Abstract

A multiparty call processing method and mobile terminal implemented with the multiparty call processing method is provided. A multiparty call processing method for a mobile terminal detects a call request to a first network, determines whether the mobile terminal is in a full state of the first network, and sends a call request message to a second network when the mobile terminal is in the full state of the first network.

Claims

1. A multiparty call processing method for a mobile terminal, comprising:

detecting a call request to a first network;

determining whether the mobile terminal is in a full state to the first network; and

sending a call request message to a second network when the mobile terminal is in the full state to the first network.

2. The multiparty call processing method of claim 1, wherein the full state is a state in which the mobile terminal is participating in a maximum number of multiparty call groups simultaneously, and each multiparty call group is a group of terminals participating in a multiparty call through one channel.

3. The multiparty call processing method of claim 1, wherein the full state is a state in which the mobile terminal is participating in a multiparty call in which a maximum number of multiparty call participants are joined simultaneously, and the multiparty call participants are all participants'"'"' terminals participating in the multiparty call.

4. The multiparty call processing method of claim 1, further comprising outputting a notification when the mobile terminal is in the full state to the first network.

5. The multiparty call processing method of claim 1, further comprising setting the mobile terminal to send the call request message to the second network when the mobile terminal is in the full state to the first network.

6. The multiparty call processing method of claim 1, further comprising sending the call request message to the first network when the mobile terminal is not in the full state to the first network.

7. The multiparty call processing method of claim 1, wherein the first network is a Code Division Multiple Access (CDMA) network, a Wideband CDMA (WCDMA) network, a General System for Mobile communications (GSM) network, or a Universal Mobile Telecommunications System (UMTS) network, the second network is a CDMA network, a WCDMA network, a GSM network, or a UMTS network.

8. A multiparty call service method for a mobile terminal, comprising:

determining whether a call status of the mobile terminal satisfies a call diverting condition when a first network receives a call request message sent to the mobile terminal;

sending the call request message with a diverted number of the mobile terminal from the first network to a second network when the call status of the mobile terminal satisfies the call diverting condition; and

sending the call request message with the diverted number from the second network to the mobile terminal.

9. The multiparty call service method of claim 8, further comprising setting a call diverting function of the mobile terminal.

10. The multiparty call service method of claim 9, wherein setting the call diverting function comprises registering the diverted number of the mobile terminal with the call diverting condition to the first network.

11. The multiparty call service method of claim 10, wherein the call diverting condition comprises at least one of busy line, no answer, unreachable, and full state properties.

12. The multiparty call service method of claim 8, wherein the call diverting condition is at least one of a busy line state in which the mobile terminal is on a busy line, a no answer state in which the mobile terminal does not answer, an unreachable state in which the mobile terminal is unreachable, and a full status in which the mobile terminal is in a full state.

13. The multiparty call service method of claim 12, wherein the full state is a state in which the mobile terminal is participating in a maximum number of multiparty call groups simultaneously, and each multiparty call group is a group of terminals participating in a multiparty call through one channel.

14. The multiparty call service method of claim 12, wherein the full state is a state in which the mobile terminal is participating in a multiparty call in which a maximum number of multiparty call participants are joined simultaneously, and the multiparty call participants are all participants'"'"' terminals participating in the multiparty call.

15. The multiparty call service method of claim 8, further comprising establishing a call session with the first network when the call status of the mobile terminal does not satisfy the call diverting condition.

16. The multiparty call service method of claim 8, wherein the first network is a Code Division Multiple Access (CDMA) network, a Wideband CDMA (WCDMA) network, a General System for Mobile communications (GSM) network, or a Universal Mobile Telecommunications System (UMTS) network, the second network is a CDMA network, a WCDMA network, a GSM network, or a UMTS network.

17. A mobile terminal, comprising:

a first radio frequency unit to interface with a first network;

a second radio frequency unit to interface with a second network;

a first subscriber identity card that contains subscriber information for the first network;

a second subscriber identity card that contains subscriber information for the second network; and

a control unit to control the first radio frequency unit and the second radio frequency unit to stand by simultaneously, to determine whether the mobile terminal is in a full state to one of the first network and the second network, and to send, when the mobile terminal is in the full state to one of the first network and the second network, a call request to the other network of the first network and the second network that the mobile terminal is not in the full state
