发明名称 Supporting data roaming in GPRS networks
摘要 A method and apparatus for supporting data connectivity with a roaming partner when a communication device is outside a service provider's range of coverage is provided. In one aspect, a user can select and store a roaming partner that is capable of data communication. While roaming, the communication device will display the data-roaming partners that are currently available within the communication range of the device and the user can choose one of these data-roaming partners and store the data-roaming partner information in memory. Upon re-entering the region within communication range of that roaming partner, the device can communicate with the roaming partner of choice rather than the roaming partner ordinarily selected by the device as a default.
