Abstract
The present invention aims to provide the radio access network system which can analyze a fault during call processing by a mobile terminal. A control equipment for controlling calls for a mobile terminal and a relay equipment for relaying control signals between the mobile terminal and the control equipment monitor control signals during the call processing for the specified mobile terminal. A data collection and analysis equipment receives and processes those monitored control signals for a fault analysis.
Claims9
A radio access network system which gives an analysis of fault for radio communications of a mobile terminal, the system comprising:
- a control equipment for controlling calls for the mobile terminal, which receives a signal analysis request command with a user identifier to be monitored, outputs a signal monitor request including the user identifier and performs monitoring operation for control signals of calls related to the mobile terminal specified by the user identifier in accordance with the signal analysis request command, and outputs monitored control signals when the monitoring operation has been completed;
- a relay equipment for relaying control signals between the mobile terminal and the control equipment, which receives the signal monitor request, performs monitoring operation for control signals of calls related to the mobile terminal specified by the user identifier in accordance with the signal monitor request, and outputs monitored control signals when the monitoring operation has been completed;
- and
- a data collection and analysis equipment, which receives monitored control signals output from the control equipment and the relay equipment, combines the monitored control signals from the control equipment and the monitored control signals from the relay equipment based on the user identifier, reorders the combined control signals based on time index attached to respective control signals, and outputs the reordered control signals for fault analysis.
A method of fault analysis for a radio access network system provided with a mobile terminal, a control equipment for controlling calls for the mobile terminal, a relay equipment for relaying control signals between the mobile terminal and the control equipment, and a data collection and analysis equipment for data processing, the method comprising:
- receiving a signal analysis request command, at the control equipment, with a user identifier which specifies the mobile terminal to be monitored;
- transmitting a signal monitor request, from the control equipment to the relay equipment, including the user identifier which has been received with the signal analysis request command;
- performing monitoring operation, at the control equipment, for control signals of calls related to the mobile terminal specified by the user identifier in accordance with the signal analysis request command;
- receiving the signal monitor request, at the relay equipment;
- performing monitoring operation, at the relay equipment, for control signals of calls related to the mobile terminal specified by the user identifier in accordance with the signal monitor request;
- transmitting monitored control signals, from the respective control equipment and relay equipment to the data collection and analysis equipment, when the monitoring operation has been completed;
- combining the monitored control signals received from the respective control equipment and relay equipment based on the user identifier, at the data collection and analysis equipment;
- reordering the combined control signals based on time index attached to respective control signals, at the data collection and analysis equipment;
- and
- outputting the reordered control signals, from the data collection and analysis equipment, for fault analysis.
