As illustrated in
At step S110, a first indication from a UE is obtained, in which the first indication indicates whether the UE supports positioning in a Radio Resource Control (RRC) non-connected state.
The access network device may be various types of base stations. These base stations include, but are not limited to, an eNB or a gNB.
After receiving the first indication, the access network device may determine whether the UE supports positioning in the RRC non-connected state. The RRC non-connected state includes, but is not limited to, an RRC idle state and/or an RRC inactive state. For example, the first indication at least indicates a positioning capability of the UE in the RRC inactive state.
After being aware of whether the UE supports positioning in the RRC non-connected state, the access network device may adaptively perform positioning-related configurations and other processing for the UE that is in the RRC non-connected state.
The first indication may indicate a capability related to the positioning performed by the UE in the RRC non-connected state based on a mobile communication signal. For example, the first indication may indicate whether the UE in the RRC non-connected state may send an uplink positioning reference signal, whether the UE in the RRC non-connected state may receive a downlink positioning reference signal, or whether the UE in the RRC non-connected state may report positioning data related to the reception and transmission based on a positioning signal.
In an embodiment, the first indication n is determined by a Location Management Function (LMF) based on information on whether the UE supports positioning in the RRC non-connected state sent by the UE to the LMF and is sent by the LMF to an access network device (e.g., a base station).
In another embodiment, the first indication is sent by the UE to the LMF, and then sent by the LMF to the access network device (e.g., a base station).
In still another embodiment, the first indication is sent by the UE directly to the access network device.
As illustrated in
At step S120, in response to determining that the UE supports to send an uplink positioning reference signal in an RRC non-connected state, an RRC release message including an uplink positioning signal configuration is sent to the UE.
The uplink positioning reference signal configuration is configuration information for the UE to send the uplink positioning reference signal, which indicates, but is not limited to, at least one of the following:
For example, it may be determined, based on the first indication in preceding embodiments, that the UE supports to send the uplink positioning reference signal in the RRC non-connected state, or it may be determined by other means that the UE supports to send the uplink positioning reference signal in the RRC non-connected state. That is, in embodiments of the disclosure, the access network device may determine, based on the first indication sent by the UE, whether the UE supports positioning in the RRC non-connected state. That is, the step S120 may be performed together with the step S110. Certainly, the step S120 may also be executed independently, i.e., the access network device may determine, by any other means, whether the UE supports the positioning in the RRC non-connected state.
For example, when the UE enters the RRC non-connected state or the UE is currently in the RRC non-connected state, if the UE in the RRC non-connected state supports the positioning and the base station sends the uplink positioning signal configuration through an RRC release message, then the network (i.e., base station) sends the uplink positioning signal configuration to the UE without triggering the UE to enter an RRC connected state. In this way, unnecessary power consumption of the UE caused by switching, due to the reception of the uplink positioning signal configuration, from the RRC non-connected state to the RRC connected state may be reduced, which saves the power consumption of the UE, extends the standby time of the UE, and reduces the positioning delay.
As illustrated in
At step S131, in response to determining that the UE does not support to send the uplink positioning reference signal in the RRC non-connected state, the UE in the RRC non-connected state is instructed to enter an RRC connected state.
At step S132, an RRC reconfiguration message including the uplink positioning signal configuration is sent to the UE in the RRC connected state.
For example, if the UE does not support to send the uplink positioning reference signal in an RRC non-connected state, when the base station needs to send the uplink positioning reference signal configuration to the UE, the base station will send an indication to the UE, in which the indication triggers the UE to enter the RRC connected state. After the UE enters the RRC connected state, the base station sends the uplink positioning reference signal configuration to the UE in the RRC connected state.
In detail, the uplink positioning reference signal configuration may be carried in any message sent by the base station to the UE. For example, the uplink positioning reference signal configuration may be carried in an RRC reconfiguration message.
In some embodiments, the first indication indicates at least one of the following:
In some embodiments, indication contents of the first indication may be at least one of the above.
The uplink positioning reference signal includes, but is not limited to, a Sounding Reference Signal (SRS). The received Positioning Reference Signal (PRS).
If the UE in the RRC non-connected state sends the positioning data using the SDT manner, the UE may stay in the RRC non-connected state to send the positioning data to the network side. As an example, the positioning data sent through the SDT manner may be sent to the network side on uplink scheduling grant resources. As another example, the UE may send the positioning data to the network side in the SDT manner by carrying the positioning data in a random access request message A or a random access request message 3.
In some embodiments, obtaining the first indication from the UE includes:
The first indication may come from the LMF. For example, after the LMF has known the positioning capability of the UE in the RRC non-connected state, the LMF may send the first indication to the base station to notify the access network device of the positioning capability of the UE in the RRC non-connected state. There are many ways for the LMF to know the positioning capability of the UE in the RRC non-connected state. For example, the LMF may receive, from the UE, positioning capability information for indicating the positioning capability of the UE in the RRC non-connected state or may determine the positioning capability of the UE in the RRC non-connected state by itself based on configuration data from the UE or device type of the UE. The configuration data may be obtained from a User Data Management (UDM).
In another embodiment, the first indication may come from the UE. For example, the UE may report the first indication to the base station when the UE is in an RRC connected state.
The first indication may be carried in any message from the LMF, e.g., a NR Positioning Protocol A (NRPPa) message.
In some embodiments, receiving the indication sent by the LMF includes:
For example, the NRPPa positioning information request message is further used to instruct the access network device to provide the uplink positioning reference signal configuration of the UE to the LMF.
The NRPPa positioning information request message may be a message sent when instructing or requesting the access network device to provide the uplink positioning reference signal configuration of the UE. In this way, a new information element (IE) may be added to the NRPPa positioning information request message to carry the first indication, or remaining bits of the NRPPa positioning information request message may be used to carry the first indication.
In some embodiments, receiving the indication from the UE includes:
For example, if the UE needs to send the first indication, the UE in the RRC non-connected state may send the first indication through the connection resume request message.
In embodiments of the disclosure, the access network device may determine, based on the first indication sent by the UE, whether the UE supports positioning in the RRC non-connected state. That is, the steps S131 and S132 may be executed together with the step S110. Certainly, the steps S131 and S132 may also be executed independently. That is, the access network device may determine, in any possible way, whether the UE supports positioning in the RRC non-connected state. The steps S131 and S132 may also be executed together with the step S120, or the steps S131 and S132 may be executed together with the step S110 and the step S120.
As illustrated in
At step S210, a second indication sent by UE is received.
The second indication is used to indicate any positioning-related state of the UE.
In an embodiment, the UE may report only the second indication. In another embodiment, the UE may send both the first indication and the second indication to the access network device. If the UE needs to send both the first indication and the second indication to the access network device, the UE may simultaneously report both the first indication and the second indication to the access network device. Certainly, the UE may report the first indication and the second indication to the access network device separately.
In an embodiment, the first indication is determined by the LMF based on the positioning capability sent by the UE to the LMF and then sent to the access network device (e.g., the base station). In another embodiment, the first indication is sent by the UE to the LMF, and then sent by the LMF to the access network device (e.g., the base station). In still another embodiment, the first indication is sent by the UE directly to the access network device.
The second indication may be carried in any uplink message sent by the UE to the access network device. For example, the second indication may be carried in an RRC connection resume request message.
In some embodiments, when the UE sends an event report to the base station, the UE sends the second indication to the access network device. The event report may include, but is not limited to, positioning data. A receiver of the event report is the LMF, and a receiver of the second indication is the access network device (e.g., gNB). For example, the second indication indicates at least one of the following:
When the UE is executing the positioning service or the UE has a service to be executed, and/or the UE needs to report positioning data in the future, and/or the UE has positioning data to be received, the second indication may be used to indicate that the UE needs to stay in the RRC inactive state to complete the positioning service, rather than triggering the UE to enter an RRC idle state where the UE cannot execute the positioning service.
In some embodiments, the method further includes:
If the second indication indicates that the UE has no positioning service to be executed or the UE is not executing the positioning service, and/or the UE has no positioning data to be received, and/or the UE has no positioning data to be sent, the UE may enter an RRC idle state with lower power consumption, and the network-side device may instruct the UE to switch from the RRC inactive state to the RRC idle state.
When the second indication indicates that the UE has a positioning service to be executed, the UE is currently executing a positioning service, the UE has positioning data to be sent, or the UE has positioning data to be received, the UE needs to stay in the RRC inactive state, and the access network device may instruct the UE to stay in the RRC inactive state or not send any indication for changing state to the UE, and thus the UE may stay in the RRC inactive state by default.
For example, the access network device may send an indication to the UE, in which the indication instructs the UE to enter the RRC idle state or stay in the current RRC inactive state.
In some embodiments, instructing the UE to switch from the RRC non-connected state to the RRC idle state or to stay in the RRC non-connected state based on the second indication includes at least one of the following:
In this way, the access network device may indicate whether the UE should continue to stay in the RRC non-connected state based on the received second indication, rather than triggering the UE to enter a state suitable for the current UE. On the one hand, this ensures the smooth execution of the positioning service, and on the other hand, this reduces the power consumption of the UE as much as possible and extends the standby time of the UE.
As illustrated in
At step S310, first indication is sent, in which the first indication indicates whether the UE supports positioning in an RRC non-connected state.
The first indication indicates the positioning capability of the UE in the RRC non-connected state. For example, the first indication is at least used to indicate the positioning capability of the UE in an RRC inactive state.
Embodiments of the disclosure provide a method for processing information, performed by a UE. The method includes:
The positioning capability information at least indicates the positioning capability of the UE in the RRC non-connected state.
Sending the first indication includes:
In an embodiment, the first indication is determined by the LMF based on the positioning capability sent by the UE to the LMF and then sent by the LMF to the access network device (e.g., the base station). In another embodiment, the first indication is sent by the UE to the LMF, and then sent by the LMF to the access network device (e.g., the base station). In still another embodiment, the first indication is sent by the UE directly to the access network device.
In conclusion, the first indication indicates the positioning capability of the UE in the RRC non-connected state, to facilitate the access network device to perform a corresponding operation after receiving the first indication.
In some embodiments, sending the first indication to the LMF includes:
For example, the UE carries the first indication via the LPP message, so that the LMF may receive the first indication based on a LPP protocol.
In some embodiments, the method further includes:
Sending the LPP message including the indication to the LMF includes:
For example, the LMF sends the LPP request message to the UE to instruct the UE to provide information, such as the positioning capability. After receiving the LPP request message, the UE may send the LPP Provide Capability message to the UE based on the LPP request message. Since the LPP Provide Capability message contains the first indication, the LMF, after receiving the LPP Provide Capability message, knows the positioning capability of the UE in the RRC non-connected state.
In some embodiments, sending the first indication to the access network device includes:
If the UE sends the first indication directly to the access network device, the UE may send the connection resume message to the access network device to realize reporting of the first indication.
In some embodiments, the first indication is used to indicate at least one of the following:
As illustrated in
At step S410, a second indication is sent, in which the second indication indicates current positioning-related state information of the UE.
For example, the UE sends the second indication to the LMF or the access network device. If the UE sends the second indication to the LMF, the LMF may transfer the second indication to the access network device.
For example, the second indication indicates at least one of the following:
In some embodiments, the step S410 may be executed together with the step S310 or the step S410 may be executed independently.
If the UE needs to send both the second indication and the first indication to the base station, the first indication and the second indication may be carried in the same message and sent to the access network device to reduce a number of times that the UE sends the message. For example, the UE may send the connection resume message including both the first indication and the second indication to the access network device.
As described above, in an embodiment, the first indication is determined by the LMF based on the positioning capability of the UE and sent by the LMF to the access network device (e.g., the base station).
In another embodiment, the first indication is sent by the UE to the LMF, and then sent by the LMF to the access network device (e.g., the base station).
In still another embodiment, the first indication is sent by the UE directly to the access network device.
In some embodiments, the method further includes the following, as shown in
At step S420, a returned indication is received, in which the indication instructs the UE to enter an RRC idle state or stay in the RRC non-connected state.
In some possible implementations, the returned indication is sent based on the second indication.
For example, the indication may be used to indicate at least one of the following:
In some embodiments, the method further includes:
If the first indication indicates that the UE supports the positioning in an RRC non-connected state or at least in an RRC inactive state, the UE may receive the uplink positioning signal configuration. For example, the UE in the RRC non-connected state may receive the RRC release message carrying the uplink positioning signal configuration.
For example, the uplink positioning signal configuration may at least be used for the UE to send the uplink positioning reference signal in the RRC inactive state.
As illustrated in
At step S510, a first indication is sent to an access network device, in which the first indication indicates whether a UE supports positioning in an RRC non-connected state.
In some embodiments, the first indication is received by the LMF from the UE, or the first indication is generated by the LMF based on the positioning capability of the UE. In detail, the first indication may be generated by the LMF based on positioning capability information for indicating the UE's own positioning capability sent by the UE.
After the first indication is sent to the access network device, the access network device may know whether the UE supports the positioning in the RRC non-connected state. In other words, the access network device may know the positioning capability of the UE in the RRC non-connected state.
In some embodiments, sending the first indication to the access network device includes:
The NRPPa positioning information request message is used to instruct the access network device to provide an uplink positioning reference signal configuration of the UE to the LMF. In this way, the NRPPa positioning information request message not only instructs the access network device to provide the uplink positioning reference signal configuration of the UE, but also notifies the access network device of the positioning capability of the UE in the RRC non-connected state.
In this way, if the access network device did not know the positioning capability of the UE in the RRC non-connected state previously, after the access network device receives the NRPPa positioning information request message, the access network device may know that the UE supports the positioning in the RRC non-connected state, and then the access network device may configure the uplink positioning reference signal for the UE and send the uplink positioning reference signal configuration to the LMF.
In some embodiments, the NRPPa positioning information request message is further used to instruct the access network device to provide the uplink positioning reference signal configuration of the UE to the LMF.
In some embodiments, the first indication is used to indicate at least one of the following:
In some embodiments, the method further includes:
For example, the first indication is received from the UE before sending the first indication to the access network device.
For example, the method further includes:
Sending the LPP message including the indication to the LMF includes:
For example, the LPP messages based on an LPP protocol are exchanged between the UE and the LMF. For example, the UE is instructed by the LPP request message to upload the first indication.
In an embodiment, the method further includes: determining the first indication based on the positioning capability of the UE. For example, the LMF receives the positioning capability information from the UE, and then the LMF generates the first indication by itself based on the positioning capability of the UE indicated by the positioning capability information. Certainly, the LMF may also obtain the positioning capability information that indicates the positioning capability of the UE from other network elements, such as a user database, which is not limited to receiving from the UE.
Embodiments of the disclosure provide a method for positioning a UE in an RRC inactive state. The method includes at least one of the following:
The UE supporting the positioning in the RRC inactive state includes one of the following:
The LMF notifies a base station of the positioning capability through the following message. For example, the LMF notifies, through an NRPPa message, the base station of the positioning capability of the UE in the RRC inactive state.
For example, an NRPPa positioning information request message is used for the LMF to notify the base station of the positioning capability. That is, the LMF may indicate the positioning capability when the LMF requests the uplink positioning reference signal configuration of the UE from the gNB. Or, a new NRPPa positioning message is defined for the LMF to notify the base station of the positioning capability, in which the new NRPPa positioning message may be used to carry the indication indicating the positioning capability of the UE in the RRC inactive state.
The LMF requests, through an LPP message, the indication indicating the positioning capability from the UE.
After the gNB receives the NRPPa message, if the UE may send a SRS in the RRC inactive state, the gNB configures the uplink positioning reference signal configuration for the UE through an RRC release message.
If the UE cannot send a SRS in the RRC inactive state, after the gNB triggers the UE to enter the RRC connected state, the gNB sends the uplink positioning reference signal configuration to the UE through an RRC reconfiguration message.
The UE may provide the indication for indicating the current positioning-related state of the UE to the access network device. For example, the indication may indicate one of the following:
The subsequent data mentioned herein includes, but is not limited to, positioning data.
The indication indicating the current positioning-related state of the UE may be carried by an RRC resume request.
In some embodiments, the indication indicating the current positioning-related state of the UE may also be carried by other messages, e.g., a customized new message.
For example, a location service indication message is defined to send the indication indicating the current positioning-related state of the UE.
If the UE is performing a positioning service or has subsequent data to be sent, the base station will not trigger the UE to enter the RRC idle state, or the base station will require the UE to stay in the RRC idle state.
