Description
Technical Field
The present invention relates to the field of communications, and in particular, to a measurement configuration method, a terminal, and a network device.
Background
Carrier Aggregation (CA) is a technology introduced by long term evolution (LTE-Advanced) technology to increase the transmission bandwidth of a user network, and is used to meet the requirement of increasing the peak rate and system capacity of a single user. When the secondary cell is configured by using the CA technology, the primary cell determines whether to add the secondary cell according to a measurement report reported by User Equipment (UE), where the measurement report includes a Physical Cell Identity (PCI) and a Reference Signal Receiving Power (RSRP) or a Reference Signal Receiving Quality (RSRQ) of the measurement cell.
Because the ideal backhaul is established between the primary cell and the secondary cell for carrier aggregation, after the connection between the primary cell and the secondary cell is established, the UE needs to consider the effective area of the primary cell when establishing the secondary cell, and the effective area indicates the range of the cell for carrier aggregation that can be established with the primary cell. Currently, when a terminal performs carrier aggregation in an idle state, a cell within an effective area is measured according to measurement configuration information, and when a UE moves outside the effective area, the measurement of the cell is stopped. Since the UE stops the cell measurement when moving outside the effective area, according to the existing idle measurement configuration information method, when the UE moves outside the effective area, the UE cannot acquire the measurement report of the neighboring cell when establishing the primary cell connection, so that the secondary cell connection for carrier aggregation cannot be established quickly.

An embodiment of the present invention provides a system architecture for carrier aggregation, as shown in fig. 1, including a terminal 01, a base station 02, a base station 03, and a base station 04.
Wherein, the ideal backhaul is between the base station 02 and the base station 03, and neither the base station 04 nor the base station 02 nor the base station 03 is the ideal backhaul.
The terminal 01 is configured to perform data interaction with the base station and establish Radio Resource Control (RRC) connection. Terminal 01 may be a User Equipment (UE), such as: a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a smart phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite radio, and/or other devices for communicating over a wireless system.
The base station 02, the base station 03 and the base station 04 are used for performing data interaction with the terminal 01 and establishing RRC connection with the terminal 01; base station 02, base station 03, and base station 04 may also be used for data interaction with the core network.
According to the above system architecture, an embodiment of the present invention provides a measurement configuration method, as shown in fig. 2, including:
101. and when the terminal leaves the effective area of the first network equipment, the first information is sent to the second network equipment.
The first information is used for requesting measurement configuration information, and the measurement configuration information comprises at least one cell to be measured for carrier aggregation; the active area of the first network device includes cells that are carrier aggregated with cells of the first network device.
Illustratively, as shown in the system architecture shown in fig. 1, the first network device may be the base station 02 or the base station 03, and since there is an ideal backhaul between the base station 02 and the base station 03, the effective area of the first network device includes cells of the base station 02 and the base station 03. When the terminal moves out of the coverage of the base stations 02 and 03 and moves to the coverage of the base station 04, since there is no ideal backhaul between the base station 04 and the base stations 02 and 03, the measurement configuration information of the terminal in the effective area of the first network device is invalid and cannot be used for carrier aggregation for the cell of the base station 04. Therefore, when the terminal leaves the effective area of the base station 02 or 03 and enters the coverage area of the base station 04, it needs to request new measurement configuration information that can be used for carrier aggregation with the cell of the base station 04 from the base station, that is, the terminal sends first information to the second network device for requesting new measurement configuration information, where the second network device in the embodiment of the present invention may be the base station 04 in fig. 1.
When the terminal is in the coverage of the second network device, the second network device has a new effective area, and the new effective area includes cells which can perform carrier aggregation with the cells of the second network device. For example, when the second network device is the base station 04 in fig. 1, the effective area of the second network device may include cells of the base station 05, the base station 06, or other base stations, and the base station 05 or the base station 06 is not shown in fig. 1, but it should be clear to those skilled in the art that there are cells of other base stations which can perform carrier aggregation with the cells of the base station 04 outside the base station 02 and the base station 03.
Optionally, when the terminal leaves the active area of the first network device and enters the active area of the second network device, the terminal may be in the INACTIVE state.
When the terminal is in the INACTIVE state, the terminal may move in a radio access network (RNA) region, and at this time, the core network always considers that the terminal is in the connected state, thereby retaining RRC configuration information of the terminal. Therefore, when the terminal is in INACTIVE state, if the terminal needs to reestablish RRC connection with the base station, it needs to send an RRC connection recovery request message to the base station to recover the RRC connection with the base station. Therefore, when the terminal leaves the effective area of the first network device, if the terminal is in the INACTIVE state, the first information may be carried in the RRC connection resume message.
Specifically, when the terminal is in the INACTIVE state, the terminal sends an RRC connection recovery request message to the second network device, where the RRC connection recovery request message includes a recovery reason resumecuse field, and the field is used to indicate a reason for RRC connection recovery. The existing reasons for RRC connection restoration include emergency, high priority Access highpriority Access, mobile terminal-Access mt-Access, mobile origin-signaling mo-signaling, mobile origin-Data transmission mo-Data, mobile origin-voice call mo-VoiceCall, mobile origin-video call mo-VideoCall, mobile origin-SMS, radio Access network-Update rna-Update, mobile phone service-priority Access mps-priority Access, and mass call service-priority Access mcs-priority Access, and in addition, the mass call response field further includes reserved flag bits spark 1-spark 5.
In the embodiment of the present invention, the first message may be that reserved flag spare1 in the ResumeCause field is set to idle measurement request idleMeasReq, which is used to request measurement configuration information. Because the existing ResumeCause includes 11 reasons, the idleMeasReq set by spare1 may be used as the 12 th recovery reason of the ResumeCause field in the embodiment of the present invention. In specific implementation, spare1 is set to idleMeasReq, and the value of ResumeCause is set to 12, that is, it indicates that the RRC connection recovery request message containing the information is only for acquiring measurement configuration information, and not for establishing RRC connection. Of course, those skilled in the art may also set the reserved flag spare2 to idleMeasReq and the ResumeCause value to 13; or the reserved flag spare5 is set to idleMeasReq and the value of ResumeCause is set to 16. The corresponding relationship between the reserved flag bit set in the RRC connection recovery request message and the value of resumecuse may be shown as the following table:
TABLE 1
| Reserved flag bit | Value of ResumeCoose |
| spare1 | 12 |
| spare2 | 13 |
| spare3 | 14 |
| spare4 | 15 |
| spare5 | 16 |
102. The second network device receives the first information from the terminal.
Specifically, when the terminal is in the INACTIVE state, the second network device receives an RRC connection recovery request message sent by the terminal, and obtains the first information by analyzing the RRC connection recovery request message.
103. The second network device sends the measurement configuration information to the terminal.
The measurement configuration information includes a cell identifier of a cell to be measured.
Specifically, after receiving the RRC connection recovery request message sent by the terminal, the second network device determines cell information capable of performing carrier aggregation with a cell in which the terminal is currently located according to the first information obtained through analysis, adds a cell identifier of the determined cell to the measurement configuration information, and sends the measurement configuration information to the terminal.
The measurement configuration information may be carried in an RRC connection release message, and the second network device sends the RRC connection release message to the terminal, so as to send the measurement configuration information to the terminal.
104. The terminal receives measurement configuration information from the second network device.
Specifically, the terminal receives an RRC connection release message sent by the second network device, and analyzes the RRC connection release message to obtain measurement configuration information.
105. And the terminal carries out carrier aggregation according to the measurement configuration information.
After the terminal acquires the measurement configuration information sent by the second network device, the terminal may measure the corresponding cell according to the cell identifier in the measurement configuration information, and directly perform carrier aggregation with the eligible cell in the measurement configuration information after the terminal establishes the connection with the primary cell.
Optionally, as shown in fig. 3, after step 102, the method further includes:
201. the second network device sends an RRC connection setup message to the terminal.
The RRC connection setup message instructs the terminal to establish an RRC connection with the second network device.
Optionally, when the terminal leaves the active area of the first network device and enters the active area of the second network device, the terminal may also be in an IDLE state.
When the terminal is in the IDLE state, the RRC configuration information of the terminal is not reserved in the core network because the connection between the terminal and the core network is already disconnected. Therefore, when the terminal establishes the RRC connection in the IDLE state, it is necessary to reinitiate the RRC connection establishment request procedure to reestablish the RRC connection between the terminal and the base station. Therefore, when the terminal leaves the effective area of the first network device, if the terminal is in the IDLE state, the first information is carried in the RRC connection establishment request message.
Specifically, when the terminal is in the IDLE state, step 101 may be that the terminal sends an RRC connection establishment request message to the second network device, where the first information is carried in the RRC connection establishment request message. The RRC connection establishment request message includes an establishment cause, which is used to indicate a reason for the RRC connection establishment, and the reason for the RRC connection establishment included in the establishment cause is the same as the reason for the RRC connection recovery included in the ResumeCause field, which is not described herein again. When the terminal sends an RRC connection establishment request message to the second network device, the embodiment of the present invention may also achieve the purpose of requesting measurement configuration information by using the above method for setting the reserved flag. Different from the foregoing, the reservation flag included in the establishmentause field in the RRC connection setup request message is spare6-spare1, and therefore, the corresponding relationship between the reservation flag and the value of the establishmentause is as shown in table 2 below:
TABLE 2
| Reserved flag bit | Value of EstableshmentCause |
| spare6 | 12 |
| spare5 | 13 |
| spare4 | 14 |
| spare3 | 15 |
| spare2 | 16 |
| spare1 | 17 |
Table 2 shows a correspondence between a reserved flag bit set in the RRC connection establishment request message and a value of establishmencause, and if spark 6 is set to idleMeasReq, the value of establishmencause is set to 12; if spark 5 is set to idleMeasReq, then the value of establishmencause is set to 13.
Therefore, when the terminal leaves the effective area of the first network device, enters the effective area of the second network device and is in an IDLE state, the terminal sends an RRC connection establishment request message to the second network device; and after receiving the RRC connection establishment request message, the second network equipment sends an RRC connection establishment message to the terminal, and indicates the terminal to establish RRC connection with the second network equipment.
202. The terminal receives an RRC connection setup message from the second network device.
203. And the terminal establishes the RRC connection between the terminal and the second network equipment according to the RRC connection establishment message and sends an RRC connection establishment completion message to the second network equipment.
The RRC connection setup complete message indicates that the RRC connection setup between the terminal and the second network device is complete.
And the terminal establishes RRC connection with the second network equipment according to the received RRC connection establishment message, and sends an RRC connection establishment result to the second network equipment, namely sends an RRC connection establishment completion message to the second network equipment.
204. The second network device receives an RRC connection setup complete message from the terminal.
And the second network equipment receives the RRC connection establishment completion message sent by the terminal, and the RRC connection establishment between the terminal and the second network equipment is completed.
After the second network device establishes the RRC connection, the second network device performs step 103, that is, before the terminal performs data interaction with the second network device, the second network device directly sends an RRC connection release message to the terminal, where the RRC connection release message includes the measurement configuration information in step 103.
Optionally, as shown in fig. 4, step 105 includes:
1051. and the terminal measures the cell to be measured in the measurement configuration information and sends the measurement report to the second network equipment.
Wherein the measurement report comprises measurement results of the cell to be measured.
Specifically, after receiving the measurement configuration information sent by the second network device, the terminal measures the corresponding cell according to the cell identifier of the cell included in the measurement configuration information, stores the measurement result obtained by the measurement in the measurement report, and sends the measurement report to the second network device.
1052. The second network device receives a measurement report from the terminal.
1053. And the second network equipment determines the target cell from the measurement result of the cell to be measured and sends an RRC connection reconfiguration message to the terminal.
The target cell is a cell with a measurement result larger than a preset threshold value in the cell to be measured, and the RRC connection reconfiguration message comprises a cell identifier of the target cell.
Specifically, after the terminal establishes a main cell connection with the second network device, the second network device receives a measurement report sent by the terminal, and may select a cell with an optimal measurement result from the measurement report as a target cell. Of course, since there may be 2 cells or more than 2 cells for carrier aggregation, a person skilled in the art may preset a threshold as a standard for selecting a target cell, and use a cell to be measured in a measurement result that is higher than the preset threshold as the target cell.
For example, the measurement report may include the measurement results of cell 1, cell 2, cell 3, cell 4, and cell 5. Taking RSRP as an example, the preset threshold may be set to-85 dBm. The RSRP of the cell 1 is-70 dBm, the RSRP of the cell 2 is-100 dBm, the RSRP of the cell 3 is-110 dBm, the RSRP of the cell 4 is-75 dBm, and the RSRP of the cell 5 is-85 dBm, so that the second network device may determine that the cell 1, the cell 4, and the cell 5 are target cells. Of course, the above examples are only exemplary, and those skilled in the art may set the preset threshold to determine the cells that can be used for terminal carrier aggregation.
Taking RSRQ as an example, the preset threshold may be set to 15, where RSRQ of the cell 1 is 2, RSRP of the cell 2 is 11, RSRP of the cell 3 is 10, RSRP of the cell 4 is 16, and RSRP of the cell 5 is 8, then the second network device may determine that the cell 4 is the target cell. Of course, the above examples are only exemplary, and those skilled in the art may set the preset threshold to determine the cells that can be used for terminal carrier aggregation.
After the second network device determines the target cell, the cell identifier of the target cell may be added to the RRC connection reconfiguration message, and the second network device sends the RRC connection reconfiguration message carrying the cell identifier of the target cell to the terminal.
1054. And the terminal receives the RRC connection reconfiguration message sent by the second network equipment and establishes the connection between the terminal and the target cell according to the RRC connection reconfiguration message.
And after receiving the RRC connection reconfiguration message sent by the second network equipment, the terminal analyzes the RRC connection reconfiguration message to obtain the cell identifier of the target cell and establishes RRC connection with the target cell corresponding to the cell identifier.
1055. And the terminal sends an RRC connection reconfiguration finishing message to the second network equipment.
The RRC connection reconfiguration complete message indicates that the connection establishment of the terminal and the target cell is completed.
1056. The second network device receives an RRC connection reconfiguration complete message from the terminal.
And the second network equipment receives the RRC connection reconfiguration completion message sent by the terminal, and the establishment of the RRC reconfiguration connection between the terminal and the second network equipment is completed. At this time, after the terminal establishes the connection with the primary cell, the terminal establishes the connection with the target cell, that is, the carrier aggregation of the terminal is completed.
The embodiment of the invention provides a method for measurement configuration, which comprises the following steps: when the terminal leaves the effective area of the first network equipment, first information is sent to the second network equipment; the first information is used for requesting measurement configuration information, and the measurement configuration information comprises at least one cell to be measured for carrier aggregation; the second network equipment receives the first information from the terminal and sends measurement configuration information to the terminal; and the terminal receives the measurement configuration information from the second network equipment and carries out carrier aggregation according to the measurement configuration information.
