All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that the terms "comprises" and "comprising," along with their variants, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
With the progress of network communication technology, the service rate supported by the network is higher and higher, the terminal density is higher and higher, the network capacity is obviously improved, the complexity of network equipment is improved by times, the number of network access points is increased, the number of cells with overlapped coverage and heterogeneous networking is increased, the interference is increased and the energy consumption of the equipment is increased.
Closing the network access point during the idle period of the service can save energy consumption, for example, actively closing the equipment units of the idle cell in late night according to the tidal effect, and opening the equipment units until the load is increased in early morning. However, if all network access points in an area are closed at the same time to save energy and reduce consumption, network coverage holes and insufficient capacity of hot spot areas may be caused; if the partial frequency bands of all network access points in an area are synchronously reduced, the interference and energy-saving effects are not reduced, the burst service requirements of local users cannot be met, if the network access points cannot be timely evoked, the access time delay and the switching time delay of the users are larger, and the service experience of the users is greatly influenced by the limited service bandwidth.
Based on this, the embodiment of the application provides a network access point control method capable of reducing energy consumption, and after the position information and/or service information of the terminal equipment are obtained, at least one network access point can be controlled to enter an awake state or a dormant state based on the position information and/or service information of the terminal equipment, so that the network access point entering the awake state provides service for the terminal equipment. According to the mode, at least one network access point can be synchronously controlled to enter an awake state or a dormant state according to the position information and/or service information of the terminal equipment, namely, the network access point can be in the dormant state when the terminal equipment is not needed, the requirement of reducing energy consumption is met, and the network access point can be awakened in time when the terminal equipment is required, so that the service quality of a communication network is ensured.
Fig. 1 shows a schematic structural diagram of a network access point control system, and as shown in fig. 1, the network access point control system includes a network side device 110, a network access point 120, and a terminal device 130.
The network-side device 110 includes a Centralized Unit (CU) and/or a Distributed Unit (DU), among others. Taking fig. 1 as an example, the network-side device may be a centralized unit 111, a distributed unit 112, and a distributed unit 113. Wherein one CU may be connected to a plurality of DUs, and one DU may be connected to a plurality of network access points.
The network side device 110 may store the following information: the method comprises the steps of controlling position information of each network access point by network side equipment, adjacent relation among each network access point, historical grouping information of each network access point and switching scheduling information of each network access point.
If the network side device is a CU, location information of the distributed units DU to which each network access point belongs is also stored. If the network side device is a DU, it may also store its own location information.
The network Access Point 120 provided in the embodiment of the present application may be a wireless Access Point (AP), a transmission and reception Point (Transmission Receiption Point, TRP), a Relay (Relay) device, or a terminal device.
The network access point 120 may be divided into an awake state and a sleep state, and the network access point in the sleep state may be divided into the following three states, specifically as follows:
first sleep state: the network access point in the first sleep state only receives signals or instructions sent by the network side equipment, does not transmit wireless signals, and does not receive terminal signals.
Second sleep state: the network access point in the second dormancy state receives the signal or instruction sent by the network side device, receives the service information sent by the terminal device and reports the received service information to the network side device.
The network access point in the second sleep state may switch itself from the sleep state to the wake state based on the service information after receiving the service information sent by the terminal device, or may wake any other network access point in the sleep state based on the service quality of the communication network.
Third sleep state: the network access point in the third sleep state periodically transmits a preconfigured first probe signal through radio frequency and turns off the radio frequency transmission function at a time other than the time of transmitting the first probe signal.
The network access point in the third sleep state may be further divided into a network access point that turns on the radio frequency receiving function and a network access point that turns off the radio frequency receiving function.
In a possible implementation manner, the network side device 110 obtains location information and/or service information of the terminal device 130; at least one network access point 120 is controlled to enter an awake state or a sleep state according to location information and/or service information of the terminal device 130, so that the network access point 120 entering the awake state provides service for the terminal device.
The position information of the terminal equipment is three-dimensional geographic coordinate information of the terminal equipment, and the three-dimensional geographic coordinate information can be longitude and latitude of the position of the terminal equipment, elevation coordinate information of the position of the terminal equipment and the like.
The network access point provides service for the terminal device, which may be that the network access point provides resources needed in the communication process for the terminal device. The resources may be communication resources, computing resources, storage resources, etc.
The network side device 110 may send a wake-up instruction or a sleep instruction to the at least one network access point 120 according to the location information and/or the service information of the terminal device.
The wake-up instruction is used for indicating the corresponding network access point to enter a wake-up state; the dormancy instruction is used for indicating the corresponding network access point to enter a dormancy state.
The wake-up instruction includes: node identification of the network access point indicated by the wake-up instruction, wireless port resource information, frequency point resource information and time slot resource information. The sleep instruction includes: node identification of the network access point indicated by the dormancy instruction, wireless port resource information, frequency point resource information and time slot resource information.
In another possible implementation manner, the network access point also sends a wake-up instruction to at least one other network access point according to the location information and/or service information of the terminal device, or switches from the sleep state to the wake-up state according to the location information and/or service information of the terminal device.
When the network access point is in a state capable of acquiring the position information and/or service information of the terminal equipment, the network access point can automatically decide whether to switch itself from the sleep state to the wake state after acquiring the position information and/or service information of the terminal equipment. And a wake-up instruction can be sent to other network access points, so that the other network access points are waken up to serve the terminal equipment, and the service quality of the terminal equipment is ensured. Specifically, the network access point in the wake-up state may be a network access point in the second sleep state, where the network access point has a function of waking up itself or waking up other network access points, so that the network access point in the sleep state may be woken up more quickly, and service is provided for the terminal device. In one embodiment, the network access point is not provided with functionality to instruct other network access points to enter a dormant state.
In a possible embodiment, taking an AP in the second sleep state as an example, if the AP in the second sleep state obtains service information and/or location information of the terminal device, a wake-up instruction may be sent to at least one network access point based on the service information and/or location information of the terminal device; or switching the second sleep state of the communication unit to the wake-up state, and waking up all communication units of the communication unit.
It should be noted that the network access point control system shown in fig. 1 is merely an exemplary structure, and the network access point in fig. 1 may be a TRP or an AP.
In other embodiments, the network access point control system provided in the embodiments of the present application may have other structures. For example, the network access point control system comprises only the centralized unit CU and the network access points. Here, the network access point may be an AP. Wherein one CU may be connected with a plurality of APs. The AP may have a function of the distributed unit DU in the example of fig. 1 or may have a function of the terminal device.
The network access point control system provided by the embodiment of the application can put the network access point into a dormant state in an idle period, and turn off part of communication resources to reduce interference and keep energy conservation. And when the terminal equipment needs to be served, the network access points can be awakened timely, and a plurality of network access points form a flexible cell to serve the terminal equipment, so that the service quality of the communication network is ensured.
The wake-up network access point is described based on the location information and/or service information of the terminal device according to the following embodiments, and specific implementation manners are as follows: the network access points in the following embodiments are all exemplified by TRP.
Example 1: and the terminal actively accesses a process, wherein the connection relation of each device is shown in fig. 3, and the specific interaction process of each device is shown in fig. 2.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 3, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. Wherein TRP2, TRP4, TRP5, TRP6 are all in a first dormant state; TRP1, TRP3, TRP7, TRP8 are in a third dormant state and the UE represents a terminal device.
The interaction process between the devices in the network access point control system is shown in fig. 2, and includes the following steps: in the interaction process shown in fig. 2, the probe signals transmitted by the terminal device outwards are all exemplified by random access requests.
Step 201: the terminal device transmits a random access request to the outside.
Step 202: TRP3 and TRP8 receive a random access request transmitted from a terminal device.
Step 203: TRP3 reports the received random access request to DU1, TRP8 reports the received random access request to DU2.
Step 204: DU1 reports the random access request to the CU, and DU2 reports the random access request to the CU.
Step 205: the CU establishes a connection with the terminal device.
Step 206: the CU informs the DU1 and DU2 to provide the service for the terminal device.
Step 207: DU1 turns on all communication units of TRP 3; DU2 turns on all communication units of TRP 8.
Step 208: DU1 sends a wake-up instruction to TRP3 and DU2 sends a wake-up instruction to TRP 8.
Specifically, TRP3 and TRP8 in the third sleep state may receive a random access request sent by the terminal device and establish a connection with the terminal device. TRP1 and TRP7 do not receive the random access request from the terminal device since they are far from the terminal device. Since TRP2, TRP4, TRP5, TRP6 in the first sleep state receives only the command transmitted from the upper stage, the random access request from the terminal device is not received at this time.
TRP3 and TRP8, which received the random access request, report the received random access request to the corresponding distributed unit DU. After receiving the random access request sent by TRP3, DU1 determines to turn on all communication units of TRP3, sends a wake-up instruction to TRP3, and DU2 determines to turn on all communication units of TRP8, and sends a wake-up instruction to TRP 8.
After the process is finished, TRP8 and TRP3 completely start all communication units to provide service for terminal equipment.
Step 209: the terminal device reports the location information to the DU 1.
Specifically, if the terminal device has the positioning function, the terminal device may report its own location information to the network side device, for example, report its own location information to the DU1, report its own location information to the DU2, or report its own location information to the CU. Here, DU1 is taken as an example.
Optionally, the terminal device may also report its own location information to the network access point, and in step 209, the terminal device may report its own location information together with step 201, and report the location information of the terminal device while sending out the random access request. The location information of the terminal device may also be carried when the random access request is sent. Finally, the TRP node which can establish connection with the terminal equipment can be reported to the corresponding network side equipment.
Step 210: the DU1 determines to turn on all communication units of TRP4 according to the received location information of the terminal device and the location information of TRP.
Step 211: DU1 sends a wake-up instruction to TRP 4.
Step 212: after receiving the wake-up instruction, TRP4 is in a wake-up state.
The network side device determines at least one network access point capable of providing service for the terminal device according to the position information and/or service information of the terminal device, and sends a wake-up instruction to the at least one network access point.
Specifically, the network side device DU1 further directly determines at least one network access point capable of providing a service for the terminal device based on the location information of the terminal device and the location information of each TRP node. In step S210, it is directly determined that the TRP node capable of providing the best quality service for the terminal device is TRP4, or alternatively, TRP4 may be selected based on TRP nodes within a preset range of the terminal device, after it is determined that TRP4 needs to be awakened, all communication units of TRP4 are directly turned on, and an awakening instruction is sent to TRP 4. The preset range of the terminal device can be understood as region 1 as shown in fig. 3.
Further, before waking up other network access points, the network side device may also determine whether the available resources provided by the TRP serving the terminal device at this time meet the service requirement of the terminal device. The specific implementation mode is as follows:
optionally, if it is determined, based on the service information reported by the terminal device, that the service provided by the connected network access point currently connected to the terminal device for the terminal device can meet the service requirement of the terminal device, then it may not be necessary to wake up a new network access point.
Optionally, if it is determined, based on the service information reported by the terminal device, that the service provided by the connected network access point currently connected to the terminal device for the terminal device cannot meet the service requirement of the terminal device, at least one candidate network access point in a preset range around the terminal device and in a wake-up state may be determined based on the location information of the terminal device and the location information of each network access point.
The candidate network access points in the awake state within the area 1 given in fig. 3 are determined, illustratively, based on the location information of the terminal device.
Optionally, if the service provided by the at least one candidate network access point for the terminal device can meet the service requirement of the terminal device, the at least one candidate network access point is used as a network access point of the terminal device on the network access side.
Optionally, if the service provided by the connected network access point and the candidate network access point for the terminal device cannot meet the service requirement of the terminal device, based on the location information of the terminal device, sending a wake-up instruction to at least one network access point in a preset range around the terminal device and in a dormant state.
For example, as shown in fig. 3, if there is no candidate network access point in the awake state in the area 1 and no connection is established with the terminal device, then the network access point in the sleep state may be awake. As shown in step 210 and step 211.
Through the above process, after TRP4 is awakened, it is in an awake state, and the next step can be performed.
Step 213: the CU groups TRP3, TRP8, TRP4 into TRP groups.
Step 214: the CU sends reconfiguration information to the terminal device.
Step 215: the terminal device establishes a connection with TRP4 based on the reconfiguration information.
Specifically, based on the steps 213-215, after TRP4 is in the awake state, the TRP nodes needed to serve the terminal device include three TRP3, TRP4, TRP8, which belong to two different distributed units, so that the TRP3, TRP4, TRP8 nodes are formed into one TRP group by the CU to serve the terminal device. The connection between TRP3 and TRP8 and the terminal equipment is established, at this time, the connection between TRP4 and the terminal equipment is also required, the CU informs the terminal equipment of the identification information and the resource configuration information of the TRP4 in a mode of controlling RRC reconfiguration information by radio resources, after the terminal equipment receives the reconfiguration information, the identification information and the resource configuration information of the TRP4 can be acquired based on the reconfiguration information, and the connection between the terminal equipment and the TRP4 can be established, at this time, the TRP3, the TRP4 and the TRP8 form a TRP group which can be understood as a flexible cell for providing service for the terminal equipment.
Further, the process of waking up TRP4 in the above steps is determined by the network side device according to the location information of the terminal device and the location information of each network access point controlled by the network side device. The location information of the terminal device may be location information reported by the terminal device, and the terminal device as provided in embodiment 1 has a positioning function, and may report its location information to the network side device. However, some terminal devices do not have a positioning function, and cannot report their own position information, and the position information of the terminal device may be determined according to service information of the terminal device.
The following are embodiments of determining location information of a terminal device that does not have a positioning function:
mode 1: and determining the position information of the terminal equipment according to the position information of the connected network access point which receives the connection establishment request of the terminal equipment.
Mode 2: and determining the connected network access point currently connected with the terminal equipment according to the signal measurement result of the terminal equipment, and determining the position information of the terminal equipment according to the position information of the connected network access point. The signal measurement result contains information of the connected network access point connected with the terminal equipment currently.
Mode 3: the network side equipment receives the position information of the terminal equipment sent by the position sensing network access point with the terminal position sensing function.
The location information of the terminal equipment is determined by the location-aware network access point according to the detection signal sent by the terminal equipment.
The location information of each network access point controlled by the network side device used in the above process is stored in the network side device, or is determined by the network side device according to at least one of the stored information: the method comprises the steps of adjacent relation among network access points, historical grouping information of the network access points, switching scheduling information of the network access points and position information of a distributed unit DU to which the network access points belong.
In one possible embodiment, in step 210-step 212, if the DU1 determines that TRP5 is to be woken up, not TRP4, based on the location information of each TRP node after receiving the location information of the terminal device, then the DU1 cannot directly send a wake-up command to TRP5 to directly wake up TRP 5.
If the DU1 wants to wake up to serve the terminal device for TRP5, the specific implementation manner may be as follows:
mode 1: the DU1 may send information to the CU, instruct the DU2 to send a wake-up instruction to the TRP5 through the CU, and after the DU2 receives the instruction from the CU, determine whether the TRP5 needs to wake up.
Mode 2: a communication interface may exist between DU1 and DU2, through which DU1 may inform DU2 that TRP5 needs to be awakened.
Example 2: and a passive terminal access process, wherein the connection relation of each device is shown in fig. 5, and the specific interaction process of each device is shown in fig. 4.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 5, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. Wherein TRP2, TRP4, TRP5, TRP7 are all in a first dormant state; TRP1, TRP3, TRP8 are in a third dormant state. TRP6 is in a second sleep state. The UE means a terminal device.
The interaction process between the devices in the network access point control system is shown in fig. 4, and includes the following steps:
step 401: the CU receives paging information for the UE.
Specifically, the CU may receive paging information for the UE sent by the core network.
Step 402: paging information of the UE is issued to the DU1 and the DU 2.
Step 403: the method comprises the steps that DU1 receives paging information aiming at UE and issued by CU, and the paging information of the UE is issued to TRP to which the DU1 belongs; the DU2 receives paging information for the UE issued by the CU, and issues the paging information of the UE to the TRP to which the DU2 belongs.
Specifically, when paging information of the UE is issued, the DU1 and the DU2 transmit the paging information for the UE to all TRPs, and only TRP1 to which the DU1 belongs and TRP6 and TRP7 to which the UE belongs are exemplified in fig. 4.
Step 404: the UE establishes a connection with TRP 6.
Specifically, TRP6 transmits paging information for UE to UE after receiving paging information for UE issued by DU 2. After receiving the paging information, the UE further sends a connection establishment request to the TRP6, and after receiving the connection establishment request of the UE, the TRP6 may switch itself from the sleep state to the awake state based on the connection establishment request of the UE, and establish a connection relationship with the UE.
TRP7, after receiving the paging information, can only receive the signal sent thereto by the network side device because it is in the first sleep state, and shuts down most of the communication units and the computing units. Therefore, even if paging information is received, a wake-up instruction to turn on all communication units is not received, and connection cannot be established with the UE.
TRP1 did not successfully establish a connection with the UE.
Step 405: TRP6 reports the traffic information of the UE to DU 2.
Specifically, after TRP6 establishes connection with UE, reporting service request of UE to network side equipment to which TRP6 belongs
Step 406: the UE reports the location information to DU 2.
Step 407: DU2 determines wake-up TRP7 according to service information and/or location information of the UE and location information of each TRP, and starts all communication units of TRP 7.
Step 408: DU2 sends a wake-up instruction to TRP 7.
Step 409: after receiving the wake-up instruction, TRP7 starts all communication units of the communication unit.
Step 410: DU2 transmits measurement configuration information of TRP7 to TRP 6.
Wherein the measurement configuration information includes frequency point information of TRP 7.
Step 411: TRP6 transmits measurement configuration information of TRP7 to UE.
Step 412: the UE establishes a connection with TRP 7.
Step 413: the UE measures the signals of TRP6 and TRP7 and reports the signal measurement results of TRP6 and TRP7 to the DU 2.
The DU2 schedules resources of TRP6 and TRP7 to provide a traffic service for the UE based on the signal measurement result.
Both the above embodiment 1 and embodiment 2 are processes of terminal access. Based on the embodiments 1 and 2 provided by the present application, it can be seen that after the network access point control system obtains the service information and/or the location information of the terminal device, a flexible cell for providing service for the terminal device can be formed. And the flexible cell of the type can form a new flexible cell along with the change condition of the service information and/or the position information reported by the terminal equipment, namely the service requirement condition of the terminal equipment, so as to ensure that at least one network access point which is enough to meet the service requirement of the terminal equipment and ensure the service quality of a communication network exists in the preset range of the terminal equipment all the time.
Example 3: the terminal movement causes a handover procedure in which the connection relationship of the respective devices is shown in fig. 7 and the specific interaction procedure of the respective devices is shown in fig. 6.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 7, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. In the initial state, the terminal equipment UE communicates with TRP3 and TRP4, TRP1, TRP2 and TRP8 are in a wake-up state, and periodically transmit broadcast signals, and TRP5 is in a sleep state. The arrow points in a direction of movement denoted as terminal device. The terminal device UE communicating with TRP3 and TRP4 may be understood as the current TRP3 and TRP4 constituting the TRP group providing the service to the terminal device.
The interaction process between the devices in the network access point control system is shown in fig. 6, and includes the following steps:
step 601: and the terminal equipment reports the signal measurement result of the current TRP group in the moving process.
Step 602: the network side device determines a signal quality reduction between the current TRP group and the terminal device based on the signal measurement result of the current TRP group.
Specifically, since the terminal device moves away from a certain TRP in the current TRP group, the signal quality between this TRP and the terminal device is reduced, and the signal is deteriorated. The network side device can determine which signal between the TRP and the terminal device is degraded specifically according to the signal measurement result of the current TRP group.
Further, according to the location information of the terminal device, the network side device may send an instruction to the TRP connected to the terminal device, but with poor signal quality displayed in the signal measurement result, to disconnect it from the terminal device. In the interaction process of fig. 6, in the case that the signal quality between TRP4 and the terminal device is reduced, but not reduced too much, the connection between TRP4 and the terminal device is not required to be disconnected temporarily, and as the terminal device moves in the moving direction of fig. 7, the network side device can disconnect the connection between the terminal device and TRP 4.
Due to the signal degradation, the quality of service provided by the communication network to the terminal device is reduced, new TRP needs to be added to provide resources for the terminal device, and then the subsequent steps can be executed.
Step 603: and transmitting measurement configuration information of TRP1, TRP2 and TRP8 to the terminal equipment.
Specifically, the network side device may send measurement configuration information of the TRP node located in a certain area of the terminal device and in an awake state to the terminal device. The certain area may not be within a preset range of the terminal device, so the TRP nodes may be TRP1, TRP2, TRP8. The measurement configuration information comprises measurement frequency point information.
In the process, the terminal equipment reports the position information of the terminal equipment to the network side equipment in real time in the communication process, or the network side equipment determines the position information of the terminal equipment based on the position information of each TRP.
Step 604: and the terminal equipment reports signal measurement results of TRP1, TRP2 and TRP8 to the network side equipment.
Step 605: the network side equipment determines that the service provided by TRP1, TRP2 and TRP8 can not meet the service requirement of the terminal equipment based on the signal measurement result.
Optionally, if the network side device determines that the service provided by TRP1, TRP2, TRP8 can meet the service requirement of the terminal device based on the signal measurement result. The network side equipment can send the reconfiguration information of TRP1, TRP2 and TRP8 to the terminal equipment again, and after the terminal equipment receives the reconfiguration information, the network side equipment can establish connection with TRP1, TRP2 and TRP8 to form a new TRP group by using TRP1, TRP2, TRP8, TRP3 and TRP 4.
If only one TRP of the TRP8 can meet the service requirement of the terminal equipment for the service provided by the terminal equipment, the network side equipment can send reconfiguration information of the TRP8 to the terminal equipment again so as to enable the TRP8 to establish a connection relationship with the terminal equipment, provide the service for the terminal equipment and form a new TRP group by the TRP8, the TRP3 and the TRP 4.
If step 605, step 606 is continued.
Step 606: the network side equipment determines TRP5 which wakes up in a preset range of the terminal equipment and is in a dormant state based on the position information of the terminal equipment and the position information of each TRP.
Illustratively, after determining that the service provided by TRP1, TRP2, TRP8 cannot meet the service requirement of the terminal device, TRP5 that wakes up within a preset range around the terminal device and is in a dormant state is determined based on the location information of the terminal device and the location information of each TRP, and the resource information of each TRP.
Two situations can be distinguished:
case 1: after TRP1, TRP2 and TRP8 provide service for the terminal equipment, the service requirement of the terminal equipment is not met, and then TRP1, TRP2, TRP8 and TRP5 are awakened.
Case 2: it is determined that the service provided by TRP1, TRP2, TRP8 cannot meet the service requirement of the terminal device, and the service requirement of the terminal device can be met by providing the service for the terminal device only through TRP5, only TRP5 can be awakened.
The following steps take only wake-up TRP5 of case 2 as an example.
Step 607: a wake-up instruction is sent to TRP 5.
Step 608: TRP5 receives a wake-up instruction and turns on all communication units.
Step 609: the terminal device establishes a connection with TRP 5.
Step 610: the network side equipment forms TRP3, TRP4 and TRP5 into TRP groups.
Further, the above steps are only one interaction process of the terminal device in the moving process, and along with the change of the position information of the terminal device and the signal measurement result of the terminal device acquired by the network side device, the TRP group can be adjusted in real time, and a new TRP is awakened or the TRP with poor signal quality is disconnected from the terminal device, or the terminal device enters a dormant state.
Based on the above embodiment 3, it can be seen that, in the network access point control system provided by the present application, based on the location information of the terminal device and the location information of each network access point, the connection condition between the network access point and the terminal device can be timely controlled, so that the service quality of the terminal device can be ensured, and the network access point which cannot provide better signal quality for the terminal device can be disconnected from the terminal device at any time, thereby saving energy consumption and improving energy efficiency.
The above embodiments 1-3 all send a connection establishment request to the terminal device, thereby triggering the network access point to wake up, and the following embodiments show that the non-connection establishment request also triggers the network access point to wake up. Fig. 8 shows a schematic flow diagram of a network access point wake-up triggered by a non-connection establishment request. The specific procedure is shown by the following examples. The specific steps are as follows: the network access point in the following steps takes TRP as an example.
Step 801: terminal traffic demand change/network load change/TRP failure causes a decrease in traffic quality.
Specifically, when the service requirement of the terminal equipment changes, the terminal equipment reports the new service requirement; the load condition of the network side changes, such as the increase of terminal equipment of TRP3 and TRP4 services subordinate to the distributed unit DU1, or the remarkable improvement of resource loads such as communication/calculation and the like; when the TRP providing the business service for the terminal equipment fails to cause the service quality of the terminal equipment to be reduced or the TRP providing the business service for the terminal equipment is abnormally unavailable, the terminal equipment does not send a connection establishment request at the moment, and the network access point can be awakened.
Step 802: the current TRP group is whether the service provided by the terminal device is sufficient to support the quality of service requirements of the terminal device. If yes, go to step 803; if not, go to step 804.
Specifically, the presence of TRP3 and TRP4 in the current TRP group is exemplified.

Three cases shown in fig. 8 are described by the following examples, which are specifically shown as follows:
example 4: in the case of a change in terminal service demand, the connection relationship of each device is shown in fig. 10, and the specific interaction process of each device is shown in fig. 9.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 10, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. In the initial state, the terminal equipment UE communicates with TRP3 and TRP4, TRP1, TRP2 and TRP8 are in a wake-up state, and periodically transmit broadcast signals, and TRP5 is in a sleep state. The terminal device UE communicating with TRP3 and TRP4 may be understood as the current TRP3 and TRP4 constituting the TRP group providing the service to the terminal device.
The interaction process between the devices in the network access point control system is shown in fig. 9, and includes the following steps:
step 901: the service requirement of the terminal equipment changes, and new service requirements are sent to the network side equipment.
The service requirement changes, for example, the terminal device may be initially a text browsing service and then becomes a video browsing service, and the service requirement of the terminal device increases.
Step 902: the network side equipment determines that the TRP group formed by the current TRP3 and TRP4 is a service provided by the terminal equipment, and cannot meet the new service requirement reported by the terminal equipment.
Optionally, if the current TRP3 and TRP4 provide service for the terminal device, the new service requirement reported by the terminal device can be met, and then resource scheduling is performed from the resource pool corresponding to the current TRP3 and TRP4, so that the service requirement of the terminal device is met by the service services provided by the current TRP3 and TRP4 for the terminal device, and the service quality of the communication network is ensured.
As determined in step 902, when the resources provided by the TRP for the terminal device cannot meet the service requirement of the terminal device, and the situation of insufficient resources occurs, the terminal device needs more resources, and step 903 is performed.
Step 903: the network side equipment transmits measurement configuration information of TRP1, TRP2 and TRP8 to the terminal equipment.
Step 904: and the terminal equipment reports signal measurement results of TRP1, TRP2 and TRP8 to the network side equipment.
Step 905: the network side equipment determines that the service provided by TRP1, TRP2 and TRP8 can not meet the new service requirement based on the signal measurement result.
Optionally, if it is determined that the service provided by all of TRP1, TRP2, TRP8 can meet the new service requirement of the terminal device, the network side device may send the reconfiguration information of TRP1, TRP2, TRP8 to the terminal device again, and after the reconfiguration information is received by the terminal device, the network side device may establish a connection with TRP1, TRP2, TRP8, and form a new TRP group from TRP1, TRP2, TRP8, TRP3, and TRP 4.
If only one TRP of TRP8 can meet the new service requirement of the terminal equipment for the service provided by the terminal equipment, the network side equipment can send reconfiguration information of the TRP8 to the terminal equipment again so as to enable the TRP8 to establish a connection relationship with the terminal equipment, provide the service for the terminal equipment and form a new TRP group by the TRP8, the TRP3 and the TRP 4.
If step 905 is performed, step 906 is continued.
Step 906: the network side equipment determines TRP5 which wakes up within a preset range of the terminal equipment and is in a dormant state based on the position information of the terminal equipment, the new service requirement and the position information of each TRP.
The network side device determines that TRP5 can provide enough resources to meet the new service requirement reported by the terminal device based on the location information of the terminal device, the new service requirement, the location information of each TRP, and the resource information of each TRP, and then determines to wake up TRP5.
Step 907: a wake-up instruction is sent to TRP 5.
Step 908: TRP5 receives a wake-up instruction and turns on all communication units.
Step 909: the terminal device establishes a connection with TRP 5.
Step 910: the network side equipment forms TRP3, TRP4 and TRP5 into TRP groups.
Example 5: in the case where the network side load changes, the connection relationship of each device is shown in fig. 12, and the specific interaction process of each device is shown in fig. 11.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 12, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. In the initial state, the terminal equipment UE communicates with TRP3 and TRP4, TRP1, TRP2 and TRP8 are in a wake-up state, and periodically transmit broadcast signals, and TRP5 is in a sleep state. The terminal device UE communicating with TRP3 and TRP4 may be understood as the current TRP3 and TRP4 constituting the TRP group providing the service to the terminal device.
The interaction process between the devices in the network access point control system is shown in fig. 11, and includes the following steps:
step 1101: the network side equipment determines that the TRP group formed by the current TRP3 and TRP4 is a service provided by the terminal equipment, and cannot meet the service requirement reported by the terminal equipment.
For example, as the load on the network side changes, if the number of TRP3 and TRP4 services under the distributed unit DU1 increases, or the resource load such as communication/calculation is significantly increased, the network side device determines that the current TRP3 and TRP4 form the TRP group as the service provided by the terminal device, which cannot meet the service requirement reported by the terminal device.
Optionally, if the current TRP group formed by TRP3 and TRP4 is the service provided by the terminal device and can meet the service requirement reported by the terminal device, scheduling resources in the TRP group formed by TRP3 and TRP4 to provide the service for the terminal device.
Step 1102: the network side equipment transmits measurement configuration information of TRP1, TRP2 and TRP8 to the terminal equipment.
Step 1103: and the terminal equipment reports signal measurement results of TRP1, TRP2 and TRP8 to the network side equipment.
Step 1104: the network side equipment determines that the service provided by TRP1, TRP2 and TRP8 can not meet the service requirement of the terminal equipment based on the signal measurement result.
Optionally, if it is determined that all the service provided by TRP1, TRP2, TRP8 can meet the service requirement of the terminal device, the network side device sends reconfiguration information to the terminal device, and the terminal device can establish connection with TRP1, TRP2, TRP8, TRP3, TRP4 to form a new TRP group.
If only one TRP of TRP8 can meet the service requirement of the terminal equipment for the service provided by the terminal equipment, the network side equipment can send reconfiguration information of the TRP8 to the terminal equipment so as to enable the TRP8 to establish a connection relationship with the terminal equipment to provide the service for the terminal equipment, and form a new TRP group by the TRP8, the TRP3 and the TRP 4.
Step 1105: the network side equipment determines TRP5 which wakes up in a preset range of the terminal equipment and is in a dormant state based on the position information of the terminal equipment, the service requirement and the position information of each TRP.
Illustratively, after waking up TRP5, the service provided for the terminal device may satisfy the service requirement of the terminal device.
Step 1106: a wake-up instruction is sent to TRP5.
Step 1107: TRP5 receives a wake-up instruction and turns on all communication units.
Step 1108: the terminal device establishes a connection with TRP5.
Step 1109: the network side equipment forms TRP3, TRP4 and TRP5 into TRP groups.
Example 6: a case where TRP malfunctions to cause a decrease in service quality, in which case the connection relationship of the respective devices is shown in fig. 14 and the specific interaction process of the respective devices is shown in fig. 13.
For ease of understanding, the connection relationship between the devices in the network access point control system will be described first. As shown in fig. 14, the network access point control system may include one CU, which connects two DUs, DU1 is connected to TRP1 to TRP4, and DU2 is connected to TRP5 to TRP 8. In the initial state, the terminal equipment UE communicates with TRP3, TRP4 and TRP8, TRP1 and TRP2 are in a wake-up state, and periodically transmit broadcast signals, and TRP5 is in a sleep state. The communication between the terminal equipment UE and TRP3, TRP4 and TRP8 can be understood that the current TRP3, TRP4 and TRP8 form a TRP group to provide the service for the terminal equipment.
The interaction process between the devices in the network access point control system is shown in fig. 13, and includes the following steps:
step 1301: the network side device sends reconfiguration information to the terminal device indicating that TRP8 is removed from the current TRP group serving the terminal device.
Illustratively, the current TRP3, TRP4, and TRP8 composition TRP group may be referred to as the current TRP group. Taking TRP8 failure or unavailable TRP8 resources as an example, since TRP8 can reduce the service provided to the terminal device, resulting in a reduction in the quality of service provided to the terminal device, the network side device can remove TRP8 after determining that TRP8 fails or TRP8 resources are unavailable.
Step 1302: the network side equipment determines that the rest TRP3 and TRP4 form a TRP group to provide service for the terminal equipment, and the service requirement of the terminal equipment cannot be met.
For example, after TRP8 is removed, the network side device may determine whether the remaining TRP3 and TRP4 form a service provided by the TRP group for the terminal device, and whether the service requirement of the terminal device is met.
If yes, scheduling resources in the TRP group consisting of the rest TRP3 and TRP 4.
Step 1303: the network side equipment transmits measurement configuration information of TRP1 and TRP2 to the terminal equipment.
Step 1304: and the terminal equipment reports signal measurement results of the TRP1 and the TRP2 to the network side equipment.
Step 1305: the network side equipment determines that the service provided by TRP1 and TRP2 can not meet the service requirement based on the signal measurement result.
Optionally, if it is determined that the service provided by TRP1 and TRP2 can meet the service requirement of the terminal device, the network side device sends reconfiguration information to the terminal device, and the terminal device can establish connection with TRP1 and TRP2 to form a new TRP group by TRP1, TRP2, TRP3 and TRP 4.
If only one TRP of TRP1 can meet the service requirement of the terminal equipment for the service provided by the terminal equipment, the network side equipment can send reconfiguration information of the TRP1 to the terminal equipment so as to enable the TRP1 to establish a connection relationship with the terminal equipment, provide the service for the terminal equipment and form a new TRP group by the TRP1, the TRP3 and the TRP 4.
Step 1306: the network side equipment determines TRP5 which wakes up in a preset range of the terminal equipment and is in a dormant state based on the position information of the terminal equipment, the service requirement and the position information of each TRP.
Illustratively, after waking up TRP5, the service provided for the terminal device may satisfy the service requirement of the terminal device.
Step 1307: a wake-up instruction is sent to TRP 5.
Step 1308: TRP5 receives a wake-up instruction and turns on all communication units.
Step 1309: the terminal device establishes a connection with TRP 5.
Step 1310: the network side equipment forms TRP3, TRP4 and TRP5 into TRP groups.
It should be noted that, in the above steps, it is also possible to first determine which network access point is added to the current TRP group, and after determining that TRP5 is added to the current TRP group to form a new TRP group enough to satisfy the service requirement of the terminal device, remove TRP8 from the current TRP group. And the instruction information for adding the TRP5 to the current TRP group and the instruction for removing the TRP8 from the current TRP group can be sent to the terminal equipment together, so that the TRP8 can be utilized to temporarily provide service for the terminal equipment, the service quality of the communication network to the terminal equipment is not reduced too much, the communication resource sent to the terminal equipment by the network side equipment can be saved, and the energy consumption is reduced.
Based on the above embodiments 4-6, it can be seen that, when the service requirement of the terminal device changes, or the load on the network side changes, or the TRP fails to cause abnormal situations such as a decrease in service quality or unavailable TRP resources, the connection condition between the network access point and the terminal device can be timely controlled, so as to ensure that the service requirement of the terminal device can be met, ensure the service quality of the terminal device, and disconnect the network access point and the terminal device, which cannot provide better signal quality for the terminal device, at any time, thereby saving energy consumption and improving energy efficiency.
