Background technique

5G proposes the vision of "Internet of Everything". In the context of the Internet of Things (IOT), a large number of users and machine terminals will need to be connected to base stations. At this time, in the case of limited resource allocation, a reasonable resource scheduling strategy and queuing criteria are needed to improve system performance.

At present, most of the researches on user queuing algorithms are based on certain queuing criteria to queue users and perform resource scheduling. The classic queuing algorithms include maximum CQI algorithm, round robin algorithm and proportional fairness algorithm. However, in the application of these classic queuing algorithms in ultra-intensive user scenarios, some users will occupy a large number of excellent resources by virtue of their queuing advantages, resulting in poor experience for other users, resulting in poor fairness for system users, and in queuing When the proportion of user business types is different, the classic algorithm cannot adjust the proportion of business types served through the system.

Step 2, judging whether there is a user with a VIP level in the user pair column of step 1,

If so, provide corresponding VIP level services to the user according to the user's VIP level;

If not, go to step three;

Step 3, judging whether each component carrier has resource blocks that can be scheduled in each transmission time interval TTI;

If so, then select the user who ranks first in the user queue to serve, and then proceed to step six;

If not, go to step 4;

Step 4, determine whether there is a user whose connection time is greater than the maximum connection time _tc in the user queue,

If so, then disconnect the service to the user, recalculate the value of the CQI of the channel quality of the user, and requeue, and then proceed to step 6;

If not, go to step five;

Step 5. Determine whether there is a user whose connection time is greater than the minimum connection time t _e , and the value of the average channel quality CQI of the user on the resource block RB is less than the value of the average channel quality CQI of the resource block RB occupied by the substitute user on the resource block RB Value; among them, the substitute user means the user who connects after the user disconnects,

If so, make the substitute user replace the current user, and then the substitute user re-queues and proceeds to step 6;

If not, proceed to step six;

Step 6, judging whether the waiting time of each user waiting in line is greater than the set user waiting time threshold t _wm ,

If so, then increase the value of the user's channel quality CQI and re-queue, and proceed to step 7;

If not, proceed to step seven;

Step 7, determine whether the duration of the sending time interval TTI is overtime,

If not, then enter the scheduling time of the next transmission time interval TTI, and return to step 2;

If the sending time interval TTI is overtime, the algorithm ends;

Wherein, the Qos is an abbreviation of quality of service, which means the quality of service.

Specific implementation mode two:

The difference from Embodiment 1 is that in the adaptive resource scheduling method based on user QoS requirements and queuing policies in this embodiment, the calculation of the channel quality CQI value of the requested user on different component carriers in the broadband is calculated in step 1, and Queue according to the queuing standard of the maximum CQI algorithm, and the process of obtaining the user queue is to obtain the user with the largest value of the channel quality CQI by the following formula, expressed as

In the formula, M is the total number of carriers, m represents the mth carrier, m∈M, is the user with the largest CQI value of the carrier m, and U is the total number of users in the queuing queue; then according to the maximum CQI algorithm, the user Corresponding channel quality CQI values are queued from large to small to obtain a user queue.

Specific implementation mode three:

Different from the first or second specific embodiment, in the adaptive resource scheduling method based on user Qos requirements and queuing policies in this embodiment, the users with VIP levels described in step 2 are divided into VIP1 users and VIP2 users according to the VIP level , VIP3 users and ordinary users. Users with different VIP levels have different priorities. VIP1 users have the highest priority, VIP2 users have the second highest priority, VIP3 users have the third highest priority, and ordinary users are It is a user without priority; the user’s communication service type includes four types: text service, voice service, image service and video service, and the order of the number of resource blocks RB required by the user service is that the text service is smaller than the voice service , the voice service is smaller than the image service, and the image service is smaller than the video service;

Among them, the definition of priority service form for users of different VIP levels is as follows:

The priority service form of VIP1 users is:

1) The VIP1 user has the highest priority and has the right to cut off the communication of the current user. When the VIP1 user needs to connect to the call, it will immediately search and judge the base station and carrier with the best channel quality around it, and immediately interrupt the current user who is talking , so that VIP1 users can transmit data; among them, the types of VIP1 users include: military communications or emergency warnings, emergency warnings include natural disaster forecasts, calls from military marshals, calls for combat readiness, etc.;

2) The priority service form of VIP2 users is:

VIP2 users have the second highest priority and have the right to jump in the queue and access communication first. When a VIP2 user appears at the time interval TTI of the sending time, and the VIP2 user is ranked at the back of the queue according to the queuing rules, no matter what the scheduling algorithm is , the VIP2 users who are waiting for access can be queued at the first position in the queue to access the communication. After the user completes the communication, the VIP2 user does not need to wait to directly access the communication; among them, the types of VIP2 users include: membership users, And its business does not require high real-time performance;

3) The priority service form of VIP3 users is:

VIP3 users have the third highest priority and have the right to wait in line and to access communication first. In order to ensure the QoS of VIP3 users, set the waiting delay threshold as t _w . Whether the waiting time of the VIP3 user is less than or equal to t _w , if yes, the user continues to wait in line, if not, and the user has not yet connected to the communication, the VIP3 user has the same queue jumping authority as the VIP2 user, regardless of the allocation algorithm Sorting rules, you can jump in the queue at the most priority access communication position in the queue. At this time, its priority can be regarded as VIP2, and the communication is completed in the current sending time interval TTI, and VIP3 users have priority to access communication; among them, the type of VIP3 users is VIP users of the operator;

4) The priority service form of ordinary users is:

Ordinary users have no priority, and the basic resource allocation algorithm such as the maximum CQI algorithm is used for resource allocation. If VIP users appear, ordinary users are users with the lowest priority.

When resource blocks RB are completely allocated to high-priority users, they are allocated to users with lower priority according to the queuing algorithm (maximum CQI algorithm, proportional fairness algorithm and round-robin algorithm). RS is the Resource Scheduler. Abbreviation, indicating the resource scheduler; the specific process is:

Step 21, judging whether there is a VIP1 user whose user level is the highest priority in the queuing queue to be served,

In the formula, M is the total number of carriers, 1≤m≤M, and CQIm represents the channel quality of VIP1 users on carrier m; according to the calculation result of the channel quality CQIm formula, select carrier m with the best channel quality, and use carrier m to transmit VIP1 users communication data, and disconnect the connection request of the user who is using the carrier m to transmit data, so as to meet the highest priority of the VIP1 user and the authority to interrupt the user's communication;

If not, proceed to the next step;

Step 22, judging whether there is a VIP2 user whose user level is the second-highest priority in the queuing queue to be served,

If there is a VIP2 user whose user level is the second highest in the queuing queue and needs to be served, then no matter what the scheduling algorithm criterion is, the VIP2 user is placed at the forefront of the queuing queue and waits in line;

If not, proceed to the next step;

Step two and three, judging whether there is a user level in the queuing queue that is a VIP3 user that needs to be served,

If there is a VIP3 user whose user level is the third highest priority in the queuing queue and needs to be served, then compare its queuing waiting time Tw with the set waiting threshold time tw, if Tw<tw, the user continues to be in the resource The scheduler RS performs sorting and waiting with ordinary users; if Tw>tw, the user has the same authority as the VIP2 user at this time, and like the VIP2 user, regardless of the channel quality, it can be queued to wait for the access sequence The frontmost position of , waiting for priority access communication;

If not, proceed to the third step of scheduling TTI resource blocks.

In the formula, U _on represents the total number of users that may be replaced online, U _replace represents the total number of users that may be replaced in the queuing queue, M _need represents the number of resource blocks RB required for replacement services, and CQI _m (u _on ) represents the mth resource The CQI value of the block user u _on , CQI _m (u _replace ) represents the CQI value of the mth resource block user u _replace ; Δ _replace is the set threshold value, obtained by the following formula:

In the formula, b represents the adjustment parameter of the replacement service, n _no-link represents the number of users served after the replacement service, and n _link represents the number of users served before the replacement service.
