Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] According to the utility characteristics of the three different services in the prior art, the present invention proposes a system resource allocation method that can effectively guarantee the QoS of various service users and improve service utility performance: firstly, each service including soft QoS The overall scheme of system resource allocation for multi-service transmission is given, and then according to the soft outage value and the judgment criterion of soft outage (Soft Outage) applicable to various business combinations, the remaining System resources are reasonably allocated to soft QoS service users and best-effort service users in order to further improve user utility performance and reduce allocation interruption probability during multi-serv...

The invention relates to a multi-service transmission resource allocation method supporting service containing soft service quality, which is used for a mobile communication system. A transmitting terminal comprehensively considers about channel quality information feedback by all receiving terminals in a comprehensive way and expresses the utility characteristics of all services of the service satisfaction degree requested by the receiving terminals; multi-service transmission system resource allocation general scheme is provided for all the services including soft QoS service; and then, according to soft broken value and soft broken judgment standard which is applicable to multiple service combinations, the rest system resource is reasonably allocated to the soft QoS and the service subscribers as much as possible respectively based on the hard broken judgment standard and the soft broken judgment standard, so that the utility performance of the subscribers can be further improved, and allocation broken probability in the process of multi-service transmission is reduced. The method effectively reduces the service allocation broken probability, guarantees the QoS demands of all the services, and increases the transmission speed and the utility value of the subscribers of all the services; furthermore, the operation steps are simple and convenient, implementation is easy, and the method can meet the requirements of real-time high speed data service transmission.
Description
technical field [0001] The invention relates to a resource allocation method used in a mobile communication system to support multi-service joint transmission including Soft QoS services, and belongs to the technical field of wireless communication. Background technique [0002] In today's information age, people hope to enjoy communication services with high-speed seamless coverage anytime, anywhere. The rapid development of wireless communication technology and the Internet has made it possible to realize people's wishes. However, compared with the wired network, although the wireless communication network can make users more free and convenient, the system resources (such as power, carrier, time slot, etc.) are very limited, so it is necessary to allocate resources reasonably to various services, Improve resource utilization and ensure service quality QoS for receiving end users. [0003] On the other hand, at present, people's needs for service types are becoming more ...
