Embodiment 1

[0037] According to an embodiment of the present invention, a redirection method assisted by a network control terminal is provided. Figure 4 is a flowchart of a redirection method according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps S402 to S406:

[0038] Step S402, the base station sends a second message to the terminal, wherein the second message carries indication information for enabling the terminal to report the measurement result;

[0039] Step S104, the terminal sends a third message to the base station, where the third message carries measurement result information;

[0040] Step S106, the base station sends a first message to the terminal, where the first message carries information for redirection.

[0041] Then, the terminal can perform the redirection operation.

Embodiment 2

[0043] According to an embodiment of the present invention, a network-assisted terminal control redirection method is provided, Figure 5 is a flowchart of a redirection method according to an embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps S502 to S504:

[0044] Step S502, the base station sends a first message to the terminal, wherein the first message carries redirection system information for enabling the terminal to perform a redirection operation;

[0045]Step S504, the terminal receives the first message sent by the base station, and starts a measurement operation. If the measurement result meets the redirection threshold required by the base station, the terminal accesses the corresponding system (ie, redirection network).

example 1

[0047] In this embodiment, the HRPD system instructs the mobile terminal to redirect to the LTE system as an example for description, but it should be noted that this embodiment is not limited to this, and the content and implementation methods included in this embodiment are also applicable The HRPD system indicates the system redirection requirements of the terminal to other radio access technologies.

[0048] Figure 6 It is a redirection flowchart assisted by a network control terminal based on an HRPD system according to Embodiment 1 of the method of the present invention, such as Figure 6 As shown, the process includes the following steps:

[0049] In step S601, the mobile terminal is located in the HRPD system and is in an idle or connected state.

[0050] Step S602, the mobile terminal moves to the overlapping area covered by the HRPD system and the LTE system.

[0051] In step S603, the HRPD system wishes to redirect the terminal according to information such as t...

Abstract

The invention discloses an inter-heterosystem redirection method and system. The method comprises the following steps: a base station transmits a first message to a terminal to indicate the terminal to perform redirection operation; and the terminal accesses to a redirection network. Through the method and the system, the problem that a mobile terminal completely autonomously performs inter-heterosystem network redirection in an HRPD (High Rate Packet Data) network in a related technology is solved, so that the effects of reducing load of the current network, reducing network operation cost and guaranteeing service quality of the user to the greatest extent are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a redirection method and system between different systems. Background technique [0002] At present, the subsequent evolution network of the Code Division Multiple Access (CDMA) 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 ...
