A method and apparatus for a device in which when an attempt on a frequency to camp on a cell fails, there is an indication stored in relation to the frequency of the failed camping attempt.

Automatic tracking of mobile device camping failure to an access point

A method at a user equipment for establishing a circuit switched call, the user equipment being in a Cell Forward Access CHannel (CELL_FACH) state, a Cell Paging CHannel (CELL_PCH) state or a UTRAN Registration Area Paging CHannel (URA_PCH) state, the method receiving an indication that a circuit switched call is pending; sending to a network element a message to facilitate the user equipment to transition to a Cell Dedicated CHannel (CELL_DCH) state, the message being one of a cell update message having a traffic volume indicator information element indicating that pending uplink data exceeds a threshold or an RRCConnectionRequest message; and establishing the circuit switched call.

Method and system for voice call setup from a PCH or FACH state

A system and method for addressing RLC unrecoverable errors experienced by User Equipment (UE) in a wireless network help the network to resolve the errors without shifting the UE into an Idle mode and dropping voice calls. A measurement event provides the buffer occupancy and identifies the affected radio bearer to the network. If the state of the bearer is not changed, the UE provides a Signaling Connection Release Indication message or a Radio Bearer Release Indication message to the network, the latter message identifying the radio bearer to be released without taking down the entire signaling connection for the domain.

Method and apparatus for radio resource control procedures

A user equipment and a method performed by the user equipment is provided. The method comprises receiving a network message from a network, inhibiting a sending of a user equipment message to the network and transitioning to a target state. The user equipment is adaptable/adapted and/or configurable/configured to receive a network message from a network, inhibit a sending of a user equipment message to the network and transition to a target state. The network message indicates the target state to which the user equipment is to transition.

System and method of user equipment state transition

Apparatus and a method for sending measurement report messages from a wireless telecommunications device to a wireless telecommunications network are disclosed. The method comprises at the wireless telecommunications device: generating a measurement report in respect of a first event; transmitting a first message including the measurement report in respect of the first event to the network; generating a subsequent measurement report for another event; determining whether conditions for the first event are still satisfied and, if so, including in a subsequent message the measurement report for the first event as well as the measurement report for the other event; and transmitting the subsequent message to the network.
