Abstract

A method, device and system for automatically switching voice call services are described which are capable of intelligently determining IP network service authority states and data connection states of a current calling party and a called party through the cooperation of a terminal and an IP network service server when a user initiates a voice call based on a PLMN network and automatically switching the voice call of the PLMN network to a voice call service of an IP network when the states of the calling party and the called party both meet a set switching condition. By bearing the current call with the IP network instead of the PLMN network, the method, the device and the system disclosed herein achieve the purposes of improving call quality and saving call fee.

1. A method for automatically switching voice call services, comprising:

when a calling terminal initiates a call aiming at a called terminal through a Public Land Mobile Network (PLMN), sending, by the calling terminal, an IP service query message containing identification information of the calling terminal and the called terminal to an Internet Protocol (IP) network service server;

querying, by the IP network service server, states of the calling terminal and the called terminal, and sending a switching selection prompt message to the calling terminal and the called terminal when the states of the calling terminal and the called terminal meet a preset call switching condition;

establishing, by the IP network service server, an IP network connection path between the calling terminal and the called terminal when the calling terminal and the called terminal both select to switch the call, and notifying the calling terminal and the called terminal of establishing the IP network connection path;

after the notifying, breaking, by the calling terminal, a call connection with the PLMN network, and making an IP network call with the called terminal by using the IP network connection path.

2. The method according to claim 1, wherein the meeting the preset call switching condition comprises:

service authority states of the calling terminal and the called terminal are both of registered IP network call services, and data connection states of the calling terminal and the called terminal are both activated states.

3. The method according to claim 2, wherein the situation that the data connection states are the activated states comprises:

a cellular network is started and in the activated state, or a Wireless Local Area Network (WLAN) is started and in the activated state.

4. The method according to claim 1, 2 or 3, further comprising:

when the calling terminal sends the IP service query message to the IP network service server, detecting, by the calling terminal, whether or not a current data connection state thereof is an activated state; and

then sending, by the calling terminal, the IP service query message to the IP network service server when the current data connection state thereof is the activated state; and

after the IP network service server receives the IP service query message, querying, by the IP network service server, a service authority state of the calling terminal and service authority and data connection states of the called terminal.

11. The method according to claim 2, further comprising:

when the calling terminal sends the IP service query message to the IP network service server, detecting, by the calling terminal, whether or not a current data connection state thereof is an activated state; and

then sending, by the calling terminal, the IP service query message to the IP network service server when the current data connection state thereof is the activated state; and

after the IP network service server receives the IP service query message, querying, by the IP network service server, a service authority state of the calling terminal and service authority and data connection states of the called terminal.

12. The method according to claim 3, further comprising:

when the calling terminal sends the IP service query message to the IP network service server, detecting, by the calling terminal, whether or not a current data connection state thereof is an activated state; and

then sending, by the calling terminal, the IP service query message to the IP network service server when the current data connection state thereof is the activated state; and

after the IP network service server receives the IP service query message, querying, by the IP network service server, a service authority state of the calling terminal and service authority and data connection states of the called terminal.

5. A terminal for automatically switching voice call services, comprising:

a calling module, a switching selection module and an IP network call module, wherein the calling module is configured to send an IP service query message containing identification information of a calling terminal and a called terminal to an Internet Protocol (IP) network service server when initiating a call aiming at the called terminal through a Public Land Mobile Network (PLMN), and to break a call connection with the PLMN network based on the triggering of the IP network call module;

the switching selection module is configured to receive and display a switching selection prompt message sent from the IP network service server, and to send a selection result of a user to the IP network service server; and

the IP network call module is configured to trigger the calling module after receiving a notification message of establishing an IP network connection path by the IP network service server for the calling terminal and the called terminal, and to make an IP network call between the calling terminal and the called terminal by using the IP network connection path.

6. The terminal according to claim 5, wherein the calling terminal is further configured to detect whether or not a current data connection state thereof is an activated state when sending the IP service query message to the IP network service server, and to send the IP service query message to the IP network service server when the current data connection state thereof is the activated state.

7. An Internet Protocol (IP) network service server, comprising:

an IP network service module, which is configured to query states of a calling terminal and a called terminal after receiving an IP service query message, and to send a switching selection prompt message to the calling terminal and the called terminal when the states of the calling terminal and the called terminal meet a preset call switching condition; and

a path establishment module, which is configured to establish an Internet Protocol (IP) network connection path between the calling terminal and the called terminal when the calling terminal and the called terminal both select to switch a call, and to notify the calling terminal and the called terminal of establishing the IP network connection path.

8. The IP network service server according to claim 7, wherein the meeting the preset call switching condition in the IP network service module comprises:

service authority states of the calling terminal and the called terminal are both of registered IP network call services, and data connection states of the calling terminal and the called terminal are both activated states.
