Description
Technical field
The present invention relates to network communications technology field, relate in particular to and realize the directed system and method that connects in a kind of mobile communications network.
Background technology
Be linked into outer data network after 3GPP (third generation partner program) mobile communications network can provide portable terminal to activate, the ability of data service is provided, for example existing network communication systems such as GPRS, TDS-CDMA, WCDMA all can be portable terminal provides data service.
Existing is the activation and the connection procedure of example explanation portable terminal with GPRS.As shown in Figure 1, the network side nucleus equipment of gprs system has comprised serving GPRS support node SGSN and gateway support node GGSN.According to the 3GPP standard, portable terminal is before activating online, and is as shown in Figure 2, generally needs on the terminal, to accomplish access point APN (Access Point Name) parameter setting in advance, just initiates PDP (packet data protocol) context activation signaling process then.In the APN field in PDP context activation demand signalling message, just comprised the APN parameter that the terminal is provided with in advance, but this field also possibly be sky.The PDP context activation demand signalling that portable terminal is initiated sends to serving GPRS support node SGSN (see figure 1) through wireless access network and Gb Interface.Serving GPRS support node SGSN initiates the domain name mapping request to this APN parameter to domain name server (DNS) after receiving the PDP context activation demand signalling, selecting the flow processing success through inner APN; Domain name server (DNS) will respond the IP address that a group (one or more) represented intended gateway support node GGSN to serving GPRS support node SGSN under the success situation.Serving GPRS support node SGSN selects one of them IP address, initiates PDP Context establishment demand signalling through GPRS Tunnel Protocol signaling plane (GTP-C) to the gateway support node GGSN of this IP address representative then, proceeds whole activation process (see figure 2) to accomplish the foundation of GPRS Tunnel Protocol user plane (GTP-U).Therefore, in activation, the selection of gateway support node GGSN was through being that the domain name addresses that indicates is resolved and realized with APN during communication connected, thus the communication of serving GPRS support node SGSN and gateway support node GGSN to be connected be dynamic.
Generally speaking; Take an APN to resolve the IP address mode of corresponding a plurality of gateway support node GGSN; To form the networking mode of GGSN pond groupization; Therefore initiate PDP Context and create the serving GPRS support node SGSN of demand signalling and be and GGSN pond group forms corresponding relation, and the communication of serving GPRS support node SGSN and concrete gateway support node GGSN is connected by each activation definite temporarily.The dynamic annexation of serving GPRS support node SGSN and gateway support node GGSN has increased the flexibility of network configuration, can realize GGSN load sharing and redundancy feature.
Yet pond group networking is safeguarded the network operation with dynamic connected mode has increased difficulty, particularly the network service test has been caused obstacle.In the network operation is safeguarded; Operator generally takes various means of testing (for example terminal testing, emulation testing) to initiate quality of service detection and troubleshooting; But owing to lack concrete connection that serving GPRS support node SGSN and particular gateway support node GGSN in each activation are confirmed or specified to effective means; Therefore still can't the finished surface traversal that independent individual is connected with appointment in the group of GGSN pond detect demand at present, can't realize that also the necessary orientation of fault location connects test request.Therefore, existing network communication system power of test is low at present, can only be to accomplish detection of network connecting part traversal and fault location discovery test through substantive test work.
