Title:
移動通信機器用のサイト依存の一時的なバディー・リスト
Document Type and Number:
Japanese Patent JP4669880
Kind Code:
B2
Abstract:
A system and method of creating a temporary site dependent push-to-talk/media (PTT/M) group for allowing PTT/M communications among a visiting PTT/M equipped mobile device and site based PTT/M equipped devices while the visiting PTT/M equipped mobile device is on-site. An on-site device is responsible for detecting when a visiting PTT/M equipped mobile device comes on-site and initiating a registration process. The registration process registers the visiting PTT/M equipped mobile device with the site based PTT/M equipped devices and the site based PTT/M equipped devices with the visiting PTT/M equipped mobile device such that normal group PTT/M communications can take place. When the visiting PTT/M equipped device leaves the site its absence is detected and a de-registration process is initiated. De-registration removes the recently added device IDs from the site's PTT/M network server and the visiting mobile's PTT/M network server.
