detailed description

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In order to solve the technical problem of the unique identification of the CSG cell, which is also referred to as the HNB cell, the embodiment of the present invention provides a method for globally identifying the CSG cell. FIG. 1 is a CSG cell global identifier according to an embodiment of the present invention. The CSG cell global identifier includes: a Tracking Area (TA) identifier and a cell identifier (Cell 1 ident i ty ), and the CSG cell globally The length L of the identifier is a fixed value (L is the length represented by the binary, that is, the binary number of the L bit, and the length referred to in the following description refers to the length of the binary representation).

The TA identifier is used to identify the CSG, and may also be referred to as a CSG identifier. The cell identifier is used to identify one of the multiple CSG cells in the same CSG. In a practical application, if there is only one CSG cell in a CSG, the CSG cell global identifier may include only the CSG identifier. In this case, the length of the CSG identifier is L, and the CSG identifier is equivalent to the global identifier of the CSG cell; Multiple CSGs For the cell, the number of bits N (N is an integer greater than or equal to zero) of the cell identifier provided by the embodiment of the present invention may be configured according to the number of CSG cells in one CSG, and the number of bits occupied by the CSG identifier is equal to the global identifier of the CSG cell. Length L minus the number of bits occupied by the cell identity Since the number of CSG cells in the CSG varies, the number of bits N occupied by the cell identity is variable. Therefore, the CSG cell global identifier provided by the embodiment of the present invention can flexibly uniquely identify one CSG cell.

Assume that the CSG identifier is 32 bits long. If there are 3 CSG cells in a CSG, the number of bits occupied by the cell identifier is 2, and the CSG identifier occupies 30 bits. If there are 10 CSG cells in the CSG, the cell identifier occupies The number of digits is 4 digits and the CSG logo occupies 28 digits. The foregoing examples are only for the purpose of more clearly illustrating that the CSG cell global identifier of the embodiment of the present invention can uniquely identify a large number of CSG cells, and should not be construed as limiting the embodiments of the present invention.

It should be noted that, if the number of CSG cells is not very large, the number of bits of the CSG identifier and the number of bits of the cell identifier that have been described above may also be set to a fixed value, which does not affect the implementation of the embodiment of the present invention. .

In order to optimize the method for identifying a CSG cell in the mobility related procedure, the embodiment of the present invention further provides a method for constructing a CSG cell list. The CSG cell list is a process in which the mobile terminal registers with the network or performs location update. After the network sends the CSG white list to the mobile terminal, the mobile terminal and the network are respectively constructed according to the CSG white list. The CSG white list includes at least one CSG identifier that the mobile terminal can access, and may further include other information related to the CSG, for example, a frequency point of each cell in the CSG, and a local identifier of the cell (GERAN is a base station identifier, UTRAN) Is the scrambling code, E-UTRAN is the physical cell identifier) and so on.

Referring to FIG. 2, a method for constructing a CSG cell list according to an embodiment of the present invention includes: Step 201: Receive a CSG white list, where the CSG white list includes at least one CSG identifier;

Step 202: If a scenario triggered by the CSG cell list is triggered, the CSG cell list is constructed according to the CSG white list.

In practical applications, the scenario of triggering the construction of the CSG cell list includes but is not limited to, the mobile terminal The CSG white list sent during power-on registration or during the location update process is different from the previous one. The constructing the CSG cell list is specifically: creating an empty CSG cell list, and sequentially processing each CSG identifier in the CSG white list according to the order of the CSG identifier in the CSG white list.

Referring to FIG. 3, a specific implementation process of constructing a CSG cell list according to an embodiment of the present invention includes:

Step 301: Determine whether the length of the CSG identifier is equal to the length of the global identifier of the CSG cell, or is smaller than the length of the global identifier of the CSG cell. If yes, go to step 302, if not, go to step 303;

The determining whether the length of the CSG identifier is equal to the length of the global identifier of the CSG cell or the length of the global identifier of the CSG cell is to determine whether the CSG corresponding to the CSG identifier includes one CSG cell or multiple CSG cells. In other embodiments of the present invention, other methods may be used to determine the number of cells included in the CSG corresponding to the CSG identifier. For example, the CSG cell included in the CSG corresponding to each CSG identifier may be directly given in the CSG white list. The method of determining the number of the information is simpler and will not be described here, and does not affect the implementation of the embodiment of the present invention.

If the length of the CSG identifier is equal to the length of the CSG cell global identifier, it indicates that the CSG corresponding to the CSG identifier includes only one CSG cell, and the CSG identifier is the global identifier of the CSG cell, and the process proceeds to step 302, where the CSG identifier is used as a The CSG cell global identity occupies one entry of the CSG cell list.

If the length of the CSG identifier is smaller than the length of the CSG cell global identifier, the CSG corresponding to the CSG identifier includes multiple CSG cells, and the process proceeds to step 303.

Step 302: Add the CSG identifier to the group user group cell list, and the added content may further include physical parameters of the CSG cell corresponding to the CSG identifier, such as a frequency point and/or a physical cell identifier, and the CSG identifier. And the physical parameters occupy the same index;

Step 303: Obtain a CSG cell global identifier according to the length of the CSG identifier, and add the CSG cell global identifier to the group user group cell list, and the added content may further include the CSG corresponding to the CSG cell global identifier. Physical parameters of the cell, such as frequency and/or physical cell It is known that each CSG cell global identifier and its corresponding physical parameter occupy the same index; wherein, step 303 is performed to obtain a CSG cell global identifier corresponding to all possible CSG cells included in one CSG.

In an actual application, if the length of the CSG identifier is L-N, the following steps may be used to generate a global CSG cell identifier:

Generating two binary cell identifiers of length N (Cell identity);

Two cell identifiers of length N are respectively added to the CSG identifiers that are shifted to the left by N bits, and 2 ^N CSG cell global identifiers of length L are generated.

The CSG cell global identifier is sequentially added to the CSG cell list one by one according to the order of all the possible CSG cell global identifiers in the CSG (for example, the CSG cell global identifier is in the order of small to large). The CSG occupies 2 entries of the CSG cell list.

The specific implementation process of constructing a global identifier of a CSG cell provided by the embodiment of the present invention is described above. In order to explain the embodiment of the present invention more clearly, the following describes the embodiment of the present invention with reference to specific examples.

For example, a CSG white list includes three CSG identifiers, in the order of CSG identifier 1, CSG identifier 2, and CSG identifier 3. The length of the CSG cell global identifier is L. The length of the CSG mark 1 is L - 2, the length of the CSG mark 2 is L, and the length of the CSG mark 3 is L - 1.

If the scenario triggered by the CSG cell list is triggered, an empty CSG cell list is first created, which is named CSG cell list.

Then, according to the order of the CSG logo in the CSG white list, the CSG logo 1 is processed first. The process of processing the CSG logo 1 includes:

If the length L-2 of the CSG identifier 1 is less than L, the number of CSG packets corresponding to the CSG identifier 1 is more than one, that is, the CSG corresponding to the CSG identifier 1 may include up to 2 ² = 4 CSG cells, generating four binaryes. The cell identifiers 00, 01, 10, 11, respectively, add the above four cell identifiers to the CSG identifier 1 that is shifted to the left by N bits, and obtain the CSG packets corresponding to the CSG identifier 1 and all possible CSG cell global identifiers, respectively : CSG ID 1 X 4+00 (CSG ID 1 χ 4 indicates that the CSG ID of the binary representation 1 is shifted to the left 2 bits, 00 means decimal 0), CSG mark 1 X 4+01 (01 means decimal 1), CSG mark 1 X 4+10 (10 means decimal 2), CSG mark 1 x 4+11 (11 means Decimal 3). The CSG identifier 1 X 4+00, the CSG identifier 1 χ 4+01, the CSG identifier 1 x 4+10, and the CSG identifier are sequentially selected according to the CSG cell global identifier of the CSG packet corresponding to the CSG identifier 1 from small to large. 1 x 4+11 is added to the CSG cell list, and the index of the occupied entry is 0, 1, 2, 3.

After processing the CSG logo 1, the CSG logo 2 continues to be processed. The process of processing the CSG Logo 2 includes:

The length of the CSG identifier 2 is L, and the corresponding CSG contains only one CSG cell. If the CSG cell global ID is CSG ID 2, the CSG ID 2 is added to the CSG cell list, and the occupied index is 4.

After processing the CSG logo 2, the CSG logo 3 continues to be processed. The process of processing the CSG Logo 3 includes:

If the CSG identifier 3 is smaller than L, then the CSG identifier 3 corresponds to more than one CSG packet, that is, the corresponding CSG may include up to 2^2 CSG cells, and generate two binary cell identifiers. 0 and 1, the above two cell identifiers are respectively added to the CSG identifier 3 that is shifted to the left by N bits, and all possible CSG cell global identifiers included in the CSG corresponding to the CSG identifier 3 are obtained, respectively: CSG identifier 3 X 2+0 (CSG flag 3 X 2 indicates that the CSG flag 3 of the binary representation is shifted to the left by 1 bit, 0 represents the decimal 0), and the CSG flag is 3 x 2+1 (1 represents the decimal 1). The CSG identifier 3 X 2+0 and the CSG identifier 3 X 2+1 are sequentially added to the CSG cell list according to the CSG packet corresponding to the CSG identifier 3, and all the possible CSG cell global identifiers are sequentially changed from the smallest to the largest. For 5, 6.

In the embodiment of the present invention, the processing sequence of each CSG identifier in the CSG white list may be processed in the order of small to large according to the CSG identifier, in addition to the method described in the foregoing embodiment. Both the network and the mobile terminal construct a CSG cell list in the same way.

In the embodiment of the present invention, each CSG cell global identifier in the CSG cell list corresponds to one CSG cell list index, and the length of the index is generally not large. For example, an index of length 6 can correspond to 64 CSG cell global identifiers. This is relative to the CSG cell global identity, such as 32-bit identification of a CSG The community can save 26 places. Therefore, in the communication process, the index of the CSG cell can be optimized by using the index.

After the technical problem of uniquely identifying the CSG cell is solved, the following is a technical problem that the prior art cannot report and identify the CSG cell measurement report. For this reason, the embodiment of the present invention provides a measurement report processing method.

Referring to FIG. 4, a flowchart of a method for processing a measurement report according to an embodiment of the present invention includes: Step 401: A mobile terminal performs measurement on a CSG cell autonomously under network control or a mobile terminal; wherein, the measurement of the CSG cell may be performed by using The same method of measuring the E-URTAN macro cell is not described herein.

Step 402: The mobile terminal reports the measurement report to the base station subsystem, where the measurement report includes: a CSG cell indication, a CSG cell identifier, and a measurement result;

The CSG cell identifier may be a CSG cell global identifier as described above, or may be a CSG cell list index.

In an actual application, if the mobile terminal reports the measurement report of the CSG cell to the base station subsystem through the enhanced measurement, the enhanced measurement report message needs to be added: CSG cell indication, CSG cell Identification (CSG cell global identity or CSG cell list index), measurement results. If the newly defined message is used to report the measurement report of the CSG cell to the base station subsystem, the newly defined message should include: CSG cell indication, CSG cell identity (CSG cell global identifier or CSG cell list index), and measurement result.

If the base station subsystem does not determine that the measured cell is a CSG cell according to the CSG cell indication, the measurement report may not include: the CSG cell indication, and the base station subsystem performs step 303.

Step 403: The base station subsystem parses the cell identifier from the measurement report. If the cell identifier is the same as the preset CSG cell identifier, the base station subsystem saves and processes the measurement result carried in the measurement report and the CSG cell identifier.

If the base station subsystem does not determine whether the measurement report is a measurement of the CSG cell according to the CSG cell indication, the measurement report needs to include: a CSG cell indication, and the base station subsystem parses The CSG cell indicates that the measurement result is a measurement report of the CSG cell, and the CSG cell identifier is parsed to obtain the measurement results of the CSG cells included in the measurement report, and the measurement result is saved and processed correspondingly to the CSG cell identifier. .

If the CSG cell identifier is the CSG cell global identifier that has been described above, the base station subsystem may save and process the measurement result corresponding to the CSG cell global identifier. If the CSG cell global identifier is the CSG cell list index as described above, The base station subsystem can save and process the measurement result corresponding to the CSG cell list index.

The base station subsystem in the above embodiment is a general term for the BSS (Base Station Subsystem) of the GERAN, the RNS (Radio Network Subsystem) of the UTRAN, and the eNode B (Speaking Base Station) of the E-UTRAN. If in a UTRAN network, the base station subsystem refers to the radio network subsystem; if in the E-UTRAN network, the base station subsystem refers to the lecture base station, the following description uses the same convention.

The foregoing provides a measurement report processing method according to an embodiment of the present invention. Since the method can implement the CSG cell measurement result by the mobile terminal, and the network side can identify the CSG cell measurement result, the mobility management of the mobile terminal can be further implemented. If the target cell is a group user group cell, the group group cell identifier is obtained, and the group user group cell identifier is carried in the mobility management message and sent to the mobile terminal.

In the embodiment of the present invention, the mobility management includes: the mobile terminal performs handover, redirection, cell reselection, and the like from the GERAN/UTRAN/E-UTRAN to the CSG cell.

The following describes a method for a mobile terminal to perform handover, redirection, and cell reselection from a GERAN/UTRAN to a CSG cell according to an embodiment of the present invention. A method flow diagram for switching, the method comprising:

Step 501: The base station subsystem selects a target CSG cell to be switched according to the CSG cell measurement result reported by the mobile terminal.

Step 502: The base station subsystem is based on the CSG cell identifier (CSG cell global identifier or CSG small) The area list index) determines the Home NodeB identifier of the target CSG cell, and may fill the ID of the Home NodeB into a message (such as Handover reques t, PS handover reque st ) sent to the core network.

In this embodiment and other embodiments of the present invention, the function of determining the correspondence between the CSG cell global identifier/CSG cell list index and the Home NodeB identifier may also be implemented by a dedicated functional entity, or may be implemented by the core network.

Step 503: After the Home NodeB of the target CSG cell is ready, the base station subsystem carries the target CSG cell identifier in a handover message (such as an In ter-RAT handover) and sends the message to the mobile terminal.

The CSG cell identifier may be a CSG cell global identifier as described above, or may be a CSG cell list index, and the CSG cell identifier may be obtained by the station subsystem from the CSG cell measurement report.

Step 504: After receiving the handover message, the mobile terminal determines the physical parameters of the CSG cell according to the CSG cell identity, and switches to the target CSG cell corresponding to the physical parameter.

FIG. 6 is a flowchart of a method for a mobile terminal to perform redirection in a CSG cell according to an embodiment of the present invention, where the method includes:

Step 601: The base station subsystem selects a retargeted target CSG cell according to the CSG cell measurement result reported by the mobile terminal.

Step 602: The base station subsystem sends a channel translation (eg, Channe l re l ea s e ) message carrying the target CSG cell identifier to the mobile terminal;

Step 603: After receiving the channel release message, the mobile terminal determines the physical parameter of the CSG cell according to the CSG cell identifier, and translates the corresponding channel resource and redirects to the target cell corresponding to the physical parameter. FIG. 7 is a flowchart of a method for cell reselection of a network-controlled mobile terminal according to an embodiment of the present invention, where the method includes:

Step 701: The base station subsystem selects a target CSG cell that is changed by the cell according to the CSG cell measurement result reported by the mobile terminal.

Step 702: The base station subsystem sends a cell change (such as Packet cel change order) message carrying a CSG cell identifier (CSG cell global identifier or CSG cell list index) to the mobile terminal.

Step 703: After receiving the cell change message, the mobile terminal determines the physical parameter of the CSG cell according to the CSG cell identifier, and camps on the CSG cell corresponding to the physical parameter.

In the method for the mobile terminal to perform handover, redirection, and cell reselection from the GERAN/UTRAN to the CSG cell, the mobile terminal may receive the CSG cell global identifier or the CSG cell list index after receiving the message of the CSG cell global index or the CSG cell list index. The CSG cell global identifier or the CSG cell list index is matched with the CSG cell global identifier or the CSG cell list saved by the CSG cell to determine whether the cell identifier carried in the message is a CSG cell identifier. If the mobile terminal does not determine that it is a CSG cell according to the CSG cell indication of the target cell, in the embodiment of the handover, redirection, and network-assisted cell reselection method, the message involved includes the CSG cell identifier when the target cell is a CSG cell. (CSG cell global identity or CSG cell list index) Also, the CSG cell indication should also be included. If the mobile terminal determines that the target cell is a CSG cell, the mobile terminal needs to determine a physical parameter of the target cell according to the CSG cell identifier, where the physical parameter includes at least a frequency point and a physical cell identifier. If the CSG cell identifier is a CSG cell global identifier, the physical parameter of the target cell can be obtained directly through the CSG whi te list; if the CSG cell identifier is a CSG cell list index and the physical parameters of the CSG cell exist in the CSG cell list, the The CSG cell list obtains the target cell physical parameter. If the CSG cell identifier is the CSG cell list index and the CSG cell list does not have the physical parameters of the CSG cell, the CSG cell identifier may be used to obtain the CSG cell global identifier corresponding to the CSG cell identifier, and then The physical parameters of the target cell can be obtained through the CSG whi te list. If the mobile terminal measures the physical parameters of the target cell when measuring the CSG cell, After saving, the physical parameters of the corresponding CSG cell can also be obtained directly through the CSG cell identifier.

A person skilled in the art can understand that all or part of the steps of implementing the above embodiments can be completed by a program to instruct related hardware, and the program can be stored in a computer readable storage medium. , including the method steps described above.
