Description

Method for sending and receiving network identification information and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for sending and receiving network identification information.

Background

When a Non-Public Network (NPN) is deployed, different identification information from that of the Public Network is used. The identification information is broadcast through system information, such as a System Information Block (SIB). The NPN identification comprises: public Land Mobile Network (PLMN) identification, readable Network name (e.g., "a factory Network"). Wherein, the PLMN id of the NPN includes the following parts: mobile Country Code (MCC) and Mobile Network Code (MNC) taking values of 999.

The network side sends the PLMN identification information list (i.e. 1 or more PLMN identifications) through SIB 1 message. And the terminal judges whether the cell belongs to a network in which the cell can work by identifying the PLMN identification information.

Since the MCC value of the NPN network is "999" constant (generally 12 bits), additional signaling loss is generated when signaling to the terminal.
