Problems solved by technology

Since non-real-time data services will account for a large proportion in the future communication system, and the priority of real-time services is too high compared to non-real-time services, this will cause too many non-real-time service avoidance phenomena, and the interests of non-real-time users cannot be obtained. effective guarantee
4. The existing priority thinking considers limited priority factors, which cannot meet the requirements of future communication system QoS dynamic multi-index measurement, and the impact of more new factors on priority needs to be considered
However, the future mobile communication system will be more complex, and there will be more factors affecting the priority

example 1

[0216] Assume that in the queuing queue of the handover area, there is already a real-time voice call waiting for user 1 to call multiple times, and at the same time, the non-real-time handover user 2 who is downloading files moves to the handover area and also enters the handover queuing queue. Waiting to access the target cell. And at this time, there are resources released in the cell but not enough to provide both services. It is necessary to perform priority calculation according to various parameters of the two services to determine which user should be served first. The priority is calculated once per cycle, and the one with the maximum value is the optimal user.

[0217] like Figure 4 As shown, the input set collection step is performed on user 1 and user 2. The input parameter set includes average throughput, maximum transmission rate, delay, packet loss rate, and user call type. Since the service characteristic parameters do not change during the existence of the...

example 2

[0231] Assume that there is only data user 1 waiting for switching non-real-time file download in the queuing queue of the switching area, and there is no resource release in the cell during the waiting process. The network status is still not good. According to DIPC, compare the priorities of this user and the connected user 2 who is performing file download and transmission services.

[0232]

[0233]

[0234] table 3

[0235] In Table 3, there is no waiting time for the connected users. To ensure the service quality of the connected users, the initial value of the connected users at the queuing time is 5s.

[0236] The calculation method is the same as above. From the results of the user parameter table and membership degree in Table 3, the priority value of user 1 is 0.55, and the priority value of user 2 is 0.45. User 1 accesses the network, while user 2 is forced to stop data Transmit, waiting for the next cycle priority comparison. And at this moment, the call t...

Abstract

The invention discloses a method and a device for judging comprehensive priority of a mobile communication system. The method includes the following steps: service QoS parameters of each service and user call type parameters of the service are searched; static comprehensive priority of each service is calculated according to service attribute and the user call type; and dynamic comprehensive priority value of each service is obtained by calculation by combining with multi-aspect factors such as network, service and user. According to the network condition, the algorithm of static or dynamic comprehensive priority is properly selected as the judgment basis of the service access service. The method and device for judging comprehensive priority of the mobile communication system provided in the invention comprehensively considers multi-aspect factors, provides and establishes static and dynamic comprehensive priority systems, and can carry out flexible and accurate tracking judgment on user service priority, thereby guaranteeing the comprehensive efficiency of the mobile communication system to be optimum and meeting the requirements of each party in the mobile communication system.

Description

technical field [0001] The invention relates to a mobile communication system priority judgment technology, in particular to a mobile communication system comprehensive priority judgment method and device. Background technique [0002] With the combination of IP and mobile communication standards, the future mobile communication system will be an all-IP transmission communication system supporting high-speed multimedia services. It will support higher information transmission rate and significantly reduce system transmission delay, and provide users with more flexible and diverse personalized services. At the same time, future mobile communication systems will have stricter requirements on QoS differentiation. Priority is an important part of QoS. In order to meet different business requirements and ensure user service quality, the system assigns service sequences to various services or different users. Especially when the system load is high, it is particularly important ...
