Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0048] First, various implementations of assigning the EPS bearer identity by the MME will be described.

[0049] The first embodiment relates to a method for assigning and transmitting a bearer identifier in an evolved network. A bearer is established when a UE attaches (Attach), and the process is as follows figure 2 As shown, the description of each step is as follows:

[0050] 1-11. The process steps of UE performing network attachment have nothing to do with the patent points of the present invention.

[0051] 12. The MME allocates the EPS bearer identity, and sends a bearer establishment request message to the Serving GW, the message carries the allocated EPS bearer identity, and the Serving GW stores the EPS bearer identity.

Abstract

The invention relates to the wireless communication field, discloses a method and a device for processing bearer identities and enables an EPS bearer to be established and used successfully. In the invention, bearer identities are allocated by MME, PDN GW, Serving GW, or UE; and well-allocated bearer identities are carried by messages in the establishing flow of the bearer and transmitted to each physical device related to the newly-built bearer. During the bearer establishing flow, the binding of related message can be realized through the related identities carried by the message and transmitted and received by certain physical devices. In the process of establishing a signaling messaged of non-first bearer for a PDN, the carried related bearer identities are used for referring to certain information.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the establishment technology of the bearer in the evolution network. Background technique [0002] In order to ensure the competitiveness of a 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") system in the next 10 years or longer, an access technology evolution work is being carried out within the 3GPP organization. Especially in order to strengthen the ability of the 3GPP system to handle the rapidly growing IP data services, the use of packet technology in the 3GPP system needs to be further enhanced. [0003] Such as figure 1 As shown, the core network of the evolved network mainly includes three logical functional modules of a Mobility Management Entity (MME), a Serving Gateway, and a Packet Data Network Gateway (PDN Gateway). [0004] MME is the mobility management module, responsible for the mobility management of the con...
