[0073] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0074] The communication connection processing method provided by the embodiments of the present application can be applied in the application environment as shown in FIG. 1. Wherein, the terminal side 101 communicates with the network side 102 through the network. In the case that the 3GPP signal is lost at the terminal side, the MPQUIC connection between the terminal side and the network side is maintained; and the network side can release the MPQUIC connection based on the control of the terminal side based on the release of the associated information.

[0075] The network side 102 includes an AMF (Access and Mobility Management Function) network element, an SMF (Session Management Function) network element, a UPF (User Plane Function) network element, a PCF (Policy Control function) network element and a UDM (User Data Management) network element.

[0076] In an embodiment, as shown in FIG. 2, in the process that the terminal side 101 communicates with the network side 102 through the network, the following contents can be included: the terminal side realizes the MPQUIC connection between the UPF network element through the 3GPP access technology and the Non-3GPP access technology, through the AMF network element and the SMF network element in the network side; the terminal side acquires the ip information through the Non-3GPP access; and the terminal side verifies the path validity between the terminal side and the UPF network element through the Non-3GPP access; the UPF network element reports the path validity verification success event; the UPF network element sends the N4 (a type of session) session establishment request to the SMF network element, the SMF network element feeds back the N4 session establishment response to the UPF network element, and the UPF network element and the SMF network element adaptively adjust the N4 session according to their own conditions. In an embodiment, if the 3GPP signal is lost at the terminal side, the 3GPP access is not available, at this time, the 3GPP side is still in the registration state, so that the path between the terminal side of the non 3GPP side and the UPF network element can still be used, then the terminal side and the network side can realize the data exchange through the QUIC path on the Non-3GPP access.

[0077] In one embodiment, according to the above, as shown in FIG. 3, the terminal side is connected with the UPF network element through 3GPP access technology and Non-3GPP access technology, the terminal side is connected with the AMF network element through N1 session, and the 3GPP access technology is connected through N2 session; the UPF network element is connected with the SMF network element through N4 session; the SMF network element is connected with the AMF network element and the PCF network element through N11 session and N7 session, respectively.

[0078] The terminal side can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things device can be a smart speaker, a smart television, a smart air conditioner, a smart vehicle device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. It also includes new types of terminal devices, such as unmanned aerial vehicles and satellite communication terminals, which are essentially devices that receive electromagnetic waves transmitted by network devices for communication, and are not limited herein.

[0079] In one embodiment, as shown in FIG. 4, a communication connection processing method is provided, applied to a terminal side, and specifically includes the following steps:

[0080] S401, in the case of losing 3GPP signal, maintaining the MPQUIC connection between the terminal side and the network side.

[0081] It should be noted that the connection state of the 3GPP signal can be determined to determine whether the 3GPP signal is lost at the current time.

[0082] In one embodiment of the present application, the terminal side can determine whether the 3GPP signal is lost at the current time by querying the network connection state in real time. Specifically, if the network connection state shows that it is not connected, or shows that it is connected to other types of networks, it can be determined that the terminal side loses the 3GPP signal at the current time.

[0083] In another embodiment of the present application, the terminal side can also verify whether the current position of the terminal side belongs to the signal coverage range of the 3GPP signal. Specifically, if the current position of the terminal side does not belong to the signal coverage range of the 3GPP signal, it is determined that the terminal side loses the 3GPP signal at the current time; if the current position of the terminal side belongs to the signal coverage range of the 3GPP signal, it is determined that the terminal side does not lose the 3GPP signal at the current time.

[0084] Further, in order to prevent the terminal side from implicitly separating due to the loss of the 3GPP signal, and further, causing the terminal side to release the MPQUIC connection, so that the MPQUIC states of the terminal side and the network side are inconsistent, the terminal side can be pre-configured with the keep instruction information, which is used to instruct the terminal side to keep the MPQUIC connection with the network side in the case of losing the 3GPP signal.

[0085] In an embodiment of the present application, the keep instruction information can be pre-configured in the terminal side and continuously kept in the trigger state, and further, in the case of losing the 3GPP signal in the terminal side, it is verified whether there is an event of pre-configuring the keep instruction information; if not, the terminal side keeps the MPQUIC connection with the network side in the case of losing the 3GPP signal according to the keep instruction information; if yes, the MPQUIC state of the terminal side is not affected, and if the terminal side implicitly separates, the MPQUIC connection is released.

[0086] The event of pre-configuring the keep instruction information can include, but is not limited to, the terminal side receiving the release MPQUIC connection instruction information sent by the network side, the current time reaching the pre-configured release MPQUIC connection preset time in the terminal side, the current time reaching the preset time in which the network side pre-instructs the terminal side to release the MPQUIC connection, and the like.

[0087] In an embodiment of the present application, the keep instruction information can be pre-configured by the network side and sent to the terminal side, and further, in the case of losing the 3GPP signal in the terminal side, it is verified whether the terminal side receives the keep instruction information sent by the network side; if yes, the terminal side keeps the MPQUIC connection with the network side in the case of losing the 3GPP signal; if not, the MPQUIC state of the terminal side is not affected, and if the terminal side implicitly separates, the MPQUIC connection is released.

[0088] S402, releasing the MPQUIC connection according to the release association information provided by the network side.

[0089] The release association information is used to represent the information instructing the terminal side to release the MPQUIC connection association, and the release association information can include the release instruction, the timing instruction information, and other information instructing the terminal side to release the MPQUIC connection association.

[0090] It should be noted that, in order to keep the MPQUIC states of the terminal side and the network side consistent, whether the network side will release the MPQUIC connection at the current time can be acquired or predicted; the MPQUIC state of the terminal side is determined according to the MPQUIC state of the network side; and then, whether to perform the operation of keeping the MPQUIC connection with the network side is determined according to the MPQUIC state of the terminal side.

[0091] As an embodiment, in the case that the 3GPP signal is not lost at the terminal side, whether the network side will release the MPQUIC connection at the current time can be acquired through the 3GPP access operation between the terminal side and the network side, and then, in the case that the MPQUIC state of the network side is to release the MPQUIC connection, the terminal side releases the MPQUIC connection; and in the case that the MPQUIC state of the network side is to keep the MPQUIC connection, the terminal side keeps the MPQUIC connection with the network side.

[0092] As an embodiment, in the case that the 3GPP signal is lost at the terminal side, the MPQUIC state of the network side cannot be directly acquired, and then, whether the terminal side receives the release association information provided by the network side at the current time or at a historical time is verified, if the release association information is received, the MPQUIC connection is released according to the release association information provided by the network side.

[0093] In an embodiment of the present application, when the MPQUIC connection is released according to the release association information provided by the network side, if the release instruction is included in the release association information, the operation of releasing the MPQUIC connection is performed; if the release instruction is not included in the release association information, whether the release condition in the release association information is met at the current time is verified in real time, if the release condition is met, the operation of releasing the MPQUIC connection is performed, if the release condition is not met, the step of verifying whether the release condition in the release association information is met at the current time is continuously performed until the MPQUIC connection is released, or the release association information expires or is deleted.

[0094] As an example, the release condition in the release association information can be that when the distance between the position of the terminal side and the edge of the 3GPP signal coverage range exceeds a preset distance, the operation of releasing the MPQUIC connection is performed; otherwise, when the distance between the position of the terminal side and the edge of the 3GPP signal coverage range does not exceed the preset distance, the MPQUIC connection between the terminal side and the network side is kept.

[0095] As another example, the release condition in the release association information can also be: when the cumulative duration of missing 3GPP signals exceeds a preset duration, the operation of releasing the MPQUIC connection is performed; otherwise, when the cumulative duration of missing 3GPP signals does not exceed the preset duration, the MPQUIC connection between the terminal side and the network side is maintained.

[0096] As another example, the release condition in the release association information can also be: verifying whether there is a data transmission requirement for the network side at the terminal side; if there is no data transmission requirement for the network side at the terminal side, the operation of releasing the MPQUIC connection is performed; otherwise, if there is a data transmission requirement for the network side at the terminal side, the MPQUIC connection between the terminal side and the network side is maintained.

[0097] The above communication connection processing method, in the case that the 3GPP signal is lost at the terminal side, the terminal side maintains the MPQUIC connection with the network side; and the network side can release the MPQUIC connection based on the control of the terminal side based on the release association information. According to the above content, it can be known that, in the case that the 3GPP signal is lost at the terminal side, by maintaining the MPQUIC connection with the network side, it is prevented that the terminal side releases the MPQUIC connection due to the implicit separation at the terminal side, so that the case that the MPQUIC states of the terminal side and the network side are inconsistent occurs; further, since the terminal side releases the MPQUIC connection based on the release association information provided by the network side, it is further prevented that the case that the MPQUIC states of the terminal side and the network side are inconsistent occurs, and it is realized that the stable connection between the terminal side and the network side can be ensured in the case that the 3GPP signal is lost, so that the terminal side and the network side can still communicate stably in the case that the 3GPP signal is lost.

[0098] In an embodiment, the network side can pre-send the terminal side with the maintenance indication information to ensure that the terminal side continuously maintains the MPQUIC connection, so that in the case that the third generation partnership project 3GPP signal is lost at the terminal side, the MPQUIC connection between the terminal side and the network side can be maintained in the case that the 3GPP signal is lost according to the maintenance indication information sent by the network side.

[0099] The maintenance indication information is used to instruct the terminal side to maintain the MPQUIC connection with the network side in the case that the 3GPP signal is lost.

[0100] In an embodiment, the network side can send the terminal side with the maintenance indication information in the form of a NAS message, so that the terminal side can receive the NAS message sent by the network side; wherein the maintenance indication information is carried in the NAS message, so that the terminal side can receive the maintenance indication information sent by the network side.

[0101] In one embodiment, the NAS message carrying the keep indication information can be sent from the AMF network element in the network side to the terminal side, so that the terminal side can keep the MPQUIC connection with the network side according to the keep indication information sent by the network side in the case of losing the 3GPP signal.

[0102] The communication connection processing method makes the terminal side keep the MPQUIC connection with the network side in the case of losing the 3GPP signal according to the keep indication information sent by the network side, prevents the MPQUIC state of the terminal side from being inconsistent with that of the network side, and makes the terminal side and the network side both keep the MPQUIC state of the MPQUIC connection.

[0103] In one embodiment, if the terminal side includes the first timer in the storage device corresponding to the terminal side, the terminal side starts the first timer in the case of losing the 3GPP signal. Therefore, in the process of releasing the MPQUIC connection according to the release association information provided by the network side, the terminal side can determine that the timing duration of the first timer reaches the set duration according to the timing indication information in the release association information, and then release the MPQUIC connection.

[0104] The first timer can be pre-stored in the storage device of the terminal side by the terminal side, or sent to the terminal side by the network side, and stored in the storage device of the terminal side by the terminal side after being received.

[0105] The timing indication information includes the set duration, and is also used to indicate that the MPQUIC connection is released in the case that the timing duration of the first timer corresponding to the terminal side reaches the set duration.

[0106] In one embodiment, if the timing indication information in the release association information, the terminal side starts the first timer in the case of losing the 3GPP signal, and verifies in real time whether the timing duration of the first timer reaches the set duration. If not, the terminal side keeps the MPQUIC connection between the terminal side and the network side. If yes, the terminal side releases the MPQUIC connection.

[0107] The timing indication information is carried in the NAS message. Further, the NAS message is a registration acceptance message, a user session establishment acceptance message, or a downlink NAS transmission message.

[0108] In an embodiment of the present application, as shown in FIG. 5, the AMF network element in the network side sends a NAS message carrying the keep instruction information and the first timer to the terminal side; after receiving the first timer, the terminal side stores the first timer in the storage device, keeps the MPQUIC connection between the terminal side and the network side in the case of losing the 3GPP signal, starts the first timer, and verifies whether the timing duration of the first timer reaches the set duration according to the timing instruction information in the release association information. If it is determined that the timing duration of the first timer reaches the set duration, the MPQUIC connection is released. Further, after the terminal side releases the MPQUIC connection, a notification message can be sent to the UPF network element to inform the UPF network element that the terminal side releases the MPQUIC connection.

[0109] The communication connection processing method judges whether to release the MPQUIC connection through the timing duration of the first timer. The operation of triggering the terminal side to release the MPQUIC connection according to different situations is realized, and the situation that the MPQUIC states of the terminal side and the network side are inconsistent due to the terminal side losing the 3GPP signal is prevented. The stable connection between the terminal side and the network side can be ensured in the case of losing the 3GPP signal, so that the stable multipath transmission and migration between the terminal side and the network side can still be performed in the case of losing the 3GPP signal.

[0110] In an embodiment, as shown in FIG. 6, when it is necessary to release the MPQUIC connection according to the release association information provided by the network side, the following contents can be included:

[0111] S601, receiving the release association information sent by the network side.

[0112] The release association information carries a release instruction. Further, the release instruction is sent after the MPQUIC connection is released in the case that the timing duration of the second timer of the network side reaches the preset duration.

[0113] It should be noted that the release instruction is used to instruct the terminal side to perform the operation of releasing the MPQUIC connection.

[0114] S602, releasing the MPQUIC connection according to the release instruction.

[0115] In an embodiment of the present application, as shown in FIG. 7, the AMF network element in the network side sends a NAS message carrying the keep instruction information to the terminal side; the terminal side keeps the MPQUIC connection between the terminal side and the network side in the case of losing the 3GPP signal according to the keep instruction information sent by the network side, and releases the MPQUIC connection according to the release instruction in the release association information received by the terminal side, wherein the release association information carries the release instruction.

[0116] In another embodiment of the present application, as shown in FIG. 8, if the holding indication information can be pre-set in the terminal side, and the trigger state is continuously maintained; the terminal side does not need to receive the NAS message carrying the holding indication information sent by the AMF network element to the terminal side, so that in the case of losing the 3GPP signal at the terminal side, the MPQUIC connection between the terminal side and the network side can be directly maintained, if the terminal side receives the release association information sent by the network side; wherein the release association information carries a release instruction; the terminal side releases the MPQUIC connection according to the release instruction.

[0117] The above communication connection processing method, by receiving the release instruction sent by the network side, executes the release of the MPQUIC connection. It realizes the operation of triggering the terminal side to release the MPQUIC connection according to different situations, prevents the situation that the MPQUIC state of the terminal side and the network side is inconsistent due to the loss of the 3GPP signal at the terminal side; realizes that in the case of losing the 3GPP signal, the stable connection between the terminal side and the network side can also be guaranteed, so that the terminal side and the network side can still perform stable multiplexing and migration in the case of losing the 3GPP signal.

[0118] In an embodiment, as shown in FIG. 9, when it is necessary to release the MPQUIC connection according to the release association information provided by the network side, the following contents can also be included:

[0119] S901, in the case of re-acquiring the 3GPP signal, obtaining the release association information from the network side.

[0120] Wherein, the release association information carries the MPQUIC state; further, the MPQUIC state is used to represent the MPQUIC state of the network side.

[0121] In an embodiment of the present application, the release association information acquisition request can be sent to the network side to indicate the network side to feed back the release association information to the terminal side, so as to realize the operation of obtaining the release association information from the network side in the case of re-acquiring the 3GPP signal.

[0122] S902, in the case of the MPQUIC state representing that the network side has released the MPQUIC connection, releasing the MPQUIC connection.

[0123] In an embodiment of the present application, in order to ensure consistency of the MPQUIC state between the terminal side and the network side, the MPQUIC state of the terminal side needs to be adjusted according to the MPQUIC state of the network side, so that the MPQUIC states of the terminal side and the network side remain consistent. Therefore, in the case that the MPQUIC state indicates that the network side has released the MPQUIC connection, the MPQUIC connection is released; in the case that the MPQUIC state indicates that the network side maintains the MPQUIC connection, the MPQUIC connection between the terminal side and the network side is also maintained.

[0124] The above communication connection processing method releases the MPQUIC connection of the terminal side by releasing the MPQUIC state carried in the release association information in the case of reacquiring the 3GPP signal. The operation of triggering the terminal side to release the MPQUIC connection according to different situations is realized, and the situation that the MPQUIC states of the terminal side and the network side are inconsistent due to the loss of the 3GPP signal by the terminal side is prevented. The stable connection between the terminal side and the network side can also be ensured in the case of losing the 3GPP signal, so that the terminal side and the network side can still perform stable multi-path transmission and migration in the case of losing the 3GPP signal.

[0125] In an embodiment, a communication connection processing method is provided, which is applied to the network side and specifically includes the following steps: in the case that the terminal side loses the 3GPP signal and maintains the MPQUIC connection with the network side, controlling the terminal side to release the MPQUIC connection based on the release association information.

[0126] The release association information is used to represent information indicating that the terminal side releases the MPQUIC connection association. The release association information can include release instructions, timing indication information, and other information indicating that the terminal side releases the MPQUIC connection association.

[0127] In an embodiment of the present application, when the network side controls the terminal side to release the MPQUIC connection according to the release association information, if the release association information contains a release instruction, the operation of releasing the MPQUIC connection is performed; if the release association information does not contain a release instruction, it can be verified in real time whether the release condition in the release association information is reached at the current time; if it is reached, the operation of releasing the MPQUIC connection is performed; if it is not reached, the step of verifying whether the release condition in the release association information is reached at the current time is continuously performed until the MPQUIC connection is released, or the release association information expires or is deleted.

[0128] As an example, the release condition in the release-associated information can be: when the distance between the terminal-side self-position and the edge of the 3GPP signal coverage range exceeds a preset distance, the operation of releasing the MPQUIC connection is performed; otherwise, when the distance between the terminal-side self-position and the edge of the 3GPP signal coverage range does not exceed the preset distance, the MPQUIC connection between the terminal side and the network side is maintained.

[0129] As another example, the release condition in the release-associated information can also be: when the cumulative duration of losing the 3GPP signal exceeds a preset duration, the operation of releasing the MPQUIC connection is performed; otherwise, when the cumulative duration of losing the 3GPP signal does not exceed the preset duration, the MPQUIC connection between the terminal side and the network side is maintained.

[0130] As yet another example, the release condition in the release-associated information can also be: verifying whether the terminal side has a data transmission demand for the network side; if the terminal side does not have a data transmission demand for the network side, the operation of releasing the MPQUIC connection is performed; otherwise, if the terminal side has a data transmission demand for the network side, the MPQUIC connection between the terminal side and the network side is maintained.

[0131] The above communication connection processing method, in the case that the terminal side loses the 3GPP signal, the terminal side maintains the MPQUIC connection with the network side; and the network side can release the MPQUIC connection based on the control of the terminal side based on the release-associated information. According to the above content, it can be known that, in the case that the terminal side loses the 3GPP signal, by maintaining the MPQUIC connection with the network side, it is prevented that the terminal side releases the MPQUIC connection due to the occurrence of the implicit separation of the terminal side, so that the situation that the MPQUIC states of the terminal side and the network side are inconsistent occurs; further, since the terminal side releases the MPQUIC connection based on the release-associated information provided by the network side, it is further prevented that the situation that the MPQUIC states of the terminal side and the network side are inconsistent occurs, and it is realized that in the case that the 3GPP signal is lost, the stable connection between the terminal side and the network side can also be ensured, so that the terminal side and the network side can still communicate stably in the case that the 3GPP signal is lost.

[0132] In an embodiment, the network side can pre-send the maintenance indication information to the terminal side to ensure that the terminal side continuously maintains the MPQUIC connection, so that in the case that the terminal side loses the 3GPP signal, the MPQUIC connection between the terminal side and the network side can be maintained according to the maintenance indication information sent by the network side in the case that the 3GPP signal is lost.

[0133] In an embodiment, the terminal side is sent the keeping indication information; wherein the keeping indication information is used to instruct the terminal side to keep the MPQUIC connection with the network side in the case of losing the 3GPP signal.

[0134] Further, the network side can send the keeping indication information to the terminal side in the form of a NAS message, and thus the NAS message is sent to the terminal side; wherein the keeping indication information is carried in the NAS message.

[0135] The above communication connection processing method makes the terminal side keep the MPQUIC connection with the network side in the case of losing the 3GPP signal through the keeping indication information sent by the network side, prevents the MPQUIC state of the terminal side from being inconsistent with that of the network side, and makes the terminal side and the network side both keep the MPQUIC state of the MPQUIC connection.

[0136] In an embodiment, if the terminal side has the first timer in the corresponding storage device, and the terminal side starts the first timer in the case of losing the 3GPP signal, the release association information can include timing indication information; the timing indication information is used to instruct the terminal side to release the MPQUIC connection in the case that the timing duration of the first timer reaches a set duration.

[0137] The timing indication information is carried in a NAS message. Further, the NAS message is a registration acceptance message, a user session establishment acceptance message, or a downlink NAS transmission message.

[0138] The above communication connection processing method sends the terminal side the timing indication information, so that the terminal side can determine whether to release the MPQUIC connection according to the timing duration of the first timer. The operation of triggering the terminal side to release the MPQUIC connection according to different situations is realized, the case that the MPQUIC state of the terminal side is inconsistent with that of the network side due to the terminal side losing the 3GPP signal is prevented, and stable connection between the terminal side and the network side in the case of losing the 3GPP signal is ensured, so that the terminal side and the network side can still perform stable multi-path transmission and migration in the case of losing the 3GPP signal.

[0139] In an embodiment, when it is needed to control the terminal side to release the MPQUIC connection based on the release association information, the terminal side is sent the release association information; wherein the release association information carries a release instruction; the release instruction is used to instruct the terminal side to release the MPQUIC connection.

[0140] It should be noted that the storage device at the network side is provided with a second timer, the second timer is used to start timing operation when the 3GPP signal is lost at the terminal side, and further, in the case that the timing duration of the second timer reaches a preset duration, the release association information is sent to the terminal side.

[0141] The preset duration can be set or adjusted according to actual conditions and communication requirements of the terminal side and the network side, and the value range of the preset duration is not limited here.

[0142] The above communication connection processing method judges whether to release the MPQUIC connection through the timing duration of the second timer. The operation of triggering the terminal side to release the MPQUIC connection according to different situations is realized, and the situation that the MPQUIC states of the terminal side and the network side are inconsistent due to the loss of the 3GPP signal at the terminal side is prevented. The stable connection between the terminal side and the network side can be ensured in the case of losing the 3GPP signal, so that the terminal side and the network side can still perform stable multipath transmission and migration in the case of losing the 3GPP signal.

[0143] In an embodiment, when it is necessary to release the MPQUIC connection according to the release association information provided by the network side, the following content can be included: in the case that the 3GPP signal is reacquired at the terminal side, the release association information is sent to the terminal side; wherein the MPQUIC state of the network side is carried in the release association information; the release association information is used to instruct the terminal side to release the MPQUIC connection in the case that the MPQUIC state represents that the network side has released the MPQUIC connection.

[0144] In an embodiment of the present application, in order to ensure the consistency of the MPQUIC states between the terminal side and the network side, the MPQUIC state of the terminal side needs to be adjusted according to the MPQUIC state of the network side, so that the MPQUIC states of the terminal side and the network side remain consistent. Therefore, in the case that the MPQUIC state represents that the network side has released the MPQUIC connection, the MPQUIC connection is released; in the case that the MPQUIC state represents that the network side maintains the MPQUIC connection, the multipath transmission protocol MPQUIC connection between the terminal side and the network side is also maintained.

[0145] The communication connection processing method according to the above embodiment, in the case that the 3GPP signal is reacquired at the terminal side, sends release association information to the terminal side, and releases the MPQUIC connection at the terminal side according to the MPQUIC state of the network side carried in the release association information. The operation of triggering the terminal side to release the MPQUIC connection according to different situations is realized, and the situation that the MPQUIC state of the terminal side and the network side is inconsistent due to the terminal side losing the 3GPP signal is prevented. The stable connection between the terminal side and the network side is ensured in the case that the 3GPP signal is lost, and the stable multipath transmission and migration between the terminal side and the network side can still be realized in the case that the 3GPP signal is lost.

According to the above content, in a case where a 3GPP signal is lost at the terminal side, by keeping the MPQUIC connection between the terminal side and the network side, it is prevented that the terminal side releases the MPQUIC connection due to implicit separation at the terminal side, so that a case where MPQUIC states of the terminal side and the network side are inconsistent occurs; further, since the terminal side releases the MPQUIC connection based on the release association information provided by the network side, it is further prevented that the case where the MPQUIC states of the terminal side and the network side are inconsistent occurs, so that stable connection between the terminal side and the network side is ensured in a case where a 3GPP signal is lost, so that the terminal side and the network side can still communicate stably in a case where a 3GPP signal is lost.
