Abstract: This invention concerns a telecommunication system SYST including: a mobile transmitter/receiver ERM, a number of access points PA1i and PA2j, each capable of communicating with the mobile transmitter/receiver ERM situated in a coverage area ZA1i or ZA2j of the access point considered, and a communication network NW1 authorizing communications between said access points. The system according to the invention includes at least one mobility manager GM capable of determining, based on operating conditions of the access points, with which access point the mobile transmitter/receiver ERM should establish a communication. In the system according to the invention, a change in access point may not be carried out at the sole initiative of a mobile transmitter/receiver ERM, but is, on the contrary, carried out after analysis of an environment specific to said mobile transmitter/receiver ERM by the mobility manager GM.

Abstract: In one embodiment, the present invention is a method and system for calibrating a wireless network including a Mobile Switching Center (MSC), and a Position Determination Device (PDD). The wireless network is capable of determining the position of a handset. The method includes receiving a trigger from the MSC; sending a position request message to the PDD in response to the received trigger; receiving a position request response message from the PDD; continuously sending subsequent position request messages to the PDD in response to the same received trigger, until a termination command is received; terminating the sending subsequent position request messages, when the termination command is received; and generating output data including network calibration parameters.

Abstract: An appearance of other mobile wireless station within a communication area of a second wireless communication system of a main mobile wireless station when the main mobile wireless station is in the communication area of a wireless base station of the first wireless communication system, is automatically detected. Communications with other mobile wireless station are autonomously started by a second wireless communication system and communications with the wireless base station are performed by the first wireless communication system. Communication content from the wireless base station of the first wireless communication system and communication content from the other mobile wireless station of the second wireless communication system are mutually relayed. The relay control is terminated when the other mobile wireless station moves outside the communication area of the second wireless communication system of the main mobile wireless station.

Abstract: In a mobile communications network, a delivery acknowledgement receipt can be sent to indicate a SMS message is delivered. A system can be based on currently-existing protocols, such as described in the IS-136 standard. Existing network signals that acknowledge receipt of a message can be captured and utilized to notify the originator when the SMS message is delivered. A variety of other scenarios (e.g., unsuccessful delivery) can also be supported.

Abstract: Disclosed is a method for simplifying a signal processing process of a base station that receives signals through four branches using two two-branch polarized antennas for each sector. The base station receives signals through first and second branches of the first polarized antenna and third and fourth branches of the second polarized antenna, time-delays the signals received at the second and fourth branches so as to distinguish an offset thereof from an offset of the signals received at the first and third branches, adds the signal received at the first branch and the signal received at the second branch and time-delayed, and adds the signal received at the third branch and the signal received at the fourth branch and time delayed. A modem processor separates an offset distinguishable signal from the added signals.

Abstract: A method for transmitting a signal from a base station transceiver system (BTS) to a base station controller (BSC) when there is no data transmitted from a mobile station while in discontinuous transmission (DTX) mode, in a mobile communication system. Upon detection of the discontinuous transmission mode, it is determined what type of frame was last transmitted from the mobile station, and the present power control information is set according to the type of frame. Thereafter, the base station transceiver system transmits a reverse message including the present power control information to the base station controller over a dedicated control channel. If there is data being transmitted between the mobile station and the base station transceiver system at the time where the discontinuous transmission mode is detected, the previous power control information is set to the present power control information.

Abstract: A method is provided of setting up a call connection to a mobile station operative to communicate with a Customised Application for Mobile Enhanced Logic (CAMEL) telecommunications network. The call is initiated by an Open Service Architecture (OSA) application, which causes a message to be produced which indicates to the network that the mobile station is now available to make a ring back call connection. The network setting up the call connection in response to the message.

Abstract: A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.

Abstract: The details of an apparatus and method of uplink data during cell update in universal mobile telecommunications system user equipment are disclosed herein. According to one aspect of the present application, there is provided a user equipment to send uplink data to a UTRAN during a CELL UPDATE. The apparatus has an uplink data saving RRC with an uplink data store to save the uplink data while the CELL UPDATE procedure is ongoing, and a state machine having a Cell FACH state and/or a Cell DCH state. The uplink data saving RRC sends the saved uplink data to the UTRAN via an UPLINK DIRECT TRANSFER when the CELL UPDATE procedure has completed and the state machine enters either Cell FACH or Cell DCH state. According to another aspect of the present application, there is provided a method of sending uplink data to a UTRAN during a CELL UPDATE procedure.
