Problems solved by technology

In a cell with many instant messaging services and a cell with many media services, under the same TBFLIMIT parameter setting, the PDCH carrying efficiency will be quite different, and the user's perception will also be significantly different. The size of TBFLIMIT cannot truly reflect Utilization of PDCH
[0006] Therefore, in different service scenarios, PDCH resource allocation based on TBFLIMIT parameters cannot meet the needs of real services, resulting in unbalanced and inefficient use of network resources

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] figure 1 It is a schematic diagram of the implementation flow of a channel allocation method of a temporary block flow in the present invention, as figure 1 As shown, the method includes the following steps:

[0041]Step 101: When establishing a TBF, obtain the temporary traffic indicator TFI resource occupancy rate of the current packet data channel PDCH set of the cell, and when the TFI resource occupancy rate exceeds the set first threshold, increase the PDCH set, and transfer the The established TBF is allocated to the added PDCH set; when no PDCH set is added, the established TBF is allocated to the PDCH set with the lowest bearer efficiency;

[0042] Specifically, when adding a PDCH set, the method further includes: initially allocating one or two PDCHs to the added PDCH set.

[0043] Specifically, when the TFI resourc...

Abstract

The invention discloses a channel distribution method for temporary block flow. The method comprises the steps of obtaining the seizure rate of TFI resources of current PDCH sets of a cell when the TBF is established, adding the PDCH sets when the seizure rate of the TFI resources exceeds a set first threshold, and distributing the established TBF to the added PDCH sets; when the PDCH sets are not added, distributing the established TBF to the PDCH set with the lowest loading efficiency; adjusting the number of PDCHs in the PDCH sets according to the loading efficiencies of the PDCH sets. The invention further discloses a channel distribution device for the temporary block flow at the same time. By means of the channel distribution method for the temporary block flow and the channel distribution device for the temporary block flow, the number of the PDCHs distributed to the cell can be adjusted dynamically, the utilization rate of the wireless resources is increased, and meanwhile, the situation that a service request does not have access due to the fact that only the loading efficiency is considered is avoided.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a channel allocation method and device for temporary block flow. Background technique [0002] During a Global System for Mobile Communication (GSM, Global System for Mobile Communication) packet transmission process, a Packet Data Channel (PDCH, Packet Data Channel) is allocated in the form of a PDCH set, and the PDCH set is generally called a PSET. PDCH is the logical entity for carrying wireless packet data on the air interface. Temporary Block Flow (TBF, Temporary Block Flow) is the connection between the mobile station (MS, Mobile Station) and the network side. The MS and the network side are on the PDCH through TBF. Transport packet service data. All PDCH allocations in the PSET come from the same traffic channel (TCH, Traffic Channel) group, and a PSET can contain up to eight PDCH channels. Each MS can support up to two TBFs (one for uplink and one for downlink) at th...
