Description
Technical field
The present invention relates to communication field, relate in particular to method for synchronous, system and the equipment of a kind of Home eNodeB HeNB.
Background technology
In mobile communications network, along with the requirement to data speed and covering of growing communication, traditional provides the method for access can not meet the demands with macro base station.At present, adopt cell splitting and in hot zones or some lower powered base stations of indoor deployment such as Home (Home eNodeB), Pico (small base station), Femto (femto cell), Relay (relay station) etc. can be good at addressing this problem.These lower powered base stations are applicable under family's indoor environment, working environment or other the little overlay environment, can make operator provide and have more high data rate and more professional.
To TDD (Time Division Duplexing, time division duplex) system, how to guarantee being an important problem synchronously between the HeNB (Home eNodeB, Home eNodeB).The high precision synchronous scheme can guarantee the stabilizing effective operation of communication system, can also reduce the interference to existing macro base station.HeNB needs to register after start and synchronous process, and keeps synchronously, could provide service smoothly for user terminal.So on the basis of multilayer (multi-hop) synchronization scenario, hope can be kept under the prerequisite that guarantees synchronization accuracy synchronously as much as possible, shortens the out of alignment time of HeNB.
For HeNB synchronously, put forward following several method in the prior art:
(1) user terminal assist in synchronization: in this method, user terminal is especially at the user terminal of overlapping region, carrying out frequent measurement and information reports, keep between the base station synchronously, this scheme can realize distributed control, but the power consumption of the signaling consumption of network and user terminal all can be very big, and efficient is lower.
(2) GPS (Global Positioning System, global positioning system) is synchronous: in this method, by GPS set up between the base station synchronously, be the most frequently used method that keeps synchronous between the macro base station at present, synchronous precision is very high.Its shortcoming is: be subjected to the influence of satellite-signal power, weather and landform synchronously easily, and need equipment GPS receiver, realize that cost is higher, be not suitable for home base station network.
(3) synchronization among base stations: in this method, by the monitoring mechanism between the base station realize mutual synchronously, be that certain base station can keep synchronous by the monitoring another one CRS of synchronising base station (CommonReference Signal, public reference signal) signal.For Home eNodeB, Home eNodeB can be undertaken synchronously by the signal of macro base station around monitoring, if there is not adjacent macro base station, the signal of other synchronous Home eNodeB carries out synchronously around can monitoring, and is a kind of synchronization mechanism of layering.
At present, the scheme of above-mentioned synchronization among base stations is extensively approved at present, also is only relatively a kind of synchronization scenario concerning Home eNodeB.Consider the influence of factors such as communication environments, network topology,, can utilize the method for synchronous of multilayer (multi-hop) for the Home eNodeB that can't directly receive the macro base station signal.With networking structure shown in Figure 1 is example, and HeNB1 is synchronous with macro base station, and HeNB2 can be undertaken by HeNB1 synchronously.Defining Sync eNB among Fig. 1 (target BS synchronously) is layer 0, and the base station of utilization layer 0 is carried out synchronous base station and is layer 1 (HeNB1), and the base station of utilization layer 1 is carried out synchronous base station and is layer 2 (HeNB2), and the like.
The base station of each layer need send the information about layer, and at present, whether synchronous with eNB the base station will send the number of plies (2 bit) of this base station and information (1 bit).These information can: transmit in the MIB (MasterInformation Block, host system message block); Perhaps in SIB1 (System InformationBlock, system information block 1), transmit; Perhaps giving the subframe transmission of one deck base station configuration MBSFN (MulticastBroadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) subframe to monitor synchronously down.Simultaneously, webmaster issues the configuration about the synchronous subframe of each layer.For fear of the influence for user terminal, these synchronous subframes realize by the mode of configuration MBSFN.
HeNB registers earlier after start, adjacent signal of base station around searching for then, system information by reading adjacent base station on every side or monitor layer information (2bit) and the synchronizing information (1bit) that the MBSFN subframe is obtained respective base station, according to around the layer information of all adjacent base stations, HeNB can select a minimum base station of the number of plies to carry out synchronously as the object synchronization base station.
Problems of the prior art are: for monitoring the synchronous scheme that realizes between the base station mutually, HeNB need be after the layer information of obtaining each adjacent base station one by one and synchronizing information, by relatively obtaining the minimum adjacent base station of the number of plies (number of plies=N), and carry out with it synchronously, this moment this base station number of plies=N+1.Be used to keep this synchronous base station signal if has lost the base station, can not continue synchronously to keep, then need to upgrade synchronising base station.In view of network environment becomes increasingly complex, if the adjacent area quantity of HeNB is more, the existing synchronizing information that travels through adjacent base station by eating dishes without rice or wine can expend a large amount of time and electric weight, causes the HeNB out of alignment time long, has a strong impact on user's impression.
