Description
Technical field
The present invention relates to the wlan system technical field, in particular to a kind of for the dispatching device between the multi-radio of wlan system and dispatching method.
Background technology
In WLAN(Wireless Local Area Network, WLAN) in system, exist the situation that a plurality of radio-frequency modules coexist.Be limited to the implementation of WLAN agreement, in the system coexisted at a plurality of radio-frequency modules, synchronization can only have a radio-frequency module job, receives or send data.Can mutually produce and disturb if a plurality of radio-frequency modules are worked simultaneously, cause bust this.Therefore need to adopt certain coordinated scheduling algorithm in the system coexisted at multi-radio, avoid producing and disturbing between each radio-frequency module.
Interference problem while coexisting for the solution multi-radio in existing wlan system has following solution usually:
1) adopt different channels between the different radio frequency module, use nonoverlapping frequency resource can guarantee between each radio-frequency module interference-free.
2) utilize the CDMA/CS requirement in the WLAN agreement, each radio-frequency module is monitored interface-free resources, and when eating dishes without rice or wine the free time, each radio-frequency module preempting resources is received and dispatched.
The defect of technique scheme is:
For 1) scheme, system need to take more frequency spectrum resource and evade interference, and the open spectrum resource-constrained of wlan system, this mode is wasted frequency spectrum resource, can't under the large-scale network-estabilishing environment, apply.
For 2) scheme, eat dishes without rice or wine that it is low to monitor efficiency, and can the work of A module occur due to the antenna directional angle difference time, the channel that the B module listens to is idle, thereby the B module starts to transmit and interferes with the situation of A module; Moreover modules follows is free competition, transmitting-receiving priority equalization, can't adjust according to service needed the priority of each module work.
Therefore, need a kind of new technical scheme, can save frequency spectrum resource, work in an orderly manner between each radio-frequency module of coordinated scheduling simultaneously, avoid the conflict produced because freely seizing channel.

In this technical scheme, between the radio-frequency module in different channels, can carry out transfer of data.
Fig. 3 shows the concrete structure figure of dispatching device according to an embodiment of the invention.
As shown in Figure 3, when utilizing this dispatching device to realize a plurality of radio-frequency modules 302 in same channel are controlled, mainly comprise the following steps:
1) obtain from each radio-frequency module 302 and send index signal Itx or receive index signal Irx, wherein, when transmission index signal Itx being detected, mean that this radio-frequency module 302 is in sending data, when reception index signal Irx being detected, mean that this radio-frequency module 302 is in receiving data.
2) by current Itx or the Irx signal of whether detecting from each radio-frequency module 302, and the Itx specifically detected or Irx all deliver in scheduling arbitration unit 304, this scheduling arbitration unit 304 has or not or type according to the index signal of each radio-frequency module 302, thereby judge the residing state of each radio-frequency module, to allow by dispatching algorithm or to forbid that a certain radio-frequency module is received or send the operation of data.
3) principle that realizes of dispatching algorithm is: when all radio-frequency modules 302 all are not in reception or transmission state, could allow some or several radio-frequency modules 302 to start to send data (can allow to send by sending tx control instruction), when having any radio-frequency module 302 to start to send data, should forbid immediately all the other radio-frequency module 302 transceiving datas; Until while not having the data that need to send, then allow all radio-frequency modules 302 to carry out data receiver (specifically can allow to send by sending tx control instruction, allow to receive by sending rx control instruction).
4) when having a plurality of data to be sent, it is stored in one or several transmit queue 306, after a certain radio-frequency module 302 is allowed to send, take out corresponding data with for sending from transmit queue 306.
In sum, the digital signal that scheduling arbitration unit 304 received RF modules 302 produce, judge successively the state of radio-frequency module 302, and provide according to the state of each radio-frequency module 302 control signal that allows or forbid each radio-frequency module 302 work.Each independently the sending permission unification of radio-frequency module 302 by scheduling arbitration unit 304, controlled, determine that by scheduling arbitration unit 304 which radio-frequency module 304 can carry out transmit operation.
Wherein, the implementation method of scheduling arbitration unit 304 is not unique, and it can use independently programmable logic cells to realize, also can utilize the central processing unit resource of wlan system self to be realized by software.
Simultaneously, aspect the obtaining of the index signal to radio-frequency module 302, in a kind of situation, in order to simplify control, the signal that scheduling arbitration unit 304 can be obtained from radio-frequency module 302 is reduced to a signal, such as for originally having proposed Itx and Irx signal, no longer distinguish it for Itx or Irx, and only judge whether to exist this signal, if exist, illustrate that this radio-frequency module 302, in sending or receiving in the state of data, if do not exist, illustrates that this radio-frequency module 302 is in idle condition; In another kind of situation, in order more precisely to control, scheduling arbitration unit 304 can also obtain the state that more condition indicative signal is used for adjudicating radio-frequency module from radio-frequency module 302, as channel idle indication, reception transmit button switching state signal etc.
In addition, in technical scheme of the present invention, equally can be in conjunction with multi channel processing mode, such as a plurality of radio-frequency modules 302 are divided into to a plurality of groups, each group is used identical channel, do not adopt different channels between on the same group, thereby all can adopt above-mentioned scheduling controlling scheme for each group, for can not carry out respectively the transmitting-receiving of data between on the same group simultaneously; And, can independent scheduling arbitration unit 304 be set for each group, or be controlled by 304 pairs all groups of scheduling arbitration units.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered in correlation technique, the interference problem of the multi-radio of wlan system has not been adopted to effective solution.So, the invention provides a kind of dispatching device and dispatching algorithm of the multi-radio for wlan system.By technical scheme of the present invention, each radio-frequency module state can be accurately known and the transmitting-receiving sequential of each radio-frequency module can be precisely controlled, avoid between modules producing conflict, thereby can make a plurality of radio-frequency modules be operated in same channel, save frequency spectrum resource.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
