Problems solved by technology

[0006] 1. Due to the use of a unified time slot ratio resource allocation method, the service rate in one direction will be limited or the service rate in both directions will be limited, such as HSUPA (High Speed ​​Uplink Paket Access, high-speed uplink packet access) carrier, the uplink direction can only access services with a maximum rate of 560k;
[0007] 2. Due to the uniform time slot ratio and balanced resource allocation method, the high-speed services in all directions will be scattered on each carrier. At this time, it is easy to have carriers because after the resources in one direction are full, the other A situation where resources in one direction are unavailable, reducing system capacity
For example, for an HSUPA carrier with a time slot ratio of 2:4, when the uplink accesses 560k services, the downlink resources also become unusable

example 1

[0084] Example 1. Resource allocation scheme and business symmetry discrimination method:

[0085] 11: When the user initially accesses, judge the service symmetry of the user according to the "RAB Asymmetry Indicator" information element of the RAB parameter in the RAB ASSIGNMENT REQUEST message: if the service is symmetrical in both uplink and downlink directions, perform step 12; if the service is single If the service is asymmetric, go to step 13. If the service is bidirectional asymmetric, go to step 16.

[0086] 12: Allocate users to carrier groups with a time slot ratio of 3:3.

[0087] 13: If the user service is one-way asymmetric downlink, go to step 14; if the user service is one-way asymmetric uplink, go to step 15;

[0088] 14: Allocate users to carrier groups with a time slot ratio of 2:4.

[0089] 15: Allocate users to carrier groups with a time slot ratio of 4:2.

example 2

[0102] Example 2. Resource allocation scheme and business feature discrimination method:

[0103] 21: When the user initially accesses, the "Maximum Bit Rate" information element of the RAB parameter in the RAB ASSIGNMENT REQUEST message knows the maximum uplink and downlink rate of the service, and judges the user's service symmetry according to the ratio of the maximum uplink and downlink rate. For specific judgments, see step 202 ;

[0104] 22: Determine the value of the uplink maximum rate compared to the uplink and downlink maximum rate, if the value is 1, go to step 23; if the value is greater than 1, go to step 24; otherwise, go to step 25;

[0105] 23: Allocate users to carrier groups with a time slot ratio of 3:3;

[0106] 24: Allocate users to carrier groups with a time slot ratio of 4:2;

[0107] 25: Allocate users to carrier groups with a time slot ratio of 2:4;

[0108] 26: During the service maintenance process, measure the 4A and 4B traffic events of the uplink...

Abstract

The invention relates to a method and a device for resource distribution under a multi-frequency range group net. The method comprises the steps of: determining and acquiring business characteristics of business at the time of initial access of user business, distributing the business onto a carrier wave group with a time slot proportion according to preset resource allocation strategies, wherein the carrier wave group is matched with the business characteristics. According to the invention, in a process of the initial access of the user business and business maintenance, the user business is distributed or adjusted onto the carrier wave group with the time slot proportion according to business symmetry and the preset resource allocation strategies, and the carrier wave group is symmetrically matched with the business; resource needs of various different business can be satisfied by adopting a resource allocation mode provided by the invention, and situations that a business rate with a unified time slot proportion is limited are avoided, and user experience is improved; and moreover, appropriate carrier wave group resources can be distributed to the users according to the distinguished up/down link symmetry of the user business to improve a utilization rate of resources and effectively increase a system capacity.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for resource allocation under multi-band networking. Background technique [0002] Currently, three frequency bands allocated to the TDD (Time Division Duplex, Time Division Duplex) system include: F frequency band 1880-1920 MHz, A frequency band 2010-2025 MHz and E frequency band 2300-2400 MHz. In the current TD-SCDMA (Time Division Synchronous Code Division Multiple Access) network, the frequency band used is the A frequency band, which is divided into 9 frequency points with a frequency bandwidth of 1.6M. Each carrier in the cell The time slot configuration of all adopts the same configuration, such as 2:4. However, with the subsequent development of the business, the F-band and E-band will be gradually used to meet the system capacity requirements. [0003] After introducing multiple frequency bands, the carrier frequency in the ce...
