Abstract
A method includes, in a mobile communication terminal configured to operate in a manual network registration mode, maintaining in a memory a list of one or more Equivalent Public Land Mobile Networks (EPLMNs) with which the terminal is permitted to register. Upon registering with a Public Land Mobile Network (PLMN), the one or more EPLMNs already on the list are retained, and, if receiving from the PLMN a notification of at least one EPLMN defined for the PLMN, the at least one EPLMN is added to the list. In response to loss of communication with the PLMN, registration is performed with a selected EPLMN among the EPLMNs appearing on the list.

A method, comprising:
- in a mobile communication terminal configured to operate in a manual network registration mode, maintaining in a memory a list of one or more Equivalent Public Land Mobile Networks (EPLMNs) with which the terminal is permitted to register;
- upon registering with a Public Land Mobile Network (PLMN), retaining the one or more EPLMNs already on the list, and, if receiving from the PLMN a notification of at least one EPLMN defined for the PLMN, adding the at least one EPLMN to the list;
- and
- in response to loss of communication with the PLMN, registering with a selected EPLMN among the EPLMNs appearing on the list.
Apparatus, comprising:
- a memory;
- and
- processing circuitry, which is configured, when operating in a manual network registration mode, to store in the memory a list of one or more Equivalent Public Land Mobile Networks (EPLMNs) with which the apparatus is permitted to register, to retain the one or more EPLMNs already on the list upon registering with a Public Land Mobile Network (PLMN), and, if receiving from the PLMN a notification of at least one EPLMN defined for the PLMN, to add the at least one EPLMN to the list, and, in response to loss of communication with the PLMN, to register with a selected EPLMN among the EPLMNs appearing on the list.
