Abstract

A method of sending alerts from servers to client devices is provided. The alert can be generated with a server application and may include customer information. The alert may then be sent to a message router. The message router retrieves a station ID of the client device based on the customer information. A communication type of the client device can be determined based on the station ID and one or more of a plurality of protocol gateways can be selected based on the communication type. The alert can be forwarded to the selected one or more of the plurality of protocol gateways where is may be formatted for the selected client device. The formatted alert may then be forwarded via the network to the selected client device.

40. The method of sending a message to a client device according to claim 37, wherein:

said step of determining a communication type further comprises searching a local cache of said message router for said identification information associated with a customer ID.

41. The method of sending a message to a client device according to claim 37, wherein:

said step of determining a communication type further comprises searching a local cache of said message router and a device table for said client device associated with said identification information when both said identification information and a port number are provided.

42. The method of sending a message to a client device according to claim 37, further comprising:

returning an inactive customer message to a server if no identification information is retrieved.

43. The method of sending a message to a client device according to claim 37, wherein:

said message is segmented with said selected at least one protocol gateway into message segments before sending said message over a network.

44. The method of sending a message to a client device according to claim 43, wherein:

said segmented message is assembled at said client device.

45. The method of sending a message to a client device according to claim 37, wherein:

said message includes at least one of an alert message, a compression flag, an encryption flag, and an acknowledgement flag.

46. The method of sending a message to a client device according to claim 37, further comprising:

returning an acknowledgement to said selected at least one protocol gateway after receiving said formatted message at said client device.

47. The method of sending a message to a client device according to claim 46, further comprising:

forwarding said acknowledgement from said selected at least one protocol gateway to a server.

48. The method of sending a message to a client device according to claim 37, wherein:

said client information is a client information object.

49. The method of sending a message to a client device according to claim 37, wherein:

said client information includes a customer ID and a device ID.

50. The method of sending a message to a client device according to claim 49, wherein:

said message includes an active device only flag; and

said device ID can be set to all devices.

51. The method of sending a message to a client device according to claim 50, further comprising:

searching a local cache of said message router for said identification information if said active device only flag is set and said device ID is specified.

52. The method of sending a message to a client device according to claim 37, further comprising:

searching a user table for said identification information if said identification information is not located in said local cache.

53. The method of sending a message to a client device according to claim 50, further comprising:

searching only a user table for active client devices associated with said customer ID if said active device only flag is set and said device ID is set to all devices.

54. The method of sending a message to a client device according to claim 50, further comprising:

searching a local cache of said message router for said identification information if said active device only flag is not set and said device ID is specified.

55. The method of sending a message to a client device according to claim 37, further comprising:

searching a device table for said identification information if said identification information is not located in a local cache.

56. The method of sending a message to a client device according to claim 50, further comprising:

searching a device table for a client device associated with said customer ID if said active only flag is not set and said device ID is set to all devices.

57. The method of sending a message to a client device according to claim 37, further comprising:

providing each identification information retrieved in said step of retrieving identification information to a server.

58. The method of sending a message to a client device according to claim 37, further comprising:

providing each identification information retrieved by said message router to a server, before forwarding said message to said at least one protocol gateway.

59. A method of sending an message to a client device, comprising:

retrieving, at a message router, identification information from at least one of customer information and device information;

determining, at said message router, a communication type associated with said at least one of customer information and device information; and

forwarding said message to at least one protocol gateway associated with said determined communication type;

wherein said message is transmitted with said at least one protocol gateway over a network to said client device.

60. The method of sending an message to a client device according to claim 59, further comprising:

receiving said message with a transport layer of an application associated with said at least one protocol gateway; and

sending said message from said transport layer to a client application.

61. The method of sending an message to a client device according to claim 59, wherein:

said message is segmented into message segments with said at least one protocol gateway.

62. The method of sending an message to a client device according to claim 60, wherein:

said client application assembles said message segments.

63. The method of sending an message to a client device according to claim 59, wherein:
