The present invention relates to the field of communications technologies, and in particular, to a home base station function configuration method, a home base station, and a communication system. Background technique

With the rapid increase in the number of mobile communication users and the increasing user demand, the concept of home base station and home access has been introduced in mobile communication systems. The home base station is a miniaturized base station that is deployed as a dedicated resource in the home. Used by groups, companies, or schools to serve specific users. The home base station can be set to allow only certain user terminals with private network rights to camp or access, and these user terminals can also reside or access in the public network. The home access mode is a new access mode. The user equipment first accesses the home base station, and the home base station can access the core network through the home base station gateway.

The home base station itself can support multiple functions such as a non-access stratum node selection function (NNSF, NAS Node Selection Function), a local route (LBO, Local Breakout), and the like. In the prior art, the opening or closing of these functions is first configured on the home base station, or is configured according to the initiation process of the user equipment (UE, User Equipment). The possible problems with this method are: In some cases, the home base station turns on unnecessary functions, resulting in an invalid process, increasing signaling interaction; or, in some cases, because the home base station is not turned on. The required function causes the system to be abnormal.

The basic architecture of the home access system in the embodiment of the present invention is as shown in FIG. 1. The user equipment 110 accesses the core network 130 through the home base station access network 120. The home base station access network may include the home base station 121 and the home base station. Gateway 122. The home base station gateway 122 acts as a sink node for the home base station and is responsible for forwarding signaling and data between the home base station 121 and the network elements in the core network 130.

A method for configuring a home base station function according to an embodiment of the present invention is described below. Referring to FIG. 2, the method includes:

S201. The home base station receives the function configuration indication information sent by the network management device.

S202. The home base station configures its own function according to the function configuration indication information. The network management device may be a home base station management system (HMS, HeNB Management System), or a home base station gateway or a core network side mobility management entity, for example, a serving GPRS support node SGSN, E in a URTAN network. - mobility in the URTAN network Management entity MME, etc.

The foregoing function configuration indication information may include: a non-access stratum node selection function (NNSF, NAS Node Selection Function).

The function of the NNSF is to select the NAS node that provides the network service for the UE. The executor of the NNSF is different according to the registration target node of the home base station: If the target node registered by the home base station is the home base station gateway, the NNSF function is provided by the home base station gateway. Executing; If the target node registered by the home base station is a management node on the core network side, for example, the mobility management entity MME in the E-URTAN network, the NSF function is performed by the home base station.

In the prior art, whether the home base station enables the NNSF function is pre-configured in the home base station. In this way, when the registration target node of the home base station is the home base station gateway, if the NNSF function is enabled, an unnecessary NAS node selection process will be caused; otherwise, when the registration target node of the home base station is the management node of the core network side, If the NNSF function is not enabled on the home base station, the functional entity of the NAS node is not selected for the UE, causing the system to be abnormal.

As the network management device knows the registration target node of each home base station, in the embodiment of the present invention, the network management device may indicate, in the function configuration indication information, whether the home base station starts the NNSF function, and the home base station according to the indication of the network management device , NNSF function can be turned on or off correctly, avoiding unnecessary NAS node selection process or no entity executing NNSF.

The foregoing function configuration indication information may further include: LBO function configuration indication information.

In addition to accessing the core network through the home base station, the UE can also directly communicate with other devices in the home network through the home base station. In this case, a large amount of user data streams do not have to pass through the operator's bone network, and can be greatly reduced. Network load of small operators. Therefore, local routing of home base station user data includes two types: local routing of user data to the home network and local routing of users to the core network.

The home base station itself may have an LBO function, but whether the LBO service can be implemented on the home base station will depend on the subscription information of the home base station and the operator configuration policy. In the prior art, the local routing service is initiated by the UE. Since the UE does not know the subscription of the home base station and the network configuration policy of the operator, the home base station may still start the LBO without obtaining the subscription permission. The function, which leads to an invalid route configuration process, increases signaling interaction. According to the technical solution of the embodiment of the present invention, the network management device may indicate whether the home base station enables the LBO function according to the operator network configuration policy and/or the subscription status of the home base station, so as to prevent the court base station from still obtaining the subscription permission. Turning on the LBO function results in an invalid route configuration process. As shown in FIG. 3, before the network management device sends the function configuration indication information to the home base station, the method may further include:

S200. The home base station sends its own function information to the network management device.

By default, each home base station is considered to be fully functional. Therefore, the network management device only needs to instruct the home base station to configure the corresponding function according to the specific network configuration. However, in practical applications, some home base stations may not have certain functions. In this case, the home base station needs to first report its own function information to the network management device, and the network management device can combine each home base station. The specific function indicates that the home base station correctly configures the corresponding function, so as to prevent the network management device from initiating the function that the host base station does not support without knowing the specific function of the home base station. The technical solution of the present invention will be described below in conjunction with several specific embodiments.

Embodiment 1:

The present specification is described by taking an evolved UMTS terrestrial radio access network (E-UTRAN) as an example. Those skilled in the art should understand that the application scenario does not limit the present invention, and the present invention can also be applied to other similar scenarios. In the E-UTRAN network, the home base station is a Home Evolved NodeB (HeNB), the home base station gateway is a Home ENodeB Gateway (HeNB GW, Home eNodeB Gateway), and the management device on the core network side is a mobility management entity ( MME, Mobility Management Entity).

In this example, before the HeNB registers, the function of the HeNB is configured, as shown in FIG. 4, including the following steps:

S401. The HeNB initiates a gateway discovery request message (GW Discovery Request) to the HMS, and carries the function information of the HeNB, for example, whether the NNSF is supported, whether the LBO is supported, or the like. In the request message, it may further include other function information, such as a packet data network.

(PDN, Packet Data Network) information, packet data gateway (PGW, Packet Data Network Gateway) information, and the like. The PDN information may specifically include Internet information, home network information, and the like.

For the home base station, if the PDN information and the Z or PGW information can be obtained, the home base station is considered to have the LBO function; conversely, if the home base station cannot obtain the above information, it is considered that the home base station does not have the LBO function. Therefore, the PDN information or PGW information of the home base station can also be used instead of the LBO function information.

S402. The HMS returns a gateway discovery response message (GW Discovery Response) to the HeNB according to a configuration policy of the network system, for example, whether the local route, the HeNB subscription information, and/or the HeNB function information is allowed, and carries the function configuration in the response message. The indication information may include: an indication of whether to enable the NNSF, an indication of whether to enable the LBO, an indication of the LBO mode (eg, LBO to the Internet, LBO to the home network), and an indication of how the HeNB connects to the network (eg, : direct connection, indirect connection, etc.

S403. The HeNB performs function configuration according to the function configuration indication information in the gateway discovery response message, and starts or disables the corresponding function.

Optionally, after the HeNB completes the function configuration, the HeNB may continue to perform the subsequent registration process. The indication of whether to enable the NNSF may also be replaced by the indication that the HeNB is connected to the network mode. The connection mode of the HeNB includes a direct connection mode and an indirect connection mode. If it is a direct connection mode, the HeNB will directly register with the MME. In the function setting, the NNSF should be started accordingly. If it is the indirect connection mode, the HeNB will register with the HeNB GW, and the NNSF should be closed accordingly.

It should be noted that, in this embodiment, the function information of the HeNB and the function configuration indication information sent by the HMS are respectively carried in the gateway discovery request message and the gateway discovery response message. It will be understood by those skilled in the art that the above two kinds of information can also be carried in other types of request/response messages, respectively, which do not affect the implementation of the solution of the present invention.

In this embodiment, before the home base station performs registration, the HMS instructs the HeNB to perform function configuration, and the function configuration may be completed before the HeNB enables the wireless function. Ensure that the HeNB starts its supported functions under the control of the network, preventing the HeNB from initiating the network forbidden function and reducing invalidity. Signaling to improve the stability of the system. Embodiment 2:

In this embodiment, in the process of establishing a connection between the home base station and the core network, the function of the home base station is configured, as shown in FIG. 5, including the following steps:

S501: The HeNB initiates an S1 connection setup request message (SI Setup Request) to the MME or the HeNB GW, and carries the function information of the HeNB, for example, whether the NNSF is supported, whether the LBO is supported, or the like.

In the request message, other function information, such as packet data network (PDN, Packet Data Network) information, packet data gateway (PGW, Packet Data Network Gateway) information, and the like, may be further included. The PDN information may specifically include Internet information, home grid information, and the like.

5502, the MME or the HeNB GW returns a connection establishment response message (SI Setup Response) to the HeNB according to a configuration policy of the network system, such as: whether to allow local routing, HeNB subscription information, and/or function information of the HeNB, and in the response message The function configuration indication information may include: an indication of whether to enable the NNSF, an indication of whether to enable the LBO, and an indication of the LBO mode, such as an LBO to the Internet or an LBO to the home network.

S503. The HeNB starts or disables the corresponding function according to the function configuration indication information in the gateway discovery response message.

When the HMS is unable to instruct the HeNB to perform the function configuration, the MME or the HeNB GW may be carried in the S1 connection setup message in the process of establishing the connection between the home base station and the core network. Instructing the home base station to perform function configuration also ensures that the HeNB starts its supported functions under the control of the network, prevents the HeNB from initiating the network forbidden function, reduces invalid signaling, and improves system stability. The above combines two specific processes in the E-UTRAN network to explain the function configuration method of the home base station. It should be noted that the above two embodiments are only used for the schematic description, and those skilled in the art can easily think that the home base station technology can be applied to various types of mobile networks, and the home base station function configuration provided by the embodiments of the present invention is provided.

The function information may include: whether the NSSF is supported, whether the LBO or the like is supported.

After the home base station reports its own function information to the network management device, the network management device can, according to the specific function of each home base station, instruct the home base station to correctly configure the corresponding function, so as to prevent the network management device from knowing the specificity of the home base station. In the case of a function, the home base station is instructed to turn on a function that it does not support. The embodiment of the present invention further provides a communication system, as shown in FIG. 8, including a network management device 810 and a home base station 820.
