Dispatch switching control method, system, user terminal and network device

Abstract

An embodiment of the invention discloses a dispatch switching control method, a system, a user terminal and a network device. The dispatch switching control method comprises the steps that UE sends upstream service data to the network device through an E-DCH and receives a receiving result message returned by the network device; NACK information responses to the receiving result message, the total number of positive acknowledgements and negative acknowledgements in a quality measurement control message issued by the network device serves as a unit, the UE conducts statistics on the total number of the received positive acknowledgements and negative acknowledgements and determines whether the total amount of NACK information in a window reaches an NACK number threshold value in a quality measurement control message; if the total amount of NACK information reaches the NACK number threshold value, the UE launches a measurement report message of a 5B incident to the network device, so that the network device does not dispatch and authorize the UE on the basis of the TEBS reported by the UE. The embodiment of the dispatch switching control method enables the network device on the side of a network to effectively and reasonably dispatch and authorize the UE.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and system for dispatching and handover control, a user terminal, and a network device. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is a third-generation wireless communication technical standard. TD-SCDMA High Speed ​​Uplink Packet Access (High Speed ​​Uplink Packet Access, hereinafter referred to as: HSUPA) is an evolution standard of the TD-SCDMA standard, also referred to as TD-HSUPA, or directly referred to as HSUPA. [0003] The TD-HSUPA communication protocol defines various communication events and their trigger conditions and reporting conditions, so that the network side can select the target cell for UE handover according to the user equipment (User Equipment, hereinafter referred to as: UE) reporting messages for various events. Currently, TD-SCDMA handover strategies mainly include handover strategies b...

Problems solved by technology

Since the TEBS value cannot fully reflect the UE's uplink service data transmission volume requirements, the TEBS value may also be small when the uplink service data transmission volume is high but the uplink BLER is also high, and the network side cannot know that the TEBS value is small The reason is that the UE does not have valid data to upload, or it is caused by the RLC data sliding window sliding slowly or not even sliding due to too many error packets.

Therefore, the network side cannot know the UE's actual uplink service data transmission volume requirements based on the TEBS, and thus may perform unreasonable or even wrong scheduling authorization on the UE based on the TEBS

If the scheduling authorization is too high, it will lead to a waste of limited network resources; on the contrary, if the scheduling authorization is too low, it cannot meet the UE's actual uplink service data transmission demand, which will affect the UE's transmission of uplink service data, thereby affecting service quality
