Description

The present invention claims to be filed on September 28, 2010, the Chinese Patent Office, the application number is 201010294844.3, the Chinese patent application entitled "A MDT Measurement Information Feedback Method and Apparatus" Priority is hereby incorporated by reference in its entirety. Technical field

The present invention relates to the field of communications technologies, and in particular, to a feedback method and device for MDT measurement information. Background technique

In the existing technical solutions, the MDT (Minimization Drive Test) measurement is divided into Immediate MDT (Immediate Minimized Drive Test Mechanism, IMD MDT) and Logged MDT (Log-type Minimized Drive Test Mechanism, LOG MDT) Two types:

Immediate MDT, the MDT measurement and reporting performed by the terminal device in the connected state, multiplexing the form of RRM (Radio Resource Management) measurement. Once the reporting condition is met, the terminal device immediately goes to the eNB (evolved Node B, evolved base station). /RNC (Radio Network Controller) reports the measurement results.

The Logged MDT, the MDT measurement performed by the terminal device in the idle state, is reported in the subsequent connection state. Once the configured trigger conditions are met, the measurement results are obtained and stored (Log) and reported to the eNB/RNC at a suitable time.

The MDT's Log configuration is sent by the network to the terminal device in the connected state. It is not extended based on the existing RRM measurement, but a new configuration method is defined.

Terminal device side: When the terminal device releases the RRC (Radio Resource Control) connection, the received Log configuration will not be released at the same time, but will continue to keep and enable the idle log measurement and measurement result collection.

Network side: For Logged MDT, the network does not retain the MDT context (up and down The information, the MDT context is not transmitted on the network side. When the RRC connection is released, the MDT context saved on the network side is also released.

The existing MDT measurements determine the following 7 UE measurements:

1. Periodical downlink pilot measurements 2. Serving Cell becomes worse than threshold (the service cell becomes worse than the set threshold)

3, Transmit power headroom becomes less than threshold ( PHR is worse than the set threshold)

4, Random access failure (random access failure)

5, Paging Channel Failure (paging channel failure)

6. Broadcast Channel failure (Broadcast channel failure)

7, Radio link failure report (Radio link failure 4 report)

In addition to the above seven measurement quantities, in the subsequent standard process, it is not excluded to add other measurement quantities, such as QoS (Quality of Service) related measurement of the terminal device. If some of these measurements are used in the connected MDT, when the network sends these measurement configurations, the terminal will monitor the connected state. When an event is triggered, the RRM measurement station is still multiplexed. The reported message is used for reporting to the network side.

In the case of Logged MDT, when the terminal device stores valid MDT Log information, if the terminal device enters the connected state or moves to the new cell, the terminal device will

The Log available message is reported to the network through RRC signaling.

Taking the LTE (Long Term Evolution) system as an example, the flow chart of the RRC connection establishment process is shown in Figure 1. After the RRC connection is successfully established, the terminal device will send the RRC Connection Setup Complete to the network. The message is completed. At this time, the message carries the indication information of the available MDT Log information (that is, the foregoing Log available indication message). After receiving the indication, the network may subsequently request the terminal device to save the MDT. The Log information is reported.

Similarly, in the cell handover and cell reestablishment process of the LTE system, the terminal device sends a Log available indication message to the base station of the handover target cell/reconstructed cell, It is notified whether the new cell stores the available MDT Log information in the terminal device.

In the UMTS (Universal Mobile Telecommunications System) system, if an SRNS (Serving Radio Network Subsystem) relocation process occurs, the terminal device also sends a Log available indication message to the target. Community.

Currently, in the standard discussion, the position information is provided that the terminal device provides the best location information for each time the Log (IDLE state) or the trigger report (connected state) is provided. If the accurate location information cannot be provided, the terminal device will provide an RF fingerprint, which is in the form of a currently measurable neighbor cell signal quality that satisfies certain conditions, and the current neighbor cell signal reporting is based on a threshold (threshold). There is still no conclusion on the maximum number limit.

Since the provision of the accurate location information is best effort, and it is highly probable that the acquisition time of the accurate information is not the same as the Log time or the trigger reporting time of the MDT, there is also a problem of how to associate the accurate location information with the measurement result. .

In the standard conference discussion, the provision of accurate location information by the company is necessary for the operator to optimize the network, and its importance even exceeds the periodic pilot measurement, because the precise location information of the latter provides the best equipment requirements for the terminal equipment. The introduction of the MDT event measurement based on the accurate location information triggering means that when the terminal device has a new accurate location information update result, the terminal device in the connected state reports the wireless signal quality measured at this time together with the accurate location information to the network. The terminal device in the IDLE state only logs the measured wireless signal quality along with the precise location information, and then reports to the connected state in the polling of the network.

In carrying out the process of the present invention, the inventors have found that the prior art has at least the following problems:

The introduction of MDT event measurement based on precise location information triggering can help operators to perform more precise network optimization. However, if the precise positioning frequency of the terminal device is very high (such as car driving navigation), then each time the new location information is acquired, the Log or measurement report of the MDT will be triggered, which will inevitably result in excessive device memory (storage space) consumption. And airing the overhead. A prohibit timer is mentioned in the standard discussion. The mechanism of the device, that is, before the timer (timer) times out, the terminal device does not trigger the Log or the measurement reporting behavior. However, the timer alone cannot solve the needs of operators for accurate location information. Because the mechanism of the timer does not comprehensively consider the moving speed of the terminal device, there is a possibility that the positions between the two Logs or the measurement are very close. There is no corresponding solution in this prior art for this problem. Summary of the invention

detailed description

In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, the manual participation of network planning and operation and maintenance is reduced, and the network automatically optimizes parameters according to statistics, thereby reducing network construction and operation costs. In order to reduce the operation and maintenance cost of the network, it is hoped that the network configuration UE reporting method can be adopted to reduce the manual road test work, that is, the minimization of the road test (MDT) scheme. On the other hand, it is also desirable to be able to obtain wireless measurement information of an area that cannot be reached by ordinary road test.

The purpose of MDT collection is to optimize network operations. If the terminal device can only provide wireless signal measurement results and cannot provide location information or provide accurate location information, it is difficult for operators to optimize the specific deployment location of the network.

The embodiment of the present invention provides a feedback method for MDT measurement information, and performs MDT measurement when the position requirement is met, and reports the measurement result and the corresponding position information according to the corresponding strategy, thereby solving the problem of how to provide accurate when collecting MDT. Location information issue.

As shown in FIG. 2, it is a schematic flowchart of a method for feeding back MDT measurement information according to an embodiment of the present invention, where the method specifically includes the following steps:

Step S201: The network side device sends, to the terminal device, an MDT configuration message that includes recording requirement information of the location information on the network side.

In the specific application scenario, before this step, it also includes:

The network side device receives the operation management and maintenance message sent by the OAM system including the current network side to the location requirement information of the location information.

In an actual application, the network side's location requirement information for the location information may be specifically the minimum location interval information, or other information that can reflect the location information recording accuracy requirement of the network side, such as interval information, etc., such changes are not Affecting the protection of the present invention Wai.

Step S202: The terminal device receives an MDT configuration message that is sent by the network side device and includes the network side to the location requirement information.

In an actual application, if the MDT measurement type of the terminal device application is an IMD MDT, the MDT configuration message is specifically an RRC Connect Reconfiguration (RRC) connection message;

If the MDT measurement type of the terminal device application is LOG MDT, the MDT configuration message, specifically Logged Measurement Configuration, step S203, the terminal device determines whether the current location meets the record requirement information of the network side for the location information. Requirements.

As described in step S201, if the recording requirement information of the location information on the network side may be specifically the minimum location interval information, the processing of this step is correspondingly changed between the location where the terminal device determines the current location and the location where the measurement information was last generated. Whether the interval is greater than the minimum position interval information.

If the result of the determination is yes, step S204 is performed;

If the result of the determination is no, step S206 is performed.

The specific processing of this step is as follows:

The terminal device obtains current location information through a GNSS (Global Navigation Satellite System) or an LCS (Location Service) server;

The terminal device determines, according to the current location information, whether the current location meets the requirements of the network side for the record requirement information of the location information.

Step S204: The terminal device generates current measurement information, and measures location information corresponding to the information and the measurement information to the network side device according to the corresponding rule.

The current measurement information generation process is as follows:

If the MDT measurement type of the terminal device is an IMD MDT, and the terminal device is currently in a connected state, the terminal device generates current measurement information, and reports the location information corresponding to the measurement information and the measurement information to the network side device; If the MDT measurement type of the terminal device is LOG MDT, and the terminal device is currently in an idle state, the terminal device generates log information including current measurement information and location information corresponding to the measurement information, and switches the terminal device to the connection state. Then, all the log information including the measurement information and the location information corresponding to the measurement information generated during the idle state is reported to the network side device.

Step S205: The network side device receives the measurement information reported by the terminal device and the location information corresponding to the measurement information.

As described above, in this step, the measurement information received by the network side device is generated when the current location of the terminal device reaches the updated network side request for the location requirement information of the location information, if the minimum location interval information is For example, it may be generated when the interval between the current location of the terminal device and the location where the measurement information was last generated is greater than the minimum location interval information.

Step S206: The terminal device gives up generating current measurement information.

It should be further noted that after the foregoing process is completed, the technical solution proposed by the embodiment of the present invention may further include an update configuration of the corresponding network side location information, 3⁄4 recording demand information, and the like (eg, minimum location interval information). The process is similar to the step S201. If the network side device receives the message that the OAM system sends the record requirement information including the updated network side location information, the network side device sends the updated network side location to the terminal device. Recording the MDT configuration message of the information request information, and receiving the measurement information corresponding to the measurement information and the measurement information reported by the terminal device according to the flow similar to the steps S203 to S206, wherein the measurement information in the process is current in the terminal device The location is generated when the updated network side requests the location requirement information for the location information.

By applying the technical solution proposed by the embodiment of the present invention, the network side device notifies the terminal device of the need for the accurate location information record, so that the terminal device performs the MDT measurement when the current location reaches the corresponding accurate location information record requirement. And the reporting of the measurement result and the location information, thereby solving the problem of excessive overhead caused by the terminal device frequently triggering the location information record, and effectively saving the air interface resource of the system. The technical solutions proposed in the embodiments of the present invention are described in detail below with reference to specific application scenarios.

In practical applications, the accurate location information in the MDT solution is provided for the operator to perform network optimization more accurately. In different periods, the operator may have different requirements for the precise location information of the MDT. The requirement may be reflected in the MDT measurement configuration. in.

In practical applications, other types of recording requirement information of the location information on the network side are also applicable to The scope of protection of the embodiments of the present invention.

In this case, on the terminal device side, the next log record is triggered only when the distance between the current update location and the last log record (log) or the measured report location is greater than the configured minimum location interval information. ) or measurement report.

The measurement configuration in the above technical solution is also applicable to LOG MDT measurement and IMD MDT measurement.

In the following, a specific embodiment application scenario is given for the above two types of MDT measurement types, so as to explain the technical solution.

Application scenario 1, LOG MDT measurement

FIG. 3 is a schematic flowchart of a method for feeding back MDT measurement information in a LOG MDT measurement scenario according to an embodiment of the present disclosure, where the method specifically includes the following steps:

Step S301: The terminal device receives the MDT measurement configuration message sent by the base station in the connected state.

In practical applications, the MDT measurement configuration message is a Logged Measurement Configuration message.

In the above process, the MDT measurement configuration message carries a requirement for providing accurate location information to the terminal device, that is, minimum location interval information, for example, 10 m.

Step S302: The terminal device starts the log after leaving the connected state to enter the IDLE state. Logs triggered by location information events and other (if configured) periodic pilot measurements The log of the quantity is independent of each other.

Step S303: The terminal device determines whether the interval between the current location and the location of the last log reaches the minimum location interval information.

If it is not reached, that is, the accurate location information update obtained by the terminal device through GNSS or the like and the position information interval under the last log are less than 10 m, step S304 is performed.

If it is reached, that is, the accurate location information update obtained by the terminal device through GNSS or the like and the location information interval under the last log are equal to or greater than 10 m, step S305 is performed.

Step S304: The terminal device does not trigger the logging behavior.

Step S305: The terminal device performs log at the current location.

The wireless signal quality measurement result (for example, the resident downlink downlink pilot information) is recorded at the exact location of the Log, and does not include the RF fingerprint information.

Step S306: After leaving the IDLE state and entering the connected state, the terminal device reports the recorded log information to the base station at an appropriate timing.

The log information includes the measurement result and the corresponding exact location of the Log. Application scenario 2: IMD MDT application

FIG. 4 is a schematic flowchart of a method for feeding back MDT measurement information in an IMD MDT measurement scenario according to an embodiment of the present disclosure, where the method specifically includes the following steps:

Step S401: The terminal device receives the IMD MDT measurement configuration information in the connected state. In practical applications, the MDT measurement configuration message is an RRC Connect Reconfiguration message.

In the above process, the MDT measurement configuration message carries a requirement for providing accurate location information to the terminal device, that is, minimum location interval information, for example, 20 m.

Step S402: The terminal device determines whether the interval between the current location and the last reported location reaches the minimum location interval information.

If it is not reached, that is, the accurate location information update obtained by the terminal device through the positioning technology such as GNSS or LCS and the location information interval triggered by the last location information triggering are less than 20 m, step S403 is performed. If it is reached, that is, the accurate location information update obtained by the terminal device through the positioning technology such as GNSS or LCS and the location information interval triggered by the last location information triggering are greater than 20 m, step S404 is performed.

Step S403: The terminal device does not trigger the measurement reporting behavior.

Step S404: The terminal device triggers the measurement reporting behavior, and reports the measurement result to the network side.

The wireless signal quality measurement result (for example, the downlink pilot information of the camping cell) is recorded at the same time, and the RF fingerprint information is not included. It should be further pointed out that the configured minimum position interval information can be updated according to the needs of the network side for different precise location information.

For example, in the initial stage of network deployment, operators want to obtain MDT information with large granularity of location information. Therefore, when configuring MDT measurements (including LOG MDT or IMD MDT) for terminal devices, you can configure a relatively large minimum interval value, for example, 200m.

In the later stage, when it is necessary to perform precise network optimization for the hotspot area, a smaller minimum position interval value, for example, 20 m, may be configured.

The configuration information is sent by the base station (eNB) to the terminal device in the connected state, but these requirements are all from the 0 AM node, and are transmitted from the OAM to the eNB through different trace modes (management based trace or signalling based trace).

By applying the technical solution proposed by the embodiment of the present invention, the network side device notifies the terminal device of the need for the accurate location information record, so that the terminal device performs the MDT measurement when the current location reaches the corresponding accurate location information record requirement.
