    • Methods and apparatus for increasing security and control of voice communication sessions, such as Push-To-Talk (PTT) over Cellular (PoC) sessions, using digital certificates are disclosed. A certificate control mechanism of a private communication network is used to help facilitate secure PoC sessions for mobile communication devices associated with the private network. The certificate control mechanism of includes a certificate controller which is adapted to communicate with a Certificate Authority (CA) component which produces and stores a plurality of digital certificates for the mobile devices. The certificate controller is further adapted to communicate with one of a PoC server and a PoC group list server through a public communication network (e.g. the Internet) so as to provide the plurality of digital certificates for secure PoC communication sessions for chat groups which include the plurality of mobile communication devices. In one illustrative technique, a request message for participation in a PoC session is received by an authentication component of a PoC server from a mobile device. The request message is signed with use of a private key of a digital certificate which may be associated with the mobile device, an end user of the mobile device, or a chat group which includes the mobile device. An authentication procedure is performed on the request message by the authentication component. The authentication procedure includes retrieving a public key associated with the digital certificate and attempting to validate the signature with use of the public key. Processing for the PoC communication session is permitted for the mobile communication device if the authentication is successful, and otherwise denied. Several other techniques and variations are described.
    • 公开了用于增加语音通信会话的安全性和控制的方法和装置,例如使用数字证书的蜂窝(PoC)会话的一键通(PTT)。 私有通信网络的证书控制机制被用于帮助促进与专用网络相关联的移动通信设备的安全PoC会话。 证书控制机制包括证书控制器,该证书控制器适于与证书颁发机构(CA)组件进行通信,证书颁发机构(CA)组件产生并存储用于移动设备的多个数字证书。 证书控制器还适于通过公共通信网络(例如,因特网)与PoC服务器和PoC组列表服务器之一进行通信,以便为包括以下内容的聊天组提供用于安全的PoC通信会话的多个数字证书 多个移动通信设备。 在一种说明性技术中,用于参与PoC会话的请求消息由移动设备的PoC服务器的认证组件接收。 使用可以与移动设备,移动设备的最终用户或包括移动设备的聊天组相关联的数字证书的私钥对请求消息进行签名。 通过认证组件对请求消息执行认证过程。 认证过程包括检索与数字证书相关联的公开密钥,并尝试使用公钥验证签名。 如果认证成功,则允许用于移动通信设备的PoC通信会话的处理,否则被拒绝。 描述了其他几种技术和变型。

    • There is provided a multi-tap keyboard user interface with auditory feedback. In one embodiment, there is provided a method for controlling operation of a mobile device having a plurality of input devices, comprising associating groups of one or more keys of the input devices to define at least one input region and in response to an input received from said input devices, performing an associated action for operating the device, responding equally to any input from a same input region. A repeated input (multi-tap) to a same input region cycles through a plurality of actions associated with the input region. Auditory feedback comprising a vocalized description of the action is provided. The multi-tap keyboard user interface with auditory feedback may adapt a mobile device (e.g. PDA or smart phone) for use by visually impaired users.
