摘要： System and method embodiments are provided for accessing a wireless network. The embodiments enable establishing and releasing session resources in a wireless local area network (WLAN) corresponding to packet data network (PDN) connections in a 3 GPP enhanced packet core (EPC). In an embodiment, a method in a network component for establishing a control channel with a user equipment (UE) includes setting up, by the network component, a link layer channel, sending, by the network component, an identifier of the link layer channel to the UE; and communicating, by the network component, with the UE over the link layer channel using a WLAN control protocol (WLCP), wherein the WLAN comprises a trusted WLAN Access Network (TWAN).

摘要： The present invention discloses a method and a device for handover to a serving network. The method includes: receiving a first Handover Request sent by a BSC/RNC; sending a second Handover Request to a target MME according to the first Handover Request, where the second Handover Request includes an IMSI and first information for determining a source SGSN so that the MME sends a Context Request message including the IMSI to the source SGSN and receives context information of a user equipment corresponding to the IMSI sent by the source SGSN. The device includes an MSC server, an SGSN, an MME, and a BSC/RNC. The method and apparatus according to embodiments of the present invention, by applying for context information from a source SGSN by using an MME determined by an MSC server, are capable of ensuring that, in an rSRVCC handover process, the MSC server and the SGSN interact with the same MME, thereby avoiding a handover failure because the MSC server and the SGSN select different MMEs, and further synchronizing PS and CS handover processes, improving handover accuracy and efficiency, and enhancing user experience.

摘要： System and method embodiments are provided for optimizing offloading wireless services to a WLAN in 3GPP-RAT mobility. The embodiments enable changing network priority based on changing network conditions. In an embodiment, a method in a user equipment (UE) for offloading wireless services to a wireless local area network (WLAN) in a Third Generation Partnership Project (3GPP) inter-radio access technology (RAT) handover includes receiving an access network discovery and selection function (ANDSF) policy from an ANDSF server, wherein the ANDSF policy comprises policy rules including a validity condition, wherein the receiving is performed during a procedure in which the UE conducts an inter-RAT handoff from a first 3GPP RAT to a second 3GPP RAT; comparing evaluation condition information for the second 3GPP RAT against the validity condition; and offloading a first wireless service to the WLAN in accordance with the ANDSF policy when the validity condition is satisfied.
