Problems solved by technology

[0004] TDSCDMA is a typical CDMA system, and its performance is limited by wireless resources. If the signaling and data of the above-mentioned small-traffic services are always carried on dedicated physical resources, the dedicated physical resources will be exhausted quickly, and the network will also fail. Will be in a congested state from time to time, affecting user access performance and wireless resource utilization efficiency

Embodiment Construction

[0025] The present invention provides a strategy for self-adaptive allocation of wireless resources, which specifically includes the following steps: Step 1. When data services are accessed, the initial access rate is set according to the current base station load. Carry out deceleration preemption; Step 2, for the data service that has been accessed, carry out flow monitoring at Iu interface place (Iu interface is the interface between access network UTRAN and core network CN); Step 3, according to the result of flow monitoring, Speed ​​up, slow down, or state transition for small-traffic services allocated dedicated physical resources; step 4, for CELL_PCH users, if there is data transmission, the state transition is performed, and if there is no data transmission for a long time, the user is released. The wireless resource self-adaptive allocation strategy of the present invention reduces resource congestion caused by small-flow data services, improves resource utilization, ...

Abstract

The present invention provides a strategy for self-adaptive allocation of wireless resources, which specifically includes the following steps: Step 1. When data services are accessed, the initial access rate is set according to the current base station load. Carry out deceleration preemption; Step 2, for the data business that has been connected, carry out traffic monitoring at Iu interface place; Step 3, according to the result of traffic monitoring, carry out speed-up, deceleration or State transition; step 4, for the CELL_PCH user, if there is data transmission, the state transition will be performed, and if there is no data transmission for a long time, the user will be released. The wireless resource self-adaptive allocation strategy of the present invention reduces resource congestion caused by small-flow data services, improves resource utilization, and effectively reduces network load caused by signaling.

Description

technical field [0001] The present invention relates to the technical field of wireless communication system TDSCDMA, in particular to a strategy for self-adaptive allocation of wireless resources. Background technique [0002] TDSCDMA is the abbreviation of English Time Division-Synchronous Code Division Multiple Access (Time Division Synchronous Code Division Multiple Access). In the cells of cellular communication systems such as TDSCDMA, the wireless physical resource pool consists of carrier frequency, orthogonal code and transmission time slot. In a single-carrier system, a code channel is used as the basic unit of resource allocation, and a code channel is jointly determined by an orthogonal code and a time slot. In addition to the dedicated physical channels allocated to users, the system also configures public physical channels for functions such as paging and random access. [0003] With the development of wireless communication technology and the popularization o...
