Patent number: 9560048Abstract: A method for updating identity information of a packet gateway, an authentication, authorization, and accounting (AAA) server and a packet gateway. The method includes: a decision-making network element receiving a message which carries user equipment (UE) capability indication information and is sent by an information transmission network element; the decision-making network element deciding whether to update identity information of the packet gateway or not according to the UE capability indication information carried in the message and/or local information. The technical solution can be applied to distinguish R11 UE and R12 UE, and to ensure supporting both the R11 UE and the R12 UE normally accessing to a 3GPP core network through a 3GPP access system and a non-3GPP access system simultaneously.Type: GrantFiled: May 13, 2013Date of Patent: January 31, 2017Assignee: ZTE CorporationInventors: Guoyan Liu, Chunhui Zhu

Patent number: 9516681Abstract: A method, device and system for accessing a core network by means of non-3rd Generation Partnership Project (3GPP) access are disclosed, so as to acquire capability information of a User Equipment (UE) and/or capability information of a non-3GPP access system, and decide, according to the acquired capability information, whether the UE transfers information required for establishing an Evolved Packet Core (EPC) session. The disclosure can enhance the capability of the UE to support establishment of an extra Packet Data Network (PDN) connection and service continuity during switching between access systems. Meanwhile, the capability of a peer can be acquired through the UE and a network, so that the network may support normal access by an existing UE and an enhanced UE simultaneously.Type: GrantFiled: December 21, 2012Date of Patent: December 6, 2016Assignee: ZTE CORPORATIONInventors: Guoyan Liu, Chunhui Zhu, Shuang Liang

Patent number: 9467962Abstract: A trusted non-3GPP access network element and a method for accessing a mobile network and detachment are disclosed. The method for accessing a mobile network includes: a TNAN network element receives an extensible authentication protocol (EAP) authentication success message or an EAP authentication success triggering message, and then establishes a session with a packet data network gateway (P-GW) of a mobile network; and the TNAN network element receives an IP address request message from user equipment and then allocates an IP address consistent with the packet data network (PDN) type requested by the user equipment to the user equipment.Type: GrantFiled: September 21, 2012Date of Patent: October 11, 2016Assignee: ZTE CorporationInventors: Guoyan Liu, Chunhui Zhu, Shuang Liang, Yangwei Tu

Patent number: 9456006Abstract: Disclosed are a method, device and system for session binding. The method includes: a PCRF or BPCF receives a first session from a fixed network, wherein the first session carries an IP address and a port number set; the PCRF or BPCF receives a second session from an AF or a Traffic Detection Function (TDF), wherein the second session carries an IP address and port number information; and the PCRF or BPCF binds the first session to the second session according to the IP addresses and the port number information. The disclosure solves the problem of inaccurate session binding in the scenario where a mobile terminal directly accesses mobile network services via a fixed network.Type: GrantFiled: June 18, 2012Date of Patent: September 27, 2016Assignee: ZTE CORPORATIONInventors: Yifeng Bi, Guoyan Liu, Zaifeng Zong, Xiaoyun Zhou

Publication number: 20160212597Abstract: Provided are a method for optimizing the multicast group and an anchor. A set of nodes requesting for the same multicast group data and sharing the same Access Gateway (AG) is identified in a multicast group, and the same multicast group data is transmitted to each node in the set of nodes via the same AG thereby forwarding multicast data to different nodes via the same gateway, saving traffic of a network side, and optimizing the multicast group. In addition, the node optimization method allows the anchor to optimize multicast routing of the nodes requesting for the same multicast group data and sharing the same AG to the same shared gateway for forwarding if a node has a plurality of access interfaces in the present application.Type: ApplicationFiled: June 11, 2014Publication date: July 21, 2016Inventors: Yong CUI, Yan LIU, Xin XU, Wendong WANG, Guoyan LIU, Min SHEN, Na ZHOU, Chunhui ZHU

Publication number: 20150296445Abstract: A method, device and system for managing a packet data network type management are disclosed. The method comprises: a User Equipment, UE, sends a request message to a WLAN AN, wherein the request message carries a packet data network type requested by the UE; the UE receives an acknowledgement message returned by the WLAN AN to the UE, wherein the acknowledgement message carries a packet data network type decided by a network side. It is solved the technical problem in the related art of the waste of the address resources, which is caused by the fact that the addresses corresponding to the packet data network type subscribed by the user in the subscription information are all directly allocated to the UE in advance, thereby achieving the technical effects of reducing the wasted address resources and improving the address resource utilization rate.Type: ApplicationFiled: October 24, 2013Publication date: October 15, 2015Inventors: Xingyue ZHOU, Guoyan LIU, Chunhui ZHU

Patent number: 9119114Abstract: The present disclosure discloses a method and system for updating tunnel information. The method comprises: a target HeNB which a user equipment (UE) is to be handed over notifies a Mobility Management Entity (MME) of the tunnel information through a handover acknowledgement message, a handover notification message or a path converting request message; and the MME notifies a fixed network of the received tunnel information through an Evolved Packet Core (EPC) gateway and a Policy and Charging Rules Function entity (PCRF). With the present disclosure, policy interworking between a mobile network and the fixed network can be implemented, and the Quality of Service of the HeNB can be ensured.Type: GrantFiled: February 16, 2012Date of Patent: August 25, 2015Assignee: ZTE CorporationInventors: Yifeng Bi, Guoyan Liu
