A wireless communication terminal and a corresponding method therein includes initiating a first radio link control reset procedure, and receiving a message after initiating the first radio link control reset procedure and before the first radio link reset procedure is complete, wherein the message contains an instruction to set a protocol data unit size. A second radio link control reset procedure is initiated after setting the protocol data unit size.

Establishing radio link control in wireless communication networks

A wireless communication terminal () including a radio transceiver (), and a radio link control entity () that re-initiates a radio link control reset procedure when the transceiver receives a message containing an instruction to change an uplink or downlink protocol data unit size during an ongoing radio link control reset procedure. For example, the radio access network may initiate an uplink or downlink PDU size change before terminal receives acknowledgement that a previously initiated radio link control reset procedure is complete. The radio link control entity restarts a radio link control reset timer upon re-initiating the radio link control reset procedure after re-establishing radio link control.

A method and apparatus for reducing access delay in push-to-talk (PTT) over Cellular (PoC) communication sessions is provided in a wireless communication device () including a quality level controller () which controls the quality level at which the transmit talkburst controller () provides talkbursts to transmitter circuitry (). A processor () signals the quality level controller () and the transmit talkburst controller () to provide a first talkburst to the transmitter circuitry () for transmitting at a first quality level (), and thereafter signals the quality level controller () to adjust the quality level from the first quality level to a second quality level () so that the transmit talkburst controller () will provide at least one subsequent talkburst to the transmitter circuitry () for transmitting at the second quality level ().

While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel (). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel (), and the UE is placed in idle mode (). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.

A multi-mode mobile wireless communications device architecture () including an application layer (), a services layer () interfacing the applications layer, a multi-mode layer () interfacing the service layer, and a hardware layer () interfacing the multi-mode layer. The multi-mode layer includes first and second interoperable radio access technologies, for example W-CDMA UMTS and GSM/GPRS technologies.
