摘要： Systems and methods for improving data delivery latency in a wireless communication system are disclosed. The method and system can include transmitting a data over signaling (DOS) message to an access terminal in a first portion of a paging zone estimated to contain the access terminal and paging the access terminal in other portions of the paging zone.

摘要： A server based method for optimizing call setup latency including updating client location information using at least one application server; identifying and updating parameters including location update information uniquely identifying a sector from which the at least one client is receiving communication service; determining at least one geographically dense call group; choosing at least one designated responder to respond to the at least one call group; selecting a plurality of designated responders as targets for m largest clusters; computing hash outputs of the targets; and performing a logical OR operation on lower order n bits of the hash outputs corresponding to the targets.

摘要： An apparatus and method for efficiently updating location information of a mobile device in a wireless communication network, such as a cellular network, is disclosed. The mobile device sends its location information through a route update message to a base station controller. This route update message is sent over the access channel if the traffic channel is not up. When the base station controller realizes the mobile device has changed its location, the base station notifies the change to a location server, which sends a location update message to an application server.

摘要： Aspects of mobile communication for establishing a receive-only group communication, such as a Push-to-Talk (PTT) call or multicast call with a plurality of wireless communication devices that are in a receive-only mode are disclosed. When a group call between wireless communication devices starts from an originating device, in one embodiment indicating a receive-only group with which a group call is to be established, one or more receive-only wireless communication devices are determined and invited to participate in the group call. The traffic channel to the receive-only wireless communication device is transitioned to a uni-directional, forward-only traffic channel such that media is provided from the originating wireless communication device to the receive-only wireless communication device via the uni-directional traffic channel.

摘要： An apparatus and method for efficiently updating location information of a mobile device in a wireless communication network, such as a cellular network, is disclosed. The mobile device sends a location message over an access channel. The wireless communication device continually transmits a location message at periodic intervals regards of the status of the base station in communication with the wireless communication device. The base station determines a timeslot in which to receive a location message transmitted by the wireless communication device. If more than one wireless communication device is transmitting a location message, the base station prioritizes the order in which to receive the location message, opening the first available timeslot to the higher priority wireless communication device. A high priority device may be a wireless communication device used by emergency services personnel, such as firefighters or the police.
