The VAMOS system comprises at least one target cell and each same-frequency neighbor cell corresponding to the target cell. The method comprises the following steps of: determining a preferable resource pool and a non-preferable resource pool of communication resources for the target cell; judging that the preferable resource pool comprises the communication resources allocable to the target cell; and sequentially allocating the communication resources to matched users with higher priorities and independent users with lower priorities in the target cell.
Description
Technical field
The present invention relates to the communications field, relate in particular to homogeneous-frequency adjacent-domain allocation of communication resources method in a kind of VAMOS system and be used for the resource allocation device 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 voice user of GSM network is adopted the notion of the same time slot of the multiplexing same frequency of a plurality of users, be about to a plurality of user's voice information multiplexings and on a time slot, launch transmission, terminal and base station receiver are respectively by elimination pairing user's the interference and the method demodulation target information of joint-detection, thus the voice capacity of raising GSM network.Particularly, in the VAMOS system, use QPSK (Quadrature Phase Shift Keying on the network side down direction; Quarternary phase-shift keying (QPSK)) modulation system is modulated to two pairing user's voice data respectively on the I road and Q road of quadrature, and by give the pairing user distribute orthogonality preferably TSC (training sequence code) sequence make terminal can distinguish the user of pairing with it, demodulate desired data.On up direction, the pairing user still adopts GMSK (Gaussian Minimum Shift Keying; Gaussian-filtered minimum shift keying) modulation system is distinguished by the TSC sequence of quadrature, and data are sent on same time slot, and base station side is distinguished the user with TSC, and carries out demodulation by joint-detection.
At present, the 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 disturb frequently), wherein the interference strength that produces with the co-channel interference signal of ground floor homogeneous-frequency adjacent-domain again is the strongest.Disturb in order to eliminate as far as possible effectively, big multiple mobile phone terminals adopts SAIC (Single Antenna Interference Cancellation; The single antenna interference eliminated) algorithm plays the co-channel interference signal under the GMSK modulation mode and to suppress effect preferably.Yet, in current VAMOS system, pairing user repeatedly using same time slot, the user that then matches has constituted very strong co-channel interference mutually, increase existing terminal and eliminated the difficulty of co-channel interference, thereby the user's receptivity that causes matching significantly descends, particularly, the time slot at the VAMOS pairing user place in the homogeneous-frequency adjacent-domain is owing to provide power for two users simultaneously, though power control is arranged but generally the power magnitude than isolated user is big for the gross power amplitude, thereby can form stronger QPSK to Target cell disturbs, because it is better that the SAIC receiver only suppresses effect to the GMSK co-channel interference, even therefore in the current net performance preferably the SAIC terminal also can't eliminate the co-channel interference of QPSK effectively, thereby influence Target cell co-frequency co-time slot user's link-quality.According to research, though the VAMOS technology can compatible existing non-SAIC terminal and SAIC terminal, after user's pairing, the about 6-9dB of performance loss that under the situation that constant power distributes, produces; If adopt the control of power division and power, then the less user performance loss of power division will be more serious, and link performance decline has directly limited the lifting amplitude of VAMOS technology to the gsm system voice capacity.And, in the tighter zone of frequency reuse, adopt the VAMOS technology to some speech coding pattern (HR (HalfRate for example; Half rate encoded)) can cause the decline of power system capacity on the contrary.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is described.
Fig. 1 shows the communication resource that is used for according to an embodiment of the invention the homogeneous-frequency adjacent-domain of VAMOS system and carries out distribution method 1000.Known ground can comprise a plurality of adjacent area 1-19, as shown in Figure 2 in the VAMOS system.A plurality of adjacent area 1-19 constitute the homogeneous frequency adjacent adjacent area that many groups have same communication resource (for example having identical communication frequency and time slot), for example sub-district 1 and sub-district 8,9,10,11,12 and 13 constitute one group of homogeneous frequency adjacent area, and sub-district 2 and sub-district 4,6,15 and 17 constitute one group of homogeneous frequency adjacent adjacent area etc.Wherein, take place that the user initially inserts, user's pairing, user's separation of copulating moth and base station controller (BSC) be described " Target cell " for the sub-district of the incidents such as timer triggering of each sub-district setting, other sub-district that belongs in the same group of homogeneous frequency adjacent area with Target cell is referred to herein as " homogeneous-frequency adjacent-domain ".For example, when sub-district 1 was Target cell, sub-district 8,9,10,11,12 and 13 was the homogeneous-frequency adjacent-domain of sub-district 1.
As shown in Figure 1, in step S100, for example BSC receives the configuration-direct from control appliance (for example Network Management Equipment), then determines the preferred resources pond and the not preferred resource pool of the communication resource of Target cell in step S110.BSC is pairing user's configuration communication resource (comprising frequency and time interval resource) in Target cell and the homogeneous-frequency adjacent-domain thereof according to the configuration-direct that receives semi-staticly, and will for the communication resource of Target cell configuration as the preferred resources pond.
For example, suppose that the instruction of the control appliance that BSC receives is as shown in table 1 in step S100, Target cell (for example, sub-district 1) takies f1-6 (frequency)-TS0 (time slot) and f1-TS1, and the homogeneous-frequency adjacent-domain 8 of Target cell 1 takies f2-6-TS1 and f1-3-TS2 etc.BSC communicates resource distribution to the pairing user among sub-district 1 and the co-frequency cell 8-13 thereof according to the instruction that receives semi-staticly.

Table 1
From table 1, can find out the resource non-overlapping copies that is disposed.BSC is the preferred resources pond according to instruction for the communication resource of the semi-static configuration of Target cell, and other communication resources outside the preferred resources pond are not preferred resource pool.The communication resource to Target cell and the semi-static configuration of homogeneous-frequency adjacent-domain thereof can be adjusted according to each sub-district actual conditions, for example when the number of users of Target cell and homogeneous-frequency adjacent-domain thereof, type change, can reconfigure the communication resource to each sub-district according to different instruction.This mode is fairly simple to the resource distribution of each sub-district, and the structure of corresponding BSC is also fairly simple, is particularly useful for the resource distribution of each sub-district of network initial stage.
Then, judge in S120 whether the preferred resources pond exists the communication resource that can distribute to Target cell.In one embodiment, if the communication resource is not all by the pairing CU in the Target cell in the above-mentioned preferred resources pond, but then think and have the allocate communications resource in the preferred resources pond, if all communication resources are all by the pairing CU in the Target cell in the above-mentioned preferred resources pond, but then think and do not have the allocate communications resource in the preferred resources pond.For example, suppose that sub-district 1 is Target cell, the preferred resources pond of determining for Target cell in step S100 is f1-TS0, f1-TS1, f2-TS0, f3-TS0, f4-TS0, f5-TS0 and f6-TS0, and is as shown in table 1; If f2-TS0 and f5-TS0 be not by the pairing CU in the sub-district 1, then f2-TS0 and f5-TS0 are the allowable resource in the preferred resources pond, if f4-TS0 is by the pairing CU of sub-district 1, then the f4-TS0 in the preferred resources pond does not belong to allowable resource.Be that Target cell is that example is described with sub-district 1 below.
If the result who judges is, promptly, but (for example there is the allocate communications resource in the preferred resources pond of sub-district 1, f2-TS0 and f5-TS0) time, but the order that then is higher than the priority of isolated user according to the priority of the pairing user in the Target cell in step S130 is given pairing user and/or isolated user to be allocated in the Target cell with the allocate communications resource allocation in the preferred resources pond.For example, when the user who needs the allocate communications resource in sub-district 1 comprised pairing user 1-1,1-2 and isolated user 1-3, preferentially for example f2-TS0 or f5-TS0 distributed to pairing user 1-1 and 1-2 with the allowable resource in the preferred resources pond.
If the result who judges is not for, that is, when not having allowable resource in the preferred resources pond of sub-district 1, but then in step S130, further judge in the not preferred resource pool of sub-district 1 whether have the allocate communications resource in step S120.Particularly, if the communication resource in the not preferred resource pool of sub-district 1 is not taken by the pairing user or the isolated user of Target cell, think that then this communication resource is the allowable resource in the not preferred resource pool.F2-TS1 in for example not preferred resource pool is not taken by the Any user in the sub-district 1, thinks that then f2-TS1 is the allowable resource in the not preferred resource pool.But not the f3-TS3 in the preferred resources pond thinks then that by the pairing CU in the sub-district 1 f3-TS3 does not belong to the allowable resource in the not preferred resource pool.
If the result who judges in step S130 does not have allowable resource in the non-preferred resources pond, then pairing user in the Target cell and/or isolated user are not carried out resource allocation, promptly method 1000 finishes; Otherwise, in S150, discharge the pairing user or the shared communication resource of isolated user in the preferred resources pond.
Fig. 3 at length shows the further processing of step S150.As shown in Figure 3, in S151, judge the user type (being the user type of the communication resource to be allocated) of request Resources allocation in the Target cell 1.If the user of request Resources allocation be an isolated user, then in S152 in the pairing user of selection preferred resources pond correspondence or the isolated user speech coding pattern than robust and the low isolated user of power requirement.Then in step S153, speech coding pattern in the pairing user of preferred resources pond correspondence or the isolated user is distributed on the allowable resource in the not preferred resource pool than robust and the low isolated user of power requirement, thereby discharges the communication resource in the preferred resources pond.Suppose that f2-TS0, f5-TS0, f6-TS0 in the preferred resources pond are taken by pairing user 1-4, the 1-5 of sub-district 1 and isolated user 1-6, isolated user 1-7 respectively, and pairing user 1-4 and 1-5 and isolated user 1-6 adopt the AMR-FR speech coding, and isolated user 1-7 adopts the FR speech coding, the reliability order from high to low of supposing the speech coding pattern is AMR-FR＞EFR＞AMR-HR ≈ FR＞HR, then selects isolated user 1-6 from the pairing user of preferred resources pond correspondence or isolated user.F2-TS1 in step S153 that the allowable resource in the not preferred resource pool is for example above-mentioned distributes to isolated user 1-6, thereby isolated user discharges the communication resource f5-TS0 in the preferred resources pond, and the communication resource f5-TS0 that isolated user 1-6 is discharged distributes to isolated user 1-3 to be allocated in the sub-district 1 then.Take the isolated user 1-6 ' of f3-TS0 if exist in the preferred resources pond this moment, and also adopt the AMR-FR speech coding, but be in the edge of sub-district, place, and isolated user 1-6 is in the center of sub-district, place, then preferentially selects isolated user 1-6.Because isolated user 1-6 is speech coding pattern reliability height not only, and be in the center of sub-district 1, the interference that sub-district 1 produces is disturbed for the GMSK that the SAIC terminal is easy to eliminate, therefore select user 1-6 can promote homogeneous-frequency adjacent-domain pairing user's link-quality, and then promote the VAMOS power system capacity.
Be the pairing user if the result who judges is the user of request Resources allocation in step S151, then in step S154, judge in the pairing user of preferred resources pond correspondence or the isolated user whether exist the speech coding pattern than robust and the low isolated user of power requirement.If have, in step S153, this isolated user is assigned on the allowable resource in the not preferred resource pool, thereby discharges the preferred resources that this isolated user takies.For example, from the pairing user of preferred resources pond correspondence or isolated user, select isolated user 1-6, the f2-TS1 that allowable resource in the not preferred resource pool is for example above-mentioned distributes to isolated user 1-6, thereby isolated user 1-6 discharges the communication resource f5-TS0 in the preferred resources pond, and the communication resource f5-TS0 that isolated user 1-6 is discharged distributes to pairing user 1-1 and 1-2 to be allocated in the sub-district 1 then.
If the result who judges in step S154 for not, then selects in the pairing user of preferred resources pond correspondence or the isolated user speech coding pattern than robust and the low pairing user of power requirement in step S155.Then in step S180, this pairing user is assigned on the allowable resource in the not preferred resource pool, thereby discharges the preferred resources of this pairing CU.For example, can select the pairing user 1-4 and the 1-5 of above-mentioned employing AMR-FR speech coding, but give pairing user 1-4 and 1-5 with the allocate communications resource allocation in the not preferred resource pool, thereby discharge the communication resource f2-TS0 in the preferred resources pond, the communication resource f2-TS0 that is discharged is distributed to pairing user 1-1 and 1-2 in the Target cell.
By this embodiment, on the communication resource of Target cell and homogeneous-frequency adjacent-domain pairing CU thereof, avoid distributing user as far as possible, and the pairing user with Target cell is distributed on the frequency and time interval resource at homogeneous-frequency adjacent-domain isolated user place as far as possible, thereby reduce the intensity of the suffered co-channel interference of VAMOS pairing user, and avoid homogeneous-frequency adjacent-domain QPSK signal to the pairing user of Target cell and the interference of isolated user, promote pairing user's link performance; In the time of must distributing user on the communication resource at homogeneous-frequency adjacent-domain pairing user place, then select high speech coding pattern of reliability and the low isolated user of power requirement, thereby make homogeneous-frequency adjacent-domain QPSK signal reduce to minimum to the pairing user of Target cell and the interference of isolated user, thereby user's link performance in the raising network, the elevator system capacity.
Execution mode 2:
Figure 4 shows that and be used for the method 2000 that the communication resource to the homogeneous-frequency adjacent-domain of VAMOS system distributes in accordance with another embodiment of the present invention.Method 2000 initially inserts timer triggering that Target cell, user be provided with for each sub-district at incident such as Target cell pairing and separation of copulating moth or base station controller (BSC) etc. based on the user and begins execution.
As shown in the figure, in step S210, determine the preferred resources pond and the not preferred resource pool of the communication resource that will distribute for Target cell.In this embodiment, BSC obtains the communication resource information of the pairing CU in Target cell and the homogeneous-frequency adjacent-domain thereof in real time according to the corresponding relation of Target cell and its homogeneous-frequency adjacent-domain, thereby determines preferred resources pond and not preferred resource pool.Configurable first mapping table as shown in table 2 among the BSC also can anyly can be obtained first relation table by the equipment that BSC obtains information from other, and first mapping table comprises the corresponding relation of Target cell and its homogeneous-frequency adjacent-domain at least.The number of plies of homogeneous-frequency adjacent-domain of configuration depends on that needs and Target cell work in coordination with the number of plies of the homogeneous-frequency adjacent-domain of resource allocation.Generally speaking, because the interference strength maximum that the ground floor homogeneous-frequency adjacent-domain produces, and the disposal ability of consideration BSC, therefore dispose the ground floor homogeneous-frequency adjacent-domain and get final product.As shown in table 2, be example with sub-district 1 as Target cell, then in first relation table, comprise its ground floor co-frequency cell at least, i.e. sub-district 9, sub-district 10, sub-district 11, sub-district 12, sub-district 13.

Table 2
The communication resource information that BSC obtains in real time comprises the frequency and the time interval resource information of pairing CU in the homogeneous-frequency adjacent-domain, for example in the sub-district 1 pairing CU f1-TS0, in the sub-district 8 pairing CU f1-TS2, f3-TS2, f6-TS2, in the sub-district 9 pairing CU communication resource distribution information such as f4-TS3.Then the shared communication resource of pairing user in Target cell and the homogeneous-frequency adjacent-domain thereof is defined as the not preferred resource pool of Target cell, unless the communication resource outside the preferred resources pond is defined as the preferred resources pond.For example f1-TS0, f1-TS2, f3-TS2, f6-TS2, f4-TS3 etc. all belong to not preferred resource pool.Communication resource distribution information is stored in BSC and can obtains on any equipment of its information in the preferred resources pond of definite Target cell that obtains and the not preferred resource pool, also can be for example be stored among the BSC with the form of table 3.
The pairing communication resource in space in the table 3 is represented the communication resource in the preferred resources pond of Target cell, comprises the communication resource that is taken by isolated user in Target cell and the homogeneous-frequency adjacent-domain thereof and the communication resource that is not taken by Any user in Target cell and the homogeneous-frequency adjacent-domain thereof.Suppose that sub-district 1 is Target cell, the isolated user that the isolated user of sub-district 9 has taken f2-TS2, sub-district 11 has taken f4-TS4 and all vacant f6-TS6 of each community user, and then f2-TS2, f4-TS4, f6-TS6 all belong to the preferred resources pond.The incident his-and-hers watches 3 such as timer triggering that BSC can initially insert based on the user, user pairing, user's separation of copulating moth and BSC are the Target cell setting upgrade.

Table 3
When Target cell and at least two BSC of homogeneous-frequency adjacent-domain covering thereof, also comprise sub-district ownership BSC information as shown in table 4 in then above-mentioned first mapping table 2.
Table 4
As shown in table 4, sub-district 1 and homogeneous-frequency adjacent-domain sub-district 8 thereof, sub-district 9, sub-district 10 and sub-district 11 belong to BSC1, and sub-district 12 belongs to BSC2, and sub-district 13 belongs to BSC3.Like this, when BSC1 is based on incident or periodic triggering renewal second mapping table (seeing Table 3) in above-mentioned second execution mode, for example, suppose that sub-district 1 is Target cell, then BSC1 is source BSC, BSC1 is according to the ownership BSC information in first mapping table, obtain the communication resource information that BSC1 internal object sub-district and its homogeneous-frequency adjacent-domain pairing user distributes, promptly obtain the communication resource information of in the sub-district 1,8,9,10,11 user being distributed, belong to the communication resource information of each sub-district of BSC1 then in the updating form 3.For example table 3 is updated to table 3-1, as show shown in the 3-1, the shared resource information of pairing user is upgraded in the sub-district 1,8,9,10,11, because sub-district 12,13 belongs to BSC2, BSC3 respectively, so the shared resource information of pairing user is not upgraded in the sub-district 12,13 of storing among the BSC1 this moment.

Table 3-1
Simultaneously, the different B SC of BSC1 under homogeneous-frequency adjacent-domain is that purpose BSC sends a request message, for example send a request message to the BSC2 of sub-district 12 ownership and the BSC3 of sub-district 13 ownership, this request message comprises type of message, source BSC ID (for example, the ID of BSC1), purpose BSC ID (for example ID of the ID of BSC2 and BSC3) and Target cell ID (for example ID of sub-district 1) at least.Request message arrives MSC (Mobile Switch Center through the A interface; Mobile switching centre), MSC reads the ID of BSC2 and the ID of BSC3, then this request message is passed through BSC2 and BSC3.BSC2 and BSC3 receive that the communication resource information of obtaining BSC1 behind the request message promptly shows the information among the 3-1, and return response message to BSC1.This response message comprises has at least distributed to pairing user's communications resource information among type of message, source BSC ID, purpose BSC ID, Target cell ID and BSC2 and the BSC3.
BSC1 reads this response message and finishes renewal to second mapping table according to this response message.For example represent in the response message that BSC2 returns that this moment, sub-district 12 took f4-TS6, and expression sub-district 13 takies f4-TS7 at this moment in the response message that BSC3 returns, then BSC1 will show 3-1 according to the response message of receiving and be updated to table 3-2, thereby finish the renewal to second mapping table.

Table 3-2
After second mapping table is finished renewal, not preferred resource pool and preferred resources pond have then been determined.
Then, carry out above-mentioned steps S220～S150.For clarity sake, provide concrete example below.
With sub-district 1 is that Target cell is an example, with reference to table 3, judges in S220 whether the preferred resources pond exists the assignable communication resource in Target cell.Suppose that f2-TS0 and f5-TS0 are not taken by the Any user in the sub-district 1, then f2-TS0 and f5-TS0 are the allowable resource in the preferred resources pond, and f4-TS0 is by the pairing CU of sub-district 1, and then the f4-TS0 in the preferred resources pond does not belong to allowable resource.But when having the allocate communications resource in the preferred resources pond, if the user of the communication resource to be allocated comprises pairing user 1-1,1-2 and isolated user 1-3 in the sub-district 1, then preferentially for example f2-TS0 or f5-TS0 distribute to pairing user 1-1,1-2 with the allowable resource in the preferred resources pond in step S230.
When not having allowable resource in the preferred resources pond of in S220, judging sub-district 1, execution in step S240 then, but in step S240, further judge in the not preferred resource pool of sub-district 1 whether have the allocate communications resource.F2-TS4 in for example not preferred resource pool is not taken by the Any user in the sub-district 1, thinks that then f2-TS4 is the allowable resource in the not preferred resource pool.But not the f3-TS2 in the preferred resources pond thinks then that by the pairing CU in the sub-district 1 f3-TS2 does not belong to the allowable resource in the not preferred resource pool.If the judged result in step S240 is not then carried out resource allocation to pairing user in the sub-district 1 and/or isolated user for not.
If judged result is for being in step S240, then in step S250, discharge the pairing user or the shared communication resource of isolated user in the preferred resources pond.The processing of step S250 is identical with first execution mode shown in Fig. 3, therefore repeats no more.
