Problems solved by technology

[0021] The disadvantage of the above migration process is: the whole migration process is more complicated
In order to ensure the delay of the handover process, during the migration process, the data in the source ERS, such as the UE context information it saves, cannot be transferred from the source ERS to the target ERS as in the lossless migration process, resulting in a large amount of data lost

Embodiment Construction

[0068] The present invention provides a wireless access network architecture and a method for implementing lossless migration of real-time services. The core of the present invention is to replace UE context transfer by moving up and down the air interface protocol stack, which simplifies the migration process.

[0069] The wireless access network architecture proposed by the present invention is a new two-layer node network architecture. This architecture redesigns the functions of ERS and IAGW of the existing two-layer node network architecture. details as follows:

[0070] The air interface protocol stack in ERS has evolved from the original MAC / RLC / PDCP to E-MAC (extended MAC) / E-RLC (extended RLC). In addition to retaining the original MAC layer functions, E-MAC also Added the original division / cascade function of the RLC layer. For data services carried in AM (Answer Mode) mode. E-RLC inherits the ARQ (Automatic Repeat Request) function of the original RLC layer that p...

Abstract

The invention relates to a wireless access network and relative real-time service non-damage transfer method. The method comprises that: when UE has region switch, a source edge wireless base station (ERS) uplinking the setting information of wireless interface protocol stack to an IP access network gate (IAGW); the IAGW via said setting information building relative wireless interface protocol stack to receive and store the real-time service data of UE; when the UE region switch is completed, the IAGW sending the setting information of said wireless interface protocol stack to a target ERS of UE; the target ERS via setting information building relative wireless interface protocol stack to receive the real-time service data from the IAGW. The invention can confirm the real-time property of UE switch and realize non-damage transfer between source base station and target base station.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a wireless access network architecture and a method for realizing lossless migration of real-time services. Background technique [0002] UMTS (Universal Mobile Telecommunications System, universal mobile communication system) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) air interface technology, and UMTS system is usually called WCDMA communication system. The UMTS system adopts a system structure similar to that of the second generation mobile communication system, and its system structure is as follows: figure 1 shown. The system structure mainly includes RAN (Radio Access Network, wireless access network) and CN (Core Network, core network). Among them, RAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in the ...
