Description

A kind ofly carry out synchronous method, system and equipment

Technical field

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

Background technology

In recent years, universal along with mobile Internet (Mobile Internet) and smart mobile phone, Mobile data traffic demand rapidly increases, and house data business occupies a large portion ratio.Indoor and hot spot data service feature are generally fixing for user or very low speed moves, less demanding to mobility; On the other hand, data service is mainly the Internet business based on IP (Internet Protocol, Internet Protocol), to QoS (Quality of Service, service quality) requirement more single, and well below the requirement of carrier class business to QoS.Traditional cell mobile communication systems mainly towards be high-speed mobile, the carrier class service design of seamless switching, when its carrying large discharge low speed IP data packet traffic time, efficiency is on the low side, high cost.

To sum up, honeycomb mobile operator needs to find out low cost, high power capacity, is applicable to the solution of indoor wireless data access.Solution main is at present:

Home eNodeB (Femto, femtocell base station) as another solution solving indoor and hot zones data service flow demand, shorter according to covering indoor distances, the feature that number of users is less, reduce capacity requirement and the merit emissivity at single station, usual number of users is at 8-20, and power is suitable with mobile phone terminal, generally at below 23dBm.Figure 1A is LTE (Long Term Evolution, Long Term Evolution) Femto network architecture schematic diagram, and the framework of employing Femto scheme can see shown in Figure 1A.

Home eNodeB is relative to indoor covering system and micro-base station, and cost is lower, disposes more flexible, serves the effect of business experience of certain house data.But its deficiency with: Home eNodeB is not optimized for house data business characteristic, for LTE system, LTE Femto system have employed the complete protocol infrastructure of LTE system and Interface design substantially, so realize complicated, just Base Station Compatibility and power reduction, so cost remains high always.In addition, Femto is IMT (International MobileTelecommunications, international mobile telecommunication) equipment in system, its frequency that can work is still for frequency range is authorized by the operator in IMT, relative WiFi can bandwidth less, carrier data service distributing demand cannot be met completely.

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

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

If HeNB has installed GPS, can obtain gps satellite synchronizing signal, GPS just can provide sync identification (100ns) accurately for it, but the use of GPS is limited to environment, especially almost cannot 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 support (can be the fiber optic Ethernet that operator lays), 1588v2 also can provide the synchronization accuracy of Microsecond grade, but all can there is high-quality back haul link support under not all scene, and cable and XDSL (X digital subscriber line, x Digital Subscriber Line road) also all there is the problem of time delay instability, considerable influence can be produced to synchronization accuracy.

3, network monitoring.

Work under the condition that network monitoring scheme cannot be able to use in GPS and 1588v2 scheme, therefore for TD-LTE HeNB, this is a kind of requisite synchronization mechanism.Network monitoring scheme refers to HeNB and demodulate timing information from the synchronizing signal of adjacent macrocell or other HeNB cell.Use the HeNB cell of network monitoring mechanism can use synchronizing signal or the reference signal of other eNB (synchronous eNB) community.Under most scene, the covering of macrocell is fairly perfect, is all this single hop synchronization situation.But when HeNB cell can't detect eNB cell signal time, just need the mode adopting multi-hop, synchronous other non-GNSS (Global Navigation Satellite System, GLONASS (Global Navigation Satellite System)) signal (HeNB cell), as shown in Figure 1B, HeNB2 can't detect the signal of synchronous eNB, but the signal of HeNB1 can be detected, so just can carry out indirect synchronization by monitoring the signal of HeNB1, the signal that wherein HeNB1 monitors synchronous eNB community carries out synchronously.

For the scene that multi-hop is synchronous, need the concept introducing the number of plies.The synchronous number of plies of a HeNB refers to the minimum hop count between this HeNB and GPS synchronisation source.The number of plies that the synchronous number of plies of a HeNB equals its synchronisation source adds one, and such as, in Figure 1B, the synchronous number of plies of the number of plies of synchronous eNB to be the synchronous number of plies of 0, HeNB1 be 1, HeNB2 is 2.

The cost of existing LTE Femto is relatively high, with wifi (Wireless Fidelity, adopting wireless fidelity technology) compare a certain distance, therefore a kind of new network access system is introduced, and add AP (Access Point in this system, access point) equipment, but also do not have AP equipment to carry out synchronous scheme at present.

One AP equipment 10 chooses the 2nd AP equipment (signal quality value of the 2nd AP equipment can be obtained by RF search) that signal quality value is greater than threshold value from all 2nd AP equipment; The 2nd AP equipment being in synchronous regime is picked out from the 2nd AP equipment chosen; From the 2nd AP equipment picked out, select the synchronous number of plies to meet synchronous the 2nd AP equipment required; From the 2nd AP equipment selected, determine that a 2nd AP equipment is as synchronisation source.

Such as synchronous requirement needs to ensure that the number of plies can not be greater than 3, then from the 2nd AP equipment picked out, select the synchronous number of plies to be not more than the 2nd AP equipment of 3.The concrete number of plies can as required or high level arrange.

Further, if the parameter information of the 2nd AP equipment also comprises the Synchronization Source of the 2nd AP equipment;

One AP equipment determines a 2nd AP equipment as synchronisation source specifically from meeting synchronous the 2nd AP equipment required:

If the Synchronization Source meeting the synchronous all 2nd AP equipment required corresponding selected is identical, an AP equipment determines that a 2nd AP equipment is as synchronisation source from the 2nd AP equipment selected;

If the Synchronization Source part that all 2nd AP equipment meeting synchronous requirement selected are corresponding is identical or complete not identical, 2nd AP equipment of identical working frequency points in the 2nd AP equipment selected divides in a set by the one AP equipment, measure the signal value of each 2nd AP equipment in each set, the set all signal values being all less than signal threshold value, as the first set, is not less than the set of signal threshold value as the second set using only having a signal value; From the first set, select a 2nd AP equipment to be not less than the 2nd AP equipment corresponding to signal threshold value as synchronisation source as synchronisation source or using signal value in the second set.

Further, if do not have the first set and the second set, an AP equipment 10 selects other frequencies as working frequency points, and initiates the request as synchronisation source to gateway device; After determining gateway device mandate, carry out network configuration, and send the parameter information of an AP equipment as synchronisation source to gateway device 20.

Here network configuration is identical with the network configuration that an above-described AP equipment carries out as synchronisation source, does not repeat them here.

Preferably, an AP equipment 10 can be selected to exist in available frequency not by the frequency of other AP hold facilities (because the AP equipment shutdown likely had, so likely occur not by the frequency of other AP hold facilities); If there is no this frequency, the signal strength signal intensity of the 2nd all AP equipment can also be selected lower than the frequency of the intensity threshold preset.

Selection rule is above pre-configured in AP equipment, preferably, can also notify what selection rule an AP equipment 10 adopts as required by gateway device 20.Accordingly, an AP equipment 10, when needing the 2nd AP equipment chosen as synchronisation source, needs the selection rule whether receiving gateway device 20 under first judging, if do not received, then chooses according to above-described mode; If receive the selection rule of gateway device 20, then according to the selection rule received and parameter information, from the 2nd AP equipment, determine that a 2nd AP equipment is as synchronisation source.

Preferably, an AP equipment 10 can also be measured each 2nd AP equipment after determining each the 2nd adjacent AP equipment, and sends measurement result to gateway device 20, for gateway device 20 reference.

Because network condition is in real-time change, the AP equipment shutdown etc. that such as new AP equipment adds or has, in order to ensure the performance of AP equipment, preferably can carry out renewal rewards theory.

Concrete, an AP equipment 10 and synchronisation source carry out the parameter information (such as cyclic polling) that synchronous backward gateway device 20 inquires about current each the 2nd adjacent AP equipment; According to the parameter information of the 2nd AP equipment of inquiry, after determining to need to upgrade synchronisation source, the parameter information according to inquiry determines that from the 2nd AP equipment a 2nd AP equipment is as synchronisation source; One AP equipment 10 carries out synchronous with synchronisation source.If reselected synchronisation source, the parameter information of self has likely changed, such as the number of plies.Preferably, after synchronisation source changes, again can send the parameter information of self to gateway device 20.

One AP equipment 10 is determined to need to upgrade a lot of because have of synchronisation source, and the such as number of plies is lower, signal quality is better.Can upgrade when meeting some factors, also can upgrade when all factors all meet.

If there is abnormal conditions, a such as AP equipment 10 disconnects being connected with synchronisation source, then an AP equipment 10 can reappear according to selection rule above and choose a 2nd AP equipment as synchronisation source.But extreme situation is an AP equipment 10 to be disconnected being connected with synchronisation source, and do not have other second equipment can as synchronisation source.In order to address this is that, preferably, an AP equipment 10 initiatively applies for synchronisation source.

Concrete, an AP equipment 10 disconnects being connected with synchronisation source, and does not have other second equipment as after synchronisation source, can initiate the request as synchronisation source to gateway device 20; One AP equipment 10, after determining that gateway device 20 is authorized, sends the parameter information of an AP equipment as synchronisation source to gateway device.

Initiate as at least one included but not limited in the request of synchronisation source in following message:

The working frequency points information of other adjacent AP equipment that the one AP equipment can search and PCI information;
