Embodiment Construction

[0039] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0040] Such as figure 2 As shown, it is a schematic flowchart of a handover triggering method according to an embodiment of the present invention, which can be mainly described as follows.

[0041] 21. The source base station sends a measurement control (measure control) command to the vehicle terminal.

[0042] Wherein, the measurement control command carries an A3' event, and the A3' ...

Abstract

The invention discloses a switching trigger method, a base station and a terminal. A source base station transmits a measurement control command to a vehicle-mounted terminal, wherein the measurement control command carries an A3' event, and the A3' event expresses that the service cell quality is better than the neighboring cell quality; and before the vehicle-mounted terminal reports a measurement report, if the service cell quality is better than the neighboring cell quality, the source base station receives the A3' event reported by the vehicle-mounted terminal, and sends a switching request command to a target base station according to the A3' event. Through the technical scheme of the invention, the switching time delay index meets the communication requirements of traffic field scenes.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for accessing a network. Background technique [0002] With the development of wireless communication technology, users have higher and higher requirements for wireless services. In order to meet the needs of faster service transmission rate, shorter delay and wider frequency band, the next generation network NGN (Next Generation Network), such as LTE (Long Term Evolution, long-term evolution) technology came into being. [0003] As the evolution of 3G (Third Generation, third-generation mobile communication) technology, LTE improves and enhances the air access technology of 3G. With the deployment of LTE network, the future network operation environment will become more and more complex, reducing the cost of network construction The key factors are improving spectrum utilization, simplifying network structure, providing lower-cost wireless base stations, an...
