摘要： An apparatus and method for a radio resource control (RRC) protocol to re-establish connection in a mobile communication system environment are disclosed. A user equipment (UE), for performing connection re-establishment in a connected state with connection to a mobile communication system is provided. When a network problem occurs, the UE shall proceed with the RRC protocol connection re-establishment procedure if the security has been activated. However, if the security has not been activated and the Radio Link Control (RLC) protocol indicates the maximum number of re-transmission has been reached, the UE shall reset lower layers of the RRC protocol, release unnecessary radio resources, and indicate the release of the RRC protocol connection to upper layers of the RRC protocol. Then the UE enters the idle state and waits for the next trigger event.

摘要： A method, apparatus, and system are disclosed providing improved paging procedures in a wireless communication system. In one embodiment, a Power-down Registration signal is transmitted via a 1×RTT modem from an Access Terminal (AT) to an Access Network (AN) in a wireless communication system that includes both a 1×RTT modem and a 1×HRPD modem. The Power-down Registration signal conveys information to the AN indicating that a power-down process has been initiated by the AT, and thereby enables the AN to discontinue transmission of signals and messages to the AT that are not effective when the AT is in an off-state.

摘要： Extending acknowledgement messages from two states to at least three states is described, whereby such messages constitute a packet quality indication (PQI) reflecting quality or usability of the received signal. In an HARQ system, a transmitting station can flexibly select a better alternative for the next information to transmit on the basis of such PQI. One aspect includes determining how best to correct an unsuccessful packet transmission based on quality information about the specific packet. Implementing apparatus and procedures are described.
