Description
Technical field
The present invention relates to the communications field, particularly relate to the distribution method of the homogeneous-frequency adjacent-domain communication resource and the resource allocation device for VAMOS system in a kind of VAMOS system.
Background technology
In 3GPP R9 standardisation process, VAMOS (full name Voice over AdaptiveMulti-user channels on One Slot: with time slot adaptive multiuser voice channel) proposes the concept of the same time slot voice user of GSM network being adopted to the multiplexing same frequency of multiple user, voice messaging by multiple user is multiplexing is launching transmission with on a time slot, terminal and base station receiver respectively by the elimination pairing interference of user and the method demodulation target information of joint-detection, thus improve the voice capacity of GSM network.Specifically, in VAMOS system, network side down direction uses QPSK (Quadrature Phase Shift Keying; Quarternary phase-shift keying (QPSK)) modulation system by two pairing users speech data be modulated on orthogonal I road and Q road respectively, and make terminal can distinguish the user matched with it by distributing the good TSC of orthogonality (training sequence code) sequence to pairing user, demodulate the data of expectation.In the upstream direction, the user that matches still adopts GMSK (Gaussian Minimum Shift Keying; Gaussian-filtered minimum shift keying) modulation system, distinguished by orthogonal TSC sequence, data sent on same time slot, base station side TSC distinguishes user, and carries out demodulation by joint-detection.
At present, voice user enjoys independent slot transmission data, and suffered interference is mainly from CCI (the Co-Channel Interference of neighbor cell; Co-channel interference) and ACI (AdjacentChannel Interference; Adjacent frequency is disturbed), the interference strength wherein produced with the co-channel interference signal of ground floor homogeneous-frequency adjacent-domain is again the strongest.In order to as far as possible effectively eliminate interference, large multiple mobile phone terminals adopts SAIC (Single Antenna Interference Cancellation; Single antenna interference cancellation) algorithm, plays good inhibition to the co-channel interference signal under GMSK modulation mode.But, in current VAMOS system, pairing user repeatedly using same time slot, the user that then matches constitutes very strong co-channel interference mutually, increase the difficulty that existing terminal eliminates co-channel interference, thus cause pairing user receptivity significantly to decline, specifically, VAMOS in homogeneous-frequency adjacent-domain matches the time slot at user place due to simultaneously for two users provide power, although gross power amplitude is generally large than the power magnitude of isolated user to have power to control still, thus stronger QPSK interference can be formed to Target cell, because SAIC receiver is only better to GMSK co-channel interference inhibition, even if therefore in current net, the good SAIC terminal of performance also cannot eliminate the co-channel interference of QPSK effectively, thus affect the link-quality of Target cell co-frequency co-time slot user.According to research, although VAMOS technology can compatible existing non-SAIC terminal and SAIC terminal, after user's pairing, the performance loss produced when constant power distributes is about 6-9dB; Control according to power division and power, then the user performance loss that power division is less will be more serious, and link performance decline directly limit the lifting amplitude of VAMOS technology to gsm system voice capacity.And, in the region that frequency reuse is tighter, adopt VAMOS technology to some speech coding mode (such as HR (HalfRate; Half rate encoded)) decline of power system capacity can be caused on the contrary.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is described.
execution mode 1
Fig. 1 shows according to an embodiment of the invention for carrying out distribution method 1000 to the communication resource of the homogeneous-frequency adjacent-domain in VAMOS system.Well known, multiple adjacent area 1-19 can be comprised in VAMOS system, as shown in Figure 2.Multiple adjacent area 1-19 forms the homogeneous frequency adjacent adjacent area that many groups have same communication resource (such as having identical communication frequency and time slot), such as community 1 and community 8,9,10,11,12 and 13 form one group of homogeneous frequency adjacent area, and community 2 and community 4,6,15 and 17 form one group of homogeneous frequency adjacent adjacent area etc.Wherein, occur that user initially accesses, the community of the event such as timer triggering that user's pairing, user's separation of copulating moth and base station controller (BSC) are arranged for each community is described " Target cell ", other community belonged in same group of homogeneous frequency adjacent area with Target cell is referred to herein as " homogeneous-frequency adjacent-domain ".Such as, when community 1 is Target cell, community 8,9,10,11,12 and 13 is the homogeneous-frequency adjacent-domain of community 1.
As shown in Figure 1, in the step s 100, such as BSC receives the configuration-direct from control appliance (such as Network Management Equipment), then determines the preferred resources pond of the communication resource of Target cell and not preferred resource pool in step s 110.BSC according to the configuration-direct received semi-statically for matching user's configuration communication resource (comprising frequency and time interval resource) in Target cell and homogeneous-frequency adjacent-domain thereof, and using the communication resource that configures for Target cell as preferred resources pond.
Such as, suppose that the instruction of the control appliance that BSC receives in the step s 100 is as shown in table 1, Target cell (such as, community 1) take f1-6 (frequency)-TS0 (time slot) and f1-TS1, the homogeneous-frequency adjacent-domain 8 of Target cell 1 takies f2-6-TS1 and f1-3-TS2 etc.BSC semi-statically carries out communication resource configuration to the pairing user in community 1 and co-frequency cell 8-13 thereof according to the instruction received.

| Frequency 1 | Community 1 | Community 1 | Community 8 | Community 9 | Community 10 | Community 11 | Community 12 | Community 13 |

| Frequency 6 | Community 1 | Community 8 | Community 9 | Community 10 | Community 11 | Community 11 | Community 12 | Community 13 |
Table 1
As can be seen from Table 1, the resource non-overlapping copies configured.The communication resource that BSC is the semi-static configuration in Target cell according to instruction is preferred resources pond, and other communication resources outside preferred resources pond are not preferred resource pool.Can adjust according to each community actual conditions the communication resource of the semi-static configuration in Target cell and homogeneous-frequency adjacent-domain thereof, such as when number of users, the type change of Target cell and homogeneous-frequency adjacent-domain thereof, the communication resource can be reconfigured according to different instruction to each community.The resource distribution of which to each community is fairly simple, and the structure of corresponding BSC is also fairly simple, is particularly useful for the resource distribution of network initial stage each community.
Then, in S120, judge whether preferred resources pond exists the communication resource can distributing to Target cell.In one embodiment, if the communication resource is not all by the pairing CU in Target cell in above-mentioned preferred resources pond, then think that exist in preferred resources pond can allocate communications resource, if all communication resources are all by the pairing CU in Target cell in above-mentioned preferred resources pond, then thinking can not allocate communications resource in preferred resources pond.Such as, suppose that community 1 is for Target cell, the preferred resources pond determined for Target cell is in the step s 100 f1-TS0, f1-TS1, f2-TS0, f3-TS0, f4-TS0, f5-TS0 and f6-TS0, as shown in table 1; If the pairing CU in f2-TS0 and f5-TS0 Wei Bei community 1, then f2-TS0 and f5-TS0 is the allowable resource in preferred resources pond, if f4-TS0 is by the pairing CU of community 1, then the f4-TS0 in preferred resources pond does not belong to allowable resource.Be described for Target cell for community 1 below.
If the result judged is, namely, in the preferred resources pond of community 1 exist can allocate communications resource (such as, f2-TS0 and f5-TS0) time, then in step s 130, which according to the pairing user in Target cell priority higher than the priority of isolated user order by preferred resources pond can allocate communications Resourse Distribute to pairing user to be allocated in Target cell and/or isolated user.Such as, when needing the user of allocate communications resource to comprise pairing user 1-1,1-2 and isolated user 1-3 in community 1, preferentially such as f2-TS0 or f5-TS0 of the allowable resource in preferred resources pond is distributed to pairing user 1-1 and 1-2.
Whether if the result judged in the step s 120 is no, that is, when not having allowable resource in the preferred resources pond of community 1, then judging further in step s 130, which to exist in the not preferred resource pool of community 1 can allocate communications resource.Specifically, if the communication resource in the not preferred resource pool of community 1 is not taken by the pairing user of Target cell or isolated user, then think that this communication resource is the allowable resource in not preferred resource pool.Any CU in such as, f2-TS1 Wei Bei community 1 in not preferred resource pool, then think that f2-TS1 is the allowable resource in not preferred resource pool.But not the f3-TS3 in preferred resources pond is by the pairing CU in community 1, then think that f3-TS3 does not belong to the allowable resource in not preferred resource pool.
If the result judged in step s 130, which is without allowable resource in non-preferred resources pond, then do not carry out Resourse Distribute to the pairing user in Target cell and/or isolated user, namely method 1000 terminates; Otherwise, in S150, discharge the communication resource matched shared by user or isolated user in preferred resources pond.
Fig. 3 illustrate in detail the further process of step S150.As shown in Figure 3, in S151, judge the user type (i.e. the user type of the communication resource to be allocated) of request dispatching resource in Target cell 1.If the user of request dispatching resource is isolated user, then in the pairing user selecting preferred resources pond corresponding in S152 or isolated user, speech coding mode is compared with robust and the low isolated user of power requirement.Then in step S153 by speech coding mode in pairing user corresponding for preferred resources pond or isolated user compared with robust and the low isolated user of power requirement be distributed on the allowable resource in not preferred resource pool, thus discharge the communication resource in preferred resources pond.Suppose the f2-TS0 in preferred resources pond, f5-TS0, f6-TS0 is respectively by the pairing user 1-4 of community 1, 1-5 and isolated user 1-6, isolated user 1-7 takies, and match user 1-4 and 1-5 and isolated user 1-6 and adopt AMR-FR speech coding, and isolated user 1-7 adopts FR speech coding, suppose that the reliability order from high to low of speech coding mode is AMR-FR > EFR > AMR-HR ≈ FR > HR, then from pairing user corresponding to preferred resources pond or isolated user, select isolated user 1-6.In step S153, f2-TS1 as escribed above for the allowable resource in not preferred resource pool is distributed to isolated user 1-6, thus isolated user discharges the communication resource f5-TS0 in preferred resources pond, then the communication resource f5-TS0 that isolated user 1-6 discharges is distributed to isolated user 1-3 to be allocated in community 1.If now there is the isolated user 1-6 ' taking f3-TS0 in preferred resources pond, and also adopt AMR-FR speech coding, but be in the edge of community, place, and isolated user 1-6 is in the center of community, place, then prioritizing selection isolated user 1-6.Because not only speech coding mode reliability is high for isolated user 1-6, and be in the center of community 1, the interference produced community 1 is the GMSK interference that SAIC terminal is easy to eliminate, therefore select user 1-6 can promote the link-quality of homogeneous-frequency adjacent-domain pairing user, and then promote VAMOS power system capacity.
If the result judged in step S151 is the user of request dispatching resource as pairing user, then in step S154, judge whether to exist in the pairing user that preferred resources pond is corresponding or isolated user speech coding mode compared with robust and the low isolated user of power requirement.If had, in step S153, this isolated user is assigned on the allowable resource in not preferred resource pool, thus discharges the preferred resources that this isolated user takies.Such as, isolated user 1-6 is selected the pairing user corresponding from preferred resources pond or isolated user, f2-TS1 as escribed above for allowable resource in not preferred resource pool is distributed to isolated user 1-6, thus isolated user 1-6 discharges the communication resource f5-TS0 in preferred resources pond, then the communication resource f5-TS0 that isolated user 1-6 discharges is distributed to pairing user 1-1 and 1-2 to be allocated in community 1.
If the result judged in step S154 is no, then in the pairing user selecting preferred resources pond corresponding in step S155 or isolated user, speech coding mode is compared with robust and the low pairing user of power requirement.Then in step S180, this pairing user is assigned on the allowable resource in not preferred resource pool, thus discharges the preferred resources of this pairing CU.Such as, pairing user 1-4 and 1-5 of above-mentioned employing AMR-FR speech coding can be selected, pairing user 1-4 and 1-5 will can be given by allocate communications Resourse Distribute in not preferred resource pool, thus the communication resource f2-TS0 discharged in preferred resources pond, discharged communication resource f2-TS0 is distributed to pairing user 1-1 and 1-2 in Target cell.
By this embodiment, Target cell and homogeneous-frequency adjacent-domain pairing CU the communication resource on avoid distributing user as far as possible, and on the frequency as far as possible the pairing user of Target cell being distributed in isolated user place, homogeneous-frequency adjacent-domain and time interval resource, thus reduce the intensity of co-channel interference suffered by VAMOS pairing user, and avoid the pairing user of homogeneous-frequency adjacent-domain QPSK signal to Target cell and the interference of isolated user, promote the link performance of pairing user; On the communication resource at pairing user place, homogeneous-frequency adjacent-domain during necessary distributing user, then select the high speech coding mode of reliability and the low isolated user of power requirement, thus make homogeneous-frequency adjacent-domain QPSK signal reduce to minimum to the pairing user of Target cell and the interference of isolated user, thus the link performance of user in raising network, capacity.
execution mode 2:
Figure 4 shows that the method 2000 in accordance with another embodiment of the present invention for distributing the communication resource of the homogeneous-frequency adjacent-domain in VAMOS system.Method 2000 initially accesses Target cell, user at Target cell pairing and the event such as separation of copulating moth or base station controller (BSC) for the timer triggering etc. that each community is arranged starts to perform based on user.
As shown in the figure, in step S210, the preferred resources pond of the communication resource that will distribute for Target cell and not preferred resource pool is determined.In this embodiment, BSC according to the communication resource information of the pairing CU in the corresponding relation Real-time Obtaining Target cell of Target cell and its homogeneous-frequency adjacent-domain and homogeneous-frequency adjacent-domain thereof, thus determines preferred resources pond and not preferred resource pool.Configurable first mapping table as shown in table 2 in BSC, also anyly can be obtained the first relation table by the equipment of BSC obtaining information from other, the first mapping table at least comprises the corresponding relation of Target cell and its homogeneous-frequency adjacent-domain.The number of plies of the homogeneous-frequency adjacent-domain of configuration depends on that the number of plies of the homogeneous-frequency adjacent-domain of collaborative Resourse Distribute is carried out in needs and Target cell.Generally speaking, the interference strength produced due to ground floor homogeneous-frequency adjacent-domain is maximum, and considers the disposal ability of BSC, therefore configures ground floor homogeneous-frequency adjacent-domain.As shown in table 2, for community 1 as Target cell, then in the first relation table, at least comprise its ground floor co-frequency cell, i.e. community 9, community 10, community 11, community 12, community 13.
| Target cell | Ground floor homogeneous-frequency adjacent-domain | N-th layer homogeneous-frequency adjacent-domain |
| Community 1 | Community 8, community 9, community 10, community 11, community 12, community 13 | ... |
| Community 2 | Community 4, community 6, community 15, community 17... | ... |
| Community 3 | Community 5, community 7, community 14, community 16... | ... |
| ... | ... | ... |
Table 2
The communication resource information of BSC Real-time Obtaining comprises in homogeneous-frequency adjacent-domain the frequency of CU and the time interval resource information of matching, such as, match CU f1-TS0 in community 1, match CU f1-TS2, f3-TS2, f6-TS2 in community 8, in community 9, match the communication resource distribution information such as CU f4-TS3.Then the not preferred resource pool of Target cell is defined as, unless the communication resource outside preferred resources pond is defined as preferred resources pond by matching the communication resource shared by user in Target cell and homogeneous-frequency adjacent-domain thereof.Such as f1-TS0, f1-TS2, f3-TS2, f6-TS2, f4-TS3 etc. all belong to not preferred resource pool.Obtain communication resource distribution information in the preferred resources pond of the Target cell determined and not preferred resource pool and be stored in BSC and can obtain on any equipment of its information, also can such as be stored in BSC with the form of table 3.
The communication resource corresponding to space in table 3 represents the communication resource in the preferred resources pond of Target cell, comprises the communication resource that taken by isolated user in Target cell and homogeneous-frequency adjacent-domain thereof and not by the communication resource of CU any in Target cell and homogeneous-frequency adjacent-domain thereof.Suppose that community 1 is for Target cell, the isolated user of community 9 occupies f2-TS2, the isolated user of community 11 occupies f4-TS4 and all vacant f6-TS6 of each community user, then f2-TS2, f4-TS4, f6-TS6 all belong to preferred resources pond.BSC initially can access based on user, user's pairing, user's separation of copulating moth and BSC are that the event his-and-hers watches 3 such as the timer triggering that arranges of Target cell upgrade.

Table 3-2
After second mapping table completes renewal, then determine not preferred resource pool and preferred resources pond.
Then, above-mentioned steps S220 ~ S150 is carried out.For clarity sake, concrete example is provided below.
For community 1 for Target cell, with reference to table 3, in S220, judge whether preferred resources pond exists the assignable communication resource in Target cell.Suppose any CU in f2-TS0 and f5-TS0 Wei Bei community 1, then f2-TS0 and f5-TS0 is the allowable resource in preferred resources pond, and f4-TS0 is by the pairing CU of community 1, then the f4-TS0 in preferred resources pond does not belong to allowable resource.When in preferred resources pond exist can allocate communications resource time, if the user of the communication resource to be allocated comprises pairing user 1-1,1-2 and isolated user 1-3 in community 1, then in step S230, preferentially such as f2-TS0 or f5-TS0 of the allowable resource in preferred resources pond is distributed to pairing user 1-1,1-2.
Whether when not having allowable resource in the preferred resources pond judging community 1 in S220, then perform step S240, judging further to exist in the not preferred resource pool of community 1 in step S240 can allocate communications resource.Any CU in such as, f2-TS4 Wei Bei community 1 in not preferred resource pool, then think that f2-TS4 is the allowable resource in not preferred resource pool.But not the f3-TS2 in preferred resources pond is by the pairing CU in community 1, then think that f3-TS2 does not belong to the allowable resource in not preferred resource pool.If the judged result in step S240 is no, the pairing user in Ze Budui community 1 and/or isolated user carry out Resourse Distribute.
If judged result is yes in step S240, then discharge the communication resource matched shared by user or isolated user in preferred resources pond in step s 250.The process of step S250 is identical with the first execution mode shown in Fig. 3, therefore repeats no more.
Described above is the method for being Target cell allocate communications resource in VAMOS system according to the application aspect.Describe according to the application's resource allocation device embodiment for VAMOS system on the other hand below with reference to Fig. 5.

Resource pool determination module 301 determines the preferred resources pond of the communication resource of Target cell and not preferred resource pool, and the communication resource such as can comprise communication frequency and time slot.In one embodiment, resource pool determination module 301 determines the preferred resources pond of the communication resource of Target cell and not preferred resource pool according to the mode of semi-static configuration, such as, be that pairing user in described Target cell and homogeneous-frequency adjacent-domain thereof configures the described communication resource according to control command, and the communication resource for the configuration of described Target cell is defined as described preferred resources pond, wherein, for matching user configured communication resource non-overlapping copies in described Target cell and homogeneous-frequency adjacent-domain thereof.The mode of semi-static configuration is identical with above-mentioned steps S100, therefore repeats no more.Another execution mode in, the communication resource information of the pairing CU in resource pool determination module 301 Target cell and homogeneous-frequency adjacent-domain thereof according to the corresponding relation Real-time Obtaining of Target cell and its homogeneous-frequency adjacent-domain, and the communication resource matched in Target cell and homogeneous-frequency adjacent-domain thereof outside the communication resource shared by user is defined as preferred resources pond.In other words, the mode determination preferred resources pond of Real-time Obtaining resource information and not preferred resource pool is utilized.Concrete treatment step is with identical to the description of step S100 in execution mode 2.
When Target cell and its homogeneous-frequency adjacent-domain cover at least two BSC, resource pool determination module 301 is based on event or the periodic assignment information of the communication resource in the preferred resources pond of Target cell described in Trigger update and not preferred resource pool.Described event comprises that user in Target cell initially accesses, user's pairing and user's separation of copulating moth, and the timer triggering arranged for Target cell.
Judge module 302, judges whether determined preferred resources pond exists the assignable communication resource in above-mentioned Target cell, namely whether there is utilizable communication frequency and time slot.
When the result that judge module 302 judges is as being, resource distribution module 303 will can give pairing user to be allocated and/or isolated user in described Target cell by allocate communications Resourse Distribute in preferred resources pond according to the priority of the pairing user in described Target cell higher than the order of the priority of isolated user.
If when the result that described judge module 302 judges in above-mentioned judgement process is no, judge module 302 also determines whether there is the assignable communication resource in the not preferred resource pool of described Target cell further; If existed, the pairing user that the above-mentioned preferred resources pond determined by resource pool determination module 301 of resource distribution module 303 is corresponding or isolated user are assigned on the allowable resource in the not preferred resource pool that resource pool determination module 301 determines, to discharge this pairing user or the communication resource shared in described preferred resources pond of isolated user.In one embodiment, resource distribution module 303 is prioritizing selection speech coding mode comparatively robust and the low isolated user of power requirement in pairing user corresponding to the preferred resources pond of Target cell or isolated user, and be assigned on the allowable resource in not preferred resource pool by selected isolated user, thus discharge this isolated user communication resource shared in described preferred resources pond.Select as one, resource distribution module 303 selects speech coding mode robust and the low pairing user of power requirement in pairing user corresponding to the preferred resources pond of Target cell or isolated user; And selected pairing user be assigned on the allowable resource in not preferred resource pool, thus discharge the preferred resources of this pairing CU.
The foregoing is only embodiments of the invention, be not intended to limit protection scope of the present invention, but for illustration of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
