Problems solved by technology

[0015] Although the above HS-SCCH-less operation mode reduces the overhead of the control channel, because the HS-PDSCH sent by the base station to the UE occupies certain physical resources, these physical resources may be shared by multiple different UEs. When many different UEs have a large amount of service data that needs to be sent by the base station, the real-time small packet service data of some UEs using the same physical resource will be delayed, thereby affecting the service quality (QoS, Quality of Service) of the service

Embodiment Construction

[0032] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] First of all, the transmission method of the real-time small packet service of the present invention is introduced in detail. In this method, the key is: the network side notifies the UE of the physical resources to monitor the HS-PDSCH through RRC signaling; - When the physical resource of PDSCH sends new service data to UE, send new service data to UE through HS-PDSCH on this physical resource; the base station determines not to use the physical resource of monitoring HS-PDSCH notified by RRC signaling to send new service to UE In the data mode, the HS-SCCH is sent to the UE, and the UE is notified of the physical resources for temporarily monitoring the HS-PDSCH.

[0034] The method provided by the present invention can be used in an FDD system, and can als...

Abstract

The present invention discloses a method for transmitting real-time small grouping service. A base station confirms whether new service data is transmitted for user end UE with the physical resource which is informed by radio resource control RRC signaling for monitoring the high-speed physical downlink shared channel HS-PDSCH. If yes, the new service data is transmitted to UE through HS-PDSCH on the physical resource which is informed by RRC signaling for monitoring HS-PDSCH. Otherwise, the UE is transmitted with physical resource which is informed by HS-SCCH for temporarily monitoring HS-PDSCH, and then UE is transmitted with the new service data through HS-PDSCH. The invention also provides a system for transmitting real-time small grouping service. According to the application of the invention, the expenditure of control signal in the transmission of real-time small grouping service can be reduced, and furthermore the problem of time delay generated when too much service data exist on a same physical resource.

Description

technical field [0001] The invention relates to mobile data communication technology, in particular to a transmission method and system for real-time small packet services. Background technique [0002] In the 3GPP R5 protocol, in order to meet the needs of high-speed mobile data services, a high-speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access) technology is proposed. This technology has the characteristics of high speed and has been rapidly promoted and applied. [0003] HSDPA downlink includes two channels: High Speed ​​Shared Control Channel (HS-SCCH, High Speed ​​Shared Control Channel) and High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High SpeedPhysical Downlink Shared Channel). Among them, the HS-PDSCH is used to carry downlink service data, the HS-SCCH carries the scheduling and control information of the HS-PDSCH, and the user terminal (UE, UserEquipment) guides the demodulation and control of the HS-PDSCH according to the decoding...
