System for establishing an outgoing connection from terminal equipment to a data transmission system
First Claim
1. A method for establishing an outgoing connection from terminal equipment to a data transmission system having a base station, wherein a sequence of digits is dialled using the terminal equipment, a connection code in accordance with the dialled sequence of digits is transmitted from the terminal equipment to the base station of the data transmission system, and the data transmission outgoing connection is established on the basis of the transmitted connection code, said method comprising the steps of:
- storing at least one sequence of digits representing a connection code indicative of a previously dialled sequence of digits in memory in the terminal equipment,comparing a dialled sequence of digits during dialling with at least the one sequence of digits stored in the memory of the terminal equipment, andafter the comparing step, transmitting the dialled sequence of digits as a connection code to the base station in accordance with the result of said comparing step to establish an outgoing connection.

Abstract
The objects of the invention are a method for establishing outgoing connections, and a terminal equipment and a data transmission system using the method. The invention is advantageously appicable to wireless local loop (WLL) systems. According to the invention, upon selection of a connection code consisting of a sequence of digits, the dialled digits are monitored (103) and it is checked (105, 107) whether the sequence of digits consisting of the dialled digits is identical with any one of the connection coded dialled last. If the sequence of digits is identical with any one of the connection codes dialled last, and especially, if an outgoing connection has already previously been established using this sequence, it is known that the connection code contains no more digits, and thus the sequence of digits is transmitted (109) to the base station for establishment of the connection. In case the dialled sequence of digits is not idential with any one of the connection codes dialled last, the terminal equipment waits (103, 121) for the dialling of the next digit for a predetermined time, and if no next digit is dialled within this time, the terminal equipment transmits (109) the sequence of digits consisting of the dialled digits to the base station as the connection code for establishing an outgoing connection. A list of the connection codes dialled last is contained in the memory of the terminal equipment so that the dialled sequence of digits can be compared with these.

13. A data transmission system including at least one terminal equipment having a stored connection code and comprising at least one base station with a connection going out from the terminal equipment to the base station being established on the basis of a connection code, when the connection code is selected by being dialled in the terminal equipment, and the selected connection code is transmitted from the terminal equipment to the base station, wherein the improvement comprises:
-
means for storing at least one connection code in the form of a sequence of digits indicative of a previously dialled sequence of digits, in the terminal equipment of the data transmission system, means for comparing a dialled sequence of digits during dialling with at least the one connection code stored in the terminal equipment to determine if the dialled sequence of digits is a selected connection code and producing a result of the comparison, and means, responsive to a result of a comparison produced by said comparing means, for transmitting the selected dialled sequence of digits as a connection code from the terminal equipment to the base station in accordance with the result of the comparison by said comparing means. - View Dependent Claims (18, 19, 20)
