Abstract

Systems and methods are provided for reliable, wireless group messaging or alerting in a system having a database, switch, wireless network, and a plurality of intelligent mobile receivers. A message is broadcast to and received by a selected group of the mobile receivers. The network replies to the sender with detailed information about the individual members in the group. Each of the mobile receivers in the group can acknowledge the group message back to the system such as when the message is received, when the message is read, and a response when sent. The system employs centralized management to provide the sender with response information of the mobile receivers.

Claims

1. A method of alerting a group of recipients over a wireless network, each recipient comprising a mobile device capable of transmitting and receiving data, the method comprising the steps of:

storing for at least some of the recipients corresponding recipient identifiers;

storing one or more group identifiers corresponding to one or more groups of recipients that are shared with selected ones of the recipients;

receiving a communication from a network client requesting transmission of a message to recipients sharing a selected one of the group identifiers;

transmitting a communication to the network client, the communication comprising group information relating to the selected one of the group identifiers, the group information comprising at least one of;

(a) a count of those of the recipients having the selected one of the group identifiers and (b) the recipient identifiers of those of the recipients having the selected one of the group identifiers;

transmitting the message to those of the recipients having the selected one of the group identifiers via a wireless network;

receiving acknowledgment responses from at least one of those of the recipients having the selected one of the group identifiers via the wireless network in response to each respective recipient'"'"'s receipt of the message, the acknowledgement responses each comprising recipient identifying information and an indication of successful receipt of the message;

providing the acknowledgment responses to the network client; and

storing, for those recipients having the selected one of the group identifiers, the respective recipient identifying information for each respective recipient and a corresponding message alert status indicator indicating at least one of (a) receipt of the message by the respective recipient or (b) that the message has been sent, but not received by the respective recipient;

wherein message alert status for those recipients having the selected one of the group identifiers is determined, including at least identifying which of those recipients having the selected one of the group identifiers received the message and which of those recipients having the selected one of the group identifiers have not yet received the message, using the stored message alert status indicator of each respective recipient having the selected one of the group identifiers.

2. A method as claimed in claim 1, further comprising the step of displaying content of the message.

3. A method as claimed in claim 1, further comprising the step of displaying a group name corresponding to the selected group identifier.

4. A method as claimed in claim 1, further comprising the step of displaying multiple choice options for responding to the message on a display operated by the recipient.

5. A method as claimed in claim 1, wherein the acknowledgement responses comprise an indication that at least one recipient has read the message.

6. A method as claimed in claim 1, wherein the message indicates that the recipients are to perform at least one of a plurality of operations comprising sending acknowledgement that the message was received, sending acknowledgement that the message was read, and selecting from among a number of multiple choice response options.

7. A method as claimed in claim 1, wherein the message employs a group address.

8. A method as claimed in claim 1, wherein the message instructs the recipients to assign a symbolic group name to the group.

9. A method as claimed in claim 1, wherein the message comprises a response request message.

10. A method as claimed in claim 1, further comprising the step of receiving responses from recipients having the selected one of the group identifiers.

11. A method as claimed in claim 10, further comprising the step of notifying the network client as recipients perform at least one operation consisting of receiving the message.

12. A method as claimed in claim 10, further comprising the step of notifying the network client as recipients perform at least one operation consisting of alerting users of the received message.

13. A method as claimed in claim 10, further comprising the step of notifying the network client as recipients perform at least one operation consisting of displaying the message.

14. A method as claimed in claim 10, further comprising the step of the recipients providing status information in the responses to convey status of multiple recipients in the group having the selected one of the group identifiers to the network client.

15. A method as claimed in claim 14, wherein the status information comprises a timestamp for when the response was received from the recipient.

16. A method as claimed in claim 14, wherein the status information comprises a confirmation that the message was displayed via the recipient.

17. A method as claimed in claim 14, wherein the status information comprises a confirmation that the response was one of multiple choices for responses provided to the recipient.

18. A method as claimed in claim 1, further comprising:

storing at least one of a symbolic name and a corresponding encryption key for each of a number of group identifiers; and

replicating via wireless transactions the at least one of symbolic name and a corresponding encryption key in a memory device of the recipient for each of the group identifiers to which a recipient belongs.

19. A method as claimed in claim 18, wherein the step of transmitting the message to those of the recipients having the selected one of the group identifiers via a wireless network comprises:

generating and transmitting a one-way, ReFLEX protocol-formatted, one-to-many broadcast group alert message comprising an information service (IS) message, and further comprising the steps of;

the recipients assigning the symbolic name of the selected group address to an IS address shared by the recipients; and

displaying the symbolic name on respective displays of the recipients.

20. A method as claimed in claim 18, wherein the symbolic name is a small mnemonic value, and further comprising the steps of:

receiving responses to the message from the recipients sharing the selected group address, the responses being compressed by the recipients using the small mnemonic value for the selected group address in the responses.
