Definitions
- This invention relates generally to wireless telecommunication. More particularly, it relates to the delivery of location information to PSAP/ALI systems in a non-landline environment i.e. cellular, VoIP etc in an emergency services call flow.
- 9-1-1 is a phone number widely recognized in North America as an emergency phone number that is used to contact emergency dispatch personnel.
- Enhanced 9-1-1 (E9-1-1) is defined by the transmission of callback number and location information when 9-1-1 is used.
- E9-1-1 may be implemented for landline, cellular or VoIP networks.
- a Public Service Answering Point (PSAP) is a dispatch office that receives 9-1-1 calls from the public.
- PSAP may be a local, fire or police department, an ambulance service or a regional office covering all services.
- a 9-1-1 service becomes E-9-1-1 when automatic number identification and automatic location information related to the call is provided to the 9-1-1 operator at the PSAP.
- a primary challenge results from the fact that calls may arrive at the PSAP without callback number or location information displayed at the emergency operators terminal.
- a PSAP is connected to one Automatic Location Identifier (ALI).
- ALI is a database that accepts a PSAP query with telephone number, relates the telephone number to an address and provides that address (location information) back to the PSAP in a manner that works for the customer premise equipment (CPE) display.
- An ALI is typically owned by a LEC or a PSAP, and may be regional (i.e. connected to many PSAPs) or standalone (i.e. connected to only one PSAP). There is no one single standard interface protocol for PSAP-ALI connection/communication.
- PSAPs are publicly funded and maintain only one outside ALI connection for both landline and non-landline networks. Some ALIs are able to support only one outside connection to a positioning center. This is problematic for non-landline networks, which have users who are inherently mobile and may be in a particular PSAP-ALI jurisdiction, but their provider does not maintain a connection to the PSAP/ALI.
- FIG. 7 shows a conventional landline public safety access point (PSAP) to automatic location identifier (ALI) connection.
- PSAP public safety access point
- ALI automatic location identifier
- the PSAP upon receiving a 9-1-1 call, queries their ALI for location data.
- an ALI 401 accepts a PSAP 400 query for location and returns location based on pre-provisioned data for the telephone number.
- FIG. 8 shows a context diagram for a conventional non-landline XPC network.
- PSAPs 400 a, 400 b query the same ALI 401 a, 401 b for location information.
- the ALI 401 a, 401 b is not pre-provisioned with location data for non-landline calls (e.g. cellular, VoIP etc) and must communicate with other network entities to obtain and deliver location data to the PSAP 400 a, 400 b.
- Non-landline telephony standards e.g. cellular, VoIP etc
- ALIs 401 , 401 a, 401 b maintain connectivity to positioning centers 402 a, 402 b, 402 c that are able to provide current location data for a non-landline call.
- the positioning center 402 provides the caller's location and the callback number to the ALI, which passes it to the requesting PSAP.
- an ALI may maintain connectivity to more than one positioning center via an multiple interface types 403 a, 403 b, 403 c, . . . , etc.—both standard and non-standard (e.g. NENA ESP, PAM, E2+ etc).
- XPC refers interchangeably to any standards-based positioning center.
- a positioning center 402 may be any one of the following types used in non-landline networks:
- GMLC Global Mobile Location Center
- MPC Mobile Position Center
- VPC Voice IP Positioning Center
- the positioning center which retrieves, forwards, stores and controls emergency position data within the VoIP location network.
- XPC network is used herein when appropriate to refer to any non-landline network where a positioning center 402 responds to ALI 401 a, 401 b queries for location i.e. cellular, VoIP etc.
- PSAP refers herein to either a public safety access point (PSAP), or to an Emergency Call Center (ECC), a VoIP term.
- PSAP public safety access point
- ECC Emergency Call Center
- PSAP location data delivery
- CPE customer premise equipment
- ALI-XPC interface types Multiple implementations of ALI-XPC interface types are possible.
- Conventional ALI networks are overly complex because ALI networks nationwide must support multiple and varied ALI-XPC interfaces with different configurations.
- Each carrier selects a single XPC to provide location data for its callers-not all XPCs have connectivity with all the ESME/ALI servers associated with the corresponding PSAPs that may be requesting location.
- Conventional XPCs for a non-landline service provider are required to handle many aspects in the emergency services call flow—from routing an emergency E9-1-1 call to the relevant PSAP; to providing ALI information to the PSAP. This creates a highly complex architecture. There is a need for an architecture and methodology that both simplifies the complexity of the national PSAP and/or ALI network, and which also increases system efficiencies by reducing required system elements.
- ALI/ESME Steering Gateway a new E9-1-1 element called an “ALI/ESME Steering Gateway” is introduced.
- the concept of ALI/ESME Steering Gateway 100 is illustrated in FIG. 1 .
- the “ALI/ESME Steering Gateway” 100 appears as an XPC to the ALI/ESME requesting location data delivery; and as an ESME/ALI to the XPC that possesses the location information for the caller.
- ALI/ESME Steering Gateway addresses the complexity of supporting various ALI-XPC interfaces with different configurations and interface protocols; and the fact that not every carrier's XPC has connectivity with all the ESME/ALI servers associated with the corresponding PSAPs.
- ALI/ESME Steering Gateway provides nationwide connectivity between XPCs and regional and standalone ALI (SALI) databases through a single contact point.
- ALI/ESME Steering Gateway takes over the burden from the XPC of delivering ALI information to the PSAP via whatever technology or interface protocol the PSAP's ALI requires.
- ALI/ESME Steering Gateway provides the following added functionality to the non-landline network:
- an ALI/ESME Steering Gateway comprises a plurality of protocol agents for communicating with respective ALI systems each having a different communication protocols for communicating with an XPC.
- An inbound ALI interface to ALI/ESME Steering Gateway connects each of the plurality of protocol agents to the respective ALI systems.
- An outbound ALI interface to ALI/ESME Steering Gateway connects each of the plurality of protocol agents to respective XPCs (positioning centers).
- a method of translating and properly formatting automatic location identification (ALI) requests of one type interface protocol to an XPC of another type interface protocol comprises receiving an ALI request of an inbound ALI interface using a first type interface protocol.
- the ALI request is converted into a second type interface protocol different from the first type.
- the converted ALI request is transmitted over an outbound ALI interface using the second type interface protocol, wherein an ALI request of one type IP protocol is able to access an MPC using a different type IP protocol.

- the ALI/ESME Steering Gateway 100 selects the appropriate XPC for each ALI query it receives, and passes the query; providing protocol translation between the two ALI-XPC interface sets (inbound and outbound) as required.
- the ALI/ESME Steering Gateway 100 also consolidates (or “de-duplicates”) any/all duplicated requests from a same PSAP/ALI for the same emergency call. In this way, only one request is then sent to the destined XPC within the relevant XPC network.

Abstract
An ALI/ESME steering gateway bridges the nationwide ALI/ESME network notes (or PSAPs) with the GMLC/MPCs of various different XPC networks. The steering gateway provides a unified interface between the PSAP/ALI network and positioning centers (GMLC/MPC/VPCs). Using the steering gateway, an E911 service provider accesses positioning centers (GMLC/MPC/VPC) of any XPC network. This access by the ALI to the positioning center is accomplished with any type of interface, irregardless of the protocol type. The connectivity of each virtual communication path between ALIs and PSAPs is managed. The ALI/ESME steering gateway also provides translation of the protocols between the two ALI-MPC interface sets (inbound and outbound). The ALI/ESME steering gateway also consolidates (or “de-duplicates”) any/all duplicated requests from a same ALI or PSAP for the same emergency call so that only one request is then sent to the destined positioning center within the relevant network.

- This invention relates generally to wireless telecommunication. More particularly, it relates to the delivery of location information to PSAP/ALI systems in a non-landline environment i.e. cellular, VoIP etc in an emergency services call flow.
- 2. Background of Related Art
- 9-1-1 is a phone number widely recognized in North America as an emergency phone number that is used to contact emergency dispatch personnel. Enhanced 9-1-1 (E9-1-1) is defined by the transmission of callback number and location information when 9-1-1 is used. E9-1-1 may be implemented for landline, cellular or VoIP networks. A Public Service Answering Point (PSAP) is a dispatch office that receives 9-1-1 calls from the public. A PSAP may be a local, fire or police department, an ambulance service or a regional office covering all services.
- Regardless of the network type, a 9-1-1 service becomes E-9-1-1 when automatic number identification and automatic location information related to the call is provided to the 9-1-1 operator at the PSAP. A primary challenge results from the fact that calls may arrive at the PSAP without callback number or location information displayed at the emergency operators terminal.
- A PSAP is connected to one Automatic Location Identifier (ALI). An ALI is a database that accepts a PSAP query with telephone number, relates the telephone number to an address and provides that address (location information) back to the PSAP in a manner that works for the customer premise equipment (CPE) display. An ALI is typically owned by a LEC or a PSAP, and may be regional (i.e. connected to many PSAPs) or standalone (i.e. connected to only one PSAP). There is no one single standard interface protocol for PSAP-ALI connection/communication.
- Most PSAPs are publicly funded and maintain only one outside ALI connection for both landline and non-landline networks. Some ALIs are able to support only one outside connection to a positioning center. This is problematic for non-landline networks, which have users who are inherently mobile and may be in a particular PSAP-ALI jurisdiction, but their provider does not maintain a connection to the PSAP/ALI.
-
FIG. 7 shows a conventional landline public safety access point (PSAP) to automatic location identifier (ALI) connection. - In particular, upon receiving a 9-1-1 call, the PSAP queries their ALI for location data. As shown in
FIG. 7 in landline telephony, an ALI 401 accepts a PSAP 400 query for location and returns location based on pre-provisioned data for the telephone number. -
FIG. 8 shows a context diagram for a conventional non-landline XPC network. - In particular, as shown in
FIG. 8 in non-landline telephony, PSAPs 400 a, 400 b query thesame ALI PSAP - Non-landline telephony standards (e.g. cellular, VoIP etc) have mandated that
ALIs positioning center 402 provides the caller's location and the callback number to the ALI, which passes it to the requesting PSAP. As can be seen inFIG. 8 , an ALI may maintain connectivity to more than one positioning center via anmultiple interface types - As used herein, the generic term “XPC” refers interchangeably to any standards-based positioning center.
- A
positioning center 402 may be any one of the following types used in non-landline networks: - GMLC (Gateway Mobile Location Center): The positioning center that retrieves, forwards, stores and controls emergency position data within the GSM location network.
- MPC (Mobile Position Center): The positioning center that retrieves, forwards, stores and controls emergency position data within the ANSI location network.
- VPC (VoIP Positioning Center): The positioning center which retrieves, forwards, stores and controls emergency position data within the VoIP location network.
- The term “XPC network” is used herein when appropriate to refer to any non-landline network where a
positioning center 402 responds to ALI 401 a, 401 b queries for location i.e. cellular, VoIP etc. - The term “PSAP” refers herein to either a public safety access point (PSAP), or to an Emergency Call Center (ECC), a VoIP term.
- There is no uniformity among the thousands of different PSAPs with regard to how they request location data delivery (e.g. there are many different protocol interfaces), or as to how that data displayed on the PSAP customer premise equipment (CPE) varies, because the technology for connecting calls varies between the many manufacturers of, and carriers using, ALI devices. Moreover, some PSAPs are not enhanced, and thus do not receive the callback or location information at all from any phone, be it landline, cellular or VoIP.
- Multiple implementations of ALI-XPC interface types are possible. Conventional ALI networks are overly complex because ALI networks nationwide must support multiple and varied ALI-XPC interfaces with different configurations.
- Each carrier selects a single XPC to provide location data for its callers-not all XPCs have connectivity with all the ESME/ALI servers associated with the corresponding PSAPs that may be requesting location. Conventional XPCs for a non-landline service provider are required to handle many aspects in the emergency services call flow—from routing an emergency E9-1-1 call to the relevant PSAP; to providing ALI information to the PSAP. This creates a highly complex architecture. There is a need for an architecture and methodology that both simplifies the complexity of the national PSAP and/or ALI network, and which also increases system efficiencies by reducing required system elements.
- In accordance with the principles of the invention, a new E9-1-1 element called an “ALI/ESME Steering Gateway” is introduced. The concept of ALI/ESME Steering Gateway 100 is illustrated in
FIG. 1 . The “ALI/ESME Steering Gateway” 100 appears as an XPC to the ALI/ESME requesting location data delivery; and as an ESME/ALI to the XPC that possesses the location information for the caller. - ALI/ESME Steering Gateway addresses the complexity of supporting various ALI-XPC interfaces with different configurations and interface protocols; and the fact that not every carrier's XPC has connectivity with all the ESME/ALI servers associated with the corresponding PSAPs. ALI/ESME Steering Gateway provides nationwide connectivity between XPCs and regional and standalone ALI (SALI) databases through a single contact point. ALI/ESME Steering Gateway takes over the burden from the XPC of delivering ALI information to the PSAP via whatever technology or interface protocol the PSAP's ALI requires.
- ALI/ESME Steering Gateway provides the following added functionality to the non-landline network:
- Manages the connectivity for each individual ALI-XPC interface, freeing the each from having to maintain multiple connections;
- Provides protocol translation between ALI-XPC interface sets (inbound and outbound), freeing each from having to support multiple interface protocols;
- Consolidates (de-duplicates) duplicated requests from the same PSAP for the same emergency call: sending only one request if required to the XPC
- In accordance with the principles of the present invention, an ALI/ESME Steering Gateway comprises a plurality of protocol agents for communicating with respective ALI systems each having a different communication protocols for communicating with an XPC. An inbound ALI interface to ALI/ESME Steering Gateway connects each of the plurality of protocol agents to the respective ALI systems. An outbound ALI interface to ALI/ESME Steering Gateway connects each of the plurality of protocol agents to respective XPCs (positioning centers).
- A method of translating and properly formatting automatic location identification (ALI) requests of one type interface protocol to an XPC of another type interface protocol in accordance with another aspect of the invention comprises receiving an ALI request of an inbound ALI interface using a first type interface protocol. The ALI request is converted into a second type interface protocol different from the first type. The converted ALI request is transmitted over an outbound ALI interface using the second type interface protocol, wherein an ALI request of one type IP protocol is able to access an MPC using a different type IP protocol.

-
FIG. 1 shows an exemplary ALI network including an ALI/ESME Steering Gateway 100, in accordance with the principles of the present invention. - In particular, as shown in
FIG. 1 the ALI/ESME Steering Gateway 100 provides a unified interface between each PSAP/ALI in the national PSAP/ALI network, and positioning centers (XPCs) 1-5 in every non-landline network e.g. cellular, VoIP etc. - The inventive ALI/
ESME Steering Gateway 100 manages the connectivity between individual PSAP/ALIs 510-515 and XPCs 1-5 (e.g. TCP/IP, frame relay etc). In accordance with the present invention, access by the ALI to the XPC is accomplished with any type of interface, irregardless of the protocol type. - When the PSAP/ALI 510-515 requests location, the ALI/
ESME Steering Gateway 100 handles protocol conversions as required between existing and future ALI protocols (vepv 2, e2, e2+, PAM, legacy NENA, etc.) to the appropriate protocol used to communicate with the XPC that can provide location data. - The ALI/
ESME Steering Gateway 100 selects the appropriate XPC for each ALI query it receives, and passes the query; providing protocol translation between the two ALI-XPC interface sets (inbound and outbound) as required. - Preferably, the ALI/
ESME Steering Gateway 100 also consolidates (or “de-duplicates”) any/all duplicated requests from a same PSAP/ALI for the same emergency call. In this way, only one request is then sent to the destined XPC within the relevant XPC network. - The ALI/
ESME steering gateway 100 may also implement an ALI update request throttling as described in U.S. Provisional Patent Application No. 60/700,345, the entirety of which is expressly incorporated herein by reference. - On the ‘inbound’ ALI-MPC interfaces of the ALI/
ESME Steering Gateway 100, shown generally on the left-hand side ofFIG. 1 , various exemplary interface protocols are shown, e.g. PAM, legacy NENA, NENA ESP, European OMA MLP and the pre-standard VoIP E2. Similarly, ‘outbound’ ALI-MPC interfaces of the ALI/ESME Steering Gateway 100, may include the same (or different) type interfaces, as shown generally on the right-hand side ofFIG. 1 . - Upon receipt of a location request from any of the various PSAP/ALIs 510-515, the ALI/
ESME Steering Gateway 100 determines the correct XPC 1-5 servicing the call by accessing a suitable location to carrier lookup table 561. Most importantly, in that lookup, the outbound interface protocol type for accessing the relevant XPC 1-5 of the determined carrier's network is determined (e.g., E2, PAM, legacy NENA, NENA ESP or OMA MLP etc). - Because of the flexibility imported by the implementation of an ALI/
ESME Steering Gateway 100 in accordance with the principles of the present invention, important network improvements can be accomplished. - For instance, the ALI/
ESME Steering Gateway 100 preferably includes the capability to convert a single location request from a PSAP/ALI 510-515 to multiple ALI queries. Thus, the ALI/ESME steering gateway 100 may initiate multiple ALI location request queries to relevant XPCs 1-5 on the ‘outbound’ ALI interface shown generally on the right side ofFIG. 1 . - Another important network improvement is that the ALI/
ESME steering gateway 100 can provide, as desired, the ability to de-duplicate duplicate location requests for a same emergency call. In this respect, it is possible that multiple location request queries may be received for the position of a same mobile device. In such a case, multiple duplicated ALI queries may be received by the ALI/ESME Steering Gateway 100. Thus, ALI/ESME Steering Gateway 100 may operate in a networked redundant mode that is capable of consolidating multiple identical ALI location requests from the same inbound ALI interface grouping (i.e. to/from the same PSAP). In such case, the ALI/ESME -
Steering Gateway 100 should exchange information in realtime so that the requesting device (e.g., an ALI) and the receiving device (e.g. an XPC) can coordinate and consolidate any duplicated ALI location requests received independently. - As mentioned previously, a PSAP must be capable of querying a variety of XPC networks that are determined to be responsible for a given emergency caller. The ALI/
ESME Steering Gateway 100, using the location to carrier lookup table 561, determines which XPC 1-5 network a received ALI location request should be steered to, removing the burden of this from the PSAP/ALI system 510-515. Thus, the ALI/ESME steering gateway determines whether a consolidated ALI location request query should be steered, and to which XPC 1-5 the query should be steered to. - In one embodiment, this can be accomplished by checking the query key, i.e., the Emergency Service Routing Key (ESRK) or the Emergency Service Routing Digits (ESRD). This query key is compared to a database in the location to carrier lookup table 561 that contains information about which particular carrier owns that particular ESRK and/or ESRD. The carrier is matched to a particular XPC 1-5 for location servicing.
- Once the ALI/
ESME steering gateway 100 determines where a consolidated ALI location request query should be steered, based on the configuration of the outbound ALI interface, the ALI/ESME Steering Gateway 100 formats the received ALI location request query in the appropriate interface protocol type for the outbound ALI interface. Optionally, the ALI/ESME steering gateway 100 can generate multiple redundant ALI location request queries over the outbound ALI interface. -
FIG. 2 shows an exemplary ALI/ESME steering gateway, in accordance with the principles of the present invention. - In particular, as shown in
FIG. 2 , the exemplary ALI/ESME steering gateway 100 comprises an ‘inbound’ALI interface protocol 601, and an ‘outbound’ALI interface protocol 602. The ‘inbound’ and ‘outbound’ interfaces protocols may utilize one of a variety of connection protocols (e.g. TCP/IP, frame relay), and may access the public world wide web (the Internet) and/or a local Intranet. - The ALI/
ESME Steering Gateway 100 includes asuitable software agent 607 capable of establishing and maintaining a virtual connection between a given ALI/ESME of the respective protocol type (e.g., E2) with a XPC of the same respective protocol type. Protocol conversion is accomplished in a suitable processor associated with an ALIrouter steering control 621 having a data bus in communication with eachsoftware agent 607 a to 607 f. The ALI/ESME Steering Gateway 100 further includes anemergency call de-duplicator 622, providing the ability to de-duplicate duplicate location requests for a same emergency call. - During the transaction of steering a given ALI location request query, the ALI/
ESME Steering Gateway 100 maintains the connection management for theinbound ALI interface 601 and theoutbound ALI interface 602 separately. At the same time, however, the ALI/ESME Steering Gateway 100 coordinates the inbound and outbound ALI interfaces 601, 602, so that when the response(s) to the location request query (or queries) of theoutbound ALI interface 602 is received, the ALI/ESME Steering Gateway 100 can translate and format a proper response(s) on theinbound ALI interface 601. -
FIGS. 3A through 3B are a table showing possible ALI-MPC interface steering types, in accordance with an exemplary embodiment of the present invention. These interfaces currently exist in the PSAP/ALI network, and are used as examples for steering scenarios. - For example, as shown in
FIGS. 3A through 3B , possible steering scenarios include steering ALI location requests from an ALI/ESME utilizing PAM protocols (e.g., PAM v6.1) (row 301) to any type XPC, e.g., XPC using the same PAM interface (column 311), or to an XPC using an SR/ALI E2 type protocol , e.g.,NENA 05 redundant note primary/secondary operation as depicted incolumn 312. Similarly, ALIs using other protocols as depicted in rows 302-306 ofFIG. 6 can communicate with XPCs using any protocol as depicted in columns 311-316—or any future protocols, using an ALI/ESME Steering Gateway 100 in accordance with the principles of the present invention. -
FIG. 4 depicts ALI-XPC interface steering from a network context, in accordance with the principles of the present invention. - In particular, as shown in
FIG. 4 , aPSAP 901 makes an ALI location request of a relevant ALI/ESME ESME Steering Gateway 100, and is routed through relevantALI router agents XPC ALI router agents -
FIGS. 5A through 5B and 6 show message flow for ALI steering between representative protocol types, in accordance with the principles of the present invention. These Figures are intended to illustrate to those of ordinary skill in the art exemplary message flows of the E2 ALISA to SR/ALI-E2 Steering and the PAM to SR/ALI-E2 Steering, as examples of ALI Steering implementation. Of course, as depicted in the table ofFIG. 6 , many other combinations and conversions of protocols may be implemented with ALI steering in accordance with the principles of the present invention. -
FIGS. 5A through 5B are exemplary call flow diagrams showing a successful E2 ALISA (Fully Connected Redundant Node, Both Mode) to SR/ALI-E2+ Steering, in accordance with the principles of the present invention. - In particular, as shown in step (a) of
FIGS. 5A-5B , as ALI/ESME-1 561 and ALI/ESME-2 562 are in Both Mode (both ESMEs query each of theMPCs ESME ALI router agent 1 564 running in the ALI/ESME Steering Gateway 100. - In step (b), ALI/ESME-1 561 sends an identical ESPOSREQ to
ALI router agent 2 563 running in the ALI/ESME Steering Gateway 100 for position. Note that this ESPOSREQ has the same transaction ID as the one in the ESPOSREQ received in Step (a). - In step (c), ALI/ESME-2 562 also sends an identical ESPOSREQ to
ALI router agent 2 563. Note that the Transaction ID in this ESPOSREQ will be different from the one in steps (a) and (b). - In step (d), ALI/ESME-2 562 sends an identical ESPOSREQ to
ALI router agent 1 564. Note that this ESPOSREQ has the same Transaction ID as the one in the ESPOSREQ received in step (c). - In step (e), the ALI/
ESME Steering Gateway 100 may start a timer when it first receives an ESPOSREQ message from one of ALISA connections. Any identical E2 ALISAESPOSREQ requests received before the timer expiration shall be considered as duplicated requests; any identical E2 ALISAESPOSREQ requests received after the timer expires shall be considered as a new ALISA transaction. On receiving the identical ESPOSREQs, theALI router agent 1 564 and theALI router agent 2 563 shall exchange information, process only the first received ESPOSREQ (or decide which one to process by other manner). In this message flow, theALI router agent 1 564 handles the request. - Upon receipt of the ESPOSREQ messages, the ALI router agent determines the Query Key (ESRK or ESRD included in the first received query), and is configured to be steered to an outbound SR/ALI E2+ grouping.
ALI router agent 1 564 andALI router agent 2 563 are coordinated so that the ALI/ESME Steering Gateway 100 starts an ALI Steering Timeout timer whenever it is ready to generate queries to the outbound SR/ALI E2+ interface. The ESPOSREQ that is being processed is forwarded to theXPC 566 with a new Transaction ID via the primary outbound connection, and an ESPRT timer is started. - In step (f), the XPC-1 566 returns position information in an esposreq message. The ALI/
ESME Steering Gateway 100 stops the ALI Steering Timeout timer when it receives the results of the outbound steered ALI transaction. - In step (g),
ALI router agent 1 564 returns an esposreq with the requested position information to the ALI/ESME-1 561. TheALI router agents 563, 564 manage the state for each TCP/IP session to ALISA. In the case that the selected session (ESPOSREQ) for response is out of service, theALI router agents 563, 564 can use a different route from which theALI router agent 563, 564 has received the same query. - In step (h),
ALI router agent 2 563 returns an esposreq with Position Result=04 (requestedPositionNotAvailable) or other error code, without position info to the ALI/ESME-1 561. - In step (i),
ALI router agent 2 563 returns an esposreq with Position Result=04 (requestedPositionNotAvailable) or other error code, without position info to the ALI/ESME-2 562. - In step (j),
ALI router agent 1 564 returns an esposreq with Position Result=04 (requestedPostionNotAvailable) or other error code, without position info to the ALI/ESME-2 562. -
FIG. 6 is an exemplary call flow diagram showing a successful PAM to SR/ALI-E2 Steering, in accordance with the principles of the present invention. - In particular, as shown in step (a) of
FIG. 6 , an ALI/ESME-1 661 queries a relevantALI router agent 1 664 for position by sending a PAM “00”, “01” or “02” request with ANI (ESRK). - In step (b), an ALI/ESME-2 662, which is a mated PAM pair with the ALI/ESME-1 661, sends an identical PAM “00”, “01” or “02” request to the connected
ALI Router agent 2 663. - In step (c), on receiving the first PAM “00”, “01” or “02” query from a mated PAM pair, the ALI/ESME Steering Gateway 100 (geographically redundant
ALI router agent 1 andALI router agent 2 belong to the same ALI/ESME Steering Gateway 100) start a timer. When this timer expires, any newly received PAM query is considered as a new transaction. Within a “Purge Interval” period, an identical PAM “00”, “01” or “02” is expected as the first query. The ALI/ESME Steering Gateway 100 coordinates theALI router agent 1 664 andALI router agent 2 663. TheALI router agent 2 663 responds to the second PAM “00”, “01” or “02” query, which is identical to the first received PAM query, with a PAM “04” message with response code=02 (short response). Note: Two PAM queries are considered to be identical if the following information elements of the two queries are exactly the same: MESSAGE TYPE, PSAPID, ANI, POSITION and TRUNK. - In step (d), based on the first received PAM query, the ALI/
ESME Steering Gateway 100 determines if the query needs to be steered, and to which outbound ALI interface it is to be steered based on the included ESRK. In the given exemplary scenario ofFIG. 6 , the query is steered to an outbound SR/ALI-E2 type interface. - The
ALI router agent 1 664 andALI router agent 2 663 are coordinated, so that the ALI/ESME Steering Gateway starts an ALI Steering Timeout timer whenever the ALI/ESME Steering Gateway 100 is ready to generate queries to an outbound SR/ALI-E2 interface. One ESPOSREQ message is generated, by translating the information received in the PAM query to the corresponding ESPOSREQ information elements. TheALI router agent 1 664 sends an ESPOSREQ and starts an ESPRT timer for the query. - In step (e), a XPC-1 666 sends position information in an esposreq message back to the
ALI router agent 1 664. The corresponding ESPRT is stopped.ALI router agent 1 stops the ALI Steering Timeout timer when it receives the result of the outbound steered ALI transaction. - In step (f), upon receiving position information in an esposreq message, the
ALI router agent 1 664 translates the received information to the information elements in the PAM “04” message format, and sends it back to the ALI/ESME-1 661. - While the invention has been described with reference to the exemplary embodiments thereof, those skilled in the art will be able to make various modifications to the described embodiments of the invention without departing from the true spirit and scope of the invention.
