Abstract: The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection.

Abstract: Exemplary embodiments are directed to operation of a device supporting multiple SIMs. A method may include detecting a paging collision scenario between a first subscription and at least a second subscription. The method may further include modifying a page reading operation of at least one of the first subscription and the at least a second subscription to avoid a paging collision between the first subscription and the at least a second subscription. Other aspects, embodiments, and features are also claimed and described in the application.

Abstract: To reduce the effectiveness of eavesdropping attacks, a filler such as one utilized in a data frame for link-layer LAPDm signaling may be dynamically selected to utilize a first bit pattern (first filler) generated utilizing a first algorithm when the transmissions are unencrypted, and to utilize a second bit pattern (second filler) generated utilizing a second algorithm different from the first algorithm when the transmissions are encrypted.

Abstract: A communications system, and a method suitable for use therein, are described which are suitable for transmitting and receiving both secure and non-secure data. The system comprises: means for transmitting data comprising both ciphered secure data and unciphered non-secure data; means for receiving transmitted data; means for deciphering the received data to produce deciphered data; and means for: validating the deciphered data to produce a first validation result and outputting the deciphered data depending upon the first validation result; or validating the received data to produce a second validation result and outputting the received data depending upon the second validation result; or validating the deciphered data to produce a first validation result and outputting the deciphered data depending upon the first validation result, and also validating the received data to produce a second validation result and outputting the received data depending upon the second validation result.

Abstract: Signals of different cells in a cellular wireless communications system are observed during associated intervals to predict a signal behavior in future. A target cell is selected by observing over time signal characteristics of potential target cells. Thereafter a target cell is selected by using the observed characteristics to predict which potential target cell will in future satisfy certain criteria.
