The practical application of method in access control of obtaining the MS signing-contract field information with prior art is example below, introduces the method that prior art is obtained the MS signing-contract field information in detail.
Suppose that SGSN only administers the PLMN that PLMN ID is PLMN A, when MS attempted Location Area Identification from PLMN A (LAI) and inserts SGSN for the zone of LAIA_2, the VPLMN of MS was PLMNA.
In this case, HLR determines that according to the SGSN address VPLMN of MS is PLMN A after receiving location update request message from SGSN, searches the signatory ZC of MS under PLMN A in the signatory ZC table of MS.Table 1 is the signatory ZC tabulation of MS.
| PLMN ID | ZC |
| PLMN A | ZC A_1 |
| PLMN A | ZC A_2 |
| PLMN B | ZC A_3 |
Table 1
As known from Table 1, the ZC of PLMN A correspondence comprises ZC A_1 and ZC A_2, and correspondingly, the signatory ZC of MS under PLMN A comprises ZC A_1 and ZC A_2, and HLR sends in the insertion subscription data message of SGSN will carry ZC A_1 and ZC A_2.
When SGSN receives the signatory ZC of MS under PLMN A, that is behind ZC A_1 and the ZC A_2, judge according to the ZC tabulation of the PLMN A that is stored whether the ZC in MS zone of living in is included among the signatory ZC of MS under PLMN A.Table 2 is ZC tabulations of PLMN A, has listed the corresponding relation between the ZC and LAI and route area code (RAC) in PLMN A in the table, and wherein RAC is an option, usually, and the minimum corresponding route district of ZC, lane place of correspondences at most.
| ZC | LAI | RAC |
| ZC A_1 | LAI A_1 | RAC A_1 |
| ZC A_2 | LAI A_2 | RAC A_2 |
| ZC A_3 | LAI A_3 |
Table 2
As known from Table 2, the ZC of LAI A_2 correspondence is ZC A_2, simultaneously, comprises ZC A_2 among the signatory ZC of the MS that SGSN receives under PLMN A, and significantly, MS zone of living in is included in MS in the signing-contract field under the PLMNA.Therefore, will to allow MS be that the zone of LAI A_2 is inserted from LAI to SGSN.
As seen, in the GPRS network of a PLMN of a SGSN administration, because SGSN and PLMN concern one to one, so HLR gets final product the VPLMN ID of unique definite MS according to the SGSN address, thereby the signatory ZC of MS under VPLMN sent to SGSN, so that SGSN judges whether to allow MS to insert from zone of living in.
But networking for convenience of current operator and the consideration that reduces cost need a kind of GPRS network by an above PLMN of a SGSN administration.In this GPRS network, obtain the method for MS signing-contract field information if still adopt prior art, following problem will appear: because SGSN and PLMN concern one to one, but corresponding above PLMN of SGSN, so HLR can't determine the VPLMN ID of MS also just the signatory ZC of MS under VPLMN can't be sent to SGSN, correspondingly according to the SGSN address, SGSN can't judge whether to allow MS to insert from zone of living in, causes SGSN can't control the access of MS effectively.
