When the existing home base station switches between different access modes, it needs to be restarted to complete the mode reconfiguration. Therefore, when switching, the mobile terminal connected to the home base station in the home base station and the home base station are connected. Disconnected, affecting the use of mobile terminals. FIG. 1 is a flowchart of a method for switching a home base station mode according to an embodiment of the present invention.

S1: The home base station mode switching device acquires a new access mode. The access modes include: closed mode, open mode, mixed mode, etc., and the mode before the switching is defined as the current access mode, and the mode after the switching is defined as the new access mode. When acquiring a new access mode, the new access mode may be received. For example, the home base station mode switching device receives a new access mode sent by the Home NodeB Management System (HMS), as shown in FIG. 2, which is the present invention. An embodiment of a HMS home base station system network structure, where 1 is a home base station, 2 is an HMS, 3 is a home base station gateway, and Iurh is an interface between home base stations, and Uu is a home base station and a mobile terminal. Between the interface, luh is the interface between the home base station and the home base station gateway, and Iu is the interface between the home base station gateway and the core network. In addition, in some special scenarios, for example, when the home base station initiates an interference management process, the new access mode can be obtained from the instructions in the interference management process.

S2: Determine the access requirement corresponding to the new access mode.

The correspondence between the access mode and the access request is stored in the home base station, and the access requirements of all access modes are also stored. When the new access mode is obtained from S1, according to the correspondence between the access mode and the access requirement, the access request corresponding to the new access mode can be found from the access requirements stored in the home base station.

In addition, in other embodiments of the present invention, access requirements of the new access mode may also be obtained by other means. For example, the access request of the new mode may be received in S1.

S3: Determine whether the mobile terminal currently accessing the home base station meets the access requirement of the new access mode.

After the mode switching, the mobile terminal that meets the access requirement of the new mode can be allowed to access the home base station. Therefore, it is necessary to determine whether the mobile terminal meets the access requirement of the new access mode, so that it can be known whether the mobile terminal is allowed to be in the mobile terminal. The home base station is accessed in the new access mode.

For the closed mode, the access requirement is that the subscription status information is allowed to be accessed by the subscribed mobile terminal; for the hybrid mode, the access requirement is that the subscription status information is allowed for the signed and non-signed mobile terminal access, but for the subscription status information Different access levels and service levels are provided for contracted and non-contracted mobile terminals; and for open mode, the access requirements are for all mobile terminals. Access does not distinguish between subscription status information as contracted and non-contracted mobile terminals. Therefore, in the present invention, whether the mobile terminal currently accessing the home base station meets the access requirement of the new access mode can be determined by determining the subscription status of the mobile terminal.

When the mobile terminal currently accessing the home base station meets the access requirement of the new access mode, it can maintain the connection with the home base station in the new access mode, so that the mobile terminal does not need to be processed. When the mobile terminal currently accessing the home base station does not meet the access requirement of the new access mode, S4 is performed.

S4: Switch the mobile terminal out of the home base station or stop the service.

When the mobile terminal does not meet the access requirement of the new access mode, the mobile terminal may not be able to access the home base station in the new access mode after the mode switching, so the connection between the mobile terminal and the home base station is required. disconnect. In the embodiment of the present invention, the connection between the mobile terminal and the home base station is disconnected, specifically, the mobile terminal is switched to another base station (including a home base station or a macro network base station) or the connection of the mobile terminal is released. In the embodiment of the present invention, for a mobile terminal that needs to be switched or released, it is generally referred to as a Cell-DCH (Cell Dedicated Channel) or a Cell-FACH (Cell Forward Access Channel) in a UMTS system. A mobile terminal in an access channel state or a mobile terminal in a connected state in an LTE system.

In the embodiment of the present invention, after acquiring the new access mode, and before determining whether the mobile terminal currently accessing the home base station meets the access requirement of the new access mode, as shown in FIG. 3, another implementation of the present invention In an example, the method may further include: S5 and S6, wherein:

S5: Send an update request message carrying a new access mode to the home base station gateway.

S6: Receive an update confirmation message sent by the home base station gateway.

The S5 and S6 may send an update request message carrying the new access mode to the home base station gateway during the mode switching process, and notify the home base station gateway to provide corresponding access control in a subsequent step, for example, determining the current Whether the mobile terminal accessing the home base station meets the new The access requirement of the access mode may require the home base station gateway to query the subscription status information of the mobile terminal. The following describes the technical solution of the present invention in detail by using several embodiments to perform the switching between the three access modes of the home base station.

An embodiment:

In the embodiment of the present invention, the current access mode is a hybrid mode, and the new access mode is a closed mode or an open mode; or the current access mode is a closed mode, and the new access mode is a mixed mode or an open mode. In the hybrid mode, the access requirement is that the subscription status information is allowed to be signed or non-signed mobile terminal access, and in the closed mode, the access requirement is that the subscription status information is allowed to be signed by the mobile terminal, so When the current access mode is the hybrid mode or the closed mode, the subscription status information of the mobile terminal currently accessing the home base station is stored in the home base station.

FIG. 4 is still another flowchart of a method for switching a home base station mode according to another embodiment of the present invention. S101: The home base station mode switching device acquires a new access mode.

S102: The home base station mode switching device determines an access requirement corresponding to the new access mode. S103: Search for the subscription status information of the stored mobile terminal that is currently accessing the home base station from the home base station.

Since both the subscription mobile terminal and the non-subscription mobile terminal can access the home base station in the hybrid mode, and the home base station provides different services to the subscription mobile terminal and the non-subscription mobile terminal, that is, the current access home base station is stored in the home base station. The subscription status information of the mobile terminal can be obtained from the subscription status information stored in the home base station, and the subscription status information of the mobile terminal currently accessing the home base station can be obtained from the subscription status information stored in the home base station.

S104: Determine whether the obtained subscription status information meets the access requirement of the new access mode. For the closed mode, the access requirement is to allow the subscription status information to be accessed by the subscribed mobile terminal; for the hybrid mode, the access requirement is to allow the subscription status information to be the subscription and non-signed mobile terminal access; and for the open mode The access requirement is to allow access to all mobile terminals. Therefore, when it is known that the subscription status information of the mobile terminal is contracted or not signed, it is only necessary to compare the subscription status information of the mobile terminal with the access requirement of the new access mode, and it is known whether the mobile terminal is allowed to be in the new access mode. Access to the home base station.

The access request corresponding to the new access mode has been obtained in S102, and the subscription status information of the mobile terminal currently accessing the home base station has been obtained in S103, and in this step, the obtained subscription status information is The new mode access requirements can be compared to determine whether the subscription status information meets the access requirements of the new access mode.

When the obtained subscription status information does not meet the access requirement of the new access mode, proceed to S105.

S105: Switch the mobile terminal out of the home base station or stop the service. Another embodiment:

In the embodiment of the present invention, the current access mode is an open mode, and the new access mode is a closed mode or a mixed mode. Since the home base station allows all mobile terminals to access in the open mode, the subscription status information of the mobile terminal is not stored in the home base station, and the subscription status information of the mobile terminal needs to be obtained from the home base station gateway or the core network.

FIG. 5 is still another flowchart of a method for switching a home base station mode according to another embodiment of the present invention.

S201: The home base station mode switching device acquires a new access mode.

S202: The home base station mode switching device determines an access requirement corresponding to the new access mode.

S203: Send a message to the core network requesting to query the subscription status information of the mobile terminal.

Since the current mode is the open mode, the subscription status information of the mobile terminal is not stored in the home base station, so it is necessary to query the subscription status information of the mobile terminal currently connected to the home base station from the home base station gateway or the core network.

In the embodiment of the present invention, for some systems that do not have a home base station gateway, for example, a HeNB mode handover procedure in the LTE system, when performing mode switching, the home base station does not need to communicate with the home base station gateway, but with the core network MME. ( Management Entity, mobility tube The entity interacts, that is, for those systems that do not have a home base station gateway, in this step, a message requesting to query the subscription status information of the mobile terminal is sent to the core network, and the subscription status information of the mobile terminal is completed by the core network. Query.

S204: Receive subscription status information of the mobile terminal sent by the core network.

After receiving the message requesting to query the subscription status information of the mobile terminal, the core network queries the subscription status information of the mobile terminal according to the content in the message, and sends the queried handover status information of the mobile terminal to the home base station mode switching apparatus.

S205: Determine whether the received subscription status information meets the access requirement of the new access mode. This step is the same as that of S3 and will not be described here. When the received subscription status information does not meet the access requirement of the new access mode, proceed to S206.

S206: Switch the mobile terminal out of the home base station or stop the service. Yet another embodiment:

In the above embodiment, the switching process is performed when the current access mode is the open mode and the new access mode is the closed mode for some systems that do not have the home base station gateway. For the system with the home base station gateway, when the subscription mode information of the mobile terminal is obtained, the message of requesting to query the subscription status information of the mobile terminal can be sent to the core network, and the information about the subscription status information of the mobile terminal can be sent to the core network. Sending a message to the home base station gateway to query the subscription status information of the mobile terminal.

FIG. 6 is still another flowchart of a method for switching a home base station mode according to another embodiment of the present invention.

S301: Obtain a new access mode.

S302: Determine an access requirement corresponding to the new access mode.

S303: Send a message requesting to query the subscription status information of the mobile terminal to the home base station gateway or the core network.

As shown in FIG. 3, in another embodiment of the present invention, a message for requesting to query for subscription status information of a mobile terminal is sent to a home base station gateway or a core network, specifically: S3031: Determine whether the mobile terminal currently accessing the home base station has the capability of closing the subscription group.

If the mobile terminal reports the capability of the closed subscriber group when the mobile terminal accesses the home base station, if the mobile terminal reports the indication information, the mobile terminal has the capability of closing the subscription user group; If the terminal does not report the indication information, it indicates that the mobile terminal does not have the capability of closing the subscriber group; and after receiving the indication information reported by the mobile terminal, the home base station stores the indication information in the home base station, so it is determined whether the mobile terminal is When the capability of the closed subscriber group is closed, it is determined by the indication information stored in the home base station.

By judging the closed subscriber group capability of the mobile terminal, it can be known whether to send a message requesting to query the subscription status information of the mobile terminal to the home base station gateway or the core network.

When the mobile terminal has the capability of closing the subscription group, S3032 is performed; when the mobile terminal does not have the capability of closing the subscription group, S3033 is performed.

S3032: Send a message to the core network requesting to query the subscription status information of the mobile terminal. In this step, the subscription status information of the mobile terminal is queried by the core network.

3033: Send a message to the home base station gateway requesting to query the subscription status information of the mobile terminal. In this step, the home base station gateway queries the subscription status information of the mobile terminal.

S304: Receive subscription status information of the mobile terminal sent by the home base station gateway or the core network. After receiving the message requesting to query the subscription status information of the mobile terminal, the home base station gateway or the core network queries the subscription status information of the mobile terminal, and sends the queried subscription status information of the mobile terminal to the home base station mode switching apparatus.

S305: Determine whether the received subscription status information meets the access requirement of the new access mode. This step is the same as that of S3 and will not be described here. When the received subscription status information does not meet the access requirement of the new access mode, proceed to S306.

S306: Switch the mobile terminal out of the home base station or stop the service.

In the embodiment S304 of the present invention, the home base station gateway or the core may be used through a dedicated channel. The network sends a message requesting to query the subscription status information of the mobile terminal, because when the mobile terminal accesses the home base station, at the link layer, each mobile terminal has its dedicated channel, that is, the mobile terminal and the dedicated channel are bound to each other. Through the dedicated channel transmission, the home base station gateway or the core network can query the subscription status information of the mobile terminal corresponding to the dedicated channel.

In addition, in other embodiments of the application, in S304, the dedicated channel may not be used, and the message requesting to query the subscription status information of the mobile terminal carries the identifier of the mobile terminal, so that when the home base station gateway or the core network receives After the message, according to the identifier of the mobile terminal carried by the mobile terminal, the subscription status information of the mobile terminal corresponding to the identifier of the mobile terminal can be queried. Yet another embodiment:

In the foregoing several embodiments, in the process of switching between the home base station modes, all the mobile terminals that are currently accessing the home base station are performed in the home base station except for accessing the mobile station. In addition to the terminal, there is also a mobile terminal residing in the home base station. For the mobile terminal residing in the home base station, when the home base station mode is switched, it also needs to be processed, otherwise the mobile station staying in the home base station moves. The terminal may also experience the problem of dropped the network after the home base station mode is switched.
