Problems solved by technology

[0032] Among them, the main idea of ​​step 304 is: if the current resources cannot meet the service request initiated by the user, then adjust the resources currently running the business to meet the resource requirements of the user's new business, but how to effectively and reasonably adjust the resources of the current running business Resource situation, there is no relevant description given in the prior art

example 1

[0061] Example 1: RACS acquires adaptive QoS parameters from NASS during resource admission control

[0062] Wherein, FIG. 5 shows the signing process in the example 1 (equivalent to the above step S402), as shown in FIG. 5, including:

[0063] 501: The user signs a contract with NASS. In this process, the subscription information needs to include the adaptive QoS parameters of the service.

[0064] Fig. 6 shows the resource admission control process in the example 1 (equivalent to the above step S404), as shown in Fig. 6, including:

[0065] 601: The CPE initiates a service request, sends a request message to the AF, and triggers the AF to generate a resource initialization request;

[0066] 602: AF sends a resource request message to RACS;

[0067] 603: After receiving the resource request message, the RACS interacts with the NASS, queries the subscription information of the user, and obtains the service adaptive QoS parameters included in the information;

[0068] 604: ...

example 2

[0072] Example 2: NASS sends adaptive QoS parameters to RACS during the subscription process

[0073] Wherein, FIG. 7 shows the signing process in this example 2 (equivalent to the above-mentioned step S402), as shown in FIG. 7, including:

[0074] 701: A signing process between the user and the NASS. In this process, the subscription information needs to include the adaptive QoS parameters of the service;

[0075] 702: The NASS actively transmits the subscription information of the user to the RACS.

[0076] Fig. 8 shows the resource admission control process in the example 2 (equivalent to the above step S404), as shown in Fig. 8, including:

[0077] 801: The CPE initiates a service request, sends a request message to the AF, and triggers the AF to generate a resource initialization request;

[0078] 802: AF sends a resource request message to RACS;

[0079] 803: The RACS makes resource decisions based on the user's subscription information, which includes the adaptive Q...

Abstract

The invention discloses a control method for resource acceptance, wherein during the course when the user registers at a network adhesion subsystem, the registered information includes self-adaptive service quality parameters of business which indicate the maximum that the business resource occupancy can be adjusted by the resource acceptance control subsystem; in the course of the resource acceptance control, under the condition that the present resource can not meet the resource request of the business originated by the user, the resource acceptance control subsystem judges whether to adjust the business resource occupation to meet the resource request by the self-adaptive service quality parameters, if the judgment result is 'yes', the business resource occupation is reduced and the resource request is accepted. Otherwise, the resource request is rejected.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource admission control method for a resource admission control subsystem in a next-generation network to adaptively adjust service quality (QoS). Background technique [0002] The next generation network (Network Generation Network, NGN) adopts packet technology such as IP as the bearer network technology to integrate fixed communication and mobile communication. NGN can provide richer multimedia services, which puts forward higher requirements on the quality of service (Quality of Service, QoS) of user services. [0003] Resource admission control is a new concept introduced in NGN, which is located between the service control layer and the bearer transport layer. Through the implementation of resource admission control, the specific details of the transport network are shielded from the business layer upwards, the separation of service control and transport functions is...
