Specific embodiment

It is existing in the prior art when the synchronizing information carried in SIB signaling changes in order to solve, other operations The base station to be synchronized of quotient is difficult to the problem of detecting this variation in time, and the embodiment of the invention provides a kind of air interface synchronization schemes. In the technical solution, network element to be synchronized is listened on the resource location of predetermined listening RS less than different operator SIB signaling is listened to when the listening RS of synchronisation source network element, obtains the synchronizing information carried in SIB signaling, and same according to this Step information is updated or reselects synchronisation source network element to the synchronizing information of itself.This method utilizes and listens to listening Whether the synchronizing information that RS is carried in the SIB signaling to judge synchronisation source network element changes, when predetermined When listening to the listening RS less than the synchronisation source network element of different operator on the resource location of listening RS, that is, illustrate The synchronizing information carried in SIB signaling is changed, thus program effective solution is existing in the prior art can not The problem of synchronizing information carried in discovery SIB signaling in time changes.

The embodiment of the present invention is illustrated below in conjunction with Figure of description, it should be understood that implementation described herein Example is merely to illustrate and explain the present invention, and is not intended to restrict the invention.And in the absence of conflict, the reality in the present invention The feature for applying example and embodiment can be combined with each other.

Assuming that the network element to be synchronized from operator A lacks absolutely timing, provided in the first frequency point f1 for user equipment (UE) Service, and the synchronisation source network element from operator B has absolutely timing, carries in the second periodic broadcast transmission of frequency point f2 The SIB signaling and listening RS of synchronizing information, wherein f1 and f2 is closer and radio frequency isolation degree is smaller.

When network element to be synchronized does not additionally configure dedicated receiving device, in order to be listened on f2 from operator B Synchronisation source network element SIB signaling or listening RS, it is necessary to interrupt from the downlink data transmission on f1.

Under this application scenarios, the embodiment of the invention provides a kind of air interface synchronization methods, as shown in Figure 1, being the party The implementation flow chart of method, the executing subject of this method are network element to be synchronized, specifically include the following steps:

Step 11, network element to be synchronized is listened on the resource location of predetermined interception reference signal listening RS Less than synchronisation source network element listening RS when, listen to the system information block SIB signaling of synchronisation source network element, obtain SIB signaling The synchronizing information of middle carrying；

Wherein, which is that network element to be synchronized is selected from least one network element of different operator；

Specifically, when network element to be synchronized is listened on the resource location of predetermined listening RS less than synchronisation source When the listening RS of network element, illustrate that the synchronizing information carried in the SIB signaling of synchronisation source network element has occurred and that change, therefore When satisfying the condition, network element to be synchronized just listens to the SIB signaling of synchronisation source network element, obtains the synchronous letter carried in SIB signaling Breath.

Wherein, the synchronizing information carried in SIB signaling can be, but not limited to include: synchronous regime (synchronization Status) information and/or synchronization levels (stratum level) information.

It should be noted that the SIB signaling mentioned in the embodiment of the present invention can refer to SIB1 signaling, can also refer to except SIB1 Other SIB signalings except signaling, are properly termed as SIB x signaling, wherein x=2, and 3,4 ....

Since the sending cycle and sub-frame offset of SIB1 signaling are fixed, and carry the resource of SIB x signaling Configuration information, so if synchronizing information is carried in SIB1 signaling, then network element to be synchronized can be according to SIB1 signaling Fixed sending cycle and sub-frame offset listens to SIB1 signaling；If synchronizing information is carried in SIB x signaling, Network element so to be synchronized then needs to get the resource allocation information of SIB x signaling from SIB1 signaling first, and then basis obtains The resource allocation information of the SIB x signaling taken, then listened on the corresponding resource location of resource allocation information of SIB x signaling SIB x signaling.

Step 12, network element to be synchronized is according to the synchronizing information carried in the SIB signaling of acquisition, to itself synchronizing information into Row updates, or reselects synchronisation source network element from least one network element of different operator.

Relative to the air interface synchronization method of network element side network element to be synchronized, the embodiment of the invention also provides a kind of synchronisation source network element side network elements Air interface synchronization method, as shown in Fig. 2, being the implementation flow chart of this method, the executing subject of this method is synchronisation source network element, tool Body includes the following steps:

Step 21, when the synchronizing information carried in the SIB signaling of synchronisation source network element changes, synchronisation source network element changes Former interception reference signal mode listening RS pattern obtains new listening RS pattern；

Wherein, synchronisation source network element changes original listening RS pattern, obtains new listening RS pattern, It can be, but not limited to following two ways to realize:

First way:

Synchronisation source network element in advance implicitly ties up the synchronizing information carried in listening RS pattern and SIB signaling It is fixed.

For example bind the stratum level information carried in listening RS pattern and SIB signaling, i.e., The stratum level information carried in listening RS pattern and SIB signaling has one-to-one relationship, such as Fig. 3 It is shown, when the stratum level information of the carrying in SIB signaling from information 1 variation be information 2 when, listening RS Also the corresponding variation of slave pattern 1 is mode 2 to pattern.

The second way:

Synchronisation source network element presets listening RS pattern candidate collection.

When the synchronizing information carried in SIB signaling changes, listening RS pattern is in the candidate collection It is middle to be reconfigured, i.e., the variation of the synchronizing information carried in listening RS pattern and SIB signaling is bound.Such as It is only 2 kinds of listening RS in pre-set listening RS pattern candidate collection shown in Fig. 4 Pattern, when changing SIB signaling, listening RS pattern is in 2 kinds of listening RS pattern In switch over, i.e., the transformation of the synchronizing information that carries in SIB signaling is primary, and listening RS pattern just switches once.

It should be noted that when listening RS pattern set in former listening RS pattern into When row reconfiguration, need to meet: reconfiguration gap should be not less than sending cycle (the i.e. listening RS of listening RS The variation of pattern can centainly embody on adjacent listening RS, to avoid network element side network element missing inspection to be synchronized).

Step 22, listening RS is transmitted at new listening RS pattern.

In the step, synchronisation source network element transmits listening RS at new listening RS pattern and includes but not It is limited to following two kinds of situations:

The first situation:

The listening RS and synchronisation source network element that synchronisation source network element is transmitted at new listening RS pattern are sent out The RS (RS that synchronisation source network element is sent to UE is known as legacy RS by the embodiment of the present invention) for giving UE is different, therefore works as Listening RS is transmitted at new listening RS pattern, and legacy RS is in former listening RS When transmitting under pattern, network element to be synchronized can accurately judge whether former listening RS pattern is used to pass Defeated listening RS, to accurately judge whether listening RS pattern is changed, i.e. synchronisation source net Whether the synchronizing information of the SIB signaling of member changes.

Second situation:

The listening RS and synchronisation source network element that synchronisation source network element is transmitted at new listening RS pattern are sent out The RS (RS that synchronisation source network element is sent to UE is known as legacy RS by the embodiment of the present invention) for giving UE is identical, therefore works as Listening RS is transmitted at new listening RS pattern, and legacy RS is in former listening RS When transmitting under pattern, since listening RS and legacy RS are identical RS, network element to be synchronized can not be identified Listening RS or the legacy RS of original listening RS pattern transmission out, therefore can not judge Whether listening RS pattern is changed.

In order to solve this problem, when utilizing first way to realize in step 21, this method can also include:

Forbid transmitting legacy RS in former listening RS pattern.

When utilizing the second way to realize in step 21, this method can also include:

Forbid transmitting on other listening RS pattern in addition to new listening RS pattern legacy RS。

For example, when listening RS is location reference signals (Position Reference Signal, PRS), it can To disable positioning positioning business in certain subframes；Or it is arranged to broadcast subframe MBSFN entirely without PRS；Or It is an only hair listening RS, does not send out legacy RS, and by listening RS pattern and frequency offset amount offset Wire Parameters；

When listening RS is public reference signal (Common Reference Signal, CRS) or channel status letter It, can be a little by certain when ceasing reference signal (Channel State Information Reference Signal, CSI-RS) Frame is configured to the MBSFN sub-frame without CRS or CSI-RS；Either only hair listening RS, does not send out legacy RS, and By listening RS pattern and frequency domain offset Wire Parameters.

Embodiment 1:

As shown in figure 5, to be disabled in the case of in step 22 the first using the legacy RS based on MBSFN sub-frame The schematic diagram of technology.Wherein, listening RS is CRS, and candidate sending mode candidate TxPattern1 is corresponding Correspond to stratum level=1, candidate in stratum level=0, candidate TxPattern2 TxPattern3 corresponds to stratum level=2.

Before the synchronizing information change carried in SIB signaling, former listening RS pattern is candidate TxPattern1；After the synchronizing information change carried in SIB signaling, new listening RS pattern is candidate TxPattern2, and the corresponding subframe of candidate TxPattern1 is then configured as MBSFN sub-frame.

Embodiment 2:

As shown in fig. 6, to be disabled under second situation in step 22 using the legacy RS based on MBSFN sub-frame The schematic diagram of technology.Wherein, listening RS is CRS, and includes: to wait in listening RS pattern candidate collection Select sending mode candidate TxPattern1, candidate TxPattern2 and candidate TxPattern3.

Before the synchronizing information change carried in SIB signaling, former listening RS pattern is candidate TxPattern1, and candidate TxPattern2 and candidate in addition to candidate TxPattern1 The corresponding subframe of TxPattern3 is both configured to MBSFN sub-frame；After the synchronizing information change carried in SIB signaling, newly Listening RS pattern is candidate TxPattern2, and in addition to candidate TxPattern2 The corresponding subframe of candidate TxPattern1 and candidate TxPattern3 is both configured to MBSFN sub-frame.

Embodiment 3:

As shown in fig. 7, to use the frequency domain based on V-shift in the first situation and second situation in step 22 The schematic diagram of offset technology.Wherein, listening RS is CRS, and candidate TxPattern1, candidate TxPattern2 and candidate TxPattern3 respectively corresponds different frequency offset amounts.

Before the synchronizing information change carried in SIB signaling, former listening RS pattern is candidate TxPattern1, corresponding frequency offset amount 1；After the synchronizing information change carried in SIB signaling, new listening RS Pattern is candidate TxPattern2, corresponding frequency offset amount 2.

Based on the introduction of the above-mentioned air interface synchronization method to network element side network element to be synchronized and synchronisation source network element side network element, below by way of specific Example, the essence for technical solution that the present invention is furture elucidated.

1, synchronisation source network element (being under the jurisdiction of the operator B with absolute timing)

(1) synchronizing information, such as synchronization status information and/or stratum are carried in SIB signaling Level information；

(2) listening RS pattern candidate collection is preset；

(3) corresponding to change listening RS when the synchronizing information carried in SIB signaling changes pattern。

2, network element (being under the jurisdiction of the operator A for lacking absolute timing) to be synchronized

Two states of network element side network element to be synchronized: init state and tracking mode are defined first.

Tracking mode is transferred to from init state: directly being jumped；

Init state is jumped to from tracking mode: conditional jump, i.e., when network element to be synchronized is in the listening determined When listened on the resource location of RS less than listening RS, init state is jumped to from tracking mode.

For init state:

(1) the SIB signaling from other operators is listened to；

(2) the listening RS pattern of other side is obtained；

If the synchronizing information carried in listening RS pattern and SIB signaling there are one-to-one relationship, Listening RS pattern is determined according to the synchronizing information carried in SIB signaling；

If listening RS pattern does not correspond to one-to-one relationship with SIB signaling, then blind examination is needed Determine listening RS pattern.

For tracking mode:

According to the listening RS pattern determined, carried out on the resource location of corresponding listening RS Synchronized tracking, wherein being required to listen to each listening RS signal.

In above-mentioned technical proposal, the SIB signaling for listening to different operator of network element trigger-type to be synchronized, i.e., only when SIB believes The synchronizing information carried in order the Shi Caihui that changes is listened to again.In this scenario, network element to be synchronized is predetermined SIB letter is listened to when listening to the listening RS less than the synchronisation source network element of different operator on the resource location of listening RS It enables, obtains the synchronizing information carried in SIB signaling, and be updated according to synchronizing information of the synchronizing information to itself.The party Method judges whether the synchronizing information carried in the SIB signaling of synchronisation source network element changes using listening RS is listened to, As the listening for listening to the synchronisation source network element less than different operator on the resource location in predetermined listening RS When RS, that is, illustrate that the synchronizing information carried in SIB signaling is changed, therefore program effective solution is in the prior art It is existing to find the problem of synchronizing information carried in SIB signaling changes in time.

Further, network element to be synchronized in the SIB signaling for listening to synchronisation source network element and obtains the synchronization carried in SIB signaling During information, in order to parse SIB signaling, the physical down control letter of subframe where needing sequentially to demodulate SIB1 and SIB x Road (Physical Downlink Control Channel, PDCCH) and Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), therefore network element to be synchronized must be listened to over multiple subframes, that is, be meaned This multiple subframe must be all silent, zone of silence include the domain PDCCH, the domain PDSCH and CRS of downlink subframe etc. with reference to letter Number.

The introduced other silent operation of full sub-frame level, which is demodulated, in order to carry out SIB x to set the user being normally carried out Standby UE is adversely affected, i.e. UE is listened in continuous multiple subframes less than signals such as PDCCH, PDSCH and CRS, or even can not It safeguards normal timing and normal wireless resource management (Radio Resource Management, RRM) survey can not be carried out Amount (such as Reference Signal Received Power (Reference Signal Receiving Power, RSRP) measurement).

Therefore timing is conciliate in the reception of SIB x signaling of the network element to be synchronized between carrying out different operator, it is necessary to pass through certain Suitable mode notifies UE, keeps the behavior of UE normally controllable.

Therefore, in order to reduce the influence to UE side business, the embodiment of the invention also provides following methods:

The first scheme:

Introduce on/off switching mechanism in the prior art.

When network element to be synchronized listened on the resource location of predetermined listening RS it is same less than different operator When the listening RS of step source network element, network element to be synchronized switches first to off state, then listens to the synchronization of other operators The SIB x signaling of source network element.

In order to listen to other operators synchronisation source network element SIB x signaling, network element to be synchronized initially enters off state (this is related to cell small cell on state to the switching flow of off state, and a series of interactive processes with UE, This partial content can refer to 3GPP standardized content, repeat no more in embodiments of the present invention).Secondly, network element to be synchronized exists The SIB x signaling of the synchronisation source network element of other operators is listened under off state.Finally, network element to be synchronized exits off state, into Enter on state, restores normal UE business.

The receiving time phase of the time duration of the off state of network element to be synchronized with SIB x signaling is required in the program Matching.

Second scheme:

Introduce measurement interval measurement GAP mechanism.

The program can include but is not limited to following two ways again:

1, the existing measurement interval measurement GAP configuration of 3GPP is adopted

(1) the first configuration method:

Network element to be synchronized according to the system information SI configuration information of synchronisation source network element, configure at least one first Measurement GAP enables network element to be synchronized in the same first Measurement GAP while receiving synchronisation source The one SIB1 signaling of system information block and SI message of network element；

The configuration information of at least one the first Measurement GAP is sent to itself corresponding UE, to notify UE to exist Listening to for the configuration information instruction of at least one the first Measurement GAP does not receive what network element to be synchronized was sent in window Data.

(2) second of configuration method:

Network element to be synchronized configures at least one second measurement interval according to the SI configuration information of synchronisation source network element Measurement GAP enables network element to be synchronized to receive synchronisation source network element in each 2nd Measurement GAP SI message；

The configuration information of at least one the 2nd Measurement GAP is sent to itself corresponding UE, to notify UE to exist Listening to for the configuration information instruction of at least one the 2nd Measurement GAP does not receive what network element to be synchronized was sent in window Data.

It should be noted that above-mentioned first Measurement GAP and the 2nd Measurement GAP is 3GPP standard In existing measurement be spaced measurement GAP, first and second are only used for distinguishing different configuration methods.

Since SI message can be transmitted in the unlimited long-time inner circumferential phase, and existing measurement GAP only maintains one The limited time (such as maximum 480ms) of section, therefore network element to be synchronized requires during listening to SIB x signaling every time Configure one or more measurement GAP.

Specifically, because SI configuration information is carried in SIB1 signaling, due to the sending cycle and son of SIB1 signaling Vertical shift is fixed, and network element to be synchronized can initialize the SIB1 signaling that synchronisation source network element can be received when starting, Therefore network element to be synchronized can obtain its SI parameter configuration (including SIB1's by the SIB1 signaling of demodulation synchronisation source network element The serial number and SI window period occurred in schedulingInfoList list), then make SI parameter configuration and The configuration parameter (including starting sub-frame offset, pattern ID) of measurement GAP matches；

Wherein matching principle can be with are as follows:

Network element to be synchronized can capture the wireless frame timing of synchronisation source network element, that is, require network element and synchronisation source net to be synchronized Member can be realized frame synchronization；

SI length of window≤measurement GAP length of window (i.e. 6ms).Therefore SI length of window can only gathered Value in { 1ms, 2ms, 5ms }.Preferred 5ms in the embodiment of the present invention.

It is described below a kind of based on the synchronisation source for adopting the existing measurement interval measurement GAP configuration mode of 3GPP The embodiment of the parameter configuration of network element and network element to be synchronized:

In this example, synchronizing information is carried in SIB x signaling (other SIB signalings in addition to SIB1 signaling).

1, the SI configuration of synchronisation source network element side network element:

SI message bearing SIB x signaling is configured, and carries the synchronizing information between different operator in SIB x signaling, such as Synchronous status and stratum level；

SI length of window y1ms, the y1 value in set { 1,2,5 } are configured in SIB1.Preferred y1 in the embodiment of the present invention =5；

If the window period of serial number n, SI that SI occurs in the schedulingInfoList list of SIB1 be 80 × Y2ms, value the y2 value in set { 1,2,4,8,16,32,64 }.In general, for air interface synchronization purpose, y2 should Take biggish numerical value.

From above-mentioned configuration, it can be seen that when the beginning frame number of SI message is SFN0, starting subframe number is subSFN0, Then

SFN0=FLOOR ((n-1) * y1/10) mod (80*y2)

SubSFN0=(n-1) * y1mod10

For the first above-mentioned configuration mode: network element to be synchronized connects simultaneously in the same first measurement GAP SIB1 the and SI message of Shou Yi operator needs to constrain the value range of n, so that SI message and SIB1 message at least exist It is adjacent in one or more subframes.

For example, set y1=5, then require n=1 or 2 or 5 or 6 or 9 or 10 or ...

For above-mentioned second of configuration mode: network element to be synchronized can choose at random the value of n and y2.

2, the measurement GAP configuration of network element side network element to be synchronized

(1) by configuring the starting sub-frame offset parameter of measurement GAP, so that measurement GAP Initial frame number SFN0 and starting subframe number are that subSFN0 and SI m message matches.

For the first above-mentioned configuration method: network element to be synchronized receives different simultaneously in the same measurement GAP SIB1 the and SI message of operator, it is desirable that the SFN0=0mod80ms of measurement GAP, subSFN0=0 (correspond to SIB1's first appears subframe)；

For above-mentioned second of configuration method: network element to be synchronized demodulates SIB1 first, therefrom acquisition SI configuration information, and according to The parameter of this configuration measurement GAP；

(2) configuration measurement interval mode identifies measurement GAP Pattern ID.In the embodiment of the present invention preferably Measurement GAP Pattern ID=2.

(3) it is directed to each SI message, configures one or more measurement GAP, as needed to guarantee SI message Reliable reception and demodulation.

The first more above-mentioned configuration method and second of configuration method, the main distinction are that the former is same SIB1 the and SI message of different operator is received in measurement GAP simultaneously；And the latter only needs in a measurement SI message is detected in GAP.

Therefore the first above-mentioned configuration method and second of configuration mode are similar in configuration method, and only the first is configured Mode is some more to the configuration constraint condition of SI pattern.

2, design listen to the longer measurement GAP of window (be different from existing measurement GAP, in order to It is distinguish, the measurement GAP configured in this method is the 3rd measurement GAP).

At least one the 3rd measurement GAP of network element configuration to be synchronized, the 3rd measurement of wherein at least one The window of listening to of GAP enables network element to be synchronized to receive synchronisation source net in each 3rd Measurement GAP greater than 6ms The one SIB1 signaling of SI message and/or system information block of member；

The configuration information of at least one the 3rd measurement GAP is sent to itself corresponding UE, to notify UE to exist The listening to for configuration information instruction of at least one the 3rd measurement GAP cannot be in all subframes of former frequency point in window All receive the data that network element to be synchronized is sent.

Specifically, network element to be synchronized does not need to know the SI pattern configuration of synchronisation source network element side network element, and separate configurations are detectd The longer 3rd measurement GAP of window is listened, and the 3rd measurement GAP is notified to UE.Network element to be synchronized Downlink measuring signal (such as CRS) is sent in the part subframe in the 3rd measurement GAP.And UE receives third After the configuration information of measurement GAP, do not expect to hear RS signal in all subframes of former frequency point, but in order to Maintenance is synchronous and measurement, and UE will attempt during this period of time to go to listen to the RS signal of network element to be synchronized, and sends RS at these Synchronous maintenance and RRM measurement are executed in the subframe of signal.

A kind of reality of the parameter configuration of mode that the longer measurement GAP of window is listened to based on design is described below Apply example.Synchronizing information is carried in SIB x signaling (other SIB signalings in addition to SIB1 signaling) in the present embodiment.

1, network element side network element to be synchronized:

Network element to be synchronized does not need to know that synchronisation source network element side network element SI pattern is configured, and to listen to window longer for separate configurations The 3rd measurement GAP, and the configuration information of the 3rd measurement GAP is notified to UE.

Network element to be synchronized demodulates the SIB1 signaling of other operators, Cong Zhongzhi in the 3rd measurement GAP first Certainly it can't hear SIB x signaling in which subframe of road, then send the RS signals such as CRS in these subframes.For example, network element to be synchronized These can be can't hear certainly the sub-frame configuration of SIB x signaling at almost blank subframe (Almost Blank Subframe, ABS)。

2, the side UE

After UE receives the configuration information of the 3rd measurement GAP, not expecting can in all subframes of former frequency point Hear CRS signal.But in order to safeguard synchronous and measurement, UE will attempt during this period of time to go to listen to the CRS of network element to be synchronized Signal, and synchronous maintenance and RRM measurement are executed in the subframe that these send CRS signal.

Other than the SIB signaling for listening to different operator of the network element trigger-type to be synchronized of above-mentioned introduction, the present invention is implemented Example additionally provides a kind of air interface synchronization method, as shown in figure 8, being the implementation flow chart of this method, executing subject is to be synchronized Network element, this method include the following steps:

Step 81, network element to be synchronized listens to the system information block SIB letter of synchronisation source network element according to the pre-set period It enables, obtains the synchronizing information of the synchronisation source network element carried in SIB signaling；

Wherein, synchronisation source network element is that network element to be synchronized is selected from least one network element of different operator；

Step 82, according to the synchronizing information carried in SIB signaling, the synchronizing information of itself is updated, or from different Synchronisation source network element is reselected at least one network element of operator.

Further, network element to be synchronized in the SIB signaling for listening to synchronisation source network element and obtains the synchronization carried in SIB signaling During information, equally exist the problem of how reducing the influence to UE side business, in the embodiment of the present invention can with but not It is limited to " introducing on/off switching mechanism in the prior art " using above-mentioned introduction and " introduces measurement interval Measurement GAP mechanism " both methods reduces the purpose of the influence to UE side business to realize.Specific implementation method It has been described in detail in the above-described embodiments, details are not described herein.

Two examples are named the present embodiment is described in detail.It is to carry synchronizing information in following two examples In SIB x signaling (other SIB signalings in addition to SIB1 signaling).

Embodiment 1:

When using on/off switching mechanism in the prior art is introduced, the basic procedure of this method is as follows:

1, synchronisation source network element (being under the jurisdiction of the operator B with absolute timing)

Synchronizing information, such as synchronization status information and/or stratum are carried in SIB signaling Level information；

2, network element (being under the jurisdiction of the operator A for lacking absolute timing) to be synchronized

For initial phase:

Blind examination SIB1 after network element starting to be synchronized, obtains the resource allocation information of the SIB x signaling of synchronisation source network element；

Network element to be synchronized configures on/off switch week according to the resource allocation information of the SIB x signaling of synchronisation source network element The time duration of phase and off state；

Specifically, the step can be, but not limited to realize using following methods: network element to be synchronized is according to synchronisation source network element The resource allocation information of SIB x signaling, first configuration SIB signaling receive window, including listening periods, offset and measurement window Length etc.；Then long further according to the duration in SIB signaling reception window configuration on/off switch period and off state Degree, the off state duration need to receive window comprising SIB x signaling.

It should be noted that SIB signaling, which receives window, does not need notice UE, and received in window in SIB signaling, it is desirable that energy Enough while listening to SIB1 signaling and SI message.

For tracking mode:

Step 1: network element to be synchronized initially enters off state；

Step 2: network element to be synchronized periodically receives detection SIB1 signaling and carrying synchronizing information in window in SIB signaling SIB x signaling, and the synchronizing information of the SIB x signaling bear according to detection updates the synchronizing information of itself；

In this process, network element to be synchronized if it find that the SIB x signaling that SIB1 signaling is carried resource allocation information Change, then then need to reconfigure SIB signaling receive window and on/off handoff parameter (on/off switching cycle, And the time duration of off state).

Step 3: network element to be synchronized exits off state, is switched on state, restores UE business.

Embodiment 2:

It is spaced when using the existing measurement of 3GPP of continuing to use being introduced into the measurement GAP mechanism of measurement interval When second of configuration method of measurement GAP configuration, the basic procedure of this method is as follows:

1, synchronisation source network element (being under the jurisdiction of the operator B with absolute timing)

Synchronizing information, such as synchronization status information and/or stratum are carried in SIB x signaling Level information；

(go out in the schedulingInfoList list including SIB1 to carry the SI message arrangement parameter of SIB x signaling Existing serial number and SI window period).

2, network element (being under the jurisdiction of the operator A for lacking absolute timing) to be synchronized

For initial phase:

Network element blind examination SIB1 to be synchronized obtains the resource allocation information of the SIB x signaling of synchronisation source network element.

For tracking mode:

Step 1: network element to be synchronized is periodically configured according to the resource allocation information of the SIB x signaling of synchronisation source network element Multiple 2nd measurement GAP are simultaneously notified to UE；

Step 2: network element to be synchronized detects the SIB x signaling of synchronisation source network element in the 2nd measurement GAP, and According to the synchronizing information of the SIB signaling bear of detection, the synchronizing information of itself is updated.

In addition, it should also be noted that, the whether method of the SIB x signaling for listening to different operator of above-mentioned trigger-type, Still the method for periodically listening to the SIB x signaling of different operator, involved network element to be synchronized all can be: belonging to it Operation quotient variety at least one base station eNB.

Specifically, the cluster cluster of the operator belonging to network element to be synchronized just starts deployment phase, can permit all Or partial (such as by randomly selecting) eNB actively listen to other operators air interface synchronization signal (including SIB signaling with listening RS).Then, entire cluster carries out internal communication, chooses 1 or a few eNB specially to go to listen to come from The air interface synchronization signal of different operator；And for other not selected eNB, between different operator air interface synchronization technology then with Be in operation afterwards it is transparent, not selected eNB can by listen to the eNB chosen carry out operator in synchronization.Most Afterwards, be responsible for safeguarding air interface synchronization between different operator for selected 1 or a few eNB, including SIB signaling receive demodulation and Listening RS signal listen to and synchronized tracking.

Therefore for those not selected eNB, between different operator air interface synchronization operation only entire cluster just It is influenced when deployment, and on normal UE business entirely without influence after network normal operation.

Approach presented above is realized in the case where network element to be synchronized does not additionally configure dedicated receiving device. If dedicated receiving device can additionally be configured for network element to be synchronized, enable the receiving device and network element to be synchronized mutual at work It does not influence, the air interface synchronization of Ze Yi operator implements simpler.

Based on the thinking, the embodiment of the invention provides a kind of air interface synchronization systems, as shown in figure 9, being the reality of the system Existing schematic diagram, the system include work in the network element to be synchronized 91 of the first frequency point and work in the receiving device 92 of the second frequency point, Wherein:

Receiving device 91 obtains institute for listening to the SIB signaling of the synchronisation source network element from different operator in the second frequency point The synchronizing information carried in SIB signaling is stated, and operation is synchronized to the network element 91 to be synchronized according to the synchronizing information.

Specifically, the receiving device 92 work different operator synchronisation source network element the second frequency point f2, it is desirable that with to Synchronous network element 91 has enough radio frequency isolation degree, i.e., should when network element 91 to be synchronized is when the first frequency point f1 sends downlink data Receiving device 92 can normally receive data in f2.It, can be continually since the receiving device 92 will not influence UE business The SIB signaling of synchronisation source network element is listened to find the situation of change of the synchronizing information carried on SIB in time.
