Abstract

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first.

Claims20

Dependent claims

A method of connecting a wireless communication device to a subscriber identification module (SIM) card, wherein the wireless communication device and the SIM card are at different locations, comprising:

a. at the wireless communication device, sending a first request for the SIM card to a SIM card directory server;
b. at the SIM card directory server, selecting the SIM card;
c. at the SIM card directory server, sending a reply corresponding to the first request, wherein the reply includes an identity of the SIM card and an identity of a SIM bank, wherein the SIM bank is in a plurality of SIM banks and holds the SIM card;
d. at the wireless communication device, sending a second request to the SIM bank for a response from the SIM card;
e. at the SIM bank, forwarding the second request to the SIM card;
f. at the SIM bank, forwarding the response to the wireless communication device;
and
g. at the wireless communication device, receiving the response and establishing a wireless connection based on the response;
wherein:
the wireless communication device comprises at least one first network interface;
the SIM card directory server comprises at least one second network interface;
and
each SIM Bank in the plurality of SIM banks comprises at least one third network interface.

10 more elements

A system connecting a wireless communication device to a subscriber identification module (SIM) card, wherein the wireless communication device and the SIM card are at different locations, comprising:

the wireless communication device;
a SIM card directory server;
and
a plurality of SIM banks;
wherein the wireless communication device comprises:
at least one first processing unit;
at least one first non-transitory computer readable storage medium;
and
at least one first network interface;
wherein the SIM card directory server comprises:
at least one second processing unit;
at least one second non-transitory computer readable storage medium;
and
at least one second network interface;
wherein each SIM bank in the plurality of SIM banks comprises:
at least one SIM card;
at least one third processing unit;
at least one third network interface;
and
at least one third non-transitory computer readable storage medium;
wherein the at least one first non-transitory computer readable storage medium stores program instructions executable by the at least one first processing unit and configured to cause the at least one first processing unit to:
send a first request for the SIM card to the SIM card directory server;
send a second request to a SIM bank for a response from the SIM card, wherein the SIM bank is in the plurality of SIM banks and holds the SIM card;
and
receive the response and establish a wireless connection based on the response;
wherein the at least one second non-transitory computer readable storage medium stores program instructions executable by the at least one second processing unit and configured to cause the at least one second processing unit to:
select the SIM card;
and
send the reply corresponding to the first request, wherein the reply includes an identity of the SIM card and an identity of the SIM bank;
and
wherein the at least one third non-transitory computer readable storage medium stores program instructions executable by the at least one third processing unit and configured to cause the at least one third processing unit to:
forward the second request to the SIM card;
and
forward the response to the wireless communication device.
