Embodiment
To make the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
First embodiment
As shown in figure 3, the first embodiment of the present invention provides a kind of resource control method, applied to a network node, bag
Include:
Step 301, the value of the internal maintenance Resource Counter counter for the first resource currently safeguarded when network node is big
In zero and the first resource arrival moment sent without high-level business bag when, hang up the first resource;
Step 302, the network node is in the subframe where reception subframe, the first resource hung up and based on net
Monitored in the subframe for the follow-up send opportunity corresponding with the first resource that the semi-static scheduling cycle of network node determines
Operation;
Step 303, when object time has new high-level business bag to reach and judges in the corresponding selection window of object time
The resource of first resource reservation be when can carry new high-level business bag, according to being listened in the corresponding audit window of object time
Information carry out resource exclude judge;
Step 304, if the resource that first resource is preengage in the corresponding selection window of object time is excluded, hang-up is discharged
The value of the internal maintenance Resource Counter counter of the first resource and the first resource, and trigger resource gravity treatment;
Step 305, if the resource that first resource is preengage in the corresponding selection window of object time is not excluded, in target
Carve and send new high-level business bag in the resource that first resource is preengage in corresponding selection window.
In the first embodiment of the present invention, when the internal maintenance Resource Counter for the first resource that network node is currently safeguarded
When the value of counter is more than 0 and is sent without high-level business bag, continue to safeguard the first resource, that is, hang up first resource.Need
It is bright, operation counter can be to continue with, counter can also be hung up, be not especially limited herein.And network node one
Straight do monitors sensing operations, i.e., the scheduling of other network nodes is monitored in monitoring subframe of the network node in audit window
Signaling OA, measurement power and reception data;Specifically, since audit window is the dynamic window dynamic with the time, therefore this hair
The corresponding audit window of object time that signified audit window reaches for new high-level business in bright embodiment.Wherein, hang up
First resource where subframe can be used as and monitor subframe, such as when the subframe where the first resource of hang-up is in current
When in audit window, then the subframe where the first resource hung up is as subframe is monitored, i.e., network node is where first resource
Subframe on carry out snoop-operations.Further, what the semi-static scheduling cycle based on network node determined provides with described first
The subframe of other corresponding send opportunity of source can be used as monitoring subframe, for example, the subframe where the first resource hung up does not have
Have in current audit window, but with the propulsion of time, the subframe of the corresponding follow-up send opportunity of the first resource
It is possible to fall into the audit window slided in real time, then when follow-up subframe is fallen into audit window, then will falls into monitoring window
Subframe in mouthful carries out snoop-operations as subframe, i.e. network node is monitored on the subframe in audit window is fallen into.
Further, when the selection that resource need not be triggered when transmission transmission block TB on the first resource and again
Choosing, i.e., when no high-level business bag send, either high-level business bag reach and determine triggering resource gravity treatment when or high-level business bag
When reaching but judge to use the resource of other hang-up, this current first resource hung up, which continues to hang up, to be safeguarded, no
Process.
And when the new high-level business bag of judgement reaches and can continue to the object time reached using new high-level business bag
When the resource that first resource is preengage in corresponding selection window, increase the process that a resource excludes and judge the selection window
Whether interior corresponding resource can be continuing with.If corresponding with first resource in the corresponding selection window of object time arranged
Remove, then show that the resource cannot be continuing with, then discharge the first resource of hang-up and control network node to carry out resource weight
Choosing;If the resource that first resource is preengage in the corresponding selection window of object time is not excluded, show that the resource can be after
Continuous to use, then the corresponding resource being continuing with the selection window, first resource is pre- in the corresponding selection window of object time
New high-level business bag is sent in resource about.
Specifically, in the first embodiment of the present invention, step 303 includes:
Step 3031, when object time has new high-level business bag to reach, determine the new high-level business bag that reaches with
Whether the first resource of hang-up belongs to same process;Wherein, it is mainly preferential according to often bag to judge whether it belongs to same process
((LCID) is judged by level (ProSe Per-Packet Priority, PPPP) or logic channel ID.
Step 3032, if new high-level business bag is not belonging to same process with the first resource hung up, the target is determined
The resource that first resource is preengage in moment corresponding selection window can not carry the new high-level business bag and not to described
First resource processes;
Step 3033, if new high-level business bag belongs to same process with the first resource hung up, according to new height
The business packet size and service delay demand of layer service bag judge first resource reservation in the corresponding selection window of object time
Whether resource can carry new high-level business bag;
Step 3034, when the business packet size of new high-level business bag meets the first preset condition, and service delay demand
Meet the second preset condition, determine that the resource that first resource is preengage in the corresponding selection window of the object time can carry institute
New high-level business bag is stated, and resource is carried out according to the information listened in the corresponding audit window of object time and excludes to judge;
Step 3045, when the business packet size of new high-level business bag is unsatisfactory for the first preset condition, or service delay
Demand is unsatisfactory for the second preset condition, determines that the resource that first resource is preengage in the corresponding selection window of the object time cannot
The new high-level business bag is enough carried, discharges the first resource of hang-up and the internal maintenance resource of the first resource
The value of counter counter, and trigger resource gravity treatment.
Wherein, the first preset condition refers specifically to the resource distributed on first resource using maximum allowable MCS, disclosure satisfy that
The transmission demand of the business packet size of new high-level business bag, then meet the first preset condition, conversely, it is default to be then unsatisfactory for first
Condition;Second preset condition refers specifically to the service delay demand that first resource disclosure satisfy that new high-level business bag, then meets
Two preset conditions, conversely, being then unsatisfactory for the second preset condition.
Firstly the need of the first resource for determining the new high-level business bag reached with hanging up in the first embodiment of the present invention
Whether belong to same process, if new high-level business bag is not belonging to same process with the first resource hung up, determine the target
In moment corresponding selection window first resource preengage resource can not carry the new high-level business bag and need not pair
First resource carries out any processing;If new high-level business bag belongs to same process with the first resource hung up, need into one
Step judges whether new high-level business bag can be sent out in the resource that first resource is preengage in the corresponding selection window of object time
Send.Specifically, can new high-level business bag be sent out in the resource that first resource is preengage in the corresponding selection window of object time
Send what is mainly determined according to the business packet size of new high-level business bag and service delay demand etc., if the object time pair
The resource that first resource is preengage in the selection window answered can carry the new high-level business bag, it is determined that new high-level business
Bag can be sent in the resource that first resource is preengage in the corresponding selection window of the object time, and further according to
The information listened in the audit window of network node carries out resource and excludes to judge;And work as the corresponding selection window of the object time
When the resource of first resource reservation can not carry the new high-level business bag in mouthful, then show that new high-level business bag cannot
Sent in enough resources that first resource is preengage in the corresponding selection window of the object time, need the first of release hang-up at this time
Resource simultaneously controls network node to carry out resource gravity treatment at the same time, and the new high-level business bag for arrival selects new resource and associates new
Counter values.
Further, step 303 in the first embodiment of the present invention, including:
Step 3036, resource that first resource in the corresponding selection window of object time preengages is determined and based on network section
The corresponding resource of follow-up send opportunity corresponding with the first resource that the semi-static scheduling cycle of point determines is detection resource;
Step 3037, the information listened in the corresponding audit window of the object time is decoded, determines institute
State the sending next time of the dispatch instruction that is successfully decoded in audit window or under the reserve resource that sends several times;
Step 3038, judge whether the reserve resource collides with the detection resource;
Step 3039, if the reserve resource does not collide with the detection resource, the corresponding choosing of object time is determined
The resource that first resource is preengage in window is selected not to be excluded;If the reserve resource collides with the detection resource, determine
The resource that first resource is preengage in the corresponding selection window of object time is excluded.
As shown in figure 4, the first embodiment of the present invention determines detection resource first, detection resource includes two parts resource,
A part of resource is:Resource of the first resource correspondence of hang-up in selection window is (i.e. in the corresponding selection window of object time
The resource of first resource reservation);Another part resource is:First money of the hang-up that the fixed cycle according to first resource determines
(what i.e. the semi-static scheduling cycle based on network node determined is corresponding with the first resource for the resource of the follow-up send opportunity in source
The corresponding resource of follow-up send opportunity).Secondly, reserve resource is determined, reserve resource is:According to monitoring in audit window
The reserve resource for other nodes that the information listened on frame decodes.Finally, judge reserve resource whether with monitoring resource
Collision is sent, i.e., whether the follow-up first resource of other nodes reservation collides with monitoring resource in audit window.It is if described
Reserve resource does not collide with the detection resource, determines the money that first resource is preengage in the corresponding selection window of object time
Source is not excluded;If the reserve resource collides with the detection resource, determine in the corresponding selection window of object time
The resource of first resource reservation is excluded.
Further, judge whether the reserve resource is sent out with the detection resource described in the first embodiment of the present invention
After raw collision, the method further includes:
Step 306, if reserve resource collides with the detection resource, determine in the corresponding selection window of object time
The resource of first resource reservation is excluded;
Step 307, if reserve resource does not collide with the detection resource, determine the detection resource in object time
The resource of the counting smooth that needs to do work in corresponding audit window, and the resource to being used for power smooth in audit window is done linearly
Power smooth, obtains smooth power;If the smooth power is less than predetermined threshold value, the corresponding selection window of object time is determined
The resource of interior first resource reservation is not excluded;If the smooth power is more than or equal to predetermined threshold value, when determining target
The resource that first resource is preengage in corresponding selection window is carved to be excluded.
Further, can be further if do not collided by the first resource that the above process determines to hang up
Judged by the way that the energy smoothing process of the first resource of hang-up is further, and a general power thresholding is set, if smoothly
Power afterwards exceedes thresholding, then it is assumed that needs the gravity treatment that starts out at once;If it is not above thresholding, then it is assumed that can be continuing with providing
Source.Item Smoothing at intervals of 100ms, the window of Item Smoothing can be all resources in audit window, can also be into one
Step be reduced into resource hang up the moment after terminate to audit window before resource.
As shown in figure 5, the first embodiment of the present invention is used for work(firstly the need of definite detection resource in audit window
The resource of counting smooth, the process is compared with process, granularity 100ms;Secondly to the resource in audit window for power smooth
It is smooth to do linear power, obtains smooth power;Further judgement is finally done to smooth power, one power threshold of increase is sentenced
It is fixed.If the power after smooth exceedes predetermined threshold value, then it is assumed that first resource is excluded, then needs the resource weight that starts out at once
Choosing;If the power after smooth is not less than predetermined threshold value, then it is assumed that first resource is not excluded, then be continuing with the resource into
Row business packet is sent.
Further, in the above embodiment of the present invention, step 3037 includes:
Step 30371, if in the initial time of the corresponding audit window of the object time at the time of hanging up first resource
Before, all information listened in the audit window of the network node are decoded, determines institute in the audit window
Have the sending next time of the dispatch instruction that is successfully decoded or under the reserve resource that sends several times.
Alternatively, step 30372, if in the starting of the corresponding audit window of the object time at the time of hanging up first resource
After moment, and hang up first resource at the time of before the finish time of the audit window, in the audit window from
Start to the information listened between the finish time of audit window to be decoded at the time of hanging up first resource, determine successfully
Decoded dispatch instruction sending next time or under the reserve resource that sends several times.
For example, the time for setting audit window a length of 1s;As shown in fig. 6, at the time of first resource is hung up apart from it is current when
Quarter is more than 1s, and m moment business packet reaches, judge to use corresponding resource of the first resource of hang-up in selection window when
Wait and exclude to judge, it is necessary to carry out the corresponding resource resource;All resources of judgement audit window are needed at this time.If the hang-up
Corresponding resource of the first resource in selection window be excluded, then discharge the first resource, then trigger gravity treatment immediately;If should
Corresponding resource of the first resource of hang-up in selection window is not excluded, then can be continuing with the resource.
As shown in fig. 7, being less than 1s apart from current time at the time of first resource is hung up, m moment business packet reaches, and judges
When can using corresponding resource of the resource in selection window hung up, it is necessary to the first resource of the hang-up in selection window
Corresponding resource in mouthful carries out resource and excludes to judge.Before hanging up the moment in view of resource, node has done reliable reservation, here
Determination processing can be simplified, only the SA received after the resource hang-up moment is done and is judged.If the first resource of the hang-up exists
Corresponding resource in selection window is excluded, then discharges the first resource, then trigger gravity treatment immediately;If the first money of the hang-up
Corresponding resource of the source in selection window is not excluded, then can be continuing with the resource.
Explanation is needed further exist for, the semi-static scheduling cycle based on network node is determining with the first resource pair
The follow-up send opportunity answered is:In the multiple send opportunity that the first resource determines, positioned at the corresponding choosing of the object time
Select the send opportunity after window;Alternatively, the semi-static scheduling cycle based on network node is determining with the first resource pair
The follow-up send opportunity answered is:Determined after the multiple send opportunity that the first resource determines according to semi-static scheduling cycle
Send opportunity again.
Specifically, when the first resource that network node is currently safeguarded includes just passing resource and one or more parts retransmission resource
When, judge just to pass whether resource and one or more parts the retransmission resource corresponding resource in selection window are arranged respectively
Remove;
When corresponding any a resource is excluded, it is determined that first biography resource that release first resource includes and all
Retransmission resource, and the value of the internal maintenance Resource Counter counter of the first resource, and trigger resource gravity treatment;When right
When all resources answered are not excluded, it is determined that new high-level business bag is sent in corresponding resource.
I.e. if the resource currently safeguarded is 1 part of resource, i.e., data block is only sent 1 time, then needs to do 1 judgement;If
The resource currently safeguarded is more parts of resources, i.e., data block is sent multiple, including resource and multiple retransmission resource are passed at the beginning of 1 time, then is needed
Same decision process is done to just biography resource and retransmission resource;No matter need to exclude 1 part of resource or more parts of resources, all immediately
More parts of resources are discharged, new resource is selected for the new high-level business bag and associates relevant counter values.
To sum up, the first embodiment of the present invention provide resource control method in, when network node currently safeguard first
When the value of the internal maintenance Resource Counter counter of resource is more than zero, if being sent without high-level business bag, first money is hung up
Source, when new high-level business bag reaches, if new high-level business bag can hang-up the first resource in selection window
Sent in interior corresponding resource, increase by one to the resource whether with other reserve resources collision judgement, if do not collided,
The resource can be continuing with, then be continuing with the resource;If collision, the resource cannot be continuing with, then release should
Resource triggers gravity treatment immediately at the same time;On the premise of gravity treatment probability is not dramatically increased, the collision rate of system is reduced, business is improved and passes
Defeated reliability.
