Abstract
Description
technical field
[0001] The present invention relates to the technical field of mobile communication, in particular to a method for delaying FACH (Forward Access Channel) data transmission, RNC (Radio Network Controller, radio network controller) and a system. Background technique
[0002] FACH is the SAP (ServiceAccessPoint, service access point) provided by the physical layer to the MAC (MediaAccessControl, media access control) layer. The FACH can not only bear the signaling of the RRC (RadioResourceControl, radio resource control) ) send user data when the amount of data is relatively small. The data carried on the FACH is sent by the RNC to the Node B (NodeB) through the FP (Frame Protocol, Frame Protocol) frame of the Iub port.
[0003] In a mobile communication system, call initiation delay and ping packet delay are two very important parameters, and the quality of these two parameters will directly affect user experience.
[0004] When the UE initiates a call, it wi...

Embodiment Construction
[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] In order to shorten the FACH data transmission delay, the embodiment of the present invention adopts the following technical solutions:
[0028] like figure 1 shown. The RNC sets the first bit (bit) of the Spare field in the FP frame of the FACH to 1, which is used to indicate that the NodeB can perform self-scheduling. After receiving the FP frame of the FACH channel, the NodeB parses the first bit of the Spare field in the FP frame. If the bit is 1, it can schedule a time to send data by itself, thereby reducing the waiting time, shortening t...
