Description

Log reporting method, log acquisition method, device and system

technical field

The embodiments of the present invention relate to the technical field of communications, and in particular, to a log reporting method, log acquisition method, device, and system.

Background technique

MDT (Minimization of Drive Tests, Minimization of Drive Tests) can reduce the traditional drive test work performed by operators in the network establishment and subsequent maintenance phases. The MDT may require a terminal executing the MDT to record network conditions in a connected state or an idle (Idle) state, and report the recorded network conditions to the network at an appropriate time.

The MDT in the existing 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) can be divided into two types: Immediate MDT (ImmediateMDT) and Logged MDT (LoggedMDT). ImmediateMDT is an MDT method in which the network side performs MDT configuration on the terminal performing MDT in the RRC (RadioResourceControl, radio resource control protocol) connection state, and the terminal performs MDT measurement and recording in the connection state, and immediately reports the measurement result. LoggedMDT is an MDT method in which the network side performs MDT configuration on the terminal performing MDT in the RRC connection state, the terminal performs MDT measurement and recording in the idle state, and reports the MDT log (MDTlog) when the terminal enters the connected state.

The LoggedMDT process may include: the terminal performs MDT measurement and recording in the idle state. When the terminal enters the connected state, the terminal needs to determine whether the current log belongs to the PLMN (PublicLandMobileNetwork, public land mobile network) is MDTPLMN; wherein, MDTPLMN is the terminal When configuring MDT, the log of the terminal belongs to the PLMN; if the current log belongs to the PLMN of MDTPLMN, the terminal indicates whether the log is valid according to whether there is an MDT log. If there is an MDT log, it indicates to the network that the log is valid; The side indicates that the log is valid; if the current log belongs to a PLMN other than the MDTPLMN, the terminal will not indicate to the network side that the log is valid regardless of whether the terminal has an MDT log.

PLMN changes may occur when a terminal undergoes cell selection or reselection. For example: when the terminal moves from the cell of PLMN1 to the cell of PLMN2, the home PLMN of the log of the terminal will change from PLMN1 to PLMN2. However, when the terminal has just moved from the cell of PLMN1 to the cell of PLMN2, the terminal may not have performed the Tracking Area Update (TAU) process, and the terminal has not yet performed the PLMN re-registration process, so the terminal maintains the current Log attribution to PLMN has not changed. At this time, the terminal judges that the current log belongs to MDTPLMN, so the terminal indicates to the control base station of the target cell that the MDTlog is valid, and reports the MDTlog to the network side when the control base station of the target cell asks for the MDTlog. As a result, the terminal reports the MDT log corresponding to the PLMN1 to the cell of the PLMN2, thus causing an erroneous report of the MDT log.

Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flow chart of Embodiment 1 of the log reporting method of the present invention. As shown in FIG. 1 , the method includes the following contents.

101. A terminal acquires a PLMN list of a target cell.

Wherein, the above-mentioned target cell is the target cell when the terminal is handed over, or the above-mentioned target cell is the cell where the terminal resides after cell reselection occurs, for example: the terminal will select the signal The cell with the best quality (that is, the target cell) resides.

In different application scenarios, the terminal can acquire the PLMN list of the above-mentioned target cell by receiving the RRC connection establishment message, RRC connection reconfiguration message or RRC connection re-establishment message carrying the PLMN list of the target cell; The broadcast channel of the target cell is used to obtain the PLMN list of the target cell.

After obtaining the PLMN list of the target cell, the terminal may further obtain the PLMN that the terminal belongs to in the log of the target cell.

The logs in this embodiment may be MDT logs, RLF logs or ANR (Automatic NeighbourRelation, automatic neighbor relationship) logs. Correspondingly, the PLMN to which the logs belong may be the following two types.

Case 1: When the log is an MDT log, the PLMN attributable to the log is MDTPLMN, which can be the PPLMN (primary PLMN) of the terminal when the MDT log is configured for the terminal; when the log is an RLF log, the PLMN attributable to the log is RLFPLMN, The RLFPLMN may be the PPLMN of the terminal when RLF occurs in the terminal; when the log is an ANR log, the PLMN to which the log belongs is ANRPLMN, and the ANRPLMN may be the PPLMN of the terminal when the ANR log is configured for the terminal.

The second case: when the log is an MDT log, the PLMN attributable to the log is MDTPLMN, and the MDTPLMN can be the RPLMN (registered PLMN) of the terminal when the MDT log is configured for the terminal; when the log is an RLF log, the PLMN attributable to the log is RLFPLMN , the RLFPLMN may be the RPLMN of the terminal when RLF occurs in the terminal; when the log is an ANR log, the PLMN to which the log belongs is ANRPLMN, and the ANRPLMN may be the RPLMN of the terminal when the ANR log is configured for the terminal.

102. The terminal judges, according to the PLMN list of the target cell, whether the log home PLMN of the terminal in the target cell is the same as the log home PLMN of the terminal in the source cell.

Specifically, after the terminal obtains the PLMN to which the log of the terminal in the target cell belongs, it can determine whether the PLMN to which the log of the terminal in the target cell belongs is the same as the PLMN to which the log of the terminal in the source cell belongs; Whether the attribution PLMN will change, that is, whether the log attribution PLMN will change after a preset time or a preset process.

Wherein, the preset time may adopt a preset default value or a network configuration manner, for example, setting the preset time as T. After receiving the PLMN list of the target cell, the terminal judges that the PLMN that the log belongs to will not change in the subsequent time T, then it determines that the PLMN that the log belongs to will not change.

The preset process may be a preset default process or a network configuration method, for example, the preset process is set to be a TAU update completion message. When the terminal receives the PLMN list of the target cell and judges that the home PLMN will not change after the subsequent TAU update complete message, it determines that the home PLMN will not change.

The above-mentioned terminal judges whether the log belonging PLMN of the terminal in the target cell is the same as the log belonging PLMN of the terminal in the source cell according to the PLMN list of the target cell, that is, the process for the terminal to determine whether the log belonging PLMN will be changed may specifically include:

1. The log belongs to the PLMN in the first case above:

If the log attributable PLMN of the terminal in the source cell is PLMN1, and the first PLMN in the PLMN list of the target cell is PLMN1, after the terminal enters the target cell, the log attributable PLMN will not change, and it is still PLMN1, so it can be judged The log home PLMN of the terminal in the target cell is the same as the log home PLMN of the terminal in the source cell, that is, the log home PLMN will not change after the preset time or preset process;

If the log attributable PLMN of the terminal in the source cell is PLMN1, and the first PLMN in the PLMN list of the target cell is not PLMN1, after the terminal enters the target cell, the log attributable PLMN will be changed to the first in the PLMN list of the target cell PLMN, thus it can be judged that the log home PLMN of the terminal in the target cell is different from the log home PLMN of the terminal in the source cell, that is, the log home PLMN changes after a preset time or a preset process.

2. The log belongs to the PLMN in the second case above:

If the log attributable PLMN of the terminal in the source cell is PLMN1, and the PLMN list of the target cell only includes PLMN1, after the terminal enters the target cell, the log attributable PLMN will not change, and it is still PLMN1, so it can be judged that the terminal is in the target cell. The log attributable PLMN of the target cell is the same as the log attributable PLMN of the terminal in the source cell, that is, the log attributable PLMN will not change after the preset time or preset process;

If the log attributable PLMN of the terminal in the source cell is PLMN1, and the PLMN list of the target cell does not include PLMN1, after the terminal enters the target cell, the log attributable PLMN will be changed to a PLMN in the PLMN list. The log home PLMN of the terminal in the target cell is different from the log home PLMN of the terminal in the source cell, that is, the log home PLMN changes after a preset time or a preset process;

If the PLMN of the terminal's log in the source cell belongs to PLMN1, and the PLMN list of the target cell includes at least PLMN1 and PLMN2, it is necessary to judge the terminal's access to the target according to the priority of each PLMN in the PLMN list of the target cell or according to the user's manual selection. After the cell, whether the log belongs to PLMN is still PLMN1, and if so, it is determined that the log belongs to the PLMN of the terminal in the target cell and the log belongs to the PLMN of the terminal in the source cell, that is, the log belongs to the PLMN after the preset time or preset process. Will change, if not, then it is judged that the terminal's log attributable PLMN in the target cell is different from the log attributable PLMN of the terminal in the source cell, that is, the log attributable PLMN will change after a preset time or a preset process.

103. If the home PLMN of the log of the terminal in the target cell is the same as the home PLMN of the log of the terminal in the source cell, the terminal sends the log to the control base station of the target cell.

Wherein, the controlling base station in this embodiment may include an evolved base station (eNB) in an LTE network, or may include a radio network controller (Radio Network Controller, RNC for short) and a base station (NB) in a UTRAN network.

If the above-mentioned terminal determines that the log attributable PLMN of the terminal in the target cell is the same as the log attributable PLMN of the terminal in the source cell, that is, the log attributable PLMN does not change after the preset time or preset process, then the terminal can report the log to the target cell . The method for the terminal to report the log to the target cell may specifically include the following two methods: 1. The terminal determines that the PLMN of the log of the terminal in the target cell is the same as the PLMN of the log of the terminal in the source cell, that is, the log belongs to the PLMN at the preset time or After the preset process is not changed, the terminal sends an indication message that the log is valid to the control base station of the target cell, and then the control base station of the target cell sends a log request to the terminal according to the indication message, and the terminal sends a log request to the control base station of the target cell according to the log request. Log; 2. The terminal first sends identification information indicating that the terminal has a log to the control base station of the target cell, and then the terminal judges that the PLMN of the log of the terminal in the target cell is the same as the PLMN of the log of the terminal in the source cell, that is, the log belongs to The PLMN does not change after the preset time or preset process. The control base station of the target cell knows that the terminal has a log according to the above identification information indicating that the terminal has a log, and sends a log request for obtaining the log to the terminal. When the terminal receives the target cell When the control base station of the target cell sends a log request according to the above identification information, the terminal sends the log to the control base station of the target cell.

If the above-mentioned terminal judges that the log attributable PLMN of the terminal in the target cell is different from the log attributable PLMN of the terminal in the source cell, that is, the log attributable PLMN changes after the preset time or the preset process, the terminal will not report to the target cell. The base station reporting the log may specifically include: the terminal sends indication information for indicating that the log is invalid to the control base station of the target cell, or the terminal sends an empty report message that does not include the log to the control base station of the target cell. In the specific implementation process, when the terminal requests to report the log based on the log of the control base station of the target cell, the manner in which the terminal does not report the log to the target cell may specifically include: 1. The terminal determines that the log of the terminal in the target cell belongs to the PLMN and If the log attributable PLMN of the terminal in the source cell is different, that is, the log attributable PLMN changes after a preset time or a preset process, the terminal will not send an indication message that the log is valid to the control base station of the target cell, or send a valid log message to the control base station of the target cell. Send an indication message that the log is invalid, so that the control base station of the target cell will not send a log request to the terminal to obtain the log, and the terminal will not report the log to the control base station of the target cell; 2. The terminal first sends an indication to the control base station of the target cell The terminal has log identification information, and then the terminal determines that the log attributable PLMN of the terminal in the target cell is different from the log attributable PLMN of the terminal in the source cell, that is, the log attributable PLMN will change after a preset time or a preset process, The controlling base station of the target cell knows that the terminal has a log according to the above identification information indicating that the terminal has a log, and sends a log request for obtaining the log to the terminal. When the terminal receives the log request sent by the controlling base station of the target cell according to the above identification information, The terminal sends an empty report without logs to the network side.

In the embodiment of the present invention, when the terminal judges that the log attributable PLMN of the terminal in the target cell is the same as the log attributable PLMN of the terminal in the source cell, that is, when the log attributable PLMN will not change after the preset time or preset process, the terminal will report to the The control base station of the target cell sends the log, thereby preventing the terminal from reporting the log to the target cell when the PLMN to which the log belongs is about to change, thereby avoiding erroneous reporting of the log.

The target cell reports logs, thereby avoiding false reporting of logs.

FIG. 3 is a flow chart of Embodiment 1 of the log processing method of the present invention. As shown in FIG. 3 , this embodiment mainly introduces the implementation process in the terminal. The method includes the following contents.

301. The access (Access Stratum, AS for short) layer of the terminal receives the PLMN list of the target cell, and sends the PLMN list to the non-access Stratum (Non-Access Stratum, NAS for short) layer of the terminal.

The AS layer of the terminal receives the PLMN list of the target cell; then the AS layer of the terminal sends the received PLMN list to the NAS layer of the terminal.

This embodiment is based on the embodiments shown in FIG. 1 and FIG. 2 . This embodiment is described by taking an LTE network as an example, and the application of this embodiment is not limited to the LTE network. Specifically, in the LTE system, the above-mentioned PLMN list may be included in an RRC Connection Setup (RRCConnectionSetup) message, an RRC Connection Reconfiguration (RRCConnectionReconfiguration) message, or an RRC Connection Reestablishment (RRCConnectionReestablishment) message; wherein, the RRC Connection Setup message is an RRC connection The message sent by the control base station of the target cell to the terminal in the establishment scenario, the RRC connection reconfiguration message is the message sent by the control base station of the source cell to the terminal in the handover scenario, and the RRC connection reestablishment message is sent to the terminal by the control base station of the target cell in the RRC reconstruction scenario. Terminal messages. If this embodiment is applied in the UTRAN network, the PLMN list is added to the messages corresponding to the above messages. For example, in the UTRAN network, the handover process corresponds to the relocation process.

It should be noted that when the PLMN list of the target cell is sent to the terminal through the RRC connection reconfiguration message, the control base station of the target cell sends the PLMN list of the target cell to the control base station of the source cell first, and then the source cell The controlling base station sends the PLMN list of the target cell to the terminal through an RRC connection reconfiguration message.

In another embodiment, the terminal can also obtain the PLMN list of the target cell by reading the broadcast channel of the target cell; for example: the AS layer of the terminal obtains the PLMN list of the target cell by reading the broadcast channel of the target cell, and then Send the acquired PLMN list of the target cell to the NAS layer of the terminal.

302. The NAS layer of the terminal judges whether the log attributable PLMN of the terminal in the target cell is the same as the PLMN attributable to the log of the terminal in the source cell, and sends the judgment result to the access layer of the terminal.

Optionally, the NAS layer of the terminal can obtain the PLMN that the log of the terminal in the target cell belongs to according to the PLMN list of the target cell, and then perform the judgment process. For the specific process of obtaining the PLMN that the log of the terminal in the target cell belongs to and the judgment process, please refer to Figure 1 Description in 101 and 102 in the illustrated embodiment.

The AS layer of the terminal receives the log request sent by the control base station of the target cell for acquiring logs, and sends the log to the control base station of the target cell according to the log request. In a specific implementation process, the control base station of the target cell sends a log request for acquiring logs to the terminal according to the received indication information indicating that the logs are valid.

Optionally, in another embodiment, in 303, if it is determined that the PLMN of the terminal's NAS layer log in the target cell is the same as the terminal's log attributable PLMN in the source cell, the terminal can actively report to the control base station of the target cell To send logs, at this time, the above-mentioned 304-305 may not be executed.

Optionally, in another implementation manner, before 301 in this embodiment may also include:

300. The terminal sends identification information indicating that the terminal has a log to the control base station of the target cell, so that the control base station of the target cell sends the PLMN list of the target cell to the terminal according to the identification information.

The terminal informs the control base station of the target cell whether the terminal has a log, so that the control base station of the target cell only sends the PLMN list of the target cell to the terminal with the log.

Specifically, in the RRC connection establishment scenario, the terminal may carry identification information indicating that the terminal has a log in the RRC connection request (RRCConnectionRequest) message; in the reconstruction scenario, the terminal may carry in the RRC connection reestablishment request (RRCConnectionReestablishmentRequest) message The identification information used to indicate that the terminal has a log; in the handover scenario, after the terminal notifies the control base station of the source cell of the information that the terminal has a log, the control base station of the source cell can pass the network node interface (X2 or S1) in the handover request Send the identification information that the terminal has the log to the controlling base station of the target cell.

In the embodiment of the present invention, the terminal will send the log to the target cell only when it determines that the PLMN of the terminal's log in the target cell is the same as that of the terminal's log in the source cell. The target cell reports the log, so as to avoid the wrong report of the log; and, the terminal can also report the identifier of the terminal having the log to the target cell first, so that the target cell only sends the PLMN of the target cell to the terminal with the log, thereby reducing the need for other terminal impact.

In the embodiment shown in FIG. 3 , the terminal may send indication information indicating that the log is valid to the control base station of the target cell when it is determined that the PLMN of the log of the terminal in the target cell is the same as the PLMN of the log of the terminal in the source cell, and then The terminal reports the log to the target cell according to the log request sent by the control base station of the target cell. In another embodiment, before judging whether the log home PLMN of the terminal in the target cell and the log home PLMN of the terminal in the source cell are the same, the terminal first sends a message indicating that the terminal has a log to the control base station of the target cell. Identification information. At this time, when the control base station of the target cell requests the terminal to obtain logs based on the identification information, the terminal can determine whether the PLMN of the terminal’s log in the target cell is the same as the PLMN of the terminal’s log in the source cell. Whether to report the log to the target cell, this situation will be described in detail below through the embodiment shown in FIG. 4 .

FIG. 4 is a flow chart of Embodiment 2 of the log processing method of the present invention. As shown in FIG. 4 , the method includes the following contents.

401. The terminal generates RLF in a cell whose PPLMN (or RPLMN) is PLMN1 (ie, the source cell), and at this time, the terminal stores PLMN1 as RLF PLMN.

In this embodiment, the log is described as an RLF log as an example, but it is not limited thereto.

402. The terminal is handed over from the cell of PLMN1 to the target cell, and the control base station of the source cell carries an identifier of a valid RLF log in the handover request to the control base station of the target cell.

403. The control base station of the source cell receives the PLMN list of the target cell sent by the control base station of the target cell, and then sends the PLMN list of the target cell to the terminal in an RRC connection reconfiguration message.

404. The AS layer of the terminal sends the PLMN list of the target cell to the NAS layer of the terminal.

405. The NAS layer of the terminal sends the judgment result of whether the RLFPLMN will be changed to the AS layer of the terminal, that is, the NAS layer of the terminal sends the judgment result of whether the log of the terminal in the target cell belongs to the PLMN and the log of the terminal in the source cell belongs to the same PLMN. To the AS layer of the terminal.

406. The AS layer of the terminal decides whether to report the log according to the judgment result sent by the NAS layer. If the RLF PLMN will not change, the AS layer will report the RLF log to the target cell when the control base station of the target cell asks for the RLF log; if the RLF PLMN will change, the AS layer will not report the RLF log to the target cell when the control base station of the target cell asks for the RLF log The cell reports the real RLF log, but sends an empty report message that does not include the log to the target cell.

In the embodiment of the present invention, when the terminal determines that the PLMN of the terminal's log in the target cell is the same as the PLMN of the terminal's log in the source cell, it will report the log to the target cell according to the log request sent by the target cell.
