Description

Method, device and system for reporting measurement results of group user group cells

technical field

The present invention relates to the field of communication technology, in particular to a method, device and system for reporting measurement results of a closed subscriber group (CSG) cell.

Background technique

In order to perform switching and power control, the terminal needs to measure the wireless link. The terminal measures the signal level quality of neighboring cells and reports the measurement results to the network in the measurement report, and the network can switch the terminal to a cell with better signal to ensure that the current voice service can be used in the new cell. In the cell, better call quality or more favorable call rates can be obtained, and user satisfaction with services can be improved. Fig. 1 is a basic flowchart of measurement result reporting and switching in the prior art.

FIG. 2 is a format diagram of a measurement report reported by a terminal in the GSM circuit domain in the prior art. The main fields and their meanings of the measurement report in Figure 2 are: RXLEV-NCELL (6bit) indicates the measurement result of the signal level of the neighboring cell; BCCH-FREQ-NCELL (5bit) indicates the index of the frequency point of the GERAN neighboring The system message of the serving cell can broadcast the frequency point information of up to 32 GERAN neighboring cells. The 32 frequency point information is represented by the frequency point index (the value range is 0 to 31), and the reported measurement can be indicated by the frequency point index. The result is the measurement result of which frequency point; BSIC-NCELL (6bit) indicates the base station identification code of the neighboring cell. In the system message of the current serving cell, not only the frequency point information of the neighboring cell will be broadcast, but also the base station identification code of the neighboring cell will be broadcast. , there can be multiple base station identification codes under the same frequency point, and a neighboring cell can be uniquely identified through the frequency point index and the base station identification code. In the prior art, the measurement result of one GERAN cell needs to occupy 17 bits of message space, and one measurement report can report the measurement results of six GERAN neighboring cells at most.

Due to the continuous deployment of new access technologies in the existing network, UTRAN cells and/or EUTRAN cells appear around GERAN cells. At this time, the GERAN cell needs to support handover of the terminal to a neighboring cell of other access technologies to meet service requirements.

When there are UTRAN cells around the GERAN cell: broadcast UTRAN neighbor cell information in the system message of the currently serving GERAN cell, including frequency point and scrambling code information, and the terminal establishes a 3G neighbor cell list with a maximum length of 64 through the UTRAN neighbor cell information. That is, a maximum of 64 UTRAN neighboring cells are identified through the neighboring cell indexes of 0-63. In order to include the measurement results of UTRAN neighboring cells in the measurement report, the prior art extends the measurement report as follows to support reporting the measurement results of UTRAN neighboring cells:

When the number of frequency points in the GSM neighboring cell is less than 32, the value range of the frequency point index of the GSM cell in BCCH-FREQ-NCELL is 0 to 30, and the UTRAN is reported by setting BCCH-FREQ-NCELL to 31 The measurement result of the neighbor cell, and fill in the neighbor cell index of the UTRAN neighbor cell to be reported in the 3G neighbor cell list at the BSIC-NCELL to identify which UTRAN neighbor cell is reported.

When there are EUTRAN cells around the GERAN cell: In the system message of the currently serving GERAN cell, only the frequency point information of the EUTRAN neighboring cell will be broadcast, and the physical cell identification information similar to the scrambling code will not be broadcast, but a EUTRAN cell must be uniquely identified Frequency point and physical cell identification information are required, so the terminal cannot establish an EUTRAN neighbor list accurate to the cell level. In order to report the measurement results of EUTRAN neighboring cells, the prior art extends the measurement report as follows to support reporting the measurement results of EUTRAN neighboring cells:

In the prior art, BCCH-FREQ-NCELL uses a value of 0 to 31 to indicate the frequency point information of 32 neighboring cells, and the value of BCCH-FREQ-NCELL to represent UTRAN neighboring cells is 31. Therefore, the frequency point information of GERAN neighboring cells The frequency point information of neighboring cells of EUTRAN can only occupy the value 0~30 of BCCH-FREQ-NCELL. Assuming that "number of frequency points of GSM neighboring cells + number of frequency points of EUTRAN neighboring cells" is equal to 31, then the value range of frequency point indication of EUTRAN neighboring cells is "31-number of frequency points of EUTRAN neighboring cells"~30. For example, if the number of frequency points of GERAN neighboring cells is 29, and the number of frequency points of EUTRAN neighboring cells is 2, then the frequency index of GERAN neighboring cells ranges from 0 to 28, and the value of frequency point indication of EUTRAN neighboring cells ranges from 29 to 30.

In the prior art, the measurement results of EUTRAN neighboring cells are reported by setting BCCH-FREQ-NCELL as the frequency indication of EUTRAN neighboring cells, and the last 3 bits of RXLEV-NCELL and the 6 bits of BSIC-NCELL (total 9 bits) are filled to be reported. The physical cell identifier of the EUTRAN neighbor cell (the identifier is obtained by the terminal itself) identifies which EUTRAN neighbor cell is reported, and the first 3 bits of the RXLEV-NCELL are used to report the measurement result.

Another type of cell in the prior art is a CSG cell, including a UTRAN CSG cell and an EUTRAN CSG cell, both types of cells can become neighboring cells of a GERAN serving cell. However, the existing technology cannot use the measurement report to report the measurement results of the UTRAN CSG and EUTRAN CSG neighboring cells.

Detailed ways

Embodiments of the present invention provide a method, device and system for reporting measurement results of a CSG cell. Since the CSG cell allows the reuse of the physical cell ID, that is, two different UTRAN CSG cells at the same frequency point can use the same PSC (physical scrambling code information); similarly, two EUTRAN CSG cells at the same frequency point can also use the same PSC PCI (Physical Cell Identity). In this way, the frequency point and the PSC/PCI cannot uniquely identify a CSG cell. To uniquely identify a CSG, GCI (Global Cell Id) must be used. The GCI of UTRAN CSG is expressed as GCI-UTRAN, and the GCI of EUTRAN CSG is expressed as GCI-EUTRAN, and the GCI is 28bit.

It takes 28 bits to identify a CSG cell, but the bit space for reporting a GERAN neighbor cell in the measurement report is 17 bits. Originally, the message space for reporting a GERAN neighbor cell cannot report the measurement result of a CSG cell. In order to report the CSG measurement result in the measurement report, the embodiment of the present invention modifies and extends the measurement report of the prior art, so that the terminal reports the measurement result of the CSG neighboring cell, so that the network can handover the terminal to the target CSG cell .

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Example 1:

This embodiment provides a method for reporting measurement results of a group user group cell. FIG. 3 is a flow chart of the implementation method of this embodiment. As shown in Figure 4:

Step S301, measure the signal quality of the group user group cell, and obtain the measurement result;

Step S302, generating a measurement report including the measurement results of the group user group cells, the measurement results including the global cell identities of the group user group cells;

Step S303, sending the measurement report to the network side.

In this embodiment, the measurement result of one CSG cell is reported using the message space for reporting the measurement results of two GERAN neighboring cells in the measurement report of the prior art. In order to be compatible with the reporting of measurement results for UTRAN and EUTRAN in the prior art, this embodiment performs the following extensions on the measurement report of the prior art (Figure 4 is the extended measurement report message format):

Set a value in the BCCH-FREQ-NCELL (Neighborhood Broadcast Control Channel Frequency Point Index) field of the first GERAN cell measurement result as an indication of the group user group cell, which is different from the indication of the UTRAN cell and the GERAN cell The frequency point index and the frequency point indication of the EUTRAN cell; in the 5 bits of the RXLEV-NCELL (neighboring cell reception level) field of the first GERAN cell measurement result, the BSIC-NCELL (neighboring cell base station) of the first GERAN cell measurement result 6 bits of the field and all 17 bits of the message space of the second GERAN cell measurement result are filled with the GCI of the group user group cell; optionally, the RXLEV-NCELL of the first GERAN cell measurement result can also be filled The remaining 1 bit of the field is filled with the measured signal level value of the group user group cell.

When the "Number of frequencies in GSM neighboring cells + the number of frequencies in neighboring cells in EUTRAN" is less than or equal to 30, set BCCH-FREQ-NCELL to "30-Number of frequencies in neighboring cells in EUTRAN" to indicate the number of CSG reports measurement results. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 31 in BCCH-FREQ-NCELL is set as the indication of UTRAN, the value 29~30 is set as the frequency point indication of EUTRAN, and the value 28 is set as the indication of CSG .

Optionally, in this embodiment, the remaining 1 bit in the RXLEV-NCELL is used to indicate the signal level measurement value of the CSG neighboring cell, and 0 and 1 are used to indicate two different levels of signal level values. For example, two threshold values may be set to specifically indicate the size of the measured value. If the measured value exceeds threshold 1 and is lower than threshold 2, then report RXLEV-NCELL as 0, and if the measured value exceeds threshold 2, report RXLEV-NCELL as 1. These two thresholds can be agreed in advance between the network and the terminal, or can be notified by the network to the terminal through a control message; or only when the cell signal strength is the strongest on the frequency point and/or when access is allowed, it is reported. Because in this way, the problem of interference does not need to be considered, and the network side knows that all the CSG cells that the terminal reports are the strongest after sorting the signals and that the terminal can access.

Optionally, in this embodiment, when the measured signal strength of the group user group cell is greater than a set threshold, the measurement report is sent to the network side; or when the measured signal strength of the group user group cell is the same When the frequency point is the strongest, the measurement report is sent to the network.

Embodiment two:

This embodiment provides a method for reporting a measurement result of a group user group cell. Refer to FIG. 3 for a flowchart of the method in this embodiment. Different from Embodiment 1, this embodiment uses the message space for reporting the measurement results of three GERAN neighboring cells in the measurement report of the prior art to report the measurement result of one CSG cell. In order to be compatible with the reporting of measurement results for UTRAN and EUTRAN in the prior art, this embodiment performs the following extensions on the measurement report of the prior art (Figure 5 is the extended measurement report message format):

Set a value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as an indication of the group user group cell, which is different from the indication of the UTRAN cell, the frequency point index of the GERAN cell, and the frequency point indication of the EUTRAN cell ; Fill the 6 bits of the RXLEV-NCELL field of the first GERAN cell measurement result with the signal level value of the measured group user group cell; the BSIC-NCELL field of the first GERAN cell measurement result and the subsequent two GERAN cells In the message space of the measurement result, 28 bits are selected to fill in the global cell identity of the group user group cell.

When the "Number of GSM adjacent cell frequencies + the number of EUTRAN adjacent cell frequency points" is less than or equal to 30, you can set the BCCH-FREQ-NCELL of the first measurement result to "30-EUTRAN adjacent cell frequency points" "Number" to indicate the measurement results of the CSG to be reported. The 6-bit RXLEV-NCELL of the first measurement result is still used to report the measurement result of the cell. Optionally, specific bits may be extracted from the BSIC-NCELL of the first measurement result and the message spaces of the subsequent two measurement results as indications of cell access technology types and/or indications of cell access types. For example, 1 bit is used to indicate whether it is a UTRAN CSG cell or an EUTRAN CSG cell, and 2 bits are used to indicate that the reported cell is a CSG cell that is allowed to be accessed, a CSG cell that is not allowed to be accessed, or a hybrid access cell. The remaining space is filled with 28 bits of GCI. The last unused space is regarded as invalid space, and the bits in these positions have no actual specific meaning.

Embodiment three:

This embodiment provides a method for reporting a measurement result of a group user group cell. Refer to FIG. 3 for a flowchart of the method in this embodiment. The difference from Embodiments 1 and 2 is that this embodiment extends the measurement report to support different types of access networks. Since the 28-bit GCI-UTRAN and GCI-EUTRAN may be exactly the same, in this case, the BSS cannot distinguish the CSG cell under which access technology the reported measurement result is. In order to distinguish CSG cells with two different access technologies in the measurement report, this embodiment adds access network type identification information to the reported measurement results to indicate whether the reported measurement results are UTRAN CSG cells or EUTRAN CSG cells .

Optionally, this embodiment may also extend the measurement report to support different access modes. The access methods of CSG cells are divided into: allowed access (subscribed), not allowed access (unsubscribed), and optionally mixed access, hybrid access can be used as a separate access method, or can be Incorporate into allow access or disallow access. Among them, a hybrid access (Hybrid) cell means that users who subscribe to this cell use this cell as a CSG cell, and users who do not subscribe to this cell can also access this cell, but the services that can be enjoyed in this cell are compared with those of subscribed users. be relatively limited. If the CSG signal strength that is not allowed to be accessed is very high, it will affect the terminal's access to the CSG cell that is allowed to be accessed. In this way, the terminal needs to notify the network of the measurement results of the CSG cell that is not allowed to be accessed, and assist the network to make changes. Appropriate switching decisions.

The following methods can be used to report the access mode in this embodiment: When it is necessary to separately distinguish hybrid access, the reported access mode can include: access allowed, access not allowed, and hybrid access. Any two or all three; when there is no need to distinguish hybrid access separately, the reported access methods may include: allow access and/or not allow access, and combine hybrid access into allow access or not allow access into, without separate distinction.

When using the message space of the measurement results of two GERAN neighboring cells in Embodiment 1 to report the measurement results of one CSG cell, this embodiment adds an access mode identifier to the reported measurement results to indicate different access modes, Specifically include:

(1) Set at least one value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as the network type identifier of the group user group cell, and the value is different from the indication of the UTRAN cell, the frequency point index of the GERAN cell, The frequency indication of the EUTRAN cell; or

(2) Set at least one value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as the access mode identifier of the group user group cell, and the value is different from the indication of the UTRAN cell and the frequency point index of the GERAN cell , the frequency indication of the EUTRAN cell; or

(3) Set at least one value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result to indicate the network type and access mode at the same time. The set value is different from the indication of the UTRAN cell, the frequency point index of the GERAN cell, The frequency indication of the EUTRAN cell; or

(4) When the remaining 1 bit of the RXLEV-NCELL is not used to report the level value, this embodiment may also use the remaining 1 bit of the RXLEV-NCELL to distinguish the type of access network or the access mode of the cell.

In the above four cases of this embodiment, (1) and (4) can be used in combination, and (2) and (4) can also be used in combination, so that the measurement result of the CSG cell includes both the access network type and the cell access method.

The following describes in detail the identification methods of several types of access networks and access methods:

(1) Use 5bit BCCH-FREQ-NCELL to distinguish access network types:

Use 5bit BCCH-FREQ-NCELL to distinguish two kinds of CSG cells. When the "Number of GSM adjacent cell frequencies + the number of EUTRAN adjacent cell frequency points" is less than or equal to 30, set BCCH-FREQ-NCELL to "30-EUTRAN adjacent cell frequency points" and "29-EUTRAN "Number of adjacent cell frequencies" to report the measurement results of UTRAN CSG and EUTRAN CSG cells respectively. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 31 in BCCH-FREQ-NCELL is set as the indication of UTRAN, the value 29~30 is the frequency point index of EUTRAN, and the value 28 is the indication of UTRAN CSG, The value 27 is the indication of EUTRAN CSG.

(2) Use 5bit BCCH-FREQ-NCELL to distinguish different access methods:

Use 5bit BCCH-FREQ-NCELL to distinguish multiple access methods of users: When the "Number of frequency points of GSM neighboring cells + the number of frequency points of neighboring cells of EUTRAN" is less than or equal to 30, set BCCH-FREQ-NCELL "Number of frequency points of adjacent cells of 30-EUTRAN", "Number of frequency points of adjacent cells of 29-EUTRAN" and "Number of frequency points of adjacent cells of 28-EUTRAN" respectively indicate allowed access and not allowed access and hybrid access. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 31 in BCCH-FREQ-NCELL is set as the indication of UTRAN, the value 29~30 is the frequency point index of EUTRAN, and the value 28 indicates that the access is allowed. A value of 27 means access is not allowed, and a value of 26 means mixed access. Optionally, the hybrid access cell may also be classified into a category that allows access or a category that does not allow access.

(3) Use 5-bit BCCH-FREQ-NCELL to distinguish the access network type and different access modes of the cell.

If only the cells that are allowed to be accessed are considered, set BCCH-FREQ-NCELL to "30-Number of adjacent cell frequencies of EUTRAN" to indicate the UTRAN CSG cells that are allowed to be accessed; set BCCH-FREQ-NCELL to "29- "Number of frequency points of adjacent cells in EUTRAN" indicates the EUTRAN CSG cells that are allowed to be accessed. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 31 in BCCH-FREQ-NCELL is set as the indication of UTRAN, the value 29~30 is the frequency point index of EUTRAN, and the value 28 is the one that indicates the access is allowed UTRAN CSG cell, the value 27 indicates the EUTRAN CSG cell that is allowed to be accessed.

If it is also necessary to consider the cells that are not allowed to be accessed, set BCCH-FREQ-NCELL to "28 - the number of adjacent cell frequency points of EUTRAN" to indicate the UTRAN CSG cells that are not allowed to be accessed; then set BCCH-FREQ-NCELL to "27-Number of adjacent cell frequency points of EUTRAN" indicates EUTRAN CSG cells that are not allowed to be accessed. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 26 in BCCH-FREQ-NCELL indicates the UTRAN CSG cell that is not allowed to be accessed, and the value 25 indicates the EUTRAN CSG cell that is not allowed to be accessed.

Hybrid access cells can be classified into the category of cells that are allowed to access, that is, the above "30-EUTRAN adjacent cell frequency points" or "29-EUTRAN adjacent cell frequency points", or can be classified as not allowed The type of cell to access. If mixed access cells are divided into one category, BCCH-FREQ-NCELL can be set to "26 - the number of adjacent cell frequency points of EUTRAN" to indicate mixed access UTRAN cells; set BCCH-FREQ-NCELL to "25 -Number of frequency points of neighboring cells of EUTRAN" means EUTRAN cells with hybrid access. Assuming that the number of adjacent cell frequency points of EUTRAN is 2, the value 24 in BCCH-FREQ-NCELL indicates the UTRAN cell for hybrid access, and the value 23 indicates the EUTRAN cell for hybrid access.

(4) The remaining 1 bit of the RXLEV-NCELL is used to distinguish two types of access networks. For example, setting it to 0 means it is a UTRAN CSG cell, and setting it to 1 means it is an EUTRAN CSG cell. In this way, the measurement report has no bit space to report the measurement results. Optionally, a threshold value may be set, and the terminal reports the measurement result of the CSG cell only when the measured level value of the neighboring cell is higher than the threshold value. The threshold value can be agreed between the network and the terminal in advance, or can be notified by the network to the terminal through a control message; or it can be reported only when the cell signal strength is the strongest on the frequency point and/or when access is allowed, because in this way There is no need to consider the problem of interference. The network side knows that all the CSG cells reported by the terminal are the CSG cells with the strongest signal after ranking and the terminal can access.

(5) The remaining 1 bit of RXLEV-NCELL is used to distinguish different access modes of users. For example, the three access methods are divided into two categories (mixed access cells are classified into the category allowed for access), and 0 and 1 are used to distinguish these two categories.

When using the message space of the measurement results of three GERAN neighbor cells in Embodiment 2 to report the measurement result of one CSG cell, specific bits can be extracted from the remaining message space as the indication of the cell access technology type and/or cell permission Indication of access type. For example, use 1 bit to indicate whether it is a UTRAN CSG cell or an EUTRAN CSG cell, and use 2 bits to indicate the CSG cell that is allowed to be accessed, the CSG cell that is not allowed to be accessed, or the mixed access cell.

In this embodiment, the network type indication and/or user access mode of the group user group cells that need to be reported are determined through an agreement with the network side; or the group users that need to be reported are determined according to the notification issued by the network side Indicates the network type of the group cell and/or the access mode of the user. The specific reporting strategy can be a combination of one or more of the following sub-strategies: a. The terminal reports/does not report the access technology type of the cell; b. The terminal reports/does not report the type of the access cell; c. The terminal reports/does not report Cells that are not allowed to be accessed; d. The terminal reports/does not report the hybrid access cell; e. The terminal reports the hybrid access cell as/not as a cell that is allowed to be accessed.
