area. At the same time standard connections to dispatchers in the mobile network or in an external network shall be established. The calling subscriber shall have

41、 an dedicated standard uplinldownlink. All mobile stations of the listening service subscribers in one cell shall only listen to the same common downlink (broadcast call channel). Only one broadcast call channel shall be established in each cell for any given broadcast call, although there may be a

42、number of simultaneous broadcast calls within the same cell. Service subscribers shall be notified with details of the broadcast call channel in each cell. These broadcast call notification messages shall be broadcast on the notification channel (NCH). The notification messages use the group ID rath

43、er than individual TMSls/lMSls. Additionally, a service area identity (service area ID) shall be included in the paging message in order to enable a resolution in the case of overlapping service areas. A service subscribers mobile station needs to be able to recognise notification messages for those

44、 group IDS subscribed to and presently activated. Page 10 GSM 03.69 Version 5.0.0: January 1996 As a network option, messages are also sent on appropriate broadcast call channel SACCHs or FACCHs, in order to notify broadcast call members who may participate in other broadcast calls. In addition , al

45、so paging information messages for standard calls may be sent in order to inform broadcast call members on actually paged point-to-point calls. As a further network option, notification on the broadcast call shall be provided to service subscribers which have subscribed to the paged group ID and whi

46、ch are in dedicated mode. The ability to react on these notification and priority information messages which are provided into on- going calls shall be a mobile station option. It shall be indicated to the mobile stations by the network if the notification and paging information on the broadcast cal

47、l channel SACCH or FACCH is provided. The process of broadcasting messages on NCHs and appropriate SACCHs or FACCHs is to be carried out throughout the call in order to provide the “late entry“ facility whereby group members entering the area can join the call. On receiving details of a broadcast ca

48、ll, a broadcast call members mobile station which is in idle mode shall adjust to the nominated channel and receive the information on the downlink. Whilst receiving, the mobile station shall not transmit on the uplink SACCH. This broadcast call receive mode is different to the normal idle mode or d

49、edicated mode. 4.2.1.2 Exceptional procedures Completion of links into congested cells where pre-emption did not occur is required. If the cell in which the calling service subscriber is located will be reset, the broadcast call shall be released. On receiving details of a broadcast call, a broadcast call members mobile station which is in dedicated mode shall automatically leave the dedicated mode and adjust to the nominated channel and receive the information on the downlink if the new call is of higher priority than the existing call and pre-emption applies.
