Inter-system switching method and device

Abstract

The invention relates to the technical field of communication, in particular to an inter-system switching method and device. The method comprises the following steps of calculating a switching successrate and a switching success ratio of inter-system switching requests respectively initiated to adjacent cells by each user in a source cell; based on the switching success rate and the switching success proportion, respectively calculating the switching priority of each neighbor cell, sending the switching priority to each user in the source cell, measuring the former M neighbor cells with higher switching priority in each neighbor cell based on the switching priority when any user in the source cell judges that the A2 event occurs, and reporting a first measurement report to the base station; and receiving a first measurement report reported by any user, and when it is judged that at least one neighbor cell meeting the B2 event condition exists in the first M neighbor cells based on thefirst measurement report, switching the any user from the source cell to the neighbor cell meeting the B2 event condition and having the best level.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for switching between different systems. Background technique [0002] With the rapid development of the 4th Generation mobile communication (4G) network, the IMS-based voice service (Voice over LTE, Volte) gradually enters the life of users. With the advancement of Volte, users who meet the Volte business conditions can become Volte users. [0003] At present, the construction of 4G network is relatively complete, but there are still some pre-planned sites that have not been completed, and the buildings in urban areas are dense and complex. The insufficient depth of 4G network coverage has become an important test for Volte’s business development. According to the current 4G network Due to the coverage situation, the seamless coverage of the Volte service cannot be realized. Under this premise, in order to ensure the voice continuity ...

Problems solved by technology

[0007] The purpose of the embodiments of the present invention is to provide a method and device for inter-system handover to solve the problem in the prior art that the B2 event is triggered due to untimely inter-system handover and / or congestion and interference in neighboring cells. The problem that the handover to the adjacent cell cannot be successful
