Redirection method, device and system

Abstract

Embodiments of the present invention provide a redirection method, device, and system. The redirection method includes: the user equipment detects that the signal quality of the currently accessed cell is lower than a set threshold; judging whether the user equipment satisfies the set condition; if Judging that the user equipment meets the set conditions, sending a measurement report to the network side, so that the network side sends a redirection command to the user equipment according to the measurement report; if judging that the user equipment does not meet the set conditions If the above setting conditions are not met, the measurement report is not sent to the network side. When the user equipment needs to be redirected, the decision-making operation is made based on the characteristics of the user equipment and the business status, which can not only improve the success rate of redirection, but also effectively prevent the user from being in a state of no network for a long time, and ensure the normal business of the user .

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a redirection method, device and system. Background technique [0002] Long Term Evolution (LTE for short) is a long-term evolution of the Universal Mobile Telecommunications System (UMTS for short) technical standard formulated by The 3rd Generation Partnership Project (3GPP for short). As a new generation of mobile communication technology, LTE can provide higher user rate, lower delay and richer services, while greatly improving user experience. However, the construction of an LTE network is a long process. During this process, there will be areas with poor LTE signal coverage. When the user equipment is in an area with poor LTE coverage, it will send the signal quality measurement report of the cell currently accessed by the user equipment to the network side. In order to avoid service interruption and improve the user's perception of good service e...

Problems solved by technology

[0003] Due to the design limitations of the user equipment and business conflicts, when the user equipment is redirected, it may fail to connect to the 3G network, resulting in the failure of the user equipment to be successfully redirected to the 3G network

For example, most Code Division Multiple Access (CDMA for short) terminals currently support concurrent voice and LTE data (Simultaneous Voice and LTE, SVLTE for short), but do not support concurrent voice and EV-DO data (Simultaneous Voice and EV -DO, referred to as SVDO), so when the user equipment is talking, the CDMA module of the user equipment occupies radio frequency resources, and the 3G module of the user equipment cannot obtain radio frequency resources, resulting in the failure of the user equipment to connect to the 3G network

Therefore, in the prior art, the user equipment receives a redirection command issued by the network side, and the user equipment executes a redirection operation according to the redirection command. For some reason, the user equipment cannot be connected to the 3G network, which will cause the user equipment to be unavailable for a long time. The state of the 3G or LTE network seriously affects the normal business of users
