Embodiment Construction

[0050] The present invention mainly modifies the handover threshold of the user in the CELL_DCH state to increase the handover trigger probability of the user when it is determined that the cell is currently in a congested state, so that the user actively initiates a handover request to switch from this cell to another cell, thereby reducing the number of users in this cell number; or modify the cell selection / reselection parameters of users in idle mode and / or non-CELL_DCH state, and increase the threshold for these users to select this cell, thereby reducing the probability of these users accessing this cell. Wherein, the non-CELL_DCH state refers to other states except the CELL_DCH state in the connection mode, including the CELL_PCH state, the CELL_FACH state and the URA_PCH state.

[0051] With regard to the two processing schemes provided above, they will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention relates to a block control method. Judging if the section is blocked, if it is, modifying the switch threshold of user in CELL and DCH state to increase the switch trigger frequency of user; or else, returning to the step a to continue the judgment. The invention also discloses another method that, when the section is blocked, modifying the switch threshold of user in CELL and DCH states to increase the switch trigger frequency, to control the block and the switch is initialized by user with lower lost frequency.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, more specifically to a congestion control method in a mobile communication system. Background technique [0002] Congestion control is a must-have function for mobile communication systems. The mobile communication system periodically monitors the load status and congestion status of system radio resources, and provides appropriate and reasonable congestion handling solutions, so that the system can maintain a normal load status. It can be said that congestion control is an important means to improve wireless resource utilization and optimize network quality, and the quality of congestion control processing will directly affect the performance of the system. [0003] At present, the processing after cell congestion is mainly performed on the current link itself. For example, when the cell is congested, access to new links is prohibited, the transmission rate of non-real-tim...
