Description

  The present invention relates to the field of wireless communication technology, and in particular, to a CA processing method and apparatus.

  Network sharing refers to cooperation or sharing in a telecommunications network infrastructure or network equipment between multiple operators (or third parties). Sharing of telecommunications network infrastructure includes sharing of site infrastructure such as site location, equipment room facilities, steel towers, power supplies. Network device sharing includes facility sharing for telecommunications network devices such as base stations, transmission networks, and core networks.

  Operators are distinguished using a public land mobile network identifier (PLMN_ID). In one network sharing scenario, multiple operators can share the same frequency or the same cell. In this case, each shared cell sets all supported PLMN_IDs, and the next generation base station (E-UTRAN NodeB, eNodeB) uses the air interface system message to send all supported PLMN_IDs. Broadcast PLMN_ID. The UE selects one PLMN_ID from a plurality of PLMN_IDs as a serving PLMN_ID, and reports the selected PLMN_ID to the eNodeB. Next, the eNodeB selects the core network of the operator corresponding to the PLMN_ID according to the PLMN_ID.

  In the case of a long term evolution (LTE) system, the maximum bandwidth is 20 MHz. For the Long Term Evolution-Advanced (LTE-Advanced, LTE-A) system, a 1 Gbyte downlink peak rate and a 500 Mbps uplink peak rate are required. In order to meet the essential requirements, carrier aggregation (Carrier Aggregation, CA) technology is introduced in the LTE-A system, and multiple consecutive or discontinuous carriers are aggregated to provide the required rate. Accordingly, the user equipment is serviced. Using CA technology, resource utilization can be maximized and discrete spectrum resources can be used effectively.

  Currently, CA is applied to non-network sharing scenarios. However, in the network sharing scenario, since a plurality of operators can share the same cell with the same frequency, the CA processing method based on the non-network sharing scenario cannot be applied.

  The present invention provides a CA processing method and device in order to provide a CA processing method applicable to a network sharing scenario.

In the embodiment of the present invention, the second cell is determined by the PLMN_ID used by the CA user equipment of the first cell and the frequency supported by the CA user equipment,
The first cell is the cell that the CA UE is currently accessing, and the CA is a second PLMN_ID supported by a second cell in the first cell and a first PLMN_ID used by the CA user equipment And the frequency used by the second cell can be supported by the CA user equipment;
Depending on the determined second cell, CA measurement control information is transmitted to the CA user equipment, or the CA cell is transmitted to the CA user equipment, or the CA cell is set for the CA user equipment. In the embodiment of the present invention, since the target cell is determined by the PLMN_ID used by the CA user equipment in the accessed cell, the CA process can be executed in a network sharing scenario.

  The CA user apparatus according to the embodiment of the present invention is a user apparatus that can simultaneously support data transmission and reception at a plurality of frequencies.

  As shown in FIG. 1, a cell-based CA processing method according to an embodiment of the present invention includes the following steps:

  Step 101: A second cell is determined by the PLMN_ID used by the CA user equipment of the first cell and the frequency supported by the CA user equipment. The first cell is the cell that the CA UE is currently accessing, and the CA is a second PLMN_ID supported by a second cell in the first cell and a first PLMN_ID used by the CA user equipment The frequency used by the second cell can be supported by the CA user equipment.

  Step 102: Send CA measurement control information including the frequency used by the second cell to the CA user equipment, or set the second cell as a CA cell for the CA user equipment.

The first PLMN_ID used by the CA user equipment in the first cell and the second PLMN_ID where CA is performed include, but are not limited to, at least one of the following:
The second PLMN_ID is the same as the first PLMN_ID, and the second PLMN_ID is equivalent to the first PLMN_ID. Here, equivalent PLMNs have the same position, for example, have the same priority.

  In addition to the above two types, the PLMN_ID supported by the second cell and performing CA by the PLMN_ID used by the CA user equipment in the first cell may be set according to the essential requirements of the operator.

  In step 101, when the second cell is determined by the PLMN_ID used by the CA user equipment in the first cell and the frequency supported by the CA user equipment, the following is realistic:

  Case 1: PLMN_ID is screened before the frequency is screened.

  Specifically, a cell that matches a frequency that can be supported by the CA user equipment is selected as a second cell from the cells that support the first PLMN_ID and the second PLMN_ID that can be executed by the CA.

  Case 2: The frequency is screened before the PLMN_ID is screened.

  Specifically, a cell that supports the first PLMN_ID and the second PLMN_ID that can be executed by the CA is selected as the second cell from the cells that match the frequency that can be supported by the CA user apparatus.

  In case 1 above, there are many ways to determine the second cell, some of which are described below.

  Cell determination method 1: A cell that supports the second PLMN_ID is selected from the first cell set, and a frequency that can be supported by the CA user equipment is selected from the selected cell that supports the second PLMN_ID. Select the cell to match.

  Specifically, the cell supporting the PLMN_ID supported by the second cell is selected from the second cell set including the first cell. The first cell set includes at least two cells capable of performing CA. A cell that adapts a frequency that can be supported by the CA user equipment is selected as the second cell from the selected cells.

  In the cell determination method 1, the first cell set is configured based on cell granularity, and the configuration determines which cells are included in the first cell set.

  In implementation, a cell that adapts a frequency that can be supported by the CA user equipment is selected from the first cell set, and a cell that supports the first PLMN_ID and a second PLMN_ID capable of performing CA is supported by the CA user equipment. The second cell is selected from the selected cells in which possible frequencies are adapted.

  First, cell filtering using PLMN_ID is processed. That is, the cell that supports the PLMN_ID supported by the second cell is selected from the first cell set including the first cell. Next, cell filtering using one frequency is processed. That is, the cell that adapts the frequency that can be supported by the CA user apparatus is selected as the second cell from the selected plurality of cells.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

  As shown in FIG. 2, the CA processing method using the first cell set according to an embodiment of the present invention includes the following:

  Step 201: Determine a CA user device.

  Step 202: Determine a first cell set including a first cell accessed by a CA user equipment.

  Step 203: If the cell is a non-access cell for the CA user equipment, select a cell supporting PLMN_ID capable of performing CA with the PLMN_ID used by the first cell from the determined first cell set.

  Step 204: Determine the frequency used by the selected cell.

  Step 205: Select one frequency that can be supported by the CA user equipment from the determined frequencies used by the selected cell, and use the cell corresponding to the selected frequency as the second cell.

  Below, the target cell determination method 1 is demonstrated using an example.

  Assume that cell 1 supports PLMN-A and PLMN-B, cell 2 supports PLMN-A, and cell 3 supports PLMN-B and PLMN-C. Cell 1, cell 2, and cell 3 constitute a first cell set 1. PLMN-A, PLMN-B, and PLMN-C represent different PLMN_IDs.

  For CA user equipment 1 belonging to PLMN-A and accessing cell 1, any other cell that supports PLMN-Awo or supports PLMN equivalent to PLMN-A, ie cell 2 is the first cell first. Select from set (ie, first cell set 1). When the CA user apparatus 1 supports the frequency corresponding to the cell 2, CA measurement control information of the frequency corresponding to the cell 2 is distributed (or the cell 2 is configured). Since the PLMN supported by the cell 3 does not include a PLMN capable of performing CA by the PLMN-A, the frequency corresponding to the cell 3 regardless of whether the CA user equipment 1 supports the frequency corresponding to the cell 3 or not. The CA measurement control information is not distributed (that is, the cell 3 is not configured as the CA cell for the CA user equipment 1).

  For CA user equipment 2 belonging to PLMN-B and accessing cell 3, any other cell supporting PLMN-B or supporting PLMN equivalent to PLMN-B, i.e. cell 1 first Select from a cell set (ie, first cell set 1). When CA user equipment 2 supports a frequency corresponding to cell 1, CA measurement control information of a frequency corresponding to cell 1 is distributed (or cell 1 is configured as a CA cell of CA user equipment 2). Since cell 2 does not support PLMN_ID that can execute CA by PLMN-B, regardless of whether or not the CA user equipment supports the frequency corresponding to cell 2, CA measurement control information of the frequency corresponding to cell 2 is Not distributed (that is, cell 2 is not configured as a CA cell for CA user equipment 2).

  For the CA user equipment 3 that belongs to the PLMN-C and accesses the cell 3, the first cell set (that is, the first cell set 1) is a PLMN other than the cell 3, but the CA is executed by the PLMN-C. Does not include any other cells to support. Therefore, the CA measurement control information is not distributed (or a CA cell is not configured for the CA user apparatus 3).

  Cell determination method 2: A cell that adapts a frequency that can be supported by the CA user equipment is selected as the second cell from the second cell set that supports the second PLMN_ID.

  Specifically, a cell that adapts a frequency that can be supported by a CA user equipment includes a first cell and a second cell set including a PLMN_ID used by the CA user equipment in the first cell, Cell is selected. At this time, each second cell set includes at least two cells and a PLMN_ID supported by the included cells. CA can be performed with a PLMN_ID supported by each cell in the same second cell set.

  In the cell determination method 2, the second cell set is configured based on the cell granularity and the PLMN_ID granularity, and one second cell set is determined by the configuration, which cell includes and corresponds to the cell Which PLMN_ID to include is included.

  In implementation, cell filtering using PLMN_ID is processed first. That is, the second cell set including the PLMN_ID used by the CA user equipment in the first cell is selected. Next, cell filtering using one frequency is processed. That is, the cell that adapts the frequency that can be supported by the CA user apparatus is selected as the second cell from the cell set.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

  In implementation, the second cell set including the first PLMN can be determined by the configuration information of the second cell set.

  Preferably, the configuration information of the second cell set may be any information used to characterize an object included in the second cell set, for example, a cell ID of a cell included in the second cell set, It may be a PLMN_ID supported by a cell included in the second cell set.

  As shown in FIG. 3, the CA processing method using the second cell set according to an embodiment of the present invention includes the following:

  Step 301: Determine a CA user device.

  Step 302: Determine a second cell set including the PLMN_ID used by the CA user equipment in the accessed cell.

  Step 303: Determine a frequency to be used by a cell in the determined second cell set.

  Step 304: Select one frequency that can be supported by the CA user equipment from the determined frequencies used by the cell, and use the cell corresponding to the selected frequency as the second cell.

Below, the target cell determination method 2 is demonstrated using an example.
Example 1

  Assume that cell 1 supports PLMN-A and PLMN-B, cell 2 supports PLMN-A, and cell 3 supports PLMN-B and PLMN-C.

  According to each configuration, the second cell set 1 includes PLMN-A of cell 1 and PLMN-A of cell 2; second cell set 2 includes PLMN-B of cell 1 and PLMN-B of cell 3 . Needless to say, the second cell set 1 is a cell set that supports PLMN-A, and the second cell set 2 is a cell set that supports PLMN-B.

  For CA user equipment 1 that belongs to PLMN-A and accesses cell 1, selection is performed in a second cell set that supports PLMN-A (ie, second cell set 1). When CA user apparatus 1 supports a frequency corresponding to cell 2, CA measurement control information of a frequency corresponding to cell 2 is distributed (or cell 1 is configured as a CA cell of CA user apparatus 2).

For CA user equipment 2 that belongs to PLMN-B and accesses cell 3, selection is performed in a second cell set that supports PLMN-B (ie, second cell set 2). When CA user equipment 2 supports a frequency corresponding to cell 1, CA measurement control information of a frequency corresponding to cell 1 is distributed (or cell 1 is configured as a CA cell of CA user equipment 2).
Example 2

  Cell 1, cell 2 and cell 3 all support PLMN-A and PLMN-B, but PLMN-A wants to perform CA in cell 1 and cell 2, and PLMN-B Suppose we want to perform CA at 3.

  According to each configuration, the second cell set CA set 1 includes the PLMN-A of cell 1 and the PLMN-A of cell 2; the second cell set CA set 2 includes the PLMN-B of cell 2 and the PLMN of cell 3 Includes -B.

  For CA user equipment that belongs to PLMN-A and accesses cell 1, selection is performed in a second cell set that supports PLMN-A (ie, second cell set 1). When CA user apparatus 1 supports a frequency corresponding to cell 2, CA measurement control information of a frequency corresponding to cell 2 is distributed (or cell 1 is configured as a CA cell of CA user apparatus 2). Since the second cell set 1 does not include the cell 3, regardless of whether or not the CA user equipment supports the frequency corresponding to the cell 3, the CA measurement control information of the frequency corresponding to the cell 3 is not distributed (or Cell 3 is not configured as the CA cell of CA user equipment 1).

  For CA user equipment 2 that belongs to PLMN-B and accesses cell 2, selection is performed in a second cell set that supports PLMN-B (ie, second cell set 2). When CA user equipment 2 supports a frequency corresponding to cell 3, CA measurement control information of a frequency corresponding to cell 3 is distributed (or cell 3 is configured as a CA cell of CA user equipment 2). Since the second cell set 1 does not include the cell 1, the CA measurement control information of the frequency corresponding to the cell 1 is not distributed regardless of whether or not the CA user apparatus supports the frequency corresponding to the cell 1 (or Cell 1 is not configured as a CA cell for CA user equipment 2).

  In case 2 above, there are many ways to determine the second cell, some of which are described below.

  Cell determination method 3: A cell in which a frequency that can be supported by the CA user apparatus is adapted is selected from a first cell set including the first cell. In this case, the first cell set includes at least two cells capable of performing CA. Then, a cell supporting the PLMN_ID supported by the second cell is selected as the second cell from the selected cells.

  In the cell determination method 3, the first cell set is configured based on cell granularity, and the configuration determines which cells are included in the first cell set.

  In implementation, cell filtering using one frequency is processed first. That is, a cell that adapts a frequency that can be supported by the CA user equipment is selected from the first cell set including the first cell. Next, cell filtering using PLMN_ID is processed. That is, the cell that supports the PLMN_ID supported by the second cell is selected as the second cell from the selected cells.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

  Cell determination method 4: Select a cell supporting a PLMN_ID supported by the second cell and a frequency supported by the user equipment from the third cell set including the first cell. In this case, each second cell set includes at least two cells and frequencies supported by all included cells. CA can be performed between PLMN_IDs supported by each cell in the same second cell set.

  In implementation, cell filtering using frequencies is processed. That is, the third cell set including the first cell and the frequency supported by the user equipment is selected. Next, cell filtering using PLMN_ID is processed. That is, the cell supporting the PLMN_ID supported by the second cell is selected from the third cell set including the first cell and the frequency supported by the user equipment.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

Preferably, in step 102, for the transmission of CA measurement control information to the CA user equipment by the determined second cell,
Transmission of CA measurement control information of a frequency corresponding to the second cell to the CA user equipment is included.

Preferably, in step 102, the second cell is configured as a CA cell of the CA user equipment:
Includes a direct configuration of the second cell for the CA user equipment.

Preferably, the method is after step 102:
The method further includes configuring the second cell as a CA cell of the CA user equipment according to the measurement information received from the CA user equipment. In this case, the measurement information is acquired by the measurement performed by the CA user apparatus by the CA measurement control information.

  Since a 3GPP protocol can be referred to for a specific method of configuring a CA cell based on measurement information, details are not described here.

  In an embodiment of the present invention, the second frequency is determined by the first PLMN_ID used by the CA user equipment in the accessed first cell and the frequency supported by the CA user equipment. In this case, the first cell uses the first frequency, and the CA can run with the second PLMN_ID supported by the second frequency and the first PLMN_ID used by the CA user equipment in the first cell, The second frequency can be supported by the CA user equipment. CA measurement control information including the second frequency is transmitted to the CA user apparatus. In the embodiment of the present invention, since the target cell is determined by the PLMN_ID used by the CA user equipment in the accessed cell, the CA process can be executed in a network sharing scenario.

  As shown in FIG. 4, a frequency-based CA processing method according to an embodiment of the present invention includes the following steps:

Step 401: A second frequency is determined by a first PLMN_ID used by a CA user equipment in the accessed first cell and a frequency supported by the CA user equipment. In this case, the first cell uses the first frequency, and the CA can run with the second PLMN_ID supported by the second frequency and the first PLMN_ID used by the CA user equipment in the first cell, The second frequency can be supported by the CA user equipment.

  Step 402: Transmit CA measurement control information including the second frequency to the CA user apparatus.

  The second frequency is different from the frequency supported by the first cell.

The first PLMN_ID used by the CA user equipment in the first cell and the second PLMN_ID where CA is performed include, but are not limited to, at least one of the following:
The second PLMN_ID is the same as the first PLMN_ID, and the second PLMN_ID is equivalent to the first PLMN_ID. Here, equivalent PLMNs have the same position, for example, have the same priority.

  In addition to the above two types, the PLMN_ID supported by the second cell and performing CA by the PLMN_ID used by the CA user equipment in the first cell may be set according to the essential requirements of the operator.

  In step 401, the second cell is determined by the PLMN_ID used by the CA user equipment in the first cell used by the CA user equipment in the accessed first cell and the frequency supported by the CA user equipment. When done, the following is realistic:

  Case 1: PLMN_ID is screened before the frequency is screened.

  Specifically, the frequency that can be supported by the frequency that can be supported by the CA user equipment is selected as the second frequency from the frequency that supports the first PLMN_ID and the second PLMN_ID that can be executed by the CA.

  Case 2: The frequency is screened before the PLMN_ID is screened.

  Specifically, a frequency that supports the first PLMN_ID and the second PLMN_ID that can be executed by the CA is selected as the second frequency from the frequencies that can be supported by the CA user apparatus.

  In case 1 above, there are many ways to determine the first frequency, some of which are described below.

  Frequency determination method 1: Select a frequency that supports the second PLMN_ID from the first frequency set, and select a frequency that can be supported by the CA user equipment from the selected frequency that supports the second PLMN_ID. , Select as the second frequency.

  The frequency supporting the PLMN_ID supported by the second cell is selected from the first frequency set. In this case, the first frequency set includes at least two frequencies. A frequency different from the frequency supported by the first cell that can be supported by the CA user equipment is selected as the second frequency from the selected frequency.

  In the frequency determination method 1, the first frequency set is configured based on frequency granularity, and the configuration determines which frequencies are included in the first frequency set.

  In implementation, cell filtering using PLMN_ID is first processed. That is, the frequency supporting the PLMN_ID supported by the second cell is selected from the first frequency set. Next, the step of filtering cells using frequency is processed. That is, a frequency that can be supported by the CA user equipment and is different from the frequency supported by the first cell is selected as the second frequency from the selected frequency.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

  As shown in FIG. 5, the CA processing method using the first frequency set according to an embodiment of the present invention includes:

  Step 501: A CA user device is determined.

  Step 502: Determine a first frequency set.

  Step 503: From the determined first frequency set, select a frequency that supports the PLMN_ID supported by the second cell.

  Step 504: Select a frequency different from the frequency supported by the first cell that can be supported by the CA user equipment as the second frequency from the selected frequency.

  Frequency determination method 2: A frequency that can be supported by the CA user equipment is selected as a second frequency from the second frequency set that supports the second PLMN_ID.

  Specifically, a frequency different from the frequency supported by the first cell, which can be supported by the CA user equipment, from the second frequency set including the PLMN_ID used by the CA user equipment in the first cell, Selected as the second frequency. CA can be performed between PLMN_IDs supported by each frequency in the same second frequency set.

  In the frequency determination method 2, the second frequency set is configured based on the frequency granularity and the PLMN granularity, and the configuration includes which frequency and which PLMN corresponding to the cell at that frequency is included in the second frequency set. It will be decided.

  In implementation, cell filtering using PLMN_ID is processed first. That is, the second frequency set including the PLMN_ID used by the CA user equipment in the first cell is selected. Next, the step of filtering cells using frequency is processed. That is, a frequency different from the frequency supported by the first cell, which can be supported by the CA user equipment, is selected as the second frequency from the second frequency set.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID which is also the PLMN_ID that can perform CA with the PLMN_ID used by the cell accessed by the CA user equipment. So, if each operator's CA user equipment performs CA on multiple carriers and the PLMN_ID supported by the multiple carriers belongs to that operator, the carrier of another operator (ie, other PLMN_IDs) Avoid using resources.

  As shown in FIG. 6, the CA processing method using the second frequency set according to an embodiment of the present invention includes:

  Step 601: A CA user device is determined.

  Step 602: Determine a second frequency set including the PLMN_ID used by the CA user equipment in the first cell.

  Step 603: Select a frequency from the second frequency set that is different from the frequency supported by the first cell, which may be supported by the CA user equipment, as the second frequency.

  In case 2 above, there are many ways to determine the second frequency, one of which is described below.

  Frequency determination method 3: Select a frequency that can be supported by the CA user equipment from the first frequency set, and a second PLMN_ID that can perform the first PLMN_ID and CA from the selected frequency that can be supported by the CA user equipment Is selected as the second frequency.

  Specifically, a frequency different from the frequency supported by the first cell, which can be supported by the CA user equipment, is selected from the first frequency set including the frequency supported by the first cell. In this case, the first frequency set includes at least two frequencies. The frequency supporting the PLMN_ID supported by the second cell is selected as the second frequency from the selected frequency.

  In the frequency determination method 3, the first frequency set is configured based on frequency granularity, and the configuration determines which frequencies are included in the first frequency set.

  In implementation, the step of filtering cells using frequency is first processed. That is, a frequency different from the frequency supported by the second cell, which can be supported by the CA user equipment, is selected from the first frequency set including the frequency supported by the first cell. Next, the step of filtering cells using PLMN_ID is processed. That is, the cell supporting the PLMN_ID supported by the second cell is selected as the second frequency from the selected frequency.

  The target cell selected by the CA user equipment adapts the frequency supported by the CA user equipment and supports the PLMN_ID used by the cell accessed by the CA user equipment and the PLMN_ID which is also the PLMN_ID capable of performing CA. Thus, it is ensured that each operator's CA user equipment performs CA on multiple carriers, avoiding the use of carrier resources of other operators (ie, other PLMN_IDs). In this case, the PLMN_ID supported by multiple carriers belongs to that operator.

Preferably, in step 202, the step of transmitting CA measurement control information to the CA user equipment at the determined second frequency comprises:
Transmitting CA measurement control information specific to the first frequency to the CA user equipment.

  Preferably, the method further comprises after step 202: configuring the second cell as a CA cell of the CA user equipment with the measurement information received from the CA user equipment.
