Service class indication method, device and system

Abstract

The invention discloses a service class indication method, a service class indication device and a service class indication system, which are used for definitely classifying various increasingly more complex application services to avoid the confusion of service processing flows. The method comprises that: core network equipment transmits a service identifier for indicating a service class to access network equipment by an extension header in a general packet radio service (GPRS) tunneling protocol for a user plane (GTP-U) signal element in a downlink message, so that the access network equipment can timely determine the service class, and executes a corresponding service process operation. Obviously, the service identifier is carried by the extension header in the GTP-U signal element, so that more service classes can be supported, and the service types can be conveniently extended. Simultaneously, the GTP-U signal element does not belong to an Internet protocol (IP) transmission layer, and the modification of the bottom transmission layer is not involved in resolution. Therefore, the large-area improvement of the system may not be involved by adopting the GTP-U signal element to carry the service identifier, the realization cost is effectively saved, significant influence on system performance is avoided, and the quality of service of the system is ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for indicating service types. Background technique [0002] At present, in the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) system, only the RAB (Radio Access Bearer, radio access bearer) used when establishing the service can be used to assign the Message types (session, flow, interaction, background) and QoS parameters simply classify service types, and then perform different wireless resource scheduling according to service types. With the large-scale networking of 3G, the types of services are also more abundant, and different radio resource scheduling strategies are required for different types of services. Existing service classification methods can no longer meet the operator's requirements for service classification. [0003] In order to solve the above problems, ...

Problems solved by technology

like figure 1 As shown, in the prior art, the DSCP parameter in the IP header only contains one byte, that is, 8 bits, and the value range is limited, and many of the values ​​have been used and can no longer be used as the identification of the service type. Therefore, It is not conducive to the expansion of business types; at the same time, since the DSCP parameters are at the level of the IP transport layer, the modification of the underlying transport layer is involved in the analysis. Therefore, if the number of bytes occupied by the DSCP parameters is modified to support it to represent more business types, then The scope of the changes involved is large and will have a significant impact on the performance of the device
