The 3rd embodiment:
The 3rd embodiment is mainly the scene of disposing for the network integration, and so-called fusion disposed, and it refers to and can, by upgrading existing network SGSN to support MME, allow MME support existing network SGSN function simultaneously, reaches the fusion of existing network core net and SAE network in network element rank.According to investigation, the PS territory equipment of most manufacturer is all supported NE-level, and other merges, and fused controlling network element (MME+SGSN) can access 2G/3G and LTE user simultaneously.In the time that user terminal accesses by 2G/3G, merge network element and enable traditional SGSN function, in the time that user terminal accesses by LTE, merge network element and enable MME function.Equally, this MME/SGSN closes and establishes network element and also can resources of core network be shared by the networking mode of resource pool, and supports the access of 2G/3G user terminal and LTE user terminal simultaneously.Particularly, MME/SGSN close establish node group Pool schematic diagram as shown in Figure 9, in Fig. 9, BSC/RNC and eNodeB are linked in the resource pool of two MME/SGSN on respectively.
It is worth mentioning that, although closing, MME/SGSN establishes node for different user types, its functional role of playing the part of is different, but establish for node for a certain closing, its hardware platform and software platform have determined the combination property of a certain equipment, as support maximum adhesion user terminal number 1,000,000 (comprising 2G/3G user terminal and LTE user terminal), operator can be according to actual networking demand, as networking scale, the ratio that user model and business model etc. configure this closes maximum 2G/3G user terminal number and the maximum LTE user terminal number of establishing the required support of node, as configure at 4: 6 o'clock, to close and establish the maximum 2G/3G user terminal number that node supports be 400,000 to this MME/SGSN, correspondingly, support that maximum LTE user terminal number is 600,000.Therefore, close at MME/SGSN under the scene of establishing node group Pool, close the access of establishing node and support simultaneously BSC/RNC and eNodeB although a certain, but for BSC/RNC or eNodeB, what it obtained is only that this closes maximum load and the performance situation that node is supported under current access way of establishing, be that it is without considering that this closes user terminal number and the performance consumption situation of the current accompanying different system on node of establishing, accordingly, eNodeB MME/SGSN close establish node pool in when the LTE user terminal selecting core network node, in full accord with the scheme that the second embodiment provides.
But owing to there is no open interface between the each BSC/RNC in 2G/3G network, be that each BSC/RNC cannot intercourse the information table that it counts on, therefore, propose in the present embodiment, to in BSC/RNC, set up resource factor table, and in the time that MME/SGSN Pool is initialized, just each MME/SGSN be closed to the resource of establishing node and be handed down in advance each BSC/RNC in Pool.As supposed, each MME/SGSN closes that to establish the maximum 2G/3G user terminal number that node supported be 400,000, and in Fig. 9,2 BSC/RNC of the each access in each MME/SGSN pond, therefore, each BSC/RNC receives that it is 200,000 that each MME/SGSN closes the load factor of establishing node.Thus, in a specific BSC/RNC, will exist each MME/SGSN to close and establish the resource factor that node distributes this BSC/RNC, when BSC/RNC need to close while establishing node for a certain user terminal selecting MME/SGSN, this BSC/RNC will count by the current user terminal number that adheres to of the each MME/SGSN node in this equipment each MME/SGSN pond attached thereto, obtaining thus existing how many user terminals accesses each MME/SGSN by this BSC/RNC and closes and establish node, thereby obtaining each MME/SGSN in resource factor table closes and establishes node remaining resource in this BSC/RNC, thus, its present load situation based on MME/SGSN pond is that one of 2G/3G user terminal selecting is closed and established node.
