The technical solutions in the present application will be described below with reference to the accompanying drawings.
The technical solution of the embodiment of the application can be applied to various communication systems, for example: the embodiments of the present application are not limited by a long term evolution (long term evolution, LTE) system, an LTE frequency division duplex (frequency division duplex, FDD) system, an LTE time division duplex (time division duplex, TDD), a fifth generation (5th generation,5G) communication system, such as a 5G New Radio (NR) system, etc., and a future communication system (such as a sixth generation (6th generation,6G) communication system), or a system in which multiple communication systems are integrated, etc.

The communication system may include at least one network device, such as network device 101 shown in fig. 1. And the communication system may further comprise at least one terminal device, such as terminal device 104 shown in fig. 1. The network side in the communication system may include two cells working on different carriers, where coverage areas of the two cells may overlap, and the two cells may be two cells managed by the same access network device (such as a base station), where the deployment may be referred to as co-station deployment, as shown in fig. 1, where the access network device manages a cell 102 and a cell 103 with overlapping coverage areas at the same time, and carriers of the cell 102 and the cell 103 are different. Terminal device 104 is in the coverage of both cell 102 and cell 103 and is capable of receiving signals from cell 102 and signals from cell 103.
Fig. 2 is another schematic diagram of a communication system suitable for use in embodiments of the present application. As shown in fig. 2, coverage areas of cells managed by different access network devices may also overlap, and this deployment may be referred to as off-site deployment. As the cell 202 managed by the access network device 201 overlaps with the coverage of the cell 204 managed by the access network device 203, the carriers of the cell 202 and the cell 204 are different. Terminal device 205 is in the coverage of both cell 202 and cell 204 and is capable of receiving signals from cell 202 and signals from cell 204.
A cell is a unit that manages radio communication resources from the viewpoint of resource management, and a cell is understood to be a coverage area of a radio signal identified by a network device identifier or a global cell identifier. The physical layer resources of a cell include carriers, which are carriers used to carry radio signals from the physical layer perspective. The carrier occupies certain frequency domain resources and is characterized by carrier frequency points and the bandwidth of a carrier frequency band. In this application, carriers and cells may be interchanged.
The terminal device referred to in the embodiments of the present application may also be referred to as a terminal. The terminal may be a device having a wireless transceiving function. Terminals may be deployed on land, including indoors, outdoors, handheld, and/or vehicle-mounted; may also be deployed on the surface of water (e.g., a ship, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal device may be a User Equipment (UE). The UE includes a handheld device, an in-vehicle device, a wearable device, or a computing device with wireless communication capabilities. The UE may be a mobile phone (mobile phone), a tablet computer, or a computer with a wireless transceiver function, for example. The terminal device may also be a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, and/or a wireless terminal in smart home (smart home), etc.
The network device according to the embodiment of the present application includes a Base Station (BS), which may be a device deployed in a radio access network and capable of performing wireless communication with a terminal device. The base station may take many forms, such as a macro base station, a micro base station, a relay station, or an access point. The base station referred to in the embodiments of the present application may be a base station in a 5G system, a base station in an LTE system, or a base station in another system, which is not limited. Among them, the base station in the 5G system may also be called a transmission reception point (transmission reception point, TRP) or a next generation node B (generation Node B, gNB or gndeb). The base station may be an integrated base station, or may be a base station separated into a plurality of network elements, which is not limited. For example, the base station is a base station where a Centralized Unit (CU) and a Distributed Unit (DU) are separated, i.e., the base station includes CU and DU.
In a conventional scenario, each cell broadcasts a respective synchronization signal and system information (system information, SI), respectively. At present, an energy-saving scenario is proposed for a multi-carrier network, and one cell assists other carriers to broadcast system information. A base component carrier (basic component carrier, BCC) and a capacity carrier (capacity component carrier, CCC) may be included in the network, as shown in fig. 3, with the synchronization signals (synchronization signal, SS) and physical broadcast channel (physical broadcast channel, PBCH) blocks (SS and PBCH block, SSB) and SI of the BCC cell being broadcast by the cell of the BCC (denoted as BCC cell) and with the BBC cell also assisting the cell of the CCC (denoted as CCC cell) in broadcasting the SI of the CCC cell. The CCC cell only broadcasts discovery reference signals (discovery reference signal, DRS) for cell discovery and downlink synchronization or SSB of the CCC cell, and does not broadcast SI of the CCC cell. After the BCC cell receives the SI of the CCC cell, the terminal can detect the DRS or SSB of the CCC cell and realize downlink synchronization with the CCC cell, thereby establishing communication connection with the network through the CCC cell. And the CCC cell is used as a service cell of the terminal to provide network data transmission service for the terminal. The terminal receives system information of the CCC cell, which may be referred to as a system information cell, and update information of the system information from the BCC cell. Since SI is not broadcast, the air-time domain overhead is greatly reduced (when DRS is broadcast instead of SSB, since DRS symbols occupy less than SSB, the air-time domain overhead can be further reduced), the time domain shutdown opportunity of the CCC cell can be increased, and the power consumption of the CCC cell can be reduced. The power consumption saved by the CCC cell is larger than the power consumption increased by broadcasting the CCC cell system information by the BCC cell, so that the power consumption of the whole network can be reduced.
In a mobile communication system, mobility management of a terminal in a radio resource control (radio resource control, RRC) connected state generally refers to management of a serving cell change policy of the terminal in the RRC connected state, including cell handover (handover) or cell redirection. The network device may perform signal quality measurement of the serving cell and/or a neighboring cell of the serving cell by configuring the terminal, and determine whether a suitable target cell exists based on a measurement result reported by the terminal, thereby determining whether to start a cell handover or redirection procedure.
For the above-described power saving scenario, the following mobility scenarios may occur:
service cell change of terminal, system information cell unchanged
For example, in the scenario shown in fig. 4, the serving cell of the terminal is a CCC1 cell, and the system information cell is a BCC1 cell. The terminal moves from the CCC1 cell to the CCC2 cell within the coverage of the BCC1 cell, and the service cell of the terminal is changed to the CCC2 cell. And the terminal receives the system information of the CCC2 cell from the BCC1 cell, and the service cell of the terminal is changed, but the system information cell is unchanged.
Service cell of terminal unchanged, system information cell changed
For example, in the scenario shown in fig. 4, the serving cell of the terminal is a CCC2 cell, and the system information cell is a BCC1 cell. The terminal moves from the BCC1 cell to the BCC2 cell within the coverage of the CCC2 cell, and the terminal will receive the system information of the CCC2 cell in the BCC2 cell. The serving cell of the terminal is unchanged but the system information cell is changed.
Change of both serving cell and system information cell of terminal
For example, in the scenario shown in fig. 4, the serving cell of the terminal is a CCC1 cell, and the system information cell is a BCC1 cell. The terminal moves from the CCC1 cell to the coverage area where the CCC2 cell overlaps the BCC2 cell. The serving cell of the terminal is changed from the CCC1 cell to the CCC2 cell and the system information cell is changed from the BCC1 cell to the BCC2 cell.
The serving cell of the terminal is changed and no system information cell exists.
For example, in the scenario shown in fig. 4, the serving cell of the terminal is a CCC1 cell, and the system information cell is a BCC1 cell. When the terminal moves to the coverage area of the BCC1 cell outside the CCC1 cell, the service cell of the terminal is changed to the BCC1 cell, the BCC1 cell can provide own system information, and the terminal does not have the system information cell.
Aiming at the mobility situation in the energy-saving scene, a matched terminal mobility management scheme is also lacking to improve the communication reliability of the terminal under the condition of moving. In the energy-saving scenario, if the signal of the cell in which the terminal receives the system information is poor, the terminal cannot acquire the system information of the serving cell, and the failure to acquire the system information may affect the signal quality of the terminal in the serving cell. The terminal mobility management scheme needs to consider the signal quality of the serving cell and also the signal quality of the cell providing the system information for the terminal.

After determining that the first event occurs, the terminal measures that the signal quality of the first cell is smaller than a threshold value, or the signal quality of the second cell is smaller than the threshold value, and determines that the stopping condition of the first event is met, so that the first event is stopped.
In another example, the stopping condition of the first event is that the signal quality of the first cell is less than a threshold value for a duration of T2, or the signal quality of the second cell is less than a threshold value for a duration of T1.
After determining that the first event occurs, the terminal measures that the signal quality of the first cell is smaller than the threshold value and lasts for a duration of T2, or measures that the signal quality of the second cell is smaller than the threshold value and lasts for a duration of T1, and then the terminal determines that the stopping condition of the first event is met, so that the first event is determined to stop.

In the embodiments described in the examples of the present application, the condition for generating the first event and the condition for stopping the first event may be implemented individually or in combination with each other, and the present application is not limited thereto.
Illustratively, the first event of this embodiment 1 may be referred to as an extended A1 event.
The occurrence condition of the extended A1 event is that the following conditions are simultaneously satisfied:
occurrence condition 1: ms-Hys > Thresh, and for a period of T1;

And/or occurrence condition 2 may also include a case where Ma-Hys_a is equal to Thresh_a, i.e., occurrence condition 2 may be Ma-Hys_a. Gtoreq. Thresh_a for a period of T2.

In another example, the first cell and the second cell are cells employing different RATs. This first event may be referred to as a C7 event. The C7 event is that the signal quality of the first cell is less than a threshold and the signal quality of a cell transmitting system information of a different RAT than the first cell is greater than the threshold.
The occurrence condition of the C7 event is as follows: ma+hys_a < Thresh3 and mna+ofna+ocna-hys_a > Thresh4, and for a period of T2.
Where Ma is a measurement result of the first cell, mna is a measurement result of a third cell, which is a cell employing a different RAT from the first cell.
The stop condition of the C7 event is that: ma-Hys_a > Thresh3 or Mna+Ofna+Ocna+Hys_a < Thresh4, and for a period of T2.
Optionally, the case of equality may be further included in one or more of two inequalities of the occurrence condition and/or the stop condition in the C7 event, and specific reference may be made to the embodiment of the event occurrence condition 1 in the foregoing A5, which is not described herein for brevity.
The network device may send measurement configuration information to the terminal, where the measurement configuration information includes event-triggered configuration information, where the event-triggered configuration information is used to configure relevant parameters of the C7 event. The relevant parameters include one or more of the following:
hysteresis parameter Hys_a related to measurement result of third cell (i.e. adjacent cell adopting transmission system information of different RAT), offset Ofna exclusive to measurement object, offset Ocna exclusive to cell, threshold value Thresh4;
a measurement object specific offset Ofa related to the measurement result of the first cell, a cell specific offset Oca, an offset off_a, a threshold value Thresh3, and a duration T2.
The terminal can determine the relevant parameters of the C7 event according to the relevant parameters of the C7 event configured by the event trigger configuration information, thereby determining the occurrence condition and the stop condition of the C7 event. After obtaining the measurement result of the at least one cell, the terminal determines that the measurement result meets the occurrence condition of the C7 event, thereby determining that the C7 event occurs. After the terminal determines that the C7 event occurs, whether the event is stopped or not is determined based on measurement and judgment whether the stopping condition of the C7 event is met or not.
After determining that the first event occurs in S502, the terminal determines that the first event is used for triggering sending a measurement report associated with the cell measurement according to the measurement configuration information, and sends the measurement report to the network device. So that the network device uses the measurement report as a reference for mobility management of the terminal.
Optionally, the measurement configuration information for configuring the terminal to measure the at least one cell includes report configuration information, where the report configuration information is associated with measurement object information for indicating the at least one cell, and the report configuration information is used to configure a measurement report sent by the terminal.
Optionally, the report configuration information is specifically used to configure the standard triggering reporting the measurement report and the format of the measurement report.
Illustratively, the report configuration information includes report type information indicating criteria for triggering reporting of the measurement report. The measurement configuration information is further used to indicate that the measurement report associated with the cell measurement is triggered and sent by a first event, including: the report type information is used to indicate that the measurement report associated with the cell measurement was sent triggered by a first event.
It should be noted that the report configuration information may be used to indicate that the measurement report associated with the cell measurement is triggered by the first event or that the measurement report is periodically transmitted. In the embodiment shown in fig. 5, the report configuration information indicates that the measurement report was triggered by the first event. The terminal determines to send a measurement report to the network device in the case of occurrence of the first event, specifically based on the report type information in the measurement configuration information, but the present application is not limited thereto. If the report type information indicates that the measurement report is periodically transmitted, the terminal periodically transmits the measured measurement result of the at least one cell to the network device according to the report type information, but the present application is not limited thereto.
According to the above scheme, the network equipment configures the terminal to measure at least one cell including the first cell and/or the second cell, and can obtain the signal quality of the cell transmitting the system information of the serving cell. And the measurement configuration information configures that the measurement report related to the cell measurement is triggered and sent by the first event, so that the power overhead caused by reporting the cell measurement result when the terminal is not necessary can be reduced. After the first event occurs, the network device can acquire a measurement report related to the cell measurement, so that mobility management is performed on the terminal by referring to the measurement result of the cell transmitting the system information, the situation that the terminal cannot acquire the system information due to the fact that the signal quality of the cell transmitting the system information is reduced can be reduced, the reliability of terminal communication is improved, and the mobility management capability of the network to the terminal is improved.
The network device receives the measurement report from the terminal, and performs mobility management according to the measurement report.
In one embodiment, the network device sends first indication information to the terminal, where the first indication information is used to instruct the terminal to perform a cell change. The cell change includes a terminal changing a serving cell and/or a terminal changing a cell receiving system information of the serving cell.
For example, according to a measurement report from the terminal, the network device determines that there is a cell capable of providing service for the terminal and having a higher signal quality than the current serving cell, and/or determines that there is a cell capable of providing system information for the terminal and having a higher signal quality than the first cell, and the network device needs to change the cell of the terminal, and then the network device may send the first indication information to the terminal, and correspondingly, the terminal receives the first indication information from the network device, and performs cell change according to the first indication information. But the present application is not limited thereto.
By way of example and not limitation, the cell change includes one or more of a cell handover, a cell redirection, or a system information cell change.
The cell switching refers to that the serving cell of the terminal is changed from the source serving cell to the target serving cell without releasing the RRC connection, where the change of the cell receiving the system information may be involved to ensure the continuity of the service. Cell redirection refers to that the network equipment initiates RRC connection release to the terminal and instructs the UE to execute cell selection at the target frequency point to determine a new serving cell. The system information cell change means that the cell of the terminal receiving the system information changes from one cell to another cell in the case that the serving cell is unchanged.
In another embodiment, the network device sends second indication information to the terminal, the second indication information being used to instruct the terminal to stop cell measurements of the at least one cell.
Accordingly, the terminal receives the second indication information from the network device. In response to the second indication information, the terminal stops performing cell measurements of M cells, M being a positive integer.
The cell measurements of the M cells may be cell measurements of at least one cell configured by the measurement configuration information in S501, or the cell measurements of the M cells may be measurements of other cells performed by the terminal, and the M cells may include some or all of the at least one cell, or may not include cells in the at least one cell. This is not limited in this application, as may be the case.
For example, according to the measurement report of the terminal, the network device determines that the signal quality of the system information cell (i.e. the first cell) of the terminal is better, if the signal quality is higher than a preset threshold, the network device may notify the terminal to stop performing cell measurements of M cells through the second indication information, for example, the M cells include cells for transmitting system information except the first cell, so as to reduce unnecessary power overhead. Or, if the cell measurement performed by the terminal in S502 also measures the signal quality of the serving cell, the network device determines that the signal quality of the system information cell and the signal quality of the serving cell are both better, and the network device may send the second indication information to the terminal. However, the present application is not limited thereto.
In yet another embodiment, the network device sends another measurement configuration information to the terminal, for example, the measurement configuration information sent by the network device to the terminal in S501 is measurement configuration information 1, and after receiving the measurement report associated with measurement configuration information 1, the network device sends measurement configuration information 2 to the terminal based on the measurement report. The measurement configuration information 2 includes measurement object information indicating that the measurement object of the measurement configuration includes a set of cells transmitting second cell system information. Optionally, the measurement object further comprises a first cell and/or a second cell.
For example, if the network device determines that the signal quality of the current system information cell (i.e. the first cell) is poor according to the measurement report of the terminal, the network device may configure the terminal to further measure cells transmitting system information except the first cell through the measurement configuration information 2, so that the network device may determine other system information cells that can be changed by the terminal. By the scheme, the network equipment can firstly configure the terminal to measure a small number of cells, such as the current system information cell and/or the service cell, and can configure the terminal to measure the adjacent cells to select a proper cell under the condition that the network equipment judges the signal quality of the current system information cell and/or the signal quality of the service cell is reduced based on the measurement report of the terminal. The unnecessary measurement and reporting power consumption of the terminal can be reduced, and the efficiency of mobility management is improved.

Optionally, the measurement object indicated by the measurement object information comprises a set of cells transmitting system information of CCC1 cells, the set of cells comprising BCC2 cells. At least one cell measured by the UE in S605 includes the set of cells indicated by the measurement object information.
The network device indicates a cell transmitting system information of the second cell through the measurement object information, and the terminal may determine a cell transmitting system information of the second cell, i.e., a system information cell, based on the measurement object information, so that the terminal may determine whether an event related to the measurement result of the system information cell occurs or stops based on the measurement result of the system information cell.
For example, the measurement configuration information sent by the CCC1 cell in S604 is measurement configuration information 2, the CCC1 cell also sends measurement configuration information 1 to the terminal before S604, after receiving the measurement report associated with the measurement configuration information 1, based on the measurement report, the network device determines that the signal quality of the current system information cell (i.e., the first cell) is poor, and then the network device sends the measurement configuration information 2 to the terminal, where the measurement configuration information 2 configures a set of cells whose measurement objects include system information for transmitting the CCC1 cell. So that the network device can determine other system information cells that the terminal can change. But the present application is not limited thereto.

After receiving the measurement report from the UE, the CCC1 cell determines to change the serving cell of the UE and/or determines to change the cell receiving the system information according to the measurement result of at least one cell reported by the UE in the measurement report.
For example, the CCC1 cell may determine that the signal quality of the BCC2 cell is higher than the signal quality of the BCC1 cell according to the measurement report of the UE, and determine to change the cell in which the UE receives the system information from the BCC1 cell to the BCC2 cell. Alternatively, the CCC1 cell determines to change the serving cell of the UE.

The network equipment determines that the signal quality of the system information cell (i.e. the first cell) of the UE is better according to the measurement report of the UE, if the signal quality is higher than a preset threshold, the network equipment can inform the UE to stop cell measurement through the second indication information so as to reduce unnecessary power expenditure. Or, if the cell measurement also measures the signal quality of the serving cell, the network device determines that the signal quality of the system information cell and the signal quality of the serving cell are better, and the network device may send the second indication information to the UE. However, the present application is not limited thereto.
