Abstract
Methods and apparatuses are provided that prevent a user equipment (UE) from entering into a permanent out of service (OOS) state. The UE receives a registration reject message associated with a permanent cause when the UE triggers a registration request for registering with a first network entity. It is determined whether the UE was previously registered with a second network entity upon receiving the registration reject message associated with the permanent cause. The UE stores a network entity identifier of the first network entity in a temporary forbidden list when the UE was previously registered with the second network entity, to prevent the UE from entering into the permanent OOS state.
Claims14
A method of preventing a user equipment (UE) from entering into a permanent out of service (OOS) state, the method comprising:
- triggering a registration request for registering the UE with a first network entity;
- receiving, at the UE, a registration reject message associated with a permanent cause from the first network entity;
- determining whether the UE was previously registered with at least one second network entity belonging to a same country as the first network entity, upon receiving the registration reject message associated with the permanent cause;
- and
- storing, at the UE, a network entity identifier of the first network entity in a temporary forbidden list in response to determining that the UE was previously registered with the at least one second network entity belonging to the same country as the first network entity, to prevent the UE from entering into the permanent OOS state,
- wherein the UE is in communication with the first network entity and the at least one second network entity.
A user equipment (UE) configured to avoid a permanent out of service (OOS) state, the UE comprising:
- a processor;
- and
- a memory for storing computer-executable instructions that configures the processor to:
- trigger a registration request for registering with a first network entity;
- receive a registration reject message associated with a permanent cause from the first network entity;
- determine whether the UE was previously registered with at least one second network entity belonging to a same country as the first network entity, upon receiving the registration reject message associated with the permanent cause;
- and
- store a network entity identifier of the first network entity in a temporary forbidden list in response to determining that the UE was previously registered with the at least one second network entity belonging to the same country as the first network entity, to prevent the UE from entering into the permanent OOS state,
- wherein the UE is in communication with the first network entity and the at least one second network entity.
