Description
Technical field
The present invention relates to the communications field, and especially, relate to method for managing resource, this method can be used for mobile communication system.
Background technology
Along with the evolution and the development of Communication Technique of network, the mobile communication system of a new generation must be able to be supported more voice IP (VoIP) service-user, and higher spectrum efficiency is provided, and obtains bigger power system capacity.Packet is less because the VoIP business has, packet has periodically and the real-time height, so the signaling consumption that the dispatching office of VoIP business brings is particularly important to the influence of systematic function.Simultaneously, be again a problem that presses for solution how reducing fully to utilize system resource efficiently under the prerequisite of expense.
At present, IEEE 802.16e system can provide based on dedicated channel the zone dynamic dispatching and the resource allocation methods of (or claiming resource pool) for the VoIP downlink business, promptly, marked off a specific resource zone, can carry out the channel definition to this zone, dynamically be that each VoIP downlink business distributes certain channel in this zone then.
The advantage of this method is as follows: (1) since resource assignment be with the channel id in the private resource zone as index, therefore two-dimensional space has been mapped on the one-dimensional space, thus the expense of greatly reducing;
(2) utilize enhancement mode downlink resource mapping cell (enhanced DL_MAP IE) that the VoIP business is still dispatched dynamically, kept the ability of channel self-adapting, more flexible than static scheduling;
(3) can adapt to preferably for the VoIP service rate that changes, in time adjust resource, also not have time delay;
(4) there is not the problem of resource fragmentationization.
Yet also there is following defective in this method: still there is the expense of bringing because of dynamic dispatching in (1), need carry out assigned resources at every turn;
(2) the channel number is limited in the reserved area, is 64 at present to the maximum, and the 2bits that counts reservation is 256 then interior, and flexibility is poor;
(3) channel in the reserved area need be divided assignment one by one, does not consider the VoIP business features, even if after periodically accusing by DCD (down channel description) message, still has bigger channel distribution indication expense.
At present, also have some schemes, for example, share static allocation " Sharing StickyAssignments " scheme, its purpose is to reduce signaling consumption.Sticky assignment is exactly the static allocation resource, and it can minimal overhead, is suitable for VoIP.But have surplus resources owing to share static assignment in user's quiet period, therefore propose to share static resource again, that is, between the user with static allocation resource and and BE class business (Best-Effort service) user between share its static resource.The method has taken into full account the utilance problem of expense and resource, obviously is underaction but a VoIP service-user and a BE class user binding are come the method for shared resource.
In addition, also proposed the notion of virtual channel allocation " Virtual Channel Allocation " at present, its purpose is to support to a plurality of VoIP service-users multiplexing in resource during its quiet period and in HARQ (mixing repeat requests) re-transmission.Wherein, defined the notion of pseudo channel tree, when travelling carriage has been assigned with virtual channel resources, must obtain the real resource of its distribution according to a mapped bitmap decoding; By mapped bitmap the pseudo channel that is distributed is shone upon mutually with certain current available actual channel, promptly obtain the distribution of actual channel.Do not have data to wait to send out when the user is current, then its pseudo channel does not need to shine upon.Like this, it is multiplexing that real resource can carry out on a plurality of users, thereby improved spectrum efficiency.The method is to go up current available channel situation by broadcasting actual channel tree, and broadcasting virtual channel trees and the actual channel mapped bitmap set is realized.Signaling consumption can reduce to a certain extent, and resource carries out multiplexingly between a plurality of users, but this motion can not be supported multiple transformat flexibly, has certain limitation.
In addition, the notion in VoIP service resources pond has been proposed at present in LTE, to reduce signaling consumption (feedback that comprises CQI, the resource indication in the schedule information).System is according to what of the voip user who inserts, adjust the size of the resource pool of distributing to the VoIP business semi-staticly, here, the semi-static cycle can be the long time period, or it is predefined according to statistical property, for example, at times the size of carrying out resource pool changes in the time.After given resource pool size, can be in short cycle under the constant situation of resource pool size, change the configuration of resource pool, for example, choose different RB according to certain rule.The base station does not need to indicate with long bit the resource of distribution yet when carrying out resource allocation.Yet this mode may cause the increase of complexity in the resource management, and can increase the change that some signalings are used to notify resource pool; In addition, also can reduce the flexibility ratio of scheduling and the utilance of resource to a certain extent, and under the prerequisite that reduces expense, not solve the resource fragmentation problem.
Also there is the thought of channel trees to propose in the motion of LTE, but for solving the form that the resource fragmentation problem adopts bitmap usually.
In sum, do not propose as yet at present to carry out scheduling of resource and distribution and the technical scheme that can join flexibly simply, efficiently.

If certain VoIP terminal is distributed to Resource Unit 106,107,110 in the base station, promptly corresponding node number is 21,22,23 on the resource subtree, then can be described by node 10, generate resource allocation message as shown in Figure 7, the value of field 1 is " 0000 ", expression resource subtree 1, the value of field 2 is " 01010 ", expression node number 10.The length of field 2 depends on the size of resource subtree, therefore terminal is judged the length of this field according to the size of resource subtree, thereby resolve this resource allocation message, on the resource subtree, find corresponding bottom layer node 21,22,23, according to the mapping relations of resource subtree 1 and resource tree 1, obtain corresponding bottom layer node 106,107 on the resource tree 1 again, 110, thus actual resource allocation information obtained.
Fig. 8 shows the detailed process flow process according to the method for managing resource of the embodiment of the invention.Particularly, comprise VoIP service terminal static allocation resource that enters active period and the processing procedure that sends resource allocation message to terminal among Fig. 8.As shown in Figure 8, specifically can may further comprise the steps:
Step 81 marks off a zone with the running time-frequency resource of system, and this zone preferentially is used for the VoIP business, and the configuration of sending zone size in broadcast/group broadcast message;
Step 82 is a plurality of resource units with the running time-frequency resource area dividing in the step 81, and all Resource Units are divided into some groups, the corresponding resource tree of each group, and every group Resource Unit is mapped to each leaf node on the resource tree respectively; In broadcast/group broadcast message, send the configuration information of least resource unit and grouping;
Step 83, the base station is divided into some groups with the VoIP service-user in the system, the basic logic resource unit group described in the corresponding step 81, every group of user only joins resource in corresponding set of resources; Voip user's grouping information can consult to obtain by base station and terminal;
Step 84, in each dispatching cycle, the base station is shone upon current available idling-resource on the resource tree and is constituted the resource subtree, and utilizes the resource tree sequence number, and node number and bit map are formed message, notify all terminals;
Step 85, base station be need resource the VoIP terminal after Resources allocation on its corresponding resource tree, generate resource allocation information and also write resource allocation message, then this message is sent to terminal;
Step 86, terminal is received resource allocation message and is resolved, and parses resource allocation information according to node number.
Example two
The structure of a resource tree as shown in Figure 3, a user in the VoIP service-user group 1 needs Resources allocation, if the available resources on the current resource tree NO.1 are all bottom fundamental nodes, certain user is distributed to 109,110,111 elementary cells among the resource tree NO.1 in the base station, then can be described by node 82, generate resource allocation message as shown in Figure 9, this message is made of a node number.Its value is " 1010010 ", and the expression node number is 82; Need 7 bits when carrying out resource allocation by this method and describing.
If discrete distribution appears in the available resources on the current resource tree NO.1, discrete Resource Unit need be remapped on the resource subtree NO.1, as shown in Figure 4.If the node 106,107,110,112,113,114,116 of the bottom is a current available resource among the resource tree NO.1, these resources are remapped to bottom node on the resource subtree NO.1.The resource subtree information that generates is made of three fields, as shown in Figure 6, the resource tree sequence number of field 1 expression mapping, field 2 expressions can comprise the upper layer node number of all available resources nodes, promptly, node 11, value is " 0001011 ", the position of the available resources node that field 3 is represented for bitmap, and value is " 11001011101 ", wherein 1 represent available resources, the unavailable resource of 0 representative.The bottom node of this resource subtree is the available resources on the respective resources tree, has 7 nodes, then has 27 nodes on this resource subtree, and arbitrary node number can number be represented with one 5 bit node.
If certain VoIP terminal of this group is distributed to Resource Unit 106,107,110 in the base station, promptly corresponding node number is 21,22 on resource subtree NO.1,23, then can be described by node 10, generate resource allocation message as shown in Figure 9, its value is " 01010 ", expression node number 10.Its length depends on the size of resource subtree, therefore terminal is judged the length of this field according to the size of resource subtree, thereby resolve this resource allocation message, on resource subtree NO.1, find corresponding bottom layer node 21,22,23, according to the mapping relations of resource subtree NO.1 and resource tree NO.1, obtain resource tree NO.1 and go up corresponding bottom layer node 106,107 again, 110, thus actual resource allocation information obtained.
