The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of Embodiment 1 of a reporting method of a PLMN according to the present invention. Referring to FIG. 1, the embodiment includes the following steps:

Step 100: The user equipment located in the coverage of the macro cell measures the neighboring cell of the macro cell, and obtains the public land mobile network identifier PLMN ID of the CSG cell of the closed subscription group.

Specifically, the user equipment located in the coverage of the macro cell receives the frequency information of the adjacent CSG cell of the macro cell broadcasted by the macro cell, and when one macro cell is adjacent to multiple CSG cells, the frequency of each CSG cell at this time The point information is different. Therefore, the user equipment measures each CSG cell according to the frequency point information corresponding to each CSG cell, and obtains the PLMN ID corresponding to each CSG cell.

Step 101: The user equipment acquires, according to the local whitelist and the PLMN ID, a PLMN that is allowed to be accessed by the user equipment of the CSG cell.

Specifically, before the user equipment performs measurement on the CSG cell, the user equipment has obtained a local white list, and the local white list includes a PLMN that allows the user equipment to access. Step 102: When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN and/or the registered PLMN, the user equipment determines the first PLMN ID of the CSG cell according to the home PLMN and/or the registered PLMN.

It should be noted that the user equipment itself can identify the corresponding home PLMN, the registered PLMN, and the equivalent PLMN. The user equipment obtains the PLMN ID corresponding to each CSG cell and the PLMN that allows the user equipment to access in the local whitelist. The user equipment determines to obtain the home PLMN or the registered PLMN in the PLMN ID corresponding to each CSG cell. And the PLMN ID of the home PLMN and/or the registered PLMN is the first PLMN ID.

Step 103: The user equipment carries the first PLMN ID of the CSG cell and the first indication information that is used to indicate that the PLMN corresponding to the first PLMN ID is the home PLMN or the registered PLMN, in the measurement information.

Specifically, the first indication information may be specifically implemented by adding a corresponding indicator bit to the first PLMN ID in the measurement information, and indicating that the PLMN corresponding to the carried PLMN ID is the home PLMN or the registered PLMN by using indication information with different indication bits. For example, a new 2-bit indicator bit is added to the first PLMN ID in the measurement information. When the indication information is 01, the corresponding first PLMN ID is the home PLMN. When the indication information is 10, the first PLMN ID is corresponding. To register a PLMN. Moreover, when multiple CSG cells are deployed in the macro cell, since the user equipment measures each CSG cell, the reported measurement information needs to include the identification information of each CSG cell. Therefore, when there is a home PLMN or a registered PLMN in a CSG cell, the macro cell accesses the CSG cell by using the identity information of the CSG cell and selects the home PLMN or the registered PLMN as the PLMN for carrying the service.

Step 104: The user equipment reports the measurement information to the network side device to which the macro cell belongs.

Specifically, after the user equipment determines that the home PLMN or the registered PLMN in the PLMN ID corresponding to each CSG cell is obtained, the user equipment reports the measurement information to the network side device to which the macro cell belongs, so that the network side device is the user according to the first indication information. The device selects the PLMN used to carry the service. It should be noted that when the macro cell deploys multiple CSG cells, the user equipment reports the measurement information to the network side device to which the macro cell belongs for each CSG cell.

The reporting method of the PLMN provided in this embodiment is to measure the neighboring cell of the macro cell by using the user equipment located in the coverage of the macro cell, and obtain the public land mobile network identifier of the CSG cell. The PLMN ID is obtained by the user equipment, according to the local whitelist and the PLMN ID, the PLMN of the CSG cell that is allowed to access by the user equipment. When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN and/or the registered PLMN, the user equipment Determining, by the home PLMN and/or the registered PLMN, the first PLMN ID of the CSG cell, the first PLMN ID of the CSG cell, and the first indication information that is used to indicate that the PLMN corresponding to the first PLMN ID is the home PLMN or the registered PLMN The measurement information is carried in the measurement information, and finally the user equipment reports the measurement information to the network side device to which the macro cell belongs, so that the network side preferentially accesses the user equipment to the home PLMN or the registered PLMN with lower tariff.

Further, when the macro cell is a GERAN cell and the CSG cell is a shared cell, the step 102 of the first method for reporting the PLMN is specifically as follows:

When the PLMN of the CSG cell that is allowed to access the user equipment includes the home PLMN and the registered PLMN, determining that the PLMN ID corresponding to the home PLMN is the first PLMN ID of the CSG cell; or

When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN or the registered PLMN, it is determined that the PLMN ID corresponding to the home PLMN or the registered PLMN is the first PLMN ID of the CSG cell.

Specifically, when the macro cell is a GERAN cell, the length of the measurement information reported by the user equipment to the GERAN cell is limited, so there is not enough space in the measurement information to carry two or more PLMN IDs. When the CSG cell is a shared cell, that is, when the CSG cell shares multiple PLMNs, if the user equipment identifies that there is a home PLMN or a registered PLMN among multiple PLMN IDs corresponding to the CSG cell, the home PLMN or the registered PLMN will be preferentially selected. The first PLMN ID is set in the measurement information, and the first indication information indicating that the PLMN corresponding to the carried first PLMN ID is the home PLMN or the registered PLMN is simultaneously set in step 103 of the first embodiment of the PLMN. In the measurement information. In this way, when the macro cell receives the corresponding measurement information of the multiple CSG cells reported by the user equipment, the user equipment may be accessed according to the first indication information to the CSG cell having the user equipment corresponding to the home PLMN or the registered PLMN, and the selected The home PLMN or the registered PLMN acts as a PLMN for carrying services.

When the macro cell is a GERAN cell and the CSG cell is a non-shared cell, the step 102 of the first method of reporting the PLMN is specifically as follows: When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN or the registered PLMN, it is determined that the PLMN ID corresponding to the home PLMN or the registered PLMN is the first PLMN ID of the CSG cell.

Specifically, the measurement information reported by the user equipment to the macro cell of the GERAN cell can only include one PLMN ID. When the CSG cell measured by the user equipment is a non-shared cell, the CSG cell only corresponds to one PLMN. At this time, the user equipment determines, according to the local whitelist, that the PLMN corresponding to one PLMN ID of the CSG cell allows the user equipment to access, and the user equipment recognizes that the first PLMN is the home PLMN or the registered PLMN of the user equipment, The first PLMN ID of the home PLMN or the registered PLMN is set in the measurement information. When the macro cell receives the measurement information corresponding to the multiple CSG cells reported by the user equipment, the user equipment may be accessed according to the first indication information to the CSG cell that has the user equipment corresponding to the home PLMN or the registered PLMN, and select the home PLMN. Or register the PLMN as a PLMN for carrying services.

When the macro cell is a GERAN cell, optionally, the measurement information reported by the user equipment to the CSG cell may be a Measurement Report or an Enhanced Measurement Report, as shown below, and the measurement information is in the macro cell. Specific embodiments when the GERAN cell and the CSG cell are UTRAN cells:

< UTRAN CSG Measurement Report IE >:: =

< UTRAN CI: bit (28) >

{ 0 I 1 < PLMN-ID: < PLMN-ID struct > > }

< CSG-ID: bit (27) >

< Access Mode: bit (1) >

< REPORTING— QUANTITY: bit (6) >;

<PLMN indicator bit(2)

The UTRAN CI is the ID of the UTRAN CSG cell, and the PLMN indicator is the PLMN indicator bit. Optionally, when the PLMN indicator is 01, the indicated PLMN ID is the first PLMN ID, and the first PLMN ID is the home PLMN; When the indicated PLMN ID is the first PLMN ID, and the first PLMN ID is the registered PLMN; when it is 00, it indicates that the indicated PLMN ID is neither the home PLMN nor the registered PLMN. When the CSG cell is an E-UTRAN cell, the situation is similar, and details are not described herein again. When the macro cell is a UTRAN or an E-UTRAN cell, and the CSG cell is a shared cell, the step 102 of the first embodiment of the PLMN may be specifically as follows:

Step 102a: When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN and the registered PLMN, determine that the PLMN ID corresponding to the home PLMN is the first PLMN ID of the CSG cell.

Specifically, in a shared CSG cell, when there is a home PLMN and a registered PLMN, since the home PLMN has a lower tariff for the user equipment, it is preferable to determine that the PLMN ID corresponding to the home PLMN is the first PLMN of the CSG cell. ID.

Step 102b: When the PLMN of the CSG cell that allows the user equipment to access includes the home PLMN and the registered PLMN, determine that the PLMN ID corresponding to the home PLMN is the first PLMN ID of the CSG cell, and determine that the PLMN ID corresponding to the registered PLMN is the CSG cell. Second PLMN ID.

Specifically, after determining that the PLMN ID corresponding to the registered PLMN is the second PLMN ID of the CSG cell, the second indication information that is used to indicate that the PLMN corresponding to the second PLMN ID is the registered PLMN is set in the measurement information, and may pass The indication bit indicates the second PLMN ID, for example, the indication bit is 00, indicating that the indicated second PLMN ID is the registered PLMN. It should be noted that the indicator bit is not specifically limited as long as it can be distinguished from the first indication information.

Step 102c: When the PLMN of the CSG cell that allows the user equipment to access only includes the home PLMN or the registered PLMN, determine that the PLMN ID corresponding to the home PLMN or the registered PLMN is the first PLMN ID.

Specifically, the user equipment determines, according to the local white list, a PLMN of the CSG cell.

The PLMN corresponding to the ID allows the user equipment to access, and the user equipment identifies that the PLMN is the home PLMN or the registered PLMN of the user equipment, and determines that the PLMN ID corresponding to the home PLMN or the registered PLMN is the first PLMN ID, and the first PLMN ID is set. In the measurement information, and in the step 103 of the first embodiment of the reporting method of the PLMN, the first indication information indicating that the PLMN corresponding to the carried first PLMN ID is the home PLMN or the registered PLMN is set in the measurement information. The macro cell selects the home PLMN or the registered PLMN as the PLMN for carrying the service for the user equipment according to the first indication information.

For the above three cases, specifically, when the macro cell is a UTRAN or E-UTRAN cell, the measurement information reported by the user equipment to the macro cell does not limit the number of PLMN IDs. So use The user equipment may carry all the PLMN IDs corresponding to the PLMNs of the CSG cell that are allowed to access the user equipment in the measurement information, and set the first indication information indicating that the PLMN corresponding to the first PLMN ID is the home PLMN or the registration PLMN. In the measurement information.

When the CSG cell that is measured by the user equipment is a shared cell, the user equipment acquires the PLMN that allows the user equipment to access in the multiple PLMN IDs corresponding to the CSG cell according to the local whitelist, and the user equipment identifies the home PLMN and/or the registered PLMN. After determining the home PLMN and/or the registered PLMN of the user equipment, the first PLMN ID of the home PLMN or the registered PLMN, and the PLMN ID corresponding to all PLMNs of the CSG cell that are allowed to access by the user equipment are set in the measurement information, In the case of the step 102b, the PLMN ID corresponding to the registered PLMN, that is, the second PLMN ID, may be set in the measurement information and reported to the network side device of the macro cell. When the network side device to which the macro cell belongs receives the corresponding measurement information of the multiple CSG cells reported by the user equipment, the user equipment may be accessed according to the first indication information to the CSG cell with the user equipment corresponding to the home PLMN or the registered PLMN. And the home PLMN or the registered PLMN is selected as the PLMN for carrying the service.

For the case where the macro cell is a UTRAN or an E-UTRAN cell, and the CSG cell to be measured is a non-shared cell, the step 102 of the first method of reporting the PLMN is specifically as follows:

When the PLMN of the CSG cell that allows the user equipment to access only includes the home PLMN or the registered PLMN, it is determined that the PLMN ID corresponding to the home PLMN or the registered PLMN is the first PLMN ID.

Specifically, when the measured CSG cell is a non-shared cell, that is, the CSG cell corresponds to only one PLMN, which is similar to the foregoing step 102c, and details are not described herein again.

It should be noted that the local whitelist may not include corresponding information indicating the home PLMN or the registered PLMN, and the user equipment may directly identify the PLMN that allows the user equipment to access, and determine the home PLMN or the registered PLMN; Includes corresponding information indicating the home PLMN or the registered PLMN. In addition, for the CURAN or the E-UTRAN cell, the user equipment may report the PLMN ID corresponding to each CSG cell to the macro cell by using one piece of measurement information, or may be directed to the macro cell. Each CSG cell reports a measurement information. This is not limited.

When the macro cell is a UTRAN or an E-UTRAN cell, the measurement information reported by the user equipment to the CSG cell may be a measurement report, as shown below. Specific embodiments of the amount information when the macro cell is a UTRAN or E-UTRAN cell and the CSG cell is a UTRAN cell:
