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 without regards to 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.

摘要： Embodiments are directed to determining whether one or more physical user interactions are present, at a wireless communication device, that indicate a near-future potential communication session resource request. Before the determination, a communication interface of the device is in a dormant state characterized by the device not being permitted to engage in a communication session with a wireless communication network. The device transitions the communication interface, after the determination, from the dormant state to an active state. In the active state, the device performs one or more actions to reduce a delay associated with a transmission of the potential communication session resource request in the event that the potential communication session resource request is actually transmitted by the device. For example, in the active state, the device can power-up or wake-up a radio bearer or modem to reduce a delay before transmission of the potential communication session resource request.
摘要翻译： 实施例涉及确定在无线通信设备处是否存在指示近期潜在通信会话资源请求的一个或多个物理用户交互。 在确定之前，设备的通信接口处于休眠状态，其特征在于该设备不被允许与无线通信网络进行通信会话。 该设备在确定之后将通信接口从休眠状态转换到活动状态。 在活动状态下，在由设备实际发送潜在通信会话资源请求的情况下，设备执行一个或多个动作以减少与潜在通信会话资源请求的传输相关联的延迟。 例如，在活动状态下，设备可以上电或唤醒无线电承载或调制解调器，以在发送潜在通信会话资源请求之前减少延迟。

摘要： A system and method for signaling and delivering group communication data, such as push-to-talk (PTT) setup data, to a dormant wireless telecommunication device across a control channel on a wireless communication network. Each wireless telecommunication device is able to direct a single group communication stream to a designated target group of other wireless telecommunication devices, and the wireless telecommunication device has a dormant state in which the wireless telecommunication devices bridges a control channel with a communication server and an active state in which the wireless telecommunication device bridges a dedicated communication channel with the communication server. The wireless telecommunication device receives group communication setup data though a control channel for incoming group communications, and such delivery occurring without fully bridging a dedicated communication channel to that wireless telecommunication device.

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： In group wireless telecommunication, such as push-to-talk (PTT) calls, a voice communication is broadcast through Internet protocol data packets to other member devices of the PTT group. At least one communication server receives a single communication stream from a communicating wireless device, such as a PTT call, and creates a group communication to all wireless telecommunication devices of the designated group with the broadcast of Internet protocol data packets containing the voice data of the communication stream to one or more wireless telecommunication devices of the receiving group that can receive and handle the packets. Other wireless network infrastructure can be used to assist the communication server in generation and broadcast of the Internet protocol data packets to the receiving wireless telecommunication devices.

摘要： In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The target device indicates its acceptance of the half-duplex session, receives half-duplex media from the originating device and selectively indicates its acceptance of the full-duplex session. In another embodiment, during a session currently supported either by half-duplex or full-duplex, the server arbitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.

摘要： A system and method for minimizing latency for direct group communications, such as push-to-talk (PIT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device selectively requests and then receives an open dedicated broadcast channel for an outgoing communication, which can include a direct group communication stream to a communication server that receives and creates a group communication to all wireless telecommunication devices of the designated group. The wireless telecommunication devices selectively receives a broadcast channel based upon a predetermined probability, and assigns a greater probability of receiving an open broadcast channel for requests to transmit direct group communication streams than for requests open a broadcast channel that are not for a direct group communication.

摘要： In an embodiment, if service on both first and second networks is available, an access terminal negotiates with an access network to establish a paging cycle for the first network (e.g., 1x EV-DO) and a first dynamic paging cycle for the second network (e.g., CDMA2000 1x). If service on the second network is maintained but service on the first network becomes unavailable, the access network negotiates a second dynamic paging cycle (e.g., more aggressive or shorter than the first dynamic paging cycle) for the second network. If the access terminal determines that service on the second network is maintained and service is again available on the first network, the access terminal re-negotiates the first dynamic paging cycle for the second network. Accordingly, paging cycles on the second network are dynamically adjusted based on a service availability status of the first network.

摘要： A system and method for optimizing call setup latency for geographically dense groups including updating client location information using at least one application server while the client moves from one sector to another to provide a location update; identifying and updating parameters including location update information uniquely identifying a sector from which a client is receiving communication service; and determining at least one geographically dense call group; and choosing at least one designated responder to the at least call group. A client per cluster is selected as a designated responder for that cluster and when the server needs to set up a geographically dense group call, a random number is included corresponding to the designated responder for that group in a call setup message.
