Abstract

The embodiment of the invention discloses a redirection method and device, relating to the field of communication, thereby realizing the redirection of a user equipment in a PCH state or a FACH state and avoiding trampling empty in redirection, increasing system capacity and service quality. The method provided by the embodiment of the invention comprises: receiving the community refresh request information transmitted in the first community by the user equipment in the PCH state or the FACH state, wherein, the PCH state comprises a community paging channel CELL_PCH and a registration area paging channel URA_PCH and the FACH state comprises a community forward access channel CELL_FACH; redirecting the user equipment to a second community or a second frequency point based on the preset strategy; transmitting the community updating response information to the user equipment, wherein the community updating response information includes the frequency point of the second community and scrambling information or the frequency point of the second frequency point.

Description

technical field [0001] The present invention relates to the communication field, in particular to a redirection method, device and system. Background technique [0002] Service layering can increase the service absorption capacity of the cell and obtain a good adaptive multi-rate (Adative Multi-Rate, AMR) voice experience. Generally, service layering can be realized through redirection. For example, the existing technology can generally migrate to a cell dedicated channel (Cell_Dedicated Channel, CELL_DCH) (F2H) through a cell forward access channel (Cell_Forward Access Channel, referred to as CELL_FACH) (F2H) direct retry decision (direct retry decision, referred to as DRD). Orientation complete. [0003] However, this redirection method in the prior art relies on the complete same coverage of the source cell and the target cell, which makes it easy to cause a void in a macro-micro networking scenario or a multi-band scenario. [0004] For example, see figure 1 , is a sc...
