Abstract
A user equipment (UE) avoids entering a limited service state when the UE attempts to switch from a first radio access technology (RAT) to a second RAT when the UE experiences a communication service outage with respect to the second RAT. In one instance, the UE attempts to access the second radio access technology (RAT) from a first RAT. The first RAT may be in a service outage or have weak coverage. The UE does not reach a maximum number of network access failures in the second RAT. Rather, the UE attempts to acquire a third RAT before reaching the maximum number of retries. The third RAT may be the same as the first RAT or may be a different RAT altogether.
Claims30
A method of wireless communication, comprising:
- currently attempting, by a user equipment (UE), to access a second radio access technology (RAT) from a first RAT;
- and
- preventing the UE from reaching a maximum number of network access failures in the second RAT by attempting to acquire a different RAT.
An apparatus for wireless communication, comprising:
- means for currently attempting to access a second radio access technology (RAT) from a first RAT;
- and
- means for preventing a user equipment (UE) from reaching a maximum number of network access failures in the second RAT by attempting to acquire a different RAT.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured:
- to currently attempt to access a second radio access technology (RAT) from a first RAT;
- and
- to prevent a user equipment (UE) from reaching a maximum number of network access failures in the second RAT by attempting to acquire a different RAT.
A computer program product for wireless communication, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to currently attempt to access a second radio access technology (RAT) from a first RAT;
- and
- program code to prevent a user equipment (UE) from reaching a maximum number of network access failures in the second RAT by attempting to acquire a different RAT.
