Abstract

A selective router interface translator for placement between legacy selective routers and their location databases translates location queries from legacy selective router interfaces to newer protocol location databases using newer protocol interfaces, e.g., a NENA V8 protocol query to an Emergency Routing DataBase (ERDB), or a Location to Service Translation (LoST) protocol query to a LoST server. In this way existing selective routers may remain as they are today, yet be flexible enough to allow the databases they query to be developed to new standards. The disclosed selective router interface translator includes a NENA V3 protocol to LoST protocol translator to translate a NENA V3 query for location of an emergency caller into a LoST protocol query. The selective router interface translator also comprises an ALI to ERDB protocol translator to translate an ALI query for location of an emergency caller into an ERDB protocol query.

Claims

1. A selective router interface translator, comprising:

a NENA V3 protocol interface for communication with a location information server (LIS);

a Location to Service Translation (LoST) protocol interface for communication with a LoST server; and

a NENA V3 protocol to LoST protocol translator to translate a NENA V3 query for location of an emergency caller received over said NENA V3 protocol interface into a LoST protocol query for transmission over said LoST protocol interface.

2. The selective router interface translator according to claim 1, further comprising:

an automatic location identifier (ALI) interface for communication with an ALI;

a NENA V8 protocol interface for communication with an Emergency Routing DataBase (ERDB); and

an ALI to ERDB protocol translator to translate an ALI query for location of an emergency caller received over said ALI interface into an ERDB protocol query for transmission over said ERDB interface.

3. The selective router interface translator according to claim 2, wherein said ALI interface comprises:

a NENA E2 protocol format interface.

4. The selective router interface translator according to claim 2, wherein said ALI interface comprises:

a PSAP-to-ALI Message (PAM) protocol format interface.

5. The selective router interface translator according to claim 2, wherein said ALI interface comprises:

a NENA Public Safety Answering Point (PSAP) to ALI protocol format interface.

6. A selective router interface translator, comprising:

an automatic location identifier (ALI) interface for communication with an ALI;

a NENA V8 protocol interface for communication with an Emergency Routing DataBase (ERDB); and

an ALI to ERDB protocol translator to translate an ALI query for location of an emergency caller received over said ALI interface into an ERDB protocol query for transmission over said ERDB interface.

7. The selective router interface translator according to claim 6, wherein said ALI interface comprises:

a NENA E2 protocol format interface.

8. The selective router interface translator according to claim 6, wherein said ALI interface comprises:

a PSAP-to-ALI Message (PAM) protocol format interface.

9. The selective router interface translator according to claim 6, wherein said ALI interface comprises:

a NENA Public Safety Answering Point (PSAP) to ALI protocol format interface.
