Embodiment Construction

[0039] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0040] In the embodiment of the present invention, the control plane function and the forwarding plane function of the Serving Gateway (SGW, Serving GateWay) and the Packet Data Network Gateway (PGW, Packet Data Network GateWay) in the communication system are separated. Two types of interfaces are added to the separated network, that is, the connection interface between the control plane and the forwarding plane of the SGW, and the connection interface between the forwarding plane and the forwarding plane of the PGW. Based on this idea, the embodiment of the present inven...

Abstract

The invention discloses a user equipment initial attachment method and system. Under the configuration of the separated control plane function and forwarding plane (user plane) function of a SGW and a PGW, the method includes an MME sends a session creation request to the SGW-C after receiving an attachment request from the UE; the SGW-C establishes the session between the SGW-C and the SGW-U according to the attachment request; the SGW-C sends a session creation request to the PGW-C; the PGW-C establishes the IP-CAN session connection with the PCRF after receiving the session creation request; the PGW-C distributes an IP address for the UE; the PGW-C establishes a session with the PGW-U and sends a session creation response to the SGW-C; the SGW-C forwards the session creation response to the MME; MME determines the session establishment with the UE via eNodeB; and the eNodeB sends the TEID of the eNodeB and the IP address information of the eNodeB to the SGW-U via the MME and the SGW-C, so that the data transmisson channel of the forwarding plane is opened up.

Description

technical field [0001] The present invention relates to attachment technology, in particular to a method and system for initial attachment of user equipment (UE, User Equipment) after gateway controls forwarding separation. Background technique [0002] In the current Long Term Evolution (LTE, Long Term Evolution) / Evolved Packet Core (EPC, Evolved Packet Core) architecture, the EPC gateway device not only includes routing and forwarding functions, but also includes related functions of signaling processing and even service processing. Functions are tightly coupled, and the communication between them depends on the internal implementation. The high coupling between the control plane and the forwarding plane of gateway devices leads to long device update cycles and increased composite costs, which is very unfavorable for the smooth evolution of the core network. [0003] Unfortunately, there is currently no solution available for reference. Contents of the invention [000...
