Description
Technical field
The present invention relates to a kind of resource integrated method and device, belong to mobile communication technology field.
Background technology
Along with wireless communication needs grows with each passing day, Radio Resource becomes precious because of its limited amount, and limited wireless frequency spectrum is divided into one group of group by multinomial technology such as time-division, frequency division, code division, space division and is separated from each other and non-interfering wireless channel by people.
TD-SCDMA system combines time-division and code division multiplexing technology, and a carrier wave is divided into multiple time slot, and uplink downlink communicates respectively in different time slots, and the resource in each time slot supplies multiple user's multiplexings by CDMA mode. TD-SCDMA adopts Orthogonal Variable Spreading Factor OVSF (OVSF:OrthogonalVariableSpreadingFactor) as spreading code, and a spreading code adopts the ovsf code of SF=16 as a basic resource unit (BRU:BasicResourceUnit). If a certain branch node of a certain spreading factor place rank is assigned with in time slot frequency spreading code division timing requirement ovsf code tree, then its father node is until all ovsf codes of root node all can no longer be used, and the ovsf code of all subtrees of this node can not be used again, therefore frequency spreading code division timing priority allocation continuous print ovsf code resource.
As shown in Figure 1, if current spreading code distribution condition is such as shown in Fig. 1 (a), then when a service access and 16 BRU resources of need, according to ovsf code tree state, assignable spreading code is the ovsf code of 4 SF=8, or the ovsf code of 8 SF=16, if but when user can only use 2 spreading codes owing to self-ability is limited, then distribute failure, i.e. service access failure. If so by the situation distribution as shown in Fig. 1 (b) or be adjusted to the situation as shown in Fig. 1 (b), then can be that this user distributes the ovsf code of a SF=2 and makes it access, such that it is able to the success rate of raising access.It addition, for the realization simplification consideration to radio resource management operations such as power control, switching controls, and user self number of time slots limited ability considers, also should be that a user distributes the resource in same time slot as far as possible.
And along with the connection of each service communication and release in reality, available ovsf code road resource presents scattered distribution, if at this moment one to the service access that resource requirement is more time, residue available OVSF codes road resource in one time slot is possible to meet its requirement, at this moment will implement resource integration. By means such as the channels that channel adjustment, compression or breaking part low priority traffice take, available ovsf code road Resource Unit is concentrated in a time slot as far as possible, idle ovsf code road resource in time slot to be accessed can be made to reach the access demand of high speed business.
In sum, resource consolidation in order that integrate continuous print free time ovsf code road Resource Block in output time slot, reduce ovsf code resource fragmentation, and then the raising resource utilization of system, business (especially high-rate service) are successfully accessed rate and handover success rate.
Traditional resource consolidation technology, determining in time integrating time slot, simply carry out priority queueing and using time slots maximum for available BRU number as the whole process of time slot to be integrated it is not intended that code blocking phenomenon, user capability and available BRU distribution situation according to the number of available BRU resource roughly, it is easily caused the generation of extra ovsf code resource fragmentation, runs counter to the original intention of resource consolidation.
It addition, when determining user to be adjusted, it does not have consider the distribution condition of spreading code shared by current user to be adjusted, producing new ovsf code resource fragmentation after resource consolidation, thus causing that resource consolidation is vibrated, integration is often, time delay strengthens, and even causes business call drop.

Detailed description of the invention
Below in conjunction with drawings and Examples, the resource integrated method of the present invention is described in detail.
As in figure 2 it is shown, the resource integrated method of the present invention, comprise the following steps:
Triggers resource is integrated;
Calculate the dispersion of the channel of each time slot in carrier wave, and select to wait to integrate time slot according to described dispersion, according to waiting that the channel dispersion state integrated in time slot determines discrete user, wherein, described dispersion is that the channel characterizing time slot is by the metric of the Discrete Distribution degree of CU BRU resource;
Treat the discrete user integrated in time slot and carry out prioritization;
Priority according to discrete user, adjusts the customer service of discrete user successively to target time slot, and discharges described customer service in the described resource treated and take in integration time slot; Wherein, described target time slot is to have the time slot of the available BRU resource of residue.
In the definition of the dispersion of channel, being once defined as by the dispersion with the time slot of the connatural BRU resource of continuous print, for congeniality, such as can will take as a kind of character, unoccupied be another kind of character.
Integrating for described triggers resource, its trigger condition can adopt event mode to trigger or preiodic type poll triggers.
Described event mode triggering mode, the i.e. current resource consolidation discharged by spread spectrum code resources or have the new business access spreading code unsuccessful triggering of distribution.
Described preiodic type poll triggering mode, the size of its activation period determines the frequency that resource consolidation starts, and cycle too small meeting triggers resource too much is integrated, and the cycle is excessive, causes that OVSF fragment can not get arranging for a long time, the resource utilization of influential system.
Dispersion for described channel, characterize the channel of time slot by the metric of the Discrete Distribution degree of CU BRU resource, its unit can represent with " degree ", there is the connatural BRU resource of continuous print for once, here congeniality is by distributing or the unallocated number of degrees representing a time slot, for TD-SCDMA system, the span of the dispersion of the channel of a time slot is [1,16]. The degree of the number of degrees more big channel dispersion distribution is more high.As it is shown on figure 3, the dispersion of the channel of this time slot is 6 degree in this diagram.
Its speed of R4 business for supporting at present is 12.2kbps, 64kbps, 128kbps and 384kbps, shared BRU number corresponds to 2,8,16 and 48, so the definition according to dispersion, for R4 business, the span of the dispersion of the channel of one time slot is [1,8].
By the concept of dispersion, describe available BRU distribution of resource situation and as the foundation adjudicated of whether implemening resource integration, unnecessary resource consolidation can be reduced, reduce unnecessary signaling consumption.
Time slot is integrated for described treating, specifically, presents Discrete Distribution and the dispersion time slot more than predetermined threshold value including the BRU resource distribution distributing to user; Wherein, Discrete Distribution state can be represented by dispersion.
When determining user to be adjusted, by Discrete Distribution state and dispersion threshold condition, not only consider the BRU resource number shared by this user, but also consider the distribution situation in ovsf code road shared by this user.
For described discrete user (i.e. user to be adjusted), specifically, including pure discrete user and half discrete user. Wherein, pure discrete user and half discrete user are that the BRU distribution of resource state shared by user is determined.
Described pure discrete user includes all BRU resources shared in the time slot user all in discrete state, and this user is the pure discrete user under this time slot; The BRU destruction Of resources shared by pure discrete user monoblock resource.
Described half discrete user includes only having part BRU resource to be in the user of discrete state, the half discrete user that this user is under this time slot in BRU resource shared in time slot; Shared by half discrete user, a portion of BRU resource destroys monoblock resource.
Can being considered as discrete user, the user namely not adjusted of other situation.
The definition of the discrete state of above-mentioned CU BRU resource, as shown in Figure 4, continuous distribution and (be set to UE by same userj) the BRU resource (assuming that continuous print BRU number is N number of) that takies, if meet following two condition simultaneously, then claiming these BRU resource state in which is discrete state.
A、BRUi, BRUi+1..., BRUi+N-1∈UEj, 1≤i≤M-N;
Wherein M represents the total value that the RBU total number resource of a time slot adds 1, and in TDSCDMA system, this value is 17. According to above-mentioned condition, then UE4 and the UE5 in Fig. 4 is pure discrete user, and UE1 is half discrete user, and UE2 and UE3 is discrete user.
By pure discrete user and half discrete user, BRU distribution of resource situation shared by user to be adjusted is described, such that it is able to for different types of discrete user, formulated different Resources Coordinating Strategies.
Select to wait to integrate time slot step according to described dispersion for described, farther include: respectively uplink/downlink time slot is carried out prioritization according to described dispersion, select that uplink/downlink time slot meets the time slot waiting to integrate time slot condition respectively according to described prioritization and be set to wait to integrate time slot; Wherein, prioritization is according to time-slot load homeostatic principle, and the slot priorities that namely available BRU number of resources is many is high.
By respectively uplink/downlink time slot being carried out prioritization, it is possible to the resource consolidation of uplink and downlink timeslot in carrier wave is independently integrated.
The described discrete user treated in integration time slot is carried out to the process of prioritization, first treat the pure discrete user integrated in time slot and carry out prioritization, then treat the half discrete user integrated in time slot and carry out prioritization.
Wherein, treat the pure discrete user integrated in time slot described in carry out the method for prioritization and include:
If multiple pure discrete CU BRU numbers are less than needed for new business during the requirement of BRU resource request, arranging the priority taking the many pure discrete users of BRU number is high priority;
If multiple pure discrete CU BRU numbers more than needed for new business during the requirement of BRU resource request, arrange and take BRU number close to the priority of the pure discrete user of BRU resource request needed for new business is high priority.
The method that the described half discrete user treated in integration time slot carries out prioritization includes:
If multiple half discrete CU BRU numbers are less than needed for new business during the requirement of BRU resource request, arranging the priority taking half many discrete user of BRU number is high priority;
If multiple half discrete CU BRU numbers require equal to BRU resource request needed for new business, in the BRU that it is shared, the priority arranging half more many discrete user of the BRU number being in discrete state is high priority;
If multiple half discrete CU BRU numbers are more than needed for new business during the requirement of BRU resource request, the priority arranging the half discrete user taking BRU resource request needed for BRU number is closer to new business is high priority.
Specifically, the priority of pure discrete user is higher than half discrete user; Wherein, if it is that high-rate service accesses the resource consolidation triggered that triggers resource is integrated, then for pure discrete user:
If multiple CU BRU numbers are less than needed for new business during the requirement of BRU resource request, then the priority taking the more many pure discrete users of BRU number is more high.
BRU number is taken equal to needed for new business during the requirement of BRU resource request, then determining User Priority according to self-defining strategy, determine with specific reference to the user of this patent if multiple.
BRU number is taken more than needed for new business during the requirement of BRU resource request, then taking the priority of the pure discrete user of BRU resource request needed for BRU number is closer to new business more high if multiple.
For half discrete user:
If multiple BRU numbers that take are less than needed for new business during the requirement of BRU resource request, then the priority taking half more many discrete user of BRU number is more high.
If multiple BRU numbers that take are equal to needed for new business during the requirement of BRU resource request, then in the BRU that it is shared, the priority being in half more many discrete user of the BRU number of discrete state is more high, if the BRU number that multiple half discrete users are in discrete state is also consistent, then can determine User Priority according to self-defining strategy, determine with specific reference to the user of this patent.
If multiple BRU numbers that take are more than needed for new business during the requirement of BRU resource request, then the priority of the half discrete user taking BRU resource request needed for BRU number is closer to new business is more high.
If it is the resource consolidation that periodically poll or code channel release trigger that triggers resource is integrated, then the discrete User Priority taking BRU number more many is more high.
As an embodiment, described, user to be adjusted is adjusted to target time slot, also include target time slot is carried out prioritization, then further according to the priority of the priority of user to be adjusted and target time slot, successively the customer service of discrete user is adjusted to target time slot.
Preferably, the process of the prioritization of described target time slot includes as follows:
Available BRU number according to target time slot from more to less target time slot is carried out prioritization; Namely first prioritization is carried out by available BRU number.
If the available BRU number of target time slot is equal, the priority arranging the little target time slot of dispersion is high priority; The target time slot being about to available BRU number equal is ranked up again.
If the dispersion of target time slot is equal, the priority arranging the little target time slot of timeslot number is high priority, and the target time slot equal by dispersion is ranked up again.
Step to target time slot being adjusted for the described customer service by discrete user, specifically, if described discrete user is pure discrete user, it is judged that whether target time slot is successfully accessed, if being successfully accessed, then this pure discrete user being adjusted to target time slot; If described discrete user is half discrete user, it is judged that whether target time slot is successfully accessed, if being successfully accessed, then calculate the dispersion of described time slot to be adjusted after adjusting, if dispersion reduces, then this half discrete user is adjusted to target time slot.
Illustrate that half discrete user waits to integrate the dispersion situation of change of time slot when adjusting below in conjunction with accompanying drawing 5, as it is shown in figure 5, half discrete user 1 is adjusted to target time slot, described time slot to be adjusted from divergence become 8 degree by 6 degree, dispersion does not reduce, then be not adjusted; Half discrete user 2 is adjusted to target time slot, described time slot to be adjusted from dispersion become 3 degree from 5 degree, dispersion reduce, then be adjusted.
By for different types of discrete user, having formulated different Resources Coordinating Strategies, it is possible to reduce unnecessary resource consolidation, reducing code fragment and produce, resource consolidation success rate is high, and then improves the rate of being successfully accessed and systematic entirety energy.
