Abstract
Provided are systems and methods for releasing a radio resource control (RRC) connection between a user equipment and a radio network controller. The system may include a user equipment and a radio network controller. The user equipment may be configured to transmit a RRC connection release indication when a timer expires in a connected mode and release the RRC connection upon receiving a RRC connection release message. The radio network controller may be configured to receive the RRC connection release indication from the user equipment and transmit the RRC connection release message in response to the RRC connection release indication.
Claims17
A system for releasing a radio resource control (RRC) connection, the system comprising:
- user equipment configured to transmit a RRC connection release indication when a timer expires in at least one of a Cell_paging channel (Cell_PCH) state and a universal mobile telecommunications system terrestrial radio access network registration area_paging channel (URA_PCH) state and release the RRC connection upon receiving a RRC connection release message;
- and
- a radio network controller configured to receive the RRC connection release indication from the user equipment and transmit the RRC connection release message in response to the RRC connection release indication.
A method of releasing a radio resource control (RRC) connection, the method comprising:
- transmitting, by user equipment, a RRC connection release indication to a radio network controller when a timer expires in at least one of a Cell_paging channel (Cell_PCH) state and a universal mobile telecommunications system terrestrial radio access network registration area_paging channel (URA_PCH) state;
- releasing the RRC connection to the radio network controller upon receiving a RRC connection release message from the radio network controller;
- and
- transitioning from the connected mode to an idle mode.
A method of a radio network controller for releasing a radio resource control (RRC) connection, the method comprising:
- receiving a Cell update message including a RRC connection release indication from user equipment, where the RRC connection release indication is transmitted from the user equipment when a timer of the user equipments expires and the user equipment is in at least one of a Cell_paging channel (Cell_PCH) state and a universal mobile telecommunications system terrestrial radio access network registration area_paging channel (URA_PCH) state;
- initiating a RRC connection release procedure for releasing the RRC connection between the user equipment and the radio network controller;
- and
- transmitting a RRC connection release message to the user equipment in response to the Cell update message.
