Embodiment 1

[0021] Embodiment 1 of the present invention provides a service switching device, and its implementation method is as follows figure 1 shown, including:

[0022] A data transmission module 1001, configured to transmit PS service data in the first network through the first packet data protocol PDP link;

[0023] A link request module 1002, configured to request to establish a second PDP link located in the second network when a network signal of the second network is detected;

[0024] A service switching module 1003, configured to switch to the second PDP link after the second PDP link is established and activated.

[0025] The device provided by the embodiment of the present invention provides a method for implementing service switching by a multi-mode terminal, thereby ensuring that the terminal can switch flexibly between communication networks of different modes, and improving call quality.

Embodiment 2

[0027] On the basis of Embodiment 1, in order to ensure call quality, the effectiveness of handover is improved. Preferably, the link request module 1002 is specifically configured to, when a network signal of the second network is detected, compare the network signal quality of the second network with the network signal quality of the first network, if the network signal quality of the second network The quality is better than the network signal quality of the first network, requesting to establish a second PDP link located in the second network.

[0028] Through signal quality comparison, only when the network signal quality of the second network is better than the network signal of the first network, it requests to switch to the second network, which effectively guarantees the communication quality.

Embodiment 3

[0030] On the basis of the second embodiment, preferably, the data transmission module 1001 is further configured to send the uplink data to the second PDP link after being processed by the VPN through the first PDP link, and send the uplink data to the second PDP link through the second PDP link. The PDP link sends the uplink data to the network side.

Abstract

The invention aims to provide a service switching device which comprises a data transmission module, a link request module and a service switching module. The data transmission module is used for transmitting packet-switched PS service data in a first network through a first packet data protocol PDP link. The link request module is used for detecting network signals of a second network and requesting to establish a second PDP link locating in second network. The service switching module is used for switching the first PDP link to the second PDP link after the second PDP link is established and activated. The service switching device provides a manner for realizing service switching of a multimode terminal, the terminal can be switched flexibly among communication networks in different modes, and connection quality is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a service switching device. Background technique [0002] At present, multiple types of communication networks coexist. Therefore, mobile terminals are usually multi-mode terminals that can support access to multiple communication networks. At present, the way to realize the service handover of the multi-mode terminal has not been solved well. Contents of the invention [0003] The object of the present invention is to provide a service switching device, so as to solve the above technical problems. [0004] The purpose of the present invention is achieved in the following ways: [0005] A service switching device, comprising: [0006] A data transmission module, configured to transmit PS service data in the first network through the first packet data protocol PDP link; [0007] A link request module, configured to request to establish a second PDP link located in the...
