Accessing networks for limited purposes
View Patent ↗One method includes setting up an authenticated communication session between a mobile terminal and a first core data network. The method includes acquiring, at the first core data network, supplementary access data usable by the mobile terminal to set up a non-authenticated communication session with a second data network and then, transmitting the supplementary access data from the first core data network to the mobile terminal. The second data network is accessible to the mobile terminal.
1. A method, comprising:
setting up an authenticated communication session between a mobile terminal and a first core data network;
at the first core data network, acquiring supplementary access data usable by the mobile terminal to set up a non-authenticated communication session with a second data network accessible to the mobile terminal; and
then, transmitting said supplementary access data from the first core data network to the mobile terminal; and
wherein the supplementary access data includes information to set up a locator services communication session for the location of the mobile terminal, an identity of a P-CSCF, an identity of an E-CSCF, an identity of a PSAP, an emergency services routing proxy, or an emergency services routing number.
2. The method of claim 1 , wherein the second data network is an access network or a core data network.
3. The method of claim 1 , wherein the supplementary access data identifies one or more of a data transmission timing, a data frame structure, and a data transmission protocol for the second data network.
4. The method of claim 1 , wherein the supplementary access data includes parameters for accessing the second data network, the parameters being broadcast by the second data network or an access network thereof in a region of the mobile terminal.
5. A method, comprising:
from a first core data network, receiving supplementary access data at a mobile terminal, the supplementary access data enabling a setup of a non-authenticated communication session with a second data network; and
setting up a non-authenticated communication session between the mobile terminal and the second data network by using said received supplementary access data; and
wherein the supplementary access data includes information to set up a locator services communication session for the location of the mobile terminal. an identity of a P-CSCF, an identity of an E-CSCF, an identity of a PSAP, an emergency services routing Proxy, or an emergency services routing number.
6. The method of claim 5 , wherein the second data network is a core data network or an access network.
7. The method of claim 5 , wherein the setting up is performed without passing data from the mobile terminal to the second data network via the first core data network after the receiving step.
8. The method of claim 5 , wherein the non-authenticated communication session includes an emergency call.
9. The method of claim 5 , wherein the setting up step produces a communication session via a second wireless base station or wired access node of the second data network and the supplementary access data is received from a different first wireless base station or access node of the first core data network.
10. The method of claim 5 , wherein the supplementary access data includes information identifying one or more of a data transmission timing, a data frame structure, a security key, and a data transmission protocol for the second data network.
11. The method of claim 5 , wherein the supplementary access data includes parameters for accessing the second data network, the parameters being broadcast by the second data network or an access network thereof in a region of the mobile terminal.
12. An apparatus, comprising:
a portion of a first core data network that includes an information database server and an authentication server;
the portion being configured to set up authenticated communication sessions with a mobile terminal, to acquire supplementary access data usable to set up a non-authenticated communication session with a second data network, and to transmit the supplementary access data to the mobile terminal for use thereby; and
wherein the supplementary access data includes information to set up a locator services communication session for the location of the mobile terminal, an identity of a P-CSCF, an identity of an E-CSCF, an identity of a PSAP, an emergency services routing proxy, or an emergency services routing number.
13. The apparatus of claim 12 , wherein the second data network is a core data network or an access network.
14. The apparatus of claim 12 , wherein the supplementary access data includes parameters for accessing the second data network, the parameters being broadcast by the second data network or an access network thereof in a region of the mobile terminal.
15. The apparatus of claim 12 , wherein the supplementary access data identifies one or more of a data transmission timing, a data frame structure, and a data transmission protocol for the second data network.
16. An apparatus, comprising:
a mobile terminal configured to set up an authenticated communication session with a first core data network and to receive supplementary access data during said session; and
wherein the mobile terminal is configured to use said supplementary access data to set up a non-authenticated communication session with a second data network; and
wherein the supplementary access data includes information for setting up a locator services communication session for the location of the mobile terminal, an identity of a P-CSCF, an identity of an E-CSCF, an identity of a PSAP, an emergency services routing proxy, or an emergency services routing number.
17. The apparatus of claim 16 , wherein the second data network is a core data network or an access network.
18. The apparatus of claim 16 , wherein the said supplementary access data includes access parameters for the second data network, the access parameters being broadcast from an access node of the second data network.
19. The apparatus of claim 16 , wherein the supplementary access data includes information identifying one or more of a data transmission timing, a data frame structure, and a data transmission protocol for the second data network.
20. The apparatus of claim 16 , wherein the mobile terminal is configured to use the supplementary access data to access the second data network via a different communication protocol than the communication protocol used in the authenticated communication session with the first core data network.
