Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method for switching network and mobile network system, mobile management device.
Background technology
In order to strengthen following mobile network's competitiveness, third generation partner program (3GPP, The3rdGeneration Partnership Project) studying the network architecture in a kind of future, this network architecture comprises System Architecture Evolution (SAE, System Architecture Evolution) and the universal land radio access web of evolution (E-UTRAN, Evolved UMTS Terrestrial Radio Access Network).This network comprises mobile management entity (MME, Mobility Management Entity), gateway (S-GW, Serving Gateway) and three logical functional entities of grouped data network gateway (P-GW, Packet Data Network Gateway).MME is responsible for the mobile management of chain of command, comprises the management of user's context and mobile status, distributing user temporary identity sign, safety function etc.; The mobile anchor point of S-GW for switching between switching and 3GPP connecting system between local base station has management and preserves functions such as routing iinformation, Lawful Interception in IP bearing parameter and the network; P-GW is for to the gateway of external network, is used to realize the management based on strategy, and based on functions such as user's data packet filtering, charging, Lawful Interception and IP address distribution, it serves as the user's face anchor point between different access systems.
Interface use agreement between S-GW and the P-GW can be tunnel protocol (GTP, GPRSTunneling Protocol), also can be proxy mobile IP protocol (PMIP, Proxy Mobile InternetProtocol).
In the SAE system, the switching flow when reorientation takes place MME is as follows:
Steps A: subscriber equipment (UE, User Equipment) is initiated handoff request to source MME;
Step B: source MME transmits context and gives target side MME;
Step C: the switching of user plane bearer, comprise the foundation that source transmits the user plane bearer of down buffer storage data, target side to target side, the foundation of the user plane bearer of described target side comprises establishment of connection between target side S-GW and the home network P-GW.
In the above-mentioned switching flow as can be seen, target side MME does not have and local assigned user server (HSS before the target side user plane bearer is set up, Home Subscriber Server) takes place alternately, therefore can't obtain the agreement tenability of the P-GW of home network, therefore when setting up the user plane bearer of target side, may cause target side MME/SGSN can't select the P-GW of suitable S-GW and home network to connect; Even the P-GW that perhaps selects the S-GW of the two agreements of support to attempt different agreement and home network respectively connects, if the agreement of using is not that P-GW supports for the first time, can reattempt and use another kind of agreement, so also increase the time delay that successfully connects.
In addition, the tracking area update (TAU, TrackingArea Update) during MME takes place under the SAE system reorientation, also there is similar problem in the routing region updating (RAU, Routing Area Update) when reorientation takes place SGSN under the network of 2G and 3G.
Therefore, in carrying out the invention process, the inventor finds that there are the following problems at least in the prior art: the technical scheme that provides on the prior art, because the MME/SGSN of target side can't obtain the agreement tenability of the P-GW of home network in handoff procedure, cause the user plane bearer of target side to set up time delay unsuccessful or that increase is set up.
Summary of the invention
The embodiment of the invention provides a kind of method for switching network and mobile network system, mobile management device, can guarantee the user plane bearer success of target side in the network switching process and sets up fast.
