Description

Method, device, base station and terminal for establishing neighbor relation

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a base station, and a terminal for establishing a neighbor relation.

Background

MulteFire is a radio access technology that extends LTE to unlicensed bands, which 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 WiFi carrier sensing technique.

MulteFire provides two basic access mode Network architectures, namely, a Public Land Mobile Network (PLMN) access mode and a Neutral Host Network (NHN) access mode. The NH access mode is a neutral network with unified planning and self-organization newly introduced by MulteFire, one NHN can be shared to a plurality of Service providers at the same time, the MF RAN is connected to a Core Network (CN) of the NHN, the broadcast message of the MF cell sends NH network ID (NHN-ID) and Service Provider identification (PSP-ID), and the UE is not supported to switch between the MF network with the NHN access mode and the 3GPP network at present. The PLMN access mode is a network mode in which the MF RAN is connected to a 3GPP CN of a mobile operator, the UE can perform S1 or X2 handover between the MF RAN in the PLMN access mode and the 3GPP RAN, and a PLMN ID list is sent in a broadcast message of an MF cell. In addition, there is a hybrid access mode where the MF RAN is connected to both the NHN CN and the 3GPP CN, and the NHN-ID, the PSP-ID and the PLMN ID list are broadcast simultaneously in a broadcast message of the MF cell.

An Automatic Neighbor Relation (ANR) function introduced in the 3GPP standard is used for a base station to discover a Neighbor cell according to a measurement report of the UE and to automatically configure a Neighbor Relation Table (NRT) so as to reduce the complexity and workload of an operator in manually configuring the NRT. Each Cell in the base station has an NRT, and the neighbor relation information for each neighbor Cell in the NRT includes a Target Cell Identity (TCI) and three parameters (noremovive/NoX 2/NoHO), where the TCI includes a Physical Cell Identity (PCI) and a Cell Global Identity (CGI), and the noremovive parameter is set to indicate that the neighbor Cell cannot be deleted from the NRT, the NoX2 is set to indicate that an X2 signaling flow cannot be performed between the neighbor Cell and the NRT, and the NoX indicates that handover to the neighbor Cell cannot be performed.

The implementation process of the 3GPP network ANR function is shown in fig. 1, where Type of CellA is LTE, Phy-CID is 13, and Global-CID is 17; UTRAN Type of CellB, PSC 5 of Phy-CID, and 19 of Global-CID. The base station sends a measurement command Report neighbor Request (RAT, Frequency) to the UE to indicate the UE to carry out periodic neighbor cell measurement, and the base station sets the periodic measurement purpose as Report Strongest Cells or Report Strongest Cells For SON; after Receiving the measurement command, the UE periodically reports a neighboring cell measurement result Report neighbor Response (Phy-CID, Signal level) to the base station, where the neighbor measurement result Report neighbor Response includes a PCI of the neighboring cell and a Reference Signal Receiving Power (RSRP) and/or a Reference Signal Receiving Quality (RSRQ) of the neighboring cell; if the current NRT does not have the neighbor Cell information corresponding To the PCI reported by the UE, the base station sends a measurement command Report Global-CID Request (Target Phy-CID is 5) To the UE To indicate the UE To inquire the CGI information corresponding To the specified PCI, and the base station sets the measurement purpose as a Cell For Which To Report CGI; the method comprises the steps that UE reads system broadcast information of a cell corresponding to PCI and obtains CGI information of the cell, wherein the CGI information comprises CGI, a location area and a PLMN list; the UE reports the read CGI information Report Global-CID of the cell corresponding to the PCI to the base station, which is 19, and the base station may add an NRT to the cell to establish a neighboring cell relationship with the cell, and Report the new NRT to the OAM of the operator. And after the base station discovers the adjacent cell through the ANR function, an X2 interface can be established between the CGI of the adjacent cell and the base station of the adjacent cell.

However, currently, in the ANR function defined by the 3GPP standard, the UE reads a system broadcast message of a cell corresponding to a PCI specified by the base station, acquires CGI information of the cell, and reports the CGI information to the base station, where the CGI information includes a CGI and a location area, and may further include a PLMN ID list, where the CGI and the PLMN ID list include network and operator identifiers (i.e., PLMN IDs). For an MF neighboring cell in an NHN access mode or a hybrid access mode, if, according to the prior art, the UE only reads the CGI and the PLMN ID list in the MF cell system broadcast, and cannot obtain the network identifier and the service provider identifier of the actual NHN access mode, the base station cannot obtain sufficient neighboring cell information, and further cannot support the base station and the MF cell to automatically establish a neighboring cell relationship and an X2 interface.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Aiming at the MF neighboring cells in an NHN access mode or a hybrid access mode in the prior art, the UE only reads a CGI and a PLMN ID list in MF cell system broadcast and cannot obtain the network identifier and the service provider identifier of the actual NHN access mode, and the base station cannot obtain enough neighboring cell information, so that the base station cannot support the automatic establishment of the neighboring cell relationship and the X2 interface with the MF cell. The following embodiments of the present invention provide a method, an apparatus, a base station, and a user terminal for establishing a neighboring cell relationship, where a first base station determines a target cell through acquired PCI information, and then acquires CGI information carrying NHN-ID information of the target cell to obtain sufficient MF neighboring cell information, so as to support adding the target cell to a neighboring cell relationship list of a first base station serving cell, and further, when establishing a neighboring cell relationship between the first base station serving cell and the target cell, a handover parameter and an X2 interface in the neighboring cell relationship information may be set according to the CGI information of the target cell.

First embodiment

As shown in fig. 2, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 21: and determining the neighbor cell which does not exist in the neighbor cell relation list of the serving cell of the first base station as the target cell.

The serving cell of the first base station may be different types of serving cells in different access modes, such as: a 3GPP cell, an MF cell in PLMN access mode or an MF cell in NHN access mode. The target cell may also be a different type of serving cell in a different access mode.

Specifically, when the neighbor cell relation list NRT of the serving cell of the first base station does not have the neighbor cell information in the terminal neighbor cell measurement result; or when the monitored neighbor cell information does not exist in the NRT of the serving cell of the first base station, determining the neighbor cell as a target cell.

Step 22: and acquiring Cell Global Identity (CGI) information of the target cell.

The CGI information is carried in a system broadcast message of the target cell, and the CGI information at least includes an indication field indicating whether the NHN-ID of the target cell is included. When the indication field in the CGI information indicates that the indication field includes the NHN-ID of the target cell, the CGI information includes the NHN-ID of the target cell, and the target cell is determined to be an MF cell in the NHN access mode, otherwise the target cell is determined to be an MF cell in the PLMN access mode or a 3GPP cell.

The first base station may directly obtain CGI information sent by the target cell through a system broadcast message. Specifically, the first base station temporarily interrupts the current communication service to the terminal UE, and resumes the communication service to the UE after reading the CGI information of the target cell; alternatively, the first base station may also read the CGI information of the target cell using the idle time.

Further, the CGI information of the target cell may further include: part or all of the service provider identity PSP-ID list broadcasted by the target cell, i.e. the CGI information includes: NHN-ID of the target cell and partial or all PSP-ID lists broadcasted by the target cell; of course, the CGI information may also include only the NHN-ID of the target cell.

Specifically, there are various PSP-ID types in the MF cell in the current NHN access mode, for example, a PLMN-based PSP-ID, an organization identifier-based PSP-ID, and a short format PSP-ID calculated based on the HASH function, and the system broadcast of the MF cell may send different types of PSP-ID lists. In addition, the PSP-ID list for the MF cell may also be transmitted in one or more system broadcast messages, e.g., the PSP-ID list is transmitted in multiple SIBs (i.e., in SIB-MF and SIBx, where SIBx may be SIB3-SIB 19).

Step 23: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

When the indication field in the CGI information indicates that the NHN-ID of the target cell is included, specifically, when the indication field of the CGI information includes the NHN-ID of the target cell, the TCI information of the target cell includes: the physical cell identity PCI of the target cell, the E-UTRAN cell global identity ECGI and the NHN-ID.

Thus, a target cell is determined through the obtained PCI information, and then CGI information carrying NHN-ID information of the target cell is obtained to obtain sufficient MF neighbor cell information, thereby supporting the target cell to be added to the neighbor cell relation list of the first base station serving cell, and further, when the neighbor cell relation is established between the first base station serving cell and the target cell, the switching parameter and the X2 interface in the neighbor cell relation information can be set according to the CGI information of the target cell.

Second embodiment

As shown in fig. 3, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 31: and sending a first measurement configuration message to a terminal in a service cell of a first base station to indicate the terminal to perform periodic neighbor cell measurement.

Step 32: and the receiving terminal carries out periodic neighbor cell measurement according to the first measurement configuration message to obtain and report a measurement result.

Wherein, the measurement result carries the neighboring PCI.

Step 33: and detecting whether the adjacent cell corresponding to the PCI exists in an adjacent cell relation list of a service cell of the first base station.

Step 34: and if not, determining the adjacent cell as the target cell.

Step 35: and acquiring Cell Global Identity (CGI) information of the target cell.

The CGI information is carried in a system broadcast message of the target cell, and the CGI information at least comprises an indication field indicating the NHN-ID of the target cell. Wherein, when the indication field in the CGI information indicates that the indication field includes the NHN-ID of the target cell, it is determined that the target cell is an MF cell of the NHN access mode, otherwise, it is determined that the target cell is an MF cell of the PLMN access mode or a 3GPP cell.

Step 36: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

Third embodiment

As shown in fig. 4, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 41: and determining the neighbor cell which does not exist in the neighbor cell relation list of the serving cell of the first base station as the target cell.

The specific manner of determining the target cell can refer to steps 31 to 34 in the second embodiment, and therefore, the detailed description thereof is omitted here.

Step 42: and sending a second measurement configuration message to the terminal in the serving cell of the first base station to indicate the terminal to acquire and report the CGI information of the target cell.

When the NRT of the service cell of the first base station does not have the neighbor cell information corresponding to the PCI in the MF neighbor cell measurement result reported by the UE; or, when the neighbor cell information corresponding to the PCI monitored by the base station does not exist in the NRT of the serving cell, that is, after the target cell is determined, the base station sends a second measurement configuration message to the UE to instruct the UE to query the CGI information of the neighbor cell corresponding to the PCI. And the first base station sets the measurement purpose in the second measurement configuration message as report CGI.

Wherein, the CGI information of the target cell may further include: some or all of the service provider identification PSP-ID lists broadcast by the target cell, e.g., the CGI information may include only the PSP-ID list in the SIB-MF broadcast by the target cell or only the PSP-ID list in the SIBx broadcast by the target cell, or the CGI information may include the PSP-ID lists in the SIB-MF and the SIBx broadcast by the target cell.

However, since the time delay for acquiring the PSP-ID list is long, the first measurement reporting indication information may be configured in the second measurement configuration message, and is used to indicate the terminal to acquire and report the NHN-ID and a part or all of the PSP-ID list in the CGI information of the target cell. Specifically, the first measurement reporting indication information may be a measurement reporting indication field newly added in a measurement object IE or a measurement report configuration IE of the second measurement configuration message by the first base station, or any field in an existing measurement configuration message, and is used to instruct the UE to read and report a PSP-ID list in a target cell broadcast when reporting CGI information of the target cell. Further, the first measurement report indication information may also be used to indicate the UE to report a PSP-ID list in the SIB-MF broadcasted by the target cell, a PSP-ID list in the SIBx broadcasted by the target cell, or all PSP-ID lists broadcasted by the target cell. For example, the first measurement reporting indication information is a si-RequestForHO field in a measurement report configuration IE in the second measurement configuration message, and is used for reading and reporting a PSP-ID list in a target cell broadcast when the UE reports the CGI information of the target cell, and the si-RequestForHO field is not set and is used for indicating the UE not to report the broadcast PSP-ID list of the target cell.

Further, the second measurement configuration message further includes: and the second measurement reporting indication information is used for indicating the terminal to autonomously control the time gap for acquiring the CGI information of the target cell. The second measurement reporting indication information may be a measurement reporting indication field newly added in a measurement object IE or a measurement report configuration IE of the second measurement configuration, or any field in an existing measurement configuration message. For example, the second measurement reporting indication information is a si-RequestForHO field in the measurement report configuration IE in the second measurement configuration message, the si-RequestForHO field is set to indicate that the UE autonomously controls to read the Gap of the CGI information, and the si-RequestForHO field is not set to indicate that the UE reads the CGI information in any IDLE (IDLE) state or autonomously controls to read the Gap of the CGI information.

Step 43: and receiving the CGI information of the target cell, which is obtained and reported by the terminal according to the second measurement configuration message.

The first base station can further optimize the network where the cell is located according to the NHN-ID and the PSP-ID list in the CGI information of the target cell reported by the UE. For example, collision detection is performed on NHN-IDs of different MF networks, different PSP-ID lists are scheduled to be sent in MF cell system broadcast messages with the same NHN-ID, etc.

Step 44: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

After receiving a measurement result sent by the UE after reading the CGI information of the target MF cell, the first base station adds the information of the target cell to the NRT of the serving cell of the first base station. When the indication field in the CGI information indicates that the NHN-ID of the target cell is included, specifically, when the indication field of the CGI information includes the NHN-ID of the target cell, the TCI information of the target cell includes: the physical cell identity PCI of the target cell, the E-UTRAN cell global identity ECGI and the NHN-ID.

Fourth embodiment

As shown in fig. 5, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 51: and determining the neighbor cell which does not exist in the neighbor cell relation list of the serving cell of the first base station as the target cell.

Step 52: and acquiring Cell Global Identity (CGI) information of the target cell.

The CGI information is carried in a system broadcast message of the target cell, and the CGI information at least comprises an indication field indicating the NHN-ID of the target cell.

Step 53: and sending a third measurement configuration message to the terminal in the serving cell of the first base station to indicate the terminal to report part or all of the PSP-ID list broadcasted by the target cell.

After receiving the CGI information of the target cell, the first base station may instruct the UE to report the broadcast PSP-ID list of the target cell by sending a third measurement configuration message. For example, when the CGI information of the target cell received by the first base station includes the NHN-ID but does not include the broadcast PSP-ID list, the first base station may instruct the UE to report the broadcast PSP-ID list of the target cell by sending the third measurement configuration message. For another example, when the first base station receives the CGI information of the target cell and only includes the PSP-ID list in the SIB-MF, in order to obtain the PSP-ID list broadcasted by the target cell in the SIBx, the first base station may instruct the UE to report the broadcasted PSP-ID list of the target cell by sending the third measurement configuration message.

Specifically, the third measurement configuration information includes: and the third measurement reporting indication information is used for indicating the terminal to report a part of or all PSP-ID lists broadcasted by the target cell. The third measurement reporting indication information may be a measurement reporting indication field newly added in a measurement object IE or a measurement report configuration IE of the third measurement configuration by the first base station, or any field in an existing measurement configuration message, and is used to indicate the UE to report the PSP-ID list broadcasted by the target cell. For example, the third measurement reporting indication information is an enumeration type reportPSP-ID of a measurement destination (purpose) field newly added in the measurement configuration IE of the measurement configuration message, and is used to indicate the UE to report the broadcast PSP-ID list of the target cell.

Further, the third measurement configuration information further includes: and the fourth measurement reporting indication information is used for indicating the terminal to report the specified PSP-ID list broadcasted by the target cell, namely indicating the UE to report different broadcasted PSP-ID lists. Specifically, the fourth measurement reporting indication information may be a measurement reporting indication field newly added by the first base station in a measurement object IE or a measurement report configuration IE configured by the third measurement, and the fourth measurement reporting indication information may be used to indicate the UE to report a PSP-ID list in an SIB-MF broadcasted by the target cell, a PSP-ID list in an SIBx broadcasted by the target cell, or all PSP-ID lists broadcasted by the target cell.

Step 54: and receiving a PSP-ID list which is acquired and reported by the terminal according to the third measurement configuration message.

Specifically, after receiving the measurement configuration message carrying the measurement destination field set as the reportPSP-ID, that is, after receiving the third measurement report indication information, the UE reads the broadcast PSP-ID list of the target cell and sends the broadcast PSP-ID list to the first base station. Specifically, a PSP information field (PSP-Info) is added to the E-UTRAN measurement result IE of the measurement result message, and the UE transmits the broadcast PSP-ID list of the MF cell in the PSP-Info field. And after receiving the measurement configuration message carrying the fourth measurement reporting indication information, the UE reads and reports the PSP-ID list in the SIB-MF broadcasted by the target cell, the PSP-ID list in the SIBx broadcasted by the target cell or all PSP-ID lists broadcasted by the target cell according to the fourth measurement reporting indication information.

Step 55: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

Fifth embodiment

As shown in fig. 6, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 61: and determining the neighbor cell which does not exist in the neighbor cell relation list of the serving cell of the first base station as the target cell.

Step 62: and acquiring Cell Global Identity (CGI) information of the target cell.

And step 63: and acquiring a PSP-ID list supported by the target cell.

Wherein, the PSP-ID list supported by the target cell at least includes: one of a list of all PSP-IDs supported by the target cell, a list of PSP-IDs transmitted by the target cell through a system broadcast message, and a list of PSP-IDs in the list of PSP-IDs supported by the target cell except the list of PSP-IDs transmitted by the system broadcast message.

After the first base station receives the CGI information of the target cell, the first base station may also obtain a PSP-ID list of the target cell in a network side signaling message manner. For example, when the first base station receives that the CGI information of the target cell includes the NHN-ID but does not include the broadcast PSP-ID list, the base station initiates, on the network side, a process of acquiring the broadcast PSP-ID of the target cell or a process of all PSP-ID lists supported by the target cell. For another example, when the CGI information of the target cell received by the first base station includes the broadcast PSP-ID list, in order to acquire all PSP-ID lists supported by the target cell, the first base station may also initiate, on the network side, a process of acquiring PSP-ID lists supported by the target cell in addition to the PSP-ID list sent in the broadcast message. In particular, this can be done with reference to the following:

as shown in fig. 7, the first method specifically includes:

step 71: a PSP-ID list request is sent over the X2 interface to the second base station to which the target cell belongs.

The PSP-ID list request is used for requesting to acquire a PSP-ID list supported by a target cell; the PSP-ID list request includes at least: NHN-ID of the target cell and ECGI information of the target cell.

Specifically, as shown in fig. 8, after the first base station establishes an X2 interface with the second base station to which the target cell belongs, a PSP-ID list request is sent to the second base station, and after receiving the PSP-ID list request, the second base station replies a PSP-ID list response to the first base station.

Alternatively, as shown in fig. 9, when the first base station establishes an X2 interface with the second base station to which the target cell belongs, a PSP-ID list Request is sent to the second base station through an X2Setup Request message. The second base station replies an X2Setup Response message to the first base station after receiving the PSP-ID list request, wherein the message comprises the NHN-ID, ECGI and PSP-ID list of the MF cell.

Step 72: receiving a PSP-ID list response sent by the second base station over the X2 interface in accordance with the PSP-ID list request.

After the first base station establishes an X2 interface with a second base station to which a target cell belongs, receiving a PSP-ID list response sent by the second base station through an X2 interface according to a PSP-ID request; or when the first base station establishes an X2 interface with the second base station to which the target cell belongs, receiving a PSP-ID list Response sent by the second base station through an X2Setup Response message according to the PSP-ID request.

Besides the above-mentioned manner of the X2 interface, the method can also be implemented by the S1 interface, as shown in fig. 10, the second manner specifically includes the following steps:

step 101: a PSP-ID list request is sent to the MME of the first base station over the S1 interface.

Step 102: and receiving a PSP-ID list response sent by the MME through an S1 interface according to the PSP-ID list request.

Specifically, as shown in fig. 11, when there is no X2 interface between the first base station and the second base station, or before the X2 interface is established between the first base station and the second base station, the first base station sends a PSP-ID list request of the S1 interface to its MME (S1AP message). Wherein, the S1AP message at least includes the NHN-ID and ECGI of the target cell, and when the MME receives the PSP-ID list request, the MME sends a PSP-ID list response to the first base station, where the PSP-ID list response includes the NHN-ID, ECGI, and PSP-ID list of the target cell.

Further, as shown in fig. 12, after the MME of the first base station receives the PSP-ID list request, if the PSP-ID list of the target cell is unknown, the MME of the first base station may initiate the PSP-ID list request to the second base station where the target cell is located, and when the second base station receives the PSP-ID list request, the MME of the first base station replies a PSP-ID list response to the MME of the first base station, where the PSP-ID list response includes the NHN-ID, ECGI, and PSP-ID list of the target cell, and after receiving the PSP-ID list response, the MME of the first base station forwards the PSP-ID list response to the first base station.

Further, in a specific implementation, the PSP-ID list request procedure initiated by the first base station may be implemented simultaneously with other S1 interface procedures, for example, the PSP-ID list request procedure and the X2 Transport Network Layer (TNL) address discovery procedure are performed simultaneously, using the same S1 message, or the PSP-ID list request procedure may be an S1 procedure implemented independently.

As shown in fig. 13, when the PSP-ID list request procedure and the X2TNL address discovery procedure are performed simultaneously, the first base station may initiate the PSP-ID list request and the X2TNL discovery procedure using the first eNB Configuration Transfer message that transmits the RAN Configuration information. Wherein, the SON Configuration Transfer field in the first eNB Configuration Transfer includes ECGI and NHN-ID of the target cell, and the SON Information Request field in the SON Configuration Transfer field includes indication Information requesting PSP-ID list and X2TNL address. After receiving the first eNB Configuration Transfer message sent by the first base station, the MME uses the first MME Configuration Transfer message to forward the SON Configuration Transfer field therein to the second base station where the target cell is located, the second base station uses the second eNB Configuration Transfer message to send the PSP-ID list and the X2TNL address contained in the SON Information Reply field of the SON Configuration Transfer field to the MME, and the MME uses the second MME Configuration Transfer message to forward the SON Configuration Transfer field in the second Configuration Transfer message to the first base station, so that the base station obtains the PSP-ID list and the X2TNL address of the target cell.

Further, the PSP-ID list request sent by the MME of the first base station to the second base station where the target cell is located may be forwarded by the MME of the second base station, that is, the MME of the first base station first sends the PSP-ID list request to the MME of the second base station, and then the MME of the second base station forwards the PSP-ID list request to the second base station.

Step 64: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

Sixth embodiment

As shown in fig. 14, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 141: and determining the neighbor cell which does not exist in the neighbor cell relation list of the serving cell of the first base station as the target cell.

Step 142: and acquiring Cell Global Identity (CGI) information of the target cell.

Step 143: and adding the target cell to a neighbor relation list of a serving cell of the first base station.

The first base station receives a measurement result sent after the UE reads CGI information of a target cell, and after the target cell is added to the NRT of the cell, may set a handover parameter NoX2/NoHO in neighbor relation information of the target cell in the NRT according to the CGI information of the target cell. Specifically, the following two kinds of determination of handover parameters may be included.

Step 144: NoH0 parameters are determined from the serving cell type of the first base station and the target cell type of the first base station among the serving cell to target cell handover parameters.

When the indication field in the CGI information of the target cell indicates that the NHN-ID of the target cell is included, determining that the type of the target cell is an MF cell in an NHN access mode, otherwise determining that the target cell is a 3GPP cell or an MF cell in a PLMN access mode. That is, the first base station determines the access mode of the target cell according to whether the CGI information of the target cell includes an NHN-ID, determines that the target cell is an MF cell in the NHN access mode if the CGI information includes the NHN-ID, and otherwise determines that the target cell is the MF cell in the PLMN access mode or the 3GPP cell. If the target cell is an MF cell of a PLMN access mode, a PLMN-ID list of the target cell can be obtained through CGI information; if the target cell is an MF cell of an NHN access mode, the HN-ID and the PSP-ID list of the target cell can be obtained through CGI information.

Specifically, determining NoH0 parameters in the handover parameters of the serving cell to the target cell of the first base station according to the type of the serving cell and the type of the target cell of the first base station includes the following scenarios:

scene one: when the type of the serving cell of the first base station is a 3GPP cell or an MF cell of a PLMN access mode.

If the target cell is the MF cell of the PLMN access mode, the neighbor cell switching parameter NoH0 parameter from the serving cell of the first base station to the target cell is not set; specifically, when the type of the serving cell of the first base station is a 3GPP cell or an MF cell in a PLMN access mode, if the target cell is the MF cell in the PLMN access mode and the PLMN-ID list in the CGI information of the target cell includes the specified PLMN-ID, the neighboring cell handover parameter NoH0 parameter from the serving cell of the first base station to the target cell is not set.

If the target cell is an MF cell in the NHN access mode, the neighbor cell handover parameter NoH0 parameter from the serving cell of the first base station to the target cell is set.

Scene two: when the serving cell type of the first base station is an MF cell in the NHN access mode.

If the target cell is an MF cell in the NHN access mode, the neighbor cell handover parameter NoH0 parameter from the serving cell of the first base station to the target cell is not set; specifically, when the serving cell type of the first base station is an MF cell in an NHN access mode, if the target cell is an MF cell in an NHN access mode and the NHN-ID of the target cell is the same as the NHN-ID of the serving cell of the first base station, the neighbor cell handover parameter NoH0 parameter from the serving cell of the first base station to the target cell is not set.

If the target cell is the MF cell of the PLMN access mode, the neighbor cell handover parameter NoH0 parameter from the serving cell of the first base station to the target cell is set.

Wherein when the parameter is not set NoH0, indicating that the UE is allowed to handover from the serving cell of the first base station to the target cell.

Step 145: and determining NoX2 parameters in the handover parameters from the serving cell to the target cell of the first base station according to the X2 interface state between the first base station and the second base station to which the target cell belongs.

Specifically, determining the NoX2 parameter in the handover parameters of the serving cell to the target cell of the first base station according to the X2 interface state between the first base station and the second base station includes the following scenarios:

scene three: when the serving cell to target cell handover parameter NoH0 parameter is not set.

If an X2 interface is established between the first base station and the second base station, not setting a NoX2 parameter in the switching parameters; in some possible embodiments, when no X2 interface is established between the first base station and the second base station, if the first base station fails to establish the X2 interface after initiating the establishment of the X2 interface to the second base station, the NoX2 parameter is set.

If an X2 interface is not established between the first base station and the second base station, setting a NoX2 parameter in the switching parameters; in some possible embodiments, when no X2 interface is established between the first base station and the second base station, if the first base station fails to establish the X2 interface after initiating the establishment of the X2 interface to the second base station, the NoX2 parameter is set.

Scene four: when the handover parameters NoHO parameter from the serving cell to the target cell has been set, the NoX2 parameter among the handover parameters is set.

Wherein, the NoHO parameter and the NoX2 parameter are set at the same time, which indicates that the UE is not allowed to be switched from the serving cell of the first base station to the target cell.

Ninth embodiment

The first to eighth embodiments above describe the method, apparatus, and base station for establishing a neighboring cell relationship according to the present invention from a base station side, respectively, and the following embodiments describe the method for establishing a neighboring cell relationship according to the present invention from a corresponding terminal side.

As shown in fig. 17, the method for establishing a neighboring cell relationship includes the following steps:

step 171: and receiving a second measurement configuration message which is sent by the first base station and indicates the terminal to report the CGI information of a target cell.

When the neighbor cell information corresponding to the PCI in the MF neighbor cell measurement result reported by the UE does not exist in the NRT of the serving cell of the first base station; or, when the neighbor cell information corresponding to the PCI monitored by the base station does not exist in the NRT of the serving cell, that is, after the target cell is determined, the base station sends a second measurement configuration message to the UE to instruct the UE to query the CGI information of the neighbor cell corresponding to the PCI.

Step 172: and acquiring and reporting the CGI information of the target cell according to the second measurement configuration message.

The CGI information is carried in a system broadcast message of the target cell, and the CGI information at least comprises an indication field indicating whether the CGI information contains a network address NHN-ID of a neutral host of the target cell.

After receiving a measurement configuration message sent by a first base station and reporting CGI information of a target cell, UE tries to read CGI information in a system broadcast message of the target cell. And after the UE successfully reads the CGI information of the target cell, the UE sends the read CGI information of the MF cell to the base station through the CGI information IE in the measurement result. The CGI information IE reported by the UE includes ECGI, TAC in the existing CGI information IE, or a PLMN ID list field, and adds an NHN-ID field.

When the target cell is an MF cell in a PLMN access mode, the UE can only read the ECGI, TAC, and PLMN ID list; when the target cell is an MF cell in an NHN access mode, the UE may read an NHN-ID in addition to the ECGI, the TAC, and the PLMN ID list. Therefore, the CGI information read and reported by the UE includes ECGI and TAC of the MF cell, and may further include a PLMN ID list, and if the system broadcast message of the MF cell includes NHN-ID, the UE should read and report the NHN-ID of the MF cell.

Wherein the CGI information further includes: part or all of the service provider identification PSP-ID list broadcast by the target cell. For example, the CGI information may include only the PSP-ID list in the SIB-MF broadcasted by the target cell or only the PSP-ID list in the SIBx broadcasted by the target cell, or the CGI information may include the PSP-ID lists in the SIB-MF and the SIBx broadcasted by the target cell. The UE may also read and report a broadcast PSP-ID list of the target cell, where the UE may report the partially read broadcast PSP-ID list of the MF cell.

The PSP-ID list includes: at least one of a first PSP-ID list based on a public land mobile network PLMN, a second PSP-ID list based on an organization identity OID, and a third PSP-ID list of short format calculated based on a HASH function.

The PSP-ID list is sent in one or more system broadcast messages carried in the target cell.

In this way, after the UE reports the CGI information carrying the NHN-ID information in the target cell to the first base station, the first base station can obtain sufficient MF neighbor cell information, thereby supporting adding the target cell to the neighbor cell relationship list of the serving cell of the first base station, and further, when the neighbor cell relationship is established between the serving cell of the first base station and the target cell, the UE can set the handover parameter and the X2 interface in the neighbor cell relationship information according to the CGI information of the target cell.

Tenth embodiment

As shown in fig. 18, an embodiment of the present invention provides a method for establishing a neighboring cell relationship, which specifically includes the following steps:

step 181: receiving a first measurement configuration message sent by a first base station and used for indicating a terminal to perform periodic neighbor cell measurement.

Step 182: and after periodic neighbor cell measurement is carried out according to the first measurement configuration message, a measurement result is obtained and reported to the first base station, so that the first base station determines a target cell according to the measurement result.

Step 183: and receiving a second measurement configuration message which is sent by the first base station and indicates the terminal to report the CGI information of a target cell.

Step 184: and acquiring and reporting the CGI information of the target cell according to the second measurement configuration message.

Specifically, the reporting of the CGI information of the target cell to the first base station by the UE specifically includes, but is not limited to, the following scenarios:

when the CGI information reported by the UE includes an NHN-ID and does not include a PSP-ID list, the RRC asn.1 coding structure is as follows, where the NHN-ID is an optional field:

secondly, when the CGI information reported by the UE contains NHN-ID and PSP-ID lists, the RRC ASN.1 coding structure is as follows:

1) when PSP-ID lists in multiple SIBs are reported using the same field,

A) the RRC asn.1 coding structure of CGI information sent by the UE is as follows, where NHN-ID and PSP-ID lists are optional.

B) If the CGI information contains PSP-ID lists for multiple PSP-ID types, the ASN.1 encoding results are as follows, where NHN-ID and three PSP-ID lists are optional.

2) When the PSP-ID lists in multiple SIBs are reported using different fields:

C) the RRC asn.1 coding structure of CGI information sent by the UE is as follows, where NHN-ID and PSP-ID lists are optional.

D) If the CGI information sent by the UE contains PSP-ID lists for various PSP-ID types, the asn.1 coding result is as follows, where NHN-ID and PSP-ID lists are optional.

Wherein, the CGI information of the target cell may further include: part or all service providers broadcasted by the target cell identify the PSP-ID list, but because the time delay for acquiring the PSP-ID list is long, the first measurement reporting indication information can be configured in the second measurement configuration message, and is used for indicating the terminal to acquire and report the NHN-ID in the CGI information of the target cell and the part or all PSP-ID lists broadcasted by the target cell. Further, the first measurement report indication information may also be used to indicate the UE to report a PSP-ID list in the SIB-MF broadcasted by the target cell, a PSP-ID list in the SIBx broadcasted by the target cell, or all PSP-ID lists broadcasted by the target cell. Specifically, the first measurement reporting indication information may be a measurement reporting indication field newly added in a measurement object IE or a measurement report configuration IE of the second measurement configuration message by the first base station, or any field in an existing measurement configuration message, and is used to instruct the UE to read and report a PSP-ID list in a target cell broadcast when reporting CGI information of the target cell. For example, the first measurement reporting indication information is a si-RequestForHO field in a measurement report configuration IE in the second measurement configuration message, and is used for reading and reporting a PSP-ID list in a target cell broadcast when the UE reports the CGI information of the target cell, and the si-RequestForHO field is not set and is used for indicating the UE not to report the broadcast PSP-ID list of the target cell.

Further, when the UE reads the CGI information of the target cell, the CGI information may be read (without interrupting communication with the current serving cell) in any IDLE (IDLE) state, or a time Gap (Gap) for reading the CGI information of the cell may be autonomously controlled, and when the UE autonomously controls reading the Gap of the CGI information, the UE in a CONNECTED (CONNECTED) state may temporarily interrupt communication with the current serving cell, and resume communication with the current serving cell after reading the CGI information. Wherein the second measurement configuration message comprises: and the second measurement reporting indication information is used for indicating the terminal to autonomously control the time gap for acquiring the CGI information of the target cell. For example: the second measurement reporting indication information is a si-RequestForHO field in the measurement report configuration IE in the second measurement configuration message, the si-RequestForHO field is set to indicate that the UE autonomously controls to read the Gap of the CGI information, and the si-RequestForHO field is not set to indicate that the UE reads the CGI information in any IDLE (IDLE) state or autonomously controls to read the Gap of the CGI information.

Step 185: and receiving a third measurement configuration message sent by the first base station to indicate the terminal to report part or all of the PSP-ID list broadcasted by the target cell.

Step 186: and acquiring a PSP-ID list broadcasted by the target cell according to the third measurement configuration message.

Step 187: and carrying the PSP-ID list in a PSP information field of the information element and sending the PSP-ID list to the first base station.

Wherein the third measurement configuration information includes: and the third measurement reporting indication information is used for indicating the terminal to report a part of or all PSP-ID lists broadcasted by the target cell. The third measurement reporting indication information may be a measurement reporting indication field newly added in a measurement object IE or a measurement report configuration IE of the third measurement configuration by the first base station, or any field in an existing measurement configuration message, and is used to indicate the UE to report the PSP-ID list broadcasted by the target cell. For example, the third measurement reporting indication information is an enumeration type reportPSP-ID of a measurement destination (purpose) field newly added in the measurement configuration IE of the measurement configuration message, and is used to indicate the UE to report the broadcast PSP-ID list of the target cell. Specifically, after receiving the measurement configuration message carrying the measurement destination field set as the reportPSP-ID, the UE reads the broadcast PSP-ID list of the target cell and sends the broadcast PSP-ID list to the base station. Specifically, a PSP information field (PSP-Info) is added to the E-UTRAN measurement result IE of the measurement result message, and the UE transmits the broadcast PSP-ID list of the target cell in the PSP-Info field. Wherein, the ASN.1 coding structure of the PSP-Info field can be any one of the following coding structures:

coding one:

and (2) encoding:

coding three:

and (4) encoding:

further, the third measurement configuration information includes: and the fourth measurement reporting indication information is used for indicating the terminal to report the specified PSP-ID list broadcasted by the target cell. I.e. instructs the UE to report a different list of broadcast PSP-IDs. Specifically, the fourth measurement reporting indication information may be a measurement reporting indication field newly added by the first base station in a measurement object IE or a measurement report configuration IE configured by the third measurement, and the fourth measurement reporting indication information may be used to indicate the UE to report a PSP-ID list in an SIB-MF broadcasted by the target cell, a PSP-ID list in an SIBx broadcasted by the target cell, or all PSP-ID lists broadcasted by the target cell.
