Abstract: Methods and apparatus for expeditiously releasing network resources for a mobile station based on low battery and lost signal conditions are disclosed. The wireless network (104) receives a power down warning message from the mobile station (102) indicative of a low battery condition. The wireless network (104) then identifies whether a lost signal condition exists with the mobile station (102). In response to receiving the power down warning message and subsequently identifying the lost signal condition, the wireless network (104) causes network resources for the mobile station to be released. The wireless network (104) infers that the mobile station (102) has powered down due to low battery without enough time to send a power down registration to the wireless network (104).

Abstract: Systems and methods are provided for a cellular network to receive and decode access probes. A wireless device transmits an access probe spread with a PN code to a cellular network. The transceiver to which the wireless device is associated with can receive and decode the access probe. Additionally, other transceivers can receive and decode the access probe. In some implementations, each transceiver listens for access probes spread with their respective transceiver-specific PN code or other PN codes associated with neighbouring transceivers. In other implementations, each transceiver listens for access probes spread with a common access code. There may be more than one common access code in which each transceiver listens for access probes spread with any one of the common access codes.

Abstract: In one illustrative example, a mobile station includes a wireless transceiver; a user interface including a Push-To-Talk (PTT) switch for initiating a PTT voice communication and a microphone for receiving voice input signals; one or more processors; and a First-In-First-Out (FIFO) buffer memory coupled to the one or more processors. The one or more processors are operative to identify a user actuation of the PTT switch and, in response, save digital voice data corresponding to voice input signals in the FIFO buffer memory; cause a request for the PTT voice communication to be made through a wireless network; identify that a floor grant has been received through the wireless network in response to the request; and after identifying the floor grant, cause the digital voice data from the FIFO buffer memory to be retrieved and transmitted to the wireless network for the PTT voice communication. Advantageously, the saving of the digital voice data in the FIFO buffer memory is performed at least in part during a delay time period between the user actuation of the PTT switch and the identifying of the floor grant.

Abstract: According to the embodiments of the techniques of this application, a wireless data device or other data node sends solicitation messages periodically to a wireless gateway, such as a PDSN, when there is no data traffic between the wireless data device and a wireless data network. Each solicitation message resets the simple IP inactivity timer on the wireless gateway. When multiple wireless data devices send solicitation messages, the interval between subsequent transmissions of solicitation messages is randomised to reduce the probability of collision with the solicitations from other devices on the same wireless link. The solicitation timer, for instance, may be based on the simple IP inactivity timer setting on the wireless network, and the number of wireless data devices that the wireless data network serves. Expiration of the solicitation timer at the wireless data device or other data node causes the next solicitation message to be sent from or on behalf of the wireless data device.

Abstract translation: 根据本申请的技术的实施例，当无线数据设备和无线数据网络之间没有数据业务时，无线数据设备或其他数据节点周期性地向无线网关（例如PDSN）发送请求消息。 每个请求消息复位无线网关上的简单IP不活动定时器。 当多个无线数据设备发送请求消息时，随机发送请求消息的后续传输间隔，以减少与同一无线链路上的其他设备的请求相冲突的概率。 例如，请求定时器可以基于无线网络上的简单IP不活动定时器设置，以及无线数据网络服务的无线数据设备的数量。 在无线数据设备或其他数据节点处的请求定时器的到期导致下一个请求消息从无线数据设备或代表无线数据设备发送。
