Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an information processing method, network side equipment and a terminal.
Background
From the measurement and reporting mode, Minimization Drive Test (MDT) can be classified into the following two types:
first, MDT (logged MDT) is recorded, and User Equipment (UE) in an idle state (ID L E) performs MDT measurement according to logged measurement configuration.
Second, immediate mdt (immediate mdt): CONNECTED (CONNECTED) UEs make MDT measurements according to RRCConnectionReconfiguration. Such UE will report the collected data to the network side instantly. This type is typically applied when the UE is in an active state, in which a connection has been established between the UE and the RAN node.
In the 5G technology, the UE state has an intermediate state, i.e., an INACTIVE state (INACTIVE), in addition to two states, i.e., ID L E and CONNECTED, in the INACTIVE state, a Radio Resource Control (RRC) connection between the UE and the RAN node is released, and when the RRC connection needs to be restored, a connection is established by sending an rrcconnectionresumerrequest carrying a resource identity.
The inactive UE may autonomously change to the ID L E state during the MDT measurement, but there is no scheme in the prior art for how the inactive UE performs the MDT measurement when the state changes.

As shown in fig. 1, the wireless communication system may include: a network side device 11 and a terminal 12. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.
It should be noted that the communication system may include a plurality of terminals, and the network side device may communicate (transmit signaling or transmit data) with the plurality of terminals.
The network side device may be a network side device (e.g., a next generation base station (gNB) or a Transmission and Reception Point (TRP)) in a 5G (Fifth-generation mobile communication technology) system.
The terminal may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, or a Personal Digital Assistant (PDA).
As shown in fig. 2, the information processing method according to the embodiment of the present invention is applied to a terminal, and includes:
step 201, recording first minimization of drive test information, where the first minimization of drive test information includes information related to state transition of the terminal.
Specifically, in the embodiment of the present invention, when the terminal enters the idle state from the inactive state, first minimization of drive test information is recorded, where the first minimization of drive test information includes information related to state transition of the terminal.
The information related to the state transition of the terminal includes one or more of a reason of the state transition, a timestamp, a cell Identification (Identification, ID), a base station Identification, a Wireless L Area Networks (W L AN) Media Access Control (MAC) address, a bluetooth MAC address, location information, and Global Positioning System (GPS) location information.
The reason for the state transition may include any one of: the RRC connection recovery fails, or a CNpaging message is received, or a RAN-based Notification Area (RNA) update timer periodically based on a RAN (Radio Access Network) times out but the terminal does not successfully recover the RRC connection, or the terminal cannot be solved when in an inactive state and needs to enter an idle state under other failure conditions.
Step 202, reporting the first minimization of drive test information to a network side device.
In this embodiment of the present invention, the terminal in an idle state sends first indication information to the network side device, where the first indication information is used to indicate to the network side device that the terminal in an idle state has the first minimization of drive test information. And then, receiving a first request message sent by the network side equipment, and reporting the first minimization of drive test information to the network side equipment.
For example, the terminal in the idle state may carry indication information (e.g., availability indicator) in an RRC connection setup complete message to inform a network side device (e.g., RAN node) that it has available MDT measurement results. If the network side device desires that the terminal reports the first minimization of drive test information, the UE requests the first minimization of drive test information through a UEInformationRequest message, and the terminal reports the first minimization of drive test information to the network side device through a UEInformationResponse message.
In the embodiment of the invention, when the terminal enters the idle state from the inactive state, the MDT information can be recorded and reported to the network side equipment, so that the network side equipment can know the state transition information in time to better optimize the network.
On the basis of the above embodiment, the terminal may also perform MDT measurement according to the configuration of the network side device, and record the minimization of drive test information. Specifically, before step 201, the method may further include:
and the terminal receives the measurement configuration information sent by the network side equipment, wherein the measurement configuration information comprises state transition record information. Then, the recording of the first minimization of drive test information in step 201 specifically includes: and recording first minimization of drive test information according to the measurement configuration information.
For the terminal in the inactive state, after receiving the measurement configuration information and before entering the idle state, if the terminal also has the minimization of drive test information obtained according to the measurement configuration information, the terminal can also report the minimization of drive test information to the network side equipment, so that the network side equipment can know the information of the network more timely and perform network optimization.
Specifically, the terminal in the inactive state records second minimization of drive test information according to the measurement configuration information, and reports the second minimization of drive test information to the network side device.
When the terminal in the inactive state reports, the terminal can report in the following two ways:
the terminal in the inactive state sends second indication information to the network side device, where the second indication information is used to indicate to the network side device that the terminal in the inactive state has the second minimization of drive test information. Wherein the second indication information is carried in an RRC message.
That is, in this manner, the terminal in the inactive state sends the second indication information to the network side device through the RRC message.
And then, the terminal in the inactive state receives a second request message sent by the network side equipment, and reports the second minimization of drive test information to the network side equipment according to the second request message.
Secondly, the terminal in the inactive state sends third indication information to the network side equipment, wherein the third indication information is used for indicating that the terminal in the inactive state has the second minimization of drive test information to the network side equipment; the third indication information is carried in a MAC Control Element (CE). Then, the terminal in the inactive state receives the reporting indication information sent by the network side device, and reports the second minimization of drive test information to the network side device.
That is, in this manner, the terminal in the inactive state transmits the third indication information to the network side device through the MAC CE.
In this case, the receiving the reporting indication information sent by the network side device includes: and the terminal in the inactive state receives the paging message sent by the network side equipment. And according to the paging message, the terminal enters a connection state. And then, the connected terminal reports the second minimization of drive test information to the network side equipment through an RRC message.
Alternatively, the terminal may not perform the state transition. In this case, the receiving the reporting indication information sent by the network side device includes: the terminal in the inactive state receives reporting indication information sent by the network side device through a Physical Downlink Shared Channel (PDSCH), a Downlink MAC CE, or a Physical Downlink Control Channel (PDCCH). And then, the terminal in the inactive state reports the second minimization of drive test information to the network side device through a Physical Uplink Shared Channel (PUSCH). The reported second minimization of drive test information can be reported by a plurality of uplink data packets.
As shown in fig. 3, an information processing method according to an embodiment of the present invention is applied to a network device, and includes:
step 301, receiving first minimization of drive test information reported by a terminal, wherein the first minimization of drive test information includes information related to state transition of the terminal.
Specifically, in this step, the network side device receives first indication information sent by the terminal in an idle state, where the first indication information is used to indicate that the terminal in the idle state has the first minimization of drive test information. Then, the network side device sends a first request message to the terminal in an idle state, and receives the first minimization of drive test information reported by the terminal in the idle state.
For example, the terminal in the idle state may carry indication information (e.g., availability indicator) in an RRC connection setup complete message to inform a network side device (e.g., RAN node) that it has available MDT measurement results. If the network side device desires that the terminal reports the first minimization of drive test information, the UE requests the first minimization of drive test information through a UEInformationRequest message, and the terminal reports the first minimization of drive test information to the network side device through a UEInformationResponse message.
In the embodiment of the invention, when the terminal enters the idle state from the inactive state, the MDT information can be recorded and reported to the network side equipment, so that the network side equipment can know the state transition information in time to better optimize the network.
On the basis of the above embodiment, the network side device may further send measurement configuration information to the terminal, where the measurement configuration information includes state transition record information to instruct the terminal to perform MDT measurement according to the measurement configuration information.
As described above, before the terminal in the inactive state does not enter the idle state, it may also perform MDT measurement according to the measurement configuration information of the network side device, so as to obtain the minimization of drive test information and report the minimization of drive test information to the network side device. Then, in this embodiment of the present invention, the network side device may further receive second minimization of drive test information reported by the terminal in the inactive state, where the second minimization of drive test information is recorded by the terminal in the inactive state according to the measurement configuration information.
Specifically, the network side device receives second indication information sent by the terminal in the inactive state, where the second indication information is used to indicate that the terminal in the inactive state has the second minimization of drive test information; the second indication information is carried in an RRC message. Then, the network side device sends a second request message to the terminal in the inactive state, and receives the second minimization of drive test information reported by the terminal in the inactive state.
Or, the network side device receives third indication information sent by the terminal in the inactive state, where the third indication information is used to indicate that the terminal in the inactive state has the second minimization of drive test information; the third indication information is carried in the MAC CE. Then, the network side device sends reporting indication information to the terminal in the inactive state, and receives the second minimization of drive test information reported by the terminal.
In this case, the network side device may send a paging message to the terminal in the inactive state, so that the terminal enters the connected state. And then, receiving the second minimization of drive test information reported by the terminal in the connected state.
Or, in this case, the network side device may send reporting indication information to the terminal in the inactive state through a physical downlink shared channel, a downlink MAC CE, or a physical downlink control channel, and then receive the second minimization of drive test information reported by the terminal in the inactive state through a physical uplink shared channel.
As shown in fig. 4, the information processing method according to the embodiment of the present invention includes:
step 401, the RAN node sends measurement configuration information to the terminal.
The measurement configuration information (MDT measurement configuration) is used to instruct the terminal to perform MDT measurement according to the configuration information when entering an idle state from an inactive state, and may include one or more of the following: recording duration, recording interval, area configuration, absolute time, Trace ID (tracking identification), state transition recording information.
The network side device may send the measurement configuration information through an RRC message. The RRC message may be any one of the following messages: logedemeasurementconfiguration, or RRCConnectionRelease, or a newly defined RRC message.
Further, the measurement configuration information may also be equally applicable to a terminal in the ID L E state, even if the terminal makes a state transition, the terminal performs MDT measurement according to the existing measurement configuration information.
Step 402, when the terminal enters an idle state from an inactive state, recording first minimization of drive test information.
Wherein the first MDT information includes information related to a state transition of the terminal. The information related to the state transition of the terminal includes one or more of the following information:
reasons for state transition, timestamps, cell identifiers, base station identifiers, wireless local area network media access control addresses, bluetooth MAC addresses, location information, global positioning system location information.
The reason for the state transition may include any one of: the RRC connection recovery fails, or a CNpaging (core network paging message) is received, or a notification area update (update) timer based on the RAN periodically times out but the terminal does not successfully recover the RRC connection, or in other failure cases, the terminal cannot be solved when in an inactive state and needs to enter an idle state.
It should be noted that the recording of the state transition may be enabled all the time, i.e. recorded as long as the state transition terminal occurs, without configuration. Of course, it is also possible to record the state transition information based on the state transition in step 401, if the indication exists, and if not, no recording is required.
And when the terminal enters an idle state, performing MDT measurement and recording first minimization of drive test information.
Step 403, the idle terminal carries an availability indicator in an RRC connection setup complete (rrcconnectionsetupcomplete) message, and informs the RAN node of an available MDT measurement result.
Step 404, the RAN node requests the terminal to report through a UE information request (UEInformationRequest) message.
Step 405, the terminal reports the information related to the state transition through a UE information response (UEInformationResponse) message.
As shown in fig. 5, between the above steps 401 and 402, the method may further include: and the inactive terminal performs measurement and reporting according to the measurement configuration information. The method comprises the following specific steps:
and the terminal in the non-activated state informs the RAN node of an available MDT measurement result by carrying an availability indicator through the uplink message.
Considering that the terminal in the inactive state has dedicated physical uplink and downlink shared channel resources, the terminal in the inactive state can directly communicate with the network side on the corresponding physical resources even without RRC connection with the RAN node. The uplink message may be an RRC message or a MAC CE.
In this embodiment, there are two possible ways to indicate to the RAN node that MDT measurements are available:
one, the terminal in the inactive state indicates the RAN node to have available MDT measurement results through the MAC CE. In this case, the terminal may report the MDT measurement result to the network in the INACTIVE state without state transition.
Specifically, the following processes can be included:
in step 5031, the terminal in the inactive state carries an availability indicator through the MAC CE to indicate that the RAN node has an available MDT measurement result.
Step 5032, the RAN node indicates the terminal in the inactive state to report through a specific physical downlink shared channel, a downlink MAC CE, or a PDCCH.
Alternatively, the RAN node pages the terminal through the paging message to enter the connected state, and then the terminal in the inactive state reports the MDT measurement result to the network through an RRC message (e.g., UEInformationResponse message) (not shown in the figure).
Step 5033, the terminal in the inactive state reports the MDT measurement result to the network through the specific physical uplink shared channel. As shown, the MDT measurement result may be reported to the network via a plurality of uplink data packets.
Secondly, the terminal in the inactive state indicates that there is available MDT measurement result through RRC message. In this case, the network needs to enter a connected state and report the MDT measurement result to the network through an RRC message.
The RRC message may be an rrcconnectionresummempte message, and the message carries an availability indicator to indicate that the RAN node has an available MDT measurement result.
