3GPP introduced the concept of Closed Subscriber Grou (CSG) in R8 to implement access control. The so-called CSG is a group of subscribers that are allowed to access one or more specific cells. The user equipment (User Equipment, UE) is limited when accessing the CSG cell.

In the prior art, each CSG cell may include one or more Home NodeBs (hereinafter referred to as HNBs), and each CSG cell is identified by one CSG ID, and therefore, the HNBs in each CSG cell have the same CSG ID. The HNB Management System (HNB Management System, hereinafter referred to as HMS) can manage and configure the CSG ID of the CSG cell. For example, in an enterprise network scenario, HMS can be located inside the enterprise network as a management platform for enterprise control HNB. The UE can maintain a CSG ID list, such as a list of allowed CSG IDs. Therefore, the UE can access the CSG cell in the CSG ID list.

In the actual operation of the network, the CSG ID is often modified. However, the inventor found that once the HMS modifies the CSG ID, the UE cannot access the original. This CSG cell has access to the CSG. Summary of the invention

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 a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The present invention can be applied to various communication systems, such as Wideband Code Division Multiple Access (WCDMA) system, Code Division Multiple Access (CDMA) system and long-term Evolution (Long Term Evolution, hereinafter referred to as LTE) system. FIG. 1 is a flowchart of an embodiment of an identifier update processing method according to the present invention. As shown in FIG. 1, the method in this embodiment may be as follows:

101. Receive a first CSG update request message sent by the home base station, where the first CSG update request message includes a new CSG identifier of the home base station.

For example, the home base station gateway (HNB GateWay, hereinafter referred to as HNB-GW) can receive the first CSG update request message sent by the HNB. The HNB-GW can be located in the carrier network.

Specifically, when the HMS modifies the CSG ID, the HMS may send a CSG update indication message to an HNB or multiple HNBs in the CSG cell, where the CSG update indication message may include a new CSG ID. When the HNB learns that the HMS has modified the CSG ID, the HNB may send a first CSG update request message to the HNB-GW, and the new CSG ID modified by the HMS is carried in the first CSG update request message.

It should be noted that if there is only one HNB in the CSG cell, the HNB is the HNB that sends the first CSG update request message. If the CSG cell includes multiple HNBs, the HMS may indicate that the CSG update indication message is received. One of the HNBs sends a first CSG update request message. The embodiment does not limit the specific policy of the HMS indicating which HNB of the multiple HNBs can send the first CSG update request message. For example, the HMS may indicate that the HNB with the highest security among the multiple HNBs sends the first CSG update request. The message may indicate that the HNB with the least load among the plurality of HNBs sends the first CSG update request message or the like, provided that the HNB needs to have the capability of reporting information. The embodiment does not limit the HMS to indicate which HNB sends the first CSG update request message to the HNB-GW, and an HNB in the CSG cell may be configured in advance as an HNB that can send the first CSG update request message to the HNB-GW. Once the HNB receives the CSG update indication message sent by the HMS, the HNB may send a first CSG update request message to the HNB-GW.

102. Send a second CSG update request message to the core network device, where the second CSG update request message includes an old CSG identifier of the home base station and a new CSG identifier, so that the The core network device updates the subscription information of the user and the CSG identification information stored in the UE according to the old CSG identifier and the new CSG identifier.

After receiving the first CSG update request message, the HNB-GW may send a second CSG update request message to the core network device, where the second CSG update request message may include the old CSG ID of the HNB and the new CSG ID. This embodiment does not limit which network element in the core network device is specifically in the core network. A person skilled in the art may store the subscription information of the UE on any network element on the core network, and receive the second CSG update sent by the HNB-GW. The message is requested to update the subscription information of the UE it stores.

Specifically, in the prior art, a consistent CSG whitelist is stored on the UE and the core network device. When the core network device learns that the CSG whitelist changes, it can use the over-the-air technology (Over-the-Air Technology). The following is abbreviated: OTA or Open Mobile Alliance Device Management (hereinafter referred to as OMA DM) to update the CSG whitelist on the UE. The CSG cell may include the CSG ID of the CSG cell in the system broadcast message during the process of communicating with the UE. After obtaining the CSG ID, the UE can compare the CSG ID with the CSG whitelist saved locally by the UE. If the CSG ID is in the CSG whitelist, the UE can access the HNB in the CSG cell, if not in the CSG white. In the list, the UE cannot access the CSG cell. However, once the HMS modifies the CSG ID of the entire CSG cell or modifies the CSG ID of one or some HNBs in the CSG cell, the CSG ID recorded in the core network device and the allowed UE in the access network The CSG IDs of the accesses are inconsistent, resulting in the CSG IDs recorded in the UE being inconsistent with the CSG IDs in the access network. Therefore, the CSG cell broadcasts the modified CSG ID in the system broadcast message, and the UE considers that the modified CSG ID is not in the CSG white list according to the locally recorded CSG whitelist, that is, the UE cannot access the CSG that modifies the CSG ID. Community.

In this embodiment, after receiving the first CSG update request message sent by the HNB in the CSG cell, the HNB-GW may send the second CSG identifier and the new CSG identifier to the core network device. CSG update request message. When the core network device receives the second CSG After updating the request message, the core network device may update the subscription information of the user and the CSG identification information stored in the UE according to the old CSG identifier and the new CSG identifier. For example, after receiving the second CSG update request message, the core network device can learn that the access network performs the modification of the CSG ID. Therefore, the core network device can update the old CSG ID in the CSG white list in the user subscription information to the new CSG ID. Moreover, the core network device may also update the CSG ID information stored in the UE, for example, update the old CSG ID in the CSG whitelist on the UE to a new CSG ID by using OTA or OMA DM. At this point, the user subscription information stored on the core network device and the CSG ID information stored on the UE are consistent with the modified CSG ID of the HMS in the access network. Therefore, even if the HMS modifies the CSG ID, the UE can know the modified CSG ID in time, and can use the modified CSG ID to access the CSG cell, and the UE cannot access the CSG ID after modifying the CSG ID. The phenomenon of a CSG cell that originally had access.

In this embodiment, after the HMS modifies the CSG ID of the CSG cell, the HNB in the CSG cell may send a first CSG update request message to the HNB-GW, and the HNB-GW may send a second CSG update request message to the core network device. Therefore, the core network device can update the locally stored user subscription information and the CSG identification information stored in the UE according to the old CSG identifier and the new CSG identifier included in the second CSG update request message. Therefore, the user subscription information stored on the core network device and the CSG ID information stored on the UE are consistent with the HSG modified CSG ID in the access network. Even if the HMS modifies the CSG ID, the UE can know the modified CSG ID in time, so that it can know whether it has the right to access the CSG ID modified CSG cell, and the UE cannot be modified after the HMS modifies the CSG ID. The phenomenon of entering a CSG cell with access to it.

FIG. 2 is a flowchart of another embodiment of the method for processing the identifier update according to the present invention. As shown in FIG. 2, the method in this embodiment is an embodiment of the method performed by the HNB corresponding to the method in the embodiment shown in FIG. The method is as follows:

201. Receive a CSG update indication message sent by the home base station management system, where the CSG is further The new indication message contains a new CSG identity.

For example, one or more HNBs in the CSG cell may receive a CSG update indication message sent by the HMS, where the CSG update indication message may include a new CSG ID of the CSG cell.

Specifically, when the HMS needs to modify the CSG ID of the CSG cell, the HMS may send a CSG update indication message to the HNB in the CSG cell. In a specific implementation, the HMS may send a CSG update indication message to all HNBs in the CSG cell, but only one HNB of the HNBs may report a new CSG ID to the core network device, where the HNB may be, for example, the HNBs. The HNB with the highest security, the smallest load, or the closest one; or the HMS may directly send a CSG update indication message to an HNB in the CSG cell, where the HNB may be the HNB with the highest security, the smallest load, or the closest distance in the CSG cell. The HNB can report the modified CSG ID to the core network device, and can also send the modified CSG ID to other HNBs in the CSG cell. For a case where there is only one HNB in the CSG cell, the unique HNB can send the modified CSG ID to the core network device.

It should be noted that, in this embodiment, the HMS does not need to indicate which HNB of the multiple HNBs can send the first CSG update request message, and in this embodiment, the HMS may not necessarily indicate which HNB sends the HNB-GW to the HNB-GW. a first CSG update request message, an HNB in the CSG cell may be configured in advance as an HNB that can send a first CSG update request message to the HNB-GW, and if the HNB receives the CSG update indication message sent by the HMS, The HNB may send a first CSG update request message to the HNB-GW.

202. Send a first CSG update request message to the home base station gateway, where the first CSG update request message includes a new CSG identifier of the home base station.

The HNB selected by the HMS or the pre-configured HNB in the CSG cell may send a first CSG update request message to the HNB-GW, so that the new CSG ID of the HNB, that is, the CSG ID of the CSG cell, is sent to the HNB-GW. . Therefore, after receiving the first CSG update request message, the HNB-GW can send the old CSG identifier and the new network device to the core network device. The second CSG update request message of the CSG identity. After receiving the second CSG update request message, the core network device may update the subscription information of the user and the CSG identification information stored in the UE according to the old CSG identifier and the new CSG identifier. For example, after receiving the second CSG update request message, the core network device can learn that the access network performs the modification of the CSG ID. Therefore, the core network device can update the old CSG ID in the CSG white list in the user subscription information to the new CSG ID. Moreover, the core network device may also update the CSG ID information stored in the UE, for example, update the old CSG ID in the CSG whitelist on the UE to a new CSG ID by using OTA or OMA DM. At this point, the user subscription information stored on the core network device and the CSG ID information stored on the UE are consistent with the modified CSG ID of the HMS in the access network.

In this embodiment, even if the HMS modifies the CSG ID, the HNB can notify the core network device of the new CSG ID through the HNB-GW, so that the core network device can update the locally stored user subscription information and the CSG stored on the UE. ID information. Therefore, the UE can know the modified CSG ID in time, so as to know whether it has the right to access the CSG ID modified CSG cell, and the HMS does not modify the CSG ID, and the UE cannot access the original CMS ID. The phenomenon of the incoming CSG cell.

The technical solutions of the identification update processing method of the present invention will be described in detail below with reference to a few specific embodiments.

FIG. 3 is a signaling flowchart of still another embodiment of the identifier update processing method of the present invention. In this embodiment, a scenario in which a new CSG ID completely replaces an old CSG ID can be processed, that is, all HNBs in the CSG cell need to be old. The CSG ID ^ίι爹 is changed to the new CSG ID. For example, if the HMS instructs the HNB to change the CSG ID from 1 to 2, then all HNBs with a CSG ID of 1 should change the CSG ID to 2, and the original access rights. The UE to the HNB with the CSG ID of 1 has the right to access the HNB with the CSG ID of 2, and all the entries of the CSG whitelist in the CSG whitelist on the core network device and the UE are updated to the CSG ID of 2. Specifically, the method of this embodiment can be as follows: 301. The HMS sends a CSG update indication message to the selected HNB.

For example, the HMS may send a CSG UPDATE message to the HNB, and the CSG UPDATE message may instruct the HNB to modify the CSG ID, that is, the CSG UPDATE message includes a new CSG ID (hereinafter referred to as: new CSG ID).

The modification of the CSG ID needs to be reported to the core network device, and the HNBs in the CSG cell may have the capability difference. Some HNBs have the ability to report information and some HNBs do not have the ability to report information. Therefore, the HMS can be based on the pre- The policy is to select an HNB from the HNBs that have the capability of reporting information to report the modification of the CSG ID to the core network device through the HNB-GW. The preset policy may be the highest security, the lightest load, the closest to the HNB-GW, and the like, and is not limited in this embodiment. In a specific implementation, the indication may be implemented by including the reporting indication information in the CSG update indication message, for example, the reporting indication information (hereinafter referred to as report indication) may be included in the CSG UPDATE message.

302. The selected HNB sends a first CSG update request message to the HNB-GW.

For example, the selected HNB can send HNB CSG Update to HNB-GW.

Required message, the HNB CSG Update Required message may include a new CSG ID, thereby notifying the HNB-GW that the CSG ID is to be tampered with.

303. The HNB-GW sends a second CSG update request message to the core network device.

For example, the HNB-GW may send a CSG UPDATE message to the core network device through the IU port, where the CSG UPDATE message includes a new CSG ID and an old CSG ID (hereinafter referred to as: old CSG ID).

304. The core network device sends a second CSG update response message to the HNB-GW.

For example, the core network device may send a CSG UPDATE RESPONSE message to the HNB-GW, where the CSG UPDATE RESPONSE message includes a timer parameter (hereinafter referred to as a "Timer parameter"). This Timer parameter is used to indicate when the new CSG ID is valid on the HNB.

305. The HNB-GW sends a first CSG update response message to the selected HNB. For example, the HNB-GW may send an HNB CSG UPDATE RESPONSE message to the selected HNB, and the HNB CSG UPDATE RESPONSE message also includes a Timer parameter.

306. The HNB-GW sends a third CSG update response message to other HNBs in the CSG cell.

For example, the HNB-GW can save the CSG ID reported by the HNB at the time of registration. Therefore, the HNB-GW can learn other HNBs that use the old CSG ID, that is, the selected HNBs in the CSG cells that need to modify the CSG ID. Other HNBs outside. The HNB-GW may send an HNB CSG UPDATE RESPONSE message to the HNBs, where the message includes not only the Timer parameter but also the new CSG ID, thereby indicating that other HNBs in the CSG cell modify their CSG ID, and the modified CSG ID is in the Timer parameter. Effective on arrival.

It should be noted that there may be no sequence between step 305 and step 306, as long as the HNB-GW receives the CSG UPDATE RESPONSE message sent by the core network device.

307. The core network device updates the user subscription information.

The core network device can replace the old CSG ID entry in the CSG whitelist in the UE subscription information with the new CSG ID.

It should be noted that the step 307 may be performed after the step 303, and the specific timing of the step 307 is not limited in this embodiment.

308. The core network device updates the CSG ID information stored on the UE.

For example, the core network device can interact with the UE through OTA or OMA DM to complete the CSG whitelist update on the UE. The mode of the OTA or the OMA DM is prior art, and details are not described herein again.

Finally, all HNBs in the CSG cell can enable the new CSG ID when the timing time arrives, thus ensuring the consistency of the new CSG ID.

In this embodiment, when the HSG replaces the CSG ID of the CSG cell as a whole, the HMS may indicate A certain HNB in the CSG cell reports a new CSG ID to the core network device, so as to ensure the security and reliability of the report, and the core network device can also indicate the effective time of the HNB in the CSG cell to use the new CSG ID. The new CSG ID of each HNB is updated synchronously. Therefore, in the scenario where the new CSG ID completely replaces the old CSG ID, the user subscription information stored on the core network device and the CSG ID information stored on the UE are both maintained with the modified CSG ID in the access network. Consistent. Even if the HMS modifies the CSG ID, the UE can know the modified CSG ID in time, so that it can know whether it has the right to access the CSG ID modified CSG cell, and the UE cannot be modified after the HMS modifies the CSG ID. The phenomenon of entering a CSG cell with access to it.

FIG. 4 is a signaling flowchart of still another embodiment of the method for processing an identifier update according to the present invention. This embodiment is also a scenario in which the new CSG ID can be completely replaced by the old CSG ID, and the embodiment and the method embodiment shown in FIG. 3 are used. The difference is that, in the embodiment shown in FIG. 3, the HMS sends only the new CSG ID to the selected HNB, and then the selected HNB reports the new CSG ID to the core network device and sends the new CSG to the other HNBs in the CSG cell. ID, but in this embodiment, the HMS may send a new CSG ID to all HNBs in the CSG cell, and instruct one of the HNBs to report the new CSG ID to the core network device. Specifically, the method of this embodiment can be as follows:

401. The HMS sends a CSG update indication message to the selected port.

This step is similar to the implementation principle of step 301 shown in FIG. 3 above, and details are not described herein again.

402. The HMS sends a CSG update indication message to the other node.

The difference between the CSG update indication message sent to the other port in step 402 and the CSG update indication message sent to the selected port in step 401 is that the CSG UPDATE message in step 402 does not include the report Indication.

403. The selected HNB sends a first CSG update request message to the HNB-GW.

404. The HNB-GW sends a second CSG update request message to the core network device.

405. The core network device sends a second CSG update response message to the HNB-GW.

406. The HNB-GW sends a first CSG update response message to the selected HNB. Steps 403 to 406 are similar to steps 302 to 305 shown in FIG. 3, and details are not described herein again.

407. The HNB-GW sends a third CSG update response message to other HNBs.

The difference between the step and the step 306 shown in FIG. 3 is that, since the new CSG ID has been notified to the other HNBs in the step 402, the HNB CSG UPDATE RESPONSE message may not include the new CSG ID, but needs to include the Timer parameter.

It should be noted that there may be no sequence between step 406 and step 407, as long as the HNB-GW receives the CSG UPDATE RESPONSE message sent by the core network device.

408. The core network device updates the user subscription information.

409. The core network device updates the CSG ID information stored on the UE.

Steps 408 to 409 are similar to steps 307 to 308 shown in FIG. 3, and are not described herein again.

In this embodiment, when the CSG ID of the CSG cell is replaced as a whole, the HMS may send a new CSG ID to all the HNBs in the CSG cell, and instruct a certain HNB in the CSG cell to report a new CSG ID to the core network device. Therefore, the security and reliability of the reporting are ensured, and the core network device can also indicate the effective time of the HNB in the CSG cell to use the new CSG ID, thereby ensuring that the new CSG ID of each HNB is updated synchronously. Therefore, in the scenario where the new CSG ID completely replaces the old CSG ID, the user subscription information stored on the core network device and the CSG ID information stored on the UE are both maintained with the modified CSG ID of the HMS in the access network. Consistent. Even if the HMS modifies the CSG ID, the UE can know the modified CSG ID in time, so that it can know whether it has the right to access the CSG ID modified CSG cell, and the UE cannot be modified after the HMS modifies the CSG ID. The phenomenon of entering a CSG cell with access to it.

FIG. 5 is a signaling flowchart of another embodiment of an identifier update processing method according to the present invention. This embodiment is also a scenario in which a new CSG ID part can be replaced by an old CSG ID, for example, HMS refers to It is shown that some HNBs in the CSG cell change the CSG ID from 1 to 2, and other HNBs in the CSG cell do not need to change the CSG ID, and still use CSG ID 1. The original access to the HNB with the CSG ID of 1 also has the right to access the HNB with the CSG ID of 2. Therefore, the entry of the CSG ID of the CSG whitelist on the core network device and the UE needs to be updated to The CSG ID is 2 and 1. Specifically, the method of this embodiment can be as follows:

501. The HMS sends a CSG update indication message to the selected HNB.

The difference between the step and the step 301 shown in FIG. 3 is that the CSG UPDATE message in this embodiment includes not only the new CSG ID and the report Indication, but also the identification information of the home base station that needs to update the CSG ID. For example, the requirement is needed. The identification information of the home base station that updates the CSG ID may be a list of identifiers of the HNBs to be updated (hereinafter referred to as updating HNB list). The identifier of the HNB in the CSG cell that needs to be updated may be included in the identifier list, so that the CSG ID of the partial HNB can be updated.

502. The selected HNB sends a first CSG update request message to the HNB-GW.

The difference between the step and the step 302 of the foregoing embodiment is that the HNB CSG Update Required message in this embodiment includes not only the new CSG ID but also the HDB list, thereby notifying the HNB-GW which HNBs are involved in the modification of the current CSG ID. .

503. The HNB-GW sends a second CSG update request message to the core network device.

504. The core network device sends a second CSG update response message to the HNB-GW.

505. The HNB-GW sends a first CSG update response message to the selected HNB.

Steps 503 to 505 are similar to the implementation principles of steps 303 to 305 shown in FIG. 3, and are not described herein again.

506. The HNB-GW sends a third CSG update response message to other HNBs.

This step is similar to the step 306 shown in FIG. 3, and the difference is that, since the HNB-GW in step 502 has learned the HNB list of the HNB involved in the modification of the CSG ID, the HNB-GW can be based on the up Hating HNB list. A part of the HNBs in the CSG cell sends a CSG UPDATE RESPONSE message containing the new CSG ID instead of the CSG cell. All HNBs except the selected HNB.

It should be noted that there may be no sequence between step 505 and step 506, as long as the HNB-GW receives the CSG UPDATE RESPONSE message sent by the core network device.

507. The core network device updates the user subscription information.

508. The core network device updates the CSG ID information stored on the UE.

Steps 507 to 508 are similar to steps 307 to 308 shown in FIG. 3, and are not described herein again.

In this embodiment, when the CSG ID part of the CSG cell is replaced, the HMS may send a new CSG ID and identification information of a part of the HNB in the CSG cell to the selected HNB, and the selected HNB may The new CSG ID and the identification information of the part of the HNB are reported to the HNB-GW. When the HNB-GW sends the new CSG ID to the core network device and receives the response message fed back by the core network device, the new CSG can be sent. The ID is sent to a part of the HNB in the CSG cell, so as to complete the modification operation of the CSG ID of the HNB in the CSG cell, and the core network device can also indicate the effective time of the HNB in the CSG cell to use the new CSG ID, thereby ensuring each HNB's new CSG ID is updated synchronously. Therefore, in the scenario where the new CSG ID replaces the old CSG ID of the partial HNB in the CSG cell, the user subscription information stored on the core network device and the CSG ID information stored on the UE are both modified with the HMS in the access network. The subsequent CSG ID remains the same. Even if the HMS modifies the CSG ID, the UE can know the modified CSG ID in time, so that it can know whether it has the right to access the CSG ID modified CSG cell, and the UE cannot be modified after the HMS modifies the CSG ID. The phenomenon of entering a CSG cell with access to it.

FIG. 6 is a signaling flowchart of another embodiment of an identifier update processing method according to the present invention. This embodiment may process a scenario in which a part of HNBs in a CSG cell is allocated to a new CSG cell, and the new CSG cell may be a newly defined CSG cell. HMS can indicate in the original CSG cell Some HNBs change the old CSG ID to a new CSG ID, for example, from 1 to 2. The UEs that have access to these HNBs do not have the right to access the new CSG cell after the CSG IDs of these HNBs are changed. Therefore, the CSG whitelists in the UE and the core network devices are not updated. The method of this embodiment can be as follows:

601. The HMS sends a CSG update indication message to the HNB.

For example, the HMS may send a CSG UPDATE message to the HNB, and the CSG UPDATE message may instruct the HNB to perform the modification of the CSG ID, that is, the CSG UPDATE message includes the new CSG ID. Specifically, the ΗΝΒ in this embodiment may be a partial HNB in the CSG cell, and the HMS may send the CSG UPDATE message only to the HNB whose CSG ID needs to be modified. In this method, the UE does not need to know the change at the UE and the core network device. Therefore, the HMS does not need to indicate that one of the HNBs reports the new CSG ID to the core network device.

602. The HNB sends a first CSG update request message to the HNB-GW.

The HNB that receives the CSG UPDATE message may send an HNB CSG Update Required message to the HNB-GW, and the HNB CSG Update Required message may include a new CSG ID, thereby notifying the HNB-GW that the CSG ID is to be modified. These HNBs can then use the new CSG ID.

In this embodiment, when the HMS needs to divide a part of the HNBs in the CSG cell into the new CSG cell, the HMS may send a CSG update indication message to the HNBs that need to be allocated to the new CSG cell, so that the HNBs can Use the new CSG ID. The UEs that have the right to access these HNBs do not have the right to access the new CSG cell after the CSG IDs of these HNBs are changed. Therefore, the CSG whitelists in the UE and the core network devices are not updated.

FIG. 7 is a signaling flowchart of another embodiment of the identifier update processing method of the present invention. This embodiment can also process a scenario in which a part of the HNBs in the CSG cell are allocated to a new CSG cell. This embodiment and the embodiment shown in FIG. The difference is that, in this embodiment, the HMS sends only the CSG update indication message to the selected HNB, and the CSG update indication message includes the new CSG ID. In addition, the identification information of the partial HNBs that need to be allocated to the new CSG cell is also included, and after the selected HNB sends the new CSG ID and the identification information of the HNBs to the HNB-GW, the HNB-GW needs to be A part of the HNBs allocated to the new CSG cell transmits a new CSG ID. The method of this embodiment can be as follows:

701. The HMS sends a CSG update indication message to the selected HNB.

This step is similar to the implementation principle of step 501 shown in FIG. 5, and details are not described herein again. It should be noted that the HNB selected in this embodiment is an HNB selected from a part of HNBs that need to be allocated to a new CSG cell.

702. The selected HNB sends a first CSG update request message to the HNB-GW.

This step is similar to the implementation principle of step 502 shown in FIG. 5, and details are not described herein again.

703. The HNB-GW sends a third CSG update response message to other HNBs.

The difference between this step and step 506 shown in FIG. 5 is that the Timer parameter is not included in the CSG UPDATE RESPONSE message in this step.

In this embodiment, when the HMS needs to divide a part of the HNBs in the CSG cell into the new CSG cell, the HMS may send a CSG update indication message to the selected one HNB that is allocated to the new CSG cell, the CSG update indication. The message includes the identification information of the HNB divided into the new CSG cell, and then the selected HNB can send the first CSG update request message to the HNB-GW, and divide the new CSG ID into new ones. The identification information of the HNB in the CSG cell is notified to the HNB-GW, so that the HNB-GW can notify the new CSG ID to other HNBs that are allocated to the new CSG cell except the selected HNB. Therefore, the UEs that have access to these HNBs do not have the right to access the new CSG cell after the CSG IDs of these HNBs are changed. Therefore, the CSG whitelists in the UE and the core network devices are not updated.
