Roaming control method for digital mobile telephone |
摘要 |
A roaming control method for a digital mobile telephone is provided which is capable of entering a call reception state in a shortest time even if different carriers (providers) in the same frequency band are used for mobile telephone services. A roaming control method for a digital mobile telephone in a call reception control scheme at a home network and a roaming network, includes the steps of: activating a perch channel having a level of a reception radio wave larger than a predetermined level to receive broadcast information; judging whether a network number contained in the received broadcast information coincides with a home network number, and if not coincident; checking whether a roaming network number preloaded in the digital mobile telephone coincides with the network number contained in the received broadcast information, and if coincident; and receiving a call via the perch channel.
