Description
Technical field
A kind of synchronization slot that the present invention relates to mobile communication is adjusted inking device automatically, and is particularly a kind of based on satellite synchronous automatic inking device of radio network repeater time slot and adjustment collocation method.
Background technology
Along with the development of mobile data services, the 2G frequency resource that makes China is faced with exhausted danger.Development 3G, the demand and the high-end consumers that satisfy the mobile voice that grows at top speed simultaneously are imperative to the demand of high-speed mobile data service.
In three international standards of 3G; TD-SCDMA is the technical standard that China has independent intellectual property right, is subjected to the policy protection of country, simultaneously; the commercialization process has also obtained the extensive approval of operator at present, has bright prospect in the huge 3G network market of China.
The repeater be can receive at up-down bidirectional, the equipment of the RF signal of amplification and emission space radiation (wireless introducing mode) or cable and optical cable conduction (wired introducing mode), exist at outdoor station under the situation of capacity more than needed, can outdoor signal be introduced indoor coverage hole by the repeater, the repeater simple installation flexibly, instant effect, the cycle is short, cost is also lower, is suitable for the indoor covering of low telephone traffic, small and medium construction.The underground parking of large-scale office building covers the good place that is to use the repeater, and underground system has natural isolation, need not consider the signal problem that leaks, and not have capacity requirement, and it covers is again the necessary component that guarantees the key area quality.As the expansion of the covering of suburb signal, the repeater also be a kind of fast and economic means.Therefore, the TD-SCDMA repeater will be one of indispensable equipment of the TD-SCDMA network coverage
TD-SCDMA adopts time division duplex, is different from the FDD mode of operation, needs synchro switch that time control is carried out in transmitting-receiving in radio frequency part, therefore needs to introduce synchronous extraction module in the design of repeater.
Extract the three kinds of modes that mainly contain synchronously in the TD-SCDMA repeater.
The √ carrier wave detects
√ GPS is synchronous
The √ terminal module
The terminal module mode has following shortcoming at present:
1. terminal module is immature.
2. terminal module has the possibility that receives a plurality of sectors or other base station signal, and causes the repeater timing error.
3. terminal module sensitivity is to received signal synchronously had relatively high expectations.
And the mode precision that carrier wave detects is lower, be subject to the influence of wireless environment, so the GPS method of synchronization is widely used.
But there are the following problems in the application of repeater synchronously to adopt GPS;
1, time slot disposes automatically: in the TD-SCDMA system, can control and change the period length ratio that sends and receive flexibly, can conveniently adjust the time slot configuration number of up-downgoing, the high efficiency of transmission of non-symmetrical services such as this especially suitable from now on mobile Internet, multimedia video program request.
2, since TD-SCDMA to carry out the whole network by GPS synchronous, so the repeater can obtain the starting point of frame from the absolute time of GPS, takies number of time slots according to its protection time slot and up-downgoing then and calculates second and be up to the descending transfer point time.
3, still, be to know concrete uplink and downlink timeslot allocation ratio by the GPS method of synchronization, need can bring very big inconvenience to the construction and the maintenance of repeater like this, so the automatic configuration of time slot allocation to be very important by artificial input.
Summary of the invention
Defective or deficiency at above-mentioned existence the objective of the invention is to, and provide a kind of synchronous based on satellite, simple in structure, and be easy to use based on the synchronous radio network repeater time slot configuration device of satellite.
Another goal of the invention of the present invention provides the adjustment collocation method.
The technical solution that realizes the foregoing invention purpose is: synchronous based on satellite, simple in structure, radio network repeater automatic time-slot inking device easy to use, marked improvement of the present invention is: synchronization module and time slot detection module are embedded in the control module of repeater, the signal of the GPS module that its synchronization module is built-in inputs to the counting submodule, the signal of counting submodule inputs to the time-delay submodule, the signal of time-delay submodule inputs to the built-in time slot measuring and calculating of time slot detection module and sets submodule, and the signal of time slot Rough Inspection submodule inputs to the time slot measuring and calculating and sets submodule.
A kind of time slot of claim 1 product is adjusted collocation method automatically, and its time slot workflow of configuration automatically may further comprise the steps:
(1) when initial start, at first closes radio-frequency module, carry out the synchronous of GPS simultaneously;
(2) in case GPS is synchronous, then begin to count with the time reference of GPS, calculate all time slot proportion second transfer point information;
(3), finally provide the point second change-over time of different time-gap proportioning according to the distance setting time delay of repeater and base station;
When (4) starting shooting, the time slot detection module carries out the second time slot transfer point Rough Inspection to the downlink radio-frequency signal that receives simultaneously, and time slot state detection information compares with the time slot point second change-over time that calculates, and the actual proportioning situation that gets output time slot also is provided with.
(5), open the radio-frequency module operate as normal.
Above-mentioned submodule implementation method is specially: a GPS submodule is set, with the acquisition time benchmark.Be provided with a counting submodule, to calculate the position of conversion point of different time-gap proportioning.A time-delay submodule is set, to adjust the time delay of repeater and base station different distance.The main work of time slot detection module is exactly to carry out time slot rough detection, time slot reckoning and playback, thereby finishes the automatic configuration of time slot.
The present invention compared with prior art, solved under based on the work of TDD dual-mode, in the unfixed wireless network environment of uplink and downlink timeslot, the setting needs craft of wireless discharging-directly station time slot or the problem of setting by remote network management, realized the automatic configuration of time slot under this environment, the time slot that can detect automatically in the network is set, and has significantly reduced the cost and the error probability of repeater engineering maintenance.The invention of employing this method, it is less demanding that wireless signal is detected response speed, and the time slot that the detection speed error all can accurately be measured within time slot duration/2 in the network is set.
