Embodiment 1

[0052] see Figure 2 to Figure 5 , figure 2 An optional application scenario of the embodiment of the present invention is shown, including a first terminal device and a second terminal device, where the first terminal device communicates with the second terminal device through a mobile switching network. Here, the first terminal device is a communication device with four-card four-standby function. The so-called four-card four-standby means that the first terminal device can insert four calling cards and be on standby at the same time. Among them, the network standard of each phone card can be any one of 2G (GSM), 2.5G (GPRS), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4G+ (LTE+), WiMax, etc. kind. exist figure 2 In the shown implementation, the first terminal device can include four phone card slots, and four phone cards can be inserted at the same time, and the network standards used are 4G, 3G, 2G, and E (that is, EDGE network, which can be regarded as 2.75G) . ...

Embodiment 2

[0068] This embodiment is substantially the same as Embodiment 1, except that in 306, when it is determined that at least one of the other calling cards is in a non-roaming state, sending the phone number corresponding to the at least one calling card to the second terminal device includes:

[0069] Select a calling card as a pending calling card from the other calling cards, and inquire about the roaming situation of the pending calling card;

[0070] When the pending calling card is in a non-roaming state, sending the phone number corresponding to the pending calling card to the second terminal device;

[0071] When the pending calling card is in the roaming state, inquire about the roaming situation of another pending calling card in the other calling cards, and continue to inquire about the roaming situation of the remaining pending calling cards when the other pending calling card is in the roaming state until the inquiry is made There is a pending calling card in a non-r...

Embodiment 3

[0074] read on Figure 2 to Figure 5 , figure 2 An optional application scenario of the embodiment of the present invention is shown, including a first terminal device and a second terminal device, where the first terminal device communicates with the second terminal device through a mobile switching network. Here, the first terminal device is a communication device with four-card four-standby function. The so-called four-card four-standby means that the first terminal device can insert four calling cards and be on standby at the same time.

Abstract

An embodiment of the present invention provides a communication method and a communication system, which are applied to a first terminal device with multiple cards and multiple standbys. Each phone card in the first terminal device corresponds to a phone number. The incoming call processing method includes: when receiving When a call request is received, detect the called number corresponding to the call request; judge whether the calling card corresponding to the called number is in a roaming state, and determine the number of other calling cards when the calling card corresponding to the called number is in a roaming state Roaming status, wherein the roaming status is a roaming state or a non-roaming state; when it is determined that at least one of the other calling cards is in a non-roaming state, sending the phone number corresponding to the at least one calling card to the second terminal device. The invention reduces extra roaming charges generated when the called number is in roaming state.

Description

technical field [0001] The invention relates to communication technology, in particular to a communication method and a communication system. Background technique [0002] At present, more and more mobile communication devices support the dual-card function, which not only facilitates users to support multiple SIM cards, but also facilitates frequent travelers to switch between different SIM cards for call services and save phone charges. However, there is such a situation: the owner's two cards are processed in different regions, which is convenient for business trips in the two places. When he is in place A, if someone calls the card applied for in place B, if he answers the call at this time, both parties may have to generate additional roaming charges. If you hang up at this time, it is impolite on the one hand; on the other hand, the other party does not know the intention of being hung up, and may think that the owner of the phone is busy at this time and gave up call...
