Description

Method and device for obtaining neighbor discovery signal measurement time configuration DMTC (direct current transmission timing) information

Technical Field

The invention relates to the technical field of communication, in particular to a method and a device for acquiring DMTC (distributed data center) information configured by measuring time of a discovery signal of a neighboring cell.

Background

MulteFire is a radio access technology that extends Long Term Evolution (LTE) to unlicensed bands, and can operate independently in unlicensed spectrum without the help of licensed band carriers. In order to fairly occupy the unlicensed band channel and avoid mutual interference between unlicensed band devices and other devices in the unlicensed band (e.g., WiFi devices), the MF physical layer introduces a Listen Before Talk (LBT) mechanism similar to the Wireless Fidelity (WiFi) carrier sensing technology. When the base station or the terminal monitors that the unlicensed frequency band channel is occupied, namely LBT fails, the signal is stopped being sent, and when the channel is monitored to be idle, namely LBT succeeds, the signal is sent.

In order to improve the transmission efficiency of downlink common control signals of a base station under an LBT mechanism, MulteFire introduces a Discovery Reference Signal (DRS), where the DRS includes main downlink common control signals, including System broadcast, Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), enhanced Primary synchronization Signal (ePSS), enhanced Secondary synchronization Signal (eSSS), enhanced Secondary synchronization Signal (Cell), Cell Reference Signal (CRS), Primary System Information Block (MIB, Master Block), and enhanced System Information Block (SIB-MF, System Information Block), and the DRS occupies 12 or 14 symbols (Symbol) in one downlink subframe. A terminal (UE) may receive a DRS for downlink synchronization, receive an MIB and an SIB-MF within a Discovery signal measurement Configuration (DMTC) window. The MF cell only transmits the CRS in a DRS subframe or other subframes transmitted by a Physical Downlink Shared Channel (PDSCH), so that the UE can perform channel measurement on the MF serving cell or the MF neighbor cell only within the DMTC window for cell selection, cell reselection, or handover. If the base station does not know the DMTC parameters of the MF neighbor cell, the base station cannot indicate the DMTC window position of the MF neighbor cell to the UE, and the UE may perform DRS signal quality measurement on the MF neighbor cell at any time. In the existing LTE technology, a base station may obtain information of a cell of an adjacent base station through an X2 establishment procedure with the adjacent base station, but if there is no X2 interface between the base station and a base station to which the adjacent cell belongs, DMTC information of the adjacent cell cannot be obtained, and therefore, a UE served by the base station cannot perform DRS signal quality measurement in a DMTC window of the adjacent cell, which results in an increase in power consumption of the UE.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the Multefire system, a base station may send DMTC information of a local cell, a co-frequency neighboring cell and a co-frequency neighboring cell to a UE, respectively, broadcast the DMTC information of a current MF serving cell through SIB-MF, send the DMTC information of the co-frequency neighboring cell through SIB3 broadcast or through UE dedicated Radio Resource Control (RRC) message, and send the DMTC information of the co-frequency neighboring cell of a designated frequency point through SIB5 broadcast or through UE dedicated measurement configuration RRC message, so that the UE knows DRS sending time windows of the local cell (the resident or connected cell), the co-frequency neighboring cell and the co-frequency neighboring cell according to the DMTC information to perform channel measurement. The cell DMTC information comprises DMTC parameters, and the DMTC parameters comprise: DMTC window duration (DMTC-duration), DMTC window period (DMTC-Periodicity) and subframe Offset (DMTC-Offset), where DMTC-Periodicity is 40ms, 80ms or 160ms and DMTC-Offset is 0 to 159.

The UE may determine the DMTC window position of the cell according to the DMTC information of the cell by using the following formula, so as to perform channel measurement on the cell in the DMTC window.

DMTC start frame number mod T ═ FLOOR (DMTC-Offset/10);

DMTC starting subframe number DMTC-Offset mod 10;

T＝dmtc-Periodicity/10。

the DMTC information of the neighboring cell includes a synchronous identifier, which indicates that the neighboring cell of the local cell includes a cell asynchronous with the local cell when the synchronous identifier is asynchronous, and the DMTC information of the neighboring cell may further include a DMTC parameter of a neighboring cell synchronous with the local cell and/or a DMTC parameter of a neighboring cell asynchronous with the local cell.

The invention aims to solve the problem that in the prior art, a terminal cannot perform DRS signal quality measurement in a DMTC window of an adjacent cell, so that UE (user equipment) can perform DRS signal quality measurement on an MF adjacent cell at any time and the power consumption of the UE is increased. The following embodiments of the present invention provide a method and an apparatus for obtaining neighbor cell discovery signal measurement time configuration DMTC information, where DMTC information of a first cell (where the first cell is a neighbor cell of a serving cell of a second base station) sent by a second base station through neighbor cell information of the second base station is received, and DMTC information of a same-frequency neighbor cell and/or a different-frequency neighbor cell of the first base station cell is sent to a terminal according to the received DMTC information of the first cell, so that the terminal can perform DRS signal quality measurement in a DMTC window of the neighbor cell, thereby achieving an effect of reducing power consumption of the terminal.

First embodiment

As shown in fig. 1, a first embodiment of the present invention provides a method for acquiring DMTC information configured by measuring time of a discovery signal of a neighboring cell, where the method is applied to a first base station, and the method includes:

step 101, obtaining DMTC information of the first cell sent by the second base station through the neighboring cell information of the second base station.

The first cell is a neighboring cell of a serving cell of the second base station, the second base station may be a neighboring base station of the first base station or may not be a neighboring base station of the first base station, and both the first base station and the second base station may be an MF base station, an LTE base station, a Wideband Code Division Multiple Access (WCDMA) base station, a time division-synchronous code division multiple access (TD-SCDMA) base station, or a global system for mobile communications (GSM) base station.

And in the first embodiment of the present invention, the DMTC information of the first cell transmitted by the second base station may be acquired (i.e., received) according to the X2 interface message or the S1 interface message. The DMTC information of the first cell is recorded in the neighbor cell information of the second base station of the X2 interface message or the S1 interface message. It should be noted that, in order to facilitate the first base station to identify the first cell, the X2 interface message and the S1 interface message each include a network identity (NHN-ID) and a cell global identifier (ECGI) of the first cell.

And step 102, storing the acquired DMTC information of the first cell in the neighbor cell information of the second base station.

The acquired DMTC information of the first cell comprises first DMTC information and/or second DMTC information. The first DMTC information is local cell DMTC information of the first cell, and the second DMTC information is same-frequency adjacent cell DMTC information and/or different-frequency adjacent cell DMTC information of the first cell.

Specifically, the DMTC information of the local cell of the first cell includes a DMTC parameter of the local cell of the first cell, and the DMTC parameter of the local cell of the first cell specifically includes: DMTC window duration (DMTC-duration), DMTC window period (DMTC-Periodicity), and subframe Offset (DMTC-Offset). The second DMTC information is the same-frequency neighbor cell DMTC information broadcast by the first cell in the system information SIB3 and/or one or more different-frequency neighbor cell DMTC information broadcast in the system broadcast SIB 5. The DMTC information of the co-frequency adjacent cell or the inter-frequency adjacent cell comprises a synchronous identifier, when the synchronous identifier is asynchronous, the DMTC information of the co-frequency adjacent cell or the inter-frequency adjacent cell of the first cell is indicated to comprise a cell asynchronous with the first cell, and the DMTC information of the co-frequency adjacent cell or the inter-frequency adjacent cell of the first cell further comprises DMTC parameters of adjacent cells synchronous with the first cell and/or DMTC parameters of adjacent cells asynchronous with the first cell. The DMTC parameter of the synchronous neighbor cell or the DMTC parameter of the asynchronous neighbor cell includes one or more of a DMTC window duration (DMTC-duration), a period of a DMTC window (DMTC-Periodicity), and a subframe Offset (DMTC-Offset).

It can be seen that, under the condition that there is no direct communication interface between the first base station and the base station to which the first cell belongs, the first base station may still obtain the DMTC information of the first cell from the neighboring cell information sent by the second base station, so that the first base station can send the same-frequency neighboring cell DMTC information and/or different-frequency neighboring cell DMTC information of the first base station cell to the terminal according to the stored DMTC information of the first cell, thereby achieving the effect of enabling the terminal to perform DRS signal quality measurement in the neighboring cell DMTC window, and reducing the power consumption of the terminal.

Further, in the first embodiment of the present invention, a specific implementation manner of the step 102 includes the following steps: detecting whether the acquired DMTC information of the first cell contains subframe offset or not, wherein if the acquired DMTC information of the first cell contains the subframe offset, converting the subframe offset of the acquired DMTC information of the first cell into subframe offset of a DMTC window at the subframe timing of the first base station to obtain the DMTC information of the first cell after subframe offset conversion, and storing the DMTC information of the first cell after the subframe offset conversion in the adjacent cell information of the second base station; in a specific implementation, the first base station may acquire subframe timing of the first cell by monitoring a downlink synchronization signal of the first cell, so as to convert a subframe offset of the received DMTC information of the first cell into a subframe offset at the subframe timing of the first base station, where the first cell is synchronous or asynchronous with the first base station.

Another specific implementation manner of the step 102 includes: determining whether the first cell is asynchronous with the first base station; if the first cell is asynchronous with the first base station, the DMTC information of the first cell not including the subframe offset (i.e., except the subframe offset) is stored in the neighbor cell information of the second base station. The method for the first base station to determine whether the first cell is asynchronous comprises the following steps: if the received DMTC information of the first cell does not contain subframe offset, determining that the first cell is asynchronous with the first base station; or the first base station determines that the first cell is asynchronous with the first base station according to the synchronization information about the first cell configured by the OAM; alternatively, the first base station determines that the first cell is asynchronous with the first base station by querying the base station to which the first cell belongs for synchronization information. For example, the first base station may query synchronization information of a base station to which the first cell belongs through a base station Configuration Transfer (eNB Configuration Transfer) message of the S1 interface, where the first base station sets a SON information request field of the eNB Configuration Transfer to a Time synchronization information (Time synchronization Info) enumeration value; and the base station to which the first cell belongs sends an S1 message eNB Configuration Transfer containing synchronization information to the first base station after receiving the message to indicate whether the base station is asynchronous with the first base station. Further, if the first base station determines that the first cell is synchronized with the first base station, the first base station may convert the subframe offset of the received DMTC information of the first cell into the subframe offset of the DMTC window at the subframe timing of the first base station to obtain the DMTC information of the first cell after the subframe offset conversion, and store the DMTC information of the first cell after the subframe offset conversion in the neighboring cell information of the second base station.

It should be noted that, when the received DMTC information of the first cell includes a subframe offset, whether to convert the subframe offset of the received DMTC information of the first cell mainly depends on whether the subframe offset of the received DMTC information of the first cell has been converted. Specifically, if the subframe offset has been converted when the second base station sends the DMTC information of the first cell, the first base station does not need to convert the subframe offset when receiving the DMTC information of the first cell, and directly stores the received DMTC information of the first cell in the neighboring cell information of the second base station; if the second base station does not convert the subframe offset when sending the DMTC information of the first cell, the first base station needs to convert the subframe offset when receiving the DMTC information of the first cell, and after the conversion, the DMTC information of the first cell after the subframe offset conversion processing is stored in the neighboring cell information of the second base station.

Here, the above procedure of the first base station converting the subframe offset of the received DMTC information of the first cell is further described with a specific example. For example, the subframe offset of the DMTC information of the first cell received by the first base station and sent by the second base station is 9, and the first base station calculates the subframe offset of the DMTC window of the first cell at the subframe timing of the first base station to be 1, and then the first base station sets the subframe offset of the DMTC information of the first cell to be 1 and stores the set subframe offset.

In the first embodiment of the present invention, after the step 102 is executed, the method further includes a step of sending, to the terminal, the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station serving cell. The specific implementation manner of the step of sending the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station cell to the terminal is as follows: and according to the stored DMTC information of the first cell, configuring a Radio Resource Control (RRC) cell through system broadcasting or special measurement to send the DMTC information of the same-frequency adjacent cell and/or the DMTC information of the different-frequency adjacent cell of the first base station cell to the terminal. It can be understood that, when the first base station sends the same-frequency neighbor cell DMTC information and/or different-frequency neighbor cell DMTC information of the first base station cell to the terminal, the first base station may send the same-frequency neighbor cell DMTC information and/or different-frequency neighbor cell DMTC information of the first base station cell to the terminal based on the DMTC information stored in one or more first cells by itself. Therefore, the terminal can measure the DRS signal quality in the DMTC window of the adjacent cell, and the effect of reducing the power consumption of the terminal is achieved.

In the first embodiment of the present invention, the X2 interface message may be an X2setup request message, an X2setup response message, a base station configuration update response message, or a DMTC response message. It should be noted that, regardless of the above-mentioned X2 interface message, the DMTC Information of the first Cell is recorded in the Serving Cell DMTC Information field newly added in the neighbor Information (neighbor Information) field in the X2 interface message. As can be seen, the Serving Cell DMTC information field is used for the second base station to transmit the first DMTC information, that is, the local Cell DMTC information of the first Cell.

When the DMTC Information of the first Cell includes the first DMTC Information, that is, when the neighbor Information includes the Serving Cell DMTC field. The encoding format of the Serving Cell DMTC information field may be as shown in table 1,

When the DMTC information of the first Cell comprises first DMTC information and second DMTC information, the NeighbourInformation field further comprises an intra-f Cell DMTC field and an Inter-f Cell DMTC field which are newly added, wherein the Serving Cell DMTC information field is used for transmitting the first DMTC information, and the intra-f Cell DMTC field and the Inter-f Cell DMTC field are used for transmitting the second DMTC information.

In the first embodiment of the present invention, if the first base station receives the DMTC information of the first cell sent by the second base station through the X2 interface message, the following ways may exist in the interaction process between the first base station and the second base station according to the difference of the X2 interface message.

As shown in fig. 2, the first interaction manner is: after the first base station sends an X2 establishment Request (X2Setup Request) message to the second base station, receiving an X2 establishment Response (X2Setup Response) message which is sent by the second base station and contains the DMTC information of the first cell; or, the first base station receives an X2Setup Request message containing DMTC information of the first cell sent by the second base station in the process of establishing an X2 interface with the second base station.

Wherein, the second interaction mode is as follows: after establishing the X2 interface between the first base station and the second base station,

the first base station receives a base station configuration UPDATE (ENB configuration UPDATE) message/base station configuration UPDATE response (ENB configuration UPDATE) message which is sent by the second base station and contains the DMTC information of the first cell.

As shown in fig. 3, the third interaction mode is: and adding a special DMTC request message and a DMTC response message, wherein the first base station sends the DMTC information request message to the second base station through an X2 interface, and then receives the DMTC response message which is sent by the second base station and contains the DMTC information of the first cell.

In the first embodiment of the present invention, the S1 interface message may be a base station configuration forwarding message, a core network control node configuration forwarding message, or a DMTC response message.

When the S1 interface message is a base station CONFIGURATION forwarding (eNB CONFIGURATION TRANSFER) message, as shown in fig. 4, an interaction manner between the first base station and the second base station is as follows: the first base station sends an eNB CONFIGURATION transmission message to a core network control node (e.g., a Mobile Management Entity (MME)) to request the DMTC information of the first cell sent by the second base station, and then receives the DMTC information of the first cell sent by the second base station forwarded by the core network control node through a core network control node CONFIGURATION forwarding (CONFIGURATION transmission) message. Wherein the DMTC Information of the first cell is contained in a self-optimizing network Information response (Son Information) field of the self-optimizing network Information (Son Information) field.

Of course, the first base station may also directly receive, through the core network control node configuration forwarding message, the DMTC information of the first cell sent by the second base station forwarded by the core network control node. Wherein the DMTC Information of the first cell is contained in a self-optimization network Information Request (Son Information Request) field of the Son Information field.

In the first embodiment of the present invention, a DMTC information field is added to a self-optimized network CONFIGURATION forwarding (Son CONFIGURATION TRANSFER) field of a core network control node CONFIGURATION TRANSFER or ENB CONFIGURATION TRANSFER message, and is used by the second base station to send DMTC information of the first cell. Or, a request type (enumeration value) of DMTC Information is added to a Son Information request field of a Son Information field in a Son CONFIGURATION TRANSFER field of a core network control node CONFIGURATION TRANSFER or an ENB CONFIGURATION TRANSFER message, so that the first base station requests the second base station to transmit DMTC Information of the first cell, and a self-optimization network Information response (Son Information Reply) field of the Son Information field of the core network control node CONFIGURATION TRANSFER or the ENB CONFIGURATION TRANSFER message is added with a DMTC Information field for the second base station to transmit DMTC Information of the first cell.

The neighbor Information in the Serving Cell Information of the DMTC Information field includes a Serving Cell DMTC field for transmitting the first DMTC Information, that is, the DMTC Information of the first Cell.

Wherein, the format of the Son Configuration Transfer field can be as shown in Table 5,

In the first embodiment of the present invention, when the S1 interface message is a DMTC response message, as shown in fig. 5, an interaction manner between the first base station and the second base station is as follows: and adding a dedicated DMTC request message and a DMTC response message, wherein the DMTC request message is sent to a core network control node (MME or Serving GPRS Support Node (SGSN)) by the first base station through an S1 interface, the DMTC request message is forwarded to the second base station by the core network control node, and then the DMTC response message sent by the second base station and forwarded by the core network control node is received, wherein the DMTC response message comprises the DMTC information of the first cell.

Certainly, the DMTC request message may be forwarded by the core network control node of the second base station, that is, the core network control node of the first base station first sends the DMTC request message to the core network control node of the second base station, and then the core network control node of the second base station forwards the DMTC request message to the second base station.

Therefore, in the first embodiment of the present invention, the first base station acquires the DMTC information of the first cell (where the first cell is a neighboring cell of the serving cell of the second base station) sent by the second base station through the neighboring cell information of the second base station, and stores the acquired DMTC information of the first cell in the neighboring cell information of the second base station, so that the first base station can send the DMTC information of the same-frequency neighboring cell and/or the DMTC information of the different-frequency neighboring cell of the first base station to the terminal according to the stored DMTC information of the first cell, thereby achieving the effect of enabling the terminal to perform DRS signal quality measurement in the DMTC window of the neighboring cell and reducing the power consumption of the terminal.

It should be further noted that there is no strict sequence relationship between the

steps

601 and 602. Since the DMTC information of the first cell related to step 601 is already described in detail in the first embodiment, no redundant description is repeated in this embodiment to avoid too many repetitions.

In a second embodiment of the present invention, a specific implementation manner of receiving the DMTC information of the second cell in step 602 is as follows: and receiving the DMTC information of the second cell sent by the second base station according to the X2 interface message or the S1 interface message. Wherein, the DMTC information of the second cell is recorded in the serving cell information of the second base station of the X2 interface message or the S1 interface message. It should be noted that, in order to facilitate the first base station to identify the second cell, the X2 interface message and the S1 interface message each include a network identity (NHN-ID) and a cell global identifier (ECGI) of the second cell.

In a second embodiment of the present invention, a specific implementation manner of storing the DMTC information of the second cell in step 602 is as follows: detecting whether the received DMTC information of the second cell contains subframe offset or not, wherein if the received DMTC information of the second cell contains the subframe offset, converting the subframe offset of the received DMTC information of the second cell into the subframe offset of a DMTC window at the subframe timing of the first base station to obtain the DMTC information of the second cell after subframe offset conversion processing, and storing the DMTC information of the second cell after the subframe offset conversion processing in the service cell information of the second base station; in a specific implementation, the first base station may acquire subframe timing of the second cell by monitoring a downlink synchronization signal of the second cell, so as to convert a subframe offset of the received DMTC information of the second cell into a subframe offset at the subframe timing of the first base station, where the second cell is synchronous or asynchronous with the first base station.

Another specific implementation manner of saving the DMTC information of the second cell in step 602 is as follows: determining whether the second cell is asynchronous with the first base station; if the second cell is asynchronous with the first base station, the DMTC information of the second cell not including the subframe offset (i.e., except the subframe offset) is stored in the serving cell information of the second base station. The method for the first base station to determine whether the second cell is asynchronous comprises the following steps: if the received DMTC information of the second cell does not contain subframe offset, determining that the second cell is asynchronous with the first base station; or the first base station determines that the second cell is asynchronous with the first base station according to the synchronization information about the second cell configured by the OAM; alternatively, the first base station determines that the second cell is asynchronous with the first base station by querying the second base station for synchronization information. For example, the first base station may query the second base station for synchronization information through a base station Configuration Transfer (eNB Configuration Transfer) message of the S1 interface, where the first base station sets a sonlnformation Request field of the eNB Configuration Transfer to a Time synchronization information (Time synchronization Info) enumeration value; the second base station sends an S1 message eNB Configuration Transfer containing synchronization information to the first base station to indicate whether to be asynchronous with the first base station. Further, if the first base station determines that the second cell is synchronous with the first base station, the first base station may convert the received subframe offset of the DMTC information of the second cell into a subframe offset of the DMTC window at the subframe timing of the first base station to obtain the DMTC information of the second cell after the subframe offset conversion, and store the DMTC information of the second cell after the subframe offset conversion in the serving cell information of the second base station.

It should be noted that, when the received DMTC information of the second cell includes a subframe offset, whether to convert the subframe offset of the received DMTC information of the second cell mainly depends on whether the subframe offset of the received DMTC information of the second cell has been converted. Specifically, if the subframe offset has been converted when the second base station sends the DMTC information of the second cell, the first base station does not need to convert the subframe offset when receiving the DMTC information of the second cell, and directly stores the received DMTC information of the second cell in the serving cell information of the second base station; if the second base station does not convert the subframe offset when sending the DMTC information of the second cell, the first base station needs to convert the subframe offset when receiving the DMTC information of the second cell, and after the conversion, the DMTC information of the second cell after the subframe offset conversion processing is stored in the serving cell information of the second base station.

In the second embodiment of the present invention, after the step 602 is executed, the method further includes a step of sending the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station cell to the terminal. The specific implementation manner of the step of sending the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station cell to the terminal is as follows: and according to the stored DMTC information of the first cell and/or the DMTC information of the second cell, configuring a Radio Resource Control (RRC) cell through system broadcasting or special measurement to send the same-frequency adjacent cell DMTC information and/or different-frequency adjacent cell DMTC information of the first base station cell to the terminal. It can be understood, of course, that when the first base station sends the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station cell to the terminal, the first base station may send the same-frequency neighbor cell DMTC information and/or the different-frequency neighbor cell DMTC information of the first base station cell to the terminal based on the DMTC information of one or more first cells and/or the DMTC information of one or more second cells stored by the first base station itself. Therefore, the terminal can measure the DRS signal quality in the DMTC window of the adjacent cell, and the effect of reducing the power consumption of the terminal is achieved.

In the second embodiment of the present invention, the X2 interface message may be an X2setup request message, an X2setup response message, a base station configuration update response message, or a DMTC response message. In addition, regardless of the X2 interface message, the DMTC Information of the second Cell is recorded in the Serving Cell DMTC Information field newly added to the Serving Cell Information field in the X2 interface message. As can be seen, the Serving Cell DMTC information field is used for the second base station to transmit the third DMTC information, that is, the DMTC information of the local Cell of the second Cell. Of course, if the DMTC Information of the second Cell further includes fourth DMTC Information, a neighbor Cell DMTC field may be further added in the ServingCell Information for transmitting the fourth DMTC Information.

In the second embodiment of the present invention, the S1 interface message may be a base station configuration forwarding message, a core network control node configuration forwarding message, or a DMTC response message.

Referring to the first embodiment, describing the transmission process of the DMTC Information of the second cell, if there is no X2 interface between the first base station and the second base station, the first base station sends an eNB CONFIGURATION transmission message to the core network control node to request the second base station to send the DMTC Information (i.e., the DMTC Information of the second cell), and then receives, through the core network control node CONFIGURATION transmission message, the DMTC Information sent by the second base station and forwarded by the MME, where the DMTC Information is included in a Son Information Response field of the Son Information field. Or, the first base station directly receives, through the core network control node CONFIGURATION TRANSFER message, DMTC Information sent by the second base station and forwarded by the MME, where the DMTC Information is included in a Son Information Request field of the Son Information field.

The method includes the steps of adding a DMTC Information Request field in a Son CONFIGURATION TRANSFER field of a core network control node CONFIGURATION TRANSFER or ENB CONFIGURATION TRANSFER message to Request a second base station to send DMTC Information by a first base station, and adding a DMTC Information field in a Son Information Reply field of a Son Information TRANSFER field in a core network control node CONFIGURATION TRANSFER or ENB CONFIGURATION TRANSFER message to send DMTC Information by the second base station. Or, adding a DMTC information field in a Son CONFIGURATION TRANSFER field of the MME CONFIGURATION TRANSFER or the enb CONFIGURATION TRANSFER message, for the first base station to receive the DMTC information sent by the second base station. The Serving Cell DMTC field includes a Serving Cell DMTC for transmitting a third DMTC message, i.e., the local Cell DMTC message of the second Cell, and the neighbor Information in each Serving Cell Information includes a Serving Cell DMTC field for transmitting a first DMTC message, i.e., the local Cell DMTC message of the first Cell, and may further include an Intra-f Cell DMTC message and an Inter-f Cell DMTC message for transmitting a fourth DMTC message. Wherein, the format of the DMTC information field can be as shown in Table 10,

watch 10

Here, the parameters in table 10 are explained. Specifically, BIT STRING represents a BIT STRING. It should be noted that, since other parameters in table 10 are already shown and explained in the foregoing tables 1 to 9, the explanation is not repeated here.

It can be seen that, in the second embodiment of the present invention, the DMTC information of the first cell (the first cell is a neighboring cell of the serving cell of the second base station) and the DMTC information of the second cell (the second cell is the serving cell of the second base station) sent by the second base station through the neighboring cell information of the second base station are received by the first base station, and stores the received DMTC information of the first cell in the neighboring cell information of the second base station, meanwhile, the received DMTC information of the second cell is stored in the service cell information of the second base station, the first base station can send the DMTC information of the same-frequency adjacent cell and/or the DMTC information of the different-frequency adjacent cell of the first base station cell to the terminal according to the stored DMTC information of the first cell and/or the stored DMTC information of the second cell, and further, the terminal can measure the DRS signal quality in the DMTC window of the adjacent cell, and the power consumption of the terminal is reduced.

Fifth embodiment

As shown in fig. 9, a fifth embodiment of the present invention provides a method for acquiring DMTC information configured by neighbor discovery signal measurement time, which is applied to a second base station, and includes:

step 901, obtaining DMTC information of the first cell.

The first cell is a neighbor cell of a serving cell of the second base station.

In a fifth embodiment of the present invention, a specific implementation manner of the step 901 is as follows: acquiring DMTC information of a first cell from a base station to which the first cell belongs through an X2 interface or an S1 interface; alternatively, the DMTC information of the first cell is acquired from operation, administration and maintenance (OAM) configuration information.

Step 902, sending the obtained DMTC information of the first cell to the first base station through the neighboring cell information of the second base station.

In a fifth embodiment of the present invention, a specific implementation manner of the step 902 is as follows: firstly, recording the acquired DMTC information of a first cell in the adjacent cell information of a second base station; and then sending the neighbor cell information of the second base station, which records the acquired DMTC information of the first cell, to the first base station according to the X2 interface message or the S1 interface message. The X2 interface message may be an X2 establishment request message, an X2 establishment response message, a base station configuration update response message, or a DMTC response message; the S1 interface message may be a base station configuration forwarding message, a core network control node configuration forwarding message, or a DMTC response message. It should be noted that, in order to facilitate the first base station to identify the first cell, the X2 interface message and the S1 interface message each include a network identity (NHN-ID) and a cell global identifier (ECGI) of the first cell.

In a fifth embodiment of the present invention, the obtained DMTC information of the first cell includes: the first DMTC information and/or the second DMTC information. The first DMTC information is local cell DMTC information of the first cell, and the second DMTC information is same-frequency adjacent cell DMTC information and/or different-frequency adjacent cell DMTC information of the first cell.

In a specific implementation, the second base station may obtain the DMTC information of the first cell from the third base station by using a method similar to the second embodiment in which the first base station obtains the DMTC information of the first cell or the DMTC information of the second cell from the second base station, that is, receiving, through an X2 interface message or an S1 interface message, the DMTC information of the first cell sent by the third base station through the neighboring cell information or the serving cell information of the third base station. The first cell is a serving cell or a neighboring cell of the third base station.

In a fifth embodiment of the present invention, the step of sending the obtained DMTC information of the first cell to the first base station in step 902 includes two specific implementation manners. The first specific implementation manner is as follows: firstly, converting subframe offset in DMTC information of a first cell into subframe offset of a DMTC window at subframe timing of a first base station to obtain DMTC information of the first cell after subframe offset conversion processing; and then sending the DMTC information of the first cell after the subframe offset conversion processing to the first base station. In a specific implementation, the second base station may obtain the subframe timing of the first cell by monitoring a downlink synchronization signal of the first cell, and/or obtain the subframe timing of the first base station by monitoring a downlink synchronization signal of a serving cell of the first base station, so as to convert the obtained subframe offset of the DMTC information of the first cell into the subframe offset at the subframe timing of the first base station, where the first cell is synchronous or asynchronous with the first base station.

The above procedure for subframe offset conversion processing is described herein in one specific implementation. As shown in fig. 10, for example, the subframe offset of the DMTC window of the first cell is 9, the second base station calculates the subframe offset of the DMTC window of the first cell at the subframe timing of the first base station to be 1, and the second base station sets the subframe offset in the DMTC information of the first cell to be 1 and then sends the subframe offset to the first base station.

The second specific implementation manner is as follows: and detecting whether the first cell is asynchronous with the first base station, if the first cell is asynchronous with the first base station, deleting the subframe offset in the acquired DMTC information of the first cell, and sending the DMTC information of the first cell after the subframe offset is deleted to the first base station. The method for the second base station to detect whether the first cell is asynchronous with the first base station comprises the following steps: the second base station determines that the first cell is asynchronous with the first base station according to the synchronization information about the first cell and/or the synchronization information about the first base station configured by the OAM; alternatively, the second base station determines that the first cell is asynchronous with the first base station by querying the base station to which the first cell belongs for synchronization information. For example: the second base station may inquire about the synchronization Information of the base station to which the first cell belongs through a base station configuration forwarding (enb configuration Transfer) message of an S1 interface, wherein the second base station sets a SON Information Request field of the enb configuration Transfer to a time synchronization Information (time synchronization Information) enumeration value; and the base station to which the first cell belongs sends an S1 message eNB Configuration Transfer containing synchronization information to the second base station after receiving the message to indicate whether the first cell is asynchronous with the second base station. If the first cell is synchronized with the second base station and the second base station is synchronized with the first base station, the second base station may determine that the first cell is synchronized with the first base station; otherwise, the second base station determines that the first cell is asynchronous with the first base station. Further, if the second base station determines that the first cell is synchronous with the first base station, the second base station may also convert the subframe offset in the DMTC information of the first cell into the subframe offset of the DMTC window at the subframe timing of the first base station, so as to obtain the DMTC information of the first cell after the subframe offset conversion; and then sending the DMTC information of the first cell after the subframe offset conversion processing to the first base station.

In a fifth embodiment of the present invention, the method further includes the following steps:

in the first step, DMTC information of a second cell is obtained.

Wherein, the second cell is a service cell of the second base station, and the DMTC information of the second cell includes: and the third DMTC information is the DMTC information of the local cell of the second cell. Of course, the obtained DMTC information of the second cell may further include fourth DMTC information, where the fourth DMTC information is the same-frequency neighboring cell DMTC information and/or different-frequency neighboring cell DMTC information of the second cell, that is, the fourth DMTC information is cell DMTC information related to the broadcast of the local cell of the second cell.

And step two, sending the acquired DMTC information of the second cell to the first base station through the service cell information of the second base station.

In a fifth embodiment of the present invention, a specific implementation manner of the second step may be: firstly, recording the acquired DMTC information of the second cell in the service cell information of the second base station; and then, according to the X2 interface message or the S1 interface message, sending the service cell information of the second base station, in which the acquired DMTC information of the second cell is recorded, to the first base station. It should be noted that, in order to facilitate the first base station to identify the second cell, the X2 interface message and the S1 interface message each include a network identity (NHN-ID) and a cell global identifier (ECGI) of the second cell.

In a fifth embodiment of the present invention, the step of sending the obtained DMTC information of the second cell to the first base station includes two specific implementation manners.

The first specific implementation manner is as follows: firstly, converting subframe offset in DMTC information of a second cell into subframe offset of a DMTC window under subframe timing of a first base station to obtain DMTC information of the second cell after subframe offset conversion processing; and then sending the DMTC information of the second cell after the subframe offset conversion processing to the first base station. The second base station may acquire the subframe timing of the first base station by monitoring a downlink synchronization signal of the serving cell of the first base station, so as to convert the subframe offset of the DMTC information of the second cell into the subframe offset at the subframe timing of the first base station, where the second cell is synchronous or asynchronous with the first base station.

The second specific implementation manner is as follows: and detecting whether the second cell is asynchronous with the first base station, if so, deleting the subframe offset in the acquired DMTC information of the second cell, and sending the DMTC information of the second cell after the subframe offset is deleted to the first base station. The method for the second base station to detect whether the second cell is asynchronous with the first base station comprises the following steps: the second base station determines that the second cell is asynchronous with the first base station according to the OAM configuration and the synchronous information about the first base station; alternatively, the second base station determines that the second cell is asynchronous with the first base station by querying the first base station for synchronization information. For example: the second base station may inquire about the synchronization Information of the first base station through a base station Configuration Transfer (eNB Configuration Transfer) message of the S1 interface, wherein the second base station sets a SON Information Request field of the eNB Configuration Transfer to a Time synchronization Information (Time synchronization Info) enumeration value; and the first base station sends an S1 message eNB Configuration Transfer containing synchronization information to the second base station after receiving the message to indicate whether the first base station is asynchronous with the second base station, and if the first base station is indicated to be asynchronous with the second base station, the second base station judges that the first base station is asynchronous with the second cell. Further, if the second base station determines that the second cell is synchronous with the first base station, the second base station may also convert the subframe offset in the DMTC information of the second cell into the subframe offset of the DMTC window at the subframe timing of the first base station, to obtain the DMTC information of the first cell after the subframe offset conversion; and then sending the DMTC information of the second cell after the subframe offset conversion processing to the first base station.

Therefore, in the fifth embodiment of the present invention, by acquiring the DMTC information of the first cell (where the first cell is a neighboring cell of the serving cell of the first base station), and sending the DMTC information of the first cell to the first base station through the neighboring cell information of the second base station, the first base station can send the same-frequency neighboring cell DMTC information and/or different-frequency neighboring cell DMTC information of the first base station cell to the terminal according to the received DMTC information of the first cell, so that the terminal can perform DRS signal quality measurement in the DMTC window of the neighboring cell, and the power consumption of the terminal is reduced.
