Method for controlling network resources during service flow transfer

A network resource and resource control information technology, applied in the field of network resource control, can solve the problems of not being able to know the relevant information of the release source network users, prolonging the flow migration process, and not being able to know the users, so as to improve network operation efficiency, Enhance controllable performance and save the effect of business flow migration process

Problems solved by technology

However, when the business flow is migrated between different systems, the existing network cannot make a judgment on the business flow migration factors, so it cannot know whether to release the relevant information of the source network user, resulting in the network resources being unable to be well controlled and manage
[0008] When a user wants to migrate some service flows, since the network cannot know which service flows the user wants to migrate, one solution for the existing network is to first establish a default bearer, and then establish a dedicated bearer. When the service flow Migration is a factor of wireless signal coverage (for example, there are multiple wireless signal coverages of 3GPP and non-3GPP indoors, while there are only 3GPP network signals outdoors), which may make the bearer establishment time longer
Of course, the existing network can also establish the default bearer and dedicated bearer together, and let the user initiate the deletion of services that do not want to be migrated. Obviously, this method will not only prolong the flow migration process, increase the network processing Users charge more business usage fees, thereby reducing user experience

Embodiment 1

[0040] image 3 It is the process of Embodiment 1 of the present invention. The UE first accesses the P-GW through a trusted non-3GPP access network. When the UE decides to migrate some service flows from the non-3GPP access network to the 3GPP access network, the default bearer is established in the 3GPP access network. process. When accessing through 3GPP, the core network may adopt PMIPv6 protocol, GTP (General Tunneling Protocol, general tunneling protocol) or DSMIP protocol. In order to simplify the description, this embodiment only takes the scenario where the 3GPP core network adopts the PMIP protocol as an example. Other implementation scenarios, such as the use of GTP and the DSMIP protocol, are very similar to this embodiment and will not affect the description of the present invention. Therefore, I won't repeat it here.

[0041] In an embodiment, the P-GW acquires the resource release indication as follows: when the 3GPP default bearer is established, the attach ...

Embodiment 2

[0056] Figure 4 It is the flow process of Embodiment 2 of the present invention. First, the UE has already connected to the same P-GW through a trusted non-3GPP and 3GPP access network. When the UE decides to migrate some service flows from the non-3GPP access network to the 3GPP access network, it initiates The process of establishing a dedicated bearer. The GTP protocol is adopted between the S-GW and the P-GW when accessing through 3GPP.

[0057] In Embodiment 2 and Embodiment 3, the P-GW obtains the resource release indication in this way: when the 3GPP bearer resource is modified, the bearer resource modification request sent by the user terminal UE to the mobility management unit MME carries the resource release indication, the resource release indication is uploaded to the P-GW. After receiving the dedicated bearer establishment request sent by the MME, the S-GW sends a proxy binding update message to the P-GW, and the P-GW responds with a binding confirmation mess...

Embodiment 3

[0068] Figure 5It is the process flow of Embodiment 3 of the present invention. First, the UE has already connected to the same P-GW through a trusted non-3GPP and 3GPP access network. When the UE decides to migrate some service flows from the non-3GPP access network to the 3GPP access network, it initiates The process of establishing a dedicated bearer. The PMIP protocol is used between the S-GW and the P-GW when accessing through 3GPP. The specific steps are described as follows:

[0069] Step 501, the UE accesses the same P-GW through the 3GPP and non-3GPP access networks, and related services are transmitted through the non-3GPP system;

[0070] Step 502, the UE decides to migrate certain service flows from the non-3GPP system to the 3GPP access system according to the local policy;

[0071] Step 503, the UE sends a bearer resource modification request to the MME to establish a dedicated bearer, which carries a resource release indication;

[0072] Step 504, the MME ...

Abstract

A method and a system for controlling network resources during a service flow migrating procedure are provided. The method includes the following steps. During the service flow migrating procedure, user equipment sends the resource control information to the gateway of the target network, and the gateway of the source network or the target network controls the network resources of its network according to the resource control information or Quality of Service (QoS) policy corresponding to the resource control information. The method and the system improve the network operation efficiency, and optimize the processing procedure.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for controlling network resources during service flow migration.
