摘要： In a headset (14) audio speech signals are picked up by the microphone (25), where they are digitally sampled before being encoded by a vocoder (26). The coded speech data is then provided to a CRC module (27), where error correction data is added before the resulting data is encrypted by an encryption module (22). The resulting encrypted data is transmitting using a Bluetooth radio interface (24), by which the headset is connected wirelessly to a mobile telephone. Received data is decrypted by a decryption module (23), error corrected by an error correction module (28) and decoded by a decoder (29), with the resulting audio signals then being reproduced at a speaker (30). When a user wants to instigate a telephone call with another telephone, the headset (14) is caused to send a control signal to the mobile telephone instructing it to enter a data mode. A data call is then set up and, once established, the CPU (20) controls the setting up of a 128 bit encryption key which is subsequently used for communications between the headset (14) and a corresponding device associated with the recipient of the call. Encryption and decryption are performed only at the headset (14). This provides increased security since even if the call can be intercepted, the interceptor will need to decrypt the signals before being able to reproduce the audio signals.

The coded speech data is then provided to a CRC module 27, where error correction data is added before the resulting data is encrypted by an encryption module 22. The resulting encrypted data is transmitted using a Bluetooth radio interface 24, by which the headset is connected wirelessly to a mobile telephone (Figure 1). Received data is decrypted by a decryption module 23, error corrected by an error correction module 28 and decoded by a decoder 29, with the resulting audio signals then being reproduced at a speaker 30. When a user wants to instigate a telephone call with another telephone, the headset 14 is caused to send a control signal to the mobile telephone instructing it to enter a data mode. A data call is then set up and, once established, the CPU 20 controls the setting up of a 128 bit encryption key which is subsequently used for communications between the headset 14 and a corresponding device associated with the recipient of the call. Encryption and decryption are performed only at the headset 14. This provides increased security since even if the call can be intercepted, the interceptor will need to decrypt the signals before being able to reproduce the audio signals. The encryption key comprises a session key which may be periodically changed by selection of a new key from a catalogue of keys and transmitting the new session key to the recipient in encrypted form.

摘要： A conference call is established in response to receiving a request 4 from a first communication terminal 3a. The request 4 preferably is an SMS or MMS and comprises one or more identifiers 5, 6, 7, e.g. telephone numbers, relating to a plurality of other communication terminals 3b-3d. A conference call server I allocates a conference call channel and an associated identifier, such as a telephone number. Messages 10a-10c alerting the conference participants are then sent to the other communication terminals 3a-3c, each message including the identifier associated with the conference call channel. Access to the conference call may be restricted to authorised users by compating identifiers, such as CLIs, of incoming callers to the identifiers provided in the request 4 and allowing access only if there is a correspondence or match. In the event that an incoming caller has withheld their CLI, or it is otherwise nondeterminable, access is refused and a message may be sent reminding conference participants who have yet to join the conference call not to withhold this information. Alternatively, the server calls the participants at the appropriate time.
摘要翻译：响应于从第一通信终端3a接收到请求4，建立会议呼叫。请求4优选地是SMS或MMS，并且包括一个或多个标识符5,6,7，例如，电话号码，涉及多个其他通信终端3b-3d。电话会议服务器I分配会议电话信道和相关联的标识符，例如电话号码。然后，向会议参与者发送的消息10a-10c被发送到其他通信终端3a-3c，每个消息包括与会议呼叫信道相关联的标识符。电话会议的访问可以通过将来话呼叫者的标识符（诸如CLI）与请求4中提供的标识符进行比较而限制于授权用户，并且仅当存在对应或匹配时才允许访问。如果来电者已经拒绝了他们的CLI，或者其他方式是不可确定的，那么访问被拒绝并且可能会发送一个消息，提醒尚未加入电话会议的会议参与者不要扣留这些信息。或者，服务器在适当的时间呼叫参与者。

摘要翻译：在耳机（14）中，麦克风（25）拾取音频语音信号，其中它们在由声码器（26）编码之前被数字地采样。然后将编码语音数据提供给CRC模块（27），其中在通过加密模块（22）加密所得数据之前添加纠错数据。所得到的加密数据使用蓝牙无线电接口（24）进行传输，通过该接口将头戴式耳机无线连接至移动电话。接收的数据由解密模块（23）解密，由纠错模块（28）纠错并由解码器（29）解码，然后在扬声器（30）再现所得到的音频信号。当用户想要与另一电话发起电话呼叫时，使耳机（14）向移动电话发送控制信号，指示其进入数据模式。然后建立数据呼叫，并且一旦建立，CPU（20）控制设置128位加密密钥，该密钥随后用于耳机（14）和与呼叫接收方相关联的相应设备之间的通信。加密和解密仅在耳机（14）上执行。这提供了更高的安全性，因为即使呼叫可以被拦截，拦截器在能够再现音频信号之前也需要解密信号。
