Problems solved by technology

[0036] It can be seen that in the above two existing technologies, the information used by PDF for policy decision-making mainly comes from the P-CSCF, which is very limited, and the corresponding decision-making policies are also very limited, and the supported policies are only based on session requests. The policy of QOS resource information cannot support policies based on user subscription level, service level, user access type, user current access location, user home domain, etc.

no. 1 example

[0142] The first embodiment: user subscription class,

[0143] In this embodiment, user subscription policy information is used. In other words, when resources are limited, the network can give priority to QOS authorization for users with high user levels or high-priority services. Resource authorization for low-priority services, which supports preempting resources of low-priority users or services for special-level users or services.

[0144] In this embodiment, the network element functions and interfaces in the original network are extended such as Figure 7 shown.

[0145] Figure 7 The extended interfaces in include:

[0146] (1) Based on the Mw interface of the SIP protocol, the expansion supports the transfer of information related to QOS policy control between servers;

[0147] (2) Based on the Cx interface of the diameter interface, the expansion supports the transmission of information related to QOS policy control;

[0148] (3) The Gq interface based on the dia...

no. 2 example

[0170] The second embodiment: the service class policy information corresponding to the current request

[0171] In this embodiment, the service class policy information corresponding to the current request is used. The same as the above-mentioned user subscription policy information, it means that when resources are limited, the network can give priority to guaranteeing QOS authorization for users with high user levels or high-priority services. Deny resource authorization for low-priority users or low-priority services. Supports preempting resources of low-priority users or services for special-level users or services.

[0172] In this embodiment, the network element functions and interfaces in the original network are extended such as Figure 8 shown.

[0173] Figure 8 The extended interfaces in include:

[0174] (1) Based on the ISC interface of the SIP protocol, the expansion supports the transfer of information related to QOS policy control between servers;

no. 3 example

[0193] The third embodiment: current access type and location policy information

[0194] In this embodiment, current access type and location policy information are used. Specifically, it means that when the user's access type is known, the network can control the resources used by the user according to the capabilities that the access type can achieve, or control the allocation strategy of QOS resources according to the access type. When the current location of the user is known, the network can control the policy of the user's QOS resource usage according to the current location of the user.

[0195] In this embodiment, the network element functions and interfaces in the original network are extended such as Figure 9 shown.

[0196] Figure 9 Extended special network elements in:

[0197] (1) Network Element of Access Info (access information network element, also referred to as the third network element in the present invention), providing access information, includin...

Abstract

The invention relates to a method for confirming the quality of data transmission service in the communication network, to improve the utilization efficiency of transmission resource. Wherein, when deciding the QoS, using the request message of UE to the QoS, as well as using the network information or operation information as user contrast strategy information, service strategy information, access type, position strategy information and access network local service strategy. Based on IMS or similar network, said network information or operation information can be obtained by P-CSCF to be sent to the PDF to be decided, or obtained by P-CSCF to be projected into uniform propriety according to the local set, to be sent to the PDF, or obtained and stored by S-CSCF, and modify the SDP description when user initializes the service request or reject the service request.

Description

technical field [0001] The present invention relates to a quality of service realization technology, in particular to a method for realizing quality of service in an Internet Protocol Multimedia Subsystem (IPMultimedia Subsystem, "IMS" for short) and similar networks. Background technique [0002] IMS is an IP multimedia subsystem in the WCDMA network defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") R5 / R6 standard. Target network for business and applications. The IMS uses the IP packet domain as the bearer channel for its control signaling and media transmission, and uses the Session Initiation Protocol (SIP) protocol as the call control signaling to realize the integration of service management, session control and bearer access. The three are separated. [0003] The main functional entities in IMS include: [0004] Call Session Control Function (Call Session Control Function, referred to as "CSCF"), used to c...
