求解答。
刚咨询了厂家,答复BVCI是由PCU资源框进行分配,然后上报给SGSN,由SGSN来创建维护小区列表。
求 ...
这个解答是对的。SGSN上不需要创建,都是BSC报上来的。应该是唯一的标识小区。48018里是这么说的: “Within the present document, a cell is identified by a BVCI unless it is explicitly stated otherwise.” 看看这个两个相同的BVCI是在同一个BSC或SGSN上发现的吗?还是不同的BSC上发现的? 另外,关于创建和取值是这么说的: “Each BVC is identified by means of a BSSGP Virtual Connection Identifier (BVCI) which has end-to-end significance across the Gb interface. Each BVCI is unique between two peer Network Service Entities. In the BSS, it shall be possible to configure BVCIs statically by administrative means, or dynamically. In case of dynamic configuration, the BSSGP shall accept any BVCI passed by the underlying Network Service entity. At the SGSN side, BVCIs associated with PTP functional entities shall be dynamically configured. The BVCIs associated with signalling functional entities and PTM functional entities are statically configured.” The BVCI value 0000 hex shall be used for the signalling functional entities. The BVCI value 0001 hex shall be used for the PTM functional entities. All other values may be used freely by the BSS and shall be accepted by the SGSN. |
