detailed description

The present invention will be further described in detail below with reference to the accompanying drawings. FIG. 1 is a flowchart of Embodiment 1 of a method for network sharing of a home base station according to an embodiment of the present invention, including:

Step 101: The home base station sends a public land mobile phone network list; the list is composed of public land mobile phone network information supported by the home base station; the specific public land mobile phone network information may be a public land mobile phone network identifier (PLMN ID), and the public The terrestrial mobile telephone network serial number and the like uniquely identify the identification information of the public land mobile telephone network.

When supporting the network sharing, the home base station can store the information of the public land mobile telephone network supported by the home base station, that is, the information of the public land mobile telephone network reachable by the home base station through the home base station gateway, and the public land in the list of the public land mobile telephone network. The mobile phone network is supported by the home base station;

Since the user land device supporting the network sharing can be parsed in the public land mobile phone network list, in order to be compatible with the user equipment that does not support the network sharing, an ordinary public land mobile phone network for selecting the user equipment that does not support the network sharing may also be transmitted ( Common PLMN ) information;

Since the user equipment that does not support network sharing cannot identify the list of public land mobile telephone networks broadcast by the home base station, only the ordinary public land mobile telephone network broadcasted in the conventional network can be identified, and the general public land mobile telephone network is a public land mobile supported by the home base station. In one of the telephone networks, the home base station can broadcast the above public land mobile telephone network list and the general public land mobile telephone network information by broadcasting.

Step 102: The home base station receives information from the user equipment, where the information of the user equipment includes public land mobile telephone network information selected by the user equipment;

The information from the user equipment may be a non-access stratum such as an attach request and a location area update.

(NAS: Non Access Stratum) news.

The public land mobile telephone network information selected by the user equipment corresponds to the public land mobile telephone network information in the public land mobile telephone network list sent by the home base station, and may be the public land mobile telephone network unique identifier public land mobile telephone network identifier, or may be Corresponding serial numbers in the list of public land mobile telephone networks;

After receiving the public land mobile phone network list, the user equipment will perform network selection. If it is a user equipment supporting network sharing, a public land mobile phone network will be selected from the public land mobile phone network list instead of the general public. The land mobile telephone network serves as an optional public land mobile telephone network and will select its own supported public land mobile telephone network from the list of public land mobile telephone networks. If it is a user equipment that does not support network sharing, the public land mobile telephone network list will not be parsed, and only the general public land mobile telephone network will be used as an optional public land mobile telephone network. The user equipment determines to access in the cell by cell selection or cell selection criterion, and the user equipment supporting the network sharing sends the public land mobile telephone network information selected by the user to the home base station. Specifically, the user equipment may be sent to the home base station by using an initial direct transmission message, or may be sent to the home base station by using other messages. Further, the initial direct transmission message may further include an attach request (Attach Request) of the non-access layer, where Messages such as Location Update. User equipment that does not support network sharing does not carry relevant public land mobile telephone network information in the initial direct transmission message;

Step 103: The home base station sends a message including public land mobile phone network information selected by the user equipment;

Specifically, when the user equipment supports network sharing, the sent message includes the public land mobile phone network information in the public land mobile phone network list selected by the user equipment; if the user equipment does not support the network sharing, the user equipment is initially straight. The message will not carry relevant information, so the home base station will send a message including the indication that the user equipment does not support the network sharing at this time, and the indication that the user equipment does not support the network sharing can trigger the home base station gateway or the public land mobile phone network. a node, such as a Mobile Switching Centre Server (MSC), a Serving General Packet Radio Service Support Node (SGSN), and the like, which perform processing processes that do not support shared user equipment;

The message including the public land mobile phone network information in the public land mobile phone network list or the indication that the user equipment does not support the network sharing may be an initial user equipment message, and the initial user equipment message includes, in addition to the public land mobile phone network information, Information such as non-access stratum messages (eg, attach request, location area update) may also be included.

As can be seen from the above, this embodiment can transmit a public land mobile telephone network list to the user equipment, so that the user equipment can select the public land mobile telephone network from the public land mobile telephone network list, and the home base station can select the public land of the user equipment. The mobile phone network information is sent out, for example, to the home base station gateway, the mobile switching center server, etc., so that the home base station gateway can send the attach request to the corresponding public land mobile phone network according to the public land mobile phone network information selected by the user equipment. The home base station supports network sharing, so that users of different operators can share one home base station, which can not only improve the resource utilization rate of the home base station, but also reduce the deployment cost of the home base station. Contribute to the promotion of home base stations.

2 is a flowchart of Embodiment 2 of a method for network sharing of a home base station according to an embodiment of the present invention, including:

Step 201: The home base station gateway receives an initial user equipment message.

The initial user equipment message may be sent by the home base station;

Step 202: The home base station gateway determines whether the initial user equipment message includes the public land mobile phone network information; if yes, proceeds to step 203; if not, proceeds to step 205;

Wherein, if the initial user equipment message includes public land mobile telephone network information in the public land mobile telephone network list, the user equipment supports network sharing, if the public land mobile telephone network information in the public land mobile telephone network list is not included, The user equipment does not support network sharing. In this case, the initial user equipment message includes an indication that the user equipment does not support network sharing.

Step 203: The home base station gateway selects routing information corresponding to the public land mobile phone network information from the pre-stored routing information.

The home base station gateway pre-stores the routing information of the nodes in each public land mobile telephone network. When the public land mobile telephone network information is included in the initial user equipment message, the public land mobile telephone network information included in the initial user equipment message may be used. Find the corresponding routing information from the saved routing information.

Step 204: The home base station gateway sends an initial user equipment message according to the routing information corresponding to the public land mobile phone network information, and ends the process;

After finding the corresponding routing information, the initial user equipment message may be sent according to the routing information, and the initial user equipment message is routed to a node in the corresponding public land mobile telephone network, such as a mobile switching center server, a service general packet radio service support node. And so that the node in the public land mobile phone network can perform an authentication operation, and after the authentication, send an attach response to the user equipment, where the attach response includes an indication of allowing the user equipment to access or an indication that the user equipment is not allowed to access.

Step 205: The home base station gateway adds a redirection indication to the received initial user equipment message, and sends an initial user equipment message with a redirection indication added to the public land mobile telephone network reachable by the home base station gateway;

After the home base station gateway learns that the user equipment does not support network sharing, the home base station gateway adds a redirection indication to the initial user equipment message, indicating that the public land mobile telephone network receives the redirection indication. The node can send a redirect command when the user equipment is not allowed to access, so that the home base station gateway can send an initial user equipment message to a node in another public land mobile telephone network. The public land mobile telephone network reachable by the home base station gateway refers to a public land mobile telephone network in which the home base station gateway can store corresponding routing information, and the home base station gateway can communicate; the home base station gateway can move from a public land that is reachable The telephone network sends an initial user equipment message with an increased redirection indication, and may also simultaneously send an initial user equipment message with a redirection indication added to a plurality of reachable public land mobile telephone networks.

Therefore, after the home base station gateway sends the initial user equipment message with the redirection indication added to the reachable public land mobile telephone network, the method further includes:

Receiving a redirect command or a redirect completion indication from the reachable public land mobile telephone network; the home base station gateway receives the redirect completion indication, indicating that the public land mobile telephone network selection process of the user equipment is completed, and the home base station gateway will carry The attach response indicated by the redirect completion is transmitted to the home base station, and the home base station sends the attach response to the user equipment.

The home base station gateway receives the redirection command, indicating that the public land mobile telephone network that sends the redirection command does not allow the user equipment to access; at this time, the home base station gateway can provide the reachable another public land mobile telephone network according to the saved routing information. Send an initial user equipment message with a redirect indication added.

Wherein, since the user equipment may eventually fail to access all public land mobile telephone networks reachable by the home base station gateway, the home base station gateway may further include: after receiving the redirection command from the reachable public land mobile telephone network:

Recording the reason for denying the user equipment access included in the redirection command; specifically, the reason for denying the user equipment access may be that the public land mobile telephone network is not allowed, the location area is not allowed, the location area roaming is not allowed, and there is no suitable cell In the location area, the public land mobile telephone network does not support General Packet Radio Service (GPRS: General Packet Radio Service);

If the home base station gateway has sent the initial user equipment message to all public land mobile telephone networks that are reachable, the user equipment access denied may be selected from the reasons of the denied user equipment access. Cause; and the reason for rejecting the user equipment access is sent to the user equipment.

The preset requirement may be that the reason for rejecting is the lightest, or the other way of rejecting the reason for the rejection, but the embodiment of the present invention preferably selects the lightest reason for rejection, for example, in the above-mentioned rejection user setting. The lightest of the reasons for standby access is that the public land mobile telephone network does not support general wireless packet services.

After the home base station gateway sends the initial user equipment message to the public land mobile telephone network, the node in the public land mobile telephone network authenticates the user equipment, and the authentication is generally performed by an identifier that uniquely identifies the user equipment, and the identifier may be User equipment's International Mobile Subscriber Identity (IMSI: International Mobile Subscriber Identity), user equipment serial number, etc.

Therefore, in order to speed up the authentication of the user equipment by the public land mobile phone network, when the identity of the user equipment is included in the redirect command, the identifier of the user equipment is added to the initial user equipment message, and the identifier of the user equipment is added. The initial user equipment message is sent to the reachable public land mobile telephone network, so that the public land mobile telephone network does not need to obtain the identity of the user equipment again when authenticating the user equipment.

As can be seen from the above, the home base station gateway in this embodiment can receive the initial user equipment message from the home base station and the public land mobile telephone network information selected by the user equipment, and thus the home base station gateway can select the public land mobile telephone network according to the user equipment. The information sends the attach request to the corresponding public land mobile phone network, so that the home base station supports the network share, so that users of different operators can share one home base station, which can reduce the deployment cost of the home base station and facilitate the promotion of the home base station; Further, the home base station gateway in this embodiment has a certain convergence effect on the traffic of the home base station, so that the pressure of the core network can be reduced, and the network sharing of the home base station can be realized without modifying the existing core network; The routing information maintained by the home base station to each public land mobile telephone network is such that the home base station does not need to maintain routing information to each public land mobile telephone network, which simplifies the implementation of the home base station.

As shown in FIG. 3, the network architecture of the home base station network architecture provided by the embodiment of the present invention may be referred to as a multi-operator core network (MOCN) network architecture, and the home base station gateway is used in the network architecture.

A node in the network.

The public land mobile phone network information selected by the user equipment may also be included in the initial user equipment message, so that the node of the public land mobile telephone network can determine whether the initial user equipment message is sent to the user after receiving the initial user equipment message. of.

The home base station gateway needs to have the ability to parse the initial user equipment message. Correspondingly, if there is another interface between the home base station gateway and the home base station, the home base station gateway also needs to have the ability to parse the corresponding interface message. The Iu interface is a system interface that can be connected to the universal mobile information system radio access network and the core network.

Step 407: The node of the public land mobile telephone network determines whether to accept the attachment request of the user equipment.

Step 408: The node of the public land mobile telephone network sends an attach response to the user equipment.

If the user equipment is allowed to access, an indication of allowing the user equipment to access is included in the attach response; if the user equipment is not allowed to access, an indication that the user equipment is not allowed to be accessed is included in the attach response. The public land mobile telephone network may directly send the attach response to the user equipment, or may send the user equipment to the user equipment through the home base station and the home base station gateway.
