After step 103, can also receive the information of the gateway of domain name system server transmission.
The executive agent of the querying method of above-mentioned gateway information can be MME.The tracking area that will belong to the same services gateway uses identical field to represent, so just can the TAI quantity of same gateway be reduced to one, thus the quantity of minimizing TAI, and then the corresponding relation list item of TAI and SGW information on the minimizing DNS Server.Also reduced simultaneously the specification of Query Result buffer memory, the TA that improves network element covers specification, saves the network element device resource consumption.
Embodiment two; In the 3GPP agreement, adhere to (Attach), tracing section updating (Tracking Area Update, TAU), switch in the flow processs such as (Handover); MME need inquire about DNS Server according to TAI and select SGW; Obtain corresponding SGW information, but while this DNS Query Result of MME buffer memory, to improve the efficient of subsequent user access process.Present embodiment will be that example describes to adhere to (Attach) flow process, and the mode of searching in other flow process is identical with the mode of searching in adhering to (Attach) flow process, and gives unnecessary details no longer one by one.
In order more to know the position of each network element in network in the embodiment of the invention; As shown in Figure 2; For a kind of typical architecture of the representative network Organization Chart of LTE/SAE for example; SGW1 and SGW2 are deployed in same share service (POOL) district, cover jointly tracking area 1 (Tracking Area1, TA1) and TA2.SGW3 is not in the POOL district, and SGW3 covers TA3 and TA4 separately.For TA1 and TA2, can select SGW1 or SGW2 to use arbitrarily, TA3 and TA4 then belong to SGW3.
The step that in layoutprocedure, needs to carry out is:
1, can plan TAI, the SGW that the high BIT bit-identify of TAI is different or one group of SGW in the different POOL district, in addition, low BIT position can be used to identify TA different in the same SGW or identify different TA in the same POOL district.The high BIT bit value of TAI in same SGW or the same POOL district coverage is identical, and low BIT bit value is different.
The process of carrying out mask code processing comprises: if high BIT figure place is designated as mask-length (being designated as N), the TAI after mask code processing is constructed as follows: N high BIT position of original TAI sign remained unchanged, and other BIT position all puts 0.According to current protocol specification, TAI length is 10 bytes, and the span of N is: 1～(10x8), and TAI is the longest like this is (10x8) BIT.
The method of the TAI of calculating after mask code processing can be, with beyond the high N position of TAI other each all make logic and operation with 1, its logical expression can for:
TAI=TAI AND after mask code processing ((2** (10x8)-1)-(2**N-1))
The logical expression of the TAI of aforementioned calculation after mask code processing can remain unchanged the high N of TAI position other position 0.
Certainly for the TAI that will have identical high BIT position is treated to identical TAI, the N position that can also directly read high BIT position is as the TAI after mask code processing.The concrete implementation embodiment of the invention that the TAI that will have an identical high BIT position is treated to identical TAI will not limit.
Corresponding to the situation of Fig. 2, SGW1 among the POOL1 and SGW2 are with same TAI sign after mask code processing, and SGW3 is with the independent TAI sign after mask code processing.
2, operator's configuration DNS Server, the corresponding relation file of TAI after DNS Server issues mask code processing and SGW Hostname, IP can issue with the form of table.
In DNS Server configuration, the mapping table of the TAI after mask code processing, SGW Hostname, IP is as shown in table 1:
Table 1
| TAI after mask code processing | SGW?Hostname | SGW?IP |
Like this, only need the corresponding relation of the TAI of configuration after mask code processing and SGW Hostname, IP on the DNS Server, the quantity of configuration is reduced to original N/ (10x8), can significantly reduce the quantity of configuration, the efficient of increase configuration effort.
What 3, operator will dispose sends to DNS Server through the TAI of mask code processing and the corresponding relation of SGW and gateway, issues mask-length (N) to MME or DNS Server.
In Attach (adhering to), TAU (tracing section updating), Handover operation flows such as (switchings); MME or DNS Server carry out mask code processing with the TAI that obtains; TAI after mask code processing is constructed as follows: N high BIT position remains unchanged, and other low BIT position is 0.With the inquiry of the TAI after mask code processing DNS Server (referring to the Attach flow process of back), obtain corresponding SGW Hostname, IP then.
In the layoutprocedure of above-mentioned operator to TAI; Distribute certain TAI scope also can for one group of SGW in each SGW or each the POOL district; Different TAI identifies different TA in same SGW or the same POOL district in this scope, the TAI scope phase non-overlapping copies in different SGW or different POOL district.The TAI scope is identified by initial TAI, end TAI.Corresponding to the situation of last figure, the SGW1 among the POOL1 distributes identical TAI scope with SGW2, and SGW3 distributes the independent TAI scope of another one.
In the process of the configuration DNS Server of above-mentioned operator, then issue the corresponding relation of TAI scope (initial TAI, finish TAI) and SGW Hostname, IP to DNS Server.
Dispose at DNS Server: the mapping table of TAI scope (initial TAI, end TAI), SGW Hostname, IP is as shown in table 2:
Table 2
| Initial TAI | Finish TAI | SGW?Hostname | SGW?IP |
In the time of operator's configuring MME or DNS Server, then issue the TAI scope (initial TAI, finish TAI) of configuration to MME or DNS Server.
Adhere to searching in (Attach) flow process, as shown in Figure 3, comprising:
301: (User Equipment UE) sends connection request (Attach Request) message to eNodeB to subscriber equipment;
302:eNodeB sends user's initial message (INITIAL UE MESSAGE) to MME and wherein carries Attach Request message and TAI;
After 303:MME receives Attach Request message, according to TAI or the TAI after mask code processing or TAI scope (initial TAI, finish TAI) to the corresponding SGW of DNS Server inquiry;
If send the TAI after mask code processing, need the TAI in the step 302 be carried out mask code processing so, and the TAI after mask code processing is sent to DNS Server, concrete mask code processing mode can be with reference to the description in 1.
The information of 304:DNS Server inquiry SGW is also returned Query Result and is given MME;
Concrete querying method can for:
If that receive is the TAI after mask code processing, so directly search the information of corresponding gateway according to above-mentioned tracking area identification after mask code processing;
If that receive is TAI, according to above-mentioned rule of mask code processing the above-mentioned tracking area identification that receives is carried out mask code processing so earlier, search the information of corresponding gateway then according to the tracking area identification after mask code processing;
If what receive is the TAI scope,, can directly search the information of the corresponding gateway of the TAI after mask code processing of this scope so if initial TAI, finish TAI through the mask code processing mistake; If initial TAI, finish TAI not through the mask code processing mistake, then earlier to initial TAI, finish TAI and carry out mask code processing, and then search the information of the corresponding gateway of the TAI after mask code processing of this scope.
305:MME sends to SGW and creates default bearing request (Create Default Bearer Request) message;
306:SGW selects local terminal S1-U IP address, and (PDN Gateway PGW) sends Create Default Bearer Request message to PDN Gateway then;
307:PGW responds and creates default bearing response (Create Default Bearer Response) message;
308:SGW sends Create Default Bearer Response message to MME, carries the local terminal S1-U IP address that the front is selected;
309:MME sends to eNodeB and adheres to acceptance (Attach Accept) message, the S1-U IP address of carrying SGW;
310:eNodeB obtains the S1-U IP address of S-GW from Attach Accept message, transmit Attach Accept message to UE then;
311:UE sends to eNodeB and adheres to completion (Attach Complete) message;
312:eNodeB transmits Attach Complete message to MME;
313:MME sends more new bearer request (Update Bearer Request) message to S-GW;
314:S-GW responds more new bearer response (Update Bearer Response) message.
