Method for determining whether data service connectivity is supported in a wireless communication system

摘要

A method for a wireless device to automatically and dynamically determine if the current system in which it is operating is capable of offering data service connectivity. The present invention requires no intervention on the part of the user. According to the method of the present invention, a call origination signal from a wireless device is automatically transmitted to a base station. The call origination signal contains a request for electronic data transmission services. The wireless device detects whether a reply to the call origination signal has been received from the base station. If a reply has been received, the wireless device detects whether the data service request has been rejected. If the detected reply does not reject the data service request, then an indication of availability of the data service is displayed on the wireless device. If the detected reply does reject the data service request, then an indication of non-availability of the data service is displayed on the wireless device.
