In one embodiment, the present invention includes a single chip radio tuner, which may be adapted within an integrated circuit (IC). The tuner may be provided with a configurable front end to receive and process a radio frequency (RF) signal via a signal path. This configurable front end may be differently controlled depending on a particular radio implementation in which the tuner is adapted.

A method for indicating a frame mapping way is provided, including: a network side notifying a mobile station of information of a SACCH frame mapping way used by the mobile station. An apparatus for indicating a frame mapping way is further provided, including a determination unit and a notification unit, wherein the determination unit is for determining a used SACCH frame mapping way for a mobile station; the notification unit is for notifying the mobile station of information of a SACCH frame mapping way used by the mobile station. With the invention, the network side can notify the mobile station of the information of which frame mapping way is used determined for the mobile station, thereby solving the problem that the mobile station does not know which frame mapping way is used, greatly improving the performance of the communication system after the mobile station uses the determined frame mapping way.

A method for implementing local call local switch (LCLS) is provided in the present invention, and the method includes that: a mobile switching center (MSC) at a calling side receives a call establishment request of a calling user, and a MSC at a calling side transmits the local reference to a base station system (BSS) at the calling side and a MSC at the called side; the MSC at the called side transmits the received local reference to the BSS at the called side; and a BSS judges whether the local switch can be triggered according to the received local reference, and executes the local switch when determining that the local switch can be triggered. The present invention also provides a system for implementing LCLS. With the method and system provided by the present invention, the problem of unsuccessful local switch resulted by the BSS connecting multiple MSCs is solved.

A process for producing an interface unit and also a group of such interface units are specified. The interface unit exhibits a first reference surface for beaming in radiation, a second reference surface for emitting the radiation, and an axis extending in the direction from the first to the second reference surface. The production process comprises the steps of setting an optical path length of the interface unit between the first and second reference surfaces along the axis and the fixing of the set optical path length of the interface unit. The optical path length of the interface unit is set in such a way that radiation of a defined numerical aperture beamed in at the first reference surface exhibits a focus location that is predetermined with respect to the second reference surface in the direction of the axis. A precise and uniform focus location with respect to the second reference surface is obtained.

The present disclosure relates to the Passive Optical Network (PON) technology, and a method for sending an upstream transfer frame in a PON is provided, so as to improve flexibility of a system and satisfy a requirement that an error probability is reduced as low as possible. The method includes: after success of link, sending a preamble according to an allocated time slot, sending a burst synchronization delimiter, and then sending successively a burst header, a Gigabit-Capable Passive Optical Network (GPON) Transmission Convergence (GTC) frame header, and GTC frame data. In the sent synchronization delimiter, the number of non-zeros is the same as the number of zeros, and in a delimiter sequence, the number of non-zeros on odd bits is equal to the number of zeros on even bits, and the number of non-zeros on even bits is equal to the number of zeros on odd bits.

A mixed signal circuit architecture is disclosed for automatic frequency control and digital temperature compensation in an LC-PLL system. Some embodiments allow for high-volume manufacturing of products such as microprocessors and chipsets, and other circuits that employ LC-PLL technology. In some embodiments, various capacitor loadings can be selected to compensate for variation associated with process, voltage, temperature, and reference frequency. In addition, a multi-leg capacitor bank can be selectively used to further compensate for temperature variation post-lock, in accordance with some embodiments. A programmable timer can be used in some embodiments to allow for loop settling prior to assessing parameters of interest.
