In the embodiment of the application, the network side equipment comprises IMS network equipment and core network equipment.

Currently, a resource reservation (Precondition) mechanism is introduced in the related protocol, and resource guarantee is provided for the establishment of a Session initiation protocol (Session InitiationProtocol, SIP) Session. Under the mechanism, the called terminal (called electronic equipment) can ring to inform the user when the called terminal takes the satisfied call resources, so that the probability of call failure after ringing is reduced to the greatest extent.

The Precondition mechanism is to introduce a set of restrictions for session establishment, the called electronic device will not ring until the restrictions are not satisfied, and the called electronic device will ring to alert the user after the restrictions are satisfied. And the limitation condition is whether the called electronic device reserves the resources (bandwidth, service guarantee) required by the call, etc.

In general, the preconditioning mechanism used in the SIP session is a segment status type (segmented status type), that is, the calling and called ends (calling electronic device and called electronic device) and the network side device respectively maintain their session resource status parameters, and the local session resource status parameters (that is, the resource status between the local end and the network side device, hereinafter referred to as the local end) are represented by local, and the session resource status parameters of the opposite end (that is, the resource status between the opposite end and the network, hereinafter referred to as the opposite end) are represented by remote. In addition, the local in the message sent by the calling electronic device represents the session resource state parameter of the calling electronic device, and the remote represents the session resource state parameter of the called electronic device; the local in the message sent by the called electronic device indicates the session resource status parameter of the called electronic device, and the remote indicates the session resource status parameter of the calling electronic device.

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

s1: the MO initiates an INVITE (INVITE) message, where the INVITE message carries a local state and a remote state of the opposite terminal, which are both none (indicating no resource).

S2: after receiving the INVITE message, the MT sends a Session Progress (183 Session Progress) message, where the local area of the MT in the 183Session Progress message is in the none state, and the remote of the MT is also in the none state.

S3: after receiving 183session progress message, the MO waits for the network side device to allocate call resources, and after allocation is completed, UPDATEs the state by UPDATE message, where the MO local is sendrecv (indicating that there are sending and receiving resources), and remote is none.

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

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

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

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

For the session establishment procedure supporting the Precondition mechanism described above, there is one case as shown in fig. 3 in a fifth Generation mobile communication technology (5 th-Generation, 5G) scenario: when the MT end in S4 sends a 200OK message, a switching process from 5G to 4G is triggered, there is a probability that the MT end fails to send data or the network side device loses packets, so that the 200OK message in S4 is not routed to the network side device (IMS network), the MT end may receive the UPDATE message retransmitted by the network again after S5 (e.g. S3 'in the figure, the message content is completely consistent with S3), the 200OK replied by the MT end is retransmitted according to the relevant protocol (e.g. S4' in the figure, the message content is completely consistent with S4, i.e. local none, remote sender v), and further the network side device considers that the MT end resource reservation has no resource (i.e. no network), the network side device does not forward voice between the MO end and the MT end, so that the MO or MT cannot hear the opposite end voice, after a period of time (typically 20S), the network side device hangs up a session between the MO end and the MT end, so that the call between the MO end and the MT end is disconnected.

Illustratively, in the session establishment procedure supporting the Precondition mechanism, the network-side device (i.e., the network-side device in fig. 2) that performs a session with the MO end and the MT end may be an IP multimedia subsystem (IP Multimedia Subsystem, IMS) network device; the network side device that allocates the session resources for the MO end and the MT end may be an IMS network device and a core network device (e.g., the IMS network device determines session resource parameters and sends the parameters to the core network device, where the core network device allocates the session resources for the MO end or the MT end). It should be noted that, in the embodiment of the present application, the 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 embodiments of the present application are not limited.

It should be noted that, the above description of the related art using the session parameter as the session resource state parameter in the segmentation state type, where the session parameter is the session parameter of the called electronic device, actually the session parameter is the session description parameter in the segmentation 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 when the second electronic device is the calling electronic device or the called electronic device, similar technical problems exist as the above description of the related art, which is specifically omitted herein.

It should be noted that, in the embodiment of the present application, the session description parameter is at least one parameter of parameters in a session description protocol (Session Description Protocol, SDP), for example, may be at least one parameter of session attribute parameters, encoding parameters, bandwidth parameters, direction parameters, etc. in the SDP, and specifically, the embodiment of the present application may be described with reference to related technologies, which is not limited.

In order to solve the above technical problem, in the embodiment of the present application, a communication device may send, to a second electronic device, a target message under a condition that a session parameter in a target session process is abnormal, where the target session is a session between a 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 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 to the second electronic equipment (the target message is used for indicating the second electronic equipment to send the target parameter to the communication 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, conversation can be continued between the first electronic equipment and the second electronic equipment, conversation failure is not required to be caused due to conversation abnormality, and conversation failure probability can be reduced.

The session parameter updating method provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

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

And step 101, under the condition that the session parameters in the target communication process are abnormal, the communication equipment sends a target message to the second electronic equipment.

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 indicating the second electronic device to send the target parameter to the communication device, and the target parameter is used for updating the session parameter by the communication device.

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

The communication equipment is network side equipment or first electronic equipment.

Optionally, in the embodiment of the present application, when the session parameter is a session parameter in a segment status type, the communication device is a network device; the communication device may also be a network side device in other cases, which is not limited by the embodiment of the present application. When the session parameters are the session parameters under the end-to-end type, the communication equipment is the first electronic equipment; the communication device may also be the first electronic device in other cases, which is not limited by the embodiment of the present 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 establishment is completed, specifically may be determined according to actual use requirements, and the embodiment of the present application is not limited.

It may be appreciated that in the embodiment of the present application, the session parameter may include a session resource status parameter (or session description parameter) of the second electronic device stored in the communication device before updating, and the target parameter may include a session resource status parameter (or session description parameter) of the second electronic device stored 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 conversation parameter is updated, the conversation resource state parameter (or conversation description parameter) of the second electronic equipment stored in the communication equipment is the same as the conversation resource state parameter (or conversation description parameter) of the second electronic equipment stored in the second electronic equipment, so that the conversation parameter maintained by the communication equipment is consistent with the actual conversation parameter, the synchronization of the conversation parameter (the conversation resource state parameter synchronization or the conversation description parameter synchronization) is realized, and the conversation can be continued normally without disconnecting the conversation due to the abnormal conversation, thereby causing the conversation failure.

Optionally, in the embodiment of the present 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 the session parameter. It may be appreciated that when the target parameter includes only the session resource status parameter of the second electronic device, the communication device updates the session parameter to the target parameter after receiving the target parameter.

Optionally, in the embodiment of the present application, when the target parameter is a plurality of possible parameters (for example, coding parameters, where the second electronic device supports three coding parameters, that is, adaptive Multi-Rate (AMR), adaptive Multi-Rate-wide-band (AMR-WB), and enhanced voice service coding (Enhance Voice Services, EVS)) of the second electronic device stored in the second electronic device, the communication device may update a part of or all of the content of the target parameter to the session parameter. It may be appreciated that the target parameter may include a coding parameter currently used by the second electronic device and a plurality of coding parameters supported by the second electronic device, and the communication device may update the session parameter according to the target parameter after receiving the target parameter.

For example, when the session parameter is a session resource status parameter, the target parameter is a session resource status parameter of a second electronic device stored in the second electronic device, and after the communication device receives the target parameter, the session parameter may be updated to the target parameter.

For example, the session parameter is a coding parameter 0, the second electronic device sends a target parameter to the communication device, where the target parameter includes a coding parameter 1 currently used by the second electronic device and three voice coding parameters including AMR, AMR-WB and EVS supported by the second electronic device, the communication device may select one voice coding capability (denoted as coding parameter 2) from all supported voice coding capabilities of the second electronic device as a type that both parties will use after negotiation (e.g., the communication device and the second electronic device select AMR-WB to use as a voice coding for a call between both parties), then update the session parameter from the coding parameter 0 to the coding parameter 2, and reply a response message carrying the updated session parameter (coding parameter 2) to the second electronic device.

For example, when the session parameters include a session resource status parameter and an encoding parameter 0, the target parameters are a resource status 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 status parameter and the encoding parameter may be updated according to the target parameters. And after the session parameter is updated, the communication device may also reply to the second electronic device with a response message carrying the updated session parameter.

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

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

Optionally, the target message is used to instruct the second electronic device to trigger a target procedure with the communication device, the target procedure being used by the communication device to update the session parameters.

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

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

It can be understood that the Re-INVITE procedure and the UPDATE procedure are procedures that are already widely used in the current network, and in the embodiment of the present application, the Re-INVITE procedure or the UPDATE procedure can be multiplexed to realize that the communication device UPDATEs the session parameters.

It will be appreciated that the Re-INVITE procedure includes the following messages: INVITE message, 100TRYING (which may be understood as received, processing) message, 200OK message and ACK message. For a specific description of the above message, 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 message (INVITE message, 100 transmission message, 200OK message, and ACK message), so that the communication device updates the session parameter according to the target parameter.

It will be appreciated that the UPDATE flow includes the following messages: UPDATE message and 200OK message. For a specific description of the above message, 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 message (UPDATE message and 200OK message), so that the communication device UPDATEs the session parameter according to the target parameter.

Optionally, in the embodiment of the present application, the target message may be a message in the target flow, or may not be a message in the target flow. In the case that the target message is not a message in the target flow, the target message may be a redefined message, or may be a multiplexed original message, or may be a message in the process of establishing the target call.

For example, in the case where the target message is for the communication device to trigger a target flow with the second electronic device, the target message may be a message in the target flow. For example, for Re-INVITE procedures, the target message may be an INVITE message; for the UPDATE flow, the target message may be an UPDATE message.

For example, in the case where the target message is used to indicate the target flow between the second electronic device trigger and the communication device, the target message may be a message in the target flow, and the target message may be a redefined message or a multiplexed original message.

Optionally, in the embodiment of the present application, in the case that the target message is used to instruct the second electronic device to trigger the target procedure, information for instructing the second electronic device to trigger the target procedure may be carried in the target message.

Optionally, in the case that the target message is used to instruct the second electronic device to trigger the target procedure, the target message carries target information, where the target information is used to instruct the second electronic device to trigger the target procedure.

It may be understood that, in the embodiment of the present application, the target information may be any information capable of indicating the second electronic device to trigger the target flow, the target information may be a refresh identifier, an update identifier, or other identifier, may be indication information, or may be specifically determined according to an actual use requirement, and the embodiment of the present application is not limited.

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

The session parameter updating method provided by the embodiment of the application can carry out state synchronization again if the communication equipment detects that the session parameter is abnormal in the target call process, so that the problem that the session parameters of the two parties maintained by the communication equipment are inconsistent with the session parameters of the two parties in reality (for example, the problem that the session resource states of the two parties in the call are inconsistent with the session resource states of the two parties in the actual call) is avoided, the network closes the media gateway, and further the phenomena of silence of the call and abnormal hanging-up of the call are caused.

The session parameter updating method provided by the embodiment of the application is exemplified by the session resource state parameter of the called electronic device under the condition that the session parameter is taken as the segmentation state type.

Technical problem when an electronic device registers a 5G Stand Alone (SA), an electronic device calls back from a 5G core network to a 4G core network, and the SIP flow and the 5G-to-4G network switching flow may be encountered, so that a MT end S4 step 200OK SIP message transmission failure or a network forwarding failure may easily occur, thereby causing a typical abnormal flow as shown in fig. 3.

Scheme one: the network side equipment triggers Re-INVITE flow.

As shown in fig. 5 (in the figure, the transmission failure process of S4 has been simplified), after the call is established, the network side device (which may be an IMS network device) newly checks the reservation condition of the MT end resource, and if it detects that it is none, it is assumed that no processing is performed, and the phone will appear silent and then hang up. In order to avoid this problem scenario, when the network side device detects that the MT session resource status parameter is none, steps S8 to S11 are newly added to achieve 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 Re-INVITE flow), the INVITE message carries that the local of the MT terminal is in a none state, and the remote of the MO terminal is in a sendrecv state. S9: the MT sends 100TRYING information to the network side equipment, and the 100TRYING information carries that MT end local is sendrecv state and MO end remote is sendrecv state, so that the network side equipment can update session resource state parameters maintained by the MT end local and MO end local are sendrecv states. S10: the MT sends a 200OK message to the network side device. S11: and the network side equipment sends an ACK message to the MT terminal.

In the embodiment of the application, firstly, through the newly added Re-INVITE flow, the abnormal state is detected after the call is established, and the state synchronization is finished through SIP information again; re-INVITE flow is now widely used, and the risk of modification is expected to be low; this modification in flow involves only the IMS network, not the LTE/5G core network and access network, and is relatively easy to operate.

Correspondingly, the network side equipment detects the same condition of the MO end session resource state parameter, and if the MO end session resource state parameter is found to be abnormal, the synchronization of the MO end session resource state parameter can be completed through the Re-INVITE flow described in the third scheme. The specific flow is as follows: s8: the network side equipment sends an INVITE message to the MO (thereby triggering Re-INVITE flow), the INVITE message carries that the MO end local is in a none state, and the MT end remote is in a sendrecv state. And S9, the MO sends a 100TRYING message to the network side equipment, and the 100TRYING message carries that the local of the MO terminal is in a sendrecv state and the remote of the MT terminal is in the sendrecv state, so that the network side equipment can update session resource state parameters maintained by the network side equipment into the sendrecv states of the MT terminal and the MO terminal. And S10, the MO sends a 200OK message to the network equipment. S11: and the network side equipment sends an ACK message to the MO terminal.

Correspondingly, the network side equipment detects the same principle of the MT-side session description parameters, and if the MT-side session description parameters are found to be abnormal, the synchronization of the MT-side session description parameters can be completed through the Re-INVITE flow in the scheme I. The difference is that the Re-INVITE flow carries session description parameters. The specific flow is as follows: s8: the network side equipment sends an INVITE message to the MT (thereby triggering Re-INVITE flow), wherein the INVITE message carries the session description parameter of the MT as parameter a, and the session description parameter of the MO as parameter b. And S9, the MT sends a 100TRYING message to the network side equipment, wherein the 100TRYING message carries the MT-side session description parameter as a parameter c, and the MT-side session description parameter as a parameter b, so that the network side equipment can update the maintained session description parameter as the MO-side session description parameter as the parameter b, and the MT-side session description parameter as the parameter c. S10, the MT sends a 200OK message to the network equipment. S11: and the network side equipment sends an ACK message to the MT terminal.

Correspondingly, the network side equipment detects the same principle of the MO end session description parameter, and if the MO end session description parameter is found to be abnormal, the synchronization of the MO end session description parameter can be completed through the Re-INVITE flow in the scheme I. The specific flow is as follows: s8: the network side equipment sends an INVITE message to the MO (thereby triggering Re-INVITE flow), wherein the INVITE message carries MO-end session description parameter as parameter 0, and mt-end session description parameter as parameter 1. And S9, the MO sends a 100TRYING message to the network side equipment, wherein the 100TRYING message carries the MO end session description parameter as parameter 2, and the MT end session description parameter as parameter 1, so that the network side equipment can update the maintained session description parameter as the MT end session description parameter as parameter 1, and the MO end session description parameter as parameter 2. And S10, the MO sends a 200OK message to the network equipment. S11: and the network side equipment sends an ACK message to the MO terminal.

Correspondingly, for the end-to-end type, the above process is similar, and the network side device of the corresponding process may be replaced by a corresponding electronic device, for example, if the MO is the first electronic device, the MT is the second electronic device; and if the MO is the second electronic equipment, the MT is the first electronic equipment. Specific processes may be referred to the above process related descriptions, and are not repeated here.

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

As shown in fig. 6 (in the figure, the transmission failure process of S4 has been simplified), after the call is established, the network side device (which may be an IMS network device) newly checks the reservation condition of the MT end resource, and if it detects that it is none, it is assumed that no processing is performed, and the phone will appear silent and then hang up. In order to avoid the problem scenario, when the network side device detects that the MT session resource status parameter is none at this stage, steps S12 to S13 are newly added, and the session resource status parameter is updated by the UPDATE method, so as to realize 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 terminal, wherein the UPDATE message carries that the local of the MT terminal is in a none state, and the remote of the MO terminal is in a sendrecv state. S13: the MT end sends a 200OK message to the network side equipment, wherein the 200OK message carries that the local of the MT end is in a sendrecv state, and the remote of the MO end is in the sendrecv state.

In the embodiment of the application, the scheme II detects an abnormal state after the call is established by adding the UPDATE flow, and completes state synchronization again by SIP information; UPDATE procedures are now widely used, with lower risk of foreseeable modifications; this modification in flow involves only the IMS network, not the LTE/5G core network and access network, and is relatively easy to operate.

Correspondingly, the network side equipment detects that the state parameters of the MO end session resources are the same, and if the state parameters of the MO end session resources are found to be abnormal, the synchronization of the state parameters of the MO end session resources can be completed through the similar UPDATE flow of the scheme II. The difference is that the network side device interacts with the MO end to complete the UPDATE flow, and the specific flow may refer to the procedure in the second scheme, which is not described herein.

Correspondingly, the network side equipment detects the same principle of the MT-side session description parameters, and if the MT-side session description parameters are found to be abnormal, the synchronization of the MT-side session description parameters can be completed through the similar UPDATE flow of the scheme II. The difference is that the session description parameter is carried by the message in the UPDATE flow, and the specific flow may refer to the procedure in the second scheme, which is not described herein.

Correspondingly, the network side equipment detects the same principle of the MO end session description parameter, and if the MO end session description parameter is found to be abnormal, the synchronization of the MO end session description parameter can be completed through the similar UPDATE flow of the scheme II. The difference is that the message carried in the UPDATE flow is session description parameters, and the network side equipment interacts with the MO end to complete the UPDATE flow. The specific flow may refer to the procedure in the second scheme, which is not described herein.

As shown in fig. 7 (in the drawing, the transmission failure process of S4 has been simplified), in a similar manner, when the network side device detects that the session resource status parameter of the MT end is none, it is assumed that no processing is performed, and the phone is silent and then hangs up. At this time, the network side device may carry a refresh identifier (refresh) in the ACK message in step S7 in the call establishment procedure, where refresh is used to instruct the MT end to trigger the INVITE procedure after the call is established (as in steps S14 to S17 newly added in fig. 7), and implement session resource state parameter synchronization of the MT end through the refresh session.

As shown in fig. 7, S14: the MT terminal sends an INVITE message to the network side equipment (thereby triggering Re-INVITE flow), the INVITE message carries that the local of the MT terminal is in a sendrecv state, and the remote of the MO terminal is in a sendrecv state, so that the network side equipment can update the session resource state parameters maintained by the network side equipment into the sendrecv state of both the MT terminal and the MO terminal. S15: the network equipment sends 100TRYING information to the MT terminal, the 100TRYING information carries that the local of the MT terminal is in a sendrecv state, and the remote of the MO terminal is in the sendrecv state. S16: the network equipment sends a 200OK message to the MT end. S17: and the MT terminal sends an ACK message to the network side equipment.

In the embodiment of the application, after the equipment at the third network side in the scheme identifies the abnormality, the MT end is informed to carry out session refreshing, the change of the network side is further reduced, the network only provides one identifier, and the MT end triggers refreshing synchronous action after identification; detecting an abnormal state after the call is established through a new Re-INVITE flow, and completing state synchronization through SIP information again; re-INVITE procedures are now widely used and the risk of modification is foreseeable to be low.

Correspondingly, the network side equipment detects the same condition of the MO end session resource state parameter, and if the MO end session resource state parameter is found to be abnormal, the synchronization of the MO end session resource state parameter can be completed through the Re-INVITE flow described in the third scheme. The difference is that the network side device and the MO end interactively complete the Re-INVITE flow, and the specific flow can refer to the process in the third scheme, which is not repeated here.

Correspondingly, the network side equipment detects the same principle of the MT-side session description parameters, and if the MT-side session description parameters are found to be abnormal, the synchronization of the MT-side session description parameters can be completed through the Re-INVITE flow described in the scheme III. The difference is that the Re-INVITE procedure carries session description parameters, and the specific procedure can refer to the procedure in the third scheme, which is not repeated here.

Correspondingly, the network side equipment detects the same principle of the MO end session description parameter, and if the MO end session description parameter is found to be abnormal, the synchronization of the MO end session description parameter can be completed through the Re-INVITE flow described in the scheme III. The difference is that the message carried in the Re-INVITE flow is session description parameter, and the network side equipment and the MO end interactively complete the Re-INVITE flow. The specific flow may refer to the procedure in the third scheme, which is not described herein.

Correspondingly, for the end-to-end type, the above process is similar, and the network side device of the corresponding process may be replaced by a corresponding electronic device, for example, if the MO is the first electronic device, the MT is the second electronic device; and if the MO is the second electronic equipment, the MT is the first electronic equipment. For specific procedures, reference may be made to the description of the procedure described in the third aspect, which is not repeated here.

Scheme IV: MT triggers UPDATE flow.

As shown in fig. 8 (in the drawing, the transmission failure process of S4 has been simplified), similarly to the second scheme, when the network side device detects that the session resource status parameter of the MT end is none, it is assumed that no processing is performed, and the phone 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 step S7 in the call establishment procedure, where refresh is used to instruct the MT end to trigger the UPDATE flow after the call is established (as in steps S18 to S19 in fig. 8), and implement synchronization of session resource state parameters of the MT end through the refresh session.

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