Detailed ways

In the existing technology, for dual-card dual-standby smart terminals, the following scenario may exist: the service cell where one subscriber identity card currently resides supports the emergency call function, and the service cell where the other subscriber identity card currently resides does not support the emergency call function. Call function. When there is an emergency call request, the subscriber identity card that performs the emergency call process is usually determined according to a preset priority.

For example, the priority of subscriber identity card 1 is preset to be higher than subscriber identity card 2. When there is an emergency call request, subscriber identity card 1 is used first to execute the emergency call process. However, the serving cell where the subscriber identity card 1 currently resides may not support the emergency call function. this When the network is found, the terminal device needs to fall back to other domains to perform network search operations. After discovering the network, it initiates an emergency bearer establishment request, registration, and finally initiates an emergency call process.

It can be seen that if the serving cell where the high-priority subscriber identity card currently resides does not support the emergency call function, it will take a long time to initiate the emergency call process and the efficiency will be low.

In the embodiment of the present invention, since the serving cell where the target subscriber identity card currently resides supports the emergency call service, the target subscriber identity card can directly perform the emergency call process, reducing the time required to initiate the emergency call process and improving the efficiency of the emergency call process. efficiency.

For example, the chip system may include a chip, and may also include other discrete devices.

In some embodiments, the network device may also communicate with the Internet Protocol (Internet Protocol) Protocol, IP) network for communication, such as the Internet, a private IP network, or other data networks.

In the embodiment of the present invention, the emergency call method corresponding to the following steps 101 to 103 can be executed by a chip with data processing capabilities (such as a baseband chip) in the terminal device, or by the terminal device including the above-mentioned chip with data processing capabilities. The chip is executed by the chip module.

Step 101: Receive an emergency call request.

In a specific implementation, when the terminal device is in a non-network state, or when the terminal device is in an arrears state, the user can use the terminal device to dial an alarm or distress call such as 110, 119, 120, etc.

In specific implementation, the terminal device can be a multi-card multi-standby terminal device, supporting multiple subscriber identification cards. Multiple user identification cards can work at the same time or in a time-sharing manner. For example, the terminal equipment is a dual-SIM dual-standby dual-pass terminal equipment, a three-SIM three-standby terminal equipment, etc.

Taking the terminal device as a dual-SIM dual-standby dual-pass terminal device as an example, two user identification cards can be inserted into the terminal device. The two user identification cards support two different network modes and can work at the same time. Specifically, the structure, working principle, and working process of the multi-SIM multi-standby terminal device can refer to existing products, and the embodiments of the present invention will not be described in detail here.

Before performing step 101, multiple subscriber identification cards of the terminal device can all normally reside on the network. Continuing to take the terminal device as a dual-SIM dual-standby dual-pass terminal device as an example, the operator of subscriber identity card 1 is China Mobile and resides in the 4G network; the operator of subscriber identity card 2 is China Unicom and resides in the 5G network.

Step 102: Determine the target subscriber identity card for performing the emergency call.

After receiving the emergency call request, it is necessary to determine which subscriber identity card to use to initiate the emergency call process. The identity card used to initiate the emergency call process is the target subscriber identity card. Since the terminal device is a multi-card, multi-standby terminal device, it is necessary to select one user identification card from multiple user identification cards as the target user identification card.

In this embodiment of the present invention, it is possible to obtain whether the serving cell where each subscriber identity card currently resides supports the emergency call service. If the serving cell where a certain subscriber identity card currently resides supports the emergency call service, and the serving cell where other subscriber identity cards currently reside does not support the emergency call service, the subscriber identity card in the corresponding serving cell that supports the emergency call service can be determined as the target. User identification card.

For example, the terminal device is a dual-SIM dual-standby terminal device. Subscriber identity card 1 currently resides in serving cell 1, and subscriber identity card 2 currently resides in serving cell 2. Serving cell 1 supports emergency call services, and serving cell 2 does not support emergency calls. Call for service.

When receiving the emergency call request, since the serving cell 1 supports the emergency call service, the subscriber identity card 1 is determined to be the target subscriber identity card.

If the serving cell where all subscriber identity cards currently reside supports the emergency call service, one of the subscriber identity cards can be selected as the target subscriber identity card according to the preset priority. The preset priority can be set according to the personal preferences of the user using the terminal device.

For example, the terminal device is a dual-SIM dual-standby terminal device. Subscriber identity card 1 currently resides in serving cell 1, and subscriber identity card 2 currently resides in serving cell 2. Both serving cell 1 and serving cell 2 support emergency call services. The user sets the priority of subscriber identity card 1 to be higher than the priority of subscriber identity card 2, then subscriber identity card 1 is determined to be the target subscriber identity card.

If the serving cell where some subscriber identity cards currently reside supports the emergency call service, and there are multiple subscriber identity cards, one of the above partial subscriber identity cards can be selected as the target subscriber identity card according to the preset priority.

For example, the terminal device is a three-card three-standby terminal device, user identification card 1 currently resides in service cell 1, user identification card 2 currently resides in service cell 2, and user identification card 3 currently resides in service cell 3. Service cell 1 and service cell 2 both support emergency call service, but service cell 3 does not support emergency call service. If the user sets the priority of user identification card 1 to be higher than the priority of user identification card 2, user identification card 1 is determined to be the target user identification card.

In this embodiment of the present invention, different target subscriber identification cards may reside in different services. service community. Different target subscriber identification cards can be SIM cards issued by different operators. The SIM card can be a physical SIM card, a USIM card, a virtual SIM card or a cloud SIM card.

In a specific implementation, when the subscriber identity card is camped in the serving cell, the network device can carry indication information in the register accept to indicate whether the serving cell supports the emergency call service. If the indication information indicates EMC=1, it indicates that the serving cell supports the emergency call service; conversely, if the indication information indicates EMC=0, it indicates that the serving cell does not support the emergency call service.

Step 103: Initiate an emergency call process based on the target subscriber identification card.

In a specific implementation, after determining the target user identity card, the terminal device can use the target user identity card to initiate an emergency bearer establishment request and registration in the serving cell where the target user identity card currently resides, and initiate an emergency call.

Specifically, the specific process of the terminal device initiating the emergency call process based on the target subscriber identity card can refer to the existing protocol. The embodiment of the present invention can use the emergency call process specified in the existing protocol to initiate the emergency call.

In a specific implementation, if there is no emergency call request but an ordinary call request, the user identification card with the highest priority can be selected to perform the corresponding call process according to the user's preset priority.

For example, the user sets the priority of subscriber identity card 1 to be higher than the priority of subscriber identity card 2 in advance. When there is a general call request, the terminal device initiates the call process with subscriber identity card 1.

In specific implementation, if the serving cell where the subscriber identity card currently resides does not support emergency call services, the terminal device needs to fall back to other domains to select emergency services, perform network searches and other operations in other domains, and then initiate an emergency bearer establishment request and registration. , and then initiate an emergency call.

If the serving cell where the subscriber identity card currently resides supports the emergency call service, the terminal device can directly initiate an emergency bearer establishment request and registration in the serving cell where the subscriber identity card currently resides, and then initiate an emergency call.

It is set that the service cell 1 where the subscriber identity card 1 currently resides supports the emergency call service, and the service cell 2 where the subscriber identity card 2 currently resides does not support the emergency call service. Then the process of the emergency call performed by the subscriber identity card 1 is the same as that of the subscriber identity card. 2, it can be seen that the process of initiating emergency calls by subscriber identity card 1 is greatly simplified, so the speed and efficiency of initiating emergency calls can be improved.

Therefore, in this embodiment of the present invention, after receiving an emergency call request, the subscriber identity card supporting the emergency call service in the currently resident serving cell is used as the target subscriber identity card, which can effectively improve the speed and efficiency of initiating emergency calls.

Taking the terminal device as a dual-SIM dual-standby terminal device as an example, the emergency call method provided in the above embodiments of the present invention will be described below.

Referring to Figure 2, a flow chart of another emergency call method in an embodiment of the present invention is provided.

Step 201: Two subscriber identity cards reside in different serving cells.

In a specific implementation, user identification card 1 resides in service cell 1, and service cell 1 supports 4G network; user identification card 2 resides in service cell 2, and service cell 2 supports 5G network.

Step 202: Receive an emergency call request.

Step 203: Determine whether the following preset conditions are met: the EMC of the serving cell where one subscriber identity card currently resides is 1, and the EMC of the serving cell where the other subscriber identity card currently resides is 0.

If the preset condition is met, step 204 is executed; otherwise, if the preset condition is not met, step 206 is executed.

In the embodiment of the present invention, failure to meet the preset conditions means that the serving cells where the two subscriber identity cards currently reside support the emergency call service, or neither of them supports the emergency call service.

For example, when the user identification card 1 resides in the service cell 1, the network device sends a registration Indication information is obtained during reception, and the indication information indicates that EMC=1. When the subscriber identity card 2 resides in the serving cell 2, the indication information is obtained during registration reception sent from the network device, and the indication information indicates that EMC=0.

Thus, it is determined that the preset conditions are met.

For another example, when the subscriber identity card 1 is camping in the serving cell 1, it obtains indication information from the registration reception issued by the network device, and the indication information indicates EMC=1. When the subscriber identity card 2 is camped in the serving cell 2, it obtains indication information from the registration reception issued by the network device, and the indication information indicates EMC=1.

Therefore, it is determined that the preset conditions are not met.

Step 204: determine the target subscriber identity card.

For example, when the subscriber identity card 1 is camping in the serving cell 1, it obtains indication information from the registration reception issued by the network device, and the indication information indicates EMC=1. When the subscriber identity card 2 is stationed in the serving cell 2, it obtains indication information from the registration reception issued by the network device, and the indication information indicates EMC=0.

Since the serving cell 1 supports the emergency call service, the target subscriber identity card is determined to be the subscriber identity card 1.

Step 205: Initiate an emergency call process based on the target subscriber identity card.

In this embodiment of the present invention, the specific execution process of the above-mentioned step 205 can refer to the existing technology, and will not be described again here.

Step 206: Select the corresponding subscriber identification card to execute the emergency call process according to the preset priority.

In the embodiment of the present invention, the user sets the priority of subscriber identity card 2 to be higher than subscriber identity card 1, so the terminal device executes the emergency call process based on subscriber identity card 2.

Specifically, depending on whether the serving cell 2 supports the emergency call service, the corresponding emergency call process is executed based on the subscriber identity card 2 .

For example, if serving cell 2 does not support emergency call services, the terminal device needs to fall back to other domains to select emergency services, perform network search and other operations in other domains, and then initiate an emergency bearer establishment request and registration based on subscriber identity card 2, and then initiate Emergency call number.

If serving cell 2 supports emergency call service, the terminal device can directly initiate an emergency bearer establishment request and registration in serving cell 2, and then initiate an emergency call.
