Carrier distribution method

Abstract

The invention provides a carrier distribution method, which comprises the following steps of: grouping carriers for data services in a cell according to service characteristics of large data volume users and small data volume users in cell word counted data on the basis of a user type of a configuration carrier by a network side to obtain a large data volume user carrier group and a small data volume user carrier group; after user equipment (UE) accesses a network, determining whether the type of the UE is the large data volume user or the small data volume user according to the service volume of uplink services and the service volume of downlink services of the UE within a preset time period; when the UE is the large data volume user, taking the carriers of the large data volume user carrier group as the configuration carriers of the UE; and when the type of the UE is the small data volume user, taking the carriers of the small data volume user carrier group as the configuration carriers of the UE. The method is favorable for enhancing carrier level whole throughput amount of the system.

Description

technical field [0001] The present invention relates to the carrier allocation technology in the mobile communication system, in particular to a carrier allocation method in the TD-SCDMA system. Background technique [0002] At present, from the perspective of data volume, data service users in the TD-SCDMA system can be divided into two categories, namely users with large data volume and users with small data volume. Mainly focus on handheld data terminal users. The needs of netbook users are high data rate services, such as file download, email sending, web browsing and other services, and the needs of handheld data terminal users are small data rate services, such as QQ, MSN, stock trading software, Fetion and other services. From the forecast point of view of the business model of the existing data network, the number of handheld data terminals will be relatively large. [0003] However, in the existing scheduling process, the user resource allocation mechanism on the ...

Problems solved by technology

[0003] However, in the existing scheduling process, the user resource allocation mechanism on the network side does not distinguish between users with large data volumes and users with small data volumes. That is to say, users with small data volumes and users with large data volumes are scheduled on the same carrier. This will lead to the following problem: Since the priority of each user is usually determined according to the size of the traffic requested by the user in the current scheduling scheme, the priority calculated by the user with a small amount of data will be relatively low, which will inevitably lead to small data volume. There are fewer scheduling opportunities for high-volume users, which reduces the QoS service level of users

However, in the TD-SCDMA system, due to the limited number of code channel resources and the small number of control channels, the number of users that can be scheduled at the same time is small. Correspondingly, the optimization of the scheduling strategy cannot be used to overcome the large data The above-mentioned problems caused by the different business characteristics of high-volume users and small-volume users
