Disclosed are a method and apparatus for load balancing, which relate to the field of network management and are used to solve the problem of the unbalanced utilization of resources occupied by an individual operator on P-GWs caused by selecting a P-GW merely according to weight information about the plurality of P-GWs having the same APN when an MME requests to access the P-GW. The method provided in the present invention comprises: acquiring an APN according to a PDN connection request, querying a P-GW list composed by P-GWs corresponding to the APN, and selecting a P-GW to establish a PDN connection according to P-GW identifiers of the P-GWs and the resource throughput capability level and bearing amount of the P-GWs in the list, and the resource throughput capability level and bearing amount occupied by an operator corresponding to the APN on the P-GWs. The embodiments of the present invention are mainly applied to a process for establishing a PDN connection. |
