Queue managing method in fast society selection between base stations

Abstract

The invention discloses the queue management method of the fast sub zone selection between the base stations. The information of the service sub zone measured and selected by UE at each time is fed back to the original service sub zone through the up signaling in the invented method. Whether the two sub zones belong to different base stations or not is determined through the original service sub zone. If the two sub zones belong to different base stations, then with the connection between the two base stations being built, the transmitting status and the queue information of UE are transferred. Otherwise, the base station informs the transmitting status and the queue information of UE to the new service sub zone so as to complete the fast sub zone selection between the base stations. The method reduces the complexity of UE and the bandwidth of the up signaling.

Description

technical field [0001] The invention relates to a queue management method in fast cell selection between base stations of a wireless communication system. Background technique [0002] In the high-speed data transmission of the wireless mobile communication system, due to the interface delay of the traditional wireless network controller-based scheduling architecture, the scheduling of data services is delegated to the base station to realize distributed scheduling of data services. Data services often use grouped data packets and use HARQ (Hybrid Automatic Repeat Request) technology. The UE feeds back ACK / NACK information according to the quality of the received data packets. The base station receives the ACK information and sends the next packet, and the base station receives the NACK information and retransmits the data packet. Based on the above facts, data service scheduling in the case of fast cell selection between base stations needs to solve the synchronization of ...

Problems solved by technology

In the above queue management method based on event update, after the fast cell selection event between base stations is triggered, the UE transmits the cell selection information and the related transmission state information of the UE through uplink signaling. Although the uplink bandwidth is reduced to a certain extent, it still It is necessary to transmit the relevant transmission status information of the UE through wireless uplink signaling. It is still required that all the cells in the effective concentration or the original serving cell and the new serving cell can reliably detect the uplink information of the UE, and it is also required that the UE can identify each cell. base station, which also increases the complexity of the UE

In the network-based queue management method described above, the interface delay will limit the fast cell selection between base stations
