The present invention discloses a method for a core network to obtain user access information during a handover procedure, which includes: when the user handovers between HNBs or HeNBs and the core network does not carry out access control of the user, if the destination HeNB is connected to the core network directly or the user which does not support a closed subscriber group handovers to a hybrid destination HNB, the network element which controls the access of the user transmitting membership information of the user to the core network. The invention also discloses a corresponding system. The invention realizes that under the condition that the RAN side controlling the access of the UE during the handover process and the CN cannot know the membership of the UE, the RAN side notifying the core network of the membership information of the UE and the information of the H(e)NB.

Systems and methods for obtaining subscriber access information by a core network in a handover process

An embodiment of the present invention provides a method for transmitting Closed Subscriber Group (CSG) information, which comprises: after receiving a message for requesting the CSG information, a target network element with a CSG attribute returning its own CSG information at least containing CSG Identitfier (ID) information of a CSG to which the target network element belongs to a source network element which initiates the message. The method and eNBs for transmitting CSG information in accordance with the embodiment of the present invention may allow the eNBs to obtain the CSG information of each other, so as to ensure that a direct interface can be set up between HeNBs with the same CSG attribute under the same HeNB GW.

Method and base station for transmitting closed subscriber group information

The disclosure provides a method and a system for implementing a direct interface between access network nodes. The method includes: establishing, by an access network node, a direct interface with a proxy node (); exchanging, by the access network node, information with an access network node managed by the proxy node through the established direct interface (). By establishing a direct interface between access network nodes and performing a direct interface flow through a proxy node, the disclosure simplifies the establishment and maintenance of the direct interface on the premise that the handover speed is increased and the signaling load of a core network is decreased, thereby reducing the complexity of the establishment and maintenance of the direct interface.

Method and system for implementing direct interface between access network nodes

The disclosure provides a method for notifying update information to a Core Network (CN), the method includes: a target access network element sends Close Subscriber Group (CSG) information of a cell that a User Equipment (UE) currently accesses to the CN after the UE is handed over from a source access network element to the target access network element; or the UE sends the CSG information of the cell that the UE currently accesses to the CN after receiving an instruction from the target access network element. According to the technical solution of the disclosure, when the CN does not participate in the handover process, the CSG information of the cell that the UE currently accesses is notified to the CN.

Method and system for notifying update information to core network

The present invention discloses a method for information transmission, the method including: in a process of a terminal initial accessing and/or the terminal handing over, an upper level access node belonging to a hierarchical architecture access network notifying a final access node belonging to the same hierarchical architecture access network of information of a mobility management entity (MME) to which the terminal accesses. The present invention also discloses an access node. The present invention makes the final access node acquire the information of the MME to which the terminal accesses so that the final access node can perform X2 handover via the acquired information of the MME.

Method and access node for transmitting information

The present invention provides a method for processing terminal membership based on a hybrid access mode cell, which method comprises: when the CSG member state of a terminal changes to a new CSG member state, a core network or a HNB gateway informing an access network element of the information about the new CSG member state; and the access network element processing the terminal according to information about the new CSG member state. The present invention further provides a system for processing terminal membership based on a hybrid access mode cell. In the present invention, when the subscription information changes when a terminal is in the connected state, not only the subscription information stored in the terminal and the core network or the HNB gateway is changed, but also the access network element which it accesses modifies its access identity to be a new CSG member state, thus the non-subscribed users and the subscribers can be processed differently and accurately.

Method and system for processing terminal membership based on hybrid access mode cell

A Method and a system for a Home NodeB (HNB) of Hybrid Access Mode to obtain the access mode of a User Equipment (UE) are provided by the present disclosure. During the registering process of the UE, a Home NodeB Gateway (HNB GW) determines the access membership of the UE according to the capability, the register reason of the UE and the access mode of the HNB itself, and transmits the access mode of the UE to the HNB. The method of the present disclosure enables the HNB of Hybrid Access Mode to differentiate subscribers from non-subscribers, therefore ensuing that users of different memberships (Close/Open) are processed differently, so that HNB can realize indeed to process services of different UEs corresponding to different Quality of Service (QoSes).
