Embodiment 1

[0109] This embodiment provides a wireless resource scheduling method suitable for wireless communication. The wireless resource scheduling method at each time interval (TransmissionTimeInterval, referred to as TTI) mainly includes figure 1 Process steps shown:

[0110] Step 101: Compare the current actual service quality of each service with the predetermined service quality lower limit corresponding to this service.

[0111] In this embodiment, according to the Quality of Service (QoS for short) requirements of each business, the QoS lower limit corresponding to the business is set for each business, and the current QoS actual situation of each business is compared with the QoS lower limit corresponding to the business. , to determine whether the current QoS of each service satisfies the QoS requirements of the service.

[0112] In this embodiment, when setting the lower limit of QoS corresponding to each service, when the current actual QoS of each service is equal to or l...

Embodiment 2

[0197] see figure 2 As shown, this embodiment provides a radio resource scheduler, which mainly includes: a service quality monitoring unit 201, an emergency service determination unit 202, a channel quality determination unit 203, an emergency dispatch service determination unit 204, and an emergency dispatch priority determination unit Unit 205 , non-emergency scheduling priority determination unit 206 , resource allocation unit 207 , and control unit 208 .

[0198] The connection relationship and working principle of each component are as follows:

[0199] The business service quality monitoring unit 201 is used to monitor the current actual QoS status of each business, and the monitoring can be real-time monitoring or TTI periodic monitoring. For more detailed working principles of the business service quality monitoring unit 201 , refer to the corresponding records in step 1 and step 101 in the first embodiment, but are not limited to.

[0200] The emergency business d...

Embodiment 3

[0215] see image 3 As shown, this embodiment provides a wireless resource scheduler, which mainly includes: a service quality monitor 301, an emergency service determiner 302, a channel quality determiner 303, an emergency dispatch service determiner 304, and an emergency dispatch priority determination A device 305, a non-emergency scheduling priority determiner 306, a resource allocator 307, and a controller 308.

[0216] The connection relationship and working principle of each component are as follows:

[0217] The business service quality monitor 301 is used to monitor the current actual QoS status of each business, and the monitoring can be real-time monitoring or TTI periodic monitoring. For a more detailed working principle of the business service quality monitor 301 , refer to the corresponding records in Step 1 and Step 101 in Embodiment 1, but are not limited to.

[0218] The emergency business determiner 302 is connected with the business service quality monitor...

Abstract

The invention relates to the communication field and discloses a wireless resource scheduling method, a wireless resource scheduler and a system thereof. The method comprises the following steps that whether current actual service quality of each service is equal to or less than a lower limit of preset service quality corresponding to each service respectively is compared so that whether there is an urgent service is determined; if there is the urgent service, the current schedulable urgent service is determined according to channel quality of each urgent service and a resource block is distributed for the current schedulable urgent service respectively according to a sequence from a high scheduling priority to a low scheduling priority; otherwise, according to the channel quality of the service in each resource block, the scheduling priority of each service in each resource block is determined; according to the sequence from the high scheduling priority to the low scheduling priority, the resource blocks are distributed to the services respectively. By using the technical method, QoS guarantee of an equilibrium service and maximization of a resource utilization rate are achieved; user application feeling and a network resource utilization rate are increased.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless resource scheduling method, a wireless resource scheduler and a system. Background technique [0002] The high-speed, low-latency communication capability provided by the broadband wireless network has laid the foundation for developing rich value-added services in the mobile environment. However, the scarcity of wireless resources and the instability of wireless channel link quality make it a very important task to improve the system capacity and spectrum efficiency as much as possible while meeting the various Quality of Service (QoS) requirements of users. Challenging tasks. Reasonable scheduling, allocation and management of wireless resources on the air interface is very important to maximize the utilization efficiency of system resources and meet business service quality requirements as much as possible. Wireless resource management is the planning and schedul...
