Problems solved by technology

[0023] Through the above process, the bearer between UE and PGW can be established when the SGSN is the SGSN of 3GPP version 7 or earlier. However, since the SGSN of 3GPP version 8 is connected to the PGW through the SGW, the existing bearer establishment scheme does not It canno

Example Embodiment

[0084] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0085] The embodiment of the bearer establishment method provided by the present invention is the same as image 3 Shown, including:

[0086] Step 301: The PGW obtains the first QoS information and the first bearer identifier, and establishes a bearer with the RAN according to the first QoS information, and the bearer corresponds to the first bearer identifier;

[0087] The PGW can directly establish the bearer with the RAN, or forward the data between the PGW and the RAN through the SGW and / or SGSN when establishing the bearer with the RAN. The specific cases are as follows: (1) PGW establishment and The first bearer between SGW, SGW establishes a bearer with RAN, and SGSN only forwards data between SGW and RAN; (2) PGW establishes a bearer with S...

Abstract

The invention relates to the technical field of communication, and discloses a bearer establishment method and a related device, wherein, the bearer establishment method comprises the following steps: a PGW obtains a first QoS message and a first bearer identification, and establishes a bearer with an RAN according to the first QoS message, and the bearer is corresponding to the first bearer identification; and the RAN establishes a wireless bearer with a UE according to a second QoS message corresponding to the first QoS message, and the wireless bearer is corresponding to a second bearer identification which is corresponding to the first bearer identification. By using the technical scheme provided by the invention, the bearer between the UE and the PGW can be established by an SGSN and an SGW when the UE is accessed to the SGW via the SGSN, which causes full utilization of resources of various network entities in a network.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a bearer establishment method and a related device. Background technique [0002] Currently in the Third Generation Partnership Project (3GPP: Third Generation Partnership Project), the concept of Long Term Evolved Network / System Architecture Evolved Network (LTE / SAE: Long Term Evolved / System Architecture Evolved) is proposed. The purpose of LTE is to provide a A network that can reduce delay, increase user data rate, improve system capacity, and cover low cost. For the convenience of description, the SAE network architecture is simplified and can be divided into two parts, such as figure 1 Shown: [0003] The first part: User Equipment (UE: User Equipment) 101, Radio Access Network (RAN: Radio Access Network) 102, Serving General Packet Radio Service Support Node (SGSN: Serving General Packet Radio Service Support Node) 103, Packet Data Network Gateway ( PGW...
