Description

Method and device for updating home base station neighbor cell information

technical field

The invention relates to a method and a device for updating the information of adjacent cells of a home base station.

Background technique

With the rapid development of mobile networks and the reorganization of telecom and mobile operators, seamless access and indoor coverage have increasingly become the focus of operators' attention in the construction of mobile networks. Although the important task of mobile communication is to ensure the wireless communication quality of outdoor users, according to statistical surveys, users spend the longest time using mobile networks indoors. Therefore, good network coverage, especially indoor coverage, is the key to rapid development.

In response to this demand, femtocell technology has received keen attention and favor from operators and equipment manufacturers at home and abroad. On the one hand, femtocells can quickly and cheaply solve the problem of indoor coverage, provide users with high-speed data services and reduce the load on macro base stations, and on the other hand, realize the combination of fixed and mobile for operators, making mobile communication more popular in the home market. get developed. Femtocells are small, low-power base stations. As an exclusive resource for private users, it is mainly deployed and applied in indoor places such as families, schools, companies, and small group areas.

Figure 1 is a schematic diagram of the structure of the home base station system. As shown in Figure 1, the home base station system includes a home base station (HNB, Home NodeB or Home eNodeB), a security gateway (Security Gateway), and a home base station management system (HMS, HNB Management System) and home base station gateway (HNBGW, HNB Gateway), wherein, the home base station is connected to the home base station management system and the home base station gateway through the Iuh interface and the security gateway, the home base station management system is connected to the home base station gateway, and the home base station gateway is connected through The Iu port is connected to the IP network, so as to be connected to the core network (CN, Core Network). Among them, the function of the security gateway is to establish secure network communication; the home base station gateway is introduced to reduce the impact on the core network, and its main function is to provide link connection and service access for the home base station. The home base station management system completes the authentication of the home base station, provides functions such as various configuration parameters for the home base station. Since the home base station is a private user equipment, it can only provide services for some users. The home base station performs information exchange with the mobile terminal (UE) through the Uu interface.

In order to reduce the excessive attempts of mobile phones to access networks that are not allowed, the concept of closed subscriber group (CSG, Closed Subscriber Group) is introduced. Users who are allowed to access the coverage area of the home base station are called CSG users. The area covered by one or more home base stations belonging to this user group is also the CSG area. The cells belonging to the CSG area are called CSG cells. Each CSG is in a mobile network. Identify with a unique CSG identity (CSG ID).

After the HNB is powered on, it starts to scan the information of surrounding macro cells (cells of macro base stations), and provides location information (including macro cells, geographic location, IP connection, etc.) to the HMS. The HMS checks the location information of the Femtocell, allocates a Femtocell gateway to the Femtocell, and sends configuration parameters. After receiving the address of the femtocell gateway, the HNB initiates the establishment of a Stream Control Transmission Protocol (SCTP, Stream Control Transmission Protocol) connection to the destination femtocell gateway. The HNB registers with the femtocell gateway, which contains location information (including macro cell, geographic location, IP connection, etc.), location area, CSG ID, and other information. After the registration is completed, the HNB can provide services for some designated UEs. Here, the designated UEs establish a corresponding relationship table between the UE ID and the CSG ID on the core network and the UE, which is called a white list (White List). The UE tries to access several CSG cells specified in the white list saved by itself, and a certain CSG cell only allows these specific UEs to access. In some cases, there may be multiple Femtocells corresponding to the same CSG ID, so the mobile phone that contains this CSG ID in the white list is allowed to access multiple Femtocells. Therefore, a UE working in the connected state is also allowed to switch between adjacent HNBs with the same CSG ID.

In the macro base station application environment, adjacent cell information (cell identity, frequency point, etc.) is pre-configured in the network management system, and the adjacent cell information can be used in the measurement control process to provide preparation for handover. However, for the femtocell system, since the femtocell is a private user equipment, the startup and shutdown of the femtocell are relatively frequent and irregular, and the number is large, which is not suitable for the pre-manual configuration method. However, if the home base station is set to periodically query the surrounding CSG cells, the work efficiency and power consumption of the home base station will be seriously affected. At present, there is no suitable solution suitable for the home base station to update neighboring cells.

The home base station gateway or the home base station management system determines the home base station to which the CSG cell belongs according to the neighbor cell list of the powered-on home base station, or searches for the home base station with the same CSG ID as the powered-on home base station, and sends a report to the home base station The home base station to which the CSG cell in the neighbor cell list belongs or the home base station with the same CSG ID sends a neighbor cell change notification message, informing it to add the CSG cell of the powered-on home base station in the local neighbor cell list; the home base station shuts down , delete the CSG cell of the disabled HNB from the corresponding neighbor cell list. When the present invention detects that the home base station is powered on or off, it only updates the adjacent cell list of the relevant home base station, without the need for the home base station to periodically query the surrounding CSG cells, and when the home base station is powered on or off, it is not relevant The neighbor list of the femtocell does not need to be updated. The cell update method of the present invention is quite fast and occupies less resources of the communication system.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

Fig. 2 is a flow chart of a method for updating the information of adjacent cells of a home base station according to the present invention. As shown in Fig. 2, the method for updating the information of adjacent cells of a home base station in this example includes the following steps:

Step 201: After receiving the location information of the first home base station and the information of neighboring cells searched when powering on, the management system of the home base station configures a neighboring cell for the first home base station according to the location information and the information of the neighboring cells. cell parameters, and send the neighbor cell parameters to the first home base station, so that it completes the configuration of the neighbor cell list.

The first Femtocell here refers to the Femtocell that is powered on in the Femtocell system. After the Femtocell is powered on, it will start to search for the surrounding cell information, and at the same time perform authentication and registration with the Femtocell management system. The powered-on Femtocell will search for The neighbor cell information and the location information of the home base station are reported to the home base station management system. Wherein, the location information includes network connection information, location information in the global navigation satellite system, etc., and the home base station management system determines the geographic location of the home base station according to the location information reported by the powered-on home base station, so as to determine whether the powered-on home base station is Beyond the restricted area, the home base station management system can also determine its location according to the macro cell information reported by the powered-on home base station. The home base station management system configures neighboring cell parameters for the powered-on home base station according to the neighboring cell information reported by the powered-on home base station, and sends the parameters to the powered-on home base station. Wherein, the adjacent cell information includes radio frequency information and broadcast information of the adjacent cell, and the adjacent cell includes the cell of the macro base station and the CSG cell of the home base station; the parameters of the adjacent cell include cell identity, center frequency point, maximum transmission power, etc.

Step 202: The home base station gateway or the home base station management system determines that the neighbor cell list of the first closed subscriber group CSG cell of the first home base station includes the second home base station according to the neighbor cell parameters of the first home base station The second CSG cell, sending a first neighbor cell change notification message to the second home base station, instructing the second home base station to add the first CSG cell to the neighbor cell list of the second CSG cell; the The first neighbor cell change notification message includes the cell parameters of the first CSG cell.

The second home base station here is any powered-on home base station cell that is different from the powered-on home base station. The Femtocell gateway or the Femtocell management system determines that there are other CSG cells in the neighbor cell list of the powered-on Femtocell, assuming that the CSG cell N of the powered-on Femtocell contains CSG cell M in the neighbor cell list, then search for the CSG cell M belongs to If the home base station is the second home base station, it sends a neighbor cell change notification message to the second home base station, instructing the second home base station to add CSG cell N to the neighbor cell list of CSG cell M, and the notification message includes the cell of CSG cell N parameter.

As a more preferred solution, the method for updating the information of the adjacent cells of the home base station in the present invention also includes:

Step 203: The home base station management system detects that the fourth home base station is shut down or the home base station gateway detects that the fourth home base station is unregistered, and adds the information to the neighbor cell list of the fourth CSG cell of the fourth home base station The fifth home base station to which the fifth CSG cell belongs sends a fourth neighbor cell change notification message, instructing the fifth home base station to delete the fourth CSG cell from the neighbor cell list of the fifth CSG cell; wherein, the The fourth neighbor cell change notification message includes cell parameters of the fourth CSG cell.

When the home base station is shut down, the updated CSG cell neighbor list of the home base station will be determined according to the neighbor cell list of the shut down home base station. For example, the home base station M is closed, and the neighbor cell list of the CSG cell N includes the CSG cell O, and the CSG cell O belongs to the home base station P, then the home base station management system or the home base station gateway will send a neighbor cell change notification message to the home base station P, The home base station P is instructed to delete the CSG cell N from the neighbor cell list of the CSG cell O.

Fig. 3 is a flow chart of the second method for updating the information of the adjacent cells of the home base station in the present invention. As shown in Fig. 3, the method for updating the information of the adjacent cells of the home base station in this example includes the following steps:

Step 301: The Femtocell gateway or the Femtocell management system searches for whether there is a third Femtocell with the same CSG flag according to the acquired CSG identity when the first Femtocell is powered on, and sometimes sends a message to the third Femtocell The second neighbor cell change notification message instructs the third home base station to add the CSG cell of the first home base station to the list of neighbor cells of its own CSG cell, and at the same time, sends the third neighbor cell to the first home base station A change notification message, instructing the first home base station to add the CSG cell of the third home base station to its own CSG cell neighbor cell list; the second neighbor cell change notification message includes the first home base station's A cell parameter of the CSG cell, wherein the third neighbor cell change notification message includes the cell parameter of the CSG cell of the third home base station.

Specifically, the Femtocell management system obtains the CSG identifier of the first Femtocell by finding the first Femtocell according to the MAC address or other identification information of the first Femtocell after receiving the information reported when the first Femtocell is powered on. The CSG identifier of the base station; and the first HNB directly reports the CSG identifier to the HNB gateway. Generally, Femtocells with the same CSG ID belong to the same owner, or, although they belong to different owners but have similar locations, Femtocells with the same CSG ID are generally Femtocells with close geographical locations. The same home base stations are mutually defined as adjacent cells. The third home base station, the second neighbor cell change notification message, and the third neighbor cell change notification message in this step are all general references and are not distinguishing features. For example, the third home base station and the aforementioned second home base station may be the same Femtocell. Throughout the document, the definition of "what number" refers generally. The adjacent cell parameters include a cell identity, a center frequency point, a maximum transmit power, and the like.

Step 302: When the home base station management system detects that the fourth home base station is shut down or the home base station gateway detects that the fourth home base station is unregistered, it searches for whether there is a CSG identifier related to the fourth home base station A seventh home base station with the same CSG identifier of the fourth home base station sometimes sends a fifth neighbor cell change notification message to the seventh home base station, indicating that the seventh home base station is in a neighboring cell of the CSG cell of the seventh home base station. The CSG cell of the fourth home base station is deleted from the cell list; wherein, the fifth neighbor cell change notification message includes cell parameters of the CSG cell of the fourth home base station.

For example, if the home base station M is closed, if the CSG IDs of the home base station M and the home base station P are the same, the home base station management system or the home base station gateway will send a neighbor cell change notification message to the home base station P, instructing the home base station P to replace all its CSG cells Delete all CSG cells under the home base station M from the neighbor cell list.

Step 302 is a preferred technical feature of the present invention, but not a necessary technical feature.

In FIG. 2 , before step 203 , the method of adding adjacent cells described in step 301 may also be included; when it is detected that the home base station is shut down, the method of deleting adjacent cells in step 302 below is correspondingly included. That is to say, the methods shown in FIG. 2 and FIG. 3 are parallel solutions and can be applied to the same technical solution. The solution shown in FIG. 2 can also be applied to the solution shown in FIG. 3 .

Fig. 4 is a flow chart of the third method for updating the information of the adjacent cells of the home base station in the present invention. As shown in Fig. 4, the method for updating the information of the adjacent cells of the home base station in this example includes the following steps:

Step 401: The HNB is powered on, searches the information of neighboring cells of the HNB, and reports the location information of the HNB and the information of the searched neighboring cells to the HNB management system.

The home base station management system configures neighboring cells for the powered-on home base station according to the neighboring cell information reported by the home base station and the location information of the home base station, and sends the configured neighboring cell parameters to the home base station. The home base station gateway and the home base station management system search whether there is a home base station with the same CSG identification as the home base station according to the acquired CSG identification when the home base station is powered on, and sometimes send a neighbor cell change to the home base station A notification message, instructing the home base station to add the CSG cell of the home base station with the same CSG identifier to its own CSG cell. For the processing methods of the Femtocell gateway and the Femtocell management system side when the Femtocell is powered on, refer to the relevant descriptions in FIG. 2 and FIG. 3 , and details will not be repeated here.

The adjacent cell information includes radio frequency information, broadcast information, etc. of adjacent cells, and the adjacent cells include cells of macro base stations and CSG cells of home base stations; the location information includes network connection information, location information in the global navigation satellite system, etc. .

Step 402: After receiving the neighbor cell parameters configured by the Home NodeB management system for the Home NodeB, the Home NodeB completes the configuration of its own neighbor cell list; A neighbor cell change notification message, the home base station adds or deletes the indicated CSG cell in the neighbor cell list of the corresponding CSG cell according to the indication in the neighbor cell change notification message.

The adjacent cell parameters include a cell identity, a center frequency point, a maximum transmit power, and the like.

Compared with the methods shown in FIG. 2 and FIG. 3 , the method shown in FIG. 4 is described based on the perspective of the home base station side, and its implementation is essentially the same as the methods shown in FIG. 2 and FIG. 3 , and will not be repeated here.

The method for updating the adjacent cell information of the home base station of the present invention will be further elaborated below in combination with examples.

Fig. 5 is a flow chart of the first embodiment of the method for updating the adjacent cell information of the home base station according to the present invention. As shown in Fig. 5, this embodiment includes the following steps:

Assume that HNB1 and HNB2 are home base stations connected to the same HMS, and the corresponding CSG IDs are the same, and the cell Cell1 to which HNB1 belongs is adjacent to the cell Cell2 to which HNB2 belongs, which are respectively denoted as Cell1 and Cell2. For the convenience of description, it is assumed that there are no other HNBs with the same CSG ID except HNB1 and HNB2 in the HMS.

Step 501: HNB1 is powered on and enters a working state.

Step 502: HNB2 starts up and scans the surrounding cell information, including the surrounding CSG cell and macro cell information, mainly scanning the radio frequency information and broadcast information of the surrounding cells. HNB2 sends the scanned surrounding cell information and the location information of HNB2 to the HMS. The above location information may include at least one of macro cell information, network connection information, global navigation satellite system location information and CSG cell information.

Step 503: HMS assigns cell configuration parameters and HNB GW address to HNB2 according to the location information reported by HNB2 and sends them to HNB2; HNB2 completes the registration with HNB GW.

HNB2 stores cell information such as cell identities and frequency points of all adjacent cells, and may only store information of cells with the same CSG id.

Step 504: HNB2 sets the adjacent cell configuration.

The adjacent cells of HNB2 include surrounding macro cells or CSG cells. The above adjacent cell configuration includes parameters such as a cell identifier, a center frequency point, and a maximum transmission power.

Step 505: HNB2 registers with HNB GW.

Step 506: The HMS learns that the cell Cell1 is adjacent to the cell Cell2 under the jurisdiction of the HNB2 according to the information of the surrounding CSG cells reported by the HNB2, and the HMS obtains from the local database that the base station corresponding to the Cell1 is HNB1, so that the HMS sends a neighboring cell change notification message to the HNB1, Instruct HNB1 to add the cell information of Cell2 (including cell identity, frequency point, CSG ID, etc.) in the neighbor cell list of Cell1. The neighbor cell change notification message includes cell information of Cell2, message type, information indicating update of neighbor cells, and the like.

The HMS queries all the home base stations with the same CSG ID as the cell HNB2, and sends a neighbor cell change notification message to these base stations. The neighbor cell change notification message includes Cell2’s cell information, message type, information indicating that the neighbor cell is updated (increased), etc. .

Those skilled in the art should understand that the HMS in step 506 can also be replaced by the HNB GW.

There is no strict timing requirement among step 504 , step 505 and step 506 .

Step 507: HNB1 modifies the configuration of neighboring cells, and adds CSG cell Cell2 in the list of neighboring cells of Cell1.

Fig. 6 is a flow chart of the second embodiment of the method for updating the information of the neighboring cells of the home base station according to the present invention. As shown in Fig. 6, this embodiment includes the following steps:

Assume that HNB1 and HNB2 are home base stations connected to the same HMS, and the corresponding CSG IDs are the same, and the cell Cell1 to which HNB1 belongs is adjacent to the cell Cell2 to which HNB2 belongs, which are respectively denoted as Cell1 and Cell2. For the convenience of description, it is assumed that there are no other HNBs with the same CSG ID except HNB1 and HNB2 in the HMS. The scenario shown in FIG. 6 is a flow subsequent to the flow shown in FIG. 5 .

Step 601: HNB1 and HNB2 are powered on and enter the working state.

Step 602: shut down the HNB2, and the HMS detects that the HNB2 is shut down.

Step 603: The HMS searches for the home base station HNB1 with the same CSG identifier according to the CSG identifier corresponding to the cell Cell2 managed by HNB2; the HMS sends a neighbor cell change notification message to HNB1, instructing HNB1 to delete the cell information of Cell2 in the neighbor cell list of Cell1 ( Including cell identification, frequency point, CSG ID, etc.). The neighbor cell change notification message includes cell information of Cell2, message type, information indicating update (deletion) of the neighbor cell, and the like.

According to the maintained adjacent cell, the HMS searches for the home base station of the cell adjacent to HNB2, in this example, HNB1, and the HMS sends a notification message of changing the adjacent cell to HNB1, which instructs HNB1 to delete the cell information of Cell2 in the adjacent cell list of Cell1 ( Including cell identification, frequency point, CSG ID, etc.).
