Method and equipment for switching pilot beacons of data only revision B (DORB) service

Abstract

The invention provides a method and equipment for switching pilot beacons of a data only revision B (DORB) service. The method comprises the following steps of: receiving a route update (RU) message reported by a terminal; and performing switching judgment of the pilot beacons if frequency points corresponding to pilot strength information carried in the RU message include the usable pilot beacons. The switching judgment of the pilot beacons comprises the processes of: performing the switching judgment on each sub-active set in a current active set of the terminal according to the pilot strength information to obtain a judgment active set; triggering soft switching if the judgment active set and the current active set have the sub-active sets corresponding to the same frequency points; and triggering hard switching if the judgment active set and the current active set do not have the sub-active sets corresponding to the same frequency points . In the embodiment of the invention, a concept of the pilot beacon of the service is provided, the pilot beacons are allowed to participate in the soft switching, a convention of triggering the hard switching by the pilot beacons is changed, and the switching judgment is performed on the sub-active sets according to the characteristics of the active set of the DORB, so that the unnecessary hard switching can be avoided, the quality of service is improved, and call drop is avoided.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a pseudo-pilot switching method and equipment for evolution enhanced version B (EV-DoRev.B, DORB) service. Background technique [0002] Pseudo-pilot hard handover has been well applied in Code Division Multiple Access (CDMA) 1x and Evolution Enhanced Version A (EV-DoRev.A, DORA). The pseudo-pilot hard handover process is roughly as follows: the access terminal (Access Terminal, AT) first accesses in cell 1, corresponding to a current active set, when the AT moves to the direction of cell 2, the pilot strength of cell 2 is getting higher and higher. strong, trigger AT to send a route update (Route Update, RU) message, the RU message contains the pilot strength of each pilot detected, and the access network (Access Network, AN) judges that the pilot strength in the RU message is greater than the pre-set After the false pilot with the set threshold, the judgment triggers ...

AI Technical Summary

Problems solved by technology

If the AT stays between cell 1 and cell 2 after moving to cell 2 for a while, or if the AT moves in the direction of cell 1, unnecessary handover is triggered; or, when many users are between cell 1 and cell 2 Moving back and forth will trigger multiple handovers, resulting in a large number of signaling interactions, a sharp drop in service quality, and easy call drop

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: 1x and DORA are single-carrier systems, while DORB is a multi-carrier system, so the pseudo-pilot hard handover scheme in 1x and DORA cannot be directly borrowed

In addition, the above-mentioned handover scheme will lead to unnecessary handover or even ping-pong handover, which in turn will cause service quality degradation or even call drop

Furthermore, the existing pseudo-pilots do not undertake services, and there is a waste of resources
