COMMUNICATION MECHANISM FOR CALLS IN WHICH SPEAKING IS NOT POSSIBLE

摘要

In situations in which one or both parties of a call cannot speak on a telephone, a voice call establishment request (5-0) from an calling terminal (A) to a called terminal (B) is processed as follows. The called terminal (B) is alerted and a two-way connection (5-14; 5-24 ... 5-28) is established between the calling terminal (A) and the called terminal (B). In response to determining (3-10; 3-14; 5-8) that a two-way voice call between the calling terminal (A) and the called terminal (B) is not allowed; a mode server (MS, MS') receives silent messages (5-14; 5-24) via a user interface (UI) of the called terminal (B) and conveys (5-14; 5-26 ... 5-28) information based on said silent messages to the calling terminal (A).
