摘要： Methods and apparatus are provided for supporting Local IP Access (LIPA) services to a User Equipment (UE). A network node receives a request for accessing a PDN which is identified by an APN of a service access point, from the UE. The network node determines whether the UE is permitted to access LIPA services via a CSG base station based on LIPA accessibility information. The network node determines whether requirements for connecting the UE to the LIPA services are met based on the LIPA accessibility information and device capabilities of a serving base station of the UE, when the UE is permitted to access the LIPA services. The LIPA services are activated for the UE, when the requirements for connecting the UE to the LIPA services are met.
