However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes at least an electronic device 01, an electronic device 02, and a network-side device 03, and may further include other electronic devices and network-side devices, and fig. 1 illustrates only that the wireless communication system includes the electronic device 01, the electronic device 02, and the network-side device 03 as an example. The electronic device 01 and the electronic device 02 may perform a call process through the network-side device 03. In this embodiment, the electronic Device may also be referred to as a terminal Device or a User Equipment (UE), the electronic Device 01 may be a Mobile phone, a tablet Personal Computer (tablet Personal Computer), a Laptop Computer (Laptop Computer) or a terminal-side Device such as a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, an ultra-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and the Wearable Device includes: bracelets, earphones, glasses and the like.

The network-side device 03 may be at least one of: a Base Station or a core network, wherein the Base Station may be referred to as a node B, an evolved node B, an access Point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access Point, a Wi-Fi node, a Transmit Receive Point (TRP), or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present application, only the Base Station in the NR system is taken as an example, but the specific type of the Base Station is not limited. In this embodiment, the network side device includes an IMS network device and a core network device.

At present, a resource reservation (reservation) mechanism is introduced into a related protocol, and a resource guarantee is provided for establishing a Session Initiation Protocol (SIP) Session. Under the mechanism, when the called terminal (called electronic equipment) receives the satisfied call resource, the called terminal rings to inform the user, thereby reducing the probability of call failure after ringing to the maximum extent.

The Precondition mechanism is to introduce a set of restrictions for session establishment, and the called electronic device will not ring until the restrictions are not met, and the called electronic device can ring to remind the user after the restrictions are met. The limiting condition is whether the called electronic device reserves resources (bandwidth, service guarantee) and the like required by the call.

Generally, the Precondition mechanism used in the SIP session is a segmented status type (segmented status type), that is, the calling and called terminals (the calling electronic device and the called electronic device) and the network side device respectively maintain their own session resource status parameters, local session resource status parameters (that is, the resource status between the local terminal and the network side device, which is hereinafter referred to as the local terminal for short) are represented by local, and remote session resource status parameters (that is, the resource status between the remote terminal and the network, which is hereinafter referred to as the remote terminal for short) are represented by remote. In addition, local in the message sent by the calling electronic device represents the session resource state parameter of the calling electronic device, and remote represents the session resource state parameter of the called electronic device; the local in the message sent by the called electronic device represents the session resource status parameter of the called electronic device, and the remote represents the session resource status parameter of the calling electronic device.

As shown in fig. 2, a possible session establishment procedure supporting the Precondition mechanism is shown. The first electronic device is a calling electronic device, which may also be referred to as Mo terminal for short, and the second electronic device is a called electronic device, which may also be referred to as MT terminal for short. The specific process is described as follows:

s1: the MO terminal initiates an INVITE message, wherein the INVITE message carries the states that local and remote terminals are both none (indicating no resources).

S2: after receiving the INVITE message, the MT sends a Session Progress (183Session Progress) message, in which the MT home terminal is in a none state and the remote terminal is also in a none state.

S3: after receiving the 183SessionProgress message, the MO waits for the network side device to allocate call resources, and after the allocation is completed, UPDATEs the state through an UPDATE (UPDATE) message, where local of the MO is a sendrecv (indicating that there are transmission and reception resources) state, and remote is a none state.

S4: after receiving the UPDATE message, the MT replies to the 200OK message (indicating that the resource status is updated), and UPDATEs the resource status (assuming that the network side device has not allocated call resources to the MT), where local at the MT end is a none status, and remote at the opposite end is a sendrecv status.

S5: after the network side equipment of the MT end allocates the call resources, the MT end updates the state at this time, the local end is in the sendrecv state, the remote end is in the sendrecv state, the Precondition requirement is met, the MT end rings to prompt the user and sends a ring (180RINGING) message to prompt the MO end, and the MT end sends a 180RINGING message to indicate that the call resources of the MT end are reserved.

S6: the MT end user answers and sends a 200OK message (at this time, the called party is answered);

s7: and the MO end receives the 200OK and returns an Acknowledgement (ACK) message.

For the session establishment procedure supporting the Precondition mechanism, there is a case as shown in fig. 3 in a fifth Generation mobile communication technology (5th-Generation, 5G) scenario: when the MT sends a 200OK message in S4, a handover procedure from 5G to 4G is triggered, and there is a possibility that (possibly) a problem that the MT fails to send data or the network-side device loses packet, so that the 200OK message in S4 is not routed to the network-side device (IMS network), and then the MT may receive an UPDATE message retransmitted by the network again after S5 (as in S3 'in the figure, the message content is completely consistent with S3), and according to the relevant protocol, the 200OK replied by the MT is also retransmitted (as in S4' in the figure, the message content is completely consistent with S4, i.e., local none and remote sendrecv), so that the network-side device considers that there is no resource reserved by the MT (i.e., there is no network), the network-side device does not forward the voice between the MO and the MT, and thus the MO or the MT cannot hear the opposite-side voice, and after a period of time (usually 20S), the network-side device hangs up the session between the MO and the MT, thus, the call between the MO end and the MT end is disconnected.

For example, in the session establishment process supporting the Precondition mechanism, the network side device (i.e., the network side device in fig. 2) performing a session with the MO end and the MT end may be an IP Multimedia Subsystem (IMS) network device; the network side device that allocates the call resources to the MO end and the MT end may be an IMS network device and a core network device (for example, the IMS network device determines the call resource parameters and sends the call resource parameters to the core network device, and the core network device allocates the call resources to the MO end or the MT end). It should be noted that, in the embodiment of the present application, what network device is not limited, and may be specifically determined according to actual use requirements; the specific implementation process of the network side device may also be described with reference to related technologies, and the embodiments of the present application are not limited.

It should be noted that, the above describes the technical problems in the related art by taking the session parameter as the session resource state parameter in the segmented state type and the session parameter as the session parameter of the called electronic device as an example, and actually, when the session parameter is the session description parameter in the segmented state type, or the session parameter is the session resource state parameter in the end-to-end type, or the session parameter is the session description parameter in the end-to-end type, and the second electronic device is the calling electronic device or the called electronic device, similar technical problems as described above also exist, and reference may be specifically made to the related technical description, which is not repeated herein.

It should be noted that, in the embodiment of the present application, the Session Description parameter is at least one parameter in a Session Description Protocol (SDP), for example, at least one parameter in a Session attribute parameter, a coding parameter, a bandwidth parameter, a direction parameter, and the like in the SDP may be used, and reference may be specifically made to the Description of the related art, which is not limited in the embodiment of the present application.

In order to solve the above technical problem, in this embodiment of the application, the communication device may send a target message to the second electronic device by sending a session parameter to the second electronic device when the session parameter is abnormal during a target call, where the target call is a call between the first electronic device and the second electronic device, the session parameter is a session resource state parameter or a session description parameter of the second electronic device, and the target message is used to instruct the second electronic device to send the target parameter to the communication device, and the target parameter is used for the communication device to update the session parameter. According to the scheme, the communication equipment sends the target message (used for indicating the second electronic equipment to send the target parameter to the communication equipment) to the second electronic equipment under the condition that the conversation parameter is abnormal, so that the conversation parameter is updated according to the target parameter sent by the second electronic equipment, if the updated conversation parameter is not abnormal, the conversation between the first electronic equipment and the second electronic equipment can be continued, the conversation failure caused by the abnormal conversation is not needed, and the probability of the conversation failure can be reduced.

The following describes in detail a session parameter updating method provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Based on the communication system shown in fig. 1, the present application provides a session parameter updating method, which may include steps 101 to 102 described below, as shown in fig. 4.

Step 101, the communication device sends a target message to the second electronic device when the session parameter in the target call process is abnormal.

The target call is a call between the first electronic device and the second electronic device, the session parameter is a session resource state parameter or a session description parameter of the second electronic device, the target message is used for instructing the second electronic device to send a target parameter to the communication device, and the target parameter is used for the communication device to update the session parameter.

Step 102, the second electronic device receives a target message from the communication device.

The communication device is a network side device or a first electronic device.

Optionally, in this embodiment of the present application, when the session parameter is a session parameter in a segment state type, the communication device is a network side device; the communication device may also be a network side device in other cases, which is not limited in this embodiment of the present application. When the session parameter is the session parameter in the end-to-end type, the communication device is a first electronic device; the communication device may also be the first electronic device in other cases, which is not limited in this embodiment of the application.

It can be understood that, in the embodiment of the present application, the target call process may be a target call establishment process, or may be a call process after the target call is established, which may be determined specifically according to an actual use requirement, and the embodiment of the present application is not limited.

It is to be understood that, in the embodiment of the present application, the session parameter may include a session resource state parameter (or session description parameter) of the second electronic device saved in the communication device before the update, and the target parameter may include a session resource state parameter (or session description parameter) of the second electronic device saved in the second electronic device. After the communication device receives the target parameters, the session parameters are updated according to the target parameters. After the session parameter is updated, the session resource state parameter (or session description parameter) of the second electronic device stored in the communication device is the same as the session resource state parameter (or session description parameter) of the second electronic device stored in the second electronic device, so that the session parameter maintained by the communication device is consistent with the actual session parameter, and the synchronization of the session parameter (synchronization of the session resource state parameter or synchronization of the session description parameter) is realized, so that the normal call can be continued without disconnecting the call due to abnormal call, and the call failure is caused.

Optionally, in this embodiment of the application, when the target parameter is only one possible (no other selected) parameter (for example, a session resource status parameter) of the second electronic device stored in the second electronic device, the communication device may update the session parameter to the target parameter, that is, the target parameter is used as the session parameter. It will be appreciated that when only the session resource status parameter of the second electronic device is included in the target parameter, the communication device updates the session parameter to the target parameter after receiving the target parameter.

Optionally, in this embodiment of the application, when the target parameter is a plurality of possible parameters (for example, an encoding parameter, the second electronic device supports three encoding parameters, respectively, Adaptive Multi-Rate (AMR), Adaptive Multi-Rate-Wideband (AMR-WB), enhanced Voice service coding (EVS)) of the second electronic device saved in the second electronic device, the communication device may update a part of or all of the content of the target parameter to be the session parameter. It is to be understood that the target parameters may include an encoding parameter currently used by the second electronic device and a plurality of encoding parameters supported by the second electronic device, and the communication device may update the session parameters according to the target parameters after receiving the target parameters.

Illustratively, when the session parameter is a session resource state parameter, the target parameter is a session resource state parameter of the second electronic device saved in the second electronic device, and after the communication device receives the target parameter, the session parameter may be updated to the target parameter.

Illustratively, the session parameter is coding parameter 0, the second electronic device sends a target parameter to the communication device, the target parameter includes coding parameter 1 currently used by the second electronic device, and the second electronic device supports three speech coding parameters of AMR, AMR-WB, and EVS, the communication device may select one speech coding capability (denoted as coding parameter 2) from all the supported speech coding capabilities of the second electronic device as a type to be used by both (the communication device and the second electronic device) after negotiation (for example, select AMR-WB for speech coding of a double-talk), then update the session parameter from coding parameter 0 to coding parameter 2, and reply a response message carrying the updated session parameter (coding parameter 2) to the second electronic device.

Illustratively, when the session parameters include a session resource state parameter and an encoding parameter 0, the target parameters are a resource state parameter of the second electronic device stored in the second electronic device and three encoding parameters supported by the second electronic device, and after the communication device receives the target parameters, the session resource state parameter and the encoding parameters may be updated according to the target parameters. And after the session parameters are updated, the communication device may also reply to the second electronic device with a response message carrying the updated session parameters.

Optionally, in this embodiment of the application, the target message may be a message in which the communication device directly inquires the target parameter of the second electronic device, and then the second electronic device replies a response message including the target parameter after receiving the target message.

Optionally, the target message is used for the communication device to trigger a target process with the second electronic device, and the target process is used for the communication device to update the session parameter.

Optionally, the target message is used to instruct the second electronic device to trigger a target procedure with the communication device, where the target procedure is used for the communication device to update the session parameter.

Optionally, in this embodiment of the present application, the target process may be a redefined process, or may be a process that is already widely used in a multiplexed current network.

Optionally, the target flow is a Re-INVITE (Re-INVITE) flow or an UPDATE (UPDATE) flow.

It can be understood that both the Re-INVITE flow and the UPDATE flow are widely used in the current network, and in the embodiment of the present application, the Re-INVITE flow or the UPDATE flow may be multiplexed to implement that the communication device UPDATEs the session parameter.

It is understood that the Re-INVITE procedure includes the following messages: INVITE message, 100TRYING (which may be understood as a received, in-process) message, 200OK message, and ACK message. For a detailed description of the above messages, reference may be made to the related art, and in the embodiment of the present application, the communication device and the second electronic device may transmit the target parameter through the above messages (INVITE message, 100TRYING message, 200OK message, and ACK message), so that the communication device updates the session parameter according to the target parameter.

It is understood that the UPDATE flow includes the following messages: UPDATE message and 200OK message. The detailed description of the above messages may refer to the related art, and in the embodiment of the present application, the communication device and the second electronic device may transmit the target parameters through the above messages (UPDATE message and 200OK message), so that the communication device UPDATEs the session parameters according to the target parameters.

Optionally, in this embodiment of the present application, the target message may be a message in a target flow, or may not be a message in a target flow. When the target message is not a message in the target flow, the target message may be a redefined message, may be a multiplexed original message, or may be a message in the target call setup process.

For example, in the case that the target message is for a target flow between the communication device trigger and the second electronic device, the target message may be a message in the target flow. For example, for the Re-INVITE procedure, the target message may be an INVITE message; for an UPDATE flow, the target message may be an UPDATE message.

For example, in the case that the target message is used to instruct the second electronic device to trigger the target process with the communication device, the target message may be a message that is not in the target process, may be a redefined message, or may be a multiplexed original message.

Optionally, in this embodiment of the application, in a case that the target message is used to indicate the second electronic device to trigger the target process, information used to indicate the second electronic device to trigger the target process may be carried in the target message.

Optionally, when the target message is used to instruct the second electronic device to trigger the target process, the target message carries target information, and the target information is used to instruct the second electronic device to trigger the target process.

It can be understood that, in this embodiment of the application, the target information may be any information that can indicate the second electronic device to trigger the target process, the target information may be a refresh identifier, an update identifier, or other identifiers, may be indication information, and the like, and may be specifically determined according to actual use requirements, which is not limited in this embodiment of the application.

Optionally, in a case that the second electronic device is a called electronic device in the target call, the target message is an ACK message in the establishment process of the target call, and the target information is a refresh identifier refresh.

According to the session parameter updating method provided by the embodiment of the application, in the target call process, if the communication equipment detects that the session parameter is abnormal, the state synchronization can be performed again, so that the problem that the session parameters of both parties maintained by the communication equipment are inconsistent with the actual session parameters of both parties (for example, the problem that the session resource states of both parties in the call are inconsistent with the session resource states of both parties in the actual call) is avoided, the network closes the media gateway, and the phenomena of silent call and abnormal call hang-up are caused.

The following takes the session parameter as the session resource state parameter of the called electronic device in the segmented state type as an example, and an exemplary description is given to the session parameter updating method provided in the embodiment of the present application.

Technical problem, when the electronic device registers a 5G stand-alone (SA), the electronic device may call from the 5G core network back to the 4G core network, and the SIP flow and the 5G-to-4G network switching flow may meet each other, which is prone to cause a failure in sending an OK SIP message in step 200 of the MT side S4, or a failure in forwarding the network, thereby resulting in the typical abnormal flow shown in fig. 3.

The first scheme is as follows: and the network side equipment triggers the Re-INVITE flow.

As shown in fig. 5 (in the figure, the S4 sending failure process is simplified), after the call is established, the network side device (which may be an IMS network device) newly checks the MT side resource reservation condition, and if it is detected as none, assuming that no processing is performed, the phone will be silent and then hang up. In order to avoid this problem scenario, at this stage, when the network side device detects that the MT session resource status parameter is none, steps S8 to S11 are added to implement the synchronization of the MT session resource status parameter.

As shown in fig. 5, S8: the network side equipment sends an INVITE message to the MT (thereby triggering the Re-INVITE procedure), the INVITE message carries the MT end local state, and the MO end remote state is sendrecv state. S9: the MT sends a 100TRYING message to the network side device, where the MT local carried in the 100TRYING message is sendrecv state, and the MO remote is sendrecv state, so that the network side device can update the session resource state parameter maintained by the network side device to be sendrecv state at both the MT and MO. S10: the MT sends a 200OK message to the network side equipment. S11: and the network side equipment sends the ACK message to the MT end.

In the embodiment of the application, in the first scheme, an abnormal state is detected after a call is established by newly adding a Re-INVITE flow, and state synchronization is completed through an SIP message again; the Re-INVITE flow is widely used in the existing network, and the risk of foreseeing modification is lower; the modification in the process only relates to the IMS network, and does not relate to the LTE/5G core network and the access network, and the operation is relatively easy.

Correspondingly, the network side device detects the session resource status parameters of the MO end, and similarly, if the session resource status parameters of the MO end are found to be abnormal, the session resource status parameters of the MO end can be synchronized through the Re-INVITE procedure in the third aspect of the above-mentioned scheme. The specific process is as follows: s8: the network side equipment sends an INVITE message to the MO (thereby triggering the Re-INVITE process), the MO local carried in the INVITE message is a none state, and the MT remote is a sendrecv state. S9, the MO sends a 100TRYING message to the network side equipment, the 100TRYING message carries the MO end local state as sendrecv state, the MT end remote state is sendrecv state, and thus the network side equipment can update the session resource state parameters maintained by the network side equipment to be sendrecv state both at the MT end and the MO end. S10, the MO sends 200OK message to the network side device. S11: and the network side equipment sends the ACK message to the MO end.

Correspondingly, the network side device detects the session description parameters of the MT side, and similarly, if the session description parameters of the MT side are found to be abnormal, the session description parameters of the MT side can be synchronized through the Re-INVITE procedure in the first scheme. With the difference that session description parameters are carried in the Re-INVITE flow. The specific process is as follows: s8: the network side equipment sends an INVITE message to the MT (thereby triggering the Re-INVITE procedure), wherein the INVITE message carries the MT end session description parameter as parameter a, and the MO end session description parameter as parameter b. S9, the MT sends a 100TRYING message to the network side equipment, the 100TRYING message carries the MT end session description parameter as parameter c, the MT end session description parameter as parameter b, so that the network side equipment can update the session description parameter maintained by the network side equipment into the MO end session description parameter as parameter b, and the MT end session description parameter as parameter c. S10, the MT sends a 200OK message to the network side equipment. S11: and the network side equipment sends the ACK message to the MT end.

Correspondingly, the network side device detects the MO session description parameters in the same way, and if the MO session description parameters are found to be abnormal, the Re-INVITE procedure in the first scheme can also be used to complete MO session description parameter synchronization. The specific process is as follows: s8: the network side equipment sends an INVITE message to the MO (thereby triggering the Re-INVITE procedure), the session description parameter of the MO end carried in the INVITE message is parameter 0, and the session description parameter of the MT end is parameter 1. S9, the MO sends 100TRYING information to the network side device, the 100TRYING information carries MO end conversation description parameter as parameter 2, the MT end conversation description parameter as parameter 1, thereby the network side device can update the maintained conversation description parameter as MT end conversation description parameter as parameter 1, the MO end conversation description parameter as parameter 2. S10, the MO sends 200OK message to the network side device. S11: and the network side equipment sends the ACK message to the MO end.

Accordingly, for the peer-to-peer type, the above processes are similar, and the network side device corresponding to the process may be replaced with the corresponding electronic device, for example, if the MO is the first electronic device, the MT is the second electronic device; if the MO is the second electronic device, the MT is the first electronic device. For a specific process, reference may be made to the description related to the above process, which is not repeated herein.

Scheme II: the network side device triggers the UPDATE procedure.

As shown in fig. 6 (in the figure, the S4 sending failure process is simplified), after the call is established, the network side device (which may be an IMS network device) newly checks the MT side resource reservation condition, and if it is detected as none, assuming that no processing is performed, the phone will be silent and then hang up. In order to avoid this problem scenario, at this stage, when the network side device detects that the MT session resource status parameter is none, steps S12 to S13 are added, and the session resource status parameter is updated by an UPDATE method, so as to implement synchronization of the MT session resource status parameter.

As shown in fig. 6, S12: the network side equipment sends an UPDATE message to the MT end, wherein the UPDATE message carries the local state of the MT end as a none state, and the remote state of the MO end as a sendrecv state. S13: the MT end sends a 200OK message to the network side equipment, wherein the 200OK message carries the local state of the MT end and the remote state of the MO end is the sendrecv state.

In the embodiment of the application, the two solutions detect an abnormal state after a call is established by adding an UPDATE flow, and complete state synchronization again through an SIP message; the UPDATE flow is widely used in the existing network, and the risk of foreseeing and modifying is lower; the modification in the process only relates to the IMS network, and does not relate to the LTE/5G core network and the access network, and the operation is relatively easy.

Correspondingly, the network side device detects the session resource state parameters of the MO end, and similarly, if the session resource state parameters of the MO end are found to be abnormal, the session resource state parameters of the MO end can be synchronized through the UPDATE procedure similar to the second scheme. The difference is that the network side device and the MO end interactively complete the UPDATE procedure, and the specific procedure may refer to the procedure in the above second scheme, which is not described herein again.

Correspondingly, the network side device detects the session description parameters of the MT side, and similarly, if the session description parameters of the MT side are found to be abnormal, the session description parameters of the MT side can be synchronized through the UPDATE procedure similar to the above-mentioned second scheme. The difference is that the message in the UPDATE flow carries the session description parameters, and the specific flow may refer to the process in the above-mentioned scheme two, which is not described herein again.

Correspondingly, the network side device detects the MO session description parameters in the same way, and if the MO session description parameters are found to be abnormal, the MO session description parameter synchronization can be completed through the UPDATE procedure similar to the above-mentioned second scheme. The difference is that the message in the UPDATE flow carries the session description parameters, and the network side device interacts with the MO end to complete the UPDATE flow. The specific process may refer to the process in the above second scheme, which is not described herein again.

The third scheme is as follows: and the MT end triggers the Re-INVITE flow.

As shown in fig. 7 (in the figure, the S4 failure sending process is simplified), similarly to the first scheme, when the network side device detects that the session resource status parameter of the MT side is a none, it is assumed that no processing is performed, and the telephone will be silent and then hang up. At this time, the network side device may carry a refresh identifier (refresh) in an ACK message in the step S7 in the session establishment process, where refresh is used to indicate that the MT end triggers an INVITE procedure after the session establishment (as new steps S14 to S17 in fig. 7), and implement session resource state parameter synchronization of the MT end by refreshing the session.

As shown in fig. 7, S14: the MT sends an INVITE message to the network side device (thereby triggering the Re-INVITE procedure), where the INVITE message carries the MT local state and the MO remote state, and thus the network side device can update the session resource state parameters maintained by the MT and MO to the sendecv states. S15: the network side equipment sends a 100TRYING message to the MT end, wherein the MT end local carried in the 100TRYING message is sendrecv state, and the MO end remote is sendrecv state. S16: the network side equipment sends a 200OK message to the MT end. S17: and the MT end sends an ACK message to the network side equipment.

In the embodiment of the application, after the network side equipment in the third scheme identifies the abnormality, the network side equipment informs the MT end of session refreshing, so that the change of the network side is further reduced, the network only provides one identifier, and the MT end triggers a refreshing synchronization action after identification; detecting an abnormal state after the call is established by newly adding a Re-INVITE flow, and completing state synchronization through SIP information again; the Re-INVITE procedure is now in wide use with a lower risk of foreseeable modifications.

Correspondingly, the network side device detects the session resource status parameters of the MO end, and similarly, if the session resource status parameters of the MO end are found to be abnormal, the session resource status parameters of the MO end can be synchronized through the Re-INVITE procedure in the third aspect of the above-mentioned scheme. The difference is that the network side device and the MO end interactively complete the Re-INVITE procedure, and the specific procedure may refer to the procedure in the above scheme three, which is not described herein again.

Correspondingly, the network side device detects the session description parameters of the MT side, and if the session description parameters of the MT side are found to be abnormal, the session description parameters of the MT side can be synchronized through the Re-INVITE procedure in the third scheme. The difference is that the Re-INVITE procedure carries session description parameters, and the specific procedure may refer to the procedure in the above-mentioned scheme three, which is not described herein again.

Correspondingly, the network side device detects the MO session description parameters in the same way, and if the MO session description parameters are found to be abnormal, the Re-INVITE procedure in the third scheme can also be used to complete MO session description parameter synchronization. The difference is that the message in the Re-INVITE flow carries session description parameters, and the network side device and the MO end interact to complete the Re-INVITE flow. The specific process may refer to the process in the third scheme, which is not described herein again.

Accordingly, for the peer-to-peer type, the above processes are similar, and the network side device corresponding to the process may be replaced with the corresponding electronic device, for example, if the MO is the first electronic device, the MT is the second electronic device; if the MO is the second electronic device, the MT is the first electronic device. For a specific process, reference may be made to the description related to the process described in the above third scheme, which is not described herein again.

And the scheme is as follows: the MT triggers the UPDATE procedure.

As shown in fig. 8 (in the figure, the S4 sending failure process is simplified), similarly to the second scheme, when the network side device detects that the session resource status parameter of the MT side is a none, it is assumed that no processing is performed, and the telephone will be silent and then hang up. At this time, the network side device may carry a refresh identifier (refresh) in the ACK message in the step S7 in the session establishment process, where the refresh is used to indicate that the MT end triggers an UPDATE procedure after the session establishment (as in the steps S18 to S19 added in fig. 8), and implement session resource state parameter synchronization of the MT end by refreshing the session.

As shown in fig. 8, S18: the MT end sends an UPDATE message to the network side equipment, the UPDATE message carries the local state of the MT end as the sendrecv state, and the remote state of the MO end as the sendrecv state, so that the network side equipment can UPDATE the session resource state parameters maintained by the network side equipment to the sendrecv state of both the MT end and the MO end. S19: the network side equipment sends a 200OK message to the MT, wherein the MT local carried in the 200OK message is sendrecv state, and the MO remote is sendrecv state.

In the embodiment of the application, after the network side equipment in the third scheme identifies the abnormality, the network side equipment informs the MT end of session refreshing, so that the change of the network side is further reduced, the network only provides one identifier, and the MT end triggers a refreshing synchronization action after identification; detecting an abnormal state after the call is established by adding an UPDATE flow, and completing state synchronization through SIP information again; the UPDATE procedure is now widely used in the network, with a lower risk of foreseeable modifications.

Correspondingly, the network side device detects the session resource state parameters of the MO end, and similarly, if the session resource state parameters of the MO end are found to be abnormal, the session resource state parameters of the MO end can be synchronized through the UPDATE procedure similar to the above scheme. The difference is that the network side device and the MO end interactively complete the UPDATE procedure, and the specific procedure may refer to the procedure in the fourth scheme, which is not described herein again.

Correspondingly, the network side device detects the session description parameters of the MT side, and similarly, if the session description parameters of the MT side are found to be abnormal, the session description parameters of the MT side can be synchronized through the UPDATE procedure similar to the above scheme. The difference is that the message in the UPDATE flow carries the session description parameters, and the specific flow may refer to the process in the above-mentioned scheme four, which is not described herein again.

Correspondingly, the network side device detects the MO session description parameters in the same way, and if the MO session description parameters are found to be abnormal, the MO session description parameter synchronization can be completed through the four similar UPDATE flows in the above scheme. The difference is that the message in the UPDATE flow carries the session description parameters, and the network side device interacts with the MO end to complete the UPDATE flow. The specific process may refer to the process in the fourth scheme, which is not described herein again.
