Problems solved by technology

[0003] According to the QCI range stipulated in the agreement (that is, 256 types of QCIs), operators will be supported in the future to configure the remaining 247 (256-9) types of QCIs. For these remaining 247 QCIs, the relevant QCI agreement does not define the above attributes of the service, or even Specify how to define. In order to ensure the quality requirements of the service and meet the Qos attributes of the service, the current scheduling algorithm needs to refer to the above attributes of the service to select the scheduling strategy. If the QCI service is expanded in the future, only the QCI identifier is given, and the above QCI is not defined. attribute, it cannot be compatible with the current scheduling algorithm, that is, the existing scheduling strategy is mainly aimed at the defined QCI business types, without considering the remaining 247 QCI services, and cannot meet the scheduling requirements of expanding QCI in future communication systems
[0004] In related technologies, only 9 of the 256 QCIs stipulated in the agreement are defined, resulting in poor QCI business scalability, which cannot adapt to the problem of poor future business scalability, and no effective solution has been proposed

Embodiment 1

[0051] Under the situation that the core network provides the description of the service type (the service type is voice service), the workflow for determining the QCI attribute parameter is as follows:

[0052] Step 301: when the UE with UEIndex=10 initially accesses, establish a service with QCI=12, ARP=1, GBR=MBR=17Kbps, which is a voice-like service, that is, the service model is basically the same as the voice service, and the scheduler saves the service The business attribute information of the business, for the specific structure of the scheduler, image 3 It is a structural block diagram of a scheduler according to a preferred embodiment of the present invention, such as image 3 shown.

[0053] Scheduler comprises: storage module 30, is used for storing business attribute parameter; Extended QCI business matching module 32, is connected with storage module 30, is used for matching the attribute parameter of expanding QCI business; Resource dispatching module 34, with...

Embodiment 2

[0063] In the case that the core network does not provide a description of the service type, the engineering process for determining the QCI attribute parameters

[0064] Step 401: when the UE with UEIndex=10 initially accesses, establish a service with QCI=12, ARP=1, GBR=MBR=17Kbps, and the scheduler saves the service attribute information of the service.

[0065] Step 402: The extended QCI service can be identified according to the QCI identifier: the service has QCI=12, which is greater than 9 and less than 255, so it belongs to the extended QCI service.

[0066] Step 403: Match the service QCI attribute parameters according to the service attribute parameters.

[0067] Step 4031: Match the service resource type in the QCI attribute parameter according to the service attribute parameter: the GBR rate is configured in the service attribute parameter of this service, so its service resource type is GBR service.

[0068] Step 4032: Match the service priority in the QCI attrib...

Embodiment 3

[0074] In the case that the core network provides a description of the service type (the service type is a video service), the workflow for determining the QCI attribute parameter is as follows:

[0075] Step 501: when the UE with UEIndex=10 initially accesses, establish a service with QCI=20, ARP=3, AMBR=5Mbps, which is a real-time video service, and the scheduler saves the service attribute information of the service.

[0076] Step 502: The extended QCI service can be identified according to the QCI identifier. The service QCI=20, which is greater than 9 and less than 255, belongs to the extended QCI service.

[0077] Step 503: Match the service QCI attribute parameters according to the service attribute parameters.

[0078] Step 5031: Match the service resource type in the QCI attribute parameter according to the service attribute parameter: the service attribute parameter of this service does not configure the GBR rate, so its service resource type is NonGBR service.

Abstract

The invention provides a scheduling method and a scheduling device for a service quality classification identification (QCI) service, wherein the method comprises the steps of acquiring the QCI of a service in a current cell; when the QCI indicates a fact that the service is an expanded QCI service, configuring the QCI attribute parameter of the expanded QCI service according to the service attribute parameter of the service, wherein the expanded QCI service is the QCI service of which the QCI index is larger than 9 and smaller than 255; and scheduling the service according to the configured QCI attribute parameter. The scheduling method and the scheduling device provided by the invention settle problems of low QCI service expandability and incapability of adapting with future service expandability caused by just nine kinds of QCIs in 256 kinds of QICs defined in related technology. The scheduling method and the scheduling device have advantages of satisfying different service requirements of different users, maximally satisfying a service expanding requirement in future communication systems and furthermore ensuring the Qos attribute of the service.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a scheduling method and device for a Quality of Service Class Identifier (QCI for short) service. Background technique [0002] In the current 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) protocol, services are usually divided into different types according to different attributes, that is, each type of service is represented by a QCI. The 3GPP agreement stipulates that there are 256 types of QCIs, but currently the agreement only defines 9 types of QCI services, and each type of QCI also provides at least one service example. In addition to giving at least one service example, it also specifies the type Attributes of business resource type, priority, packet delay budget, and packet loss rate. [0003] According to the QCI range stipulated in the agreement (that is, 256 types of QCIs), operators will be supported in the future to conf...
