Patent ID: 8724509

Claim:
A mobile terminal including one or more processors comprising memory and being configured to be connected to a local IP network, comprising: an obtaining unit configured to receive, through an operator network, optimization information sent from a gateway in the local IP network, the optimization information comprising service information describing, for each of multiple access nodes, one or more associated services in the local IP network that can be accessed by the mobile terminal through said access node; a selecting unit configured to select one of the multiple access nodes based on the service information; a deciding unit configured to decide based on the obtained optimization information whether a path optimization to the local IP network through the access node selected by the selecting unit is to be performed, wherein the deciding includes determining whether a cell ID associated with the selected access node matches a cell ID on a list of cell ID contained in the optimization information; and an instructing unit configured to send an instruction of path optimization to the selected access node when the deciding unit decides the path optimization through the selected access node is to be performed; wherein the obtaining unit is further configured to obtain a token generated by the access node selected by the selecting unit, and the instructing unit is configured to send to the selected access node the instruction of path optimization that includes the obtained token.
