Problems solved by technology

[0008] In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: for High Speed ​​Downlink Packet Access (HSDPA for short) cells, the access of the UE is limited to a certain extent
This is because this solution is considered from the perspective of the total downlink transmission power of the cell, and does not take into account the satisfaction of existing users in the HSDPA cell, which may cause the existing users in the system to get super-satisfactory services, but However, the access request of the UE of the new user is rejected

Embodiment Construction

[0024] 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.

[0025] The first embodiment of the present invention relates to a cell downlink access method. In this embodiment, UE access requests are differentiated, and non-HSDPA access requests and HSDPA access requests are separately controlled. Specifically The process is as follows figure 1 and figure 2 shown.

[0026] figure 1 It is a flowchart of a non-HSDPA access request in an HSDPA cell, that is, a flow chart of a method for admitting a dedicated channel (Dedicate Channel, "DCH") access request.

[0027] In step 110, when receiving the non-HSDPA access request from the UE, the network side judges whether the downlink non-HSDPA power meets the requirements.

[0028] Specifically, the network side judges the total transmit power P of all current non-HSDPA channel...

Abstract

The disclosed subzone down admittance method and system with NS device comprises: when receiving access request from UE, the NS handles as: if UE loaded on DCH channel, takes admittance decision according to down total emission power; if UE loaded on DCH channel, first decides whether the obtained rate sum of all HSDPA business in current HSDPA channel and the guaranteed rate sum meet pre-set condition, yes to admit the request directly; or else, decides the admittance combined with down total emission power. It benefits to control admittance efficiently.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to cell downlink access technology. Background technique [0002] With the advancement of mobile communication technology, the number of mobile users has increased rapidly, which has brought new pressure to mobile communication systems, especially higher requirements for access control technology in mobile communication systems. The access control technology is a method for controlling access of a user equipment (User Equipment, "UE") to a wireless channel in a mobile communication system. [0003] The access control technology in the mobile communication system is briefly described below. In a mobile communication system, when a UE moves in each adjacent cell, after entering a certain cell to complete location registration, the UE will reside in the cell and enter an idle state. This cell is also called the UE's current cell. district. In the idle state, if the UE performs ...
