example 1

[0063] figure 2 It is a flow chart of redirection using unicast mode based on HRPD system according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0064] Step S201, the mobile terminal is located in the HRPD system and is in an idle state;

[0065] Step S202, the mobile terminal moves to the overlapping area covered by the HRPD system and the LTE system;

[0066] Step S203, the mobile terminal sends a connection request message and a routing update message, requesting access to the HRPD system;

[0067] In step S204, the HRPD system decides to redirect the terminal according to the current system load. According to the pilot measurement results contained in the routing update message reported by the terminal, the base station accurately selects several suitable neighbor cells of the LTE system to fill in the record of the neighbor cell of the different system used for the redirection message, and sets the ...

example 2

[0070] image 3 It is a flow chart of redirection using a broadcast mode based on an HRPD system according to a method embodiment of the present invention, such as image 3 As shown, the process includes the following steps:

[0071] Step S301, the mobile terminal is located in the HRPD system and is in an idle state;

[0072] Step S302, the mobile terminal moves to the overlapping area covered by the HRPD system and the LTE system;

[0073] In step S303, the HRPD system decides to redirect some terminals under the system according to the current system load. In addition to setting the RedirectToOtherRAT field to "1", the base station broadcasts and sends a message for redirection, and also needs to include the access level information of the mobile terminal that allows redirection.

[0074] Step S304, after receiving the above message, the mobile terminal first matches its own access level with the access level that allows redirection contained in the message, and the mobi...

Embodiment 1

[0076] According to an embodiment of the present invention, a base station is provided, Figure 4 is a structural block diagram of a base station according to an embodiment of the present invention, such as Figure 4 As shown, the device includes: a sending module 42, configured to send a message to the terminal, where the message carries redirection system information for enabling the terminal to perform a redirection operation.

[0077] The sending module 42 includes: a sending submodule 422 and a rejecting submodule 424, the structure of which will be described in detail below.

[0078] The sending sub-module 422 is used to send a message to the terminal in unicast mode when the terminal requests to access the base station; the rejecting sub-module 424 is connected to the sending sub-module 422 and used to reject the terminal's access request.

[0079] Preferably, the sending module may further include: a second sending submodule 426, which is configured to send a message ...

Abstract

The invention discloses a redirection method, a base station and a terminal. The method comprises that: the base station sends a message to the terminal, wherein the message carries redirection system information used for the terminal to perform redirection operation. The method solves the problem that the delay is long to influence the user experience when a mobile terminal in an HRPD network autonomously performs alien system network reselection in the related technology so as to reduce the network load and ensure the quality of service for current online users maximally.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a redirection method, a base station and a terminal. Background technique [0002] At present, the subsequent evolution network of the Code Division Multiple Access (CDMA) access technology and the network of other wireless access technologies, especially the interoperability of the Long Term Evolution (LTE) network It is a trend in the development of wireless communication. However, it will be a complex replacement process to evolve from a commercially available CDMA network to an LTE network, and in this replacement process, there will be a long period of coexistence, during which the two wireless networks will be interconnected. [0003] Taking CDMA High Speed ​​Packet Data (HRPD for short) system as an example, for a mobile terminal in the HRPD network, especially a mobile terminal in a critical area, the HRPD network should provide some mechanism to instruct the terminal...
