Problems solved by technology

For such as Figure 1a Mode 1 shown), because the number of quintuples in this type of application is large and changeable, it is necessary to refresh the TFT carried by the EPS multiple times (even incalculable times), which will cause serious signaling storms; Figure 1b The mode 2 shown above requires the EPS network to support multiple (even immeasurable) EPS bearers, which is unrealistic

Embodiment 1

[0129] figure 2 It is a flow chart of application-based bearer binding according to preferred embodiment 1 of the present invention, as shown in figure 2 As shown, the process is based on mode 1) in the background technology, that is, both the application detection DPI function and the bearer binding function are integrated in the P-GW. The process mainly includes the following steps:

[0130] Step S201: the terminal UE initiates a certain application or several applications with the communication peer. The type of application studied here is non-derivable, the quintuple is changeable, or when the operator configures certain applications to be detected, such as terminal browsing web pages. The P-GW serving as an application detection function has detected the one or more applications. The P-GW performs application detection according to the ADC rules installed or activated before the PCRF.

[0131] Step S202: The P-GW reports the type of the detected application (App ID,...

Embodiment 2

[0143] image 3 It is a flow chart of application-based bearer binding according to preferred embodiment 2 of the present invention, such as image 3 As shown, the flow chart is based on mode 3) in the background technology, that is, the application detection DPI function is independently deployed on the TDF, and the P-GW serves as the bearer binding function. The process mainly includes the following steps:

[0144] Step S301: the terminal UE initiates a certain application or several applications with the communication peer. The type of application studied here is non-derivable, the quintuple is changeable, or when the operator configures certain applications to be detected, such as terminal browsing web pages. The TDF as an application detection function detects the one or more applications.

[0145] Step S302: The TDF reports the type of the detected application (App ID, application type identifier) ​​to the PCRF through the Sd session.

[0146] Step S303: According to...

Embodiment 3

[0161] Figure 4 It is a flow chart of application-based bearer binding according to preferred embodiment 3 of the present invention, as shown in Figure 4 As shown, the flowchart is based on mode 4) in the background technology, that is, the application detection DPI function is independently deployed on the TDF, and the S-GW serves as the bearer binding function. The process mainly includes the following steps:

[0162] Step S401-Step S402: It is exactly the same as Step S301-Step S302, and will not be repeated here.

[0163] Step S403: basically the same as step S303. The difference is that the PCRF also needs to formulate the QoS information sent to the S-GW.

[0164] Step S404: Because the S-GW performs the bearer binding function, the PCRF sends the data packet label and QoS information to the S-GW through the Gxc interface; optionally, the PCRF sends the data label to the P-GW through the Gx session.

[0165] The data packet label sent to P-GW is no longer used for ...

Abstract

Disclosed are a bearer binding method and system. The method comprises: a PCRF receiving type information, sent by an application detection function, of a detected application, determining a QoS policy applied on the application, and notifying a bearer binding function of the QoS policy; and the bearer binding function executing application-based bearer binding according to the QoS policy. Through the present invention, bearer binding can be performed on a non-deducible application, and the QoS of the non-deducible application can be ensured.

Description

technical field [0001] The present invention relates to a bearer binding technology, in particular to a bearer binding method and system in an evolved packet system (EPS, Evolved Packet System). Background technique [0002] The Evolved Packet System (EPS, Evolved Packet System) of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is composed of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW or PDN GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server) , Policy and Charging Rules Function (PCRF, Policy and Charging Rules Function) entities and other supporting nodes. [0003] Figures 1a-1d It is a schematic diagram of the architecture of the EPS system of the 3GPP network, as shown in Figure 1. In the EPS ...
