情况1.判定结果为标识信息#A记录在时钟源列表#A中Case 1. The determination result is that the identification information #A is recorded in the clock source list #A
此情况下，设备#A根据该判定结果，确定该标识信息#A所指示的时钟源#A是已发现的时钟源。In this case, the device #A determines that the clock source #A indicated by the identification information #A is the discovered clock source according to the determination result.
情况2.判定结果为标识信息#A未记录在时钟源列表#A中Case 2. The judgment result is that the identification information #A is not recorded in the clock source list #A
此情况下，设备#A根据该判定结果，确定该标识信息#A所指示的时钟源#A是新发现的时钟源，进而执行S1140。In this case, the device #A determines that the clock source #A indicated by the identification information #A is the newly discovered clock source according to the determination result, and then executes S1140.
具体地说，在S140，设备#A可以获取时钟源#A(或者说，时间同步报文#A)的属性信息。Specifically, in S140, the device #A can obtain the attribute information of the clock source #A (or in other words, the time synchronization message #A).
例如，设备#A可以将该时间同步报文#A(例如，时间同步报文#A携带的时间信息)中携带的时钟域编号、时钟标识或时钟精度等信息作为该时钟源#A的属性信息。For example, device #A can use the clock domain number, clock identifier, or clock accuracy information carried in the time synchronization message #A (for example, the time information carried in the time synchronization message #A) as the attributes of the clock source #A information.
再例如，设备#A可以将时间同步报文#A的接收端口的端口号、设备#A的标识信息或时间同步报文#A所承载于的会话的PDU Session ID作为该时钟源#A的属性信息。For another example, device #A can use the port number of the receiving port of the time synchronization message #A, the identification information of the device #A, or the PDU Session ID of the session carried by the time synchronization message #A as the clock source #A Property information.
并且，设备#A可以直接将该时钟源#A的属性信息发送给SMF。In addition, the device #A can directly send the attribute information of the clock source #A to the SMF.
具体地说，设备#A可以向SMF发送时钟管理消息#A(即，第一信息的一例)，该时钟发现消息#A携带该时钟源#A的属性信息。Specifically, the device #A may send a clock management message #A (that is, an example of the first information) to the SMF, and the clock discovery message #A carries the attribute information of the clock source #A.
在一种实现方式中，该时钟管理消息#A还可以携带该时钟源#A的标识信息。In an implementation manner, the clock management message #A may also carry identification information of the clock source #A.
在另一种实现方式中，该时钟管理消息#A还可以携带新时钟源发现标识(即，第一标识的一例)，新时钟源发现标识用于指示该时钟管理消息#A携带的时钟源为新发现的时钟源，或者说，新时钟源发现标识用于指示该时钟管理消息#A携带的属性信息所属于的时钟源为新发现的时钟源。In another implementation manner, the clock management message #A may also carry a new clock source discovery identifier (that is, an example of the first identifier), and the new clock source discovery identifier is used to indicate the clock source carried in the clock management message #A It is a newly discovered clock source, in other words, the new clock source discovery identifier is used to indicate that the clock source to which the attribute information carried in the clock management message #A belongs is the newly discovered clock source.
需要说明的是，该新时钟源发现标识与后述时钟源过期标识可以共用同一标识位(或者说，比特位)，并且，该新时钟源发现标识与时钟源过期标识对应不同的比特值。It should be noted that the new clock source discovery identifier and the clock source expired identifier described later may share the same identification bit (or bit), and the new clock source discovery identifier and the clock source expired identifier correspond to different bit values.
例如，设该新时钟发现标识对应的比特为“1”，设时钟过期标识对应的比特为“0”。For example, suppose the bit corresponding to the new clock discovery flag is "1", and the bit corresponding to the clock expiration flag is "0".
从而，当设备发现新的时钟源时，可以将该标识位置1；当设备确定时钟源过期时，可以将该标识位置0。Therefore, when the device finds a new clock source, the identification can be set to 1; when the device determines that the clock source is expired, the identification can be set to 0.
从而，SMF可以根据该新时钟源发现标识，确定该时钟管理消息#A内携带的属性信息所属于的时钟源(即时钟源#A)为新发现的时钟源，进而保存时钟源#A的属性信息。Therefore, the SMF can determine the clock source (ie clock source #A) to which the attribute information carried in the clock management message #A belongs according to the new clock source discovery identifier as the newly discovered clock source, and then save the clock source #A Property information.
例如，在确定该时钟源#A的属性信息满足某一业务的需求时，可以进行控制，以使需要访问该业务的终端设备能够接收到该时钟源#A的时间同步报文。For example, when it is determined that the attribute information of the clock source #A meets the requirements of a certain service, control can be performed so that the terminal device that needs to access the service can receive the time synchronization message of the clock source #A.
再例如，SMF可以将该时钟源#A的属性信息发送给NEF，从而NEF可以将该时钟源#A的属性信息作为***的一种时间同步能力能够向外界暴露出去，供第三方应用使用。For another example, the SMF can send the attribute information of the clock source #A to NEF, so that the NEF can expose the attribute information of the clock source #A as a time synchronization capability of the system to the outside for use by third-party applications.
在一种实现方式中，设备#A在判定该标识信息#A所指示的时钟源#A是新发现的时钟源后，可以直接发送该时钟管理消息#A。In an implementation manner, after determining that the clock source #A indicated by the identification information #A is a newly discovered clock source, the device #A may directly send the clock management message #A.

Wherein, the timing duration of the timer #A may be specified by the communication system or communication protocol, or the timing duration of the timer #A may also be set by the administrator device, which is not particularly limited in this application.
并且，设备#A可以判定在该定时器#A到时之前是否再次接受到时钟源#A的时间同步报文。In addition, the device #A can determine whether the time synchronization message of the clock source #A is received again before the timer #A expires.
如果判定结果为是，则设备#A可以发送该时钟管理消息#A。If the result of the determination is yes, the device #A can send the clock management message #A.
如果判定结果为否，则设备#A停止(或者说，禁止或不)发送该时钟管理消息#A。If the result of the determination is negative, the device #A stops (in other words, prohibits or does not) send the clock management message #A.
在另一种实现方式中，在时域上可以划分多个上报周期，假设设备#A在时刻#A接收到该时间同步报文#A，或者，设备#A在时刻#A得到该标识信息#A所指示的时钟源#A是新发现的时钟源的判定结果，则设备#A可以在时刻#A所处于的上报周期发送时钟管理消息#A；或者，设备#A可以在时刻#A所处于的上报周期之后的第T个上报周期发送时钟管理消息#A，其中，T的值大于或等于1，T的值可以由通信协同或通信协议规定，或者，T的值也可以由管理员设备，本申请并未特别限定。In another implementation manner, multiple reporting periods can be divided in the time domain, assuming that device #A receives the time synchronization message #A at time #A, or device #A obtains the identification information at time #A #A指的钟源#A is the result of the determination of the newly discovered clock source, then device #A can send a clock management message #A in the reporting period of time #A; or, device #A can be at time #A The clock management message #A is sent in the Tth reporting period after the reporting period, where the value of T is greater than or equal to 1, and the value of T can be specified by communication coordination or communication protocol, or the value of T can also be managed by Personnel equipment, this application is not particularly limited.

此外，设备#A还可以将时钟源#A的标识信息和属性信息等记录在时钟源列表#A中。In addition, the device #A may also record the identification information and attribute information of the clock source #A in the clock source list #A.
根据本申请的方案，通过在设备#A中配置记录有时钟源的标识信息的时钟源列表，并在时间同步报文内携带该时间同步报文所对应的时钟源的标识信息，从而，设备#A能够根据该时钟源列表，判定所接收到的时间同步报文对应的时钟源是否是新发现的时钟源，进而，能够在判定为是的情况下，可以将该新发现的时钟源的属性信息发送至用于例如，SMF等管理时钟源的网络设备，从而，能够提高时钟源发现的效率，降低时钟源发现的成本和时延。According to the solution of the present application, by configuring a clock source list recording the identification information of the clock source in the device #A, and carrying the identification information of the clock source corresponding to the time synchronization message in the time synchronization message, the device #A According to the list of clock sources, it can be determined whether the clock source corresponding to the received time synchronization message is a newly discovered clock source, and furthermore, if the determination is yes, the newly discovered clock source can be The attribute information is sent to a network device for managing clock sources such as SMF, so that the efficiency of clock source discovery can be improved, and the cost and delay of clock source discovery can be reduced.
