Abstract

Abstract The selective calling and dialling arrangement of a mobile radio station forms radio telegrams addressed to a specific subscriber, interprets received pulse telegrams and controls a radio device and a control device arranged in the mobile radio station. To that end the selective calling and dialling arrangement comprises a first store in which constants identifying a specific country are stored, a program store, a data store and a microprocessor. Commands and system constants are stored in the program store. For subsequent changes in such system constants without the necessity of changing the program stored in the program store, the system constants are stored in a second store, which is connected to the microprocessor via an input/output arrangement.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 125 words
A selective calling and dialling arrangement for a mobile radio station in a radio transmission system, comprising a first store (SP1), a program store (PSP), a data store (DSP), a microprocessor (CPU), and an input/output arrangement (E/A) interconnecting said stores and said microprocessor; wherein said input/output arrangement accesses constants stored in said first store (SP1) and identifying a specific country, and processes these constants in accordance with a program stored in said program store (PSP), characterized in that system constants selected for values for a number of reports to be transmitted, dialling tones, indications, HF and jitter thresholds, number of repetitions or periods for supervision are stored in a second store (SP2) and that the second store (SP2) is connected to the input/output arrangement (E/A).
Claim 2
Dependent Claim 125 words
A selective calling and dialling arrangement for a mobile radio station in a radio transmission system, comprising a first store (SP1), a program store (PSP), a data store (DSP), a microprocessor (CPU), and an input/output arrangement (E/A) interconnecting said stores and said microprocessor; wherein said input/output arrangement accesses constants stored in said first store (SP1) and identifying a specific country, and processes these constants in accordance with a program stored in said program store (PSP), characterized in that system constants selected for values for a number of reports to be transmitted, dialling tones, indications, HF and jitter thresholds, number of repetitions or periods for supervision are stored in a second store (SP2) and that the second store (SP2) is connected to the input/output arrangement (E/A).
Claim 3
Dependent Claim 31 words
A selective calling and dialling arrangement as claimed in claim 1, characterized in that the identification and output characteristics for the mobile radio station are stored in the second store (SP2).
