Problems solved by technology

[0015] The signaling transmission method adopted according to the existing process will have a certain impact on performance, resulting in a large handover delay
In addition, because in the evolved network, the link between the base stations belongs to the "last mile" link, its bandwidth is limited, and it is the bottleneck of network transmission, and the handover between the base stations will be very frequent, so the signal during handover Make the interaction load heavier, which will put a lot of pressure on the link between the base stations

Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0070] image 3 Shown is the first preferred embodiment of the handover method in the evolved network provided by the present invention. In the handover method provided by the present invention, there can be one or more UEs, and one or more target base stations can also be used. handy icon, image 3 Only one is shown. In the present invention, the evolved base station in the evolved network is called eNodeB, and it can also be called evolved node B or base station in practical applications. Whether it is called eNodeB, evolved node B or base station, its functions are the same.

[0071] like image 3 As shown, the handover method in the evolved network provided by the present invention mainly includes the following steps:

[0072] Step 301: Perform measurement...

Abstract

The present invention discloses radio evolution network realizing switching method and system. It contains through in switching source base station and target base station signaling interaction, adopting plurality of terminal public relevant signaling mode, the signaling interaction between terminal and base station, between base station and access network, adopting each terminal switching corresponding one signaling mode to realize radio evolution network batch switching. Said invention relieves broadband load.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the switching technology in the wireless communication network. Background technique [0002] In order to maintain the competitiveness of the access system of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), research on long-term evolution (LTE, Long Term Evolution) and system architecture evolution (SAE, System Architecture Evolution) in network evolution is ongoing . The goal of network evolution is to simplify the network structure and reduce the access time delay. In the future wireless evolution network system, there are many candidate schemes for the network evolution architecture, among which the two-layer node architecture is more popular, such as figure 1 shown. The access gateway (AGW, AccessGateway) is the access gateway of the evolved global terrestrial radio access network (E-UTRAN, Enhanced Universal Terrestrial Radio Access N...
