Description

A kind of synchronous method, system and equipment of carrying out

Technical field

The present invention relates to wireless communication technology field, particularly a kind of synchronous method, system and equipment of carrying out.

Background technology

In recent years, along with popularizing of mobile Internet (Mobile Internet) and smart mobile phone, the mobile data traffic demand rapidly increases, and indoor data service has occupied a large portion ratio.Indoor and hot spot data service feature for the user be generally fixing perhaps very low speed move, less demanding to mobility; On the other hand, data service is mainly based on the Internet of IP (Internet Protocol, Internet Protocol) professional, and is more single to the requirement of QoS (Quality of Service, service quality), and well below the requirement of carrier class business to QoS.Traditional cell mobile communication systems mainly towards be high-speed mobile, the professional design of the carrier class of seamless switching, when it carried big flow low speed IP data packet traffic, efficient was on the low side, cost is too high.

To sum up, honeycomb mobile operator need find out low cost, and high power capacity is fit to the solution that the indoor wireless data insert.Main solution is at present:

Home eNodeB (Femto; Femtocell formula base station) as solving other a solution indoor and hot zones data service flow demand, indoor distances is shorter according to covering, the characteristics that number of users is less; Reduce the capacity requirement and the merit emissivity at single station; Usually number of users is at 8-20, and power and mobile phone terminal are suitable, generally below 23dBm.Figure 1A is LTE (Long Term Evolution, a Long Term Evolution) Femto network architecture sketch map, and the framework of employing Femto scheme can be referring to shown in Figure 1A.

The relative indoor covering system of Home eNodeB and little base station, cost is lower, dispose more flexible, the effect of business experience of having played certain indoor data.But its deficiency be not optimized to indoor data service characteristics with: Home eNodeB; With the LTE system is example; LTE Femto system has adopted the protocol infrastructure and the Interface design of LTE system complete basically; So the complicacy of realization, just base station capacity and power reduce, so cost is high always.In addition; Femto is IMT (International MobileTelecommunications; International mobile telecommunication) equipment in the system; Its frequency that can work is still authorized frequency range for the operator in the IMT, and the bandwidth that relative WiFi can use is less, can't satisfy operator's data service shunting demand fully.

At present, Home eNodeB mainly contains following three kinds of simultaneous techniquess:

1, GPS (Global Positioning Systems, global positioning system).

If HeNB has installed the GPS receiver, can obtain the gps satellite synchronizing signal, GPS just can be for it provides accurately time service (100ns) synchronously, however the use of GPS is subject to environment, especially almost can't work in indoor environment, and cost is higher.

2, IEEE (IEEE Institute of Electrical and Electronics Engineers Institute of Electrical and Electronics Engineers) 1588v2.

Under good back haul link network supports (can be the fiber optic Ethernet that operator lays); 1588v2 also can provide the synchronization accuracy of microsecond level; But high-quality back haul link support can be arranged all under not all scene; And cable and XDSL (X digital subscriber line, x Digital Subscriber Line road) also exist the time delay problem of unstable, can produce considerable influence to synchronization accuracy.

3, network monitoring.

The network monitoring scheme can be worked under the condition that GPS and 1588v2 scheme can't be used, and therefore this is a kind of requisite synchronization mechanism for TD-LTE HeNB.The network monitoring scheme refers to HeNB and from the synchronizing signal of adjacent macrocell or other HeNB sub-district, demodulates timing information.Use the HeNB sub-district of network monitoring mechanism can use the synchronizing signal or the reference signal of other eNB (eNB synchronously) sub-district.Under most scenes, the covering of macrocell is fairly perfect, all is this single-hop synchronization scenario.But when the HeNB cell detection just needs to adopt the mode of multi-hop less than the eNB cell signal time; The signal (HeNB sub-district) of synchronous other non-GNSS (Global Navigation Satellite System, GLONASS) is shown in Figure 1B; HeNB2 detects the signal less than synchronous eNB; But can detect the signal of HeNB1, so just can carry out indirect synchronization through the signal of monitoring HeNB1, wherein the HeNB1 signal of monitoring synchronous eNB sub-district carries out synchronously.

For the synchronous scene of multi-hop, need to introduce the notion of the number of plies.The synchronous number of plies of a HeNB refers to the minimum hop count between this HeNB and the GPS synchronisation source.The number of plies that the synchronous number of plies of a HeNB equals its synchronisation source adds one, and for example among Figure 1B, the number of plies of eNB is 0 synchronously, and the synchronous number of plies of HeNB1 is 1, and the synchronous number of plies of HeNB2 is 2.

The cost of existing LTE Femto is higher relatively; With wifi (Wireless Fidelity; Adopting wireless fidelity technology) compared a certain distance, therefore introduced a kind of new network access system, and added AP (Access Point in this system; Access point) equipment, but also there is not AP equipment to carry out synchronous scheme at present.
