Problems solved by technology

Based on the characteristics of E-DCH transmission, the probability that the E-DCH data will still be wrong after multiple transmissions will be very small. Synchronization state for corresponding judgment and processing, otherwise, if the UE has been unable to restore uplink synchronization, and does not perform appropriate processing, system resources will be wasted and system performance will be reduced

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, specific examples are given below to further describe the present invention in detail.

[0045] The present invention provides a method for reporting the synchronization / out-of-synchronization state indication of the uplink and a wireless link monitoring method, so as to perform corresponding processing after judging the synchronization / out-of-synchronization state of the uplink. The present invention mainly provides for judging the synchronization / out-of-sync state of the uplink according to the receiving and decoding of E-DCH data sent by the UE and the detection of the UE uplink data and reporting the corresponding indication, and determining the wireless status according to the synchronization / out-of-sync indication. The status of the link and the method for subsequent processing.

Abstract

The invention discloses a method for reporting an uplink synchronous / out-of-step direction, which is used for executing following judgments, wherein, the synchronous / out-of-step direction is reported by the method according to the obtained results: judging whether data received from UE in a first set time period or continuous first set times are all false in decoding; if decoding of all data is false, an out-of-step direction is reported; judging whether upward data of the UE are detected in a second set time period; if no data is detected, the out-of-step direction is reported; judging whether data transmitted by the UE is received and judging whether the data has a correct decoding, if data transmitted by the UE are received and the decoding is correct, a synchronous direction is reported. The invention also discloses a synchronous / out-of-step direction reporting device, a wireless link monitoring method and a system. According to the method, the device, and the system disclosed by the invention, upward wireless resource operating factor can be improved; meanwhile, unnecessary operations of deleting the wireless link caused by fail triggering of the wireless link can be reduced,thus improving user experience.

Description

technical field [0001] The present invention relates to wireless link monitoring technology, in particular to a method and device for reporting uplink synchronization indication (In-sync) / out-of-sync indication (Out-of-sync), and a wireless link monitoring method and device. Background technique [0002] In the third generation partnership project (3GPP, 3 rd In the High Speed ​​Uplink Packet Access technology (HSUPA, High Speed ​​Uplink Packet Access) of the Generation Partnership Project), two transmission modes are adopted, that is, a scheduled transmission mode and a non-scheduled transmission mode. At the same time, in order to transmit enhanced uplink data, an enhanced uplink dedicated channel (E-DCH, Enhanced DedicatedTransport Channel) and an enhanced uplink control channel (E-UCCH, E-DCH Uplink ControlChannel) are introduced. The two channels are multiplexed in the enhanced uplink physical Channel (E-PUCH, EnhancedUplink Physical Channel) for sending. In addition...
