Description

Method and apparatus for reporting and reporting MDT measurement results The present application claims to be submitted to the Chinese Patent Office on May 10, 2012, the application number is 201210144569.6, and the invention name is "a method and device for reporting and reporting MDT measurement results" Priority of Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and apparatus for minimizing road test MDT measurement results. Background technique

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 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 desirable to adopt a network configuration user terminal (User Equipment, UE) reporting method to reduce the manual road test. 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. For the above reasons, in version 10 (Release-10, el-10) (including Long Term Evolution (LTE) systems and Universal Mobile Telecommunications System (UMTS)), minimization of drive test (Minimization) Drive Test, MDT) was introduced.

The MDT measurement classifications introduced by Rel-10 are:

1) Immediate MDT (Instant MDT): MDT measurement and uplink H multiplexed Radio Resource Management (RRM) measurement mechanism in the connected state. Once the reporting condition is met, immediately to the evolved base station.

(Evolved NodeB, eNB) / Radio Network Controller (RNC) performs the above.

2) Stored MDT (Logged MDT): The MDT measurement performed in the idle state is reported in the subsequent connected state. If the UE in the idle state meets the configured trigger condition, it will obtain the measurement result and store it (log). After entering the connected state, it will report it to e B/RNCo at the appropriate time.

The Logged MDT is described in detail below.

The log configuration for configuring the UE to trigger the MDT measurement in the idle state is sent by the network side to the UE in the connected state. After receiving the log configuration message, the UE performs the corresponding MDT measurement collection according to the configuration, and The collected measurement result (log result) is stored on the UE side. After entering the connected state, it waits for the network notification and then reports it. Specifically, in the case of the Logged MDT, when the UE stores the available log result, if entering the connected state or moving to the new cell, the UE will use the Log available indicator to pass the Radio Resource Control (RRC). The signaling is reported to the network.

Taking the LTE system as an example, after the UE successfully establishes an RRC connection, the UE will send an RRC connection to the network. The completion message is in this case, and the message carries the indication information of whether the UE saves the available log result. After receiving the indication information, the network determines that the log result is stored in the UE, and may subsequently request the UE to report the saved log result. Similarly, in the handover and re-establishment process of the LTE, if the UE saves the log result, the log available indication is sent to the handover target cell/reconstructed cell, and the presence of the available log result of the new cell is notified. In the UMTS system, if a Serving Radio Network Subsystem (SRNS) relocation procedure occurs, the UE also sends a log available indication to the updated target cell.

After receiving the log available indication, the network side may request the UE to report the stored Logged MDT result by using the UE information reporting process. The specific process is shown in Figure 1. The network side sends the UE information request UE Information Request message to the UE, and the UE receives the message. After the request message, the UE information is used to respond to the measurement result on the UE Information Response message.

At present, the measurement result of the Logged MDT of the UE in the UE Information Response message includes: - the cell global ID of the serving cell, the cell global ID and the measured quantity;

- other cell measurement (including the same frequency / different frequency / idle technology (idle) state available measurement results); - timestamp information.

Since the terminal performs MDT measurement, it is important to record the geographical location information of the measurement, so Rel-11

One goal in the MDT is to enhance geographic location information.

In Rel- 11, in order to obtain detailed geographical location information, the principle of detailed geographical location information based on the request is introduced. At present, Rel-11 MDT has already started discussions, and it is clear that detailed geography is required for both Immediate MDT and Logged MDT. Location information is enhanced, but there is no conclusion as to how the Logged MDT can be enhanced. The Rel-11 requirements for MDT cannot be met. Summary of the invention

The method and apparatus for reporting and reporting MDT measurement results provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

In Rel-11 (LTE and UMTS systems), it is required to obtain the corresponding geographic location information while obtaining the MDT measurement. However, in the case of Logged MDT, in Rel-10, the system's MDT requirements cannot be met.

The present invention proposes a method for measuring MDT measurement results, as shown in FIG. 2, including:

In step 201, the UE determines that the network side requests to perform the request-based detailed geographic location information reporting, and when the idle state-based positioning function obtains the detailed geographical location information, stores the detailed geographical location information, and performs step 202;

Step 202: When receiving the request from the network side, the UE simultaneously sends the MDT measurement result and the detailed geographic location information obtained in the idle state to the network side.

The network side request received by the UE, specifically, the MDT measurement result report request, such as the existing UE information request UE Information Request message.

Specifically, the UE performs MDT measurement in an idle state according to the configuration information sent by the network side, and the obtained MDT measurement is performed. The result is stored.

The idle state performs the MDT measurement for the Logged MDT measurement. Specifically, the existing mechanism may be adopted. For the Logged MDT measurement, the network side sends configuration information indicating that the UE performs the idle state MDT measurement in the connected state to the Logged MDT measurement, which may be With the existing mechanism, the UE subsequently enters the connected state and receives the MDT measurement result report request from the network side.

The embodiment of the present invention is based on the requirements of the network side. If the network side requests to perform the detailed geographic location information reporting based on the request, the UE may determine the detailed geographic location information when the idle location is enabled and the detailed geographic location information is obtained. The detailed geographical location information is reported to the network side. The geographical location information is obtained by the UE to enable the location function, and thus is the detailed geographical location information, thereby solving the collection and the detailed geographical location information of the idle state UE when performing the Logged MDT. · 艮艮 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Preferably, the positioning function opened by the UE in the embodiment of the present invention may be, but is not limited to, a Global Navigation Satellite System (GNSS) function.

For the UE, if the UE has GNSS functions, such as Global Positioning System (GPS), the GPS can be directly used to obtain the current location of the UE. This is called standalone GNSS positioning. In addition, the network can also provide some auxiliary information for GPS module positioning, such as the network-assisted global satellite navigation system positioning method (GANSS/A-GNSS) in UMTS.

Preferably, in the embodiment of the present invention, the RNC/eNB on the network side sends configuration information to the UE.

The MDT measurement result reporting method provided by the embodiment of the present invention can be applied to the LTE system and the UMTS system. If applied to the LTE system, the eNB sends configuration information to the UE. If applied to the UMTS system, the RNC sends the configuration to the UE. information.

Preferably, the UE may be configured to pre-approve that the UE that supports the positioning function performs the request-based detailed geographical location information (requested location info for MDT), which is an implicit indication manner; or the UE receives the network side request before receiving The indication sent by the network side to perform the report based on the detailed geographical location information of the request is an explicit indication manner.

The network side requires the execution of the request-based detailed geographic location information reporting, which means that the UE obtains the detailed geographic location information in the idle state while determining the MDT measurement result obtained in the idle state based on the network side request. The MDT measurement result and the detailed geographical location information are simultaneously sent to the network side.

In this embodiment, the UE determines, according to the pre-agreed or the indication information sent by the network side, whether the network side requests to perform the detailed geographic location information reporting based on the request.

In this way, when the UE determines that the network side requests to perform the detailed geographic location information reporting based on the request, the UE performs step 202. Preferably, the RNC/eNB on the network side sends the indication information to the UE. If applied to the LTE system, the eNB sends the indication information to the UE. If applied to the UMTS system, the RNC sends the indication information to the UE. In the configuration signaling sent by the UE from the network side, the UE receives the indication information sent by the network side and the idle state MDT measurement configuration information. For example, the e B/RNC adds an indicator to the log configuration signaling as the indication information indicating that the network side requests the UE to perform the request-based detailed geographic location information reporting.

Preferably, the UE that uses the same protocol to communicate in advance supports the positioning function, which is an implicit reporting mode; or when the UE part that uses the same protocol supports the positioning function, the UE that supports the positioning function goes to the network side. The UE supports the locating function, which is an explicit reporting mode, whether it is an implicit or an explicit reporting mode. The purpose is to enable the network side to send the indication information to the UE supporting the positioning function when transmitting the indication information.

Specifically, if the UE that uses the same protocol to communicate in advance supports the locating function, the UE that is required to support the locating function on the network side performs the request-based detailed geographic location information reporting, for example, the UE that is scheduled to use the Rel-11 version supports positioning. The function is to report the detailed geographical location information based on the request. In this way, when the UE reports the MDT measurement result according to the agreement, if the detailed geographical location information is obtained, the UE reports the information at the same time. Or the network side sends the indication information to the UE according to the requirement, so that the UE that receives the indication information reports the detailed geographical location information when the MDT measurement result is reported.

If the UE part that uses the same protocol supports the positioning function, the UE does not know which UEs support the positioning function, and the UE that supports the positioning function supports the positioning function to the UE on the network side. That is, the network side can know from which UEs to obtain the detailed geographical location, and can pre-arrange the UE to support the positioning function to perform the request-based detailed geographical location information, and can also select to send the indication information to the partial UEs as needed.

Preferably, if the UE capability information carries the capability of supporting the positioning function or the UE supports the real-time MDT based on the request, the network side determines that the UE supports the positioning function, where the UE supports the positioning function, that is, The UE supports the detailed geographic location information reporting capability based on the request.

Preferably, the UE determines that the network side requests to perform the request-based detailed geographic location information reporting, and timestamps the obtained MDT measurement result when performing the MDT measurement in the idle state; and does not actively turn on the positioning function when performing the MDT measurement in the idle state, Obtain detailed geographic location information when triggered to enable the positioning function, and timestamp the obtained detailed geographical location information. When reporting the MDT measurement result and detailed geographical location information obtained in the idle state, the MDT measurement result and the detailed geographical location are also reported. The timestamp corresponding to the information. In this embodiment, the MDT measurement and positioning are performed separately, and each time an MDT measurement result or detailed geographical location information is collected, a corresponding time stamp is applied. The time that the UE is in the idle state is relatively long. If the UE supports the positioning function, the positioning function is usually triggered for other reasons.

When the UE is triggered to enable the positioning function, the detailed geographical location information is collected in a set period. The setting period is less than the positioning function time and the difference from the MDT measurement period is less than the set threshold. The positioning time is usually longer, and the positioning time is longer. In order to obtain more detailed geographical location information, try to collect geographical location information close to the MDT measurement cycle.

Preferably, when reporting the timestamp corresponding to the MDT measurement result and the detailed geographical location information respectively, the two differences are The value 'J, the MDT measurement result corresponding to the time stamp of the set time difference and the detailed geographical location information use the same timestamp, which can reduce the signaling overhead.

The embodiment of the present invention further provides a method for minimizing the indication of the road test MDT measurement result, including: configuring the user terminal UE to perform MDT measurement in an idle state, and transmitting configuration information to the UE; and sending an indication request to the UE The UE performs indication information reported by the detailed geographic location information of the request. Preferably, the network side sends the configuration information and the indication information to the UE at the same time by configuring signaling.

Preferably, the UEs that use the same protocol to communicate in advance support the positioning function, or when the UE part that uses the same protocol communication supports the positioning function, the UE that receives the positioning function is received.

When the indication information is sent, the indication information is sent to the UE supporting the positioning function.

Preferred embodiments of the present invention are given below in conjunction with the network side and the UE.

Example 1

In the LTE system, when the UE determines that the positioning function is supported, the UE reports the capability of the requested location info for MDT (explicit reporting) to the eNB; the eNB performs Logged MDT measurement configuration on the UE, and simultaneously An indicator is added to the log configuration signaling to indicate that the UE performs the detailed geographic location information reporting based on the request while performing the Logged MDT.

After receiving the log configuration signaling, the UE records the Logged MDT measurement result (excluding detailed geographical location information) within the Logged MDT measurement time according to the configured content, and time stamps the MDT measurement result. At the same time, the UE actively activates the GNSS positioning function for the MDT in the idle state, and records the detailed geographical location information obtained every time when the GNSS positioning result is triggered by other reasons.

Further, in order to obtain more detailed geographical location information, when the UE starts the positioning function for other reasons, the UE performs detailed geographical location information collection in a shorter period (as close as possible to the collection period of the MDT measurement amount). Serve for MDT. For example, for other reasons, the positioning frequency is 1 minute/time, the total positioning time is 10 minutes, and the collection period of the Logged MDT measurement is 10.24 seconds. In the 10-minute positioning time, the UE performs the cycle at 10.24 seconds. Position, get the positioning result, used for MDT.

The UE obtains the Logged MDT measurement amount and the detailed geographical location information respectively, and then respectively time stamps. When the UE needs to perform the MDT measurement result, the UE reports the collected detailed geographical location information and its timestamp, and the MDT measurement result and its timestamp as the content in the MDT result report to the e. B. Further, in order to reduce the signaling overhead, in the reporting signaling, the detailed geographical location information of the same/near time stamp and the MDT measurement result may be put together, and a time stamp may be used.

Then the UE supports GNSS.

The eNB performs a Logged MDT measurement configuration on the UE, and adds a indicator to the log configuration signaling to indicate that the UE performs the Logged MDT and also performs detailed information based on the request.

After receiving the log configuration signaling, the UE records the Logged MDT measurement result in the Logged MDT measurement time according to the configured content, and timestamps the result. At the same time, the UE does not actively enable the GNSS positioning function for the MDT purpose, but when the GNSS positioning result is triggered by other reasons, the obtained detailed geographical location information is recorded and time stamped.

The UE obtains the Logged MDT measurement amount and the detailed geographical location information respectively, and then respectively time stamps. When the UE needs to perform the MDT measurement result, the UE reports the collected geographical location information and its timestamp, and the MDT measurement result and its timestamp as the content in the MDT result report, and reports the content to the MDT result report.

The Logged MDT measures the results and time stamps the results. At the same time, the UE does not actively enable the GNSS positioning function for the MDT purpose, but when the GNSS positioning result is triggered by other reasons, the obtained detailed geographical location information is recorded and time stamped. Further, in order to obtain more detailed geographical location information, when the UE starts the positioning function for other reasons, the UE performs detailed geographical location information collection in a shorter period (as close as possible to the collection period of the MDT measurement amount).
