Description

Cell access control method, system and device

technical field

The present invention relates to the field of communication technology, in particular to a cell access control method, system and device.

Background technique

When a user equipment (UE, User Equipment) is camping on or accessing (camping/accessing) a certain cell, an access judgment is required. In the prior art, when a UE camps on/accesses a general macro cell, it first needs to perform a cell search on a synchronization channel to obtain time and frequency synchronization of the cell, detect the physical identity of the cell, and then determine whether it can access the area. For example, if the physical identifier of the cell is found in the list of physical identifiers of accessible cells stored by the UE, the UE determines that it can access the cell. After completing the cell search process, if the UE chooses to camp on/access the cell, it will read the primary broadcast channel of the cell. The primary broadcast channel transmits the basic information of the cell and the scheduling information of the dynamic broadcast channel at a fixed time-frequency position in a fixed modulation mode. The capacity of the main broadcast channel is very limited, and other broadcast information is sent in the dynamic broadcast channel. If the UE needs to read the content of the dynamic broadcast channel, it needs to read according to the scheduling information of the dynamic broadcast channel in the main broadcast channel.

With the continuous growth of 3G users and the deepening of research on Long Term Evolution (LTE, Long Term Evolution), indoor base stations (Home NodeB) or indoor Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) access points (AP, AccessPoint) ) has been developed as a wireless access application that can provide high-speed, low-cost services. Indoor base station or indoor UMTS AP technology can make better use of existing network resources, better guarantee the benefits of network equipment operators, and integrate the respective advantages of mobile access networks and fixed access networks.

When the UE camps/accesses a cell based on indoor base station or indoor UMTS AP technology, it also needs to read the access restriction information of the cell, because the number of physical identifiers is very limited, for example, in the broadband code division multiple access mobile communication system ( There are only 512 in WCDMA, Wideband Code Division Multiple Access), and only 510 in LTE, and the number of cells based on indoor base station or indoor UMTS AP technology is much larger than this limited number, so the access restriction information for distinguishing such cells The required length is much longer than the physical identifier, that is, the physical identifier is not enough to distinguish many cells, so the physical identifier is not used as the access restriction information of this type of cell.

At the same time, due to the limited resources of the synchronization channel and the main broadcast channel, the access restriction information of this type of cell is sent on the dynamic broadcast channel in the prior art. When making an access judgment, the UE needs to read the information of the dynamic broadcast channel, and then Judgment of access restriction is performed. From the above description of UE's access to general cells, it can be seen that to read the information of the dynamic broadcast channel, it needs to go through the cell search process, then read the main broadcast channel, and finally read the dynamic broadcast channel according to the scheduling information of the dynamic broadcast channel in the main broadcast channel. The content of the broadcast channel. Therefore, the overhead and time delay for the UE to read the dynamic broadcast channel are relatively large, so when the UE camps on/accesses such a cell, the overhead and time delay for making access judgment will also be relatively large.

Taking a closed subscriber group (CSG, Closed Subscriber Group) cell as an example, users in the CSG cell are served by a CSG cell base station, for example, an indoor base station or a UMTS AP. Each CSG cell can only allow certain users with private network rights to reside or access (camp/access), and these users with access rights form a closed subscriber group (CSG), so services for these users A cell is called a CSG cell.

Fig. 1 is a typical schematic diagram of an indoor access scenario in the prior art. As shown in Figure 1, the UE is a mobile terminal access device, and the indoor base station is routed to the access gateway through the access network to access the wireless UMTS or LTE network; or through the mobile switching center (MSC, Mobile Switch Center)/ The media gateway (MGW, Media Gateway) accesses the public switched telephone network (PSTN, Public Switched Telephone Network); or accesses the Internet. Among them, the access network can be a fixed network network protocol (IP, Internet Protocol) local area network or a digital subscriber line (DSL, Digital Subscriber Line) access network. Therefore, compared with traditional macro base stations, indoor access The method is more flexible and can make full use of the existing fixed network resources.

The access restriction information of the CSG cell may be a CSG identifier, a CSG cell identifier, a public land mobile network (PLMN, Public Land Mobile Network) identifier, a location area (LA, LocationArea) identifier, a routing area (RA, Route Area) identifier or tracking Area (TA, Tracking Area) identification, etc., and then determine whether the CSG cell should be camped on/accessed. At present, the access restriction information of the CSG cell is sent on the dynamic broadcast channel, that is to say, the UE needs to read the information of the dynamic broadcast channel, and then determine the access restriction. From the above description of UE's access to general cells, it can be seen that to read the information of the dynamic broadcast channel, it needs to go through the cell search process, then read the main broadcast channel, and finally read the dynamic broadcast channel according to the scheduling information of the dynamic broadcast channel in the main broadcast channel. The content of the broadcast channel. Therefore, the overhead and time delay for the UE to read the dynamic broadcast channel are relatively large, so when the UE camps on/accesses the CSG cell, the overhead and time delay for making an access judgment will also be relatively large.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 2 is a flow chart of a cell access control method in an embodiment of the present invention. As shown in Figure 2, in step 200 of the method, the base station of the cell sends the access restriction information of the cell on the synchronization channel and/or the main broadcast channel; in step 201, the UE determines whether to Camp/access the cell.

In the following embodiments, the technical solutions provided by the embodiments of the present invention are described in detail by taking a CSG cell as an example.

The CSG cell access restriction information may be information that uniquely identifies a CSG cell or CSG user group, such as a CSG ID, a CSG cell ID, a PLMN ID, a TA ID, an LA ID, or an RA ID.

Embodiment one:

In this embodiment, the CSG cell base station sends all the CSG cell access restriction information on the main broadcast channel in step 300 .

In this step, all of the CSG cell access restriction information refers to all bits of the access restriction information. For example, the access restriction information of the CSG cell is a 24-bit CSG cell ID. In this step, the CSG cell base station sends all 24 bits of the CSG cell ID on the main broadcast channel.

Compared with the macro cell, the CSG cell has a relatively small coverage area and is suitable for home use. Therefore, some information on the main broadcast channel of the macro cell does not need to be broadcast in the CSG cell, and because there are relatively few users in the CSG cell , the available resources are relatively idle, so the capacity of the main broadcast channel for the CSG cell can be larger. Therefore, in this step, all the access restriction information of the CSG cell can be sent on the main broadcast channel.

In step 301, the UE reads all the access restriction information and determines whether to continue camping/accessing the CSG cell. If it matches, it is determined to camp/access the CSG cell, otherwise it is determined not to camp/access the CSG cell.

In this step, after the UE performs the cell search, when reading the primary broadcast channel, it reads all the access restriction information of the cell, so as to make an access judgment.

Therefore, in this embodiment, when the UE performs cell search or reads the primary broadcast channel after the cell search, it can read the access restriction information of the cell, and it does not need to be based on the dynamic broadcast channel scheduling in the primary broadcast channel. information, read the access restriction information, and then make an access judgment. Therefore, the time delay and overhead of reading the cell access restriction information are reduced, and the time delay and overhead of the UE making access judgment before camping on/accessing the CSG cell are reduced.

Embodiment two:

In step 400 of this embodiment, the CSG cell base station sends a part of the cell access restriction information on a synchronization channel, and then sends the rest of the CSG cell access restriction information on a main broadcast channel or a dynamic broadcast channel.

Or the CSG cell base station sends the first part of the cell access restriction information on the synchronization channel, sends the second part of the CSG cell access restriction information on the main broadcast channel, and sends the rest of the CSG cell access restriction information on the dynamic broadcast channel .

Take the access restriction information of the CSG cell as the CSG cell ID as an example. In this step, the length of the CSG cell ID is 24 bits. Specifically, the length of the first part sent on the synchronization channel can be based on the usage of the synchronization channel and the CSG cell ID. Depends on the allocation of identification. For example, the first 4 bits of the 24 bits may be sent on a sync channel.

The method for sending the first part of the CSG cell access restriction information on the synchronization channel may be to bind the first part with the physical identifier of the CSG cell sent on the synchronization channel. When configuring the cell, match the lower 4 bits of the physical identifier of the cell with the lower 4 bits of the CSG cell identifier of the cell.

Then, send the remaining 20 bits of the CSG cell identity on the main broadcast channel or the dynamic broadcast channel, or send the 4 bits of the CSG cell identity on the main broadcast channel, and send the remaining 16 bits of the CSG cell identity on the dynamic broadcast channel.

In step 401, when the UE performs a cell search, it reads the first part of the access restriction information of the CSG cell from the synchronization channel, and determines whether to continue camping on/accessing the CSG cell according to the first part, and if the judgment result is to continue camping When accessing the CSG cell, continue to read the main broadcast channel. If the rest of the access restriction information of the CSG cell is not read on the main broadcast channel, it is necessary to read the dynamic broadcast channel. When the remaining part of the access restriction information of the CSG cell is read from the main broadcast channel or the dynamic broadcast channel, the UE continues to determine whether to camp on/access the CSG cell according to the part of the access restriction information.

Specifically, when performing a cell search, the UE reads the first part of the CSG cell access restriction information from the synchronization channel, and compares the first part with the corresponding part of the access restriction information of the cell it is allowed to access. If it matches, it is judged that it will no longer reside/access the CSG cell; otherwise, continue to read the main broadcast channel. If the main broadcast channel does not read the rest of the access restriction information of the CSG cell, it is necessary to read the dynamic broadcast channel . When the rest of the access restriction information of the CSG cell is read from the main broadcast channel or the dynamic broadcast channel, the UE compares this part with the corresponding part of the access restriction information of the cell it is allowed to access, and if it matches, it decides to continue Camp on/access the CSG cell, otherwise determine not to camp/access the CSG cell.

If the UE determines to continue camping/accessing the CSG cell according to the access restriction information read on the synchronization channel, and reads the second part of the CSG cell access restriction information on the main broadcast channel, then according to the first The second part performs access judgment. If the judgment result still resides/accesses the CSG cell, the access judgment is made according to the rest of the CSG cell access restriction information read from the dynamic broadcast channel.

It can be seen that in this embodiment, the base station of the CSG cell sends a part of the access restriction information on the synchronization channel, so that the UE that does not match the access restriction information of the cell allowed to access the cell determines that it will no longer camp/access the CSG cell ; When the remaining part of the CSG cell access restriction information is sent on the main broadcast channel, the UE that makes the first part match the access restriction information of the cell that it is allowed to access can finally determine whether to continue after reading the main broadcast channel Camping/accessing the CSG cell, thereby reducing the time delay and overhead for the UE to perform access judgment when camping/accessing the CSG cell.

Embodiment three:

In step 500 of this embodiment, the CSG cell base station sends a part of the cell access restriction information on the main broadcast channel, and then sends the rest of the CSG cell access restriction information on the dynamic broadcast channel.

Take the access restriction information of the CSG cell as the CSG cell ID as an example. In this step, the length of the CSG cell ID is 24 bits. Specifically, the length of the first part sent on the main broadcast channel can be based on the usage of the synchronization channel and the CSG It depends on the allocation of cell IDs. For example, the first 4 bits of the 24 bits may be sent on a sync channel.

In step 501, after the cell search is completed, the UE reads the primary broadcast channel, reads the first part of the CSG cell access restriction information from the primary broadcast channel, and determines whether to continue camping/accessing the CSG according to the first part district. If the judgment result is to continue camping/accessing the CSG cell, continue to read the dynamic broadcast channel, and when the dynamic broadcast channel reads the rest of the CSG cell access restriction information, continue to judge whether to camp on according to this part / Access the CSG cell.

Specifically, after the UE completes the cell search, it reads the primary broadcast channel, reads the first part of the CSG cell access restriction information from the primary broadcast channel, and combines the first part with the access restriction information of the cell it is allowed to access. If they do not match, it is determined that they will no longer reside/access the CSG cell; otherwise, continue to read the dynamic broadcast channel, and when the dynamic broadcast channel reads the rest of the CSG cell access restriction information, Compare this part with the corresponding part of the access restriction information of the cell allowed to be accessed by itself, and if they match, decide to continue camping/accessing the CSG cell, otherwise judge not to camp/access the CSG cell.

It can be seen that in this embodiment, the base station of the CSG cell sends a part of the access restriction information on the main broadcast channel, so that the UE that does not match the access restriction information of the cell that it allows to access the cell determines that it will no longer camp/access the CSG Cells, thereby reducing the time delay and overhead for the UE to make access judgments when camping on/accessing a CSG cell.

In the above embodiments, when the UE makes an access judgment, that is, the UE compares the read access restriction information with the access restriction information of the cell it is allowed to access. When no longer camping/accessing the CSG cell, it can be judged to directly compare the access restriction information of the allowed access cell stored by itself, and if the matching information is found, it is judged to camp/access the CSG cell, otherwise it is judged No longer camp on/access the CSG cell. Alternatively, the UE may also use a certain algorithm to calculate a certain value or certain values according to the received access restriction information of the CSG cell, and then use the same algorithm to obtain the access restriction information of the cell that is allowed to access the UE stored by itself. One or some calculated values are compared, and if they match, it is judged to camp/access the CSG cell, otherwise it is judged not to camp/access the CSG cell.

Those skilled in the art should understand that the embodiments described above, in addition to being applied to CSG cells, can also be applied to other cells that send access restriction information through dynamic broadcast channels in the prior art, or some other In scenarios where it is necessary to reduce the delay and overhead of the UE in making access judgments.

The embodiment of the present invention also provides a cell access control system. As shown in FIG. 3 , the system includes a UE and a cell base station.

Wherein, the base station of the cell is used to transmit the access restriction information of the cell on the synchronization channel and/or the main broadcast channel; the user equipment UE is used to determine whether to camp on/access the cell according to the access restriction information of the cell.

The cell base station sends all the access restriction information of the cell on the main broadcast channel; or, the cell base station sends the first part of the cell access restriction information on the synchronization channel, and sends the cell access restriction information on the main broadcast channel and/or dynamic broadcast channel or the cell base station sends the first part of the cell access restriction information on the main broadcast channel, and further sends the rest of the cell access restriction information on the dynamic broadcast channel.

Specifically, the UE includes a reading module and a judging module. Among them, the reading module is used to read the access restriction information of the cell from the synchronization channel and/or the main broadcast channel; the determination module is used to determine whether to reside/ access the area.

The cell base station includes a storage module and a sending module. Wherein, the storage module is used to store the access restriction information of the cell; the sending module is used to send the cell access restriction information stored in the storage module on the synchronization channel and/or the main broadcast channel.

The sending module sends all the cell access restriction information saved by the storage module on the main broadcast channel; or, the sending module sends the first part of the cell access restriction information saved by the storage module on the synchronous channel, and broadcasts on the main broadcast channel and/or dynamically The channel sends the rest of the cell access restriction information; or, the sending module sends the first part of the cell access restriction information on the main broadcast channel, and further sends the rest of the cell access restriction information on the dynamic broadcast channel.

In practical applications, the network of the system and other network elements forming a cell access system is not limited to the access scenario shown in Figure 1, but can be adjusted and modified according to actual conditions.

It can be seen from the above that in the technical solution provided by the embodiments of the present invention, the cell base station sends the access restriction information of the cell on the synchronization channel and/or the main broadcast channel; the UE determines the access restriction information of the cell according to the access restriction information of the cell Whether to camp/access the cell.
