Abstract: A method for disaster roaming includes initiating disaster roaming search by user equipment (UE) if one of following conditions occurs: the UE receives System Information Block (SIB) from a first Public Land Mobile Network (PLMN), the UE receives a message and/or an information element from the first PLMN indicating an occurrence of a disaster or availability of disaster roaming, and the UE determines out-of-service (OOS) from the first PLMN. The SIB includes at least one disaster roaming information element. The method further includes searching by the UE for a second PLMN to register.

Abstract: Various solutions for problem cell handling with respect to user equipment in mobile communications are described. An apparatus may transmit user equipment (UE) capability information to a cell. The apparatus may determine the cell as a problem cell in response to no service received from the cell. The apparatus may reduce a size of the UE capability information. The apparatus may further transmit the reduced UE capability information to the problem cell.
