Embodiment
For problems of the prior art, propose a kind of brand-new idle frequence in the present invention and detect and allocative decision.Spectrum controller (SCE is set in mobile cellular net, Spectrum Control Entity), for to control and frequency spectrum detection is carried out in each base station (eNB) in coordination network, and be each base station assigns operating frequency according to the frequency spectrum detecting result that each base station returns.
For make technical scheme of the present invention clearly, understand, to develop simultaneously embodiment referring to accompanying drawing, scheme of the present invention be described in further detail.
Fig. 1 is the flow chart of idle frequence of the present invention detection and distribution method embodiment.As shown in Figure 1, comprise the following steps:
Step 11:SCE determines the base station needing to carry out frequency spectrum detection, and send frequency spectrum detection order to each base station of carrying out frequency spectrum detection that needs, wherein carry the frequency range of detection and the time range of detection, the frequency of described detection is the frequency of authorisation network.
Under initial condition, by human configuration, or control each base station by SCE and carry out spectrum scan to obtain spectrum occupancy state at that time at full working frequency range, thus generate frequency spectrum state table.In scheme of the present invention, which information of preserving concrete in frequency spectrum state table is not restricted, such as, current grant network that each base station detects can be preserved to the service condition of own frequency with for the operating frequency of each base station assigns is (under initial condition, the unallocated operating frequency of possibility, suppose in the present embodiment, the operating frequency that has been manually each base station assigns in advance).
In actual applications, SCE can be an entity arranged separately, also can be arranged in existing network entity, as placed it on existing mobile management entity (MME, Mobility ManagementEntity) or on base station.When SCE is integrated in MME, SCE can be communicated with each base station by S1 interface; When SCE is integrated on base station, SCE can by X2 interface and each base station communication.In addition, also SCE dispersion can be placed on each base station, be communicated by X2 interface between them.As shown in Figure 2, Fig. 2 is the schematic diagram of the present invention when being placed separately by SCE; As shown in Figure 3, Fig. 3 is that SCE is disperseed schematic diagram when being positioned over each base station by the present invention.Certainly, above are only and illustrate, in actual applications, be not limited to aforesaid way.
In order to follow the tracks of the service condition of authorisation network to own frequency, mobile cellular net needs regularly to carry out frequency spectrum detection, to determine whether authorisation network has resumed the idle frequence being originally moved Cellular Networks and taking, or release the frequency self originally taken, and then determine whether to need again for associated base stations shares out the work frequency.For this reason, in the present embodiment, when each arrival timing instant, namely step 11 is performed, namely SCE determines the base station that needs to carry out frequency spectrum detection, and sends frequency spectrum detection order to each base station of carrying out frequency spectrum detection that needs, and wherein carries the frequency range of detection and the time range of detection, the frequency of described detection is the frequency of authorisation network, and whether the frequency use condition namely detecting authorisation network there occurs change.It should be noted that, between twice timing instant in above-mentioned every front and back, the duration at interval can be identical, also can be obstructed, is decided according to the actual requirements.
Consider that the coverage of authorisation network is usually much larger than the coverage of a base station, be in same frequency spectrum take the number of the base station in environment will be more, in order to reduce the expense for frequency spectrum detection, SCE only can select part, instead of frequency spectrum detection is carried out in whole base stations, and the frequency spectrum detecting result of each base station is merged, to obtain overall frequency spectrum detecting result.How SCE determines the base station that needs to carry out frequency spectrum detection and how to determine that the time range etc. of the frequency range that each base station is detected and detection is not all restricted.
In addition, for avoiding producing interference, after determining and needing to carry out frequency spectrum detection base station, also can determine the base station needing to carry out mourning in silence further, the base station of carrying out mourning in silence to each needs sends order of mourning in silence, wherein carry the time range of mourning in silence, described time range of mourning in silence is identical with the time range of described detection, each need the base station of carrying out frequency spectrum detection to carry out frequency spectrum detection while, each need to carry out mourning in silence base station and the UE of subordinate UE and the base station subordinate that respectively needs to carry out frequency spectrum detection all need to mourn in silence.SCE can while sending frequency spectrum detection order to the base station needing to carry out frequency spectrum detection, and the base station of carrying out mourning in silence to needs sends order of mourning in silence, also can different time transmission, and sequencing is not limit.
Suppose that base station A is the base station needing to carry out frequency spectrum detection, if be greater than the threshold value preset when base station B normally works to the interference of base station A, so then can think that base station B is the base station needing to carry out mourning in silence.The concrete value of described threshold value is subject to the impact of following factor: the interval of the frequency that the geographical position relation (as distance) of base station B and base station A, the operating frequency of base station B and base station A will detect, and authorisation network is to the requirement etc. of frequency spectrum detection performance.
It should be noted that, in above-mentioned frequency spectrum detection order and order of mourning in silence, also can carry out of Memory further, due to scheme of the present invention without direct relation, therefore not to be described.
Step 12: respectively need the base station of carrying out frequency spectrum detection to carry out frequency spectrum detection according to the frequency spectrum detection order received, and return frequency spectrum detecting result to SCE.
In this step, respectively need the base station of carrying out frequency spectrum detection to carry out frequency spectrum detection according to the frequency range of detection of carrying in the frequency spectrum detection order received and the time range etc. of detection, and frequency spectrum detecting result is returned to SCE.How to carry out frequency spectrum detection not to be restricted.
Step 13:SCE upgrades the frequency spectrum state table of self according to the frequency spectrum detecting result received, and determines whether there is the base station needing to redistribute operating frequency, if so, then for operating frequency is redistributed in this base station according to the frequency spectrum state table after upgrading.
In this step, first SCE upgrades the service condition of authorisation network to own frequency of preserving in the frequency spectrum state table of self according to receiving frequency spectrum detecting result; Then, whether the situation determination authorisation network of comprehensive each base station there occurs change to the service condition of own frequency, as in certain geographic range, the whether authorized network of certain frequency is resumed or discharges; Afterwards, SCE can, according to the interval etc. of authorisation network to the frequency that the requirement of interference, base station and the distance of authorisation network and the operating frequency of base station and authorisation network take, determine whether to need for operating frequency is redistributed in a certain base station.Such as: resume if the operating frequency of a certain base station is authorized to network, so then need for operating frequency is redistributed in this base station, or, resume if the side frequency of the operating frequency of a certain base station is authorized to network, for avoiding producing interference, also need for operating frequency is redistributed in this base station, again or, if authorisation network releases a certain frequency, and a certain base station uses the frequency of this release to carry out the operating frequency used before communication efficiency can be better than, so also need for operating frequency is redistributed in this base station.
In addition, while for each base station assigns operating frequency, also may further be each base station assigns operating frequency for subsequent use, and be recorded in frequency spectrum state table, in this step, SCE also can determine whether there is the base station needing to redistribute operating frequency for subsequent use after upgrading frequency spectrum state table according to the frequency spectrum detecting result received further, if so, then for operating frequency for subsequent use is redistributed in this base station.
Like this, for a base station, just may occur following three kinds of situations: 1) operating frequency does not need to redistribute, operating frequency for subsequent use needs to redistribute; 2) operating frequency needs to redistribute, and operating frequency for subsequent use does not need to redistribute; 3) operating frequency and operating frequency for subsequent use all need to redistribute.
For the 1st) plant situation, SCE is only required to be base station and redistributes operating frequency for subsequent use, and informs base station, and correspondingly, the operating frequency for subsequent use redistributed, without the need to carrying out frequency error factor, only need be preserved in base station; For the 3rd) plant situation, SCE needs for operating frequency and operating frequency for subsequent use are redistributed in base station, and informs base station, and correspondingly, base station needs to be switched to the operating frequency redistributed, and preserves the operating frequency for subsequent use redistributed; For the 2nd) plant situation, SCE is redistributing operating frequency for base station and before informing base station, operating frequency for subsequent use can be switched to by first informing base station, because operating frequency for subsequent use can be informed to each UE of subordinate by base station in advance, therefore in the operating frequency being first switched to operating frequency for subsequent use instead of redistribute after being switched to, can contribute to reducing UE carry out the time delay of frequency error factor and improve handover success rate, afterwards, the operating frequency redistributed is informed to base station by SCE again, and the operating frequency redistributed is preserved as operating frequency for subsequent use by base station.
Below by a preferred embodiment, scheme of the present invention is further described.
Fig. 4 is the flow chart of idle frequence of the present invention detection and distribution method first preferred embodiment.As shown in Figure 4, comprise the following steps:
Step 41:SCE determines whether to arrive timing instant, if so, then performs step 42, otherwise, repeated execution of steps 41.
Step 42:SCE determines that the base station needing to carry out frequency spectrum detection is base station A, needs the base station of carrying out mourning in silence to be base station B.
Step 43:SCE sends to base station B order of mourning in silence, and wherein carries the time range of mourning in silence.
Step 44:SCE sends frequency spectrum detection order to base station A, wherein carries the frequency range of detection and the time range of detection.
Step 45: base station A carries out frequency spectrum detection, meanwhile, each UE of subordinate (notifying the information such as subordinate UE silence period by base station in advance) of base station B and base station A and base station B mourns in silence.
Step 46: base station A returns frequency spectrum detecting result to SCE.
Step 47:SCE upgrades frequency spectrum state table.
Step 48:SCE determines to need for base station C redistributes operating frequency and operating frequency for subsequent use, and sends operating frequency switching command and operating frequency configuration order for subsequent use to base station C.
Base station C may be base station A or base station B, also may be other base station.
Step 49: base station C is switched to the operating frequency redistributed, and preserve the operating frequency for subsequent use redistributed, then return response message to SCE.
In theory, for understanding the service condition of authorisation network to own frequency in time, need to arrange less frequency spectrum detection period, the interval by twice timing instant in front and back arranges shorter, if but frequency spectrum detection period arranges too short, the expense of frequency spectrum detection can be increased again.In order to the service condition of authorisation network to own frequency can be understood in time, the expense of frequency spectrum detection can be reduced again, can frequency spectrum detection period be arranged larger, then in the gap of double timing instant, the each base station in network is allowed to detect from the interference be subject in operating frequency, and determine to disturb the threshold value whether being greater than and pre-setting, if so, then send frequency spectrum detection application to SCE.If namely interference is greater than threshold value, then can suspect that authorisation network has resumed frequency, this frequency may be the operating frequency of base station, also may be the side frequency of operating frequency.Described interference obtains indirectly by certain measuring amount, and the concrete value of described threshold value can be decided according to the actual requirements.
SCE determines the base station needing to carry out frequency spectrum detection according to the frequency spectrum detection application received, frequency spectrum detection order is sent to each base station of carrying out frequency spectrum detection that needs, and determine the base station that needs to carry out mourning in silence, the base station of carrying out mourning in silence to each needs sends order of mourning in silence; Respectively need the base station of carrying out frequency spectrum detection to carry out frequency spectrum detection according to the frequency spectrum detection order received, and return frequency spectrum detecting result to SCE; SCE upgrades frequency spectrum state table according to the frequency spectrum detecting result received, and determines whether there is according to the frequency spectrum state table after upgrading the base station needing to change operating frequency, if so, then notifies that this base station changes operating frequency, as being switched to operating frequency for subsequent use.
Fig. 5 is the flow chart of idle frequence of the present invention detection and distribution method second preferred embodiment.As shown in Figure 5, comprise the following steps:
Step 51: in the gap of double timing instant, base station A determines that the interference be subject in operating frequency is greater than the threshold value preset, and sends frequency spectrum detection application to SCE.
Step 52:SCE determines that the base station needing to carry out frequency spectrum detection is base station A and base station C, needs the base station of carrying out mourning in silence to be base station B.
Suppose that the operating frequency of base station C is identical with base station A, so base station A and base station C can be defined as the base station needing to carry out frequency spectrum detection simultaneously.
Step 53:SCE sends to base station B order of mourning in silence, and wherein carries the time range of mourning in silence.
Step 54:SCE sends frequency spectrum detection order to base station A and base station C, wherein carries the frequency range of detection and the time range of detection.
In this case, the frequency range of described detection can only include the operating frequency of base station A and base station C and the side frequency of operating frequency, or comprises both operating frequencies for subsequent use and the side frequency of operating frequency for subsequent use further.
Step 55: base station A and base station C carries out frequency spectrum detection, meanwhile, each UE of base station B and base station A, base station B and base station C subordinate mourns in silence.
Step 56: base station A and base station C returns frequency spectrum detecting result to SCE.
Step 57:SCE upgrades frequency spectrum state table.
Step 58:SCE determines to need base station A and base station C to be switched to operating frequency for subsequent use, sends switch to operating frequency command for subsequent use to base station A and base station C.
Step 59: base station A and base station C is switched to operating frequency for subsequent use, and returns response message to SCE.
In actual applications, be likely because other reason causes interference to increase, and frequency spectrum detecting result display operating frequency not problem itself, so then without the need to being switched to operating frequency for subsequent use.
In addition, SCE is after determining and needing to be switched to operating frequency for subsequent use, also can determine whether operating frequency for subsequent use can be used further, such as, likely frequency spectrum detecting result show operating frequency for subsequent use also authorized network resume, or the side frequency of operating frequency for subsequent use is authorized to network and resumes, so then determine that operating frequency for subsequent use is unavailable, in this case, can not send to base station A and base station C and switch to operating frequency command for subsequent use, but wait until next timing instant, be that base station A and base station C redistribute operating frequency and operating frequency for subsequent use according to mode shown in Fig. 1, and then be switched in the operating frequency redistributed.In addition, for reducing frequency spectrum detection burden, the frequency range detected in step 54 can not comprise the operating frequency for subsequent use of base station A and base station C and the side frequency of operating frequency for subsequent use, in this case, SCE cannot determine whether the operating frequency for subsequent use of base station A and base station C can be used, so after determining that base station A and base station C needs to be switched to operating frequency for subsequent use, can send to base station A and base station C and switch to operating frequency command for subsequent use, afterwards, oneself determine whether operating frequency for subsequent use can be used by base station A and base station C, how to determine not to be restricted, if unavailable, then find available free frequency according to existing mode, and coordinate with SCE.
