Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The present invention avoids the AICH channel power from greatly increasing due to the access of too many user equipments at the same time by optimizing the NodeB side's access capture decision strategy for the UE. When the NodeB side judges whether there is UE access, control the total number N of AI non-zero (+1, -1) in the same access slot, if it exceeds the specified access number N, then the access threshold is exceeded for all energies The user equipments are sorted by energy, the first N user equipments are allowed to access, other user equipments that exceed the access threshold but ...

Abstract

This invention provides a method, a system and devices for controlling the capture of emission power of an instruction channel, in which, the method includes: receiving random access request of the current access time slot user device, selecting user devices that meeting the access condition and the quantity not higher than the assigned access number to send the allowed accessed capture instructions to the user devices, which controls the user quantity accessed at the same time in the same time slot by optimizing the access capture decision strategy of the Node B side to the UE to avoid the rising of the power of the AICH channel resulted in accessing too many user devices simultaneously and fluctuation in a large sphere.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method, system and equipment for controlling the transmission power of an acquisition indication channel in a random access process. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system uses PRACH (Physical Random Access Channel) to carry RACH (Random Access Channel) to complete UE (User Equipment, user device) random access. Usually a NodeB (base station) can provide several RACH channels, and each RACH channel has 15 access slots (Access Slot) and 16 available signature codes (Signature). When the UE needs to get in touch with the NodeB, it initiates an access request in the specified time slot. When the NodeB detects that the user equipment is connected and there are idle demodulation resources available, it will capture the indication channel on the AICH (Acquisition Indication Channel) ) to issue an access indication, and...
