With reference to figure 1, it shows the schematic diagram of system 100, and for example, this system 100 can be the part of public-land mobile network (PLMN).According to embodiments of the invention, service universal grouping wireless serving GPRS support node (SGSN) 105 receives connection request from mobile radio station (MS) 115.SGSN 105 is from the subscription data of attaching position register (HLR) 120 requests about MS 115 afterwards.HLR 120 uses international mobile subscriber sign (IMSI) sign indicating number identification MS 115.Afterwards, the subscriber data message of HLR 120 through inserting will send to SGSN 105 about the subscription data of the request of MS 115, and these customized and data comprise a plurality of APNs (APN).HLR120 can be included among the identical PLMN with SGSN 105, and perhaps, in the situation of MS 115 roamings, HLR 120 and SGSN 105 can be in different PLMN.
Afterwards, with reference to figure 2, it is according to embodiments of the invention, comprises that two tables 205,210 schematic diagram, these two tables are about the activation environment custom at SGSN 105 places that are associated with a plurality of MS.Table 205 is included in the example lists of nine pre-configured general packet data protocol (PDP) environment customs at SGSN 105 places.Nine pre-configured general PDP environment customs are labeled as " C1 " arrive " C9 ".General PDP environment custom is relevant with general APN, and it relates to a plurality of MS subscribers.According to the present invention, pre-configured this general PDP environment custom makes that relevant subscription data can be repeated to add and activate at SGSN 105 places, and is deactivated afterwards and deletes from mobile management (MM) environment table.As described below, this makes has saved memory in fact at SGSN 105.
The table 210 of Fig. 2 shows the example lists of MS GPRS Mobility Management (MM) the environment table that is used for SGSN 105.The environment tabular that is used for SGSN 105 has gone out the PDP environment that each MS 115 with the current SGSN of being connected to 105 is associated.The MM environment that SGSN 105 will be used for all MS 115 usually and PDP environmental information remain on standby (STANDBY), ready (READY), PMM-free time (PMM-IDLE) and are connected (PMM-CONNECTED) state with PMM-.Therefore, for example, shown in table 210, for a MS 115 of mark " MS1 ", the MS GMM environment table of SGSN 105 comprises a MS specific PDP environment custom data of GMM environment, mark " S1 " and the first general PDP environment custom data of mark " C1 ".
Refer again to Fig. 1, after the HLR 120 about MS 115 received subscription data, each APN that SGSN 105 determines to be included in the subscription data was relevant with general PDP environment custom or relevant with the specific PDP environment custom of MS at SGSN 105.If concrete APN is relevant with the specific PDP environment custom of MS, the specific PDP environment custom of MS data is written into and is stored in the MS GMM environment table in the memory 130, wherein this memory 130 SGSN 105 that is operably connected.But if concrete APN is relevant with general PDP environment custom, ignorance APN and general PDP environment custom data that will be not relevant with that APN are written into or are stored in the memory 130.Memory 130 can comprise any one in the multiple computer-readable medium, and can be integrated or discrete with SGSN 105 with SGSN 105.
Therefore, the method for differentiation of the present invention general PDP environment custom data and the specific PDP environment custom of MS data has reduced the desired volume of the memory 130 that is associated with SGSN 105 in fact.According to the standard and the process of prior art, when MS 115 was connected to SGSN 105, all APN of that MS 115 that configuration are used for its HLR 120 were written into the memory 130 that is associated with SGSN105 and are stored in wherein.This makes that general PDP environment custom data (in a plurality of subscribers identical data) are duplicated for each subscriber.Can significantly save memory according to the present invention, because according to prior art, APN for each interpolation, MS 115 will add new PDP environment custom record, it comprises a plurality of fields, such as the VPLMN address of PDP type, pdp address, APN, customized QoS configuration file, permission, PDP content fee with characteristic etc.According to the present invention, in the memory 130 that is associated with SGSN 105, do not need to duplicate these fields.
After MS 115 finishes the process that is connected to SGSN 105, give SGSN 105 by at first sending " creating the PDP environment " request, MS 115 can set up the communication channel with grouped data networking (PDN).According to the present invention, the PDP environment of determining request after the SGSN 105 is to be associated with general PDP environment custom or to be associated with the specific PDP environment custom of MS.If request and general PDP environment custom are associated, so at first general PDP environment are added to MS GMM environment table and also activate afterwards.As mentioned above, if the specific PDP environment custom of this request and MS is associated, this environment exists in MS GMM environment table so, because during connection procedure it is written into and is stored in there, and therefore activates environment simply.
The establishment PDP context request message that SGSN 105 transmissions afterwards comprise relevant APN is to Gateway GPRS Support Node (GGSN) 135, and it is relevant with PDN 145, and MS 115 attempts setting up by this PDN 145 and communicates by letter.After the GGSN 135 new environment is added in its PDP environment table.New afterwards environment allows GGSN 135 to be based upon the path of the PDP Packet Data Unit (PDU) between MS 115 and the target P DN145.
After the communication of finishing between MS 115 and PDN 145, SGSN 105 is used for the PDP environment of current APN.Determine after the SGSN 105 that the PDP environment of stopping using is to be associated with general PDP environment custom or to be associated with the specific PDP environment custom of MS.If environment and general PDP environment custom are associated, so from the general PDP environment custom of MS GMM environment list deletion data.This in the table 210 of Fig. 2 shown in frame of broken lines 215, its show stop using and deletion about general PDP environment custom C2, C3, C7 and the C8 of mobile radio station MS2.Those skilled in the art will also recognize that this general PDP environment custom data of deletion can save the storage space in the memory 130 that is associated with SGSN 105 in fact.
If the PDP environment and the specific PDP environment custom of MS of stopping using are associated, so can be from MS GMM environment list deletion subscription data, because during MS 115 remains connected to SGSN105, may need these data specific PDP environment custom of MS of stopping using.The specific PDP environment custom of this MS generally includes service quality (QoS) configuration file of the uniqueness that is associated with single AP N.
Those of ordinary skills further discern the memory 130 that the present invention not only more effectively uses and SGSN 105 is associated, and it realizes that this purpose does not have a negative impact to connection speed or the activation/speed of stopping using simultaneously.For given HLR 120, therefore, the authentication quantity of the APN of each MS 115 can increase and the modification that can not sacrifice network performance and not need arbitrary network hardware.Because the change that the present invention needs is in each SGSN 105 localization of network, the standard interface between SGSN 105 and other network node (such as HLR 120 and GGSN 135) remains unaffected.
