Embodiment 1

[0020] Such as figure 1 As shown, it is a schematic diagram of a PMIP-based QoS control method in Embodiment 1 of the present invention, and the method includes the following steps:

[0021] Step 101: For each pending service to be executed by the terminal, create a tunnel for transmitting data packets of the pending service.

[0022] In this embodiment, one tunnel is used to transmit data packets of one service.

[0023] The created tunnel can be a tunnel encapsulated by GRE between the MAG and LMA, or can be a tunnel encapsulated by other methods such as IP IN IP or UDP.

[0024] In this step, the purpose of creating tunnels for each to-be-executed service of the terminal can be achieved by extending the PMIP protocol. The specific method is: add the channel type option in the PMIP protocol content, the terminal defines a tunnel for each service in the channel type option, and notifies the MAG of the PMIP protocol request carrying the channel type option, and the MAG accor...

Embodiment 2

[0040] Embodiment 2 of the present invention also provides a PMIP-based QoS control system, such as figure 2 As shown, the system includes a tunnel creation unit 11, an information setting unit 12, and a control unit 13, wherein: the tunnel creation unit 11 is used to create a tunnel for transmitting data packets of the pending service for each pending service of the terminal; The information setting unit 12 is used to set the QoS type information for each tunnel according to the service to be executed corresponding to the tunnel; the control unit 13 is used to perform QoS control on the data packets transmitted through the tunnel according to the QoS type information set for the tunnel.

[0041] The tunnel created by the tunnel creation unit 11 is a tunnel encapsulated in a GRE manner.

[0042] The QoS type information set by the information setting unit 12 includes but is not limited to at least one of the following information:

[0043] The maximum bandwidth allowed, the ...

Abstract

The invention discloses a proxy mobile internet protocol (PMIP)-based quality of service (QoS) control method and a PMIP-based QoS control system. The QoS control method mainly comprises the following steps of: carrying out expansion on a PMIP; establishing tunnels for each service of a terminal; and setting QoS type information for each tunnel so as to realize the QoS control of data packets of each service in the tunnels in the transmission process. Compared with the prior art, the method and the system have the characteristics of realizing the QoS control with lower granularity and the differentiation control aiming at services.

Description

technical field [0001] The invention relates to the communication field, in particular to a proxy mobile IP (PMIP)-based QoS control method and system. Background technique [0002] Multiple tunnel encapsulation methods such as IP IN IP and UDP are defined in the current PMIP specification, and the GRE tunnel encapsulation method is also defined in the draft of extended PMIP. Data packets are transmitted after tunnel encapsulation through the above tunnel encapsulation methods. In the process of transmitting data packets through encapsulation tunnels, the transmission network does not treat the encapsulated tunnels differently, that is to say, the quality of service (QoS) of the process of transmitting data packets in each tunnel is the same. [0003] In order to facilitate QoS management for users, the draft of the IETF NETEXT working group proposes extended PMIP signaling, by adding QoS options in PMIP signaling. When creating a GRE tunnel for a terminal between the MAG a...
