Problems solved by technology

But there are also some problems, such as requiring all routers in the path to support negotiation protocols, such as the RSVP protocol
[0028] In addition, for an IP access network without PDF and PEP functions, how to negotiate the end-to-end service quality with the resource controller of the external network for the gateway accessing the external network, such as the GGSN in the GPRS packet domain, is currently There is no solution proposed in the technology

[0087] In this embodiment, the inter-domain negotiation is initiated by the PEP and there is only one external network using the hybrid path mode. The network architecture of the system is as Figure 4 As shown, the networks at both ends of the session are located in two domains connected through the external backbone IP network. The domain that initiates the negotiation has PEP and PDF, and the external backbone IP network has a resource controller.

[0088] In order to realize the QoS inter-domain negotiation of the hybrid path mode between the PEP and the external network resource controller, the PEP in this embodiment is configured with the following functional units:

[0089] In the information configuration unit, the routing information of the external network has already been configured in the local routing of the PEP. In this embodiment, addressing information such as the resource controller address or network segment of the external network needs to be configured.

[0113] In this embodiment, the PEP initiates the inter-domain negotiation, and the PEP is directly connected to multiple external networks using different negotiation modes, such as ON-PATH mode and hybrid path mode. The network architecture of the system in this embodiment is as follows Figure 5 As shown, the difference from the first embodiment is that the PEP in the domain initiating the negotiation is directly connected to multiple external networks, and some of these external networks use ON-PATH mode negotiation, and some use hybrid path mode negotiation, Some can negotiate in two modes of ON-PATH and hybrid path. Some can support multiple modes of negotiation, and this embodiment takes the selection of ON-PATH and hybrid path modes as an example.

[0114] In order to realize inter-domain negotiation with multiple directly connected external networks, the PEP of this embodiment needs to add three related functional units:

[0135] In this embodiment, the GGSN initiates the inter-domain negotiation, and the GGSN is directly connected to multiple external networks using different negotiation modes. The network architecture of the system is as Figure 7 As shown, the PDF is not configured in the GPRS packet domain, and the PEP function is not configured on the GGSN, so the methods of the first and second embodiments cannot be used, and the GGSN needs to be based on the user's subscription information and activation parameters (such as the target IP address, QoS parameters, etc.) initiate a negotiation request to the external network.

[0136] In order to realize the QoS inter-domain negotiation with multiple external networks, an information configuration unit, a Gw interface, a negotiation request initiation unit and a negotiation processing unit in the hybrid path mode need to be set on the GGSN in this embodiment, and a negotiation request initiation unit and a negotiation processing unit in the ...

Abstract

The domain negotiation method for P2P QoS comprises: configuring the net element accessed network and connected to outside network directly for data transmission to let it have function for QoS negotiation as the RNIP; then, when one piece of business in domain need external resource guarantee and the external network manages the local resource by a controller, the RNIP obtains necessary information for negotiation and selects addressing information of external resource controller to pack into a resource request information to send to the controller and receive response information. This invention combines advantages of OFF-PATH and ON-PATH mode.

Description

technical field [0001] The present invention relates to the service quality guarantee of the third generation mobile communication system, more specifically, relates to the core network side end-to-end service quality guarantee and inter-domain negotiation method and system. Background technique [0002] The technology involved in the present invention is based on the following two technical foundations: intra-domain and inter-domain end-to-end QoS guarantee systems. QoS (Quality of Service) is an index used to measure resource requirements such as bandwidth and delay of services. [0003] End-to-end service quality assurance system within the domain: the domain here includes the GPRS (General Packet Radio Service) packet domain, or the IP network such as GPRS as the access network and the IMS (IP Media Streaming Subsystem) network, PSTN Network scope for network interactions. The QoS guarantee system completes resource guarantee through policy decision and policy executio...
