Abstract

A method of using subscriber identification information stored in mobile user equipment (UE) to connect to a communication service over a public wireless network in the UE, establishing a communication link between the UE and a device, generating network access information (NAI) associated with the communication service in the UE, and sending the NAI from the UE to the device via the communication link. The method further comprises connecting the communication service in the device using the NAI and terminating the connection of the communication service in the UE.

First claim

What is claimed is:

1. A method enabling connection of at least one communication service over a public wireless network (PWN) by a slave device internally lacking access authorization credentials required to connect to the at least one communication service, the method comprising:
connecting a first communication service in a first master device storing first access authorization credentials;
generating first network status information (1NSI) in the first master device associated with the connecting of the first communication service;
deriving first network accessing information (1NAI) in a first master device from the first access authorization credentials and the 1NSI;
establishing a first communication link between the first master device and slave device;
connecting a second communication service in a second master device storing second access authorization credentials;
generating second network status information (2NSI) in the second master device associated with the connecting of the second communication service;
deriving second network accessing information (2NAI) in the second master device from the second access authorization credentials and the 2NSI;
establishing a second communication link between the second master device and the slave device;
sending the 1NAI from the first master device to the slave device via the first communication link and storing the 1NAI in the slave device;
sending the 2NAI from the second master device to the slave device via the second communication link and storing the 2NAI in the slave device;
connecting the first communication service in the slave device using the 1NAI; and
terminating the first communication service in the first master device.

2. The method of claim 1 , further comprising:
generating updated 1NAI in the slave device during connection of the first communication service in the slave device; and
synchronizing the updated 1NAI between the slave device and the first master device via the first communication link.

3. The method of claim 2 , further comprising:
terminating the second communication service in the second master device;
receiving data in the slave device from the first communication service; and
relaying the data from the slave device to at least two electronic devices including the first master device via the first communication link and the second master device via the second communication link,
wherein the at least two electronic devices and the slave device support using a common communication service over the PWN.

4. The method of claim 1 , further comprising:
connecting the second communication service in the slave device using the 2NAI;
terminating the second communication service in the second master device;
generating updated 2NAI in the slave device during connection of the second communication service in the slave device; and
synchronizing the updated 2NAI between the slave device and the second master device via the second communication link.

5. The method of claim 1 , wherein each one of the first communication link and the second communication link is one of a hard-wired communication link and a wireless communication link.

6. The method of claim 1 , further comprising:
receiving data in the slave device from the first communication service; and
relaying the data from the slave device to the first master device via the first communication link.

7. A method for accessing wireless network, comprising:
using subscriber identification information (SII) stored in a master device to connect a communication service over a public wireless network (PWN) in the master device;
establishing a communication link between the master device and a slave device;
generating network access information (NAI) associated with the communication service in the master device;
sending the NAI from the master device to the slave device via the communication link;
directly connecting the communication service in the slave device over the PWN using the NAI,
after terminating the connection of the communication service in the master device, generating and storing updated NSI in the slave device in accordance with the connection of the communication service in the slave device;
sending the updated NSI to the master device via the communication link; and
updating the NSI stored in the master device with the updated NSI.

8. The method of claim 7 , further comprising:
terminating the connection of the communication service over the PWN in the master device.

9. The method of claim 8 , wherein connecting the communication service in the master device generates corresponding network status information (NSI), and the NAI comprises the NSI, the method further comprising:
storing the NSI in the master device before terminating the connection of the communication service in the master device, and storing the NSI in the slave device when the NAI is sent from the master device to the slave device.

10. The method of claim 9 , wherein the NSI comprises at least one of: PWN cell identification information, radio resource control (RRC) status information, non-access stratum (NAS) status information, and subscriber tracking area (TA) information.

11. The method of claim 8 , wherein the master device is a portable electronic device, the communication service is a cellular voice/data service, and the connecting of the communication service in the master device comprises registering the master device with a mobility management entity (MME) of the PWN.

12. The method of claim 7 , further comprising:
connecting a subscriber identity module (SIM) in the master device, reading the SII from the SIM, and storing the SII in the master device,
wherein the SII comprises a plurality of SII components and the NAI comprises at least one of the plurality of SII components, or information derived from at least one of the plurality of SII components, and
wherein the NAI comprises a temporary mobile subscriber identity (TMSI) provided to the master device from the PWN upon connecting the communication service in the master device.

13. The method of claim 7 , wherein the SII comprises at least one of: a temporary mobile subscriber identity (TMSI), a globally unique temporary identifier (GUTI), an integrated circuit card identification (ICCID), an international mobile subscriber identity (IMSI), and a master key (K).

14. The method of claim 7 , wherein the communication link comprises at least one of local area network (LAN), Wi-Fi, near field communication (NFC), radio frequency (RF), wired communication, a cellular link, Bluetooth (BT), and a global positioning system (GPS).

15. A method enabling connection of a communication service over a public wireless network (PWN) by a slave device internally lacking access authorization credentials required to connect the communication service, the method comprising:
connecting the communication service in a master device storing the access authorization credentials;
generating network status information (NSI) in the master device associated with the connecting of the communication service;
deriving network access information (NAI) in the master device from the access authorization credentials and the NSI;
establishing a communication link between the master device and slave device;
sending the NAI from the master device to the slave device via the communication link;
connecting the communication service in the slave device using the NAI;
terminating the communication service in the master device;
generating updated NAI in the slave device during connection of the communication service in the slave
