Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and apparatus for information transmission, a storage medium, and a chip. Background Art

[0002] At present, 5G (5th-Generation) networks have been basically commercially available throughout the region, and users generally conduct daily services in a 5G environment. The current 5G networks are mainly divided into two networking forms: SA (Standalone Access) and NSA (Non-Standalone Access). Among them, SA networking, that is, 5G standalone networking, consists of a 5G core network and 5G base stations; NSA networking, that is, non-standalone networking, basically consists of an LTE (Long Term Evolution) core network and 5G base stations, and adopts the LTE-NR dual-connection mode.

[0003] In addition, terminals usually use two modes to send and receive SMS (Short Messaging Service) information in a 5G network: NAS (None Access Stratum) and IMS (IP Multimedia Subsystem). When a terminal supports both of these information sending modes, it can preferentially select the IMS mode to complete the 5G SMS service. When the IMS mode fails, the terminal can use the NAS mode to re-perform the SMS service. Summary of the Invention

[0051] Figure 5 is a block diagram of an information transmission device shown according to an exemplary embodiment. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0052] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] It should be noted that all actions of obtaining signals, information or data in this application are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and obtaining authorization from the corresponding device owner.

[0054] This disclosure is mainly applied to the scenario where the terminal performs SMS services in the SA networking mode of the 5G network. In the related art, when the UE performs SMS services in the SA networking mode of the 5G network, it preferentially selects the IMS mode. If an error code is returned by the network device due to a current network anomaly or a cell failure in the area where the UE is located, the UE will retry the NAS mode to continue the same SMS service to ensure that the user's short message can be successfully sent. When sending SMS information based on the NAS mode, an SMSF (Short Message Service Function) needs to be deployed in the 5G core network to interface with the SMSC (Short Message Service Center).

[0055] However, at present, most 5G SA networks do not fully deploy SMSF network elements. Therefore, the network side does not support the NAS mode. When the UE fails to send SMS information using the IMS mode, retrying the NAS mode according to the original solution will also fail. The final result will be that the user's SMS service cannot be successfully carried out. In the actual application scenario, in the 5G SA network, it is common for the SMS information sent through the IMS to fail due to a sudden temporary network anomaly. If the SMS cannot be sent or received by retrying the NAS method, it will affect the normal progress of the user's SMS service, thereby affecting the user experience.

[0056] To solve the above problems, this disclosure provides an information transmission method, device, storage medium and chip. When the first communication network of the target terminal is a specified communication network (such as a 5G SA network), when the target terminal fails to send SMS information outward, it can be determined whether the first communication network where the target terminal camps supports the non-access stratum NAS information sending mode. If it is determined that the first communication network does not support the NAS information sending mode, the first communication network can be switched to a second communication network (for example, switching the 5G SA network of the target terminal to an LTE network), so that the SMS information can be sent through the NAS information sending mode under the second communication network, improving the success rate of the SMS service of the target terminal and improving the user's basic communication experience.

[0057] The following will detail the specific implementation manners of this disclosure with reference to the accompanying drawings.

[0058] Figure 1It is a flowchart of an information transmission method shown according to an exemplary embodiment. This method can be applied to a terminal, such as Figure 1 as shown, and includes the following steps.

[0059] In step S101, when the short message service (SMS) information sent by the target terminal fails, obtain the location update signaling sent by the network device to the target terminal.

[0060] As mentioned above, the present disclosure is mainly applied to the scenario where the terminal performs SMS services in the SA networking mode of the 5G network. Therefore, the target terminal includes a terminal supporting the 5G network. And when the current first communication network of the target terminal is a specified communication network, when the target terminal fails to send SMS information, the location update signaling can be obtained by executing this step. The specified communication network can include, for example, the SA network.

[0061] In addition, the network device can be, for example, a base station. After the target terminal camps on the first communication network corresponding to the base station, the base station can send the location update signaling to the target terminal. The location update signaling is used to represent the network configuration information corresponding to the first communication network. The network configuration information can include, for example, whether the 5G core network corresponding to the first communication network deploys an SMSF network element. Generally, after the 5G core network deploys the SMSF network element, it can support the terminal to transmit SMS information based on the SMS over NAS information sending mode.

[0062] In step S102, when it is determined according to the location update signaling that the current first communication network of the target terminal does not support the non-access stratum (NAS) information sending mode, switch the first communication network to a second communication network, and the network mode of the second communication network is lower than that of the first communication network.

[0063] Among them, the NAS information sending mode is the SMS over NAS information sending mode. The location update signaling includes an indication message for indicating whether the first communication network supports the NAS information sending mode. The second communication network can include, for example, the 4G LTE network, or other network services with a network mode lower than the current first communication network, such as the 3G network.

[0064] In one implementation, when the indication message is preset identification information, it is determined that the first communication network does not support the NAS information sending mode. For example, if the SMSF network element is not deployed in the 5G core network in the current network configuration, the terminal does not support the transmission of SMS information based on the SMS over NAS information sending mode. In this case, the indication message contains the preset identification information, and the preset identification information is used to indicate that the SMSF network element is not deployed in the 5G core network corresponding to the terminal's network attachment. In other words, the preset identification information is used to indicate that the first communication network does not support the NAS information sending mode.

[0065] In step S103, send SMS information through the NAS information sending mode under the second communication network.

[0066] Exemplarily, taking the second communication network as an LTE network, since the core network does not need to deploy the SMSF network element when the 4G LTE network transmits SMS information based on the SMS over NAS information sending mode, the 4G LTE network can normally transmit SMS information through the NAS information sending mode.

[0067] Using the above method, when the target terminal fails to send SMS information outward, it can be determined whether the first communication network where the target terminal is attached supports the NAS information sending mode (i.e., the SMS over NAS method). If it is determined that the first communication network does not support the non-access stratum NAS information sending mode, the first communication network can be switched to the second communication network (for example, switching the 5G SA network of the target terminal to the LTE network), so that SMS information can be sent through the NAS information sending mode under the second communication network, improving the success rate of the SMS service of the target terminal and enhancing the user's basic communication experience.

[0068] Figure 2 is according to Figure 1 shown in the flowchart of an information transmission method according to the illustrated embodiment, as Figure 2 shown, the method includes the following steps:

[0069] In step S201, send SMS information outward through the IP multimedia subsystem IMS information sending mode.

[0070] Among them, the IMS information sending mode here can be, for example, SMS over IMS.

[0071] When a terminal sends and receives SMS messages over a 5G network, it mostly does so based on two message sending modes: SMS over NAS and SMS over IMS. And when the terminal conducts SMS services over a 5G network, it usually prefers to use the SMS over IMS mode to send SMS messages outward.

[0072] In step S202, when receiving a preset error code sent by a network device, it is determined that the target terminal fails to send an SMS message outward.

[0073] Among them, the network device can be, for example, a base station.

[0074] In the case of current network anomalies or cell failures in the area, there will be a situation where the terminal fails to send SMS messages based on the SMS over IMS mode. At this time, the target terminal usually receives a preset error code (such as 405 METHOD_NOT_ALLOWED, etc.) sent by the network device. Therefore, when the target terminal receives the preset error code sent by the network device, it can be determined that the target terminal fails to send the SMS message outward.

[0075] In step S203, obtain the registration signaling sent by the network device to the target terminal.

[0076] After the target terminal camps on the first communication network corresponding to the network device, the network device can send the registration signaling to the target terminal. The registration signaling is used to represent the network configuration information corresponding to the first communication network. The network configuration information can include, for example, whether the 5G core network corresponding to the first communication network deploys an SMSF network element. Usually, after the 5G core network deploys the SMSF network element, it can support the terminal to transmit SMS messages based on the SMS over NAS message sending mode.

[0077] In step S204, when it is determined according to the registration signaling that the current first communication network of the target terminal does not support the non-access stratum NAS message sending mode, switch the first communication network to a second communication network.

[0078] Among them, the registration signaling includes an indication message for indicating whether the first communication network supports the NAS message sending mode. The second communication network can include, for example, a 4G LTE network, or other network services with a network mode lower than the current first communication network, such as a 3G network.

[0079] In one implementation manner, when the indication message is preset identification information, it is determined that the first communication network does not support the NAS information sending mode. For example, if the SMSF network element is not deployed in the network configuration of the currently registered network (i.e., the first communication network) of the terminal, then the terminal does not support the transmission of SMS information based on the SMS over NAS information sending mode. In this case, the indication message contains the preset identification information, and the preset identification information is used to indicate that the SMSF network element is not deployed in the 5G core network corresponding to the registered network of the terminal. In other words, the preset identification information is used to indicate that the first communication network does not support the NAS information sending mode.

[0080] It should be noted that in the actual application scenario, at present, most of the stand-alone networking SA networks under 5G networks do not deploy the SMSF network element. Therefore, the network side does not support the SMS over NAS information sending mode. Therefore, when the first communication network where the multi-target terminal is currently registered is an SA network, after the target terminal fails to perform the SMS service using the SMS over IMS method, if it still retries SMS over NAS according to the original solution, it will also fail, resulting in the failure of the user's SMS service. Therefore, in the present disclosure, when it is determined that the current first communication network of the target terminal does not support the non-access stratum NAS information sending mode, the first communication network can be switched to a second communication network with a lower network mode, so as to implement the SMS service under the second communication network.

[0081] In step S205, send the SMS information through the NAS information sending mode under the second communication network.

[0082] Exemplarily, taking the second communication network as an LTE network as an example, since the core network does not need to deploy the SMSF network element when the 4G LTE network transmits SMS information based on the SMS over NAS information sending mode, therefore, based on the 4G LTE network, the SMS information can be normally transmitted through the NAS information sending mode.

[0083] In step S206, obtain the occurrence times of the target event corresponding to the target terminal, and update the preset duration of the preset timer according to the occurrence times.

[0084] For example, the occurrence times of the target event corresponding to the target terminal can be recorded by a pre-set counter. The target event is the event that the target terminal resides in the same cell at both the first moment and the second moment. The first moment is the moment when the target terminal resides in the first communication network before switching the communication network of the target terminal to the second communication network. The second moment is the moment when the target terminal resides in the first communication network after switching the communication network of the target terminal back from the second communication network to the first communication network.

[0085] The network mode of the first communication network is higher than that of the second communication network. Since the higher the network mode, the better the corresponding communication quality. Therefore, in addition to solving the problem that the target terminal cannot send and receive SMS messages based on the NAS information sending mode under the first communication network, it is also necessary to ensure the highest possible communication quality of the user terminal to the greatest extent. Therefore, after the present disclosure controls the target terminal to switch from the first communication network to the second communication network, the pre-set timer can be used to record the duration after the target terminal switches from the first communication network to the second communication network, so that when the duration reaches the preset duration, the network residence of the target terminal can be timely switched back from the second communication network to the first communication network with a higher network mode.

[0086] Wherein, the initial values of the pre-set counter and the pre-set timer can be initialized when the target terminal first resides in the first communication network. For example, the initial value of the pre-set counter is 0, and the initial value of the preset duration of the pre-set timer can be set to 15 seconds.

[0087] In a possible implementation manner of this step, the preset duration of the pre-set timer can be updated according to the occurrence times of the target event in the following manner:

[0088] T1 = T0 + n * k

[0089] Wherein, T1 represents the preset duration of the updated pre-set timer, T0 represents the preset duration of the pre-set timer before update, n represents the occurrence times of the target event recorded by the pre-set counter, k represents the preset time increment, and the specific value of k can be defined according to actual requirements, and the present disclosure does not limit this.

[0090] In step S207, record the duration after the target terminal switches from the first communication network to the second communication network, and when the duration reaches the preset duration, switch the communication network of the target terminal from the second communication network to the first communication network.

[0091] Wherein, the duration after the target terminal switches from the first communication network to the second communication network can be recorded by a pre-set timer.

[0092] As mentioned above, on the premise of solving the problem that the target terminal cannot send and receive SMS messages based on the NAS information sending mode under the first communication network, it is also necessary to ensure the relatively high communication quality of the user terminal to the greatest extent. Therefore, after the present disclosure controls the target terminal to switch from the first communication network to the second communication network, the preset timer can record the duration after the target terminal switches from the first communication network to the second communication network, and when the duration reaches the preset duration, the present disclosure can timely switch the network registration of the target terminal back from the second communication network to the first communication network with a higher network mode.

[0093] It should also be noted that when the time of the preset timer reaches the preset duration, after the communication network of the target terminal is switched from the second communication network to the first communication network, when the time of the preset timer does not reach the preset duration, the target terminal can receive SMS messages sent by other terminals through the NAS information sending mode under the second communication network, so as to realize the reception and sending of SMS messages.

[0094] In step S208, a first cell identifier is obtained, and the first cell identifier is the cell where the target terminal resides when the target terminal fails to send an SMS message outward.

[0095] Wherein, the first cell identifier and the second cell identifier mentioned later can be the CGI (Cell Global Identifier) or TAC (Tracking Area Code) of the cell.

[0096] In step S209, a second cell identifier of the cell where the target terminal resides is obtained.

[0097] The second cell identifier is the cell identifier of the cell where the target terminal resides after the communication network of the target terminal is switched back from the second communication network to the first communication network.

[0098] In step S210, the occurrence times of the target event are updated according to the first cell identifier and the second cell identifier, and the first cell identifier is the cell where the target terminal resides when the target terminal fails to send an SMS message outward.

[0099] When the target terminal fails to send the SMS message externally and the current first communication network of the target terminal does not support the non-access stratum (NAS) information sending mode, if it is determined according to the first cell identifier and the second cell identifier that the serving cell where the target terminal fails to send the SMS message externally is the same as the serving cell where the target terminal camps after switching back from the second communication network to the first communication network, after switching the target terminal back from the second communication network to the first communication network, it is very likely that the current first communication network of the target terminal also does not support the NAS information sending mode. Therefore, in this step, if the first cell identifier and the second cell identifier are the same, the occurrence count can be increased by a preset amplitude, so that when updating the preset duration of the preset timer according to the occurrence count of the target event, the preset duration of the preset timer can be appropriately increased, thereby increasing the SMS message sending and receiving time and further improving the success rate of SMS message sending and receiving; if the first cell identifier and the second cell identifier are different, the occurrence count can be cleared to re-monitor the SMS service under the communication network corresponding to the current serving cell.

[0100] By adopting the above method, when the target terminal fails to send the SMS message externally, it can be determined whether the first communication network where the target terminal camps supports the NAS information sending mode (i.e., SMS over NAS mode). If it is determined that the first communication network does not support the NAS information sending mode of the non-access stratum, the first communication network can be switched to the second communication network (for example, switching the 5G SA network of the target terminal to the LTE network), so that the SMS message can be sent through the NAS information sending mode under the second communication network, improving the success rate of the SMS service of the target terminal and enhancing the basic communication experience of the user.
