技术领域
本申请属于通感一体化技术领域，具体涉及一种链路监测方法、装置及终端。
背景技术
无线链路监测(Radio link monitoring，RLM)流程主要包括：
1、物理层每隔指示周期(indication period)测量一次基站配置的至少一个无线链路监测参考信号(Radio link monitoring Reference Signal，RLM-RS)以评估对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的接收块误码率(block error rate，BLER)性能；
RLM-RS可以是同步信号和物理广播信道(Synchronization Signal and PBCH block，SSB)信号或者信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或者二者的混合。
2、如果BLER性能低于目标BLER门限如2％，则物理层向高层(无线资源控制(Radio Resource Control，RRC)层)上报同步(In-Sync，IS)；
只要有一个参考信号(Reference Signal，RS)满足条件就上报IS。
3、如果BLER性能高于目标BLER门限如10％，则物理层向高层上报失步(Out-Of-Sync，OOS)；
所有RS都满足条件才上报OOS。
4、如果连续上报OOS的数量超过一个阈值N310，则启动T310计数器。
5、如果在T310计数器运行期间，连续上报的IS数量达到一定的阈值N311，则停止T310计数器(此时仍保持RRC连接)
6、否则，RRC宣告无线链路失败(Radio Link Failure，RLF)，进行RRC重建。
但是目前的无线链路监测流程不适用于通感一体化的场景。
