Abstract

The present invention discloses three negotiation methods of a compression algorithm in the separation structure of control plane and user plane. In the first method, a user terminal sends compression algorithm processing information to a user plane network element; according to the owned compression algorithm processing information and the compression algorithm processing information of the user terminal, the user plane network element obtains the compression algorithm by negotiation, and the compression algorithm is then sent to a control plane network element and the user terminal. In the second method, the user terminal and the user plane network element respectively send respective compression algorithm processing information to the control plane network element, the control plane network element obtains the compression algorithm by negotiation, and the compression algorithm is respectively sent to the user terminal and the user plane network element. In the third method, the user plane network element sends the owned compression algorithm processing information to the user terminal; according to the owned compression algorithm processing information and the compression algorithm processing information of the user plane network element, the user terminal obtains the compression algorithm by negotiation, and the compression algorithm is sent to the user plane network element and the control plane network element. The present invention realizes a compression algorithm negotiation process in the separation structure of contol plane and user plane.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for negotiating a compression algorithm and a system thereof under a structure in which a control plane and a user plane are separated. Background technique [0002] In order to enhance the competitiveness of future networks, 3GPP is studying a new evolved network architecture, including System Architecture Evolution (SAE) and Long Term Evolution (LTE) of the access network. [0003] see figure 1 , is a schematic diagram of the architecture of the evolved network. Among them, the evolved access network is called the evolved UMTS terrestrial radio access network (E-UTRAN), and the evolved packet core network includes a mobility management entity (Mobility Management Entity, MME), a user plane entity (User Plane Entity, UPE) ) and the user plane anchor (IASA Inter Access System Anchor) logical functional entity between different access systems. [0004] The MME is responsi...
