Abstract

An authentication system is configured to weight multiple available network supplied and user supplied authentication factors to determine whether a user should be provided with access to an Emergency Communication Network (ECN). The multiple factors may include the location of the user, MIN, short PIN, token, biometric information, and other information. The level of access to be provided to the user may be tiered based on the authentication level achieved during the weighting process. Authentication information may be shared between groups of individuals, so that the authentication requirements for group members may be reduced as other members of the group supply authentication information to the ECN. Group authentication may be used to enable group services such as conferencing and push-to-talk to be set up automatically for the group.

Claims

1. A method of authenticating a user of an emergency communication network, the method comprising the steps of:

collecting multiple authentication factors associated with the user, no single factor being sufficient to authenticate the user on the emergency communication network;

applying the multiple authentication factors to a weighted authentication process; and

determining, from the weighted authentication process, a level of access to the emergency communication network be provided to the user.

2. The method of claim 1, wherein the step of applying the multiple authentication factors comprises applying separate weighting factors to each of the collected authentication factors.

3. The method of claim 1, wherein the level of access to the emergency communication network is selected from a plurality of levels of access.

4. The method of claim 3, wherein the plurality of levels of access comprise a no access level and at least two differentiated access levels.

5. The method of claim 1, wherein one of the authentication factors is a short Personal Identification Number (PIN) having no more than six digits.

6. The method of claim 1, wherein none of the authentication factors is a Personal Identification Number (PIN).

7. The method of claim 1, wherein at least one of the authentication factors is derived from the network.

8. The method of claim 1, wherein the authentication factors comprise at least identification information associated with a telephone being used to access the emergency communication network and a location of the user.

9. The method of claim 1, wherein the authentication factors comprise at least one biometric authentication factor.

10. The method of claim 1, wherein the at least one biometric authentication factor comprises at least one of fingerprint information, voice information, and retinal scan information.

11. The method of claim 1, wherein the step of applying the multiple authentication factors to a weighted authentication process comprises weighting the authentication factors according to their reliability.

12. The method of claim 1, further comprising the step of prompting the user for at least one additional authentication factor when the result of the step of determining indicates that the user will not be provided with access to the emergency communication network.

13. A method of enabling in-bound calls to be connected to a first user using resources associated with an emergency communication network, the method comprising the steps of:

receiving, by the emergency communication network, authentication information associated with a first user;

associating, by the emergency communication network, telephone information with the first user;

receiving, by a non-emergency communication network, a setup request indicating that a user of the non-emergency communication network would like to establish a session with the first user; and

enabling the session using at least some of the resources associated with the emergency communication network.

14. A method of authenticating a group of users of an emergency communication network, the method comprising the steps of:

establishing a group association between a plurality of potential users of the emergency communication network;

receiving authentication information from at least one of the potential users of the group association;

authenticating the at least one of the potential users using the authentication information; and

using the authentication information from the at least one of the potential users in connection with authenticating other potential users of the emergency communication network.

15. The method of claim 14, wherein the step of using the authentication information comprises using the authentication information in a weighted authentication process.

16. The method of claim 15, wherein the step of authenticating the at least one of the potential users using the authentication information further comprises enabling access to the emergency communication network for the potential users in the group association without requiring authentication by the other potential users.

17. The method of claim 14, wherein the step of using the authentication information comprises reducing a number of authentication factors required by other potential members to obtain access to the emergency communication network.

18. The method of claim 17, wherein the step of using the authentication information comprises reducing a length of a Personal Identification Number required to be input by the other potential members to obtain access to the emergency communication network.

19. The method of claim 14, further comprising the step of establishing a talk group for members of the group association.

20. The method of claim 19, wherein the step of establishing a talk group for members of the group association enable members of the group to use push-to-talk services to communicate with other members of the group.
