Description

Method and device for updating and accessing CSG cell information The present application claims to be submitted to the Chinese Patent Office on March 14, 2011, the application number is 201110060232.2, and the invention name is "a method for CSG cell information update and access control". The priority of the Chinese Patent Application, the entire disclosure of which is incorporated herein by reference. Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for CSG cell information update and access control. Background technique

CSG (Closed Subscriber Grou) is a small network that covers a limited area and serves a specific user, called a closed user group. This type of network can only be accessed by users belonging to the group. Before accessing the network, the terminal first reads the identifier of the CSG cell from the CSG cell, and matches the identifier of the read CSG cell with the identifier of the CSG cell in the CSG list stored by the terminal, so as to determine whether the CSG can be accessed. Community.

The prior art provides a method for updating a CSG list initiated by a network side, where the mobile management entity (Mobile Management Entity) and the terminal's allowed access list (CSG list) When there is a discrepancy, the CSG list on the network side is updated by the Home Subscriber Server (HSS), and the user of the PDN-GW (Public Data Network-Gateway) is updated with the CSG list on the user side. When the terminal's CSG list needs to be updated, if the terminal is in the connected state, the CSG list is directly transmitted to the terminal through the user plane, and the terminal updates its own CSG list; if the terminal is in the idle (IDLE) state, it can be triggered. Paging, passing the updated CSG list to the terminal.

However, if the terminal cannot be paged for some reason, the CSG list on the network side cannot be kept consistent with the user equipment side in a certain period of time, and the terminal cannot access the network resources reasonably, thereby reducing the utilization of network resources. effectiveness.

With the development of diverse data services, a large number of machine type communications (Machine Type Communications, M2M) was introduced. Many MTC terminal deployments are not controlled by operators. For example, MTC terminals deployed by national grid, gas company or water company are only through USIM. The (Universal Subscriber Identity Module) card is connected to the carrier's network. Therefore, the operator cannot accurately identify each MTC terminal. When the MTC terminal needs to access the network, it will use the remote access. The way is to abandon the nearby home base station and connect to the remote macro base station. That is, the deployment of the home base station and the deployment of the MTC terminal are difficult to coordinate with each other, and the access control of the MTC terminal cannot be directly implemented by using the above method, thereby causing the MTC terminal to fail to select an appropriate access node.

It can be seen that, for the MTC terminal, the deployment of the home base station is difficult to coordinate with each other, so that the access control of the MTC terminal cannot be implemented by the prior art; for other terminals, the CSG list and the terminal side of the network side exist. Inconsistent situations make the terminal unable to access properly. Even if the deployment of the MTC terminal and the home base station can be coordinated with each other, there is still a case where the CSG list on the network side is inconsistent with the terminal side, so that the MTC terminal cannot be properly accessed.

The prior art also provides an access control method for a terminal. In the method, when the terminal accesses the local device, the CSG list of the base station is ignored, but the access is directly performed, and the home base station sends the related information of the terminal to the core network. The core network authenticates to allow or deny access to the terminal.

It can be seen that this method ignores the limitation of the CSG list. For the MTC terminal or other terminals, malicious terminals constantly try to access, which has a greater impact on the wireless access of the home base station, and complies with the CSG protocol. The terminal does not attempt to access the network, so the method still fails to enable the terminal to properly access network resources and effectively utilize network resources.

The above described objects, features and advantages of the present invention will become more apparent from the aspects of the appended claims.

In the embodiment of the present invention, the MTC terminal receives the cell information that is sent by the CSG cell, and obtains the CSG cell information that can be accessed according to the received cell information, and reports the information to the core network, and the CSG cell information that the core network obtains for the MTC terminal. Confirming and transmitting the CSG cell information or the acknowledgment information of the CSG cell information that can be accessed by the acknowledgment to the MTC terminal, and the MTC terminal confirms the CSG cell information that is allowed to access or the CSG cell information that can be accessed. The information is updated to the CSG cell information, thereby solving the problem that the CSG cell information of the network side and the MTC terminal side are inconsistent due to the inability of the MTC terminal to page, and the timely updating of the CSG cell information of the MTC terminal is ensured, so that the MTC terminal can be properly accessed. Network equipment, rational use of network resources. The CSG cell information that the MTC terminal can access according to the received cell information, and the CSG cell information that the core network returns to allow access, can usually be expressed in the form of a CSG list (such as Al lowed CSG L i s t ). The CSG list in the embodiment of the present invention may be used to record the CSG identifier of the network node accessible by the MTC, and may further include other information, such as access mode information.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1 In the first embodiment of the present invention, an LTE (Long Term Evolution) system architecture is taken as an example, and a CSG list update process is proposed. The process may include the following steps:

Step 201: The MTC terminal receives the cell information sent by the CSG cell, and obtains a CSG list according to the received cell information.

Specifically, the MTC terminal may receive the information sent by the CSG cell by using a cell measurement or detection process, and generate a CSG list that can be accessed according to the received information of the CSG cell. The MTC terminal can measure the network access nodes around the MTC terminal in a preset manner, for example, in an idle state, or can trigger the measurement by setting a specific event. The CSG list may include information about one or more cells that the MTC terminal can detect. The specific implementation of the cell information received by the MTC terminal in this step and the CSG list that can be accessed according to this can be used in the existing manner.

Step 202: The MTC terminal sends the CSG list that can be accessed to the base station.

Step 203: The base station sends the CSG list that can be accessed to the MME.

Step 204: The MN confirms the CSG list that can be accessed by the MTC terminal according to the MTC terminal related information (such as the subscription information) stored by the HSS, and obtains the CSG list that is allowed to access by confirming. Or the confirmation information of the CSG list that can be accessed by the terminal.

Specifically, when the MN confirms the CSG list that can be accessed by the MTC terminal, the MME first sends a request for acquiring the information about the MTC terminal (such as the subscription information) to the HSS, and after obtaining the related information returned by the HSS, according to the The related information returned by the acquired HSS confirms the CSG list that the MTC terminal can access. For example, the subscription information of the MTC terminal specifies the requirements of the cell that the MTC terminal can access, and if the E-E determines that a cell in the CSG list reported by the MTC terminal meets the requirement of the subscription information, the MTC terminal reports the The cell in the CSG list is confirmed to pass, otherwise it will not be confirmed. The message between the MME and the H S S can be forwarded by the PGW (PDN-Ga teway, Packet Data Gateway).

The MME may generate a CSG list for allowing access according to the result of the acknowledgment. The CSG list may record the identifier of the CSG cell that the MME has confirmed to allow the terminal to use, and may further include other information related to the terminal accessing the CSG cell. Based on the result of the confirmation, the MN may also generate acknowledgment information of the CSG cell information that can be accessed by the terminal side, and the acknowledgment information may indicate that the terminal side is allowed or not allowed to update according to the CSG list that it reports.

Step 205: The MME instructs the HSS to update its stored CSG of the MTC terminal according to the result of the confirmation. List.

Specifically, the E-E can send the CSG list that is allowed to access or the acknowledgment information of the CSG list that can be accessed to the HSS, and the HSS updates the stored CSG list of the MTC terminal according to the CSG list or the acknowledgment information sent by the E-E. .丽 E can forward the CSG list or confirm the information to the HSS through the PGW.

Step 206: The solid E sends the CSG list that is allowed to access or the acknowledgement information of the CSG list that can be accessed to the MTC terminal through the control plane (that is, through the control plane signaling), and the MTC terminal updates the CSG list on the MTC terminal according to the acknowledgement information. That is, the original CSG list of the MTC terminal is updated according to the CSG list confirmed in step 204.

An alternative to step 206 is: solid E will send the CSG list or acknowledgment information for access to the HSS, and the HSS sends to the MTC terminal through the user plane (ie, through user plane signaling); another alternative to step 206 After the CSG updates the CSG list of the MTC terminal that is stored by the HSS, the CSG list or the acknowledgment information corresponding to the access is generated according to the update result, and is sent to the MTC terminal through the user plane signaling.

When the MTC terminal accesses the CSG cell, it can access from the CSG cell in the updated CSG list. Specifically, the MTC terminal can select one CSG cell from the CSG list for access, or can also be used from the detected CSG cell. Select one and find if the selected CSG cell ID is updated.

In the CSG list, if it exists, it accesses the CSG cell.

Through the above process, the MTC terminal actively reports the CSG list obtained by means of cell measurement or detection to the core network side for confirmation. On the one hand, the core network updates the CSG list of the MTC terminal on the network side after confirmation, on the other hand. After the MTC terminal obtains the confirmation notification of the core network, the local CSG list is updated, so that the MTC terminal and the CSG list on the network side can be updated in time, and the cooperation problem between the MTC terminal and the home base station is solved, and the MTC is guaranteed. The timely update of the terminal CSG list enables the MTC terminal to access appropriate network resources, thereby making reasonable use of network resources.

Embodiment 2

The second embodiment of the present invention provides an access control method. As shown in FIG. 3, the process of the method may include the following steps:

Step 301: The MTC terminal receives system information sent by the base station, where the system information carries the permission access indication information. Specifically, the base station may be a home base station, or another communication base station having a CSG management function, and may set an MTC terminal permission indication information (such as MTC Al owed) in the system information of the base station, and the MTC terminal allows access indication information. It is used to indicate that the MTC terminal is allowed to access the home base station. The MTC terminal allows the access indication information to be 1 bit of identification information, and the value thereof may be 0 or 1. When it is 0, it indicates that the MTC terminal is allowed to access, and when it is 1, it indicates that the MTC terminal is not allowed to access, and vice versa. Also. The MTC terminal allows the access indication information to be carried in one of the S IB1 - 13 system information, or other types of system information, such as MIB/S IB2.

Fig. 4 shows an S IB1 system information format in which an MTC terminal is allowed to access an indication information option. As shown in FIG. 4, the MTC terminal allowed access indication information (csg-MTC enab led) is added to the S IB1 system information. When the MTC terminal allows the value of the access indication to be set to allow, the cell allows the MTC terminal to access.

Step 302: The MTC terminal accesses the home base station or the home base station cell, or/and the home base station or the home, according to the MTC permission access indication information carried in the received system information, when it is allowed to access the base station, The base station cell is added to its own CSG list.

The home base station may indicate that the MTC terminal is allowed to access by adding an MTC access indication information item, and indicates that the MTC terminal is not allowed to access by not adding the MTC Allow Access indication information item in the system information. Alternatively, the home base station may add the MTC permission access indication information in the system information, and set the value to a parameter value indicating whether the MTC terminal is allowed to access. For example, a parameter value of 1 indicates that the MTC terminal is allowed to access, and the parameter value is 0 indicates that the MTC terminal is not allowed to access. After receiving the system information sent by the home base station and the parameter value is 0, the MTC terminal does not access the home base station or the home base station cell, and does not access the home base station or the home base station cell. Join the CSG list of the MTC terminal.

Through the above process, it can be seen that the MTC terminal is allowed to access the indication information in the system message sent by the base station, so that the MTC terminal can access the appropriate serving cell and use the network reasonably without violating the existing procedures. Resources, and further avoid the problem that a malicious MTC terminal attacks a home base station when the MTC terminal directly accesses.

It should be noted that, in the foregoing embodiments of the present invention, the home base station may also be replaced by a base station. In addition, the MTC terminal can also be replaced by other types of terminals. In this case, compared with the method for initiating CSG list update by the network side in the prior art, the CSG list update mode initiated by the network side is solved. The terminal side may not receive the problem of the CSG list updated by the network side; it is ignored in the prior art. Compared with the method for directly accessing the CSG list, the terminal can perform reasonable access according to the access indication information carried in the system message.

It should be noted that, in the foregoing embodiment of the present invention, the cell information of the accessible home base station is described by taking the CSG list as an example. In practical applications, other information for the access control of the home base station may also be used.
