Embodiment Construction

[0034] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0035] Based on the wireless access technology, the present invention proposes a method and a system for allocating random access frequency band resources among different cells during initial access and resource request stages of mobile terminals.

[0036] As shown in Figure 3, the method for allocating frequency resources of random access provided by the present invention includes the following steps:

[0037] S102. Broadcast a broadcast signal through a broadcast channel, where the broadcast signal includes available frequency band information, and the available frequency band information is information indicating a frequency band available for random access;

[0038] S104, the mobile terminal receives the broadcast signal and obtains available frequency band information; and

[0039] S106, the mobile terminal selects a frequency band from frequency bands ava...

Abstract

The invention relates to a method for distributing wireless network random access resource and relative system, wherein said method that distributes frequency resource comprises that: using broadcast channel to broadcast signal, with available frequency information; mobile terminal receives signal to obtain the available frequency information; mobile terminal selects one frequency to randomly access. And the method that distributes time resource comprises that: using broadcast channel to broadcast signal, with available time slit information; mobile terminal receives signal to obtain the available time slit information; mobile terminal selects one time slit to randomly access. The invention can average random access interference.

Description

technical field [0001] The present invention relates to resource allocation of wireless networks, in particular to a method and system for allocating frequency resources of wireless network random access and a method and system for allocating time resources of wireless network random access. Background technique [0002] Since 3GPP (3rd Generation Partnership Project) released the first commercial version of UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) network Realse99, members of 3GPP organization have continued to improve the network in order to obtain more network features and better network performance. The R5 version released in 2003 introduced HSDPA (High Speed ​​Downlink Packet Access) and the R6 version released in 2005 introduced HSUPA (High Speed ​​Uplink Packet Access) so that WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) wireless access performance has been greatly improved. ...
