Method And Apparatus For Message Distribution In A Device Management System
A method and apparatus for managing CPE devices. In managing a CPE, an ACS must first establish a communication session with the CPE. In accordance with the present invention, the connection request formed by the ACS and containing proxy information is transmitted to a primary blast box. The primary blast box, which includes a blast box registry, forwards the connection request to a plurality of secondary blast boxes, each secondary blast box being associated with a respective CGN private network of the communications network. The secondary blast boxes in turn removes the proxy information and forwards the connection request to one or more CPEs in the private network encompassed by the corresponding CGN. Authentication information sent with the proxy information uniquely permits authentication of the connection request in the target CPE. When authentication occurs, the CPE initiates a communication session with the ACS so that the desired management function may be executed.
1 . A method of initiating communications with a CPE device associated with a communications network, the method comprising:
receiving in a primary blast box a connection request directed to the CPE, the connection request comprising proxy information, wherein the proxy information comprises an IP address associated with the CPE;
forwarding the connection request to at least one secondary blast box, wherein the at least one secondary blast box is associated with a private network of the communication network.
2 . The method of claim 1 , further comprising extracting the proxy information from the connection request and forwarding the connection request without the proxy information to the IP address associated with the CPE.
3 . The method of claim 2 , wherein the connection request without the proxy information is forwarded by the primary blast box.
4 . The method of claim 2 , wherein the connection request without the proxy information is forwarded by the at least one secondary blast box.
5 . The method of claim 1 , wherein the proxy information further comprises CR credentials previously generated and transmitted to the CPE.
6 . The method of claim 1 , wherein the proxy information further comprises a CR URL previously generated by the CPE.
7 . The method of claim 1 , further comprising generating the connection request in an ACS and transmitting the connection request to the primary blast box.
8 . The method of claim 7 , further comprising initiating a timer when the connection request is transmitted and generating a second request if a communication from the CPE has not been received prior to expiration of the timer.
9 . The method of claim 1 , further comprising forwarding the connection request to a tertiary blast box from the at least one secondary blast box.
10 . The method of claim 1 , wherein the at least one secondary blast box comprises a plurality of secondary blast boxes, wherein each secondary blast box of the plurality of secondary blast boxes is associated with a respective CGN.
11 . The method of claim 1 , further comprising receiving a connection-request status message from the at least one secondary blast box indicating whether authentication with the CPE was successful.
12 . The method of claim 11 , wherein the at least one secondary blast box comprises a plurality of blast boxes, and further comprising aggregating received connection-request status messages and transmitting a connection-request response message to the entity originating the connection request.
13 . A network element for facilitating communications with a CPE, comprising:
a processor;
a memory device in communication with the processor, the memory device comprising a secondary element registry;
a message handler controlled by the processor configured to receive connection request messages and to forward the connection request messages received in the network element to secondary network elements listed in the secondary element registry.
14 . The network element of claim 13 , wherein the network element is incorporated into an ACS that generates the connection request messages.
15 . The network element of claim 13 , wherein the message handler is further configured to determine an IP address associated with a connection request and to forward the connection request to the IP address.
16 . The network element of claim 13 , wherein the secondary element registry comprises a flag for each entry to indicate whether it is active or inactive, and wherein the message handler only forwards received connection requests to secondary network elements flagged as active.
17 . The network element of claim 13 , wherein the secondary element registry is dynamically updatable to reflect the addition or removal of private networks.
18 . The network element of claim 13 , wherein the received connection request messages comprise proxy information and wherein the message handler is further configured to remove the proxy information prior to forwarding.
19 . A system for managing CPE devices, comprising:
a primary blast box comprising a blast box registry; and
at least one secondary blast box comprising a CPE registry,
wherein the primary blast box is configured to receive a connection request from to forward the connection request to the at least one secondary blast box.
20 . The system of claim 19 , wherein the primary blast box comprises an ACS interface for receiving connection requests generated by the ACS.
