Detailed Description

The following detailed description of specific embodiments of the present application refers to the accompanying drawings. It should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The voice mailbox service can support traditional interactive voice response (Interactive Voice Response, IVR) and can seamlessly interface with a traditional IVR voice platform through a website and/or a client; the voice technology with high recognition rate and the special text double-display technology are adopted, so that the use experience of a user can be improved. In addition, the user can flexibly set a personalized telephone prompt tone, and polite refuses any unwanted telephone; the call transfer is easily set, and any incoming call is not missed. When a user uses a client on a terminal, an account number is not required to be registered; but the user needs to register an account number when logging in the website.

In the voice mail service, at least one visual way of Web pages, clients and multimedia message forwarding is provided for users through visual processing, and information sent by opposite-end equipment is obtained. Through the visual processing of the voice box service, the user operation is more convenient, the use experience of the user is improved, and the method has wide commercial value.

When the client on the terminal is in an offline state (for example, when the terminal is in an offline state), the message in the voice mail service is sent to the terminal (for example, a smart phone used by a user) in a short message mode, and the message is synchronized to an IVR voice platform and a website of the user. The user can view the message in two different ways as described above. And, the application software corresponding to the voice mail business can be downloaded freely. The data flow rate fee generated by the terminal using the voice box service is charged by the operator server; the communication fee generated by using the voice mail is the same as the communication fee directly used on the terminal, and the member of the voice mail service can pay the communication fee by adopting the monthly subscription system.

However, when the terminal is in the international roaming state, if the terminal fails (for example, some software installed in the terminal fails such as conflict or software crash, etc.), the voice mail client on the terminal frequently sends out-of-band short messages to the server; the out-of-band short message is invisible to the terminal, and the server needs to repeatedly process a large number of out-of-band short messages sent by the terminal, so that the data processing pressure of the server is increased; meanwhile, the terminal frequently sends out-of-band short messages to the server, so that the short message cost of the terminal is increased; particularly, if the terminal is in the international roaming state, a large amount of international roaming short message cost is generated by the terminal, and the use experience of the user is reduced.

Fig. 1 shows a flow chart of an information interaction method provided in an embodiment of the present application. The method can be applied to a network side functional entity which is in communication connection with the terminal.

As shown in fig. 1, the information interaction method includes, but is not limited to, the following steps.

Step S101, the identification of the terminal and the information interaction identification are obtained.

The information interaction identification is an identification which is determined based on the network state of the terminal and used for representing whether the terminal needs to send uplink short messages to the network side functional entity.

For example, the uplink short message is used for inquiring the subscription status of the preset service corresponding to the terminal.

By acquiring the identification of the terminal and the information interaction identification which can represent whether the terminal needs to send the uplink short message to the network side functional entity, the information interaction mode of the terminal can be clarified, and the information interaction efficiency with the terminal is improved.

Step S102, determining whether the terminal subscribes to a preset service according to the identification of the terminal.

It should be noted that, when the terminal subscribes to a service, the network side functional entity will record service information correspondingly. For example, when the terminal subscribes to a preset service (e.g., a voice message service, etc.), the network side function entity binds the identifier of the terminal with the identifier of the service to which the terminal subscribes successfully, so as to facilitate subsequent information query.

Therefore, the network side functional entity can query and obtain the related information of the service subscribed by the terminal successfully by taking the identification of the terminal as a query index, and the terminal can acquire the information of the subscribed service conveniently.

Step S103, under the condition that the terminal is subscribed to the preset service, the terminal is interacted with the information according to the information interaction identifier, so that the terminal obtains service data corresponding to the preset service.

The information interaction identifier may include identifiers corresponding to different information interaction modes. For example, interaction in the form of short messages, interaction in the form of data channels in a mobile network, interaction in the form of voice communications, etc.

By adopting the information interaction identification, the network side functional entity can quickly determine the information interaction mode between the network side functional entity and the terminal, and the communication efficiency is improved.

In this embodiment, by acquiring the identifier of the terminal and the information interaction identifier, the information interaction identifier is determined based on the network state where the terminal is located, and whether the terminal needs to send uplink short messages to the network side functional entity can be represented by the information interaction identifier; determining whether the terminal subscribes to a preset service according to the identification of the terminal, and further determining whether a service corresponding to the preset service needs to be provided for the terminal; under the condition that the terminal is subscribed to the preset service, carrying out information interaction with the terminal according to the information interaction identifier so as to enable the terminal to acquire service data corresponding to the preset service, so that the interaction times of out-of-band short messages between the terminal and the network side equipment can be reduced, unnecessary roaming short message cost possibly generated by the terminal can be saved, and the use experience of a user can be improved; meanwhile, the data processing capacity of the network side functional entity can be reduced, and the communication efficiency is improved.

Fig. 2 shows a flow chart of an information interaction method provided in an embodiment of the present application. The method can be applied to a network side functional entity which is in communication connection with the terminal.

As shown in fig. 2, the information interaction method includes, but is not limited to, the following steps.

Step S201, the identification of the terminal and the information interaction identification are obtained.

The information interaction identifier is used for representing that the terminal can interact with the network side functional entity in a mode of a data channel in the mobile network or in a mode of voice communication.

Step S202, generating a query request according to the identification of the terminal.

Wherein the query request includes not only an identification of the terminal (e.g., an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI) installed in the terminal, etc.); and may also include identification of different services for which the terminal requests a query (e.g., identification of visual voicemail (Visual Voice Mail, VVM) services, identification of voice services, etc.), etc.

Through the query request, the query requirements in the characterization can be represented, the network side functional entity can correspondingly query different services based on different requirements of the terminal, the query accuracy is improved, the corresponding response to the query request of the terminal is more targeted, and the information interaction efficiency is improved.

Step S203, a query request is sent to a unified data warehouse function UDR entity.

Wherein the unified data warehouse function (Unified Data Repository, UDR) entity is for storing communication data, which may comprise shared data and/or user data. Other devices in the network can learn the data needed by the devices through the UDR entity.

For example, a unified data management function (Unified Data Management, UDM) entity in the network side functional entity may access the UDR entity, and retrieve data stored in the UDR entity based on user data (e.g., an identifier of a terminal, etc.), to obtain service subscription data corresponding to the user data, etc., so as to facilitate processing a service used by a user.

As another example, a policy control function (Policy Control Function, PCF) entity in the network side functional entity can obtain policy data (e.g., authentication policy and authentication parameters information for the terminal) required by the entity by retrieving data in the UDR entity.

Step S204, responding to the inquiry response fed back by the UDR entity, and determining that the terminal has subscribed to the preset service.

Wherein the query response includes a subscription identification of the preset service.

Through the inquiry response fed back by the UDR entity, service subscription state information corresponding to the identification of the terminal and the subscription identification of the terminal for the preset service can be inquired and obtained, which services the terminal subscribes to and whether subscription data corresponding to the subscribed services are changed or not can be clarified, the subsequent processing of the services subscribed by the terminal is facilitated, and the service processing efficiency is improved.

Step S205, under the condition that the terminal is subscribed to the preset service, the terminal is interacted with the information according to the information interaction identifier, so that the terminal obtains the service data corresponding to the preset service.

It should be noted that, step S205 in the present embodiment is the same as step S103 in the previous embodiment, and will not be described herein.

In this embodiment, by sending a query request to the UDR entity, service information specifically subscribed by the terminal can be quickly obtained, thereby improving the processing efficiency of the service used by the terminal. And when the terminal is in a roaming state and the terminal is determined to be subscribed to the preset service, the terminal interacts with the network side functional entity in a data channel mode or a voice communication mode in the mobile network, so that the interaction times of out-of-band short messages between the terminal and the network side functional entity can be reduced, unnecessary roaming short message cost is saved for a user, the data processing capacity of network side equipment can be reduced, and the communication efficiency is improved.

In some implementations, the query response further includes: presetting state information of a service; information interaction identification includes: the first type of interaction is identified.

In step S103 or step S205, when determining that the terminal has subscribed to the preset service, the terminal performs information interaction with the terminal according to the information interaction identifier, so that the terminal obtains service data corresponding to the preset service, which may also be implemented in the following manner.

And under the condition that the terminal is subscribed to the preset service and the state information of the preset service is not changed, carrying out information interaction with the terminal according to the acquired first type interaction identifier and the network channel so as to enable the terminal to acquire service data corresponding to the preset service.

The first type of interaction identifier is used for indicating that a preset client on the terminal does not send uplink short messages to the network side functional entity. The uplink short message may be information for reporting a state of the terminal. For example, the status short message includes: the service subscription queries status information and/or service data. The service data are data when the terminal and the network side functional entity perform service interaction.

For example, the uplink short message may also be information for querying the change condition of the service subscribed by the terminal, so that the terminal can conveniently learn the real-time status of different subscribed services.

The first type interaction identification is adopted to indicate that the preset client on the terminal does not send the uplink short message to the network side functional entity, so that the interaction times of the short message between the terminal and the network side functional entity can be reduced, and unnecessary communication cost is reduced; and when the terminal fails, the client of the voice mail service can not frequently send the uplink international roaming short message any more, so that the data processing amount of the network side equipment is reduced, and the communication efficiency is improved.

The voice mail service can support traditional interactive voice response (Interactive Voice Response, IVR), and the traditional IVR voice platform is seamlessly docked through a website and/or a client; the voice technology with high recognition rate and the special text double-display technology are adopted, so that the use experience of a user can be improved.

The video flow service is used for enabling the user to obtain the service of network flow of video data aiming at specific applications, so that the user can obtain data flow in a specific direction when watching video online, the use of conventional data flow of the user is reduced, and the use experience of the user is improved.

Aiming at different types of preset services, different services are processed differently, and the processing efficiency of the services is improved.

Fig. 3 shows a flowchart of an information interaction method provided in an embodiment of the present application. The method can be applied to the terminal, and the terminal is in communication connection with the network side functional entity.

As shown in fig. 3, the information interaction method includes, but is not limited to, the following steps.

Step S301, acquiring a network state of the terminal.

Wherein the network state may include: in at least one of a mesh state, an off-network state, a roaming state, and a normal intra-service area communication state.

Note that, in the network state, a state is used to indicate that the terminal does not log off in the communication network, but may be in a state where communication is performed in an area where a network edge or a communication signal is not good.

The current working condition of the terminal can be represented through different network states, so that the terminal can timely propose corresponding communication requirements to the network side functional entity, and the communication service quality of the terminal is improved.

Step S302, generating an information interaction identifier according to the network state.

The information interaction identifier is used for characterizing whether the terminal needs to send an identifier of the uplink short message to the network side functional entity.

For example, when the network state in which the terminal is located is a roaming state, an information interaction identifier for indicating that the terminal does not need to send uplink short messages to the network side functional entity can be generated, so that the short message cost of the terminal can be saved.

For example, when the network state of the terminal is in the normal service area, an information interaction identifier for representing that the terminal can send uplink short messages to the network side functional entity can be generated, and because the terminal is in the normal service area, the cost generated by the short messages sent by the terminal to the network side functional entity can be reduced, the terminal can quickly acquire the needed information under the condition that the terminal does not need to pay, and the information interaction efficiency between the terminal and the network side functional entity is improved.

For example, when the network state of the terminal is in the network state, an information interaction identifier for representing the information interaction mode to be confirmed by the network side functional entity can be generated, so that the terminal obtains the optimal communication information based on the information interaction identifier, the waste condition of the communication cost of the terminal is reduced, and the use efficiency of the user is improved.

Step S303, according to the information interaction identification, the terminal performs information interaction with the network side functional entity so as to obtain service data corresponding to the preset service.

The information interaction identifier can embody an information interaction mode between the terminal and the network side functional entity. For example, interaction in the form of short messages, interaction in the form of data channels in a mobile network, interaction in the form of voice communications, etc.

By adopting different information interaction modes, different treatments can be correspondingly carried out according to the network state of the terminal, the information interaction efficiency between the terminal and the network side functional entity is improved, the terminal can rapidly and accurately acquire service data corresponding to a preset service, the communication cost of the terminal is reduced, and the use experience of a user is improved.

In this embodiment, the network state of the terminal is obtained; the current working condition of the terminal can be represented through different network states, so that the terminal can timely put forward corresponding communication requirements to a network side functional entity, and the communication service quality of the terminal is improved; generating an information interaction identifier according to the network state, wherein the information interaction identifier is used for representing whether the terminal needs to send an identifier of an uplink short message to a network side functional entity or not so as to reduce the communication cost of the terminal; according to the information interaction identification, the information interaction is carried out with the network side functional entity, so that the information interaction efficiency between the terminal and the network side functional entity can be improved, the terminal can rapidly and accurately acquire service data corresponding to a preset service, the communication cost of the terminal is reduced, and the use experience of a user is improved.

In some specific implementations, the acquiring the network state of the terminal in step S301 includes: acquiring preset network information of a user identification card installed by a terminal and network information to be confirmed sent by a network side functional entity received by the terminal; and determining the network state of the terminal according to the preset network information and the network information to be confirmed.

Wherein the subscriber identity card may comprise: global subscriber identity cards (Universal Subscriber Identity Module, USIM), subscriber identity cards (Subscriber Identity Module, SIM), etc.

The preset network information can represent the home location information of the terminal, for example, the identification information of a home operator server of the terminal and the like; the network information to be confirmed can represent the information of the network environment where the terminal is currently located.

By analyzing the preset network information and the network information to be confirmed, whether the terminal communicates within a preset range or not or whether the network environment where the terminal is currently located is safe or not can be determined, so that the network state where the terminal is located is determined, and the confirmation of the information security of the terminal is improved.

In some implementations, presetting network information includes: network information on a preset digit of the user identification card; network information to be confirmed, including: and the network information is the same as the preset digits and is sent by an operator server of the network where the terminal is currently located.

According to the preset network information and the network information to be confirmed, determining the network state of the terminal comprises the following steps: determining that the terminal is in a non-roaming state under the condition that the network information on the preset digits of the user identification card is determined and the network information which is the same as the preset digits and is sent by an operator server of the network where the terminal is currently located is the same; otherwise, determining that the terminal is in a roaming state.

Wherein the predetermined number of bits is a predefined number of data bits. For example, the first 5 bits or the first 6 bits of the information corresponding to the user identification card; the top 5 bits or the top 6 bits of the network information sent by the operator server of the network where the terminal is currently located.

It should be noted that in the process of analyzing the preset network information and the network information to be confirmed, the analysis needs to be performed based on the information on the same preset digits, for example, the first 5 bits in the preset network information are compared with the first 5 bits of the network information to be confirmed. Thereby making it clear whether the operator information is the same or not and thus determining whether the terminal is in a roaming state or a non-roaming state.

By analyzing the information on the specific preset digits, the judgment on the network state of the terminal can be quickened, so that the terminal can acquire the communication service corresponding to the network state, and the service quality is improved.

In some implementations, the network state includes a roaming state and the information interaction identifier includes a first type of interaction identifier.

In step S302, according to the network status, the information interaction identifier is generated, which may be implemented in the following manner: and under the condition that the network state of the terminal is determined to be a roaming state, generating a first type interaction identifier. Correspondingly, in step S303, according to the information interaction identifier, information interaction is performed with the network side functional entity, so that the terminal obtains service data corresponding to the preset service, and the following manner may be adopted: and sending a first type interaction identifier to the preset client side so that the preset client side can interact with the network side functional entity according to the network channel to enable the terminal to acquire service data corresponding to the preset service.

The first type of interaction identifier is used for indicating that a preset client on the terminal does not send uplink short messages to the network side functional entity, and the preset client is a client for executing preset service.

It should be noted that, the preset client does not send the uplink short message to the network side functional entity, and the channel is taken by me through the mode of subscribing the information in advance, so that the change condition of the preset service subscribed by the terminal is obtained, the short message expense can be saved for the terminal, the change information of the preset service subscribed by the terminal can be obtained in time, the efficiency of obtaining new information by the terminal is accelerated, and the communication efficiency between the terminal and the network side functional entity is improved.

Wherein the network state further comprises a non-roaming state; the information interaction identifiers include a second type of interaction identifier. The generating of the information interaction identifier in step S302 according to the network state may also be implemented in the following manner.

Generating a second type of interaction identifier under the condition that the network state in which the terminal is positioned is determined to be a non-roaming state (such as a network state or a communication state in a normal service area); the second type interactive identifier is used for representing that the terminal needs to send uplink short messages to the network side functional entity so as to enable the terminal to acquire service data corresponding to a preset service.

It should be noted that, through the second type of interaction identifier, the terminal is indicated to need to send the uplink short message to the network side functional entity, so that the terminal can actively send the uplink short message to the network side functional entity, so as to query the information of the preset service subscribed by the terminal, and when the information of the preset service is changed, the service data corresponding to the preset service can be timely obtained, so that the service data obtained by the terminal can meet the real-time requirement of the terminal, and the user experience is improved.

Fig. 6 shows a schematic architecture diagram of a visual voice mail system according to an embodiment of the present application. As shown in fig. 6, the visual voice mail system includes the following devices.

A voicemail client 601, an information server 602, and a voicemail server 603.

The voice mailbox client 601 may execute the VVM service, and the voice mailbox client 601 may acquire service subscription information carried in the out-of-band short message by intercepting the out-of-band short message sent by the terminal.

It should be noted that the visual voice mail system is a system built on an existing voice mail (voicemail) system. The existing server-side protocols must meet the definition in the protocol specification for an interactive mail access protocol (Internet Message Access Protocol, IMAP) interface.

The information server 602 may include an interface for related information provided by an operator, among other things. Such as short message service (Short Message Service, SMS) interfaces, and data interaction interfaces implemented based on network channels, etc. Through the SMS interface, the terminal may implement information interaction (e.g., obtaining Out-Of-Band (OOB) data, etc.) between the voicemail client 601 and the voicemail server 603. The voice mail client 601 can reduce the number of short messages sent through the data interaction interface, so as to reduce the short message cost of the terminal.

It should be noted that, through the OOB data connected independently of the IMAP interface, operation maintenance and basic information setting of the user on the account can be realized. For example, the OOB data may include: type 0SMS interface information. To ensure that the SMS interface information is not visible on a conventional handset terminal, a tag protocol identification (Tag Protocol Identifier, TP-PID) in the message header of the Type 0SMS interface information may be set to "ME data download" (e.g., 0x 7D).

The voice mail client 601 may obtain the voice message sent by the voice mail server 603 through the IMAP interface, so that a user can set a prompt tone conveniently, and the user can set information such as personal identification code (Personal Identification Number, PIN) through a user interface on the terminal.

The information server 602 may also report the uplink state information to the voice mailbox server 603 in an out-of-band short message manner.

The voice mailbox client 601 may query its own voice mailbox status through a short message service center service (Short Message Service Center, SMSC) address; the SMSC address is an address provided by the information server 602 for routing all outgoing visual voicemail out-of-band signals.

In some implementations, the operator server predefines the SMSC address for routing the interactive signals of the voice mail service and writes it in a preprogrammed manner to the terminal device using the visual voice mail.

When the Out-Of-Band States in the OOB is Active, it indicates that the visual voicemail system is available.

The voice mail client 601 can reduce the sending frequency and the times of short messages and reduce the short message cost of the terminal by providing a plurality of different interfaces through the information server and carrying out different information processing modes on the voice mail client.

Fig. 7 shows a block diagram of an information interaction system according to an embodiment of the present application. As shown in fig. 7, the information interaction system includes, but is not limited to, the following devices.

A terminal 710, a first operator server 720, a communication gateway 730, a network side function entity 740 corresponding to the second operator, and a unified data warehouse function UDR entity 750.

The network side functional entity 740 is a device belonging to a second operator, where the second operator and the first operator are operators in different areas, and the second operator is an operator corresponding to the home location of the terminal 710. The network side function entity 740 includes: an access and mobility management function (Access and Mobility Management Function, AMF) entity 741 and a unified data management function, UDM, entity 742.

In the process of communicating with other devices (for example, the first operator server 720, the network side functional entity 740 corresponding to the second operator, etc.), the terminal 710 needs to use State information, so that other devices can learn the current State of the terminal 710.

The manner in which the terminal 710 sends the request for inquiring the status information to the network-side function entity 740 may be implemented as follows.

First, when the voice mail client installed in the terminal 710 activates the voice mail service for the first time, an uplink query message needs to be sent, where the uplink query message may include: at least one of status, device model and Type (Type). The Type at this time is 1.

Next, after the user inserts a communication card (e.g., a subscriber identification card (Subscriber Identity Module, SIM), etc.) on the terminal 710, the voice mail client sends an uplink query message, which may include: at least one of status, device model and Type (Type), where Type is 2.

When the terminal is started and registered to a communication network (e.g., a mobile cellular network) through a SIM card, the network side functional entity 740 sends service subscription information subscribed by the terminal 710 to the terminal 710, and a voice mailbox client installed in the terminal 710 determines whether the service subscription information has a related service subscription identifier by searching a cache of the terminal 710.

If, through the service subscription identifier, it is determined that the terminal 710 does not subscribe to the preset service, the terminal 710 may send an uplink query message to the network side functional entity 740, where the uplink query message may include: at least one of status, device model and Type (Type), the Type at this time being 3. If it is determined that the terminal 710 has subscribed to the preset service, the terminal 710 does not transmit the uplink query message any more.

The STATE (STATE) includes: online or offline. In case it is determined that the network-side function entity 740 does not feed back the query response to the terminal 710, the terminal 710 needs to set its own state offline. The server notification (Server Notifications) fed back by the network side function 740 may be characterized by the STATE. In the case of determining that the State information of the preset service subscribed by the terminal 710 changes, the network side function entity 740 may make the terminal 710 learn the change of the State information by sending the State information.

For example, table 1 shows variable names and their corresponding meanings included in STATE information in embodiments of the present application. As shown in table 1, the PLMN therein is capable of characterizing the identity of the PLMN corresponding to the first operator server 720 where the terminal 710 is currently resident.

Table 1 variables included in state information

When the first operator server 720 receives a State message, where "State" is "Active", it characterizes that the terminal 710 has information (e.g., voice message and/or alert tone) updated.

It should be noted that, when the terminal 710 first sends a request for activating the voice mail service to the network side functional entity 740 corresponding to the second operator, the network side functional entity 740 obtains the identifier of the terminal 710; then, the network side function entity 740 activates the voice mail service for the terminal 710 according to the identifier of the terminal 710, generates a voice mail service subscription identifier, and stores the identifier of the terminal 710 and the voice mail service subscription identifier in the UDR entity 750. The voice mail service activating request can be in the form of State information to transfer information.

When the terminal 710 performs international roaming, the terminal 710 may obtain subscription information (e.g., subscription information includes service subscription information, which may pass through) corresponding to a visual voicemail (Visual Voice Mail, VVM) service of the terminal 710 from a network-side functional entity 740 corresponding to a second operator (i.e., a home server of the terminal 710) when the terminal 710 is powered on and registered on a first operator server (e.g., a foreign operator server, etc.). So that the VVM client installed on the terminal 710 may determine, through the service subscription information, not to send the status short message to the network-side functional entity 740 in the form of an out-of-band short message.

Fig. 8 is a schematic flow chart of an operation method of an information interaction system according to an embodiment of the present application. As shown in fig. 8, the method of operating the information interaction system includes, but is not limited to, the following steps.

In step S801, the terminal 710 starts up and searches for a communication network signal to obtain a communication cell search list.

Wherein the communication cell search list may include: the terminal 710 is capable of receiving communication signals of all communication cells and identities corresponding to the respective communication cells.

Step S802, the terminal 710 reads network information on a preset digit (e.g., the first 5 bits, the first 6 bits, etc.) of a subscriber identity card (e.g., USIM, etc.); and comparing the network information on the preset digits with the identifiers corresponding to the communication cells in the communication cell search list, so that the current network state of the terminal can be determined.

The terminal 710 may be equipped with a user identification card and a preset client (not shown). The preset client is a client that performs a preset service (e.g., a voice mail service and/or a video traffic service, etc.).

The identity of the home operator network (e.g., public land mobile network (Public Land Mobile Network, PLMN) information, etc.) to which the terminal 710 corresponds can be clarified by presetting network information on the digits. For example, if the information of the subscriber identity card read is 46001xxxxxxxx or 46009 xxxxxxxx, the identity of the home operator corresponding to the terminal 710 may be determined from "46001" or "46009".

If the identifier corresponding to each communication cell in the communication cell search list includes network information on a preset number, the terminal 710 is characterized as being in a normal communication range; otherwise, if the identifier corresponding to each communication cell in the communication cell search list does not include the network information on the preset number, the terminal 710 is characterized as being in a communication roaming state.

In step S803, the terminal 710 sends the current network state of the terminal 710 to the preset client, so that the preset client generates an information interaction identifier according to the network state after knowing the current network state of the terminal 710.

The information interaction identifier is an identifier for characterizing whether the terminal 710 needs to send an uplink short message to the network side functional entity 740.

For example, the information interaction identifier may be represented by a roaming value (e.g., roaming identifier (roaming) or international roaming identifier (international roaming)) in the uplink state information (state). If the roaming value is 1, it indicates that the terminal 710 is in a roaming state, and the terminal 710 needs to stop sending the uplink short message to the network side functional entity 740;

if the roaming value is 0, it indicates that the terminal 710 is in a normal communication state (or a non-roaming state), at this time, the terminal 710 may send an uplink short message to the network side function entity 740 to query the service condition subscribed by the terminal 710.

In step S804, in case it is determined that the terminal 710 is in the roaming state, the terminal 710 transmits a registration request to the first operator server 720, so that the first operator server 720 forwards the registration request to the AMF entity 741 through the communication gateway 730.

In step S805, the AMF entity 741 sends a Registration request (e.g. a nudm_uecm_registration message) to the UDM entity 742, and obtains the service subscription status information corresponding to the terminal 710 through a nudm_sdm_get instruction.

In step S806, the UDM entity 742 queries the UDR entity 750 for subscription data of the terminal 710 to determine service information subscribed to by the terminal 710.

For example, the subscription data may include: service subscription status information of the terminal 710 and subscription identification of the terminal 710.

In step S807, the UDR entity 750 sends a query response to the UDM entity 742.

For example, the query response includes: subscription identification of the terminal 710; the subscription identity of the terminal 710 may be denoted as "VVM" to determine whether the terminal 710 is subscribed to VVM services. If the VVM is 1, characterizing terminal 710 has subscribed to the VVM service; if the VVM is 0, then the characterizing terminal 710 is not subscribed to the VVM service.

In step S808, the UDM entity 742 forwards the query response to the AMF entity 741.

Wherein the service subscription status information of the terminal 710 and the subscription identification (e.g., VVM service subscription identification, etc.) of the terminal 710 may be obtained through the nudm_sdm_get Response message.

Step S809 needs to be performed in addition to step S808.

In step S809, the AMF entity 741 performs information interaction with the UDM entity 742 to subscribe to the subscription data change notification service.

For example, the AMF entity 741 may subscribe to a change notification service of subscription data with the UDM entity 742 using a nudm_sdm_subscrib message. In the case of determining that the subscribed subscription data includes change information of state information of a preset service (for example, a VVM service, etc.), the AMF entity 741 receives a change notification actively sent by the UDM entity 742.

Step S810, in the case that it is determined that the terminal 710 has subscribed to a preset service (e.g., a VVM service, etc.), and the state information of the preset service has not changed, generating a registration response according to the subscription identifier and the identifier of the terminal 710; and transmits the registration response to the terminal 710.

Wherein the registration response is forwarded through communication gateway 730 and first operator server 720, so that terminal 710 may obtain the registration response, and thus terminal 710 may obtain the service information subscribed to by the terminal.

In step S811, the terminal 710 determines an information interaction manner between the terminal 710 and the network side functional entity 740 corresponding to the second operator based on the subscription identifier in the registration response.

Step S812, based on the information interaction manner determined in step S811, the terminal 710 performs information interaction with the second network side functional entity 740 corresponding to the operator.

For example, in the case that it is determined that the subscription identifier is used to identify that the terminal 710 has subscribed to a preset service (for example, VVM is 1), the terminal 710 does not send a status short message to the network side functional entity 740 in an out-of-band short message interaction manner, and the preset client installed in the terminal 710 performs interaction of service data with the network side functional entity 740 based on a network channel interaction manner, where the service data is data corresponding to the preset service.

For another example, in the case that the subscription identifier is determined to identify that the terminal 710 does not subscribe to the preset service (for example, VVM is 0), the terminal 710 sends the status short message to the network side functional entity 740 in an out-of-band short message interaction manner.

In this embodiment, the network state of the terminal at present can be clarified through the network information on the preset digits of the user identification card installed on the terminal and the identifier of the communication cell searched by the terminal, and the information interaction identifier for representing whether the terminal needs to send the uplink short message to the network side functional entity is generated further based on the network state, so that the communication mode of the terminal can be rapidly determined, and the communication efficiency is improved; when the terminal is determined to be in a roaming state, when the terminal is registered to a roaming operator server (for example, a first operator server), the UDM of the attribution of the terminal sends the subscription information of a preset service (for example, a voice mail service and the like) to the first operator server so that the first operator server forwards the subscription information of the preset service to the terminal; therefore, when the terminal receives the message sent by the operator server (such as the network side equipment corresponding to the second operator) of the attribution place, the status short message can be sent to the network side equipment corresponding to the second operator without an out-of-band short message interaction mode, the interaction times of the out-of-band short message between the terminal and the network side equipment can be reduced, unnecessary roaming short message expense is saved for a user, the problem that the client side of the voice mail service frequently sends the uplink roaming short message when the terminal fails can be avoided, and the data processing amount of the network side equipment can be reduced.
