Embodiment Construction

[0030] In order to solve the problem of complex and cumbersome signaling procedures during the PDN connection handover process caused by the UE moving between the 3GPP network and the non-3GPP network or other reasons, the embodiment of the present invention proposes a PDN connection management solution. In the embodiment of the present invention, interactive management of PDN connections in multiple access networks can be realized on the PGW side or / and UE side, and the maintenance of the context of PDN connections in different access networks on the PGW side or / and UE side is supported, and Reduce the PDN connection handover process by marking the target access network as an active network and the source access network as an inactive network according to the handover situation of the PDN connection, and retaining the context of the source access network in the context of the PDN connection The complexity of signaling processing caused by establishing a PDN connection in the t...

Abstract

The invention discloses a PDN connection management method and equipment, and is used for simplifying a signaling process of switching between a 3GPP system and a non-3GPP system and reducing intersystem switching delay. In the PDN connection management method, in a second network attachment process launched by a terminal accessed to a first network, PDN gateway equipment establishes a PDN connection in the second network according to a PDN connection of the terminal that needs switching from the first network to the second network; the PDN connection established in the second network and the PDN connection in the first network that needs switching from the first network to the second network share PDN connection context; and according to the PDN connection established in the second network, the PDN gateway equipment adds second network context in the corresponding PDN connection context, and marks the first network as an unactivated network of the corresponding PDN connection and marks the second network as an activated network of the corresponding PDN connection in the corresponding PDN connection context.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a connection management method and equipment. Background technique [0002] At present, various schemes of interoperability between 3GPP (3rd Generation Partnership Project) networks and non-3GPP (non-3GPP) networks have been basically completed. [0003] In order to support better scalability, EPS (Evolved Packet System, Evolved Packet System) supports the access and interoperability of 3GPP network and non-3GPP network. At present, the trusted non-3GPP IP access network realizes interoperability with the 3GPP network through the s2a or s2c interface, and the non-trusted non-3GPP IP access network realizes interoperability with the 3GPP network through the s2c or s2b interface. [0004] In the existing solution, after the handover between the 3GPP network and the non-3GPP network is completed, the PGW (PDN Gateway, PDN Gateway) initiates the release of th...
