Usually, when people dial 110 to call the police, they are often getting too nervous to tell their exact position, which directly results in the delay of rescue. At present, as a result of the cooperation between Ningbo China Mobile and Municipal Public Security Bureau, from now on, when citizen report to the police at 110 and 122 through mobile phone, the police can find the position of the reporter in 2 seconds. According to the introduction of engineers of China Mobile Ningbo branch, the position system of mobile phones has played a huge role during the Beijing Olympics. Since there are large numbers of guests from both home and abroad who are not familiar with Beijing, when they get lost or encounter car accidents, they can not tell the exact position of themselves. To cope with this problem, Beijing Traffic Administration can tell the location of the reporter in 2 seconds through an intelligent traffic management system. Now this technology is being popularized all over the country. When the call of the reporter is put through, the system will immediately send the mobile phone number to Mobile telecom carrier, who can find the latitude and longitude of the mobile phone and sent back to the police.
