Abstract
A method of performing a Radio Resource Control, RRC, connection establishment in accordance with a cell selection process, wherein a first timer is used to controlling that the cell selection process is performed within a first time, and a second timer is used to controlling that a cell is treated as barred for a second time if certain system information associated to that cell is missing or cannot be acquired, and controlling the first timer and the second timer such that the second timer expires in a time period after the first timer has been started and before the first timer has expired. The invention further refers to a User Equipment (UE) that performs the method and a computer program loadable into the UE.
Claims14
A method, in a user equipment (UE), for performing Radio Resource Control (RRC) connection establishment, the method comprising:
- performing cell selection in accordance with a cell selection process, wherein a first timer is used to control that the cell selection process is performed within a first time, and a second timer is used to control that a cell is treated as barred for a second time if certain system information associated to that cell is missing or cannot be acquired;
- and
- controlling the first timer and the second timer such that the second timer expires in a time period after the first timer has been started and before the first timer has expired,
- wherein controlling the second timer comprises modifying the second timer, and
- wherein modifying the second timer comprises setting the second timer to a predefined connected mode second value before starting the second timer.
A user equipment adapted to perform a Radio Resource Control (RRC) connection establishment procedure, the user equipment comprising:
- a first timer configured to control that a selection of a cell is performed within a first time;
- a second timer configured to control that the cell is regarded as being barred if certain system information associated to that cell cannot be acquired;
- a processing circuit configured to perform cell selection in accordance with a cell selection process and based on the first and second timers;
- a timer controller circuit configured to control the first timer and the second timer such that the second timer expires after the first timer has been started and before the first timer has expired,
- wherein the timer controller circuit is further configured to modify the second timer and to set the second timer to a predefined connected mode second value before starting the second timer.
A computer program product stored in a non-transitory computer readable medium for controlling performance of Radio Resource Control (RRC) connection establishment by a user equipment, the computer program product comprising software instructions which, when run on one or more processing circuits of the user equipment, causes the user equipment to:
- perform a cell selection in accordance with a cell selection process, wherein a first timer is used to control that the cell selection process is performed within a first time, and a second timer is used to control that a cell is treated as barred for a second time if certain system information associated to that cell is missing or cannot be acquired;
- control the first timer and the second timer such that the second timer expires in a time period after the first timer has been started and before the first timer has expired wherein the user equipment is further configured to modify the second timer and to,
- set the second timer to a predefined connected mode second value before starting the second timer.
