Handset and method of operation thereof
First Claim
1. A method of establishing a call to a phone using a radiophone which is adapted to communicate via a cellular network and at least one cordless network, said radiophone including a controller and a memory, said method comprising steps of:
- registering in said memory the networks to which the phone is connected, said networks including a cellular network and a cordless network;
storing telephone numbers in said memory;
by means of said controller, automatically checking with numbers stored in said memory prior to the establishment of a call whether a phone number with which the call is to be established contains a main number corresponding to the main number of said at least one cordless network;
determining whether communication is to be via the cellular network or the cordless network based on present location of the radio telephone;
extracting a sequence of digits from the stored numbers of said memory for initiating communication via one of said cellular and said cordless networks; and
in the case of communication via the cordless network, said extracting step comprises determining the extension number of the cordless network if a main number is identified; and
using the extension number of the cordless network when establishing the call via the associated cordless network.

Abstract
A portable radiophone which is adapted to communicate via a cellular network and at least one cordless network, and which comprises a controller unit which controls the communication with said cellular network and said at least one cordless network, and which registers which networks are connected. When a call is to be established, a storage receives a phone number, and the controller unit checks whether the phone number in the storage contains a main number corresponding to the main number of said at least one cordless network. If so, the controller unit determines the extension number of the cordless network for use in the call on the basis of the stored phone number.

5. A method of storing the number of a phone in a memory of a telephone handset which is adapted to communicate via a cellular network and at least one cordless network, said handset including a controller, said method comprising steps of:
-
registering in said memory the networks to which the phone is connected as well as their base numbers and national and regional codes;
by means of said controller, checking prior to the saving of the phone number whether it is a valid extension number to said at least one cordless network and, if so, generating by said controller a PSTN based number on the basis of the extension number and the registered network information;
determining whether communication is to be via the cellular network or the cordless network based on present location of the telephone handset;
extracting a sequence of digits from the stored numbers of said memory for initiating communication via one of said cellular and said cordless networks. - View Dependent Claims (6)

7. A telephone handset which is adapted to communicate via a cellular network and at least one cordless network, comprising:
-
a controller unit which controls the communication with said cellular network and said at least one cordless network, and which registers which networks are connected;
a call storage receiving a phone number in the establishment of a call;
wherein the controller unit, when establishing a call, automatically checks whether the phone number in the call storage contains a main number corresponding to the main number of said at least one cordless network;
wherein the controller unit, if a main number is identified, determines the extension number of the cordless network for use in the call on the basis of the stored phone number; and
wherein the controller unit is operative further to determine whether communication is to be via the cellular network or the cordless network based on present location of the telephone handset, and to extract a number from the call storage for initiating communication via one of said cellular and said cordless networks. - View Dependent Claims (8, 9, 10, 11)

12. A portable radiophone which is adapted to communicate via a cellular network and at least one cordless network, comprising:
-
a controller unit which controls the communication with said cellular network and said at least one cordless network, and which registers which networks are connected;
a memory having a stored phone number list from which a phone number may be obtained when establishing a call;
wherein the controller unit, when storing a phone number in the phone number list, automatically checks whether the number might be an extension number to said at least one cordless network;
wherein the controller unit, if this should be the case, generates a PSTN based number on the basis of the extension number and the registered network information; and
wherein the controller unit is operative further to determine whether communication is to be via the cellular network or the cordless network based on present location of the radiotelephone, and to extract a number from the memory for initiating communication via one of said cellular and said cordless networks. - View Dependent Claims (13)

14. A handset capable of establishing a communication link via respective radio networks using a code indicative of a handset to be reached, said networks including a cellular network and a cordless network, handsets accessible via at least one of the respective networks having a code comprising a first string indicative of a network and a second string indicative of a particular handset in communication with that network, the handset having a preference for establishing a connection via one of the respective networks, the handset comprising:
-
processing means capable of identifying locally available ones of the respective networks;
means for automatically identifying the first string and the second string from a code indicative of a handset to be reached; and
means for establishing a call via the preferred network using only the second string if the first string is indicative of the preferred network; and
wherein the call-establishing means is operative further to determine whether communication is to be via the cellular network or the cordless network based on present location of the handset.

15. A method of establishing a call using a radiophone which is adapted to communicate via a cellular network and at least one cordless network, said radiophone including a controller and a memory, said method comprising steps of:
-
registering in said memory networks to which the phone is connected, said networks including a cellular network and a cordless network;
storing telephone numbers in said memory for phones to be called, the telephone numbers stored in said memory for the phones to be called enabling the radiotelephone to initiate communication with a called phone via a plurality of numbers wherein one of said plurality of numbers establishes communication via the cellular network and a second of said plurality of numbers establishes communication via the cordless network;
determining whether communication is to be via the cellular network or the cordless network based on present location of the radio telephone;
extracting a sequence of digits from the stored numbers of said memory for initiating communication via one of said cellular and said cordless networks; and
in the case of communication via the cordless network, said extracting step comprises, by means of said controller, automatically checking with numbers stored in said memory prior to the establishment of a call whether a phone number with which the call is to be established contains a main number corresponding to the main number of said at least one cordless network.
