(渥太华2日加新社电)加拿大广播及通讯管理委员会(Canadian Radio-television and Telecommunications Commission)给无线通讯服务商1年时间，提升它们的911功能，确保警方、消防或救护车等紧急服务调派员，能找到来电求救者的位置。
若干人以手机打911求救后死亡，因为紧急服务调派员，无法知道来电者手机位置。加拿大广播及通讯管理委员会上月宣布设下限期，提升911系统。
委员会周一公布规例，要求手机服务商如罗渣士通讯(Rogers Communications)、研科传讯(Telus Mobility)或贝尔传讯(Bell Mobility)，在大部分以手机打911的电话，能在在半径10米至300米内，找出来电者的位置。
紧急服务接线生只能确定来电者的电话号码，以及最接近的手机信号塔位置，来电者的位置是在这座信号塔的服务范围内，在市区覆盖半径为4公里，郊区则为20公里。
委员会说，限期手机服务商至明年2月解决这个问题。委员会说，提升技术已经存在，只是需要安装。委员会说，一些地点的服务在限期前会有改善。
Cellphone suppliers must show 911 callers’ location by February 2010

The location of each caller who dials 911 from a cellphone within Canada must be available to emergency responders by this time next year, the CRTC says.
Canadian wireless service providers are being required to upgrade their 911 services by Feb. 1, 2010, to make that possible, the Canadian Radio-television and Telecommunications Commission (CRTC) confirmed Monday in a news release.
“The safety and security of Canadians will be greatly improved as a result,” said Konrad von Finckenstein, chairman of the commission, in a statement.
A number of people have died after making 911 calls from cellphones because emergency dispatchers could not tell where the person was. Sharmarke Warsame died outside Brooks, Alta., last fall after calling 911. He had been beaten and left in a field. Police found his body three days after the call was made.
Currently, 911 services show the position of the cellphone tower nearest the caller, but not their specific area or location. The wireless industry has proposed that Global Positioning System and triangulation technology be used to provide emergency responders with the caller’s location within a radius of 10 to 300 metres, the CRTC said.
Wireless providers may enable the 911 features before the deadline and the CRTC is encouraging them to do so.
The service providers will be required to inform their customers about the availability, characteristics and limitations of their upgraded 911 features.
Len Katz, the CRTC’s vice-chairman, telecommunications, had revealed in January that the February 2010 deadline for enhanced 911 services was coming.
According to the CRTC, there are 20 million wireless subscribers in Canada, and many 911 calls are made from cell phones.
The CRTC can require providers to make safety services available, but does not regulate cellphone rates.
Cellphone companies can charge a 911 fee, even in areas where there is no such service provided. The big three cellphone companies — Bell, Telus and Rogers — as well as local providers are facing class-action lawsuits over the 911 charge. The lawsuits claim the companies misrepresented to customers what the charge was for.
