Abstract: Methods and apparatus for facilitating concurrent Push-to-talk over Cellular (PoC) group communication sessions for a mobile station (102) are disclosed. A first PoC communication session (550) for a first user group (504) is maintained while a second PoC communication session (552) for a second user group (506) is concurrently maintained, where the second user group (506) has at least one common member (516) with the first user group (504). The second user group (506) may have at least one member (518, 520) which is not included in the first user group (504). Through a user interface, a PoC user may select between the first and the second user groups (504 and 506) for communication or combine the communications. In an alternative embodiment, all of the members (518, 520, 522) of a second user group (604) may be included in a first user group (602). In a specific approach, encrypted data packets of a PoC communication sub-session are communicated during a PoC communication session. If a key for the encrypted data packets is known for the mobile station (102), the encrypted data packets are decrypted to facilitate the PoC communication sub-session involving the mobile station (102); otherwise the encrypted data packets are discarded.

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: It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.
