Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] An embodiment of the present invention provides a method for maintaining a bearer during the handover of a user equipment from a non-3rd Generation Partnership Project Non-3GPP access network to a 3GPP access network, such as figure 2 Shown:

[0027] In step 201, the new bearer ID assigned by the mobile management entity MME and the old bearer ID assigned by the original serving gateway SGW when accessing the 3GPP core network through the Non-3GPP access network are unified;

[0028] In step 202, the bearer is maintained according to the unified bearer ID.

[0029] It should be noted that in the 3GPP evolved network, the EPS bearer ID (Evolved Packet System bearer ID) is used to identify the end-to-end bearer. The so-called end-to-end b...

Abstract

The embodiment of the invention discloses a method for maintaining loading. According to the method, when user equipment is switched to a 3GPP access network from a non-third generation partner planned (Non-3GPP) access network, a new loading ID allocated through a uniform mobile management entity (MME) and a former loading ID allocated through a former service gateway (SGW) when the Non-3GPP access network is accessed to a 3GPP core network ensure that loading maintenance and use can be carried out according to a uniform loading ID; therefore, problems including update loading failure and network switching failure caused by different loading IDs allocated when user equipment is switched to the 3GPP access network from the Non-3GPP access network can be avoided. The invention also discloses a device and a system for maintaining loading.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, device and system for maintaining bearer. Background technique [0002] Both 3GPP (Third Generation Partnership Project) access network technology and Non-3GPP access network technology (non-3GPP access network technology) can be connected to the 3GPP core network. When the Non-3GPP access network is connected to the 3GPP core network, a GTP (General Packet Radio Service Tunneling Protocol) is established between the SGW (Serving Gateway) and the PGW (Packet Data Network Gateway). Service Tunneling Protocol) tunnel to carry the service, and the SGW allocates the GTP bearer ID (Identifier identifier). [0003] Figure 1a Shown is a simplified diagram of the evolved network architecture using 3GPP access technology in the prior art: EUTRAN (Evolved Universal Mobile Telecommunication System Terrestrial Radio AccessNetwork evolved UMTS Terrestrial Radio Access N...
