Example 1

The embodiment of the present invention describes a method for identifying an overlapping spectrum of a terminal. First, a file containing a working frequency band supported by one or more PLMN IDs is pre-stored in the terminal, and the content is a PLMN ID of the operator in the cell network (a The PLMN ID of the operator in the cell network is generally one, but may also be multiple) and the working frequency band of the overlapping spectrum supported by the operator. Table 4 is the working frequency band supported by multiple PLMN IDs in the first embodiment of the present invention. Indicate. The terminal can search for the operator (ie, the searched cell) by reading the public land mobile network code of the searched cell network, that is, the PLMN ID, by storing the file containing the working frequency band supported by one or more PLMN IDs. The working frequency band supported by the network, the terminal determines whether to access the searched cell network according to the working frequency band supported by the searched cell network.

PLMN ID Band 44020 Band V 44010 Band VI

Table 4

This embodiment assumes that the terminal is a terminal that supports Band 1, Band V, and Band VIII. FIG. 3 is a flowchart of a first embodiment of a method for implementing network registration according to the present invention. As shown in FIG. 1 , the steps for a terminal to perform network registration to implement an access network include:

Step 300: The terminal searches for a cell network; here, it is assumed that the currently searched cell network is a network of overlapping frequency bands, for example, a cell network with a downlink frequency of 880 MHz is searched, and according to Table 3, the Band V belongs to the Band VI and overlaps. The working frequency band of the spectrum;

Step 301: The terminal reads the PLMN ID of the currently searched cell network. The assumption is "44010".

Step 302: The terminal queries the working frequency band supported by one or more PLMN IDs stored in advance according to the obtained PLMN ID, and obtains the working frequency band currently supported by the cell network. Here, the working frequency band currently supported by the cell network is BandVI.

Step 303: When the working frequency band of the currently searched cell network does not include the frequency band supported by the terminal, the terminal searches for a new cell network.

Here, since the terminal is a terminal that supports Band 1, Band V and Band VIII. The working frequency band of the currently searched cell network is BandVI. Therefore, the working frequency band of the currently searched cell network does not include the frequency band supported by the terminal.

It should be noted that, when the new cell network is re-searched in this embodiment, if the PLMN ID of the re-searched cell network is “44020”, the working frequency band of the re-searched cell network is BandV. In this embodiment, the terminal is up to the cell network in which the frequency band is BandV, so the cell network is registered to access the cell network.
