[0071] In order to make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be given to the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0072] The communication connection processing method provided by the embodiments of the present application can be applied to, for example Figure 1The application environment shown. Among them, the terminal side 101 is connected with the network side 102 through the network. In the case of losing 3GPP signal at the terminal side, the terminal side keeps the MPQUIC connection between the terminal side and the network side; 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.

[0073] The network side 102 includes AMF (Access and Mobility Management Function, Access and Mobility Management Function) network element, SMF (Session Management Function, Session Management Function) network element, UPF (User Plane Function, User Plane Function) network element, PCF (Policy Control function, Policy Control function) network element and UDM (User Data Management, User Data Management) network element.

[0074] Among them, as Figure 2 shown, in the process of connecting the terminal side 101 with the network side 102 through the network, the following contents can be included: the terminal side realizes the MPQUIC connection between the terminal side and the UPF network element through the AMF network element and the SMF network element in the network side through 3GPP access technology and Non-3GPP access technology; the terminal side obtains ip information through Non-3GPP access; and the terminal side verifies the path validity between the terminal side and the UPF network element through Non-3GPP access; the UPF network element reports the path validity verification success event; the UPF network element sends N4 (a type of session) session establishment request to the SMF network element, and the SMF network element feeds back 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. Further, if the terminal side loses 3GPP signal, resulting in 3GPP access being not available, at this time, the 3GPP side is still in the registration state, so that the path between the terminal side and the UPF network element on the non 3GPP side can still be used, the terminal side and the network side can realize data exchange on the QUIC path of Non-3GPP access.

[0075] Further, according to the above content, as Figure 3 shown, the terminal side and the UPF network element are connected through 3GPP access technology and Non-3GPP access technology, the terminal side and the AMF network element are connected through N1 session and N2 session of 3GPP access technology; 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.

[0076] 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. New types of terminal devices such as unmanned aerial vehicles and satellite communication terminals are also included. In essence, all of these devices are devices that receive electromagnetic waves transmitted by network devices for communication, and are not limited herein.

[0077] In one embodiment, as shown in Figure 4 A communication connection processing method is provided, applied to a terminal side, and specifically includes the following steps:

[0078] S401, in the case of losing a 3GPP signal, maintaining an MPQUIC connection between the terminal side and a network side.

[0079] 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.

[0080] In an embodiment of the present application, the terminal side can query the network connection state in real time to determine whether the terminal side loses the 3GPP signal. 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.

[0081] 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.

[0082] Further, to prevent the terminal side from losing the 3GPP signal and causing implicit disconnection, and thus causing the terminal side to release the MPQUIC connection, so that the MPQUIC state of the terminal side and the network side is inconsistent, the terminal side can be pre-configured with a maintenance instruction. The maintenance instruction is used to instruct the terminal side to maintain the MPQUIC connection with the network side in the case of losing the 3GPP signal.

[0083] In an embodiment of the present application, the keep indication information can be pre-set in the terminal side and kept in a triggered state; then, in the case that the 3GPP signal is lost in the terminal side, it is verified whether there is an event of pre-set keep indication information termination; if not, the terminal side keeps the MPQUIC connection with the network side in the case that the 3GPP signal is lost according to the keep indication information; if yes, the MPQUIC state of the terminal side is not affected, and if implicit separation occurs in the terminal side, the MPQUIC connection is released.

[0084] The event of keep indication information termination can include, but is not limited to, the terminal side receiving the release MPQUIC connection indication information sent by the network side, the current time reaching the pre-set release MPQUIC connection time set by the terminal side, the current time reaching the pre-set time set by the network side for indicating the terminal side to release the MPQUIC connection, etc.

[0085] In an embodiment of the present application, the keep indication information can be pre-set in the terminal side and kept in a triggered state; then, in the case that the 3GPP signal is lost in the terminal side, it is verified whether there is an event of pre-set keep indication information termination; if not, the terminal side keeps the MPQUIC connection with the network side in the case that the 3GPP signal is lost according to the keep indication information; if yes, the MPQUIC state of the terminal side is not affected, and if implicit separation occurs in the terminal side, the MPQUIC connection is released.

[0086] S402, releasing the MPQUIC connection according to the release association information provided by the network side.

[0087] The release association information is used to represent the information indicating the terminal side to release the MPQUIC connection association, and can include the release instruction, the timing indication information and other information used to indicate the terminal side to release the MPQUIC connection association.

[0088] It should be noted that, in order to keep the MPQUIC states of the terminal side and the network side consistent, it can be acquired or predicted whether the network side will release the MPQUIC connection at the current time; the MPQUIC state of the terminal side is determined according to the MPQUIC state of the network side; then, it is judged whether to perform the operation of keeping the MPQUIC connection with the network side according to the MPQUIC state of the terminal side.

[0089] As an embodiment, in the case that the 3GPP signal is not lost at the terminal side, the network side whether to release the MPQUIC connection at the current time can be obtained 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; 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.

[0090] 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 obtained at this time, and then, whether the terminal side receives the release association information provided by the network side at the current time or at the 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.

[0091] In an embodiment of the present application, in the case that the MPQUIC connection is released according to the release association information provided by the network side, if the release instruction is contained in the release association information, the operation of releasing the MPQUIC connection is executed; if the release instruction is not contained in the release association information, whether the release condition in the release association information is reached at the current time is verified in real time; if the release condition is reached, the operation of releasing the MPQUIC connection is executed; if the release condition is not reached, the step of verifying whether the release condition in the release association information is reached at the current time is continuously executed until the MPQUIC connection is released, or the release association information expires or is deleted.

[0092] As an example, the release condition in the release association information can be that when the distance between the terminal side and the edge of the 3GPP signal coverage range exceeds the preset distance, the operation of releasing the MPQUIC connection is executed; otherwise, when the distance between the terminal side and the edge of the 3GPP signal coverage range does not exceed the preset distance, the multi-path transmission protocol (MPQUIC) connection between the terminal side and the network side is kept.

[0093] As another example, the release condition in the release association information can also be that when the cumulative duration of the lost 3GPP signal exceeds the preset duration, the operation of releasing the MPQUIC connection is executed; otherwise, when the cumulative duration of the lost 3GPP signal does not exceed the preset duration, the multi-path transmission protocol (MPQUIC) connection between the terminal side and the network side is kept.

[0094] As a further 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, performing the operation of releasing the MPQUIC connection; otherwise, if there is a data transmission requirement for the network side at the terminal side, maintaining the MPQUIC connection between the terminal side and the network side.

[0095] The above communication connection processing method maintains the MPQUIC connection between the terminal side and the network side when the 3GPP signal is lost at the terminal 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, when the 3GPP signal is lost at the terminal side, the MPQUIC connection between the terminal side and the network side is maintained to prevent the terminal side from releasing the MPQUIC connection due to implicit separation at the terminal side, so that the MPQUIC state inconsistency between the terminal side and the network side occurs. Further, since the terminal side releases the MPQUIC connection based on the release association information provided by the network side, the MPQUIC state inconsistency between the terminal side and the network side can be further prevented, and stable connection between the terminal side and the network side can be ensured even when the 3GPP signal is lost, so that stable communication between the terminal side and the network side can still be performed even when the 3GPP signal is lost.

[0096] 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 the terminal side can maintain the MPQUIC connection with the network side when the 3GPP signal is lost at the terminal side according to the maintenance indication information sent by the network side.

[0097] The maintenance indication information is used to instruct the terminal side to maintain the MPQUIC connection with the network side when the 3GPP signal is lost.

[0098] Further, the network side can send the maintenance indication information to the terminal side in the form of a NAS message, so that the terminal side can receive the NAS message sent by the network side; the maintenance indication information is carried in the NAS message to enable the terminal side to receive the maintenance indication information sent by the network side.

[0099] Specifically, the AMF network element in the network side can send the NAS message carrying the maintenance indication information to the terminal side, so that the terminal side can maintain the MPQUIC connection with the network side according to the maintenance indication information sent by the network side when the 3GPP signal is lost.

[0100] The communication connection processing method makes the terminal side maintain the MPQUIC connection with the network side in the case of losing the 3GPP signal through the holding indication information sent by the network side, prevents the MPQUIC state of the terminal side and the network side from being inconsistent, and makes the terminal side and the network side both maintain the MPQUIC state of the MPQUIC connection.

[0101] In an 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 first timer can be determined to reach the set time length according to the timing indication information in the release association information, and then the MPQUIC connection is released.

[0102] 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 the terminal side stores the first timer in the storage device of the terminal side after receiving the first timer.

[0103] The timing indication information includes the set time length, and the timing indication information is also used to indicate that the MPQUIC connection is released in the case that the timing length of the first timer corresponding to the terminal side reaches the set time length.

[0104] Specifically, 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 whether the timing length of the first timer reaches the set time length in real time; if not, the MPQUIC connection between the terminal side and the network side is maintained; if so, the MPQUIC connection is released.

[0105] 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.

[0106] In an embodiment of the present application, as Figure 5As shown, 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.

[0107] 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.

[0108] In an embodiment, as shown in Figure 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:

[0109] S601, receiving the release association information sent by the network side.

[0110] 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.

[0111] It should be noted that the release instruction is used to instruct the terminal side to perform the operation of releasing the MPQUIC connection.

[0112] S602, releasing the MPQUIC connection according to the release instruction.

[0113] In an embodiment of the present application, as shown in Figure 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. If the terminal side receives the release association information sent by the network side, the release association information carries a release instruction. The terminal side releases the MPQUIC connection according to the release instruction.

[0114] In another embodiment of the present application, as shown in Figure 8 If the terminal side keeps the indication information in advance and keeps the trigger state, 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 the MPQUIC connection between the terminal side and the network side can be directly kept in the case of losing the 3GPP signal at the terminal side, and the terminal side releases the MPQUIC connection according to the release instruction received from the network side, wherein the release instruction is carried in the release association information.

[0115] The above communication connection processing method releases the MPQUIC connection in the case of receiving the release instruction sent by the network side. 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 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 multiplexing and migration in the case of losing the 3GPP signal.

[0116] In an embodiment, as shown in Figure 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:

[0117] S901, in the case of re-acquiring the 3GPP signal, obtaining the release association information from the network side.

[0118] The release association information carries the MPQUIC state, and further, the MPQUIC state is used to represent the MPQUIC state of the network side.

[0119] 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.

[0120] S902, in the case of the MPQUIC state representing that the network side has released the MPQUIC connection, releasing the MPQUIC connection.

[0121] 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.

[0122] 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 that the 3GPP signal is reacquired. 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 that the 3GPP signal is lost, so that the terminal side and the network side can still perform stable multi-path transmission and migration in the case that the 3GPP signal is lost.

[0123] 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 3GPP signal is lost by the terminal side and the MPQUIC connection between the terminal side and the network side is maintained, the terminal side is controlled to release the MPQUIC connection based on release association information.

[0124] 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.

[0125] 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.

[0126] As an example, the release condition in the release-associated information can be: when the distance between 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 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 maintained.

[0127] 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.

[0128] As yet another example, the release condition in the release-associated information can also be: verifying whether the terminal side has a data transmission requirement for the network side; if the terminal side does not have a data transmission requirement for the network side, the operation of releasing the MPQUIC connection is performed; otherwise, if the terminal side has a data transmission requirement for the network side, the MPQUIC connection between the terminal side and the network side is maintained.

[0129] 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, 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 implicit separation of 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-associated information provided by the network side, it is further prevented that the MPQUIC states of the terminal side and the network side are inconsistent, and it is realized 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 communicate stably in the case of losing the 3GPP signal.

[0130] 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 of losing the 3GPP signal.

[0131] Specifically, the terminal side is sent the retention indication information; wherein the retention indication information is used to instruct the terminal side to retain the MPQUIC connection with the network side in the case of losing the 3GPP signal.

[0132] Further, the network side can send the retention indication information to the terminal side in the form of a NAS message, and therefore, the NAS message is sent to the terminal side; wherein the retention indication information is carried in the NAS message.

[0133] The communication connection processing method makes the terminal side retain the MPQUIC connection with the network side in the case of losing the 3GPP signal through the retention 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 retain the MPQUIC state of the MPQUIC connection.

[0134] In an embodiment, if the terminal side includes 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 the timing indication information; wherein 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 the set duration.

[0135] 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.

[0136] The communication connection processing method sends the timing indication information to the terminal side, 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 inconsistent MPQUIC state of the terminal side and 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-transmission and migration in the case of losing the 3GPP signal.

[0137] In an embodiment, when it is necessary to control the terminal side to release the MPQUIC connection based on the release association information, the release association information is sent to the terminal side; wherein the release association information carries the release instruction; and the release instruction is used to instruct the terminal side to release the MPQUIC connection.

[0138] 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.

[0139] 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.

[0140] 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 is 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.

[0141] 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.

[0142] 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.

[0143] The communication connection processing method according to the above embodiment can send release association information to the terminal side when the terminal side reacquires a 3GPP signal, and release the MPQUIC connection of 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 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.

[0145] Based on the same inventive concept, the embodiments of the present application also provide a communication connection processing device for implementing the above-mentioned communication connection processing method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme described in the above method, so the specific limitations in one or more communication connection processing device embodiments provided below can refer to the limitations of the communication connection processing method described above, and will not be repeated here.

[0146] In one embodiment, as shown in Figure 10 A communication connection processing device is provided, configured on the terminal side, comprising: a connection module 10 and a first release module 20, wherein:

[0147] The connection module 10 is configured to maintain the MPQUIC connection between the terminal side and the network side in the case of losing the 3GPP signal.

[0148] The first release module 20 is configured to release the MPQUIC connection according to the release association information provided by the network side.

[0154] In an embodiment, release association information sent by a network side is received; wherein the release association information carries a release instruction; according to the release instruction, the MPQUIC connection is released.

[0155] In an embodiment, the release instruction is sent after the MPQUIC connection is released in the case that the timing duration of a second timer of the network side reaches a preset duration.

[0156] In an embodiment, in the case that the 3GPP signal is reacquired, the release association information is acquired from the network side; wherein the release association information carries an MPQUIC state; in the case that the MPQUIC state represents that the network side has released the MPQUIC connection, the MPQUIC connection is released.

[0157] The above communication connection processing apparatus, in the case that the 3GPP signal is lost at the terminal side, keeps the MPQUIC connection between the terminal side and the network side; and the network side can control the terminal side to release the MPQUIC connection based on the release association information. According to the above content, in the case that the 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 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, so that stable connection between the terminal side and the network side can be ensured in the case that the 3GPP signal is lost, and stable communication between the terminal side and the network side can still be performed in the case that the 3GPP signal is lost.

[0158] In an embodiment, as Figure 11As shown, a communication connection processing apparatus is provided, configured at a network side, comprising: a second release module 10, wherein:

[0159] The second release module 10 is configured to, in a case where a 3GPP signal is lost at the terminal side and an MPQUIC connection between the terminal side and the network side is maintained, control the terminal side to release the MPQUIC connection based on release association information.

[0160] In an embodiment, the terminal side is sent maintenance indication information; wherein the maintenance indication information is used to instruct the terminal side to maintain the MPQUIC connection with the network side in a case where the 3GPP signal is lost.

[0161] In an embodiment, the terminal side is sent a NAS message; wherein the maintenance indication information is carried in the NAS message.

[0162] In an embodiment, the release association information comprises timing indication information; the timing indication information is used to instruct the terminal side to release the MPQUIC connection in a case where a timing duration of a first timer reaches a set duration.

[0168] The communication connection processing apparatus keeps the MPQUIC connection between the terminal side and the network side in the case where the 3GPP signal is lost at the terminal side, and the network side can release the MPQUIC connection based on the release association information to control the terminal side. According to the above, in the case where the 3GPP signal is lost at the terminal side, the MPQUIC connection between the terminal side and the network side is kept, so that the terminal side is prevented from releasing the MPQUIC connection due to implicit disconnection at the terminal side, and the situation where 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, the situation where the MPQUIC states of the terminal side and the network side are inconsistent is further prevented, and the stable connection between the terminal side and the network side is ensured in the case where the 3GPP signal is lost, so that the terminal side and the network side can still communicate stably in the case where the 3GPP signal is lost.
