Problems solved by technology

However, in the existing general mobile network, the AP is only responsible for wireless access, and the session control is completed at the access gateway (AG, Access Gateway), which makes this direct connection scheme not applicable to general communication networks

Embodiment Construction

[0025] refer to figure 1 , figure 1 It is a schematic diagram of a specific application scenario of the embodiment of the present invention.

[0026] As shown in the figure, two users (UE, User Equipment): UE1 and UE2 are taken as an example for illustration. They establish a user plane connection through a normal call process, and the data transmission path is:

[0027] UE1AP1AGPDN-GWAGAP2UE2.

[0028] Since the communication data needs to pass through core network equipment such as PDN-GW and AG, the load on these equipment is increased; the existing technology requires the AP to have session control capabilities in order to establish a local connection between AP1 and AP2, which requires a large change to the existing network equipment , is not universal.

[0029] The embodiment of the invention discloses a method, device and system for realizing local transmission of communication data in a general communication network.

[0030] The embodiment of the present invention...

Abstract

The invention discloses a method, a system and a device for realizing local transmission. Whether a corresponding access device of communication service data satisfies a local transmission condition is judged, if the access device satisfies the local transmission condition, the access device is triggered to carry out the local transmission, consequently, communication date is locally transmitted in a universal communication network, device resources and transmission resources of the communication network are saved, the quantity and the reliability of the communication service transmission are strengthened, and thereby the satisfaction degree of users is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, system and equipment for realizing local transmission. Background technique [0002] The next-generation evolution goal of the mobile communication network is a flat two-layer network. The access network only includes one layer of access nodes, and the core network includes access-side gateways, service-side gateways, and mobile control nodes. The user's voice and data services are transmitted through the mobile network in the form of packets. [0003] The control of packet data transmission must be carried out through the core network gateway. With the development of mobile broadband, a large amount of data transmission will take place in the same access network. Under the current mobile service control mechanism, these data flows need to be uplinked from the access network to the core network, and then returned to the access network after transmission. It not only ...
