Embodiment
In following narration, many ins and outs have been proposed in order to make the reader understand the application better.But, persons of ordinary skill in the art may appreciate that even without these ins and outs with based on the many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that execution mode of the present invention is done to describe in detail further below.
First execution mode relates to a kind of with the Cellular Networks of frequency and the fusion method of other wireless access network, and its flow process is as shown in Figure 1.
In step 101, other wireless access network node obtains the timing information of Cellular Networks through Cell searching.
Other wireless access network can be various types of, for example: the peer-to-peer network between sensing net, base station from home, WLAN (Wireless Local Area Network is called for short " WLAN "), the wireless terminal, blueteeth network or the like.
After this get into step 102, Cellular Networks is suspended emission in the time slot of appointment.The time slot of appointment can be time slot of reserving on the up-downgoing transfer point of Cellular Networks of ascending time slot, time division duplex of descending time slot, the emission of Cellular Networks end side of Cellular Networks network side emission or the like.
After this get into step 103, only launch in the time slot that Cellular Networks is suspended emission with other wireless access network node of frequency, can make like this Cellular Networks not can with other wireless access network mutual interference mutually with frequency.
The example that above-mentioned steps is reflected on the frame structure is as shown in Figure 6; The frame of a Cellular Networks comprises 6 time slots among Fig. 6, and from 0 to 5 numbering is at time slot 0 and time slot 1 (time slot that is equivalent to appointment); Cellular Networks is suspended emission, and other wireless access network node is only in time slot 0 and time slot 1 emission; And from time slot 2 to time slot 5, the Cellular Networks emission, other wireless access network node suspends emission.
Have under a plurality of scenes at other wireless access network node, can adopt multiple mode to coordinate,, give some instances below with each other wireless access network node conflict each other during avoiding the Cellular Networks time-out to launch.
One, a plurality of other wireless access network nodes are set up Ad hoc network earlier, and each node is confirmed transmission time slot separately through consultation, perhaps is set in the token that transmits between each node, only obtains the token node and just can launch.It is the situation of same type that this mode comparatively is fit to each node, for example the sensing net.
Two, adopt the mode of carrier sense collision detection; Specifically each other wireless access network node is intercepted earlier in the time slot of appointment, if other node emission is arranged then wait; If there is not other node emission; Then in the emission of next available gap, if detect collision, rollback N interval (N can be a random number) then.
Three, each access network node is to the time resource of cellular network node application emission, by the Cellular Networks uniform dispatching, specifically referring to second execution mode.
The Cellular Networks of mentioning in each execution mode of the present invention is not limited to the TDD network; It also can be the network of other type; FDD network for example, perhaps TDD and FDD hybrid network etc., Cellular Networks can also adopt CDMA; OFDM technology such as (Orthogonal Frequency Division Multiplexing are called for short " OFDM ").
If FDD network; In order to obtain effect preferably; Preferred scheme be on the retention time between each sub-district of FDD network synchronously, in order to avoid other wireless access network node receives the interference of a plurality of neighbor cells in the FDD network simultaneously, increase the difficulty of the network integration.
Second execution mode relates to a kind of with the Cellular Networks of frequency and the fusion method of other wireless access network, and its flow process is as shown in Figure 2.
In step 201, other wireless access network node obtains the timing information of Cellular Networks through Cell searching.
After this get into step 202, other wireless access network node is linked into Cellular Networks.
After this get into step 203, other wireless access network node sends the request of application resource launch time to Cellular Networks.Can carry this node types sign in this request, Cellular Networks is carried out the scheduling of time resource according to this node types.
After this get into step 204, Cellular Networks is carried out the scheduling of time resource.Can dispatch according to the factors such as load of the current total load level of Cellular Networks, the current real time business of Cellular Networks.For example when the current total load level of Cellular Networks is lower than certain thresholding for application resource launch time other wireless access network node distribute time resource.
By Cellular Networks uniform dispatching time resource, can improve utilization ratio of wireless resources, and prevent the phase mutual interference between a plurality of other Access Networks for it distributes time resource when other wireless access network node need be launched.Because the ability of Cellular Networks network equipment is stronger usually, so can not produce significant burden to Cellular Networks by Cellular Networks uniform dispatching time resource.
After this get into step 205, Cellular Networks will allow the time slot (being scheduling result) of other wireless access network node emission to notify other wireless access network node.Scheduling result can be to specify N cycle, has one or more time slots to distribute to other wireless access network node in each cycle.If N end cycle, other wireless access network node have not also passed, then can continuation application.Also can not limit lasting periodicity in the scheduling result, other wireless access network node has passed back notice Cellular Networks, and Cellular Networks reclaims the transmission that this time resource is used for own service.
After this get into step 206, Cellular Networks is suspended emission according to scheduling result in the time slot of appointment (promptly allowing the time slot of other wireless access network node emission).
After this get into step 207, other wireless access network node is launched in the time slot of appointment (promptly allowing the time slot of other wireless access network node emission) according to scheduling result.
The 3rd execution mode relates to a kind of with the Cellular Networks of frequency and the fusion method of other wireless access network, and the 3rd execution mode improves on second execution mode.
In the 3rd execution mode, there are a plurality of other wireless access network nodes in the Cellular Networks coverage, these nodes are provided with different priority, and priority can static allocation also can dynamically arrange.
In step 204, when Cellular Networks is carried out the scheduling of time resource, take all factors into consideration the current load of Cellular Networks and the priority of other wireless access network node of filing a request.
For example, two kinds of other wireless access network nodes are arranged, a kind of is sensing net node, and a kind of Home eNodeB supposes that sensing net node is a low priority, and Home eNodeB is a high priority.If Home eNodeB has proposed request, then Cellular Networks is preferably its distribution time resource.If sensing net node has proposed request, then Cellular Networks is that sensing net node distributes time resource when the own service load is lower than thresholding; When the own service load is higher than thresholding,, or only distribute the time resource of minimum not for sensing net node distributes time resource.
The 4th execution mode relates to a kind of with the Cellular Networks of frequency and the fusion method of other wireless access network, and its flow process is as shown in Figure 3.
This execution mode is that example describes with Long Term Evolution (Long Term Evolution is called for short " LTE ") network and sensing net, and Fig. 5 shows the form of the short frame of LTE of TDD mode; The radio frames of time domain 5ms is divided into the time slot of 5 1ms, is numbered 0,1 respectively; 2,3,4.Wherein 0 time slot is a descending time slot, and 2 time slots are ascending time slots, and what the configuration of 3 time slots and 4 time slots can be for " go up on ", " up and down ", " following " three kinds of configuration modes is a kind of.That selects for use among Fig. 1 is configured to " up and down ", at 3 time slots and 4 time slot intersections individual up-downgoing transfer point is arranged.In addition, 1 time slot is divided into descender (Downlink Pilot Time Slot is called for short " DwPTS "), and protection is (Guard Period is called for short " GP ") at interval, three parts of ascender (Uplink Pilot Time Slot is called for short " UpPTS ").
In sensing net one side, in step 301, the timing information that Cell searching obtains the time division duplex Cellular Networks is crossed by sensing Netcom.Specifically, sensing net node obtains the timing information of this time division duplex Cellular Networks through accomplishing the cell search process of time division duplex Cellular Networks.Cell searching is a kind of mature technique, implements more convenient.Be appreciated that sensing net node also can obtain the timing information of time division duplex Cellular Networks through alternate manner, for example can be provided with the timing information of time division duplex Cellular Networks artificially at sensing net node.
In time division duplex Cellular Networks one side, in step 302, the time division duplex Cellular Networks positions the Cellular Networks terminal of inserting present networks.The time division duplex Cellular Networks has also write down the position of sensing net node before this, can be to be arranged by initial sensing network to obtain; Also can, sensing net node obtain when inserting Cellular Networks through the Cellular Networks location survey; If global positioning system (Global PositionSystem is called for short " GPS ") function is arranged on the sensing net node, also can the positional information that measured be passed to Cellular Networks.
After this get into step 303, according to the result of location, the time division duplex Cellular Networks is judged; The distance of Cellular Networks terminal and sensing net node is less than predetermined threshold; And the distance of this sensing net node and time division duplex cellular network base stations is less than (Tg-T) * c/2, if execution in step 304 then, and the duplexing Cellular Networks of said branch descending-up time slot when wherein Tg is; T is required launch time of said sensing net, and c is the light velocity.Predetermined threshold is maximum effect distance of Cellular Networks terminal for sensing net node, can obtain through the network planning or actual measurement.
In step 304, the time division duplex Cellular Networks is the resource of first ascending time slot after allocation of downlink-up time slot not, and the notice sensing net node can use descending-up time slot and first ascending time slot (like time slot among Fig. 5 2) to transmit.The time division duplex Cellular Networks is carried the information that expression can be used first ascending time slot through the notice sensing net node that sends a notification message at broadcast channel or DCCH in this notification message.
In sensing net one side, in step 305, sensing net node judges whether to obtain the notice of using descending-up time slot and first ascending time slot to transmit from the time division duplex Cellular Networks, after this gets into step 306.
In step 306; If sensing net node obtains the notice of using descending-up time slot and first ascending time slot to transmit from the time division duplex Cellular Networks; Then transmit with first ascending time slot, otherwise only transmit in the descending-up time slot of this time division duplex Cellular Networks in the descending-up time slot of this time division duplex Cellular Networks.
Sensing net node transmits in the descending-up time slot of time division duplex Cellular Networks, can avoid two effectively with the phase mutual interference between the network of frequency, has particularly avoided the obstructing problem of the wireless signal of Cellular Networks to the sensing net.
If the Cellular Networks terminal may produce sensing net node and disturb; Thereby make sensing net node can't obtain time enough and accomplish glitch-free signal emission; Then Cellular Networks can not distributed the resource of first ascending time slot; Give sensing net node with this time slot and transmit, thereby make the sensing net obtain bigger launch window.
Abandoning first ascending time slot with the time division duplex Cellular Networks in this execution mode is that example describes; Be appreciated that under the certain applications scene Cellular Networks also can be abandoned other time slot; For example abandon last descending time slot; Perhaps abandon first and second ascending time slots, with the launch window of further expansion sensing net, or the like.
The time division duplex Cellular Networks has multiple to the method that the Cellular Networks terminal of inserting present networks positions in the step 302; Can utilize global positioning system (the Global Position System on the terminal; Abbreviation " GPS ") function directly obtains location information of terminals, also can be through the position of measuring terminals to distance (can estimate through the time delay) computing terminal of several adjacent base stations (location aware).
Fifth embodiment of the invention relates to a kind of with the Cellular Networks of frequency and the fusion method of other wireless access network, and its flow process is as shown in Figure 4.
In step 401, configuration suspends the time slot of emission in Cellular Networks.
The pattern of the time slot of the time-out emission of disposing in the Cellular Networks can periodically change by the time, thereby improved utilization ratio of wireless resources on the whole.Concrete pattern can be obtained by the statistics of local Cellular Networks load variations, also can rule of thumb be obtained by the webmaster personnel.For example:
For Administrative Area, Mon-Fri 8:00-18:00 distributes less time resource to give other wireless access network, and the more time resource of resource allocation is given other wireless access network At All Other Times.
For residence area, 23:00 to next day 7:00 distribute more time resource to give other wireless access network.
Certainly, the time slot that Cellular Networks is suspended emission also can be relatively-stationary, does not regularly change in time.
After this get into step 402, other wireless access network node obtains the timing information of Cellular Networks through cell search process.
After this get into step 403, Cellular Networks is suspended the information of the time slot of emission through broadcast channel or other wireless access network node Cellular Networks of dedicated channel signaling.If with dedicated channel signaling method notice, other wireless access network node need be linked into Cellular Networks in advance.
More for a long time, can issue the time slot information that Cellular Networks is suspended emission through the mode of broadcasting in other wireless access network node quantity, the efficient of this advice method is higher, and other wireless access network node need not to sign in to Cellular Networks.
When other wireless access network node negligible amounts, can suspend the time slot information of emission through dedicated channel signaling issue Cellular Networks, can only issue in needs.
After this get into step 404, Cellular Networks is suspended emission in the time slot of appointment.
Step 405 is carried out with step 404 simultaneously, only launches in the time slot (i.e. the time slot of appointment) of this Cellular Networks time-out emission with other wireless access network node of frequency with Cellular Networks.Other wireless access network node is emission when Cellular Networks is suspended emission only, can make Cellular Networks not can with other wireless access network mutual interference mutually with frequency.
