Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
In different systems, the title of terminal, base station control device and base station may be different, for example, in gsm system, terminal be travelling carriage (Mobile Station, MS), the base station is base transceiver station (Base Transceiver Station, BTS), base station control device be base station controller (Base Station Controller, BSC); At Wideband Code Division Multiple Access (WCDMA) (Wideband CodeDivision Multiple Access, WCDMA) and TD SDMA (Time DivisionSynchronous Code Division Multiple Access, TD-SCDMA) in the system, terminal is subscriber equipment (User Equipment, UE), the base station is NodeB, base station control device be radio network controller (Radio Network Controller, RNC); Long Term Evolution (Long TermEvolution, LTE) in the system, terminal is UE, the base station is evolution base station (eNodeB), base station control device be gateway (Servicing Gateway, SGW) and mobile management entity (MobileManagement Entity, MME).
Following embodiment is an example with the gsm system, is understandable that, following embodiment also can be applied in other the system.
Fig. 1 is the schematic flow sheet of the collaboration communication method of first embodiment of the invention, comprising:
Step 11: the judged result that the equipment of the measurement report that reports according to MS or the Serving cell of terminal sends determines whether this MS is in covering overlapping area and comprises the adjacent sub-district of this covering overlapping area, wherein this judged result judged result of whether this MS being in covering overlapping area and comprising the adjacent sub-district of this covering overlapping area for the measurement report that reports according to MS.
Can determine according to the descending incoming level of Serving cell and the descending incoming level of adjacent sub-district in the measurement report of MS transmission whether this MS is positioned at covering overlapping area by BSC herein.
Also can be, the equipment of Serving cell obtains the judged result whether MS is positioned at covering overlapping area according to the descending level of the gentle adjacent sub-district of downlink electrical of Serving cell in the measurement report of MS transmission, afterwards, the equipment by Serving cell sends to BTS with judged result.
In addition, the descending incoming level of the descending incoming level of Serving cell and adjacent sub-district determines to comprise the adjacent sub-district of this covering overlapping area in the measurement report that can be sent according to MS by BSC;
Also can be, the descending incoming level of the descending incoming level of Serving cell and adjacent sub-district determines to comprise the adjacent sub-district of this covering overlapping area in the measurement report that the equipment of Serving cell sends according to MS, afterwards, the information (as sub-district ID) that will comprise the adjacent sub-district of this covering overlapping area by the equipment of Serving cell sends to BSC as judged result.
Step 12: if this MS is in covering overlapping area, Serving cell to this MS sends the indication of cooperating with the adjacent sub-district (promptly can carry out the sub-district of collaboration communication with this MS) that comprises this covering overlapping area, make the equipment of this adjacent sub-district that comprises covering overlapping area will send to the equipment of this Serving cell from first upward signal that this MS receives by this cooperation indication, the equipment that makes this Serving cell merges processing with this first upward signal and second upward signal that receives from this MS.
Wherein, the adjacent sub-district that comprises covering overlapping area also can be determined according to the descending incoming level in the measurement report, for example, when the descending incoming level of the descending incoming level of a certain adjacent sub-district and Serving cell satisfies concerning of setting in advance, then should the neighbour sub-district be defined as comprising the adjacent sub-district of covering overlapping area.
Wherein, first upward signal and second upward signal include the relevant information of MS, Serving cell equipment can be defined as first upward signal and second upward signal of MS correspondence according to this relevant information, afterwards first upward signal and second upward signal is merged processing.With the gsm system is example, and different MS will send signal in different channels, can carry the channel number of this MS in this cooperation indication, and adjacent cell equipment and Serving cell equipment can carry out required processing according to channel number.
This cooperation indication can also can be carried in the existing signaling for newly-increased independent signaling, for example, is carried in the signal activation message.
In addition, the executive agent of present embodiment can be BSC, is judged according to the measurement report that MS reports by BSC.Be understandable that, also can judge according to this measurement report, afterwards,, issue the cooperation indication by BSC with judged result information notice BSC by BTS.
Need to prove, the terminal in the present embodiment can be called the terminal that is in the collaboration communication state.
First upward signal that present embodiment will obtain from adjacent cell equipment by Serving cell equipment and second upward signal that directly receives from terminal merge processing, can promote the upward signal quality of reception, improve speech business quality and data service throughput.
Fig. 2 is the schematic flow sheet of the collaboration communication method of second embodiment of the invention, comprising:
Step 21:BSC receives the descending level measurement report that MS sends, and carries the descending incoming level of Serving cell of corresponding MS and the adjacent cell downlink incoming level of this MS in this descending level measurement report.
Fig. 3 covers overlapping schematic diagram for sub-district in the second embodiment of the invention, and referring to Fig. 3, there are covering overlapping area usually in the Serving cell of MS and adjacent sub-district.Wherein, Serving cell is meant and currently is meant and Serving cell adjacent sub-district on the geographical position for MS provides the sub-district of service, adjacent sub-district.Be understandable that constantly can the changing of the concrete sub-district that Serving cell and adjacent sub-district refer to different.For example, if current is the A sub-district for MS provides the sub-district of service, then B sub-district, C sub-district are the adjacent sub-district of this Serving cell (A sub-district), and along with the reasons such as variation of MS position, when the current sub-district that service is provided for MS becomes the B sub-district by the A sub-district, then Ci Shi Serving cell is the B sub-district, and adjacent sub-district then is A sub-district and C sub-district.And, Serving cell and adjacent sub-district can be arranged in same BTS, also can be arranged in different BTS, for example, suppose that A sub-district among Fig. 3, B sub-district and C sub-district are arranged in a BTS, D sub-district, E sub-district and F sub-district are arranged in another BTS, and then the C adjacent cells of cells comprises A sub-district and the B sub-district that is arranged in same BTS with the C sub-district, also comprise the D sub-district and the E sub-district that are arranged in different BTS with the C sub-district.
When MS was positioned at the covering overlapping area of two sub-districts, MS can send descending level measurement report to BSC, wherein carried descending incoming level of Serving cell and adjacent cell downlink incoming level.For example, be positioned at the covering overlapping area of the sub-district that is in identical BTS as MS, for example, during the covering overlapping area 31 of A sub-district and C sub-district, MS can measure the downstream signal of A sub-district and the transmission of C sub-district respectively, obtain corresponding descending incoming level, afterwards the descending incoming level of A sub-district and the descending incoming level of C sub-district are notified to BSC by descending level measurement report.Equally, be positioned at the covering overlapping area of the sub-district that is in different BTS as MS, for example, during the covering overlapping area 32 of C sub-district and D sub-district, MS can measure the downstream signal of C sub-district and the transmission of D sub-district respectively, obtain corresponding descending incoming level, afterwards the descending incoming level of C sub-district and the descending incoming level of D sub-district are notified to BSC by descending level measurement report.
Step 22:BSC determines whether this MS is in covering overlapping area and determines to comprise the adjacent sub-district of this covering overlapping area.
When the absolute value of the difference of the descending incoming level of Serving cell and at least one adjacent cell downlink incoming level was less than or equal to the overlapping threshold value of covering that sets in advance, BSC determined that corresponding MS is the MS that is in covering overlapping area.If when promptly descending incoming level of Serving cell in the descending level measurement report of a MS and adjacent cell downlink incoming level satisfied following the relation, then this MS was the MS that is in covering overlapping area:
| the descending incoming level of Serving cell-adjacent cell downlink incoming level |≤overlapping level threshold covered.
Be understandable that, when having a plurality of adjacent sub-district,, then can obtain MS and be in covering overlapping area as long as have the adjacent cell downlink incoming level of an adjacent sub-district correspondence and the descending incoming level of Serving cell to satisfy above-mentioned relation.
In addition, the adjacent sub-district of satisfying above-mentioned condition is the adjacent sub-district that comprises covering overlapping area, promptly, if the absolute value of the difference of adjacent cell downlink incoming level and the descending incoming level of described Serving cell is less than or equal to the overlapping thresholding of the covering that sets in advance, determine that described adjacent sub-district is the adjacent sub-district that comprises described covering overlapping area.With the A sub-district is that Serving cell, B sub-district, C sub-district are that adjacent sub-district is an example, if | A cell downlink incoming level-B cell downlink incoming level |≤cover overlapping level threshold, then the B sub-district is the adjacent sub-district that comprises covering overlapping area.If above-mentioned condition is also satisfied in the C sub-district, then the C sub-district is also for comprising the adjacent sub-district of covering overlapping area.
Step 23: when this MS was in covering overlapping area, BSC sent the cooperation indication to the Serving cell of this MS with the adjacent sub-district that comprises covering overlapping area.
Need to prove that the order that sends the cooperation indication to Serving cell equipment and adjacent cell equipment also can send to Serving cell equipment and adjacent cell equipment with the form of broadcasting in no particular order simultaneously.
In addition, the Serving cell in this step corresponds to Serving cell equipment in subsequent step and Fig. 2, and the adjacent sub-district that comprises covering overlapping area corresponds to adjacent cell equipment in subsequent step and Fig. 2.
Step 24: this MS sends first upward signal and second upward signal to this neighbour's cell equipment and service cell equipment respectively.
Need to prove that sending first upward signal and send the order of second upward signal to Serving cell equipment to adjacent cell equipment also can be in no particular order.
In addition, even if do not sending under the situation of cooperation indication, this MS still can send first upward signal and second upward signal to adjacent cell equipment and service cell equipment respectively.
Step 25: adjacent cell equipment will send to Serving cell equipment from first upward signal that MS receives after receiving this cooperation indication.
Wherein, in order further to improve the quality of reception of signal, adjacent cell equipment is after receiving this first upward signal from MS, can carry out interference elimination treatment to this first upward signal earlier, for example adopt and strengthen interference eliminated (Enhanced Interference Cancellation, EICC) technology is handled first upward signal, and first upward signal after handling is sent to Serving cell equipment again.
Wherein, when Serving cell equipment and adjacent cell equipment are positioned at same base station, can be by the minizone passage of inside of base station, adjacent cell equipment will send to described Serving cell equipment from first upward signal that described terminal receives;
Perhaps, when Serving cell equipment is positioned at different base stations with adjacent cell equipment, can be by relaying (backhauling) link between the base station, adjacent cell equipment will send to described Serving cell equipment from first upward signal that described terminal receives.
Step 26: Serving cell equipment merges processing to first upward signal and second upward signal.
Equally, in order further to strengthen received signal quality, Serving cell equipment can carry out EICC to second upward signal earlier to be handled, and afterwards, second upward signal of handling through EICC and first upward signal of handling through EICC is merged processing.
Wherein, merging processing can be that first upward signal and second upward signal are carried out direct addition processing, also can be that first upward signal and second upward signal are weighted the addition processing.And, after merging, processing such as decode further.
Present embodiment can obtain MS comparatively simply and whether be in covering overlapping area by determine to be in the MS of covering overlapping area according to descending level measurement report; By sending the cooperation indication signaling to Serving cell and adjacent sub-district respectively, can make adjacent sub-district and Serving cell Coordination Treatment, improve the accuracy of cooperation; The upward signal and the Serving cell that send by the MS that adjacent sub-district is received directly merge processing from the upward signal that MS receives, rather than only handle the upward signal that MS that Serving cell receives sends, can improve the quality of reception of signal, improve the throughput of speech business speech quality and data service.
For the MS that is in the collaboration communication state, in order to improve the accuracy of switching, third embodiment of the invention also provides a kind of changing method, and as shown in Figure 4, this method can comprise:
The judged result that step 41:BSC sends according to the Serving cell equipment of the measurement report of terminal to report or terminal determines whether described terminal is in covering overlapping area and comprises the adjacent sub-district of described covering overlapping area, and whether wherein said judged result is in covering overlapping area for the measurement report according to terminal to report to described terminal and comprises the judged result of the adjacent sub-district of described covering overlapping area.
If when the descending incoming level of Serving cell in the descending level measurement report of a MS and at least one adjacent cell downlink incoming level satisfied following the relation, then this MS was the MS that is in covering overlapping area:
| the descending incoming level of Serving cell-adjacent cell downlink incoming level |≤overlapping level threshold covered.
Step 42: if described terminal is in covering overlapping area, BSC obtains the described adjacent cell uplink incoming level of described covering overlapping area and the up incoming level of Serving cell of described terminal of comprising.
Wherein, BSC can by with the expansion of the Serving cell equipment of this MS after interface, obtain described adjacent cell uplink incoming level, the adjacent cell equipment of described MS sends to described Serving cell equipment with described adjacent cell uplink incoming level.
Promptly, each sub-district can measure (comprising Serving cell and adjacent sub-district) the up incoming level of self, afterwards, adjacent cell equipment will measure the adjacent cell uplink incoming level of self by and Serving cell equipment between expansion after interface send to Serving cell equipment, afterwards, Serving cell equipment sends to BSC together with the adjacent cell uplink incoming level of adjacent cell equipment transmission and the up incoming level of Serving cell that self measures.Certainly, also can be the adjacent cell uplink incoming level that directly self measured of adjacent sub-district by and BSC between interface send to BSC.
Need to prove, when the equipment of Serving cell need be to BSC cooperative transmission cell uplink incoming level, need the interface between existing Serving cell equipment of expansion and the BSC.In addition, the adjacent cell uplink incoming level that adjacent cell equipment measures self sends to Serving cell equipment, also needs to expand the interface between adjacent cell equipment and the Serving cell equipment.Above-mentioned concrete expansion scheme can be by newly-increased signaling or the existing signaling of expansion, to support the corresponding level of transmission.
Step 43: need to switch if BSC judges, and the difference of described adjacent cell uplink incoming level and the up incoming level of described Serving cell is during more than or equal to the switch level threshold value that sets in advance, sends to switch to described terminal and indicate.
Wherein, BSC judges whether to need to switch that multiple mode is arranged, and specifically can repeat no more with reference to the description of prior art herein.Present embodiment makes the following judgment in a basic enterprising step of existing switching judging in order to improve handover success rate:
When further satisfying following the relation, BSC can send to switch to indicate and show and need switch:
The up incoming level of adjacent cell uplink incoming level-Serving cell＞switch level thresholding.
Wherein, can also further consider sluggish information when judging, this sluggishness information is used to avoid the frequent ping-pong that causes that switches.
For example, the up incoming level of adjacent cell uplink incoming level-Serving cell＞switch level thresholding+sluggishness
