Process for real-time data exchange between users on a phone call

A process for real-time data exchange allows for sharing data, including metadata such as user data and phone data, between multiple handsets so that handsets may automatically display such data upon initiation or establishment of a telephone call, and in some arrangements throughout the life of the call. In this way, the need for subsequent data transmissions is reduced or eliminated, making bandwidth usage more efficient and conserving battery power. 种用于实时数据交换的过程，其允许在多个手机之间共享数据，包括诸如用户数据和电话数据之类的元数据，使得手机在发起或建立电话呼叫时、以及在些布置中贯穿呼叫的有效期可以自动显示这样的数据。以这种方式，减少或消除了对随后的数据传输的需要，从而使带宽使用更加高效并节省电池电量。
