Abstract

The invention relates to both a method and a network entity in a cellular communication network serving mobile terminals or communication devices, offering control over terminals in order to ensure that the best possible data connection is available to the user at all times whatever the coverage scenario and technology the terminals are operating on.

First claim

The invention claimed is:

1. A method in a portable data apparatus for managing data connections in a telecommunication network, the method comprising:
establishing communicative connections with a plurality of mobile terminals that are each operable to establish a data connection in the telecommunication network over a plurality of types of radio access technologies (RATS);
ascertaining which type of RAT at least one of the mobile terminals is camped upon;
controlling connections of each one of the mobile terminals in respective cells of respective RATs; and,
setting a given mobile terminal as operative for establishing a data connection when the given mobile terminal is determined to be camped in a particular RAT.

2. A method according to claim 1 , further comprising establishing a dual connection by means of both first and second mobile terminals of the plurality of terminals.

3. A method according to claim 2 , further comprising aggregating the connections to provide an enhanced data connection.

4. A method according to claim 1 , wherein the portable data apparatus has access to a Radio Network Controller, RNC, of the telecommunication network, the method comprising: accessing the RNC to force terminal connection despite coverage.

5. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a 2G cell, setting a given terminal of the first and second mobile terminals to search for a cell of another RAT.

6. A method according to claim 5 , wherein the another RAT is 3G or LTE.

7. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a 3G cell, setting at least one of the first and second mobile terminals to search for a cell of another RAT.

8. A method according to claim 7 , wherein the another RAT is LTE.

9. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a cell of the same RAT and when both of the first and second mobile terminals are determined to be camped in a particular RAT:
setting the first mobile terminal as operative for establishing a data connection;
determining different available frequency bands of cells of the RAT by instructing the second mobile terminal to looking at neighbouring cells; and,
instructing the second mobile terminal to camp in a cell of the same RAT using an available frequency band different from the frequency band used by the cell in which the first mobile terminal is camped according to frequency band priority defined by the operator.

10. A method according to claim 9 , wherein the RAT is 3G and wherein LTE is unavailable.

11. A method according to claim 9 , further comprising switching the second mobile terminal to a 2G cell and establishing a PDP context if no available frequency band is found.

12. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a cell of the same RAT, setting only the mobile terminal of the first and second mobile terminals having a best coverage level as operative for establishing a data connection when the mobile terminal having the best coverage level is determined to be camped in a preferred RAT.

13. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a cell of a different RAT, setting only the mobile terminal of the first and second mobile terminals with a higher priority RAT as operative for establishing a data connection when the mobile terminal with the higher priority RAT is determined to be camped in a preferred RAT.

14. A method according to claim 1 , further comprising, when both first and second mobile terminals of the plurality of mobile terminals are determined to be camped upon a cell of a different RAT, setting only the mobile terminal of the first and second mobile terminals with a higher TOS operator configurable access technology priority level as operative for establishing a data connection when the mobile terminal with the higher TOS operator configurable access technology priority level is determined to be camped in a preferred RAT.

15. A portable data apparatus for managing data connections in a telecommunication network, the apparatus comprising:
a processor adapted to:
establish communicative connections with a plurality of mobile terminals that are each operable to establish a data connection in the telecommunication network over a plurality of types of radio access technologies (RATs);
ascertain which type of RAT at least one of the mobile terminals is camped upon;
control connections of each one of the mobile terminals in respective cells of respective RATs; and
set a given mobile terminal as operative for establishing a data connection when the given mobile terminal is determined to be camped in a particular RAT.

16. A portable data apparatus according to claim 15 , further comprising a connectivity module adapted to connect terminals to the apparatus, said connectivity module comprising at least one of the following: wireless communication component, short range wireless communication component, cable tether component, USB port, PCMCIA port, firewire port, and Near Field Communication NFC component.
