It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The invention is realized based on an IMS emergency call system, which mainly comprises: a terminal, a radio access network and a core network, a proxy call session control function (P-CSCF) entity, and a Public Safety Answering Point (PSAP). The terminal is provided with a first mobile phone card and a second mobile phone card, and the first mobile phone card and the second mobile phone card may be SIM cards or USIM cards.
In the present invention, the first mobile phone card refers to a mobile phone card used by the terminal to make an emergency call, the second mobile phone card refers to another mobile phone card set in the terminal except for the first mobile phone card, and the number of the second mobile phone cards may be one or multiple.
In the present invention, the terminal includes an IMS-based user terminal, such as a mobile phone. Of course, the terminal is not limited to the IMS-based user terminal, and may be other terminals as long as the terminal is compatible with the IMS.
Example 1
The embodiment provides an emergency call method for a multi-card terminal, which is suitable for a terminal, wherein a first mobile phone card and a second mobile phone card are arranged in the terminal. As shown in fig. 2, the method specifically includes the following steps:
and S11, the first mobile phone card and the second mobile phone card are accessed and registered to a wireless access network and a core network, so that the first mobile phone card and the second mobile phone card can send and receive wireless signals through the network.
S12, sending an invite message to the proxy call session control function entity through the first mobile phone card, where the invite message carries the numbers of the first mobile phone card and the second mobile phone card and a target emergency call number, so that the proxy call session control function entity forwards the invite message to a public safety answering point.
In china, the target emergency call numbers include, but are not limited to, 110, 120, 112, and 119. Including but not limited to 911 in the united states. In this embodiment, the target emergency call number is taken as 110 for example to describe, and when the target emergency call number is another number, the processing procedure is the same as that of 110, which is not described herein again.
For example, when the user dials 110 through the first handset card, the terminal sends an invite message to the proxy call session control function entity through the first handset card. Different from the prior art, the invite message sent by the terminal not only carries the number of the first handset card and the target emergency call number (i.e. 110), but also adds the number of the second handset card. After receiving the invite message, the proxy call session control function entity forwards the invite message to the public safety answering point. And after receiving the invite message, the public safety answering point stores the numbers of the first mobile phone card and the second mobile phone card for callback when needed. When the emergency call is interrupted due to network reasons or signal reasons, and the public safety answering point needs to know more information and call back, the number of the first mobile phone card can be called back directly, if the call back of the number of the first mobile phone card fails, the number of the second mobile phone card can be called back continuously due to the fact that the invite message carries the number of the second mobile phone card, and the success rate of the emergency call back is improved. Of course, the number of the second handset card may be called back first, and if the number of the second handset card fails to be called back, the number of the first handset card is called back continuously, and the calling sequence of the first handset card and the second handset card is not limited in any way in this embodiment.

In this embodiment, the target emergency call number is taken as 110 for example to describe, and when the target emergency call number is another number, the processing procedure is the same as that of 110, which is not described herein again.
For example, when the user dials 110 through the first handset card, the terminal sends an invite message to the proxy call session control function entity through the first handset card. Different from the prior art, the invite message sent by the terminal not only carries the number of the first handset card and the target emergency call number (i.e. 110), but also adds the number of the second handset card. After receiving the invite message, the proxy call session control function entity forwards the invite message to the public safety answering point. And after receiving the invite message, the public safety answering point stores the numbers of the first mobile phone card and the second mobile phone card for callback when needed. When the emergency call is interrupted due to network reasons or signal reasons, and the public safety answering point needs to know more information and call back, the number of the first mobile phone card can be called back directly, if the call back of the number of the first mobile phone card fails, the number of the second mobile phone card can be called back continuously due to the fact that the invite message carries the number of the second mobile phone card, and the success rate of the emergency call back is improved.
