Abstract

The present application relates to the technical field of communication, and in particular to the network selection technology of a terminal. The network selection method of the terminal in the present disclosure includes: acquiring an equivalent public land mobile network (EPLMN) list; determining whether the EPLMN in the EPLMN list supports the first access technology; when determining that the EPLMN does not support the first access technology, When the first access technology is used, prevent access to the EPLMN by using the first access technology.

Claims

A method for network access, the method comprising:

acquiring an Equivalent Public Land Mobile Network (EPLMN) list;

determining whether an EPLMN in the EPLMN list supports a first access technology;

and when the EPLMN is determined not to support the first access technology, preventing access to the EPLMN by the first access technology.
The method of claim 1, wherein the method further comprises:

accessing the EPLMN using a second access technology supported by the EPLMN, the second access technology being different from the first access technology.
The method of claim 1 or 2, wherein the preventing access to the EPLMN using the first access technology comprises:

preventing delivery of the EPLMN to an Access Stratum (AS) supporting the first access technology.
The method of any of claims 1 to 3, wherein the first access technology is a Long Term Evolution (LTE) access technology.
A method according to any one of claims 1 to 4, wherein the determining whether the EPLMNs in the EPLMN list support a first access technology comprises:

querying a stored extended EPLMN list based on an identification of an EPLMN in the EPLMN list, wherein the extended EPLMN list includes, for each EPLMN, information indicating whether the first access technology is supported by the EPLMN;

and judging whether the EPLMN supports the first access technology or not according to the query result.
A terminal, characterized in that the terminal comprises:

a memory configured to store program codes and data for the processor to perform operations;

a processor configured to: acquiring an Equivalent Public Land Mobile Network (EPLMN) list; determining whether an EPLMN in the EPLMN list supports a first access technology; and when the EPLMN is determined not to support the first access technology, preventing access to the EPLMN by the first access technology.
The terminal of claim 6, wherein the processor is further configured to access the EPLMN using a second access technology supported by the EPLMN, the second access technology different from the first access technology.
The terminal of claim 6 or 7, wherein the processor is configured to prevent delivery of the EPLMN to an Access Stratum (AS) that supports the first access technology.
The terminal of any of claims 6 to 8, wherein the first access technology is a Long Term Evolution (LTE) access technology.
A terminal as claimed in any one of claims 6 to 9, wherein the processor is configured to query a stored extended EPLMN list in dependence on the identity of the EPLMNs in the EPLMN list, wherein the extended EPLMN list includes for each EPLMN information indicating whether the first access technology is supported by the EPLMN; and judging whether the EPLMN supports the first access technology or not according to the query result.
