Patent ID: 8730831

Claim:
A method for acquiring a routing strategy comprising: when the routing strategy is for a radio side network element, locally configuring a general routing strategy by a mobility management element for the radio side network element, and when a user's local IP access function is enabled, sending the general routing strategy for the radio side network element to the radio side network element; when the routing strategy is for a user, receiving and storing the routing strategy by the mobility management element for the user sent from a home subscriber server (HSS) at the time of the user registering to a network or initiating a location update, and when the user's local IP access function is enabled, sending the routing strategy for the user to the radio side network element; wherein, (i) the radio side network element is a data offload function unit, a home NodeB, a home evolved NodeB (H(e)NB), a macro base station, or a H(e)NB gateway which is equipped with the data offload function unit; (ii) the mobility management element is a serving General Packet Radio Service support node (SGSN) or a mobility management entity (MME); and (iii) the routing strategy is a corresponding relationship between a packet destination address and two routing options of a local IP access or a core network access, or a relationship between a routing option and a local IP access type, wherein the local IP access type is local IP access to the Internet or local IP access to a home network.
