Description

Method for implementing supplementary service and terminal

Technical field

The present invention relates to the field of communications, and in particular, to a method and a terminal for implementing a supplementary service.

Background technique

With the development of communication technology, the existing communication network has gradually developed into an all-Internet protocol IP network with stronger adaptability and more cost. The network operator is implementing the IMS (IP Multimedia Subsystem) network as a common core. Network to provide multimedia services to IMS users over IP networks.

VoLTE (Voice over LTE) is an IMS-based voice service. The supplementary services in the IMS network environment include unconditional call forwarding (CFU), busy call forwarding (CFB), unanswered call forwarding (CFNRy), and call hold. (HOLD), Call Waiting (CW), Multiparty Call (MPTY), etc. With the use of mobile VoLTE terminals, these supplementary services will be more and more used in VoLTE terminals. Under the current mobile specification requirements, the user can save the user's tariff based on the PS channel. When the supplementary service is used, the VoLTE terminal should first query and set the UT interface of the PS domain under the IMS system. After the query and setting is successful, the supplementary service can be used normally.

According to the requirements of the mobile specification, the existing VoLTE terminal may include the following two situations: 1. Inserting a non-VoLTE card; 2. Inserting a VoLTE card but not in a VoLTE network coverage area. For the two scenarios, when the VoLTE terminal needs to use the supplementary service, the following problem occurs: When the VoLTE terminal opens the supplementary service configuration interface and performs service query and activation, the interface often displays “The network is busy, please try again later”. The status of the supplementary service is unusable, and even the interface is stuck, which seriously affects the user experience. The reason is that when the VoLTE terminal uses the supplementary service, it will preferentially query and set through the PS domain UT interface, but the actual conditions of the VoLTE terminal used by the user do not support the two situations as described above, such as trying to go under the IMS system. The PS domain channel will cause the VoLTE terminal to fail to use the supplementary service normally.

In summary, how to improve the success rate of using the supplementary service in the above two situations by the VoLTE terminal is a technical problem to be solved by those skilled in the art.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present invention and the above figures are used to distinguish similar objects without having to use To describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. This In addition, the terms "comprises" and "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

In the embodiment of the present invention, it is assumed that the IMS service status may correspond to the first threshold and the second threshold respectively, and the IMS service status corresponding to the first threshold may enable the user to use the supplementary service normally in the PS domain, and the IMS service status corresponding to the second threshold may be The user normally uses the supplementary service in the CS domain.

Under the corresponding conditions, the PS domain and the CS domain can provide corresponding PS channels and CS channels to users under the coverage of the communication network, so that the user can normally use the supplementary service through the PS channel or the CS channel, because the PS domain is responsible for the user's data. The CS domain is responsible for the user's voice service. In order to improve the user experience, the PS domain and the CS domain are usually distributed in the same physical area. For example, the PS domain is distributed in the A area, and the CS domain is distributed, so that the user can The A area uses the PS domain and the CS domain for wireless communication services.

In the existing solution, after the terminal initiates the supplementary service request message, the terminal preferentially queries and sets the UT interface of the PS domain in the A-zone IMS system. After the query is successfully set, the supplementary service can be used normally. However, if the current communication network does not support the IMS service or the terminal does not support the IMS service capability, the terminal will not be able to use the supplementary service normally in the PS domain, and will not attempt to perform supplementary services in the CS domain, resulting in failure to use the supplementary service.

In the embodiment of the present invention, when the terminal initiates the supplementary service request message, the terminal may perform the supplementary service because the terminal has the CS domain, so the terminal can be executed in the CS domain in the case that the PS domain cannot perform supplementary services. After the supplementary service request message is initiated, the current IMS service status may be queried, and the supplementary service is performed in the PS domain or the CS domain according to the threshold corresponding to the IMS service status that is queried, that is, the first threshold corresponds to the PS domain, and the second threshold is used. Corresponding to the CS domain, which improves the success rate of supplementary service usage and increases the user experience.

For the sake of understanding, the specific process in the embodiment of the present invention is described below. Referring to FIG. 1, an embodiment of the method for implementing supplementary service in the embodiment of the present invention includes:

101. The terminal initiates a supplementary service request message.

When the terminal needs to use the supplementary service in the communication process, the terminal may initiate a supplementary service request message to the server.

For example, during a call between the A user and the B user, when the C user attempts to establish a call with the user A, the A user can use the call waiting (CW) supplementary service to be notified that the C user calls in, and the A user terminal then A call waiting request message can be initiated to the server.

It can be understood that the terminal in this embodiment is a VoLTE terminal, and the description is not repeated hereafter.

It should be noted that, in an actual application, the terminal in this embodiment may be a smart phone, a tablet computer, or the like, as long as the mobile phone card can be inserted, and the specific type is not limited herein.

102. The terminal queries, according to the supplementary service request message, the current multimedia subsystem IMS service status.

After the terminal initiates the supplementary service request message, the terminal may query the current IMS service status according to the supplementary service request message, where the IMS service status is recorded in the terminal, and may correspond to different thresholds, and the terminal may perform according to different thresholds that are queried. The corresponding operational process.

It should be noted that the IMS service status in this embodiment may correspond to different thresholds, but the terminal only records a threshold corresponding to an IMS service status, which is used to indicate the current IMS service status of the terminal.

103. If the IMS service status corresponds to the first threshold, the terminal performs a supplementary service corresponding to the supplementary service request message by using the packet switched PS domain.

If the terminal queries the IMS service state corresponding to the first threshold, indicating that the current communication network supports the IMS service, and the terminal also supports the IMS service capability, the terminal may perform the supplementary service corresponding to the supplementary service request message through the PS domain in the IMS system, that is, through the PS. The UT interface of the domain is queried and configured. After the query is successfully configured, the supplementary service can be used normally.

For example, if the current communication network supports the IMS service and the terminal also supports the IMS service capability, the terminal may record the current IMS service status as a first threshold, such as 1, the first threshold has a corresponding relationship with the PS domain, that is, if the terminal Querying the IMS service status record to 1, means that the terminal can perform supplementary services through the PS domain. It can be understood that, in practical applications, the first threshold may be a value other than 1, and the embodiment is merely an example.

104. If the IMS service status corresponds to the second threshold, the terminal performs a supplementary service corresponding to the supplementary service request message by using the circuit switched CS domain.

If the terminal queries that the IMS service status corresponds to the second threshold, indicating that the current communication network does not support the IMS service or the terminal does not support the IMS service capability, or both of the situations exist simultaneously, the terminal The supplementary service corresponding to the supplementary service request message cannot be performed by the PS domain in the IMS system, and the terminal can perform the supplementary service corresponding to the supplementary service request message through the circuit switched CS domain, that is, the terminal performs query and configuration through the normal network CS domain channel, and queries the configuration. After successful, the supplementary service can be used normally.

For example, if the current communication network does not support the IMS service or the terminal does not support the IMS service capability, or both of the conditions exist, the terminal may record the current IMS service status as a second threshold, such as 0, the second threshold. Corresponding to the CS domain, that is, if the terminal queries the IMS service status record to 0, it means that the terminal needs to perform supplementary service through the CS domain. It can be understood that, in practical applications, the second threshold may be a value other than 0, as long as it is different from the first threshold, the embodiment is merely an example.

It should be noted that the terminal does not support the IMS service capability, which may be due to the use of the non-VoLTE mobile phone card. For example, the SIM card that does not support VoLTE may be used in other applications, and the terminal may not support the IMS service capability. No restrictions are imposed.

It can be understood that the step 104 in this embodiment is not executed after step 103.

Steps

103 and 104 are two methods for performing supplementary service according to the query result of step 102, and step 103 and step 104 are parallel relationships. , not the order in which the terminals are executed.

In this embodiment, by querying the current IMS service status, the terminal can use the PS domain or the CS domain to perform supplementary services according to whether the communication network supports the IMS service and whether the terminal supports the IMS service capability, thereby effectively avoiding the existing In the technology, the PS domain is not supported due to the actual situation, which causes the terminal to fail to use the supplementary service normally, which improves the success rate of the supplementary service.

It should be noted that the IMS service status of the foregoing terminal may be implemented through different paths, which are respectively described below:

Referring to FIG. 2, another embodiment of an implementation method of a supplementary service in an embodiment of the present invention includes:

Step 201 in this embodiment is the same as step 101 in the embodiment shown in FIG. 1, and details are not described herein again.

202, the terminal determines whether the current communication network supports the IMS service, if not, step 203 is performed, and if so, step 204 is performed;

After the terminal initiates the supplementary service request message, the terminal may determine whether the current communication network supports the IMS service.

In this embodiment, the specific manner in which the terminal determines whether the current communication network supports the IMS service may be think:

and / or,

It can be understood that, in an actual application, when the user turns on the device, the terminal initiates an registration request to the PS domain of the communication network, and the network approves the request of the mobile phone to send an attach accept message, in the message. Contains whether the network supports IMS services. In addition, when the user moves from one location area to another, the message that the communication network succeeds by the TAU Tracking area update also includes whether the communication network of the current area supports the IMS service. Therefore, the terminal can record whether the communication network of the current area supports the IMS service by querying the registration acceptance message and the location area update message, thereby determining whether the current communication network supports the IMS service.

It should be noted that the foregoing only describes the specific manner in which the terminal determines whether the current communication network supports the IMS service by using two examples. In an actual application, the terminal may also use other judgment methods to combine or use the same, as long as the current determination can be determined. Whether the communication network supports the IMS service, the specific judgment method is not limited herein.

203. The terminal records the IMS service status as a second threshold.

If the current communication network does not support the IMS service, the terminal may record the local IMS service status as a second threshold.

Specifically, the second threshold in this embodiment may be set by the terminal, and the second threshold indicates that the terminal cannot perform supplementary service through the PS domain, and the specific setting manner is not limited herein.

The terminal detects whether there is an IMS registration status message sent by the communication network, and the IMS registration status in the IMS registration status information is a third threshold. If not, step 203 is performed, and if yes, step 205 is performed;

If the current communication network supports the IMS service, the terminal may further detect whether there is IMS registration status information delivered by the communication network, and the IMS registration status in the IMS registration status information is a third threshold, if the IMS registration status information IMS registration status is The third threshold indicates that the terminal supports IMS. Service capabilities.

Specifically, in an actual application, after the user turns on the terminal, after the initial PS channel configuration request, the communication network may send an IMS registration status message, such as IMS Registration status=1 or IMS Registration status=0. The IMS registration status message, where the IMS registration status=1, that is, the IMS registration status is the third threshold, indicating that the terminal supports the IMS capability, and the IMS registration status=0, that is, the IMS registration status is the fourth threshold. Of course, the communication network may not send any The IMS registration status message, both of which indicate that the terminal does not support the IMS capability, the terminal can record whether the IMS capability is supported by the threshold corresponding to the IMS Registration status. It should be noted that the threshold corresponding to the IMS Registration status may be other than 0 and 1, and the embodiment is merely an example.

It can be understood that, based on the above-described example, in this embodiment, if the terminal detects that there is no IMS registration status message sent by the communication network, the communication network does not deliver the IMS registration status to the third threshold or the IMS registration status is the first. The IMS registration status message of the four thresholds, or the IMS registration status message that the IMS registration status is the fourth threshold, but the terminal does not detect that the IMS registration status is the third threshold IMS registration status message, and the terminal does not The IMS service capability is supported. Then, in both cases, the terminal may perform step 203 to record the IMS service status as a second threshold.

205. The terminal records the IMS service status as a first threshold.

If the terminal detects that the IMS registration status message is sent by the communication network and the IMS registration status in the IMS registration status information is the third threshold, that is, the IMS registration status=1 sent by the communication network indicates that the terminal supports the IMS service capability. Then, in the case that the current communication network supports the IMS service, the terminal can record the IMS service status as the first threshold.

It should be noted that the first threshold in this embodiment may also be set by the terminal, and the second threshold indicates that the terminal can perform supplementary service through the PS domain. In actual applications, as long as the first threshold and the foregoing description The two thresholds can be distinguished. The specific setting method is not limited here.

It is to be understood that the step 202 to the step 205 in this embodiment may be performed before the step 201, as long as the terminal can record the current IMS service status before the step 206, which is not limited herein. In addition, if the terminal IMS service status is recorded as the second threshold, that is, step 203 in this embodiment, which means that the terminal cannot perform supplementary service using the PS domain, the terminal may directly follow step 203. Step 206 is performed.

Steps 206 to 208 in this embodiment are the same as steps 102 to 104 in the embodiment shown in FIG. 1, and details are not described herein again.

In this embodiment, before the terminal queries the current IMS service status, it may first determine whether the communication network supports the IMS service, and then determine whether the terminal supports the IMS service capability by detecting whether the IMS registration status message is sent by the communication network, and according to In these two cases, the IMS service status is actually recorded, so that the terminal can use the CS domain to perform supplementary services if the VoLTE network does not cover the area where the terminal is located or uses a non-VoLTE card, instead of preferentially using the PS domain to cause the supplementary service to fail. The success rate of supplementary business use is greatly improved, and the user experience is also improved.

Referring to FIG. 3, another embodiment of an implementation method of a supplementary service in an embodiment of the present invention includes:

Step 301 in this embodiment is the same as step 101 in the embodiment shown in FIG. 1, and details are not described herein again.

The terminal detects whether there is an IMS registration status message sent by the communication network, and the IMS registration status in the IMS registration status information is a third threshold. If not, step 303 is performed, and if yes, step 304 is performed;

Based on the part of the description in the step 204 of the embodiment shown in FIG. 2, after the terminal initiates the supplementary service request message, the terminal may detect whether there is an IMS registration status message delivered by the communication network, and the IMS registration status in the IMS registration status information is The third threshold.

Step 303 in this embodiment is the same as step 203 in the embodiment shown in FIG. 2, and details are not described herein again.

304, the terminal determines whether the communication network supports the IMS service, if not, step 303 is performed, and if so, step 305 is performed;

Based on the part of the description in the step 202 of the embodiment shown in FIG. 2, if the terminal detects the IMS registration status information sent by the communication network, and the IMS registration status in the IMS registration status information is the third threshold, the communication is assumed. The IMS Registration status=1 sent by the network indicates that the terminal supports the IMS service capability, and the terminal can further determine whether the current communication network supports the IMS service.

Step 305 in this embodiment is the same as step 205 in the embodiment shown in FIG. 2, and details are not described herein again.

It can be understood that the step 302 to the step 305 in this embodiment may be performed before the step 301, as long as the terminal can record the current IMS service status before the step 306, which is not limited herein. In addition, if the terminal IMS service status is recorded as the second threshold, that is, step 303 in this embodiment, which means that the terminal cannot perform supplementary service using the PS domain, the terminal may directly perform step 306 after step 303.

Steps 306 to 308 in this embodiment are the same as steps 102 to 104 in the embodiment shown in FIG. 1, and details are not described herein again.

In this embodiment, before the terminal queries the current IMS service status, it first determines whether the terminal supports the IMS service capability by detecting whether the IMS registration status message is sent by the communication network, and then determines whether the communication network supports the IMS service, and according to In these two cases, the IMS service status is actually recorded, so that the terminal can use the CS domain to perform supplementary services if the VoLTE network does not cover the area where the terminal is located or uses a non-VoLTE card, instead of preferentially using the PS domain to cause the supplementary service to fail. The success rate of supplementary business use is greatly improved, and the user experience is also improved.

It should be noted that, in the embodiment shown in FIG. 2 and the embodiment shown in FIG. 3, the terminal determines whether the communication network supports the IMS service and the terminal detects whether there is an IMS registration status message that the IMS registration status delivered by the communication network is the third threshold. The two steps are performed in sequence, and it can be understood that, in practical applications, based on the embodiment illustrated in FIG. 2 and the embodiment illustrated in FIG. 3, the two steps described above may also be performed simultaneously. However, the terminal records the IMS service status as the first threshold only when the communication network supports the IMS service capability and the terminal detects that the IMS registration status sent by the communication network is the third threshold. In other cases, The terminal records the IMS service status as the second threshold. For the other operations, refer to the embodiment shown in FIG. 2 and the embodiment shown in FIG. 3, and details are not described herein again.
