    摘要: A method and apparatus are described for maintaining communications connectivity for client applications that send keep-alive messages and network applications that send client-alive (i.e., “are you there?”) messages. The client applications may register with a client proxy provided in an operating system (OS) of a wireless transmit/receive unit (WTRU) and indicate a respective keep-alive message signaling rate. The network applications may register with a network proxy provided in an OS of a network node and indicate a respective client-alive message signaling rate. The client proxy and/or the network proxy may, respectively, register and prioritize keep-alive and/or client-alive message requirements, determine an optimal signaling rate based on the respective keep-alive and/or client-alive message signaling rates, and generate proxy messages, (i.e., an application layer proxy keep-alive message and/or a network layer proxy client-alive message), associated with the keep-alive and/or client-alive messages. The proxy messages may be transmitted at the optimal signaling rate.

    摘要: The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.

    摘要: A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.
