    • From a directed call graph, local (out, in), (in, in), and (in, out) assortativity coefficients may be calculated. If a phone number's (a) local (out, in) assortativity coefficient > 0; and (b) local (in, in) and (in, out) assortativity coefficients ≤ 0, we may classify the phone number as a spam number. Other parameters measuring the correlation of degrees between linked nodes can be used instead of local assortativity coefficients for phone spam detection. We may use additional conditions, for example, whether the out-degree of a node corresponding a phone number is greater than a threshold, in phone spam detection. We can also use other mechanisms, such as whitelist and blacklist, in phone spam detection.
    • 从定向呼叫图可以计算出本地(out,in),(in,in)和(in,out)分类系数。 如果电话号码(a)本地(out,in)分拣系数> 0; 和(b)本地(in,in)和(in,out)分类系数≤0,我们可以将电话号码分类为垃圾邮件号码。 可以使用测量链接节点之间度数相关性的其他参数,而不是用于电话垃圾邮件检测的本地分类系数。 我们可能会使用额外的条件,例如,在电话垃圾邮件检测中,对应于电话号码的节点的外部程度是否大于阈值。 我们还可以在电话垃圾邮件检测中使用其他机制,例如白名单和黑名单。

    • The embodiments herein relate to call lists that detail all call attempts made to a called party that have not been succesful in communication networks. The reasons for the failure can range from no answer to out of range or congestion in the network. A system and method is disclosed for notifying a called user of a failed call attempt made by a calling user. A switch receives a call request from a calling user and on determining that a communication session cannot be established between the calling user and the called user, the switch terminates the link to the calling user and sends the call attempt notification to the called user. The called user would be notified of the call attempt made by the calling user, the contact details of the calling user and reason for the failure of the call attempt.
    • 这里的实施例涉及详细描述在通信网络中未成功的被叫方进行的所有呼叫尝试的呼叫列表。 失败的原因可以从无应答到超出范围或网络拥塞的范围。 公开了一种系统和方法,用于通知被叫用户呼叫用户进行的失败呼叫尝试。 交换机从主叫用户接收呼叫请求,并且在确定呼叫用户与被叫用户之间不能建立通信会话的情况下,交换机终止与主叫用户的链路,并向被叫用户发送呼叫尝试通知。 被叫用户将被通知主叫用户进行的呼叫尝试,呼叫用户的联系方式以及呼叫尝试失败的原因。
