Description
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a measurement control method and device.
Background
In a Carrier Aggregation (CA) system and a dual connectivity system, a network device may configure a secondary cell for a User Equipment (UE) according to a measurement result reported by the UE, so that the secondary cell is combined with a primary cell to provide a service for the UE.
After the UE switches from the connected state to the idle state, the network device typically issues measurement configuration information (including an active area and a measurement cell) to the UE. Then, the UE measures the measurement cell in the effective area according to the measurement configuration information, and reports the measurement result to the network equipment when the UE is switched to the connection state.
Currently, in the process of measuring a measurement cell by a UE, if the UE moves out of an effective area, the UE will not measure the measurement cell any more, and delete the measured measurement result and measurement configuration information. Thus, once the UE leaves for a short time, it returns to the active area again. At this time, since the measurement configuration information is deleted, the UE cannot restart the measurement. In this case, when the UE switches to the connected state, the UE cannot report the measurement result to the network device quickly to assist the network device to add the secondary cell quickly.
Disclosure of Invention
The application provides a measurement control method and a measurement control device, which solve the problem that a secondary cell cannot be added quickly due to the fact that a user leaves an effective area for a short time.
In a first aspect, the present application provides a measurement control method, including: once the measurement control device determines to move out of the effective area, the measurement control device starts to search for a target cell corresponding to the effective area. When the target cell is searched, the measurement control device starts a first timer, and keeps the measurement configuration information sent by the network equipment and the measurement result obtained by the user equipment in the effective area. And when the situation that the effective area is not re-entered and the first timer is not overtime is determined, the measurement control device calculates a first difference value of a first RSRP of the target cell and a second RSRP of the service cell accessed by the user equipment at the first moment. Thereafter, the measurement control means calculates a second difference between the third RSRP and the fourth RSRP at a second time instant after the first time instant. And when the second difference is larger than the first difference, the measurement control device restarts the first timer and reserves the measurement configuration information and the measurement result. And finally, if the mobile terminal is determined to move into the effective area and the first timer is not overtime, the measurement control device continues to measure the measurement cell.
In the above scheme, when leaving the effective area, the measurement control device first determines whether measurement configuration information and measurement results need to be retained according to whether a target cell corresponding to the effective area can be measured. And if the target cell can be detected, judging whether the target cell is possible to return to the effective area or not according to the difference value of the RSRP of the target cell and the accessed serving cell. If the possibility of returning to the effective area is high, the first timer is continuously restarted to keep the measurement configuration information and the measurement result from being deleted. Therefore, once the network equipment enters the effective area again, the measurement control device can directly continue to measure the measurement cell according to the measurement configuration information sent by the previous network equipment, and report the measurement result to the network equipment when the network equipment enters the connection state, so as to assist the network equipment to quickly add the auxiliary cell. The problems that the measurement configuration information and the measurement result in the measurement control device are deleted, no measurement result is reported, and the measurement cannot be restarted immediately due to the fact that the user leaves the effective area again for a short time are solved.
In a second aspect, the present application provides a measurement control apparatus, for a user equipment or a chip on the user equipment, including: once the searching module determines that the user equipment moves out of the effective area, the searching module starts to search a target cell corresponding to the effective area. When the target cell is searched, the starting module starts a first timer, and keeps the measurement configuration information sent by the network equipment and the measurement result obtained by the user equipment in the effective area. When the determination module determines that the user equipment does not re-enter the effective area and the first timer is not overtime, the determination module determines a first difference value between a first RSRP of the target cell and a second RSRP of a serving cell accessed by the user equipment at a first time. Thereafter, the determining module determines a second difference between the third RSRP and the fourth RSRP at a second time subsequent to the first time. And when the second difference is larger than the first difference, the starting module restarts the first timer and reserves the measurement configuration information and the measurement result. And finally, if the mobile terminal is determined to move into the effective area and the first timer is not overtime, the processing module continues to measure the measurement cell.
In a third aspect, there is provided a measurement control apparatus for a user equipment or a chip on a user equipment, comprising a processor, wherein when the measurement control apparatus is operated, the processor executes computer-executable instructions to make the measurement control apparatus execute the measurement control method as described above.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.
In a CA system and a dual connectivity system (e.g., NR-NR system), a network device may configure a secondary cell for a UE according to a measurement result reported by the UE, so that the secondary cell is combined with a primary cell to provide a service for the UE.
In order to assist the network device to quickly establish the secondary cell, the UE may measure the measurement cell in an idle state, obtain a measurement result, and quickly report the measured measurement result to the network device when the UE switches to a connected state.
Further, in order to avoid unnecessary measurement performed by the UE, when the UE switches from the connected state to the idle state, the network device configures measurement configuration information (including an active area and a measurement cell) for the UE, so that the UE performs measurement on the measurement cell in the active area to generate a measurement result. For example, in a dual connectivity system, the network device may configure a cell capable of performing dual connectivity as an effective area to the UE, so that it may be avoided that the UE measures a cell incapable of performing dual connectivity with the network device. For another example, in the CA system, the network device may configure a cell capable of applying the carrier aggregation technology to the UE as an effective area, so that the UE may avoid measuring a cell incapable of applying the carrier aggregation technology.
Specifically, the following describes specific content of the measurement configuration information issued by the network device by taking the CA system as an example.
Firstly, since the carrier aggregation technology requires that the communication between any two adjacent cells in the CA system is an ideal backhaul connection, the resource information in the CA system can be scheduled in real time to ensure the real-time performance of the service of the UE.
Second, illustratively, as shown in fig. 1, the communication network architecture shown in fig. 1 includes a network device 101, a network device 102, a network device 103, and a UE 104. The cells of network device 101 include cell 1 and cell 2, the cells of network device 102 include cell 3 and cell 4, and the cells of network device 103 include cell 5 and cell 6. Further, the area 0 covers partial areas of the cell 1, the cell 2, the cell 3, the cell 4, and the cell 5. The UE104 resides in area 0.
Among them, there is an ideal backhaul between network device 101 and network device 102 (i.e. network device 101 and network device 102 can form a CA system, so that carrier aggregation technology can be applied between cell 1, cell 2, cell 3, and cell 4). The backhaul between network device 101 and network device 103 is non-ideal (i.e. network device 1 and network device 3 cannot form a CA system, so cell 1 and cell 2 cannot apply carrier aggregation techniques with cell 5 and cell 6).
In this way, since the cell of the network device 101 and the cell of the network device 102 can apply the carrier aggregation technology, the area covered by the network device 101 and the network device 102 can be used as an effective area, and other cells except the serving cell accessed by the UE104 in the area covered by the network device 101 and the network device 102 can be configured to the UE104 as measurement cells. I.e. the valid area in the measurement configuration information does not include the cell of the network device 103.
Similarly, if UE104 moves from the cell of network device 101 to the cell of network device 103, UE104 does not need to perform measurements on the cells of network device 101 and network device 102. In the cell of the network device 3, even if the UE104 measures the cells of the network device 101 and the network device 102, the network device 3 cannot perform carrier aggregation after the UE104 reports the measurement result.
Therefore, in the dual connectivity system and the CA system, it is necessary for the network device to configure the measurement configuration information for the UE.
To sum up, the specific process of the UE assisting the network device to quickly establish the secondary cell at present is generally: when the UE is switched from the connection state to the idle state, the network equipment issues measurement configuration information (including an effective area and a measurement cell) to the UE. Then, the UE measures the measurement cell in the effective area according to the measurement configuration information, and reports the measurement result to the network equipment. And the network equipment configures the auxiliary cell for the UE according to the measurement report result.
For an exemplary procedure of the communication method when the UE assists the network device to quickly establish the secondary cell, refer to fig. 2. The UE accesses a primary cell of a Master Node (MN), the MN adds a cell of a Secondary Node (SN) to the UE as a secondary cell according to a measurement result reported by the UE, and the primary cell and the secondary cell are combined to provide service for the UE.
The specific process comprises the following steps:
1. radio Resource Control (RRC) connection release carrying measurement configuration information.
Specifically, the MN configures measurement configuration information in the RRC message and issues the measurement configuration information to the UE (the UE enters an idle state). The measurement configuration information is as follows:
here, validyarea-r 15 CellList-r15 represents a list of arrangement of effective areas. measCellList-r15 CellList-r15 represents a configured list of measurement cells.
2. And the UE performs the advanced measurement (the UE is in an idle state) according to the measurement configuration information configured in the RRC message.
3. And the UE and the MN carry out random access. Thereafter, the UE sends an RRC connection restoration request to the accessed MN. Then, the MN replies an RRC connection recovery message to the UE, wherein the RRC connection recovery message carries the measurement result request. And finally, the UE performs RRC connection recovery according to the RRC connection recovery message and reports the measurement result (the UE enters a connected state).
4. And the MN sends an SN adding request to the SN according to the measurement result reported by the UE. And after determining that the SN addition response is received, the MN sends RRC connection reconfiguration to the UE to complete the addition process of the auxiliary cell of the UE.
When the step 2 is executed, that is, the UE is in an idle state, and in the process of measuring the measurement cell, the UE moves out of the effective area in the measurement configuration information, according to the current protocol, the user will not measure the measurement cell according to the measurement configuration information any more, and delete the measured measurement result. Thus, once the UE leaves for a short time, it returns to the active area again. At this time, since the measurement configuration information is deleted, the UE cannot restart the measurement. In this case, when the UE switches to the connected state, the UE cannot report the measurement result to the network device quickly to assist the network device to add the secondary cell quickly.
In view of the above problems, the present application provides a measurement control method and a measurement control apparatus for a UE in a carrier aggregation or dual connectivity system. The measurement control method specifically comprises the following steps: when the user equipment moves out of the effective area, the measurement control device does not delete the measurement configuration information and the measurement configuration result, but searches for a target cell of the effective area. And when the target cell is searched, calculating the difference value of the RSRP of the target cell and the current service cell accessed by the UE, and restarting the first timer when the difference value of the RSRP of the target cell and the service cell is increased. In this way, the measurement control apparatus keeps the measurement configuration information and the measurement result from being deleted by continuously restarting the first timer. Once the user equipment enters the effective area again, the measurement control device can directly continue to measure the measurement cell according to the measurement configuration information issued by the network equipment before, and report the measurement result to the network equipment. The method can assist the network equipment to quickly add the secondary cell.
In a specific implementation, the measurement control apparatus is used for a user equipment or a chip on the user equipment. Specifically, the measurement control apparatus has components as shown in fig. 3. Fig. 3 is a measurement control apparatus provided in an embodiment of the present application, and may include a processor 302, where the processor 302 is configured to execute application program codes, so as to implement the measurement control method in the present application.
The processor 302 may be a general-purpose Central Processing Unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more ics for controlling the execution of programs in accordance with the present disclosure.
As shown in fig. 3, the measurement control apparatus may further include a memory 303. The memory 303 is used for storing application program codes for executing the scheme of the application, and the processor 302 is used for controlling the execution.
The memory 303 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that may store static information and instructions, a Random Access Memory (RAM) or other type of dynamic storage device that may store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disk storage, optical disk storage (including compact disc, laser disc, optical disc, digital versatile disc, blu-ray disc, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. The memory may be self-contained and coupled to the processor via a bus. The memory may also be integral to the processor.
As shown in fig. 3, the measurement control device may further comprise a communication interface 301, wherein the communication interface 301, the processor 302, and the memory 303 may be coupled to each other, for example, via a bus 304. The communication interface 301 is used for information interaction with other devices, for example, to support information interaction between the measurement control apparatus and the network device, for example, to acquire data from the network device or send data to the network device.
It is noted that the apparatus structure shown in fig. 3 does not constitute a limitation of the measurement control device, which may comprise more or less components than those shown in fig. 3, or a combination of some components, or a different arrangement of components, in addition to those shown in fig. 3.
The following describes a measurement control method provided in an embodiment of the present application with reference to fig. 4 and 5 in conjunction with the measurement control apparatus shown in fig. 3.
Fig. 4 is a first flowchart illustrating a measurement control method according to an embodiment of the present application. Fig. 5 is a flowchart illustrating a second measurement control method according to an embodiment of the present application. Referring to fig. 4 and 5, the measurement control method includes the following steps.
401. And after the measurement control device determines to move out of the effective area, searching a target cell corresponding to the effective area.
Wherein, the effective area is configured for the user equipment by the network equipment.
Specifically, before determining to move out of the effective area, the measurement control apparatus needs to acquire measurement configuration information issued by the network device, where the measurement configuration information includes configuration of the effective area, configuration of the measurement cell, configuration of the first timer, and configuration of the second timer.
Further specifically, it is specified in the existing protocol that, in the sending of the measurement configuration information by the network device, the measurement time specified for the UE by the network device needs to be carried, and a second timer (for example, a timer T331) is used to configure the measurement time, where the configuration of the second timer is as follows:
wherein, measldleduty-r 15 estimated { sec10, sec30, sec60, sec120, sec180, sec240, sec300, spare } represents the configuration of the second timer.
On the basis of the above specification, the present application adds a first timer for determining whether the UE needs to keep the measurement configuration information and the measurement result. The timeout time of the first timer is preconfigured, for example, the timeout time of the first timer may be a default value, pre-stored, or obtained by being rewritten by a back-end manager. The specific protocol modified by the application is as follows:
here, measDeleteTimer estimated { sec1, sec2, sec5, sec10, sec30, sec60, sec120, spare }, which indicates the configuration of the first timer.
Then, the measurement control device measures the measurement cell in the effective area to generate a measurement result.
And finally, after the measurement control device determines to move out of the effective area, searching a target cell corresponding to the effective area. Specifically, the measurement control apparatus may search for the target cell by searching for a Reference Signal Receiving Quality (RSRQ) value of the measurement target cell to determine whether the target cell is searched for, or by searching for a Reference Signal Receiving Power (RSRP) value of the measurement target cell to determine whether the target cell is searched for. For example, when the RSRQ of the target cell is measured to have a value of 0, it is determined that the target cell cannot be searched. Or when the RSRP value of the target cell is measured to be 0, determining that the target cell cannot be searched.
402. And if the target cell is searched, starting a first timer, and reserving the measurement configuration information issued by the network equipment and the measurement result obtained by the user equipment in the effective area.
Optionally, if the measurement control apparatus does not search the target cell, the measurement configuration information and the measurement result are deleted.
403. And if the effective area is not moved into and the first timer is not overtime, determining a first difference value and a second difference value.
Wherein the first difference is: a difference between the first RSRP and the second RSRP. The first RSRP is the RSRP of the target cell measured at the first time. The second RSRP is an RSRP of a serving cell accessed at the first time. That is, the first difference is a difference between the first RSRP of the target cell and the second RSRP of the serving cell measured by the measurement control device at the first time.
The second difference is: a difference between the third RSRP and the fourth RSRP. And the third RSRP is the measured RSRP of the target cell at the second moment. And the fourth RSRP is the RSRP of the service cell accessed at the second moment. The duration between the first time and the second time is less than the duration of the first timer. The second time is after the first time. That is, the second difference is a difference between the third RSRP of the target cell and the fourth RSRP of the serving cell measured by the measurement control apparatus at a second time after the first time.
When the number of target cells corresponding to the effective area exceeds two, the measurement control device takes the measured maximum RSRP of the target cell as the RSRP of the target cell and participates in the calculation of the difference value.
In addition, the measurement control device determines that the time length between the first time and the second time should be less than the timeout time of the first timer according to the configuration of the first timer in the measurement configuration information issued by the network device.
404. And if the second difference is larger than the first difference, restarting the first timer, and reserving the measurement configuration information and the measurement result.
Optionally, if it is determined that the second difference is smaller than or equal to the first difference, the first timer does not time out, and the user does not return to the valid area, the process returns to step 403, and continues to determine the first difference and the second difference.
405. And if the mobile terminal is determined to move into the effective area and the first timer is not overtime, continuing to measure the measuring cell.
Specifically, the measurement control apparatus determines that the first timer has not timed out, and the user equipment returns to the valid area, and continues to perform measurement on the measurement cell. And when the user equipment enters the connection state again, the measurement control device controls the user equipment to report the measurement result to the network equipment. And then, the network equipment sends an auxiliary cell adding request to the network equipment of the auxiliary cell according to the measurement result reported by the user equipment, and sends RRC connection reconfiguration to the user equipment after receiving an auxiliary cell adding response replied by the network equipment of the auxiliary cell, thereby finally completing the adding process of the auxiliary cell of the user equipment.
Optionally, if it is determined that the first timer is overtime when the mobile terminal moves into the effective area, the measurement of the measurement cell is continued.
Optionally, step 405 further includes: and if the mobile terminal is determined not to move into the effective area and the first timer is overtime, deleting the measurement configuration information and the measurement result.
In the above scheme, when leaving the effective area, the measurement control device first determines whether measurement configuration information and measurement results need to be retained according to whether a target cell corresponding to the effective area can be measured. And if the target cell can be detected, judging whether the target cell is possible to return to the effective area or not according to the difference value of the RSRP of the target cell and the accessed serving cell. If the possibility of returning to the effective area is high, the first timer is continuously restarted to keep the measurement configuration information and the measurement result from being deleted. Therefore, once the network equipment enters the effective area again, the measurement control device can directly continue to measure the measurement cell according to the measurement configuration information sent by the previous network equipment, and report the measurement result to the network equipment when the network equipment enters the connection state, so as to assist the network equipment to quickly add the auxiliary cell. The problems that the measurement configuration information and the measurement result in the measurement control device are deleted, no measurement result is reported, and the measurement cannot be restarted immediately due to the fact that the user leaves the effective area again for a short time are solved.
In the embodiment of the present application, the measurement control apparatus may be divided into functional modules according to the method embodiments described above, for example, each functional module may be divided for each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, in the embodiment of the present application, the division of the module is schematic, and is only one logic function division, and there may be another division manner in actual implementation.
Referring to fig. 6, the present application provides a measurement control apparatus for a network device or a chip on the network device, including: the searching module 601 is configured to search for a target cell corresponding to the effective area after determining that the effective area is moved out.
