The technical field
The present invention relates to a device and method for receiving an emergency call, and more particularly to a device and method for receiving an emergency call when the limits of a class network access.
In modern systems, GSM (global system for mobile communications) and 3GPP (Project partnership in creating systems of the third generation) cellular phone, the mobile phone may place an emergency call in the network, even if access to other calls is limited by the network within the time constraints of the class access. The network may initiate the class b limits access for various reasons. For example, some base stations in this area can be damaged, which leads to an overload, or there may be a condition of emergency such as an earthquake or fire, when the network may reject the access for normal calls and allow access only for emergency calls. Access is controlled by the network by assigning a class of access in the range from 0 to 9 all mobile phones, as described in the technical specifications 3GPP TS 22.011 V4.8.0 (2002-09). Class 10 access is signaled by the network to mobile phones over the air, to indicate whether network access for emergency calls cell is determined as being the phone with classes access from 0 to 9. Within the time constraints of the class access network prohibits mobile phones belonging to restricted classes of access, access to the network for placing and receiving a call, although access to the network for emergency calls allowed if the access class 10 is not prohibited by the network. However, making an emergency call, the mobile phone that does not belong to one of the allowed access class still does not have permission to accept the call within the time constraints of the class access. For example, the callback from the provider of emergency services is prohibited, even if it relates to an emergency call.

After receiving wireless signals, the device 100 detects wireless received by antenna 102 signals for the formation of the detected speech signals and/or data signals. The transceiver 104 associated with the antenna 102, converts the detected signals into electrical signals of the base band and demodulates the electrical signals of the base band to recover incoming information, such as speech and/or data transmitted wireless signals. After receiving the incoming data from the transceiver 104, the processor 106 formats the incoming information for output to the display 108 and/or the tool 112 audio input and output. Similarly, for transmitting wireless signals, the processor 106 formats the outgoing information and sends it to the transceiver 104 to modulate the carrier and transformation in the modulated signals. The transceiver 104 sends the modulated signals to the antenna 102 for transmission to a remote receiving the transmitter (not shown).

The processor 106 compares the class access broadcast network to check whether the class 10 access initiated before the eat an emergency call. If an emergency call is assigned a channel for communication, thereby providing access to the network, the circuit 116 synchronization marks the point in time, a channel number is assigned as the beginning of a predefined time interval and begins to track elapsed time. Within a predefined time interval, the CPU 106 accepts an incoming personal call, provided that the network allowed class 10 access. Until the CPU 106 determines that the elapsed time has exceeded a predetermined time interval, the processor 106 provides the ability to receive incoming calls when the functioning of the network with the limits for class access.
Figure 2 shows an illustrative flowchart 200 describing the operation of the wireless communication device 100 in accordance with the first embodiment. The process begins in block 202, and the device 100 wireless controls the installation of the current class access in block 204. If you initiated the call, the device 100 wireless determines in block 206 whether the call is an emergency call. If the call is not an emergency call, the device 100 performs wireless communication regular processing in block 208, and the processing ends in block 210. If the call is an emergency call, the device 100 wireless set is no in block 212, whether or not you currently have a class 10 access. If class 10 access is not enabled, the device 100 wireless completes the call by rejecting the call in block 214, and the process ends in block 210. However, if the call is an emergency call, and class 10 access is allowed, the device 100 performs wireless communication connection of the call in block 216. Then the device 100 wireless begins to monitor incoming calls within a predetermined time interval in block 218, and the process ends in block 210.

After block 216 passed an emergency call device 100 wireless control channel assignment for the call in block 302, and may re-attempt to implement an emergency call on a specified number of times in block 304, if the channel is not assigned to an emergency call, i.e. if the call is unsuccessful. If the call is assigned a channel, the device 100 wireless marks the beginning of a predefined time interval and begins in block 306 tracking elapsed time in a predefined time interval. In block 308 checks exceeded if the elapsed time is a predetermined time interval, for example, 45 minutes or some other the stipulated duration of time. If the elapsed time is within a predefined time interval, the device 100 wireless continues to block 310 to answer incoming calls in accordance with the class of access in an emergency and continues to control block 308 elapsed time. Upon expiration of a predefined time interval, the device 100 for wireless communication at step 210 ends the process. Monitoring the elapsed time can be performed using the internal clock of the wireless communication device 100 or by receiving time information from an external time source, such as a network time source. The predefined time interval can be defined as current from time perform a successful destination channel or from the time of completion of the emergency call. The predefined time interval may be updated after initiation of a new emergency call to the provider of emergency services or after receiving a callback from the provider of emergency services.

If the incoming call is not addressed to the device 100 for wireless communication, then the process repeats from block 402. If an incoming call addressed to the device 100 of the wireless communication device 100 wireless determines in block 408 whether the class 10 call at the moment. If class 10 call is not currently enabled, then the device 100 wireless is not responsible for prospecting call, and the process returns to block 308. If class 10 call currently enabled, then the device 100 wireless determines in block 410, whether the priority level of the incoming call high, which may indicate that the information included in this search call. If the priority level is high, indicating that the incoming call is a call associated with an emergency situation, the device 100 wireless answers the call in block 412, and processes the call in block 414. The process then returns to block 308. If the priority level is not high, the device 100 wireless is not responsible for prospecting call, and the process returns to block 308. Alternatively, if the class 10 access currently allowed, the device 100 wirelessly with the ne may first answer search call then to determine whether the priority level of the incoming call is high, using information received after the response to the search call. If the priority level is high, the device 100 wireless handles the call, and then the process returns to block 308. If the priority level is not high, the process returns to block 308 without processing the call.
