Description
Technical field
The present invention relates to the communications field, relate in particular to the technology of transmission compossibility message.
Background technology
Along with the development of wireless communication technology, more and more stronger to the demand of radio spectrum resources.Because radio spectrum resources is very limited, therefore need to improve the utilance of radio spectrum resources, particularly authorize the utilance of the frequency spectrum resource of frequency range.
In order to improve the utilance of radio spectrum resources, many communication technologys that take full advantage of the idle frequency spectrum resource had been proposed in recent years, such as cognitive radio technology etc.In described cognitive radio technology, stipulate, support the wireless device of cognitive radio technology to want the dynamic sensing surrounding environment, and according to the variation of surrounding environment, dynamically adjust adaptively its internal state.Whether on the other hand, when initially entering network in new base station, need to adopt certain frequency spectrum sensing method, detecting has other base station to take this frequency range, if can detect idle channel, then selects this channel as the working channel of oneself.If can't detect idle channel, then corresponding sub-frame allocation mode need to be adopted in new base station, such as a kind of method of salary distribution of time-sharing channel, shares some channels with neighbor base stations on every side.
At present, generally have following several subframe type: have the system of higher priority, with the time period that maximum power is launched, be called boss's frame of this system, this system is called main system accordingly; And section adopts other communication system of same channel at one time, then must reduce the transmitting power of oneself even mourns in silence, and to avoid the interference to main system, this time period is called the auxiliary subframe of system.Be in the base station center place for those, be not subject to the business of the terminal of neighbours' interference, then each base station can be transmitted the business relevant with these terminals simultaneously, and to improve the availability of frequency spectrum, this subframe is called common subframe or shared subframe.
The sub-frame allocation mode can have multiple, and take system shown in Figure 1 as example, Fig. 2 has provided a kind of sub-frame allocation mode of a kind of realization time-sharing channel.In common subframe and shared subframe, system A transmits the data relevant with terminal 1 and terminal 2, and simultaneously, system B transmits the data relevant with terminal 5 and terminal 6.At boss's frame of the A of system, system A communicates by letter with terminal 3, and system B need to reduce at this moment transmitting power and even not launch, thereby avoids the A of system is produced interference; At boss's frame of the B of system, system B communicates by letter with terminal 4, and system A need reduce at this moment transmitting power and even not launch, thereby avoids the B of system is produced interference.
At present, the method for the auxiliary Interference Detection of terminal is generally adopted in each base station, and the situation of the neighbor base stations around finding in order in time adjust the transmitting power of oneself, is avoided interference each other.Still take the described system of Fig. 1 as example, the process by the auxiliary Interference Detection of terminal comprises as shown in Figure 3:
Base station A broadcasts the compossibility MAC layer information of communicating by letter with neighbours of oneself being used for by eating dishes without rice or wine; Terminal 4 in the coverage of base station A detects the compossibility message from interference neighbors base station A, and the broadcast singal of the base station A that detects is passed to the serving BS B of oneself; The signal that base station B reports according to terminal 4 can be learnt to have interference neighbors base station A, and the notice backbone network detects interference neighbors base station A; Afterwards, there is interference neighbors base station B in backbone network informing base station A.
The method that the prior art relevant with the present invention provides the base station to broadcast compossibility MAC layer message by eating dishes without rice or wine, it adopts following two kinds of transmission meanss:
The first transmission means is to utilize at CSI(Coexistence Signaling Interval, compossibility signaling interval) energy pulse of sending out transmits these MAC layer message, namely with having Energy Transfer and noenergy to transmit to represent binary zero and 1, perhaps the length with burst transmissions represents binary zero and 1.The transmission technology that this mode and physical layer adopt is irrelevant, therefore is adapted to the system communication between the different physical layers.
It is leading that this transmission means need to be transmitted Preamble(), and adopt comparatively healthy and strong modulation coding mode, therefore taking the transmission time longer, energy pulse length is longer; Be that every frame all will transmit owing to compossibility signaling interval in addition, thereby cause the waste of interface-free resources.
The second transmission means is for utilizing CMI(Coexistence Message Interval, the compossibility message interval) carries out MAC layer transmission of messages, described CMI is the time slot of allocating transmission compossibility MAC layer message in advance, as in some present agreements, definition is every 20ms, reserve one and be approximately the 1.9ms time slot, be specifically designed to transmission compossibility MAC layer message, and do not carry out transfer of data.Described CMI comprises up CMI and descending CMI.Descending CMI is used for base station broadcast compossibility message, such as BSD(Base Station Descriptor, base station descriptor), comprise the IP address of base station, the ID of base station, and some are such as other information relevant with compossibility such as RF sector numbers; Up CMI is used for terminal to neighbor base stations transmission compossibility message, such as SSURF(Subscriber Station Uplink RF Descriptor, user uplink radio frequency descriptor), comprise the ID of Terminal Service base station, the IP address of serving BS etc.
By the compossibility MAC layer message of eating dishes without rice or wine to transmit, except BSD, SSURF, some broadcasts that also have other, more for example be used for the message that dynamic boss's frame distributes, such as MADD(Master Advertisement Discovery Descriptor), SADD(Slave Advertisement Discovery Descriptor), ADPD(Advertisement Discovery Policy Descriptor); The MAC layer message that perhaps is used for compossibility neighbours communication is such as CXP-REQ-MAC(Coexistence Protocol Request MAC Message), CXP-RSP-MAC(Coexistence Protocol Response MAC Message) etc.
Can be found out by the second transmission means, it need to reserve specific resource for compossibility MAC layer message, thereby has taken valuable interface-free resources; In addition, because the recipient adheres to different systems separately with transmit leg, do not carry out in advance synchronizing process, in order to guarantee that the recipient can reliable reception, transmit leg need to arrange meticulously to the message that sends, and for example needs to comprise long leading Preamble, adopts the PHY profile(that consults at the whole network in advance to comprise the channel, subcarrier etc. of modulation system, coded system, use) etc., thereby increased complexity, and limited range of application.

Embodiment
The first embodiment that the present invention passes through is a kind of coexistence message transmission method, and it not only realize simply, and it is few to take interface-free resources by transmission compossibility MAC layer message in boss's frame of base station.Its realization flow comprises as shown in Figure 4:
Step S101, a base station selected glitch-free subframe, and with described subframe as boss's frame, by described boss's frame, broadcast the compossibility message of oneself.
Described compossibility message comprises: the ID of base station; Perhaps, the IP address of base station; Perhaps, the agency's of base station IP address.The antenna sector number that can also comprise the base station; Perhaps, the GPS(Global Positioning System of base station, global positioning system) positional information; Perhaps, the subframe numbers of base station.Perhaps, be used for the message that dynamic boss's frame distributes, such as the information that comprises in the type of messages such as MADD, SADD, ADPD; Perhaps, for the compossibility MAC layer message of communicating by letter with neighbor base stations, such as the information that comprises among CXP-REQ-MAC, the CXP-RSP-MAC.
Step S101 specifically can adopt two kinds of methods to realize:
The first: be a class compossibility message, distribute a management message type; By boss's frame, described management message type and a corresponding class compossibility message thereof as an administrative messag of base station, are transferred out.
For example, comprise the agency's (Proxy) of the IP address of base station IDs, base station or base station IP address for present BSD(), the MAC message of the compossibility such as MADD, SADD, PADD, distribute respectively a management message type; Boss's frame in the base station is broadcasted compossibility MAC message corresponding to each management message type.
The second: with a class compossibility message, as the newly-added information unit, be attached in the administrative messag of a standard of base station; Transmit the administrative messag of described standard by boss's frame of base station, described compossibility transmission of messages is gone out.
For example, at existing DL-MAP(Down Link Mapping, descending mapping) in the message (ID that comprises the base station), increase an extended message type, be used for the IP address that transmission comprises the agency (Proxy) of the IP address of base station or base station, and the compossibility message of other information relevant with compossibility, such as the position of base station GPS.Perhaps, in existing DL-MAP message, increase new TLV(Type Length Value) type of message, the IP address of transmission base station or the agency's of base station IP address, perhaps the compossibility message of other information relevant with compossibility.Owing in existing DL-MAP, having transmitted the ID of base station, therefore, when transmission compossibility message, can not repeat to transmit base station IDs.
Compossibility message can be transmitted in each boss's frame of base station; Also can that is to say by certain boss's frame transmission of base station, do not transmit at each boss's frame, may be in certain the boss's frame behind several boss's frames transmission primaries compossibility message, with further saving resource.
Step S102, terminal receives the signal from neighbor base stations in boss's image duration of non-serving base stations; From the administrative messag of boss's frame transmission of the neighbor base stations that receives, extract the compossibility message of neighbor base stations, and according to the mechanism that reports of compossibility message, with described compossibility information reporting to serving BS.
Among the step S102, terminal can be in each boss image duration of non-serving base stations, reception is from the signal of each non-serving base stations, therefrom determine the signal of neighbor base stations, perhaps, terminal receives signal from each non-serving base stations image duration certain boss of non-serving base stations, therefrom determines the signal of neighbor base stations.That is to say, terminal no longer boss's frame of each non-serving base stations receives, and may receive by the some or a plurality of boss's frames behind several boss's frames.
Terminal can have following several situation with the process of compossibility information reporting to serving BS:
After the first, terminal whenever detect the compossibility message of neighbor base stations, just with described compossibility information reporting to serving BS.
Terminal to report compossibility message is to having three kinds the opportunity of serving BS:
Terminal can report compossibility message to serving BS immediately; Can work as the time interval of identical compossibility message when surpassing a certain specific value apart from terminal to report same neighbourhood base station last time, report compossibility message to serving BS; After can by the time receiving the compossibility information reporting request from serving BS, report compossibility message to serving BS.
After the second, terminal detect the compossibility message of same neighbourhood base station at several times, with described compossibility information reporting to serving BS.
Terminal to report compossibility message is to the opportunity of serving BS in the second situation, and is similar with the first situation, no longer describes here.
The third, terminal if terminal has been crossed the compossibility message of described neighbor base stations to serving base stations report, does not then report after detecting the compossibility message of neighbor base stations; If terminal is never crossed the compossibility message of described neighbor base stations to serving base stations report, then with described compossibility information reporting to serving BS;
Terminal to report compossibility message is to the opportunity of serving BS in the third situation, and is similar with the first situation, no longer describes here.
The 4th kind, after terminal detects the compossibility message of neighbor base stations, and the compossibility message of finding same base station is when having renewal, then with described compossibility information reporting to serving BS.
Terminal to report compossibility message is to the opportunity of serving BS in the 4th kind of situation, and is similar with the first situation, no longer describes here.
The 5th kind, after terminal detects the compossibility message of neighbor base stations, and the compossibility message of finding same base station is when having renewal, only selects the part upgraded in the described compossibility message, reports serving BS.Terminal to report compossibility message is to the opportunity of serving BS in the 5th kind of situation, and is similar with the first situation, no longer describes here.
The 6th kind of situation, after terminal detects the compossibility message of neighbor base stations, and the lookup service base station has obtained the compossibility message of neighbor base stations, but serving BS does not know that terminal is to be disturbed terminal, then terminal can to serving base stations report oneself be this neighbor base stations newly-increased be disturbed terminal.
Terminal to report compossibility message is to the opportunity of serving BS in the 6th kind of situation, and is similar with the first situation, no longer describes here.
The below describes step S102 for example:
Suppose compossibility message as a part of information unit transmission of the DL-MAP message of standard, neighbor base stations broadcasting has comprised the DL-MAP message of compossibility message, and the DL-MAP message process of terminal reception this moment neighbor base stations broadcasting is as follows:
It is synchronous that terminal is at first carried out down physical layer, obtains the position of frame head position and each subframe;
After each subframe head arrived, terminal synchronizes was to this subframe head, and the DL-FCH(Down Link Frame Control Hander behind the reception Preamble, the downlink frame control head);
For the OFDMA physical layer, terminal need to be at each frame head and subframe head place, and relevant with all local Preamble sequences according to correlated results, determined the cell signal that receives, further separates the DL-FCH of these residential quarters.For example, terminal need to being correlated with of all local Preamble sequences, be got the corresponding cell ID of the corresponding Preamble sequence of relevant peaks and the segment ID of certain thresholding at each frame head and subframe head place, further separated the DL-FCH of these residential quarters.
If can be correctly decoded DL-FCH, then according to the information of DL-FCH, decipher first burst, if can correct decoding, then according to the DL-MAP message that obtains, therefrom extract the compossibility message of neighbor base stations; If can not correct decoding DL-FCH, perhaps can not first burst of correct decoding, then abandon other data after this subframe, until next subframe head.
When terminal extracts the compossibility message of neighbor base stations from the DL-MAP message of correct reception after, then according to the above-mentioned mechanism that reports, determine the compossibility message that need to report serving BS, and above-mentioned several on time signal machine, it is reported the serving BS of oneself.
Step S103 behind the ID of the neighbor base stations that the service terminal of serving BS acquisition oneself reports, thinks that then this neighbor base stations is the interference neighbors base station of oneself.
Afterwards, after serving BS further obtains the IP address of interference neighbors base station or described interference neighbors base station agency's IP address, just can be by backbone network or Intranet(internet) communicate by letter with described neighbor base stations.
In order to support up compossibility transmission of messages, the second embodiment of the present invention provides another kind of coexistence message transmission method, in the method, terminal for the signal that can receive serving BS and neighbor base stations, can be used as link terminal and be linked into neighbor base stations, the request neighbor base stations is the ascending resource that oneself distributes transmission trunking message, then utilizes the ascending resource that is assigned to, and transmits up compossibility message to neighbor base stations.
Terminal is linked into neighbor base stations as link terminal access procedure is identical with the process of ordinary terminal access base station, just terminal need to be informed the base station by certain mode (for example by an information unit), oneself be for relay message accesses, rather than access for request service.
The third embodiment of the present invention provides a kind of compossibility massage transmission device, and its structure comprises as shown in Figure 5: selected cell and transmission unit.

Wherein, acquiring unit can receive each boss of the non-serving base stations of terminal the signal from neighbor base stations image duration; Also can receive certain boss of the non-serving base stations of terminal the signal from neighbor base stations image duration.That is to say, acquiring unit no longer boss's frame of the non-serving base stations of each terminal receives, and may receive by the some or a plurality of boss's frames behind several boss's frames.
Report the unit, according to the mechanism that reports of compossibility message, the compossibility information reporting that described acquiring unit is extracted is to serving BS.Its disposition is as follows:
