Description
Technical field
The present invention relates to the communication technology, relate in particular to a kind of wireless resource allocation methods and device.
Background technology
At present, under situation such as major natural disasters rescue and relief work, urgent sudden public accident, big assembly, can occur the calling of a large amount of bursts usually, cause network congestion easily; If can't distinguish important persons such as ordinary person and movable commanding in wireless network side, just cause to provide for important persons such as movable commandings the protection of allocation of radio resources aspect; Under the situation of network congestion, the public wireless service of important persons all will be seriously influenced at aspects such as access and bandwidth safeguards.
At present aspect user radio Resource Allocation in Networks mode; The higher responsible consumer of wireless system processing priority is the same with domestic consumer; Do not distinguish, especially insert on the link the user, responsible consumer is the same with the authority of other low end subscribers; Under the situation of Radio Resource anxiety, fight for nervous Internet resources jointly with domestic consumer.When accident takes place; Owing to have a large amount of bursts of traffic; Thereby cause serious Radio Resource congested; Being seized and resource is released by other users may appear in access procedure in responsible consumer, and perhaps owing to there are not Internet resources to cause access failure, this must influence the normal access of being badly in need of the responsible consumer that Radio Resource inserts to a certain extent.
And for the user who is linked into network,,, in fact do not accomplish sufficient assurance for the service quality of responsible consumer owing to can't distinguish user type according to the wireless resource allocation methods that provides in the present radio resource management techniques yet; Present wireless resource allocation methods mainly contains:
1) max carrier to interference dispatching algorithm (Maximum Carrier to Interference; MaxC/I); All are linked into the user of network, sort according to the reception signal C/I predicted value of user UE, and carry out wireless resource allocation according to order from big to small;
2) repeating query algorithm (Round Robin; RR), all are linked into the user of network, the Radio Resource that takies equal time according to certain sequential loop of confirming communicates; Guarantee to distribute the resource of identical size to give each user in the system with the chance that equates as far as possible; Fully guaranteed whole users' fairness, but throughput of system is normally minimum, nor distinguishes the priority that the height end subscriber takies Radio Resource;
3) direct ratio fair algorithm (Proportional Fair; PF), distribute a corresponding priority level to each user who has inserted, priority is that the maximum traffic transmission rate put sometime according to the user and the ratio of this user average traffic speed before this time point define; Like this in a plurality of users' system is arranged; During user's continuous communiction, its average traffic speed increases its priority of back gradually and will diminish, and follow-up can't the acquisition served.So just guarantee the user that channel quality is good in sub-district exclusive resource always, improved user's fairness.
More than three kinds of algorithms mainly be to consider from all users' the fairness and the aspects such as throughput of whole system, but not do not distinguish to the service quality of special user and domestic consumer aspect.
Therefore, when emergency case occurring and cause local resource not enough, the higher user of priority possibly seized and resource is released by other domestic consumers in access procedure, or because does not have Internet resources to cause access failure.And after being linked into network, existing allocation of radio resources dispatching method also is that fairness and throughput two aspects of system between the collateral security user are considered, can not guarantee the service quality of priority high user.

Embodiment
The embodiment of the invention provides a kind of wireless resource allocation methods and device, for each user distributes priority, and when user access network, is preferably the high user of priority and distributes radio channel resource, thereby ensure the higher quality of services for users of priority.
As shown in Figure 1, the wireless resource allocation methods that the embodiment of the invention provides comprises:
Step S101, confirm user's priority according to the user profile of reporting of user;
Step S102, according to each user's priority level, confirm as the priority that each user distributes radio channel resource;
Step S103, be followed successively by each user according to priority and distribute radio channel resource.
Wherein, User profile can be user totem information; Like IMSI (international mobile subscriber sign) sign etc., also can be the out of Memory that can uniquely confirm a user or confirm one type of user, be provided with the corresponding relation of each user profile and priority in advance at network side; When the user needs access network, promptly can confirm this user's priority through user profile.
This corresponding relation can be set directly in the base station; By each base station maintenance, also can safeguard, and have when renewal to send to the base station at corresponding relation by the network element in the core net; Corresponding relation can also be set in the base station; When user's priority is confirmed at needs in the base station, send request, return corresponding corresponding relation or return User Priority by core net and confirm the result to core net.
Through this wireless resource allocation methods, guaranteed that radio channel resource can priority allocation gives the higher user of priority, and then guaranteed the quality of services for users that priority is higher.
Further, when telephone traffic is higher in the network, can stop the lower user access network of priority, thereby can guarantee that the higher user of priority obtains higher service quality in network.Concrete; Can open the Business Stream controlled function by the base station, when definite live traffice amount is higher than predefined telephone traffic threshold value, stop priority to be lower than the user access network of predefined first priority; Also can open the Business Stream controlled function by core net; When the live traffice amount of confirming the base station is higher than predefined telephone traffic threshold value, then send congested indication to this base station, the base station is after receiving congested indication; Confirm that promptly the live traffice amount is higher than predefined telephone traffic threshold value, stop priority to be lower than the user access network of predefined first priority.For example, if 0-15 totally 16 priority are set, the user that then can set priority and be 0-9 is domestic consumer, when telephone traffic is higher than predefined telephone traffic threshold value, stops these user access networks, and promptly priority is lower than 10 user and can be prevented from access network.
Further; Can also be in advance whether allow to seize the attribute of other user resources and whether allow by the attribute of other user's preempting resources for the user is provided with; When the branch timing of carrying out radio channel resource; If confirm not have idle radio channel resource to distribute to this user, then further confirm this user property whether for allowing to seize other user resources, if; Then the releasing network medium priority is lower than this user and the attribute resource for the user that allows to be seized, and gives this user with the resource allocation that discharges.
At this moment, user's PIE (Priority Information Element also need be confirmed except that confirming the User Priority according to user profile in the base station; Precedence information unit) attribute, PIE comprise preemption function indication (PCI) and allow by preemption function indication (PVI), when preemption function is designated as 1; Represent that this user property seizes other user resources for allowing, when preemption function is designated as 0, represent that this user property is not for allowing to seize other user resources; When permission is designated as 1 by preemption function; Represent that this user property is seized for allowing, when preemption function is designated as 0, represent that this user property is seized for not allowing.
Same, user's PIE attribute also both can be safeguarded by base station stored, also can be by the core network element storage system maintenance.
For the user in the access network; Then dispatch according to user PIE attribute; Because more important user's PIE attribute is set to allow preempting resources usually and does not allow to be seized, so can realize guaranteeing the user bandwidth than responsible consumer through this mode.For the user of same priority, then can adopt service dispatching, load congestion avoidance algorithm or reduction of speed algorithm to carry out control and management.And to the user of different priorities in the network; The mode that can adopt the embodiment of the invention to provide realizes reducing the business reorganization influence of wireless resource management algorithms such as above-mentioned employing service dispatching, load congestion avoidance algorithm or reduction of speed algorithm to the high user of priority as far as possible.
For the higher user of priority,, initiatively discharging the resource except that the user for guaranteeing its service quality; When needing to discharge its resource, can delay resource and discharge, concrete; For example; When because scheduling needs perhaps other abnormal conditions, when needing to cause the Release priority level to be higher than user's the resource of second priority, can start back off timer; Before back off timer is overtime, do not discharge this user's resource and network internal respective resources, after back off timer is overtime, discharge these user resources and network internal respective resources again.Simultaneously, when discharging user resources and network internal respective resources, can be according to the flow process of the release resource of routine; Send resource release request message to core net, and after receiving acknowledge message, discharge user resources and network internal respective resources, also can further directly discharge user resources and network internal respective resources; Because core net is not carried out corresponding release; Alleviate the release that in time to remedy these user resources when recovering in network congestion, promptly before core net is carried out overtime release, if in the base station unnecessary radio channel resource is arranged; Can distribute to the user and use, make this user in time obtain service.
The embodiment of the invention is also corresponding to provide a kind of radio resource allocation apparatus, and this device can be specially the base station, and is as shown in Figure 2, comprises in this device:
Order is confirmed unit 202, is used for the priority level according to each user, confirms as the priority that each user distributes radio channel resource;
Wherein, for the quality of services for users that guarantees that priority is higher, order confirms that unit 202 also is used for:
Confirm that the live traffice amount is higher than predefined telephone traffic threshold value;
Stop priority to be lower than the user access network of first priority.
If when carrying out resource allocation, there is not idle radio channel resource to distribute to this user, for guaranteeing that more important user can access preferential resource allocation, then resource allocation unit 203 also is used for:
For each user; When confirming do not have idle radio channel resource to distribute to this user; And this user property is when allowing to seize other user resources, and the releasing network medium priority is lower than this user and the attribute resource for the user that allows to be seized, and gives this user with the resource allocation that discharges.
In order to ensure the higher quality of services for users of priority, reduce the higher user's of priority cutting off rate, resource allocation unit 203 also is used for:
Be higher than the user of second priority for each priority, when needs discharge this user's resource, start back off timer, and discharge these user resources in the overtime back of back off timer.
Wherein, resource allocation unit 203 discharges these user resources in the overtime back of back off timer, is specially:
After back off timer is overtime, sends resource release request message to core net, and after receiving acknowledge message, discharge user resources; Perhaps
After back off timer is overtime, directly discharge user resources.
When resource allocation unit 203 directly discharges user resources, can further before the overtime release of core net, give this user with the resource allocation of free time, thereby make this user can in time regain service.
