Abstract

A method for exchanging data with a mobile communication network using a group of cloned subscriber identity modules includes: receiving, by the mobile communication network, a first attachment request from a user equipment and/or machine type communication (MTC) device corresponding to a second cloned subscriber identity module; rejecting, by the mobile communication network, the first attachment request based on a user equipment and/or MTC device corresponding to a first cloned subscriber identity module still being attached to the mobile communication network, and transmitting, by the mobile communication network, a waiting time information indicative of a waiting time interval to the user equipment and/or MTC device corresponding to the second cloned subscriber identity module; and receiving, by the mobile communication network, a second attachment request from the user equipment and/or MTC device corresponding to the second cloned subscriber identity module after the waiting time interval has elapsed.

First claim

The invention claimed is:

1. A method for exchanging data with a mobile communication network using a group of cloned subscriber identity modules, wherein the mobile communication network comprises an access network and a core network, wherein the group of cloned subscriber identity modules comprises a plurality of separate subscriber identity modules, each having an assigned International Mobile Subscriber Identity (IMSI) and an assigned Mobile Subscriber Integrated Services Digital Network Number (MSISDN), the assigned IMSI and/or the assigned MSISDN being identical for the subscriber identity modules of the group of cloned subscriber identity modules, wherein the group of cloned subscriber identity modules is associated to a group of user equipments and/or machine type communication (MTC) devices, each of the user equipments and/or MTC devices comprising at least one subscriber identity module of the group of cloned subscriber identity modules, wherein the group of cloned subscriber identity modules comprises a first cloned subscriber identity module and a second cloned subscriber identity module, wherein the method comprises:
in a first step, receiving, by the mobile communication network, a first attachment request from a user equipment and/or MTC device corresponding to the second cloned subscriber identity module;
in a second step, subsequent to the first step, in response to a user equipment and/or MTC device corresponding to the first cloned subscriber identity module still being attached to the mobile communication network:
rejecting, by the mobile communication network, the first attachment request, and
transmitting, by the mobile communication network, a waiting time information indicative of a waiting time interval to the user equipment and/or MTC device corresponding to the second cloned subscriber identity module; and

in a third step, subsequent to the second step, receiving, by the mobile communication network, a second attachment request from the user equipment and/or MTC device corresponding to the second cloned subscriber identity module after the waiting time interval has elapsed.

2. The method according to claim 1 , wherein, in the second step, the waiting time interval is computed such that the waiting time interval is derived from a waiting time constant, the waiting time constant being associated to the group of cloned subscriber identity modules and the waiting time constant corresponding to one out of the following:
a typical attachment time for exchanging a predetermined volume of data between the mobile communication network and a user equipment and/or MTC device comprising a subscriber identity module of the group of cloned subscriber identity modules; or
the sum of, on the one hand, the typical attachment time for exchanging the predetermined volume of data between the mobile communication network and a user equipment and/or MTC device comprising a subscriber identity module of the group of cloned subscriber identity modules, and, on the other hand, an idle time interval.

3. The method according to claim 1 , wherein the group of cloned subscriber identity modules further comprises a third cloned subscriber identity module, and wherein the method further comprises:
in a fourth step, receiving, by the mobile communication network, a further first attachment request from a user equipment and/or MTC device corresponding to the third cloned subscriber identity module while the user equipment and/or MTC device corresponding to the first cloned subscriber identity modules is still attached to the mobile communication network;
in a fifth step, subsequent to the fourth step, rejecting, by the mobile communication network, the further first attachment request and transmitting, by the mobile communication network, a further waiting time information indicative of a further waiting time interval to the user equipment and/or MTC device corresponding to the third cloned subscriber identity module; and
in a sixth step, subsequent to the fifth step, receiving, by the mobile communication network, a further second attachment request from the user equipment and/or MTC device corresponding to the third cloned subscriber identity module after the further waiting time interval has elapsed, wherein the end of the further waiting time interval differs from the end of the waiting time interval.

4. The method according to claim 1 , wherein urgency information is included either in the first attachment request or in the further first attachment request, wherein the urgency information of the respective attachment request is indicative of an urgent need of the respective user equipment and/or MTC device to be attached to the mobile communication network, and wherein the waiting time interval or the further waiting time interval corresponds to:
a waiting time constant decreased by an elapsed time of attachment of the user equipment and/or MTC device corresponding to the first cloned subscriber identity module, or
a typical attachment time for exchanging a predetermined volume of data between the mobile communication network and a user equipment and/or MTC device comprising a subscriber identity module of the group of cloned subscriber identity modules, decreased by the elapsed time of attachment of the user equipment and/or MTC device corresponding to the first cloned subscriber identity module.

5. The method according to claim 1 , wherein the group of cloned subscriber identity modules further comprises a third cloned subscriber identity module, wherein the method further comprises:
receiving, by the mobile communication network, a further first attachment request from a user equipment and/or MTC device corresponding to the third cloned subscriber identity after the user equipment and/or MTC device corresponding to the first cloned subscriber identity module is detached from the mobile communication network but prior to attachment of the user equipment and/or MTC device corresponding to the second cloned subscriber identity module;
accepting, by the mobile communication network, the further first attachment request; and
rejecting, by the mobile communication network, the second attachment request of the user equipment and/or MTC device corresponding to the second cloned subscriber identity module in case that the user equipment and/or MTC device corresponding to the third cloned subscriber identity module is still attached to the mobile communication network, and transmitting, by the mobile communication network, a modified waiting time information to the user equipment and/or MTC device corresponding to the second cloned subscriber identity module.

6. The method according to claim 1 , wherein the mobile communication network exchanges data with the user equipments and/or MTC devices comprising at least one subscriber identity module of the group of cloned subscriber identity modules, wherein the data includes: smart meter related information, intelligent home related information, and/or activation data for at least one additional subscriber identity module per user equipment and/or MTC device.

7. A system for exchanging data between a mobile communication network and user equipments and/or machine type communication (MTC) devices using a group of cloned subscriber identity modules, the system comprising:
the user equipments and/or MTC devices;
the group of cloned subscriber identity modules; and
the mobile communication network, the mobile communication network comprising an access network and a core network;
wherein the group of cloned subscriber identity modules comprises a plurality of separate subscriber identity modules, each having an assigned International Mobile Subscriber Identity (IMSI) and an assigned Mobile Subscriber Integrated Services Digital Network N
