14、07 Bbb II Page 7 GSM 03.49 version 5.7.0 Release 1996: July 1998 1 scope No mandatory protocol between the Cell Broadcast Centre (CBC) and the Base Station Controller (BSC) is specified by GSM; this is a matter of agreement between CBC and PLMN operators. This Global System for Mobile communications

15、 Technical Specification (GTS) specifies three alternative approaches to the specification of protocol stacks of communication protocols for the purpose of fulfilling the service requirements of the primitives specified for the CBC - BSC interface in GSM 03.41. One approach is based upon the use of

16、the complete OS1 reference model (see X.200), another approach is based upon the use of only the lower 3 OS1 layers, and another approach is based upon the use of CCITT Signalling System No. 7 (see Q.700). Specifications are based upon individual contributions. Any judgement concerning functionality

17、, completeness and advantages/disadvantages of implementation is intentionally omitted. 1.1 References This GTS incorporates by dated and undated reference, provisions from other publications. These references are cited at the appropriate places in the text and the publications are listed hereafter.

18、 For dated references, subsequent amendments to or revisions of any of these publications apply to this GTS only when incorporated in it by amendment or revision.

Note: This PDU should be used in the case of a Phase 2+ entity communicating with a Phase 2 entity. CBSE-VBIND This operation must

30、 be invoked by the party which is responsible for establishing the application association; only after the application association has been established may the remaining CBSE services be used.

33、he network layer does not support NS-user-data of 128 octets then CBSE-BIND-CONFIRM may be carried as the second N-DATA requesindication following establishment of the network layer connection - see Section 2.4). On receipt of a CBSE-BIND PDU, the recipient must assume that the sender is supporting

34、the Phase 2 version of the interface and must reply with an untagged CBSE-BIND-CONFIRM. If a CBSE-VBIND PDU is received, the recipient must reply with a tagged CBSE-BIND-CONFIRM as a substructure of CBSEapdus.
