Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for performing access control judgment on a user in a connected state by a core network after an access mode of a base station is changed.
Background
The home base station is a small-sized and low-power base station, is deployed in indoor places such as homes, offices and the like, and mainly has the functions of providing higher service rate for users, reducing the cost required by using high-rate services and making up for the insufficient coverage of the existing distributed cellular wireless communication system. The home base station has the advantages of being economical, convenient, low-power output, plug-and-play, broadband access, single-mode terminal support and the like.
The home base station may be applied in a third Generation (3G) or Long Term Evolution (LTE) wireless communication network. In order to facilitate the management of the home base station, a new network element, namely a home base station gateway, is introduced into the radio access network. The home base station gateway mainly performs the following functions: the safety of the home base station is verified, the registration of the home base station is processed, the home base station is operated, maintained and managed, the home base station is configured and controlled according to the requirements of an operator, and the home base station is responsible for exchanging data information between a Core Network (CN) and a HeNB.
Fig. 1 is a schematic diagram of a 3G wireless network architecture including a femto, where as shown in fig. 1, the 3G femto is connected to a femto gateway through a newly defined Iuh interface, and the femto gateway provides the femto with an IuCs interface to a core network circuit domain and an IuPS interface to a core network packet domain. For a 3G wireless network, a home base station gateway is indispensable in deployment, and is used to shield the influence on User Equipment (UE) and a network side after the home base station is introduced; for the LTE wireless network, the femto-gateway is optional in deployment, so that in the LTE wireless network, there are two connection modes between the femto-gateway and the core network, one is that the femto-gateway is directly connected to a network element of the core network, as shown in fig. 2; the other is that the femto is connected to the network element of the core network through the femto gateway, as shown in fig. 3. In fig. 3, in the case of introducing the hnb gateway, the hnb gateway may not integrate the user plane function, and at this time, the hnb directly establishes a user plane connection with the user plane gateway of the core network, as shown in fig. 4, so that the user plane can be flattened and the data transmission delay can be reduced.
The access modes of the home base station are divided into a closed mode, a mixed mode and an open mode. Since the femto has a certain privacy as a user-level device, there is a restriction on subscription for users in different access modes. When the access mode of the home base station is a closed mode, only a subscriber of the home base station can access the base station and enjoy the service provided by the home base station; when the access mode of the home base station is an open mode, any user can access the home base station, and the home base station is equal to a macro base station; when the access mode of the femtocell is the hybrid mode, any user can access the femtocell, but different levels need to be distinguished according to whether the user signs a contract, that is, the signed user has higher service priority when using the femtocell with the hybrid mode, and can enjoy better service quality and service class.
The access control determination of whether to allow the user to use the hnb may be performed by the hnb gateway or may be performed by the mobility management entity of the core network, that is, the access control determination point may be at the hnb gateway or may be at the mobility management entity of the core network. The selection between the home base station gateway and the mobility management entity is made according to whether the UE has Closed Subscriber Group (CSG) capability and whether the core network supports the CSG concept. The selection and execution of the access control decision point will be briefly described below.
The CSG concept was proposed after the introduction of the home base station. Generally, a user in a home or an enterprise forms a closed subscriber group, and the closed subscriber group is distinguished and identified by a CSG identity (CSG ID); and the home base stations for providing service for the users in the closed subscriber group have the same CSG identification. The user can access home base stations corresponding to a plurality of closed user groups, such as an office and a home of the user, by signing with the operator. In this way, a concept is introduced that allows for a closed subscriber group List (ACL), which may be stored in the user's UE and the user data server on the network side.
If the UE of the user has CSG capability, that is, the UE can identify and read information such as CSG id, and the core network supports the CSG concept, that is, the core network supports ACL processing, then the access control determination point for the user corresponding to the UE is located in the mobility management entity. When the user initiates access, the mobility management entity performs access control judgment on the user by using the ACL issued by the user data server and combining the CSG identification and the access mode reported by the home base station.
If the UE of the user does not have the CSG capability or the core network does not support the CSG concept, the access control judgment point of the user corresponding to the UE is located at the home base station gateway. When the user initiates access, the home base station gateway performs access control judgment on the user by using the corresponding relation between the user identification stored in the home base station gateway or acquired by the configuration server and the home base station. The configuration server may be a database in the wireless network for storing user related information, such as a correspondence between user identities and home base stations.
If the access mode of the home base station is changed, certain influence exists on the user in the connection state at present. For example, if the access mode of the home base station is changed from the hybrid mode or the open mode to the closed mode, access control needs to be performed again for the currently connected user, and the non-subscribed user is released or handed over to another suitable cell.
When the core network supports the CSG concept and the access control determination points are different due to different CSG capabilities of the UE of the user, the specific process is as follows: the access mode of the home base station is changed from a mixed mode or an open mode to a closed mode, and the home base station can inform the home base station gateway and the mobility management entity of the changed access mode, namely the current access mode; the home base station gateway executes access control judgment on all the users which do not have CSG capability and are in a connected state by utilizing the corresponding relation between the user identification and the base station; although the mobility management entity can determine all users currently in a connected state through the home base station identifier reported by the home base station or all cell identifiers corresponding to the home base station, the mobility management entity cannot identify the CSG capability of the user, so that it is impossible to distinguish which users should be subjected to access control judgment again, and further conflict with the access control judgment of the home base station gateway or situations of missed judgment and erroneous judgment are generated.
