Service connection apparatus and method in portable terminal
A call connection method and apparatus are disclosed. When a service is released in a portable terminal that supports different communication modes due to a network problem, the call connection method and apparatus reconnects the service to another network. The call connection method includes performing a first service through a first network, analyzing, when the connected first service is released, the cause of disconnection, acquiring, when the cause of disconnection is a problem in the first network, connection information, and attempting to connect a second service through a second network based on the connection information.
1. A call connection method in a portable terminal that supports multiple wireless communication technologies, the method comprising:
establishing a connection with a first network supporting a first wireless communication technology;
performing a first service over the first network;
acquiring connection information of a second network when the evaluated strength of a signal received from a base station of the first network is a predetermined condition;
establishing a connection with the second network supporting a second wireless communication technology based on the acquired information; and
performing a second service over the second network,
wherein the first service is a video call, and
wherein the second service is a voice call.
2. The method of claim 1 , wherein the predetermined condition includes radio link failure.
3. The method of claim 1 , wherein the predetermined condition includes handover failure.
4. The method of claim 1 , wherein the predetermined condition includes a condition that the evaluated strength of the signal received from the base station of the first network is less than a predetermined level.
