Generic service request signalling is defined where a multimode terminal is allowed to request any service that it supports in any of the modes (e.g., access technology like GERAN/UTRAN/CDMA2000/BlueTooth/WLAN/ . . . ) supported by the terminal. The network may then decide to move the terminal to other system if possible and necessary in order to establish the service. Mostly existing terminal capability indication for each system mode is used.

Generic service request procedure in a multimode system

An E-OTD method for locating a mobile station using measurement information related to arrival of signals transmitted from base stations of different operators for obtaining the base station locations. When one operator does not have enough base stations for providing measurement information for location calculation, the SMLC of that operator acquires measurement information of base stations from at least one other operator using SMLC-SLMC communication protocol.

Method of locating a mobile station based on observed time difference

The invention relates to communication of information in fixed-length messages in mobile communication systems, particularly in association with positioning methods. In a method according to the invention information is transferred in a fixed-length message such that the payload portion of the message includes content information to define the contents of the payload portion of the message, and in accordance with the content information the payload portion of the message includes information elements defined by the content information.

Method for communicating information

A Network Assisted Mobile Terminal GPS system includes a plurality of GPS-capable mobile terminals ( ) each having a transceiver, and a wireless telecommunications network ( ) having at least one base site transceiver ( ) for transmitting GPS Assistance Data to individual ones of the plurality of GPS-capable mobile stations using a point-to-point signalling protocol. In the illustrative embodiment described herein the point-to-point signalling protocol is comprised of at least one of an IMSI (International Mobile Subscriber Identity) Attach, a Normal Location Update, or a Periodic Location Update signalling protocol.
