In first embodiment of the invention, can consider by media gateway MGW as distribution node, particularly, as shown in Figure 6 as the concrete sketch map of distribution node by MGW.As MGW during as distribution node; It can add up the TMSI of each user terminal that adheres in the above; And from the NRI field, read the sign (MSC-ID) of each MSC under MSC POOL-ID and this MSC POOL-ID respectively; Calculate pairing TMSI number, i.e. terminal use's number under a certain specific MSC-ID among a certain specific MSC POOL-ID at last.Carry out this process repeatedly, this MGW just can obtain the user terminal number under each MSC in each MSC Pool of current its first line of a couplet, and is organized into an information table as shown in table 1:
Table 1:
| The sign of the MSC that MSC POOL- |
MSC-ID1 | MSC-ID2 | MSC-ID3 |
| The number of the user terminal that adheres to | 400,000 | 600,000 | 500,000 |
| The sign of the MSC that MSC POOL- |
MSC-ID4 | MSC-ID5 | MSC-ID6 |
| The number of the user terminal that adheres to | 300,000 | 500,000 | 600,000 |
Each MGW can send the information table that himself counts to other MGW broadcasting respectively; Be that each MGW can be through intercoursing this information table and the tabulate statistics of classifying; Make that each MGW can perception and obtain the number of the current user terminal that is connected of each MSC in each MSC Pool of its first line of a couplet; Whole statistics flow process is seen shown in Figure 7, comprises step:
Step 71, MGW obtains the TMSI that user terminal UE sends, and from the NRI field of TMSI, obtains the sign of MSC Pool resource pool;
POOL-ID for not the time, continues execution in step 71 in judged result, otherwise, execution in step 73;
In first embodiment of the invention, through in the TMSI of user terminal to send up, carrying MSC
The method of POOL-ID makes each MGW can obtain the user terminal number that each MSC is connected in each MSC Pool of its first line of a couplet, thereby determines the load information of each MSC Pool.The benefit that MGW determines the load information of each MSC Pool is that when the load of certain MSC Pool was overweight, MGW can be according to the load information of other MSC Pool, and selecting another suitable MSC Pool is that user terminal provides service.
In addition; In first embodiment of the invention; The advantage of carrying MSC POOL-ID with the NRI field also is; Because user terminal can cause the change (comprising the change of MSC POOL-ID and MSC-ID) of the NRI field among the TMSI when going out, going into MSC Pool; And can send response message to MGW, MGW just can go out, go into dynamically obtain user terminal in the MSC Pool MSC that is connected, the identification information of MSC Pool the user like this, and the statistics of the user terminal number of realizing again MSC/MSC Pool is connected.
Second embodiment:
Similar with MSC Pool, under the scene of MME Pool, that network node sign and user terminal identification adopt usually is GUTI.MMEGI among the GUTI, MMEC and M-TMSI field are indicated the sign in MME pond, the sign of MME and the sign of the user terminal that this MME connected respectively.Particularly, the enforcement scene of second embodiment is as shown in Figure 8.Wherein, eNodeB is the distribution node described in the method that provides of the embodiment of the invention.
ENodeB is when confirming the load information of MME; Can be to the GUTI that sends attached to each user terminal on the MME; From GUTI, read each MMEC under MMEGI and this MMEGI respectively; Thereby obtain the pairing M-TMSI number of a certain specific MMEC among a certain specific MMEGI, i.e. the number of user terminal.Carry out this process repeatedly, eNodeB just can obtain the user terminal number under each MME in current each MMEPool of its first line of a couplet.Further; Each eNodeB can also combine its bearer context of receiving to set up request message; Count current default bearing number that activates of user terminal and dedicated bearer number in each MME in each MME Pool of its first line of a couplet, and be organized into an information table as shown in table 2.
Table 2
In conjunction with the intercommunication flow process between the eNodeB; Such as; Each eNodeB sends the information table that self counts based on X2 interface as shown in Figure 8 to other eNodeB broadcasting; Be that each eNodeB can be through intercoursing this information table and the tabulate statistics of classifying; Make each eNodeB can perception with obtain each MME Pool of its first line of a couplet in the current user terminal number that is connected under each MME, and current dedicated bearer number that activates of each user terminal and default bearing number, thus each eNodeB can realize estimating the load information of each MME in each MME pond of its first line of a couplet; Thereby the comprehensive information of each MME, the MME that serves for user terminal selecting or initiate the load migration flow process come balance resources of core network pond in load.
The 3rd embodiment:
The 3rd embodiment mainly is the scene of disposing to the network integration, and so-called the fusion disposed, and it is meant and can lets MME support existing network SGSN function simultaneously through upgrading existing network SGSN to support MME, reaches the fusion of existing network core net and SAE network in the network element rank.According to investigation, the PS territory equipment of present most of manufacturers is all supported other fusion of NE-level, merges control network element (MME+SGSN) and can insert 2G/3G and LTE user simultaneously.When user terminal inserts through 2G/3G, merge network element and launch traditional SGSN function, when user terminal inserts through LTE, merge network element and launch the MME function.Equally, this MME/SGSN closes and establishes network element resources of core network is shared, and supports the access of 2G/3G user terminal and LTE user terminal simultaneously.Particularly, it is as shown in Figure 9 that MME/SGSN closes the sketch map of establishing groups of nodes Pool, and in Fig. 9, BSC/RNC and eNodeB are linked in the resource pool of two MME/SGSN on respectively.
What deserves to be mentioned is; Establish node to different user types though MME/SGSN closes, its functional role of playing the part of has nothing in common with each other, and establishes for the node for a certain closing; Its hardware platform and software platform have determined the combination property of a certain equipment; As supporting 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, waits like networking scale, user model and business model and disposes this and close the maximum 2G/3G user terminal number of establishing the required support of node and the ratio of maximum LTE user terminal number; As disposed 4: 6 o'clock; Then 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 under the scene of establishing groups of nodes Pool at MME/SGSN; Though a certain closing established the access that node is supported BSC/RNC and eNodeB simultaneously, for BSC/RNC or eNodeB, what it obtained only is that this closes maximum load and the performance situation that node is supported of establishing under current access way; Be that it need not to consider that this closes the user terminal number and the performance consumption situation of establishing current appended different system on the node; In view of the above, eNodeB closes when establishing in the node pool to LTE user terminal selecting core network node at MME/SGSN, and is in full accord with the scheme that second embodiment is provided.
But owing to do not have open interface between each BSC/RNC in the 2G/3G network; Be that each BSC/RNC can't intercourse the information table that it counts on; Therefore; Propose in the present embodiment, will in BSC/RNC, set up the resource factor table, when MME/SGSN Pool is initialized, just each MME/SGSN is closed the resource of establishing node and be handed down to each BSC/RNC in the Pool in advance.As suppose that each MME/SGSN closes that to establish the maximum 2G/3G user terminal number that node supports be 400,000; And in Fig. 9; 2 BSC/RNC are respectively inserted in each MME/SGSN pond, and therefore, each BSC/RNC receives that it is 200,000 that each MME/SGSN closes the load factor of establishing node.Thus; Will exist each MME/SGSN to close among the specific BSC/RNC and establish the resource factor that node distributes this BSC/RNC; When BSC/RNC need close when establishing node for a certain user terminal selecting MME/SGSN; This BSC/RNC will count through this equipment attached to the current user terminal number that adheres to of each the MME/SGSN node in each MME/SGSN pond of its first line of a couplet; Obtaining existing how many user terminals thus inserts each MME/SGSN through this BSC/RNC and closes and establish node; Close and establish node residual resource in this BSC/RNC thereby obtain each MME/SGSN in the resource factor table, thus, its present load situation based on the MME/SGSN pond is that one of 2G/3G user terminal selecting is closed and established node.
