Embodiment 1

[0043] In this embodiment, the network-side device carries the RLF measurement reporting indicator through a dedicated message (configuration message) to implement coverage-optimized measurement control. The specific process is as follows: Figure 4 shown, including the following steps:

[0044] Step 400: When the network side device sends a configuration message to the UE, the configuration message, for example: RRC Setup Request (RRCConnectionSetup) or RRC Reconstruction Request (RRCConnectionReconfiguration) carries an RLF measurement report indicator (such as: ReportOnRLF) to instruct the UE When RLF occurs, report the RLF measurement report;

[0045] In this step, when the network side device (referred to as eNB in ​​this embodiment) receives the RRC establishment request initiated by the UE, the eNB sends a configuration message to the UE according to the identifier of the UE in the RRC establishment request, and in the configuration message (such as: RRCConnectionSetup ...

Embodiment 2

[0053] In this embodiment, the network side device implements the RLF measurement report indication by configuring the message to carry the event (Event), and realizes the measurement control of coverage optimization. The specific process is as follows Figure 5 shown, including the following steps:

[0054] Step 500: The network side device adds an event Event A6 dedicated to triggering the RLF measurement report in the measurement report configuration message ReportConfigEUTRA in the configuration message sent to the UE (that is, instructs the UE to trigger the reporting of the RLF measurement report when RLF occurs);

[0055] Step 501: After receiving the configuration message sent by the network-side device, the UE reads and parses the EventA6 information. When RLF occurs in the UE, it will trigger Event A6 (that is, the UE reports the RLF measurement report through the subsequent reconstruction process or independent message flow) ;

[0056] Step 502: The network side de...

Embodiment 3

[0061] In this embodiment, the network-side device carries the RLF measurement reporting indicator through a public message (such as a broadcast message) to implement coverage-optimized measurement control. The specific process is as follows: Image 6 shown, including the following steps:

[0062] Step 600: The network side device carries an RLF measurement report indicator (such as: ReportOnRLF) in a broadcast message (such as: SIB1), which is used to instruct the UE to report an RLF measurement report when RLF occurs;

[0063] Step 601: When the UE resides in a cell or needs to read the broadcast message of the system during the service establishment process, read the broadcast message, parse the RLF measurement report indicator in it, and when the UE has RLF, report it according to the RLF measurement Indicate the identity and send the RLF measurement report to the network side device;

[0064] Step 602: The network side device receives the above-mentioned RLF measurement ...

Abstract

The invention discloses a method and a system for the measurement control of coverage optimization, which relate to a 3rd generation partnership project (3GPP) long term evolution (LTE) mobile communication system. The method comprises the following steps of: reporting a radio link failure (RLF) measurement report to network-side equipment after the network-side equipment indicates that user equipment (UE) has the RLF; and judging whether a region where the UE is located has a coverage hole according to the RLF measurement report when the network-side equipment receives the RLF measurement report reported by the UE. By adoption of the technical scheme provided by the invention, the network-side equipment can judge whether the RLF is caused by a coverage problem according to the information of the RLF measurement report sent by the UE, thereby further optimizing the coverage process of a network.

Description

technical field [0001] The present invention relates to a 3GPP Long Term Evolution (LTE, Long Term Evolution) mobile communication system, in particular to a measurement control method and system for coverage optimization. Background technique [0002] Currently, LTE networks such as figure 1 As shown, it is composed of (E-UTRAN, Evolved UTRAN) base station eNB (Evolved NodeB) and evolved packet switching center (EPC, Evolved Packet Core), and the network is flat. The E-UTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2. S1 and X2 are logical interfaces. One EPC can manage one or more eNBs, one eNB can also be controlled by multiple EPCs, and one eNB can manage one or more cells. [0003] Self-Organizing Network (SON, Self-Organizing Network) is a technology for automatic network configuration and optimization. The feature of this technology is self-configuration and self-optimization. The application ...
