A method for controlling antennas in a vehicle having an external antenna and an internal antenna includes triggering an eCall service function upon sensing an accident occurrence event, measuring a quality of one or more wireless signals received through the external antenna, comparing the measured quality of the wireless signals with a reference quality value, and selecting one of the external antenna and the internal antenna to be used in the eCall service function based on the results of the step of comparing the measured quality of the wireless signals with the reference quality value. A system of emergency communication of a vehicle is also provided.

A device for preventing an eCall system backup battery for a vehicle from discharging is provided. The device includes a GPS configured to provide current position information of the vehicle in which an eCall system is mounted. A sales area information storage is configured to form and store the GPS information on all sales areas as a sales area information database. A microcomputer is configured to determine whether the vehicle is located within a sales area which is a final destination by using the information acquired from the GPS module and the sales area information storage and to control whether the backup battery operates depending on the determination result. A power supply manager is configured to select and manage any one of a main battery and the backup battery as supply power of the eCall system by a control of the microcomputer.

A method and a device for triggering an emergency call in a vehicle equipped with an airbag. The device can be retrofitted in a vehicle equipped with an airbag to provide an emergency system which, in the event of an airbag being triggered, sends an emergency call (Ecall) to a suitable emergency call center in order to initiate auxiliary measures as may be necessary.

The invention relates to a vehicle-mounted ECALL device alarm method with vehicle and personnel information detection, comprising the following steps: after the ECALL device is triggered, an alarm call is made to obtain the vehicle data information and personnel data information in the current state at the same time, and the vehicle data information and the vehicle personnel data information are simultaneously obtained. Summarize the data information of internal personnel; check whether the external network can be connected, and when the external network can be connected, start the network transmission module to encrypt and send the summarized data information to the emergency data platform; when the external network cannot be connected, encrypt the summarized data information through SMS Send to the emergency data platform; the emergency data platform aggregates the network information and SMS information sent by the same ECALL device, and sends the aggregated information to the alarm command center in the corresponding jurisdiction pointed by the vehicle positioning information; while making an alarm call It can provide rich and complete first-hand on-site vehicle and personnel information, and has good reliability, which can greatly improve rescue efficiency.

An eCall is an emergency call in which: (i) the emergency call may be initiated automatically by the wireless terminal or manually by the user due to a triggering event (e.g., the vehicle being involved in an accident); and (ii ) said emergency call includes additional data automatically sent by the terminal to a receiving entity (eg, a Public Safety Answering Point PSAP). Depending on the implementation, high priority is given to registering the in-vehicle system IVS in eCall-only mode with the mobile network using emergency setup signaling (eg emergency setup message) or location update messages. Immediately after an eCall emergency is triggered at the IVS, the IVS can get a higher priority from the mobile network. When requesting connection to a mobile network, the IVS can use one or more fields of the location update message to register with the network with higher priority.

The invention relates to the technical field of wireless communication, and especially relates to a method, device and system for supporting an emergency call eCall. The method, the device and the system are used for solving the problem in the prior art that a network side device cannot successfully send out eCall callback when a terminal and the network side device support both an IMS domain and a CS domain; wherein the method comprises following steps of after the terminal releases the eCall initiated to the network side device, starting a target timer; registering by the self-supported IMS domain; sending a notification message to the network side device; and monitoring whether the network side device initiates the eCall callback for the eCall or not within the timed duration of the target timer. According to the technical scheme, after the terminal starts the target timer, registering is carried out by the self-supported IMS domain; therefore, the network side device cannot initiate the eCall callback through the IMS domain; and UE can timely receive the eCall callback.
