Embodiment 1

[0042] The present invention provides a blind handover and blind redirection method based on assisted GPS (Assisted GPS, A-GPS), see figure 2 , the method includes:

[0043] S201. When the terminal determines that blind handover or blind redirection is required according to preset trigger conditions, use the assisted GPS function to obtain the location information of the terminal;

[0044] The preset trigger condition includes: the received signal strength of the currently serving base station deteriorates and affects the link quality. Of course, those skilled in the art can also set other trigger conditions according to actual needs.

[0045] The step of using the assisted GPS function to obtain the location information of the terminal specifically includes:

[0046] The base station and GPS satellites are used to jointly acquire the location information of the terminal.

[0047] The present invention jointly obtains the location information of the terminal through the te...

Embodiment 2

[0075] An embodiment of the present invention provides a terminal, see Figure 6 ,include:

[0076] The first acquisition unit is configured to use the assisted GPS function to acquire the location information of the terminal when it is determined that blind handover or blind redirection is required according to preset trigger conditions;

[0077] a sending unit, configured to send the location information to the current serving base station;

[0078] A handover redirection unit, configured to perform blind handover or blind redirection under the control of the serving base station.

Embodiment approach 1

[0080] The first obtaining unit is specifically configured to use the assisted GPS function to obtain the location information of the terminal when it is determined that blind handover or blind redirection is required according to the received signal strength of the current serving base station being lower than a preset threshold.

Abstract

Disclosed are a blind handover or blind redirection method, system and related device. The method comprises: when a terminal judges that blind handover or blind redirection is required according to a preset trigger condition, a current serving base station of the terminal acquiring location information acquired by the terminal by using an auxiliary GPS function; and according to the location information and pre-stored location information about various adjacent base stations, the serving base station calculating the distance between the terminal and various adjacent base stations, determining a target base station for blind handover or blind redirection and performing blind handover or blind redirection. By means of the present invention, the problems that the failure of blind handover or blind redirection has an influence on the user experience, and re-access consumes network resources in the prior art are effectively avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a blind handover or blind redirection method, system and related equipment. Background technique [0002] In modern wireless communication networks, a cellular network topology is used. There are many other adjacent base stations around the base station covered by a base station, and usually only one or a few of them are suitable as the target base station for terminal blind handover or blind redirection. Blind handover or blind redirection means that the base station does not require the terminal to measure Neighboring cells and report, but directly order the terminal to handover or redirect to a target base station. After all, there is no measurement result as a selection support, and the blind handover or blind redirection of the base station may select an inappropriate target base station, resulting in failure and affecting user experience. If there are re...
