Problems solved by technology

[0009] For terminals of terminal type 2, on the premise that the 3G network coverage effect is better than the 4G network coverage effect, the interoperability of the 4G network to the 3G network data service connection state using the blind redirection scheme has higher reliability; In this case, the interoperability of data services from 3G network to 4G network will have certain problems if the blind redirection scheme is adopted.

Embodiment 1

[0136] The application scenario of this embodiment is: blind redirection from a 3G network to a 4G network, and the terminal is a terminal of terminal type 2; the trigger conditions for blind redirection include: conditions on the network side and conditions on the terminal side; where the conditions on the network side Including: the 3G cell is configured with 4G neighboring cells; the conditions on the terminal side include: the capability reported by the terminal in the cell includes the ability to support 4G networks, but does not support the ability to measure 4G networks in the connected state.

[0137] The interoperability method between networks provided by this embodiment, such as Figure 5 As shown, once the above trigger conditions are met, the 3G network side periodically executes blind redirection from the 3G network to the 4G network for all terminals in the connected state in the 3G cell by taking the duration T1 of the first timer as a unit. That is to say, the...

Embodiment 2

[0143] The application scenario of this embodiment is: blind redirection from a 3G network to a 4G network, and the terminal is a terminal of terminal type 2; the trigger conditions for blind redirection include: conditions on the network side and conditions on the terminal side; where the conditions on the network side Including: the 3G cell is configured with 4G neighboring cells; the conditions on the terminal side include: the capability reported by the terminal in the cell includes the ability to support 4G networks, but does not support the ability to measure 4G networks in the connected state.

[0144] The interoperability method between networks provided by this embodiment, such as Figure 6 As shown, on the 3G network side that meets the above conditions, the time interval between two blind redirection from the 3G network to the 4G network in the same 3G cell of the terminal meeting the above conditions is longer than the duration T2 of the second timer.

[0145] Spec...

Embodiment 3

[0151] The application scenario of this embodiment is: returning from a 3G network to a 4G network through a cell reselection process, and the terminal is a terminal of terminal type 2.

[0152] The basic idea of ​​the method for interoperability between networks provided in this embodiment is: periodically actively release the terminal in the connected state through the RRC ConnectionRelease message, trigger the terminal to return to the idle state, and keep not sending downlink data to the terminal for a certain period of time, and Reject the terminal's uplink data request, make the terminal in an idle state, so that the terminal returns from the 3G network to the 4G network through the cell reselection process.

[0153] The trigger conditions for cell reselection include: conditions on the network side and conditions on the terminal side; among them, the conditions on the network side include: the 3G cell is configured with a 4G neighbor cell; the conditions on the terminal ...

Abstract

The invention discloses a method for interoperation between networks. The method comprises a first network side initiates a blind redirection process from a first network to a second network to a terminal in a connection state and in a cell corresponding to the first network periodically. Meanwhile, the invention also discloses a network-side device.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for interoperability between networks and network side equipment. Background technique [0002] With the development of data communication and multimedia service requirements, the fourth generation communication technology (4G) network has been built. Generally, the coverage effect of the third generation communication technology (3G) network is better than that of the 4G network. [0003] figure 1 It is a schematic diagram of each network coverage scenario. Such as figure 1 As shown, at the edge of the 4G network coverage, the user interoperates from the 4G network to the 3G network, so as to continue the service on the 3G network; after the user returns to the coverage area of ​​the 4G network, because the 4G network can provide better user experience, Therefore, the user needs to return to the 4G network from the 3G network as soon as possible. [0004...
