Problems solved by technology

[0004] 2. The evolved network architecture must minimize the delay of user data;
[0032] from Figure 4 It can be seen from the figure that in the current handover process, after the terminal is successfully handed over from the source network to the target network, the bearer of the source network has been idle, and no consideration has been given to releasing the bearer resources of the source network in time. Therefore, the current handover process, in After the terminal is switched to the target network, resources are wasted and resource utilization efficiency is reduced

Embodiment 1

[0143] Figure 10 It is a schematic flow chart of bearer establishment and release in the process of handover from 3GPP to non-3GPP network controlled by PCRF synchronously according to the embodiment of the present invention. see Figure 10 , the 3GPP network can be accessed based on GTP or MIP, and the process includes:

[0144] Step 1001, the terminal establishes a connection with the 3GPP network;

[0145] In this step, after the terminal establishes a connection with the 3GPP network, an uplink and downlink packet data unit (PDU, Packet Data Unit) is transmitted between the terminal and the Network Anchor through the 3GPP network.

[0146] Step 1002, the terminal discovers a non-3GPP network and accesses the non-3GPP network;

[0147] Step 1003, the terminal establishes a connection with the non-3GPP network access gateway (Non-3GPP AGW) and establishes a MIP tunnel to the Network Anchor;

[0148] In this step, after the terminal establishes a connection with the Non-...

Embodiment 2

[0168] In Embodiment 1, the bearer establishment process of the target network and the bearer release process of the source network are synchronous processes. In practical applications, the bearer establishment process of the target network and the bearer release process of the source network may also be asynchronous processes.

[0169] Figure 11 It is a schematic flow chart of bearer establishment and release during the process of handover from 3GPP to non-3GPP network triggered by PCRF asynchronous control triggered by the non-3GPP AGW according to Embodiment 2 of the present invention. see Figure 11 , the 3GPP network can be accessed based on GTP or MIP, and the process includes:

[0170] Step 1101~step 1104, same as step 1001~step 1004;

[0171] Step 1105, the PCRF generates a corresponding PCC Rule according to the received IP-CAN Session establishment instruction message, carries it in the IP-CAN Session establishment response message, and sends it to the Non-3GPP AG...

Embodiment 3

[0187] Figure 12 It is a schematic flow chart of bearer establishment and release in the handover process from 3GPP to non-3GPP network triggered by PCRF asynchronous control triggered by a non-3GPP Network Anchor in Embodiment 3 of the present invention. see Figure 12 , the 3GPP network can be accessed based on GTP or MIP, and the process includes:

[0188] Step 1201~step 1203, same as step 1101~step 1103;

[0189] Step 1204, the non-3GPP Network Anchor sends an IP-CAN Session establishment indication message to the PCRF, requesting to generate a corresponding PCC Rule;

[0190] In this step, the IP-CAN Session establishment instruction message includes parameter information such as User-ID, Home Address, Non-3GPP AGW IP Address, APN, and RAT Type. Among them, the RAT Type is used to identify the type of the current access network, and the AGW IP Address is an optional parameter. If the establishment of the IP-CAN Session between Non-3GPPAGW and PCRF is initiated by the ...

Abstract

The invention discloses a method for releasing source network resource in the revolved network switching process, which includes the following steps: in or after the target network loading establishment, PCRF controls the release of the source network resource system synchronously or asynchronously; in the release process of the synchronous control source network resource of PCRF, the target network sends messages to PCRF, which needs to generate new PCC regulations for the target network, after the establishment of the target network loading, the target network sends messages to inform PCRF, and trigger PCRF to start the process of source network loading release; the target network loading establishment and the source network resource release process are carried asynchronously, that is, after the PCRF receives the IP access network communication establishment message send by the target network, the PCC determination providing message is send to the source network access gateway, the loading of the source network and related resource is needed to be released. Using the invention can carry out the release of source network loading resource in time, thereby improving the use efficiency of source network loading resource, and reducing the waste of resource.

Description

technical field [0001] The present invention relates to network handover technology, in particular to a method and system for releasing source network resources during an evolutionary network handover process. Background technique [0002] In order to ensure the competitiveness of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) system in the next 10 years or even longer, within the 3GPP organization, related evolutionary access technologies are being developed, especially to strengthen The ability of the 3GPP system to handle the rapidly growing IP data services needs to further enhance the use of packet technology in the 3GPP system. The network containing these evolved packet technologies is called Evolved Packet System (EPS, Evolved Packet System). The most important parts of its evolved technologies include: reduced delay, higher user data rate, enhanced system capacity and coverage The scope and the reduction of the overall cost of ope...
