Abstract

A method for routing emergency services calls from a subscriber'"'"'s fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP. The method includes: (a) querying a subscriber database using the subscriber'"'"'s calling party identifier, wherein the calling party identifier is one or more of an MSISDN, MDN, Calling Party Address or ANI; (b) determining that the subscriber is associated with a fixed wireless terminal; (c) assigning the subscriber'"'"'s MSISDN as the calling party identifier; (d) assigning Selective Router routing information, wherein the routing information comprises trunk select digits or an ESRN; (e) routing the emergency services call using the assigned Selective Router routing information to the Selective Router and including the MSISDN as the calling party number; and (f) delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN. The method provides routing by “TrunkSelect”+MSISDN and routing by ESRN+MSISDN, in place of the wireless industry-standard “TrunkSelect”+ESRK.

Claims

1. A method for routing emergency services calls from a subscriber'"'"'s fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP;

the method comprising;

(a) querying a subscriber database using the subscriber'"'"'s calling party identifier, wherein the calling party identifier comprises at least one member of the group consisting of;

MSISDN, MDN, Calling Party Address and ANI;

(b) determining that the call is associated with a fixed wireless terminal;

(c) assigning the subscriber'"'"'s MSISDN as the calling party identifier;

(d) assigning Selective Router routing information, wherein the routing information comprises at least one member of the group consisting of;

trunk select digits and ESRN;

(e) routing the emergency services call to the Selective Router based on the routing information including the MSISDN as the calling party; and

(f) delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN.

2. The method of claim 1, wherein the fixed wireless terminal radio technology comprises at least one member of the group consisting of:

GSM, 3G/UMTS;

4G/LTE and CDMA.

3. The method of claim 1, wherein the subscriber database query responds with a class of service indicator, with one indicator value for wireline and a second indicator value for wireless.

4. The method of claim 1, wherein the subscriber database query responds with at least two values, with at least one value for wireline and at least one different value for wireless.

5. The method of claim 1, wherein the subscriber database is coupled to an ALI and the ALI contains a list of fixed wireless subscribers.

6. The method of claim 1, wherein the subscriber database identifies a fixed wireless subscriber as within a range of MSISDNs, with the MSISDN range specified by a start number and an end number.

7. The method of claim 1, wherein the subscriber database identifies a fixed wireless subscriber using an MSISDN pattern.

8. The method of claim 1, wherein the Selective Router routing information is pre-configured based on data associated with an MSC.

9. The method of claim 1, wherein the Selective Router routing information is pre-configured based on data associated with the cell site.

10. A method for adding an ALI record associated with a subscriber'"'"'s fixed wireless terminal and for routing emergency services calls from the fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP;

the method comprising;

(a) querying a subscriber database using the subscriber'"'"'s calling party identifier, wherein the calling party identifier comprises at least one member of the group consisting of;

MSISDN, MDN, Calling Party Address and ANI;

(b) determining that the call is associated with a fixed wireless terminal;

(c) querying an ALI database using the subscriber'"'"'s MSISDN;

(d) determining that an ALI record does not exist for the MSISDN;

(e) submitting an add record request to ALI on behalf of the wireless carrier when no ALI record exists;

(f) assigning the subscriber'"'"'s MSISDN as the calling party identifier;

(g) assigning Selective Router routing information, wherein the routing information comprises at least one member of the group consisting of;

trunk select digits and ESRN;

(h) routing the emergency services call to the Selective Router based on the routing information including the MSISDN as the calling party; and

(i) delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN.

11. The method of claim 10, wherein the fixed wireless terminal radio technology comprises at least one member of the group consisting of:

GSM, 3G/UMTS;

4G/LTE and CDMA.

12. The method of claim 10, wherein the subscriber database query responds with a class of service indicator, with one indicator value for wireline and a second indicator value for wireless.

13. The method of claim 10, wherein the subscriber database query responds with at least two values, with at least one value for wireline and at least one different value for wireless.

14. The method of claim 10, wherein the subscriber database is coupled to an ALI and the ALI contains a list of fixed wireless subscribers.

15. The method of claim 10, wherein the subscriber database identifies a fixed wireless subscriber as within a range of MSISDNs, with the MSISDN range specified by a start number and an end number.

16. The method of claim 10, wherein the subscriber database identifies a fixed wireless subscriber using an MSISDN pattern.

17. The method of claim 10, wherein the Selective Router routing information is pre-configured based on data associated with an MSC.

18. The method of claim 10, wherein the Selective Router routing information is pre-configured based on data associated with the cell site.

19. A system for routing emergency services calls from a subscriber'"'"'s fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP;

the system comprising;

(a) data processing apparatus coupled with a GMLC;

said data processing apparatus being operated such that;

(1) a subscriber database is queried using the subscriber'"'"'s calling party identifier, wherein the calling party identifier comprises at least one member of the group consisting of;

MSISDN, MDN, Calling Party Address and ANI;

(2) a response from the subscriber database query that indicates that the call is associated with a fixed wireless terminal;

(3) the subscriber'"'"'s MSISDN is assigned as the calling party number; and

(4) Selective Router routing information is assigned based on configured data, wherein the routing information comprises at least one member of the group consisting of;

trunk select digits and ESRN;

(c) a switch for routing the emergency services call to a Selective Router based on the routing information provided by the GMLC including the MSISDN as the calling party; and

(d) a Selective Router for delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN.
