Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The present invention provides a path switching method based on intra-site switching, referring to figure 1 , in an embodiment, the path switching method based on intra-site switching includes:

[0047] Step S1, detecting whether the terminal has completed the handover between cells in the base station;

[0048] In this embodiment, the communication process of the mobile communication system usually involves the terminal, the access network and the core network, wherein the terminal is a user equipment, usually a mobile phone. Of course, with the development of mobile communication technology, the terminal may appear in other forms , as long as it can support the relevant communication protocols of the mobile communication system. The terminal accesses the core network through the base station to realize comm...

Abstract

The invention discloses a path switching method based on intra-station switching. The method comprises the following steps of detecting whether a terminal completes switching between cells in a base station; when a message that the terminal completes the intra-station switching is received, extracting GTP-U layer tunnel information; comparing the extracted GTP-U layer tunnel information with the GTP-U layer tunnel information before terminal switching; and if path information before and after the terminal switching is not consistent, carrying out path information exchange with a core network in order to complete path switching. The invention further discloses a switching system. According to the method and the system, a problem that the terminal has call drop after the terminal switches between the cells in the base station can be solved, so that the service continuity is guaranteed, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a path switching method and switching system based on intra-site switching. Background technique [0002] User mobility scenarios are usually divided into three types: cross-core network handover, cross-base station inter-cell handover, and cross-same base station inter-cell handover. Taking the new generation of mobile communication standard LTE (Long Term Evolution, long-term evolution technology) as an example, for the first two types of handover, the LTE standard provides two handover processes of S1 handover and X2 handover The LTE standard does not provide an implementation process for handover between cells of the same base station. For example, before and after inter-cell handover in the base station, if the path changes, how to deal with the 3GPP protocol, but there is no description of the implementation process. Therefore, the current base station usually...
