Abstract
A User Equipment (UE) includes a controller. The controller is in automatic network selection mode, and the controller stops a Tsor-cm timer in a case that the controller switched to manual network selection mode and the Tsor-cm timer is running.
Claims2
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- and
- a controller,
- wherein
- the transmission and reception circuitry is configured to receive a Non-Access-Stratum (NAS) message including Steering of roaming connected mode control information (SOR-CMCI),
- the SOR-CMCI includes a plurality of criteria and a plurality of timer values,
- the plurality of criteria includes a first criterion and a second criterion,
- the plurality of timer values includes a first timer value and a second timer value,
- the first timer value is associated with the first criterion,
- the second timer value is associated with the second criterion,
- in a case that there are the first criterion and the second criterion applicable to a plurality of protocol data unit (PDU) sessions, the controller is configured to start a first Tsor-cm timer set to the first timer value and a second Tsor-cm timer set to the second timer value, and
- the controller is further configured to stop the first Tsor-cm timer and the second Tsor-cm timer in response to determining that the controller switches from an automatic network selection mode to a manual network selection mode while the first Tsor-cm timer and the second Tsor-cm timer are running.

A method performed by a User Equipment (UE), the method comprising:
- receiving a Non-Access-Stratum (NAS) message including Steering of roaming connected mode control information (SOR-CMCI),
- wherein
- the SOR-CMCI includes a plurality of criteria and a plurality of timer values,
- the plurality of criteria includes a first criterion and a second criterion,
- the plurality of timer values includes a first timer value and a second timer value,
- the first timer value is associated with the first criterion, and
- the second timer value is associated with the second criterion;
- in a case that there are the first criterion and the second criterion applicable to a plurality of protocol data unit (PDU) sessions, starting a first Tsor-cm timer set to the first timer value and a second Tsor-cm timer set to the second timer value;
- and
- stopping the first Tsor-cm timer and the second Tsor-cm timer in response to determining that the UE switches from an automatic network selection mode to a manual network selection mode while the first Tsor-cm timer and the second Tsor-cm timer are running.
