Abstract
A method and device for transmitting a sequence of messages from a handheld telecommunications device to a telecommunications network is described, the sequence of messages comprising a plurality of messages to be transmitted at specified times. The method comprises transmitting a message of the sequence of messages and turning off at least one of the transmitter and receiver of the device after transmission of at least one of the messages in the sequence of messages. The method has particular application to messages that terminate a radio connection, such as RRC Connection Release Complete messages in a UMTS system.

A method of transmitting a sequence of Radio Resource Control Connection Release Complete messages from a wireless telecommunications device to a telecommunications network to terminate a radio connection between the device and the network, the sequence of Radio Resource Control Connection Release Complete messages comprising a plurality of Radio Resource Control Connection Release Complete messages to be transmitted at specified times, the method comprising:
- transmitting a Radio Resource Control Connection Release Complete message in a sequence of Radio Resource Control Connection Release complete messages from a wireless telecommunications device to a telecommunications network to terminate a radio connection between the device and the network;
- starting a timer, the timer having an expiry period that determines when the next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages is to be transmitted;
- on expiry of the timer, transmitting a next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, and
- when transmitting the final Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, turning off at least one of the transmitter and receiver of the device before expiration of the expiry period of the timer.
A wireless telecommunications device arranged to transmit a sequence of Radio Resource Control Connection Release Complete messages to a telecommunications network to terminate a radio connection between the device and the network, the sequence of Radio Resource Control Connection Release Complete messages comprising a plurality of Radio Resource Control Connection Release Complete messages to be transmitted at specified times, the device operatively configured to:
- transmit a Radio Resource Control Connection Release Complete message of the sequence of Radio Resource Control Connection Release Complete messages to terminate a radio connection between the device and the network;
- start a timer, the timer having an expiry period that determines when the next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages is to be transmitted;
- on expiry of the timer, transmit a next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, and
- when transmitting the final Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, turning off at least one of the transmitter and receiver of the device before expiration of the expiry period of the timer.
A non-transitory computer readable medium configured to store instructions which are executed by a processor of a wireless communications device and cause the wireless communications device to:
- transmit a Radio Resource Control Connection Release Complete message in a sequence of Radio Resource Control Connection Release complete messages from a wireless telecommunications device to a telecommunications network to terminate a radio connection between the device and the network;
- start a timer, the timer having an expiry period that determines when the next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages is to be transmitted;
- on expiry of the timer, transmit a next Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, and
- when transmitting the final Radio Resource Control Connection Release Complete message in the sequence of Radio Resource Control Connection Release Complete messages, turning off at least one of the transmitter and receiver of the device before expiration of the expiry period of the timer.
