Problems solved by technology

[0004] In the current interface specifications, such as CDMA 1x EV-DO, that is, Code Division Multiple Access Enhanced Data Mobile Communication Protocol, the Attribute override (attribute coverage) process is defined, so that the access network and the access terminal (the access terminal only stores one set of Handover parameters) In the connected state, update the handover parameters through the method defined in this process; but limited to the definition of the interface, when the terminal performs soft hand

Embodiment Construction

[0019] The main idea of ​​the present invention is: when the access terminal performs soft handover, the target access network and the source access network exchange information, so that the source access network knows the handover parameters of the target cell in the target access network, and the source access network according to After the setting algorithm determines a set of handover parameters, it notifies the access terminal to update its handover parameters, so that the access terminal uses the handover parameters most suitable for the wireless environment in the handover area to complete the handover.

[0020] In the present invention, the method for updating the switching parameters includes the following steps:

[0021] Step 101, the access terminal sends a route update message to the source access network, and the message indicates the target cell that the access terminal requires to switch into;

[0022] The routing update message may also include the cell to be swit

Abstract

The invention discloses a method for updating switching parameters in the process of soft switching of a terminal among access networks, which comprises the following steps: the access terminal notifies a source access network of a target cell in a target access network required to be switched to; and the source access network acquires the switching parameters of the target cell from the target access network, and updates the switching parameters of the access terminal according to the acquired switching parameters of the target cell. The method of the invention avoids the problems of dropped call, low network performance, switching failure and the like caused by that the switching parameters do not meet the actual wireless conditions when the terminal is in a switching area, increases the success rate of the soft switching of the access terminal, reduces the conditions of dropped call, and enhances the user experience.
