Description

Technical field

The present invention relates to the field of communication technologies, and in particular, to a method, device and system for reporting a measurement result of a Closed Subscriber Group (CSG) cell.

Background technique

In order to perform handover and power control, the terminal needs to measure the wireless link. The terminal measures the signal level quality of the neighboring cell, and reports the measured result to the network in the measurement report, and the network can switch the terminal to the cell with better signal to ensure that the current voice service can be new. Get better call quality or more favorable call rates in the cell, and improve user satisfaction with the business. FIG. 1 is a basic flow chart of reporting and switching of measurement results in the prior art.

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

As new access technologies are continuously deployed in the live network, UTRAN cells and/or EUTRAN cells appear around the GERAN cell. At this time, the GERAN cell needs to support the handover of the terminal to the neighboring area of other access technologies to meet the needs of the service.

When a UTRAN cell exists around the GERAN cell: broadcast UTRAN neighbor information, including frequency and scrambling code information, in the system message of the currently serving GERAN cell, and the terminal passes The UTRAN neighboring cell information establishes a 3G neighboring cell list with a maximum length of 64, that is, a maximum of 64 UTRAN neighboring cells are identified by a neighboring cell index of 0 to 63. In order to be able to include the measurement result of the UT AN neighbor in the measurement report, the prior art extends the measurement report to support the measurement result of reporting the UTRAN neighbor cell:

When the number of frequency points in the GSM neighboring area is less than 32, then in BCCH-FREQ-NCELL

The frequency index of the GSM cell ranges from 0 to 30. The UTCH-FREQ-NCELL is set to 31 to indicate the measurement result of the UTRAN neighbor, and the BSIC-NCELL is filled with the UTRAN neighbor to be reported in the 3G neighbor. The neighboring cell index in the zone list identifies which UTRAN neighboring zone is reported.

When there is an EUTRAN cell around the GERAN cell, only the frequency information of the EUTRAN neighboring cell is broadcasted in the system message of the currently serving GERAN cell, and the physical cell identification information similar to the scrambling code is not broadcasted, but an EUTRAN cell is uniquely identified. The frequency point and physical cell identification information are needed, so the terminal cannot establish an EUTRAN neighbor list that is accurate to the cell level. In order to report the measurement result of the EUTRAN neighboring cell, the prior art extends the measurement report as follows to support the measurement result of the EUTRAN neighbor cell:

In the prior art, the BCCH-FREQ-NCELL uses the value of 0-31 to represent the frequency point information of 32 neighboring cells, and the BCCH-FREQ-NCELL takes the value 31 to represent the UTRAN neighboring cell. Therefore, the frequency information of the GERAN neighboring cell The frequency information of the neighboring area of EUTRAN can only occupy the value of BCCH-FREQ-NCELL from 0 to 30. Assume that the number of frequency points in the GSM neighboring cell + the number of frequency points in the EUTRAN neighboring cell is equal to 31. In this case, the value range of the EUTRAN neighboring cell frequency point is "31 - EUTRAN neighboring cell frequency point" ~ 30. For example, the number of frequency points of the GERAN neighboring cell is 29, and the number of frequency points of the EUTRAN neighboring area is 2. The frequency index of the GERAN neighboring cell is 0-28, and the frequency of the EUTRAN neighboring cell is 29~. 30.

The prior art reports the measurement result of the EUTRAN neighbor by setting the BCCH-FREQ-NCELL to the EUTRAN neighbor frequency indication, and fills the report in the last 3 bit part of the RXLEV-NCELL and the 6 bit (9 bit total) of the BSIC-NCELL. Physical area of the EUTRAN neighbor The identifier (which is obtained by the terminal itself) identifies which EUTRAN neighbor is reported, and the first 3 bits of the RXLEV-NCELL are used to report the measurement result.

There is also a cell in the prior art that is a CSG cell, including a UTRAN CSG cell and an EUTRAN CSG cell, both of which can be neighbors of the GERAN serving cell. However, the prior art cannot report the measurement results of the UTRAN CSG and EUTRAN CSG neighbors using the measurement report.

detailed description

The embodiment of the invention provides a method, a device and a system for reporting a measurement result of a CSG cell. Since the CSG cell allows reuse of the physical cell identity, that is, two different UTRAN CSG cells of the same frequency point can use the same PSC (physical scrambling code information); likewise, two EUTRAN CSG cells of the same frequency point can also use the same PCI (physical cell identity). Thus, the frequency point and PSC/PCI cannot uniquely identify a CSG cell. To uniquely identify a CSG, use GCI (Global Cell Id), GCI representation of UTRAN CSG. For GCI-UTRAN, the GCI of the EUTRAN CSG is denoted as GCI-EUTRAN, and the GCI is 28 bits.

To identify a CSG cell, it is 28 bits, and the bit space of a GERAN neighboring cell reported in the measurement report is 17 bits. The message space originally reported in a GERAN neighbor cannot report the measurement result of a CSG cell. In order to implement the measurement result of the CSG in the measurement report, the embodiment of the present invention modifies and expands the measurement report of the prior art to implement the measurement result reported by the terminal to the CSG neighboring cell, so that the network can switch the terminal to the target CSG cell. .

The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

This embodiment provides a method for reporting a measurement result of a group user group cell. FIG. 3 is a flowchart of an implementation method of the embodiment. As shown in Figure 4:

Step S301: Measure a signal quality of a group user group cell, and obtain a measurement result. Step S302: Generate a measurement report that includes a measurement result of the group user group cell, where the measurement result includes a global cell identifier of the group user group cell;

Step S303: Send the measurement report to the network side.

This embodiment reports the measurement result of a CSG cell by using a message space in which the measurement results of the two GERAN neighbors are reported in the measurement report of the prior art. In order to be compatible with the measurement results reported by the prior art for UTRAN and EUTRAN, this embodiment extends the following measurement reports of the prior art (Fig. 4 is an extended measurement report message format):

Setting a value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as an indication of the group user group cell, the value being different from the indication of the UTRAN cell, the GERAN cell Frequency point index and frequency indication of the EUTRAN cell; 5 bits of the RXLEV-NCELL (neighboring reception level) field of the first GERAN cell measurement result, BSIC-NCELL (neighborhood base station) of the first GERAN cell measurement result 6 bits of the ID field and the second GERAN cell measurement result The GCI of the group user group cell is filled in all the 17-bit message spaces; optionally, the measured signal of the group user group cell may be filled in the remaining 1 bit of the RXLEV-NCELL field of the first GERAN cell measurement result. Level value.

When "the number of GSM neighbors + the number of neighbors of EUTRAN" is less than or equal to 30, set BCCH-F EQ-NCELL to "30 - EUTRAN's neighbor frequency" to indicate the CSG is reported. Measurement results. Assume that the number of neighboring frequency points of EUTRAN is 2, the value 31 in the Bay U BCCH-FREQ-NCELL is set to the indication of UTRAN, the value 29~30 is set to the frequency indication of EUTRAN, and the value 28 is set to CSG. Instructions.

Optionally, in this embodiment, the remaining lbit in the RXLEV-NCELL is used to indicate the signal level measurement value of the CSG neighbor, and the signal level values of the two different levels are indicated by 0 and 1. For example, the size of the measured value can be specifically indicated by setting two threshold values. If the measured value exceeds the threshold value 1 and is lower than the threshold value 2, the RXLEV-NCELL is reported as 0. If the measured value exceeds the threshold value 2, the RXLEV-NCELL is reported as 1. The two thresholds may be agreed by the network and the terminal in advance, or may be notified to the terminal by the network through a control message; or only when the cell signal strength is the strongest at the frequency and/or allowed to access, Because this does not need to consider the interference problem, the network side knows that the terminal reports the CSG cell that is the strongest after the signal sorting and 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 is the strongest, the measurement report is sent to the network.

Embodiment 2: This embodiment provides a method for reporting a measurement result of a group user group cell. The flowchart of the method in this embodiment refers to FIG. 3. Different from the first embodiment, the present embodiment reports a measurement result of a CSG cell by using a message space in which three GERAN neighboring cell measurement results are reported in the measurement report of the prior art. In order to be compatible with the measurement results of the UTRAN and the EUTRAN in the prior art, this embodiment extends the following measurement report of the prior art (FIG. 5 is an extended measurement report message). Format

Setting a value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as an indication of the group user group cell, the value being 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. Filling the measured signal level value of the group user group cell in 6 bits of the RXLEV-NCELL field of the first GERAN cell measurement result; the BSIC-NCELL field of the first GERAN cell measurement result and the subsequent two GERAN cells The 28 bits of the message space of the measurement result are selected to fill the global cell identity of the group user group cell.

When "the number of GSM neighbors + the number of neighbors of EUTRAN" is less than or equal to 30, the BCCH-FREQ-NCELL of the first measurement result can be set to "30 - EUTRAN neighbor frequency The number "to indicate the measurement result of the CSG. The 6-bit RXLEV-NCELL of the first measurement is still used to report the measurement results of the cell. Optionally, in the message space of the BSIC-NCELL and the subsequent two measurement results of the first measurement result, the specific bit may be extracted as an indication of the type of the cell access technology and/or an indication of the type of the cell allowed access. If the lbit indication is a UTRAN CSG cell or an EUTRAN CSG cell, the cell that is reported to be reported by using 2 bits is a CSG cell that is allowed to access, and a CSG cell or a hybrid access cell that is not allowed to access. The remaining space uses 28 bits to fill the GCI. The last unused space is the invalid space, and the bits in these locations have no actual meaning. Embodiment 3:

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

Optionally, the embodiment may further extend the measurement report to support different access modes. The access modes of the CSG cell are divided into: access allowed (signed), not allowed (unsigned), optionally including hybrid access, and hybrid access can be used as a separate access mode. Inclusion allows access or does not allow access. The hybrid access (Hybrid) cell refers to: the user who subscribes to the cell uses the cell as a CSG cell, and the user who does not sign the cell can also access the cell, but only the service that can be enjoyed in the cell is compared to the subscribed user. To be relatively limited. If the CSG signal strength that is not allowed to be accessed is high, the terminal accesses the CSG cell that is allowed to access, so that the terminal needs to notify the network of the measurement result of the CSG cell that is not allowed to access, and the auxiliary network makes more A suitable handover decision.

The reporting manner of the access mode in this embodiment may be as follows: When the hybrid access needs to be separately distinguished, the reported access mode may include: access, no access, and hybrid access. Any two or all three types; when the hybrid access is not separately distinguished, the reported access mode may include: allowing access and/or disallowing access, and incorporating the hybrid access into the allowed intervention or not allowing access Into, without distinguishing separately.

When the measurement result of a CSG cell is reported in the message space of the two GERAN neighboring cell measurement results of Embodiment 1, the embodiment adds an access mode identifier to the reported measurement result to indicate different access modes. Specifically include:

(1) setting 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, the value is different from

The indication of the UTRAN cell, the frequency index of the GERAN cell, the frequency indication of the EUTRAN cell or

(2) setting at least one value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result as an access mode identifier of the group user group cell, the value being different from the indication of the UTRAN cell, and the frequency index of the GERAN cell. , the frequency point of the EUTRAN cell (3) setting at least one value in the BCCH-FREQ-NCELL field of the first GERAN cell measurement result, indicating the network type and the access mode, the set value is different from the indication of the UTRAN cell, the frequency index of the GERAN cell, The frequency indication of the EUTRAN cell 5 or

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

In the above four cases of this embodiment, (1) and (4) may be used in combination, and (2) and (4) may 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 access network categories and access methods:

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

The 5bit BCCH-FREQ-NCELL is used to distinguish between two CSG cells. When "the number of GSM neighbors + the number of neighbors of EUTRAN" is less than or equal to 30, set BCCH-FREQ-NCELL to "30-EUTRAN's neighbor frequency" and "29-EUTRAN" The number of neighboring cells is reported to report the measurement results of the UTRAN CSG and the EUTRAN CSG cell, respectively. Assume that the number of neighboring frequency points of EUTRAN is 2, the value 31 in the Bayer lj BCCH-FREQ-NCELL is set to the indication of UTRAN, the value 29~30 is the frequency index of EUTRAN, and the value 28 is the indication of UTRAN CSG. The value 27 is an indication of the EUTRAN CSG.

(2) Use 5bit BCCH-FREQ-NCELL to distinguish different access methods: Use 5bit BCCH-FREQ-NCELL to distinguish multiple access modes of users: When "the number of GSM neighbors + EUTRAN neighbors" When the number of regional frequency points is less than or equal to 30, set BCCH-FREQ-NCELL to "30-EUTRAN's neighboring frequency points", "29-EUTRAN's neighboring frequency points", and "28-EUTRAN The number of neighboring cells is "to indicate access, no access, and hybrid access. Assuming that the number of neighboring frequency points of EUTRAN is 2, the value 31 in BCCH-FREQ-NCELL is set to the indication of UTRAN, and the value is 29-30 is the frequency index of the EUTRAN. The value 28 indicates that access is allowed, the value 27 indicates that access is not allowed, and the value 26 indicates hybrid access. Alternatively, the hybrid access cell may also be classified into a category that allows access or a category that is not allowed to access.

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

If only the cell that is allowed to access is considered, the BCCH-FREQ-NCELL is set to "30 - the number of neighbor cells of the EUTRAN" indicates the UTRAN CSG cell that is allowed to access; the BCCH-FREQ-NCELL is set to "29- The number of neighboring cell frequencies of the EUTRAN "represents the EUTRAN CSG cell that is allowed to access. Assuming that the number of neighboring cells in the EUTRAN is 2, the value 31 in the BCCH-FREQ-NCELL is set to the UTRAN indication, and the value 29 to 30 is the frequency index of the EUTRAN, and the value 28 is the access allowed. UTRAN CSG cell, value 27 indicates the EUTRAN CSG cell that is allowed to access.

If it is also necessary to consider the cell that is not allowed to access, set BCCH-FREQ-NCELL to "28-EUTRAN's neighbor cell number" to indicate that the UTRAN CSG cell is not allowed to access; then set BCCH-FREQ-NCELL The "27-EUTRAN neighbor frequency number" indicates an EUTRAN CSG cell that is not allowed to access. Assuming that the number of neighboring cells of the EUTRAN is 2, the value 26 in the BCCH-FREQ-NCELL indicates that the UTRAN CSG cell is not allowed to access, and the value 25 indicates the EUTRAN CSG cell that is not allowed to access.

The hybrid access cell may be classified into the class of the cell that is allowed to access, that is, the above "30-EUTRAN neighbor cell frequency number" or "29-EUTRAN neighbor cell frequency number" may also be classified as not allowed. The cell class to access. If the hybrid access cells are separately classified into one class, the BCCH-FREQ-NCELL may be set to "26-EUTRAN neighbor cell number" to indicate the hybrid access UTRAN cell; BCCH-FREQ-NCELL is set to "25 - The number of neighboring frequency points of the EUTRAN "represents the EUTRAN cell of the hybrid access. It is assumed that the number of neighboring frequency points of the EUTRAN is 2, the value 24 in the Bayesl BCCH-FREQ-NCELL indicates the mixed access UTRAN cell, and the value 23 indicates the mixed access EUTRAN cell. (4) The remaining lbit of RXLEV-NCELL is used to distinguish between two access network categories. For example, a setting of 0 indicates that it is a UTRAN CSG cell, and a setting of 1 indicates an EUTRAN CSG cell. In this way, the measurement report has no bit space to report the measurement results. Optionally, the threshold value is set, and when the measured neighboring cell level value is higher than the threshold, the terminal reports the measurement result of the CSG cell. The threshold may be agreed by the network and the terminal in advance, or may be notified to the terminal by the network through a control message; or reported only when the cell signal strength is the strongest at the frequency and/or allowed to access, because There is no need to consider the problem of interference. The network side knows that the terminal reports the CSG cell that is the strongest after the signal ranking and the terminal can access.

(5) The remaining lbit of RXLEV-NCELL is used to distinguish different access modes of users. For example, the three access modes are divided into two categories (the hybrid access cells are classified into the allowed access categories), and 0 and 1 are used to distinguish the two types.

When the measurement result of one CSG cell is reported in the message space of the three GERAN neighbor measurement results of Embodiment 2, the specific bit may be extracted in the remaining message space as an indication of the type of the cell access technology and/or the cell permission. An indication of the type of access. If the lbit indication is a UTRAN CSG cell or an EUTRAN CSG cell, for example, a CSG cell that is allowed to access by the reported cell using 2 bits, a CSG cell or a hybrid access cell that is not allowed to access.

In this embodiment, the network type indication and/or the access mode of the user of the group user group that needs to be reported are determined by the agreement with the network side; or the group user that needs to be reported is determined according to the notification sent by the network side. The network type indication of the group cell and/or the access mode of the user. The specific reporting policy may be a combination of one or more of the following sub-policies: a. The access technology category of the reporting/non-reporting cell of the terminal; b. The class reported/not reported by the terminal; c. The terminal reports/does not report The cell that is not allowed to access; d. The terminal reports/does not report the hybrid access cell; e. The terminal reports the mixed access cell as/not as the allowed access cell.
