Abstract
The present invention discloses a method for assigning cell resources. When a user applies cell resource for a base station according to QoS in service requests but the user service request is rejected because the current assignable resource of the base station does not satisfy the QoS requirement, the present invention does not directly reject the service request to end the resource assignment operation but continuously analyzes a priority parameter contained in the QoS of the user service request to judge whether the user service request can preempt, decelerate or queue and to correspondingly preempt, decelerate and queue by combining with the QoS requirement of the user service request; thus, the user service request can be assigned with cell resource satisfying the QoS requirement after finishing corresponding operation of preempting, decelerating or queuing. The method for assigning cell resources provided by the present invention can enhance cell access rate and user satisfaction.
Description
Technical field
The present invention relates to the wireless network resource distribution technique, be specifically related to a kind of local resource distribution method.
Background technology
In today that mobile subscriber's quantity suddenly increases, it is nervous relatively that the system resource of base station becomes.System is an example with Wideband Code Division Multiple Access (WCDMA) (WCDMA), radio communication can be carried out for guaranteeing the community user travelling carriage in the base station, will distribute the system resource that comprises transmitting power and channel code etc. to the community user travelling carriage, but these system resources are limited comparatively speaking.Along with the increase of community user, the base station system resource relative deficiency that just seems was to such an extent as to the base station system resource can't satisfy the multi-user simultaneously in order to carry out the resource requirement of radio communication.
When the user will carry out radio communication, the user can use travelling carriage to send service request by the base station to network side, after the service universal grouping wireless business supporting node (SGSN) that is positioned at core net is received this request, this request can be sent to ggsn (GGSN), GGSN can carry out the QoS negotiation to this service request.Described QoS negotiations process is: GGSN judges self whether to satisfy the qos requirement that comprises in its customer service request that receives, if can satisfy, then is that this customer service request distributes respective resources, otherwise, refuse this customer service request.
Similar therewith, after GGSN consulted through QoS, judging self can be this customer service request distribution respective resources, and after the establishment response of SGSN transmission at this customer service request, SGSN will send the response of customer service requesting activation to the base station.Establishment response and SGSN at the customer service request that described SGSN sends all include QoS to the customer service requesting activation response that the base station sends, and this QoS is identical with QoS in the customer service request.
At this moment, the base station is just carried out different disposal according to its other resources situation to service request from user.Concrete processing method is: if the current resource situation in base station self can satisfy the qos requirement that the customer service request is comprised, then send the response of customer service requesting activation to travelling carriage, distribute corresponding radio resource for travelling carriage simultaneously; Otherwise, just refuse this customer service request, said here Radio Resource is meant and comprises transmitting power and channel code etc. at interior local resource.
The flow process that the base station applies said method distributes local resource to the user as shown in Figure 1, Fig. 1 is prior art local resource allocation flow figure, this flow process specifically comprises following steps:
Step 101: the base station receives that SGSN after the activation response at the customer service request of its transmission, obtains the qos-related information that this activation response is comprised.
The QoS that activation response in this step is comprised is identical to the QoS that service request comprised that network side sends at first with the user.
Step 102: the base station judges whether self current assignable resource can satisfy the qos requirement of customer service request, if can satisfy the requirement of QoS, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, just refuse this customer service request.
As seen, the base station applies said method is when the user distributes local resource, if the base station is higher because of current resource utilization, and can't satisfy the qos requirement that the customer service request is comprised, and this customer service request will directly be refused in the base station.This resource allocation methods, cause when local resource is nervous relatively, the higher relatively service request of the qos requirement of some can be flatlyd refuse, and then causes the user can't carry out related service, reduce the access rate of sub-district, also reduced user's satisfaction.
Summary of the invention

Embodiment
In actual applications, among the QoS that service request comprised that the user sends, except comprising the message transmission time delay, the message transmission flow, speed, the packet packet loss, outside the information such as the error rate and signal to noise ratio, also comprise with this service request under the relevant priority parameters of type of service, but the point-to-point transmission of WCDMA network Special attention will be given to data, and not too pay attention to the influence that priority parameters and QoS distribute transfer of data and local resource, so described priority parameters has just had preliminary definition at present in wireless communication protocol, and does not obtain concrete utilization in actual applications.
The present invention utilizes described priority parameters just, and local resource is carried out more rational distribution.
The overall local resource distribution method of the present invention is: apply for local resource according to the QoS in its service request to the base station the user, but because the current allowable resource in base station can't satisfy qos requirement, when causing this customer service request to be rejected, not directly to refuse this service request, finish this resource allocation operations; But the priority parameters that comprises among the QoS of continuation analysis user service request, with judge whether described customer service request can seize, reduction of speed or queuing operation, and in conjunction with the qos requirement of this customer service request seize accordingly, reduction of speed or queuing operation, make this customer service request to be assigned to finish accordingly and seize, after reduction of speed or the queuing operation, can satisfy the local resource of its qos requirement.
Described priority parameters is specially: seize parameter, priority level parameter and queuing parameter.
At first, the priority level parameter is described.
Different service request is divided into different priorities according to the requirement of its type of service and QoS thereof.When two above service request need to distribute local resource simultaneously, and the current area resource is can not satisfy the resource requirement of described service request simultaneously the time, the higher relatively service request of priority can be assigned with local resource before the relatively low service request of priority; On the contrary, the relatively low service request of priority just can not be assigned with local resource before the higher relatively service request of priority.
In the practical application, different service request comprises different priority level parameter values, represents the priority height of service request with this parameter value, as: the priority level of different business request is divided into 15 grades, by 0 grade of priority to 14 grade priority, priority level reduces successively.Then, if the priority level parameter value that certain service request comprises is 1, and the priority level parameter value that another service request comprises is 9, and when these two service request were applied for local resource simultaneously, the priority level parameter value was that 1 service request will be by the priority allocation local resource.
Then, be described seizing parameter.
Whether different service request comprises the different parameters of seizing, seize parameter value and represent whether service request has the ability of seizing with different, and allow to be seized.As: 00 expression service request neither has the ability of seizing and does not allow again to be seized; 10 expression service request have the ability of seizing, but do not allow to be seized; 01 expression service request does not have the ability of seizing, but allows to be seized; 11 expression service request not only have the ability of seizing but also allow to be seized.
As seen, whether the above-mentioned first bit representation service request of seizing parameter value has the ability of seizing, and represents then whether service request allows to be seized for second.In actual applications, also can represent whether service request has the ability of seizing, and whether allow to be seized with other parameter value or other parametric form.
Suppose that service request A just has been assigned with local resource, but also do not utilize this resource to continue radio communication, and second of parameter value of seizing that service request A comprises be 1 that promptly this service request allows to be seized; Simultaneously, service request B is applying for local resource, and first of parameter value of seizing that service request B comprises be 1, and promptly this service request has the ability of seizing.
When local resource can not satisfy the resource requirement of service request B, if the local resource that service request A got can satisfy the required local resource of service request B, simultaneously, the priority level parameter value of service request B is greater than the priority level parameter value of service request A, and promptly the priority of service request B is higher than the priority of service request A.At this moment, the local resource that service request A has got will be assigned to service request B, and service request A has then lost the local resource of just having got.Described here pass through to seize parameter and carry out the operation that resource is redistributed, can be regarded as the operation of seizing of local resource.
Below, again queuing parameter is described.
Different service request comprises different queuing parameters, and different queuing parameter values then is used for representing the ability of service request aspect queuing.Suppose that the queuing parameter value is at 0 o'clock, the expression service request cannot be lined up; The queuing parameter value is 1 o'clock, and the expression service request can be lined up.So, can't be a plurality of customer service requests simultaneously during Resources allocation when the base station because resource is nervous, the customer service request that can line up in described a plurality of customer service request is formed a formation just according to priority orders, waits for that the base station is its distribution local resource; The customer service request that wherein cannot line up then is rejected.
Generally speaking, the described service request that can line up is not high to the transfer of data delay requirement, thus can be in the medium resource to be allocated of formation, and the data transmission delay that can not caused thus influences, and as: the data downloading business; The described service request that cannot line up is higher relatively to the transfer of data delay requirement, and time that can not overspending is in the medium resource to be allocated of formation, as: voice call class business.
In conjunction with above-mentioned priority parameters, can use two kinds of different local resource distribution methods and realize the object of the invention, these two kinds of methods are respectively: seize operation and queuing operation.
Below, just respectively these two kinds different local resource distribution methods are described.
At first, to described seize the operation be described.
When the base station receives that SGSN is after the activation response at the customer service request of its transmission, obtain the QoS that this activation response comprises, and analyze the priority parameters that comprises among this QoS, and other does not set up the priority parameters that comprises among the QoS of customer service request of wireless connections.If the base station draws by analysis: current activation of receiving responds pairing customer service request and has the ability of seizing, and other does not set up the customer service request that has permission to be seized in the customer service request of wireless connections, at this moment, just can seize operation.
Referring to Fig. 2, Fig. 2 seizes operational flowchart for the present invention, and this flow process specifically comprises following steps:
Step 201: judge that whether the service request that allows to be seized has got local resource, if got local resource, then enters step 202; Otherwise, seize failure, the base station current activation of receiving of refusal responds pairing customer service request.
Step 202: the local resource that the service request that the judgement permission is seized is got, whether can satisfy the qos requirement that the current activation of receiving in base station responds pairing customer service request, if can satisfy, then seize success, and then the local resource got of the service request that will allow to be seized, distribute to the current activation of receiving in base station and respond pairing customer service request; Otherwise, seize failure, the base station current activation of receiving of refusal responds pairing customer service request.
Need to prove in the step 202, to have the local resource that service request that a plurality of permissions are seized is got, can both satisfy the qos requirement that the current activation of receiving in base station responds pairing customer service request.At this moment, just therefrom select a service request that priority level is relatively low,, distribute to the current activation of receiving in base station and respond pairing customer service request the local resource that this service request is got.
Then, more described queuing operation is described.
When the base station receives that SGSN is when a plurality of activation at a plurality of customer service requests of its transmission respond, if the base station can't be these customer service requests while Resources allocation because resource is nervous, the customer service request that can line up in described a plurality of customer service request is just according to priority orders, form a formation, wait local resource to be allocated one by one; The customer service request that cannot line up then is rejected.This Fig. 3 is a queuing operation flow chart of the present invention by the queuing method of allocating resources as shown in Figure 3, and this flow process specifically comprises following steps:
Step 301: the current a plurality of customer service requests that can't get local resource and can line up, form a formation according to priority orders.In formation, the higher relatively customer service request of priority level comes before the relatively low customer service request of priority level, simultaneously, when each customer service request has just entered formation, all be that it is provided with a timer, and for timer is provided with time cycle of certain-length, same, the customer service request that newly enters formation also can come in the formation according to priority orders.
Step 302: the base station judges that current activation of receiving responds pairing customer service request and whether come first of formation, makes this customer service request can go out group Resources allocation, if can go out group Resources allocation, then enters step 304; Otherwise, enter step 303.
Step 303: judge respectively whether pairing each timer of each customer service request in the formation is overtime, if overtime, the then pairing customer service request queue failure of this overtime timer, this customer service request is refused in the base station; If do not have overtimely, then return step 302.
Step 304: the base station judges whether current allowable resource can satisfy the qos requirement of the customer service request that makes number one, if can satisfy, then line up successfully, this customer service request is just accessed troop, and be assigned with the local resource that can satisfy its qos requirement, after this, came deputy customer service request originally and just come first; If can not satisfy, then queuing failure, this customer service request is refused in the base station, and is same, after this, comes deputy customer service request originally and just come first.
Above-described seize the operation and queuing operation all relevant with the priority parameters that QoS comprised in the customer service request, except using above-mentioned seize and queuing operation distributes the local resource for the customer service request, can also use reduction of speed and be operating as the customer service request and distribute local resource.
In actual applications, the desired message transmission rate difference of the QoS in the dissimilar customer service requests, high more message transmission rate just need to distribute many more local resources.Generally speaking, when the propagation delay time of the desired message transmission rate of customer service request in satisfying its QoS requires, also there is the reduction of speed space of certain message transmission rate.After this makes that the local resource of the message transmission rate that can satisfy its qos requirement is got in described customer service request, its actual data transfer rate can not only satisfy the propagation delay time requirement among its QoS, even after being reduced to current message transmission rate to a certain degree, still can satisfy the propagation delay time requirement among its QoS.
For example: the base station is according to the message transmission rate of the qos requirement of service request A, after the travelling carriage B that sends service request A distributes local resource, message transmission rate when travelling carriage B communicates by letter with network side is the 384K bits per second, but in fact, satisfying propagation delay time among the QoS of service request A, to require pairing message transmission rate be the 128K bits per second, that is: as long as the message transmission rate of travelling carriage B when communicating by letter with network side is not less than the 128K bits per second, just can carry out proper communication.Just there is the reduction of speed space of 256K bits per second in message transmission rate when at this moment, travelling carriage B communicates by letter with network side.
At this moment, can the transfer of data minimum speed limit be set respectively, make this transfer of data minimum speed limit can just satisfy propagation delay time requirement among the QoS of customer service request at dissimilar customer service requests.Like this, if current assignable local resource can't satisfy the desired message transmission rate requirement of QoS in certain customer service request, just the desired message transmission rate of this customer service request can be carried out reduction to a certain degree, the corresponding minimizing of the local resource that it need be distributed, and finally make the current allowable resource in base station can satisfy this customer service request to reduce qos requirement after message transmission rate requires, and then make the base station distribute corresponding local resource for this customer service request.
Certainly, if message transmission rate is reduced to propagation delay time among the QoS that can just satisfy the customer service request when requiring, the allowable resource of base station still can not satisfy the qos requirement of this customer service request, the desired message transmission rate of this customer service request just can not reduce again, otherwise, even local resource has been got in this customer service request, when transfer of data, also can cause propagation delay time long, and finally cause communication normally to carry out because message transmission rate crosses low.
Above-mentioned this by the reduction of speed method of allocating resources as shown in Figure 4, Fig. 4 is a reduction of speed operational flowchart of the present invention, this flow process specifically comprises following steps:
Step 401: when the current allowable resource in base station can not satisfy the qos requirement of customer service request, and the message transmission rate that requires of this customer service request be can reduce the time, and the desired message transmission rate of customer service request is carried out to a certain degree reduction.
Reduction of speed scope in this step can be provided with voluntarily, as: between the transfer of data minimum speed limit of the desired message transmission rate of customer service request and setting, divide different speed grade.Wherein, the desired message transmission rate of active user's service request is the flank speed grade, and the transfer of data minimum speed limit of described setting then is the minimum speed limit grade; Between the highest and minimum speed limit grade, then by speed from high to low, divide a plurality of speed grade respectively.
In the time will carrying out reduction of speed, just can corresponding the desired message transmission rate of active user's service request be reduced to the low first-rate grade that is adjacent by the flank speed grade, promptly reduce a speed grade.
Step 402: the base station judges whether current allowable resource can satisfy the qos requirement of finishing the customer service request behind the reduction of speed, if can satisfy, and then reduction of speed success, corresponding local resource is distributed for this customer service request in the base station; Otherwise, enter step 403.
Step 403: the base station judges whether the desired message transmission rate of this customer service request can continue to reduce, if can, then return step 401; Otherwise, the reduction of speed failure, this customer service request is refused in the base station.
Whether the desired message transmission rate of described customer service request can reduce, specifically be meant: the transfer of data minimum speed limit of desired message transmission rate of customer service request and setting is compared, if described message transmission rate is identical with described transfer of data minimum speed limit, then can not reduce message transmission rate again; If described message transmission rate is higher than described transfer of data minimum speed limit, then can continue reduction of speed.
In conjunction with the priority parameters that comprises in the service request, generally speaking, when local resource is nervous relatively, service request can by seize, one or more operations in the reduction of speed, three kinds of operations of queuing get local resource; Maybe can by seize, each operation in the reduction of speed, three kinds of operations of queuing gets local resource, also might get local resource by any operation.
Describe in order to distribute local resource seize operation, reduction of speed is operated and queuing operation after, now, again in conjunction with the customer service request actual might carry out seize, one or more operations in reduction of speed or the queuing operation, the allocation flow of local resource of the present invention is described in detail.
Referring to Fig. 5, Fig. 5 is local resource allocation flow figure of the present invention, and this flow process specifically comprises following steps:
Step 501: the base station receives that SGSN after the activation response at the customer service request of its transmission, obtains the qos-related information that this activation response is comprised.
The QoS that activation response in this step is comprised is identical to the QoS that service request comprised that network side sends at first with the user.
Step 502: the base station judges whether self current assignable resource can satisfy the qos requirement of customer service request, if can satisfy, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 503.
Step 503: the base station obtains the qos requirement of customer service request from described activation response, and analyzes the priority parameters that comprises among this QoS, and the priority parameters that comprises among the QoS of other current customer service request of not setting up wireless connections.If the base station draws by analysis: current activation of receiving responds pairing customer service request and has the ability of seizing, and other does not set up the customer service request that has permission to be seized in the customer service request of wireless connections, at this moment, just can seize operation.
Step 504: the base station makes the following judgment by the qos requirement of each customer service request of analysis and priority parameters wherein:
Have the ability of seizing if the current activation of receiving in base station responds pairing customer service request, and other does not currently set up the customer service request that has permission to be seized in the customer service request of wireless connections, then can seize operation;
Can reduce if the current activation of receiving in base station responds the desired message transmission rate of pairing customer service request, then can carry out the reduction of speed operation;
If the current activation of receiving in base station responds pairing customer service request and can line up, the operation of then can ranking.
Because generally speaking, customer service request may have seize, a kind of ability in the reduction of speed, three kinds of abilities of queuing, or have wherein multiple ability simultaneously; And have the difference of respective capabilities, make that after above-mentioned judgement is finished in the base station corresponding operating that the customer service request is carried out also can be different.
If by judging, the base station learns that current activation of receiving responds that pairing customer service request can be seized, reduction of speed and queuing operation, then enters step 505;
If by judging, the base station learns that current activation of receiving responds that pairing customer service request can be seized and the reduction of speed operation, then enters step 511;
If by judging that the base station learns that current activation of receiving responds pairing customer service request and can seize and queuing operation, then enters step 515;
If by judging that the base station learns that current activation of receiving responds pairing customer service request and can carry out reduction of speed and queuing operation, then enters step 519;
If by judging that the base station learns that current activation of receiving responds pairing customer service request only to seize operation, then enters step 523;
If by judging, the base station learns that current activation of receiving responds pairing customer service request only to carry out the reduction of speed operation, then enters step 525;
If by judging that the base station learns that current activation of receiving responds pairing customer service request only with the operation of ranking, and then enters step 527.
Step 505: seize operation.
Step 506: judge whether successfully to seize operation, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 507.
Step 507: carry out the reduction of speed operation.
Step 508: judge whether the reduction of speed operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 509.
Step 509: the operation of ranking.
Step 510: judge whether queuing operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise this customer service request is refused in the base station.
Step 511: seize operation.
Step 512: judge whether successfully to seize operation, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 513.
Step 513: carry out the reduction of speed operation.
Step 514: judge whether the reduction of speed operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise this customer service request is refused in the base station.
Step 515: seize operation.
Step 516: judge whether successfully to seize operation, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 517.
Step 517: the operation of ranking.
Step 518: judge whether queuing operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise this customer service request is refused in the base station.
Step 519: carry out the reduction of speed operation.
Step 520: judge whether the reduction of speed operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise, enter step 521.
Step 521: the operation of ranking.
Step 522: judge whether queuing operation is successful, if success, then this customer service request is got permission in the base station, and distributes corresponding local resource for it; Otherwise this customer service request is refused in the base station.
Step 523: seize operation.
By flow process described in Fig. 5 as can be seen, if distributing the customer service request of local resource can carry out reduction of speed, current needs operate the operation of also can ranking, then at first carry out the reduction of speed operation, when the customer service request can't be got the local resource that satisfies its qos requirement by the reduction of speed operation, the operation of ranking again.This operating sequence can make the base station that allowable resource is arranged, but can't satisfy the qos requirement of customer service request the time, and the customer service request can be by the reduction of speed operation of at first carrying out, and gets the local resource that can satisfy the qos requirement behind its reduction of speed as early as possible.
But, do not have allowable resource if the base station is current at all,, can not get the local resource that can satisfy the qos requirement behind its reduction of speed yet even then the reduction of speed operation of big degree is carried out in this customer service request again, like this, this customer service request will be refused by the base station; But, if at this moment by queuing operation, when taking turns to this customer service request and go out team application resource, the base station allowable resource might become the qos requirement that can satisfy this customer service request, and then this customer service request just can be got the local resource that can satisfy its qos requirement.
So current when not having allowable resource in the base station, if the current customer service request that needs to distribute local resource can be carried out the reduction of speed operation operation of also can ranking, the operation of then at first ranking is carried out reduction of speed again and is operated at all.
