A resource allocation method and device

Abstract

The present invention relates to a method and device for resource allocation, which are used to allocate FACH resources for carrying signaling on the UE's DCCH and DTCH for a UE, and improve the number of UEs accessed by the cell while ensuring the FACH transmission quality of the cell quantity. The method of the present invention includes: when a user equipment UE in the forward access channel state of a cell accesses the cell for the first time, determining the maximum number of UEs allowed to be carried by the forward access channel FACH of the cell, and the number of UEs that the cell has currently accessed number of UEs; when the number of UEs currently accessed by the cell is less than or equal to the maximum number of UEs allowed to be carried by the FACH of the cell, allocate the FACH resources of the cell to the cell forward access channel state and A UE that accesses a cell for the first time.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method and device. Background technique [0002] In a time division (Time Division, TD) system, when a user equipment (UE) initially accesses a cell, the system will assign the UE to bear the signaling on the UE channel according to the current state of the UE. channel resources. [0003] When the UE is in the cell_dedicated channel (CELL_Dedicated Channel, CELL_DCH) state, the system allocates DCH resources for the UE to carry signaling on the channel of the UE; [0004] When the UE is in the cell_forward access channel (CELL_Forward Access Channel, CELL_FACH) state, the system allocates FACH resources for the UE to carry signaling on the channel of the UE; wherein, the forward access channel (Forward Access Channel) Channel, FACH) is mainly used to carry the common control channel (Common ControlChannel, CCCH) of the cell, the dedicated control channel ...

AI Technical Summary

Problems solved by technology

In a cell with a high signaling load, the FACH of the cell usually carries a lot of signaling on the CCCH. Since the number of signaling that can be carried on the FACH is limited, while ensuring the channel quality, the FACH is used to carry the DCCH of the UE. The channel resources for signaling on the FACH and DTCH will be limited; at this time, if the number of UEs accessed by the cell reaches the maximum number of UEs allowed to be carried by the FACH of the cell, the number of signaling carried on the FACH may exceed The maximum number of signaling that can be carried on the FACH, and the priority of the CCCH is higher than that of the DCCH and DTCH, which will further lead to an overload of the signaling on the DCCH and DTCH carried on the FACH, which will reduce the transmission performance of the FACH , which in turn affects the data transmission on the DCCH and DTCH. Among them, when the data transmitted on the DCCH of the UE is affected, it will cause abnormalities in the signaling plane of the UE. The performance of the network key performance indicator (KeyPerformance Indicator, KPI) is reduced; when the data sent on the DTCH of the UE is affected, it will lead to a decline in the service quality of the UE business plane, such as the phenomenon that the mobile phone cannot access the Internet, etc.

[0007] To sum up, in the process of allocating channel resources for the UE to carry signaling on the UE channel using the existing technology, the maximum number of UEs allowed to be carried by the FACH of the cell is pre-configured by the system, and the cell The number of signaling that can be carried on the FACH is limited, which will lead to the overload of the signaling on the DCCH and DTCH carried on the FACH, which will affect the data transmission on the DCCH and DTCH
