Abstract: Methods of changing a data rate of communication over an interface between a data transmitter and a data receiver are disclosed, wherein the data transmitter is associated with a first processor and transmitting data over the interface and the data receiver is associated with a second processor. The data transmitter transmits and the data receiver receives data over the interface at a first data rate. At the first processor, it is determined to change the first data rate to a second data rate. The data transmitter transmits and the data receiver receives a request to change the first data rate to the second data rate. In response thereto, a response message is transmitted by the data receiver and received by the data transmitter. When the response message comprises an acknowledgement to change the first data rate to the second data rate, the data transmitter transmits and the data receiver receives data over the interface at the second data rate. Corresponding protocol, electronic circuit and electronic device are also enclosed.

Abstract: In a mobile device operative in a packet switched wireless network, the control logic for handling the PS connection resides inside the modem part of the device when dual-stack operation is required (e.g., PDN connections having PDN types IPv4 and IPv6). This effectively hides how dual-stack IPv4v6 connectivity is implemented towards the relevant 3GPP network. Further, the modem always only uses one and only one network interface, as seen from the IP stack, when it operates in dual-stack mode, regardless of how the underlying PDN connection(s) are set up.

Abstract translation: 在分组交换无线网络中操作的移动设备中，当需要双栈操作（例如，具有PDN类型IPv4和IPv6的PDN连接）时，用于处理PS连接的控制逻辑驻留在设备的调制解调器部分内。 这有效地隐藏了如何将双栈IPv4v6连接实现到相关的3GPP网络。 此外，无论底层的PDN连接如何设置，调制解调器总是只使用一个且仅一个网络接口，如IP堆栈所示，当它以双模式运行时。

Abstract: A receiver 10 and method in the receiver for cell search to find an actual base station having a carrier frequency in a radio communications network 1. The receiver detects a first signal representative of a base station 12,14,16,18 by performing slot synchronisation, frame synchronization, cell identification, measurement of a signal quality of the first signal and comparison of the measured signal quality with a first threshold value. When a first signal having a signal quality that is greater than the first threshold value has been detected, the receiver searches for at least one second signal representative of a base station for at least one frequency offset comprised in a set of offsets S3. Further, when one or more second signals are detected, the receiver selects the signal with the highest signal quality, and detects a broadcast radio channel representative of a base station for the selected signal.
