具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请 中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统至少包括电子设备01、电子设备02和网络侧设备03，还可以包括其他的电子设备和网络侧设备，图1中仅以无线通信系统包括电子设备01、电子设备02和网络侧设备03为例示出。其中，电子设备01和电子设备02可以通过网络侧设备03进行通话过程。而且，本申请实施例中，电子设备也可以称作终端设备或者用户设备(User Equipment，UE)，电子设备01可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定电子设备的具体类型。网络侧设备03可以是以下至少一项：基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、Wi-Fi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。在本申请实施例中，网络侧设备包括IMS网络设备，以及核心网设备。
目前，相关协议中引入了资源预留(Precondition)机制，为会话发起协议(Session Initiation Protocol，SIP)会话的建立提供了资源保障。在此机制下，被叫端(被叫电子设备)在拿到满足的通话资源时，才会振铃通知用户，从而最大程度的降低了响铃后通话失败的概率。
Precondition机制是引入一组会话建立的限制条件，在限制条件未满足前，被叫电子设备不会振铃，在这些限制条件均满足后，被叫电子设备才能振铃以提醒用户。而限制条件是被叫电子设备是否预留好了通话所需要的资源(带宽、服务保障)等。
通常，SIP会话中使用的Precondition机制，是分段状态类型(segmented status type)，即主被叫两端(主叫电子设备和被叫电子设备)和网络侧设备分别维持自己的会话资源状 态参数，用local表示本端会话资源状态参数(即本端和网络测设备之间的资源状态，后续简称本端)，用remote表示对端的会话资源状态参数(即对端和网络之间的资源状态，后续简称对端)。另外，主叫电子设备发送消息中的local表示主叫电子设备的会话资源状态参数，remote则表示被叫电子设备的会话资源状态参数；被叫电子设备发送消息中的local表示被叫电子设备的会话资源状态参数，remote则表示主叫电子设备的会话资源状态参数。
如图2所示，为一种可能的支持Precondition机制的会话建立过程。其中，第一电子设备为主叫电子设备，也可以简称为Mo端，第二电子设备为被叫电子设备，也可以简称为MT端。具体过程描述如下：
S1：MO端发起邀请(INVITE)消息，INVITE消息中携带本端local和对端remote均为none(指示没有资源)状态。
S2：MT端收到INVITE消息后，发送会话进度(183 Session Progress)消息，183 Session Progress消息中MT本端local为none状态，对端remote也为none状态。
S3：MO端收到183 Session Progress消息后，等待网络侧设备分配通话资源，分配完成后，通过更新(UPDATE)消息更新状态，此时MO端local是sendrecv(指示有收发资源)状态，remote是none状态。
S4：MT端收到UPDATE消息后会答复200 OK消息(表示更新资源状态)，更新资源状态(假定网络侧设备还没有为MT分配通话资源)，此时MT端本端local是none状态，对端remote是sendrecv状态。
S5：MT端网络侧设备分配通话资源后，此时MT端更新状态，本端local是sendrecv状态，对端remote是sendrecv状态，满足Precondition要求，MT端振铃提示用户并发送振铃(180RINGING)消息提示MO端，MT端发送180RINGING消息表示MT端通话资源已经完成预留。
S6：MT端用户接听，发送200 OK消息(此时表示被叫已接听)；
S7：MO端收到200 OK，返回确认(ACK)消息。
针对上述支持Precondition机制的会话建立过程，在第五代移动通信技术(5th-Generation，5G)场景下存在如图3所示的一种情况：S4中MT端发送200 OK消息时，触发5G到4G的切换流程，则有概率(可能)出现MT端发送数据失败或者网络侧设备丢包等问题，导致S4中的200 OK消息未路由到网络侧设备(IMS网络)，则MT端可能在S5后会再次收到网络重传的UPDATE消息(如图中的S3'，消息内容和S3完全一致)，依据相关协议，MT端答复的200 OK也会重传(如图中的S4'，消息内容和S4完全一致，即local none，remote sendrecv)，进而导致网络侧设备认为MT端资源预留没有资源(即没有网络)，网络侧设备不转发MO端和MT端之间的语音，引起MO或MT无法听到对端语音，一段时间后(通常是20s)，网络侧设备挂断MO端和MT端之间的会话，如此，MO端和MT端之间的通话断开。
示例性地，上述支持Precondition机制的会话建立过程中，与MO端和MT端进行会话的网络侧设备(即图2中的网络侧设备)可以为IP多媒体子系统技术(IP Multimedia Subsystem，IMS)网络设备；为MO端和MT端分配通话资源的网络侧设备可以是IMS网络设备和核心网设备(例如IMS网络设备确定通话资源参数，发送给核心网设备，核心网设备为MO端或MT端分配通话资源)。需要说明的是，本申请实施例中，不限定网络侧设备是何种网络设备，具体可以根据实际使用需求确定；网络侧设备的具体实施过程也可以参考相关技术描述，本申请实施例不做限定。
需要说明的是，上面以会话参数为分段状态类型下的会话资源状态参数，会话参数为被叫电子设备的会话参数为例进行说明相关技术存在的技术问题，实际上会话参数为分段状态类型下的会话描述参数，或者会话参数为端对端类型下的会话资源状态参数，或者会话参数为端对端类型下的会话描述参数，第二电子设备为主叫电子设备或被叫电子设备 时，也存在与上述类似的技术问题，具体可以参考相关技术描述，此处不予赘述。
需要说明的是，本申请实施例中会话描述参数为会话描述协议(Session Description Protocol，SDP)中的参数中的至少一种参数，例如可以为SDP中的会话属性参数、编码参数、带宽参数、方向参数等中的至少一种参数，具体可以参考相关技术描述，本申请实施例不做限定。
为了解决上述技术问题，在本申请实施例中，通信设备可以通过在目标通话过程中的会话参数异常的情况下，向第二电子设备发送目标消息，该目标通话为第一电子设备与第二电子设备之间的通话，该会话参数为第二电子设备的会话资源状态参数或会话描述参数，该目标消息用于指示第二电子设备向该通信设备发送目标参数，该目标参数用于该通信设备更新该会话参数。通过该方案，通信设备在会话参数异常的情况下，向第二电子设备发送目标消息(用于指示第二电子设备向该通信设备发送目标参数)，从而根据第二电子设备发送的目标参数更新会话参数，若更新后的会话参数不存在异常，则第一电子设备和第二电子设备之间可以继续进行通话，而无需因通话异常导致通话失败，从而可以降低通话失败的概率。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的会话参数更新方法进行详细地说明。
基于如图1所示的通信系统，本申请实施例提供了一种会话参数更新方法，如图4所示，该会话参数更新方法可以包括下述的步骤101至步骤102。

可选地，本申请实施例中，在目标参数为第二电子设备中保存的第二电子设备只有一种可能(没有其他选择)的参数(例如，会话资源状态参数)时，通信设备可以将会话参数更新为目标参数，即将目标参数作为会话参数。可以理解，在目标参数中仅包括第二电子设备的会话资源状态参数时，通信设备在接收到目标参数之后，将会话参数更新为目标参数。
可选地，本申请实施例中，在目标参数为第二电子设备中保存的第二电子设备有多种 可能的参数(例如，编码参数，第二电子设备支持三种编码参数，分别为自适应多速率编解码(Adaptive Multi-Rate，AMR)、自适应多速率宽带编码(Adaptive Multi-rate-Wideband，AMR-WB)、增强语音服务编码(Enhance Voice Services，EVS))时，通信设备可以将目标参数的部分内容或全部内容更新为会话参数。可以理解，目标参数中可能包括第二电子设备当前使用的编码参数，以及第二电子设备支持的多种编码参数，则通信设备在接收到目标参数之后，可以根据目标参数更新会话参数。

示例性地，在会话参数包括会话资源状态参数和编码参数0时，目标参数为第二电子设备中保存的第二电子设备的资源状态参数，以及第二电子设备支持的三种编码参数，在通信设备接收到目标参数之后，可以根据目标参数更新会话资源状态参数和编码参数。并且，在会话参数更新之后，通信设备还可以向第二电子设备回复携带更新后的会话参数的响应消息。
可选地，本申请实施例中，目标消息可以为通信设备直接询问第二电子设备的目标参数的消息，然后第二电子设备接收到目标消息后，回复包括目标参数的应答消息。

可以理解，Re-INVITE流程和UPDATE流程均是现网已经广泛使用的流程，本申请实施例中可以复用Re-INVITE流程或UPDATE流程，以实现通信设备更新该会话参数。
可以理解，Re-INVITE流程包括以下消息：INVITE消息、100TRYING(可以理解为已收到，正在处理)消息，200 OK消息和ACK消息。对上述消息的具体描述可以参考相关技术，在本申请实施例中，通信设备和第二电子设备可以通过上述消息(INVITE消息、100TRYING消息，200 OK消息和ACK消息)传输目标参数，从而通信设备根据目标参数更新会话参数。
可以理解，UPDATE流程包括以下消息：UPDATE消息和200 OK消息。对上述消息的具体描述可以参考相关技术，在本申请实施例中，通信设备和第二电子设备可以通过上述消息(UPDATE消息和200 OK消息)传输目标参数，从而通信设备根据目标参数更新会话参数。
可选地，本申请实施例中，目标消息可以是目标流程中的消息，也可以不是目标流程中的消息。在目标消息不是目标流程中的消息的情况下，目标消息可以是重新定义的消息，也可以是复用原来的消息，还可以是目标通话建立过程中的消息。
示例性地，在该目标消息用于该通信设备触发与第二电子设备之间的目标流程的情况 下，目标消息可以是目标流程中的消息。例如，针对Re-INVITE流程，目标消息可以为INVITE消息；针对UPDATE流程，目标消息可以为UPDATE消息。

本申请实施例提供的会话参数更新方法，可以在目标通话过程中，如果通信设备检测到会话参数异常，可以再次进行状态同步，避免出现通信设备维持的双方会话参数与实际双方会话参数不一致的问题(例如，通话双方会话资源状态与实际通话双方会话资源状态不一致的问题)，导致网络关闭媒体网关，进而出现通话无声以及通话异常挂断现象。
在本申请实施例中，通信设备可以通过在目标通话过程中的会话参数异常的情况下，向第二电子设备发送目标消息，该目标通话为第一电子设备与第二电子设备之间的通话，该会话参数为第二电子设备的会话资源状态参数或会话描述参数，该目标消息用于指示第二电子设备向该通信设备发送目标参数，该目标参数用于该通信设备更新该会话参数。通过该方案，通信设备在会话参数异常的情况下，向第二电子设备发送目标消息(用于指示第二电子设备向该通信设备发送目标参数)，从而根据第二电子设备发送的目标参数更新会话参数，若更新后的会话参数不存在异常，则第一电子设备和第二电子设备之间可以继续进行通话，而无需因通话异常导致通话失败，从而可以降低通话失败的概率。
下面以会话参数为分段状态类型下、被叫电子设备的会话资源状态参数为例，对本申请实施例提供的会话参数更新方法进行示例性说明。
电子设备注册5G单机(standalone，SA)时，电子设备打电话会从5G核心网回落到4G核心网，SIP流程与5G到4G网络切换流程可能会碰到，易于出现MT端S4步骤200 OKSIP消息发送失败，或者网络转发失败，从而导致如图3所示的典型异常流程。
方案一：网络侧设备触发Re-INVITE流程。
如图5(图中，S4发送失败过程已简化)所示，在通话建立后，网络侧设备(可以为IMS网络设备)新增检查MT端资源预留情况，如果检测到为none，假定不做任何处理，电话会出现无声然后挂断。为了避免此问题场景，故在此阶段，网络侧设备检测到MT会话资源状态参数为none时，则新增S8至S11步骤，以实现MT端会话资源状态参数同步。
如图5所示，S8：网络侧设备向MT发送INVITE消息(从而触发了Re-INVITE流程)，INVITE消息中携带MT端local是none状态，MO端remote为sendrecv状态。S9：MT向网络侧设备发送100TRYING消息，100TRYING消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态，从而网络侧设备可以将其维持的会话资源状态参数更新为MT端和MO端均为sendrecv状态。S10：MT向网络侧设备发送200 OK消息。S11：网络侧设备向MT端发送ACK消息。
本申请实施例中，上述方案一通过新增Re-INVITE流程，在通话建立后检测出异常状态，再次通过SIP消息完成状态同步；Re-INVITE流程现网已经广泛使用，可预见修改的风险较低；此流程上的修改仅涉及到IMS网络，不涉及LTE/5G核心网以及接入网，操作 起来相对容易。
相应地，网络侧设备检测MO端会话资源状态参数同理，如果发现MO端会话资源状态参数异常，同样可以通过上述方案三所述的Re-INVITE流程完成MO端会话资源状态参数同步。具体流程变为：S8：网络侧设备向MO发送INVITE消息(从而触发了Re-INVITE流程)，INVITE消息中携带MO端local是none状态，MT端remote为sendrecv状态。S9:MO向网络侧设备发送100TRYING消息，100TRYING消息中携带MO端local是sendrecv状态，MT端remote为sendrecv状态，从而网络侧设备可以将其维持的会话资源状态参数更新为MT端和MO端均为sendrecv状态。S10:MO向网络侧设备发送200 OK消息。S11：网络侧设备向MO端发送ACK消息。
相应地，网络侧设备检测MT端会话描述参数同理，如果发现MT端会话描述参数异常，同样可以通过上述方案一所述的Re-INVITE流程完成MT端会话描述参数同步。区别为Re-INVITE流程中携带会话描述参数。具体流程变为：S8：网络侧设备向MT发送INVITE消息(从而触发了Re-INVITE流程)，INVITE消息中携带MT端会话描述参数为参数a，MO端会话描述参数为参数b。S9:MT向网络侧设备发送100TRYING消息，100TRYING消息中携带MT端会话描述参数为参数c，MT端会话描述参数为参数b，从而网络侧设备可以将其维持的会话描述参数更新为MO端会话描述参数为参数b，MT端会话描述参数为参数c。S10:MT向网络侧设备发送200 OK消息。S11：网络侧设备向MT端发送ACK消息。
相应地，网络侧设备检测MO端会话描述参数同理，如果发现MO端会话描述参数异常，同样可以通过上述方案一所述的Re-INVITE流程完成MO端会话描述参数同步。具体流程变为：S8：网络侧设备向MO发送INVITE消息(从而触发了Re-INVITE流程)，INVITE消息中携带MO端会话描述参数为参数0，MT端会话描述参数为参数1。S9:MO向网络侧设备发送100TRYING消息，100TRYING消息中携带MO端会话描述参数为参数2，MT端会话描述参数为参数1，从而网络侧设备可以将其维持的会话描述参数更新为MT端会话描述参数为参数1，MO端会话描述参数为参数2。S10:MO向网络侧设备发送200 OK消息。S11：网络侧设备向MO端发送ACK消息。
相应地，对于端到端类型，上述过程类似，可以将对应过程的网络侧设备替换为相应电子设备，例如，MO若为第一电子设备，则MT为第二电子设备；MO若为第二电子设备，则MT为第一电子设备。具体过程可以参考上述过程相关描述，此处不予赘述。
方案二：网络侧设备触发UPDATE流程。
如图6(图中，S4发送失败过程已简化)所示，在通话建立后，网络侧设备(可以为IMS网络设备)新增检查MT端资源预留情况，如果检测到为none，假定不做任何处理，电话会出现无声然后挂断。为了避免此问题场景，故在此阶段，网络侧设备检测到MT会话资源状态参数为none时，则新增S12至S13步骤，通过UPDATE方法更新会话资源状态参数，以实现MT端会话资源状态参数同步。
如图6所示，S12：网络侧设备向MT端发送UPDATE消息，UPDATE消息中携带MT端local是none状态，MO端remote为sendrecv状态。S13：MT端向网络侧设备发送200 OK消息，200 OK消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态。
本申请实施例中，上述方案二通过新增UPDATE流程，在通话建立后检测出异常状态，再次通过SIP消息完成状态同步；UPDATE流程现网已经广泛使用，可预见修改的风险较低；此流程上的修改仅涉及到IMS网络，不涉及LTE/5G核心网以及接入网，操作起来相对容易。
相应地，网络侧设备检测MO端会话资源状态参数同理，如果发现MO端会话资源状态参数异常，同样可以通过上述方案二类似的UPDATE流程完成MO端会话资源状态参 数同步。区别为网络侧设备与MO端交互完成上述UPDATE流程，具体流程可以参考上述方案二中的过程，此处不予赘述。
相应地，网络侧设备检测MT端会话描述参数同理，如果发现MT端会话描述参数异常，同样可以通过上述方案二类似的UPDATE流程完成MT端会话描述参数同步。区别为UPDATE流程中消息携带的为会话描述参数，具体流程可以参考上述方案二中的过程，此处不予赘述。
相应地，网络侧设备检测MO端会话描述参数同理，如果发现MO端会话描述参数异常，同样可以通过上述方案二类似的UPDATE流程完成MO端会话描述参数同步。区别为UPDATE流程中消息携带的为会话描述参数，以及网络侧设备与MO端交互完成上述UPDATE流程。具体流程可以参考上述方案二中的过程，此处不予赘述。
相应地，对于端到端类型，上述过程类似，可以将对应过程的网络侧设备替换为相应电子设备，例如，MO若为第一电子设备，则MT为第二电子设备；MO若为第二电子设备，则MT为第一电子设备。具体过程可以参考上述过程相关描述，此处不予赘述。
方案三：MT端触发Re-INVITE流程。
如图7(图中，S4发送失败过程已简化)所示，类似方案一，网络侧设备在检测到MT端会话资源状态参数为none时，假定不做任何处理，电话会出现无声然后挂断。此时网络侧设备可以通过在通话建立过程中的S7步骤中的ACK消息中携带刷新标识(refresh)，refresh用于指示MT端在通话建立后，触发INVITE流程(如图7中新增S14至S17步骤)，通过刷新会话来实现MT端会话资源状态参数同步。
如图7所示，S14：MT端向网络侧设备发送INVITE消息(从而触发了Re-INVITE流程)，INVITE消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态，从而网络侧设备可以将其维持的会话资源状态参数更新为MT端和MO端均为sendrecv状态。S15：网络侧设备向MT端发送100TRYING消息，100TRYING消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态。S16：网络侧设备向MT端发送200 OK消息。S17：MT端向网络侧设备发送ACK消息。
本申请实施例中，上述方案三网络侧设备识别到异常后，通知MT端进行会话刷新，进一步降低网络侧的改动，网络仅提供一个标识，MT端识别后触发刷新同步动作；通过新增Re-INVITE流程，在通话建立后检测出异常状态，再次通过SIP消息完成状态同步；Re-INVITE流程现网已经广泛使用，可预见修改的风险较低。
相应地，网络侧设备检测MO端会话资源状态参数同理，如果发现MO端会话资源状态参数异常，同样可以通过上述方案三所述的Re-INVITE流程完成MO端会话资源状态参数同步。区别为网络侧设备与MO端交互完成上述Re-INVITE流程，具体流程可以参考上述方案三中的过程，此处不予赘述。
相应地，网络侧设备检测MT端会话描述参数同理，如果发现MT端会话描述参数异常，同样可以通过上述方案三所述的Re-INVITE流程完成MT端会话描述参数同步。区别为Re-INVITE流程中携带会话描述参数，具体流程可以参考上述方案三中的过程，此处不予赘述。
相应地，网络侧设备检测MO端会话描述参数同理，如果发现MO端会话描述参数异常，同样可以通过上述方案三所述的Re-INVITE流程完成MO端会话描述参数同步。区别为Re-INVITE流程中消息携带的为会话描述参数，以及网络侧设备与MO端交互完成上述Re-INVITE流程。具体流程可以参考上述方案三中的过程，此处不予赘述。
相应地，对于端到端类型，上述过程类似，可以将对应过程的网络侧设备替换为相应电子设备，例如，MO若为第一电子设备，则MT为第二电子设备；MO若为第二电子设备，则MT为第一电子设备。具体过程可以参考上述方案三所述的过程的相关描述，此处不予赘述。
方案四：MT触发UPDATE流程。
如图8(图中，S4发送失败过程已简化)所示，类似方案二，网络侧设备在检测到MT端会话资源状态参数为none时，假定不做任何处理，电话会出现无声然后挂断。此时网络侧设备可以通过在通话建立过程中的S7步骤中的ACK消息中携带刷新标识(refresh)，refresh用于指示MT端在通话建立后，触发UPDATE流程(如图8中新增S18至S19步骤)，通过刷新会话来实现MT端会话资源状态参数同步。
如图8所示，S18：MT端向网络侧设备发送UPDATE消息，UPDATE消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态，从而网络侧设备可以将其维持的会话资源状态参数更新为MT端和MO端均为sendrecv状态。S19：网络侧设备向MT端发送200 OK消息，200 OK消息中携带MT端local是sendrecv状态，MO端remote为sendrecv状态。
本申请实施例中，上述方案三网络侧设备识别到异常后，通知MT端进行会话刷新，进一步降低网络侧的改动，网络仅提供一个标识，MT端识别后触发刷新同步动作；通过新增UPDATE流程，在通话建立后检测出异常状态，再次通过SIP消息完成状态同步；UPDATE流程现网已经广泛使用，可预见修改的风险较低。
相应地，网络侧设备检测MO端会话资源状态参数同理，如果发现MO端会话资源状态参数异常，同样可以通过上述方案四类似的UPDATE流程完成MO端会话资源状态参数同步。区别为网络侧设备与MO端交互完成上述UPDATE流程，具体流程可以参考上述方案四中的过程，此处不予赘述。
相应地，网络侧设备检测MT端会话描述参数同理，如果发现MT端会话描述参数异常，同样可以通过上述方案四类似的UPDATE流程完成MT端会话描述参数同步。区别为UPDATE流程中消息携带的为会话描述参数，具体流程可以参考上述方案四中的过程，此处不予赘述。
相应地，网络侧设备检测MO端会话描述参数同理，如果发现MO端会话描述参数异常，同样可以通过上述方案四类似的UPDATE流程完成MO端会话描述参数同步。区别为UPDATE流程中消息携带的为会话描述参数，以及网络侧设备与MO端交互完成上述UPDATE流程。具体流程可以参考上述方案四中的过程，此处不予赘述。
相应地，对于端到端类型，上述过程类似，可以将对应过程的网络侧设备替换为相应电子设备，例如，MO若为第一电子设备，则MT为第二电子设备；MO若为第二电子设备，则MT为第一电子设备。具体过程可以参考上述过程相关描述，此处不予赘述。
