Description

Information processing method, network side equipment and terminal
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 modes, minimization of drive tests (Minimization Drive Test, MDT) can be divided into two types:
first, record MDT (logged MDT): an IDLE state (IDLE) User Equipment (UE) makes MDT measurements according to a logedmeasurementconfiguration. The UE records the collected data for a period of time prior to the reporting of the data. This type of application is typically used when the UE is in an idle state in which no connection is established between the UE and the radio access network (Radio Access Network, RAN) node.
Second, instant MDT (immediate MDT): the CONNECTED UE makes MDT measurements according to RRCConnectionReconfiguration. Such UEs would report the collected data to the network side on-the-fly. This type of application is typically used 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 technique, the UE state has an intermediate state, i.e., INACTIVE state (INACTIVE), in addition to the two states, IDLE and CONNECTED. In the INACTIVE state, the radio resource control protocol (Radio Resource Control, RRC) connection between the UE and the RAN node is released. When the RRC connection needs to be restored, a connection is established by sending an RRCConnectionResumeRequest carrying resumeconsistency.
The inactive UE may autonomously change to the IDLE state during the MDT measurement. However, there is no solution in the prior art about how MDT measurement is performed by the inactive state UE at the time of state transition.

As shown in fig. 1, the wireless communication system may include: network-side device 11 and terminal 12. In practical application, the connection between the devices may be wireless connection, and for convenience and intuitionistic representation of the connection relationship between the devices, a solid line is used for illustration in fig. 1.
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 device such as a next generation base station (next generation node base station, gNB) or a transmission and reception point (transmission and reception point, TRP) in a 5G (Fifth generation mobile communication technology) system.
The terminal may be a cell phone, tablet computer, notebook computer, ultra mobile personal computer (Ultra-Mobile Personal Computer, UMPC), netbook, personal digital assistant (Personal Digital Assistant, PDA), or the like.
As shown in fig. 2, the information processing method of the embodiment of the present invention is applied to a terminal, and includes:
step 201, recording first minimization of drive test information, wherein the first minimization of drive test information comprises information related to state transition of the terminal.
Specifically, in the embodiment of the present invention, when a terminal enters an idle state from an 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.
Wherein the information related to the state transition of the terminal includes one or more of the following information: the reasons for the state transition, time stamps, cell Identification (ID), base station Identification, wireless local area network (Wireless Local Area Networks, WLAN) medium access control (Media Access Control, MAC) address, bluetooth MAC address, location information, global positioning system (Global Positioning System, GPS) location information.
The reasons for the state transition may include any one of the following: the RRC connection recovery fails, or a CN paging message is received, or a notification area (RAN-based Notification Area, RNA) update timer based on RAN (Radio Access Network ) periodically times out but the terminal does not successfully recover the RRC connection, or in other failure situations, the terminal cannot be resolved while in an inactive state and needs to enter an idle state.
Step 202, reporting the first minimization of drive test information to a network side device.
In the embodiment of the invention, the terminal in the idle state sends first indication information to the network side equipment, wherein the first indication information is used for indicating to the network side equipment that the terminal in the 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 idle state may carry indication information (e.g., availability indicator) in an rrcconnectionsetup complete message to inform the network side device (e.g., RAN node) that it has MDT measurement results available. If the network side device wants the terminal to report the first minimization of drive test information, the terminal reports the first minimization of drive test information to the network side device through a UEInformationRequest (UE information request) message request and a UEInformationResponse (UE information response) message.
In the embodiment of the invention, when the terminal enters the idle state from the inactive state, 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 perform network optimization.
Based on 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 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 is specifically: and recording first minimization drive test information according to the measurement configuration information.
For the terminal in the inactive state, after the measurement configuration information is received and before the terminal enters the idle state, if the terminal also has the minimization of drive test information acquired 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 equipment.
When the terminal in the inactive state reports, the terminal can report in the following two modes:
1. and the terminal in the inactive state sends second indication information to the network side equipment, wherein the second indication information is used for indicating to the network side equipment 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 transmits 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.
2. The terminal in the inactive state sends third indication information to the network side equipment, wherein the third indication information is used for indicating to the network side equipment that the terminal in the inactive state has the second minimization of drive test information; the third indication information is carried in a MAC Control Element (CE). And then, the terminal in the inactive state receives the reporting instruction information sent by the network side equipment and reports the second minimization of drive test information to the network side equipment.
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 report instruction 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 terminal in the connection state reports the second MDT information to the network side equipment through an RRC message.
Alternatively, the terminal may not make a state transition. In this case, the receiving the report instruction information sent by the network side device includes: and the terminal in the inactive state receives the reporting indication information sent by the network side equipment through a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a downlink MAC CE or a physical downlink control channel (Physical Downlink Control Channel, PDCCH). And then, the terminal in the inactive state reports the second MDT information to the network side equipment through a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). The second minimization of drive tests information may be reported via a plurality of uplink data packets.
As shown in fig. 3, the information processing method of the embodiment of the present invention is applied to a network side device, and includes:
step 301, receiving first minimization of drive test information reported by a terminal, wherein the first minimization of drive test information comprises 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 the 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. And then, the network side equipment sends a first request message to the terminal in the idle state and receives the first minimization of drive test information reported by the terminal in the idle state.
For example, the terminal in idle state may carry indication information (e.g., availability indicator) in an rrcconnectionsetup complete message to inform the network side device (e.g., RAN node) that it has MDT measurement results available. If the network side device wants the terminal to report the first minimization of drive test information, the terminal reports the first minimization of drive test information to the network side device through a UEInformationRequest (UE information request) message request and a UEInformationResponse (UE information response) message.
In the embodiment of the invention, when the terminal enters the idle state from the inactive state, 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 perform network optimization.
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, so as to instruct the terminal to perform MDT measurement according to the measurement configuration information.
Before the terminal in the inactive state does not enter the idle state, as described above, it may also perform MDT measurement according to 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. 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 an 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. And then, the network side equipment sends a second request message to the terminal in the inactive state and receives the second MDT 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. And then, the network side equipment sends reporting indication information to the terminal in an 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 MDT information reported by the terminal in the connection 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.
Wherein the measurement configuration information (MDT measurement configuration) is used for indicating the terminal to perform MDT measurement according to the configuration information when the terminal enters the idle state from the inactive state, and may include one or more of the following: recording duration, recording interval, region configuration, absolute time, trace ID (Trace identification), state transition record information.
The network side device may transmit the measurement configuration information through an RRC message. The RRC message may be any one of the following messages: the logedmeasurementconfiguration, or RRCConnectionRelease, or a newly defined RRC message.
Further, the measurement configuration information may also be equally applicable to the IDLE state terminal. Even if the terminal makes a state transition, the terminal still 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 minimization of drive test information comprises 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:
the reasons for the state transition, time stamp, cell identity, base station identity, wireless local area network medium access control address, bluetooth MAC address, location information, global positioning system location information.
The reasons for the state transition may include any one of the following: the RRC connection recovery fails, or a CN paging message is received, or a periodic RAN-based notification area update timer times out but the terminal fails to recover the RRC connection, or in other failure cases, the terminal cannot resolve when in an inactive state and needs to enter an idle state.
It should be noted that, the record of the state transition may be enabled all the time, that is, the record is recorded as long as the state transition terminal occurs, and no configuration is required. Of course, the state transition information may also be recorded based on the state transition information in step 401, if the indication is present, and if not, no recording is required.
And when the terminal enters an idle state, MDT measurement is carried out, and first minimization of drive test information is recorded.
In step 403, the idle state terminal carries availability indicator (available indication) in an RRC connection setup complete (rrcconnectionstatum) message informing the RAN node that there is 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 (UE information response) message.
As shown in fig. 5, between the above steps 401 and 402, the method may further include: and the terminal in the inactive state performs measurement and reporting according to the measurement configuration information. The method comprises the following steps:
the terminal in the inactive state informs the RAN node of the available MDT measurement result through the uplink message bearer availability indicator.
Considering that the terminal in the inactive state has a dedicated physical uplink and downlink shared channel resource, the terminal in the inactive state can directly communicate with the network side on the corresponding physical resource even if there is no 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 that the RAN node has available MDT measurements:
and one, the terminal in the inactive state indicates that the RAN node has 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 method can comprise the following steps:
in step 5031, the inactive terminal carries availability indicator via the MAC CE to indicate that the RAN node has available MDT measurements.
In 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 a paging message, makes it enter a connection state, and then the terminal in an inactive state reports the MDT measurement result to a network (not shown in the figure) through an RRC message (e.g., ueinformation response message).
