Problems solved by technology

[0016] In order to solve the problem that some terminals will not be scheduled for a long time and reduce the data transmission rate of users when the service load is heavy, the embodiment of the present invention provides a method for triggering a data transmission failure indication during communication. The base station receives After the MAC-e (Media Access Control-e) PDU (Protocol Data Unit) from the terminal, the MAC-e PDU is demultiplexed to form a MAC-d flow, including:

Embodiment Construction

[0041] Since the timeout of the retransmission timer can reflect the heavy service load on the current corresponding physical resource, the embodiment of the present invention provides a reference E-DCH MAC-d The method of triggering the NodeB to send a HARQ failure indication when the flow retransmission timer expires, and notifying the SRNC of the relevant situation. Based on this consideration, the reason for sending the failure indication is added in the HARQ failure indication message: the number of retransmissions reaches the defined maximum number of retransmissions Or the retransmission timer expires, and the SRNC performs corresponding processing according to the received HARQ failure indication: if the failure reason indicated in the failure indication is that the number of retransmissions reaches the maximum number of retransmissions, the SRNC starts the corresponding outer loop power control process; if the failure reason If the retransmission timer expires, process...

Abstract

The invention discloses a method and a device which are used for triggering data transmission failure indication in communication and aims at solving the problems that certain terminals cannot be scheduled for a long time and consequently user data transmission speed is lowered under heavier business load. The method comprises the following steps: a MAC-d stream retransmitting timer of an uplink enhanced dedicated channel is monitored; and when MAC-e PDU decoding of a hybrid retransmission requesting process is failed and simultaneously the MAC-d stream retransmitting timer of the uplink enhanced dedicated channel times out, a base station sends an indication message of failed hybrid retransmission request to a wireless network service controller. By adopting time-out of the retransmitting timer as a triggering condition of indication transmission of HARQ failure, the method and the device can notify SRNC with heavier business load situation in due time, lead SRNC to carry out reasonable business adjustment and user admission control, and consequently achieve the goal of equalizing and lowering the business load.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for triggering data transmission failure indication during communication. Background technique [0002] In order to support high-speed data services, currently in the 3GPP (3rd Generation Partnership Project, Third Generation Partnership Organization) Release 5 and Release 7 specifications, respectively proposed high-speed downlink packet access service (HSDPA) and high-speed uplink packet access service (HSUPA ), all users share all code channel resources. Through adaptive coding and modulation (AMC) and hybrid request retransmission (HARQ) technology, a higher rate is allocated to user terminals with good channel environment, and a lower rate is allocated to user terminals with poor channel environment. [0003] Among them, for the HSUPA system, the transmission channel used to carry high-level data is the uplink enhanced dedicated channel...
