Abstract
The invention discloses a real-time service carrier resource allocation method, which comprises: base station allocates carrier resource to terminal periodically according to the service quality grade configuration parameter of service connections; if the terminal detects that the allocated carrier dissatisfied real-time service demand, it applies extra carries resources to the base station; and the base station allocates extra carrier resources to the terminal according to the requirement. The method improves allocation efficiency, and satisfied the short time delay demand of the real-time service better.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to the mobile communication system of carrying out real-time service transmission.
Background technology
In the 4th third-generation mobile communication system, for more flexible services is provided, the air resource that more efficient use is limited, system classifies miscellaneous service according to quality of service requirement, and the link that different service quality is required distributes different resources.The user need be the service chaining application carrier resource of different service quality requirement, is used to send the grouped data of concrete link.The application method of general service has multiple, the most frequently used a kind of be terminal regularly according to demand to base station application carrier resource, the carrier resource of corresponding up link is distributed according to the application of terminal in the base station.But this method can not satisfy the needs of real time business, and on the one hand, VoIP real time business such as (internet protocol voice technologies) is very sensitive to time delay, and the strategy of first to file reallocation can not satisfy the requirement of low time delay; On the other hand, general real time business is substantially invariable to the requirement of carrier resource size, there is no need by the frequent adjustment of terminal.So real time business must adopt the resource allocation policy that meets its service feature more.
Summary of the invention
The present invention is in order to overcome the defective that existing carrier wave resource allocation method can not satisfy the real time business needs, to have proposed a kind of carrier wave resource allocation method that is applicable to real time business.
For achieving the above object, the carrier wave resource allocation method of the real time business that the present invention proposes is by the following technical solutions: the base station is after the real time business of terminal distributes initial carrier resource, according to the real resource conditions of demand of terminal, carrier resource is dynamically adjusted distribution.
Further, described method may further comprise the steps:
(1) base station is the initial carrier resource of real time business link distribution of terminal;
(2) when terminal during to the carrier resource increase in demand, the carrier resource outside base station application allocation;
(3) detect when the carrier resource demand fallen after rise when terminal, informing base station is regained the extra carrier resource for its distribution.
The carrier wave resource allocation method of real time business of the present invention, wherein, in step (1), the base station is that the size of the original carrier resource of terminal distribution is to dispose according to the quality of service requirement that links.
The carrier wave resource allocation method of real time business of the present invention, wherein, the cycle that in the base station is the terminal distribution carrier resource is according to the quality of service requirement configuration of link.
The carrier wave resource allocation method of real time business of the present invention, wherein, in step (2), terminal can dispose to the size of the extra carrier resource of base station application, is set to the relative scale value of fixed carrier resource.
In order to realize the variation of terminal detected carrier resource requirement, the present invention proposes following technical scheme: terminal is applied for the extra carrier resource by the needs that relatively judge whether of transmit queue length and preset length.
Further, described method may further comprise the steps:
(1) terminal is provided with a queue length;
(2) terminal detects length of data queue to be sent greater than the queue length that is provided with, and just thinking needs the extra carrier resource of application;
(3) terminal detects length of data queue to be sent by becoming less than the queue length that is provided with greater than the queue length that is provided with, and just thinking no longer needs to apply for extra carrier resource, should regain by informing base station.
The method that terminal detected carrier resource requirement of the present invention changes, wherein, in step (1), the queue length that sets in advance is that the maximum delay parameter according to the business of weighing the chaining service quality requirement is provided with.
Adopt described method of the present invention, compared with prior art,, improved allocation efficiency of resource greatly, better met the low delay requirement of real time business by compressing unnecessary resource bid process.
