Abstract: Techniques involving a wireless user device adapted to operate in a carrier network, and associated with a private organization having a private communication network which is not part of the carrier network, are described. The wireless user device gains wireless access via the carrier network and communicates, via the carrier network, with other wireless user devices in a push-to-talk (PTT) voice communication session. The PTT voice communication session is delivered via a carrier processing element of the carrier network, where voice communications of the PTT voice communication session are routed and processed through a private processing element of the private communication network. The voice communications from the wireless user device are assigned and communicated with a generic identifier of the private organization instead of a user identifier of the wireless user device.

Abstract: In one illustrative example of the present application, a mobile communication device has one or more processors, a wireless transceiver adapted to provide communications through a wireless communication network, and a buffer memory for use in buffering a Push-To-Talk (PTT) communication from the mobile communication device. The one or more processors are operative to produce a mobile device indication message which indicates the mobile device's support for buffering of the PTT communication. This message is transmitted by the wireless transceiver to a PTT service entity through the wireless network. The one or more processors may be further operative to receive, from the PTT service entity through the wireless network, a network indication message which instructs the mobile device whether to use buffering for the PTT communication. The mobile device may use the buffer memory for the buffering of the PTT communication based on the network indication message from the PTT service entity.

Abstract: A method of determining the actual transmission rate in a variable transmission rate communication system is provided, using error detection metrics. The received symbols are decoded assuming each possible rate, and then re-encoded to determine a symbol error rate for each possible rate. The possible transmission rates are then narrowed down using a simple measure of the likelihood of error, such as the CRC status determined for each rate. The symbol error rates are compared to either make a confident decision as to the actual transmission rate or to erase the frame. Rather than compare the values of the symbol error rates with predetermined thresholds, the method compares the differences between the symbol error rates for each possible rate with predetermined thresholds. This results in fewer erasures, even if the symbol error rates are low due to high signal to noise ratios.

Abstract: A method is performed by a wireless device. The method includes (a) preselecting a set of the base stations; (b) selecting a reverse link cost according to a preselected reverse link cost metric; (c) selecting a base station from the set of base stations; and (d) sending a probe signal at the selected reverse link cost to the selected base station. If a response is not received from the selected base station within a preselected time period and not all the base stations have been sent a probe signal at substantially the selected reverse link cost, then steps (c) through (d) are repeated with a different one of the base stations at substantially the selected reverse link cost. If a response is received from the selected base station within the timeout period, then the responding base station is selected to provide access to the wireless network.
