Abstract
The present invention discloses a method for guaranteeing data not to be interrupted in multi-network connection environment, which applies between a user equipment (UE) connected with multiple networks and the multiple networks, and comprises that, when one or more network connections of the UE have congestion, an IP flow of the UE is transferred to an uncongested network connection from the congested network connection(s). The present invention also discloses a system and a policy server for guaranteeing data not to be interrupted. In the case that multiple network connections are established simultaneously, the present invention guarantees that data is not interrupted and achieves the effects of enlarging bandwidth and optimizing bandwidth by transferring IP flow.
Claims18
A method for guaranteeing data not to be interrupted in multi-network connection environment, applied between a user equipment (UE) connected with multiple networks and the multiple networks, comprising:
- when one or more network connections of the UE have congestion, transferring an IP flow of the UE to an uncongested network connection from the congested network connection(s),
- wherein that the one or more network connections of the UE have congestion is acquired by a policy server,
- when the policy server acquires that the one or more network connections of the UE has congestion, the step of transferring an IP flow of the UE to the uncongested network connection from the congested network connection(s) comprises:
- the policy server initiates to the UE an IP flow transfer request to indicate the UE to transfer an IP flow of a designated service from a network connection of a source network to a network connection of a target network, wherein the source network is a congested network and the target network is a uncongested network;
- and
- the UE transfers the IP flow of the designated service from the network connection(s) of the source network to the network connection of the target network;
- wherein the step of the policy server initiating to the UE an IP flow transfer request comprises:
- the policy server inquires a preset connection policy which is set based on network priority of a UE service, and according to the connection policy, selects as the designated service a service connected with the source network and required to be transferred, selects the target network, and initiates the IP flow transfer request to the UE.
A system for guaranteeing data not to be interrupted in multi-network connection environment, comprising a UE connected with multiple networks, the multiple networks and a policy server, wherein the policy server is configured such that when acquiring one or more network connections of the UE has congestion, the policy server inquiries a preset connection policy which is set based on network priority of a UE service, and initiates to the UE an IP flow transfer request according to the connection policy to indicate the UE to transfer an IP flow of a designated service from a network connection of a source network to a network connection of a target network;
- and the UE is configured to transfer the IP flow of the designated service from the network connection of the source network to the network connection of the target network, wherein the source network is a congested network and the target network is an uncongested network which is selected according to the connection policy.
A policy server for guaranteeing data not to be interrupted in multi-network connection environment, wherein the policy server is configured such that:
- when acquiring one or more network connections of a UE has congestion, the policy server inquiries a preset connection policy which is set based on network priority of a UE service, and initiates to the UE an IP flow transfer request according to the connection policy to indicate the UE to transfer an IP flow of a designated service from a network connection of a source network to a network connection of an target network;
- and the UE can thereby transfer the IP flow of the designated service from the network connection of the source network to the network connection of the target network, wherein the source network is a congested network and the target network is an uncongested network which is selected according to the connection policy.
