Abstract

A subscriber'"'"'s PMU (Personal Messaging Unit) (14) determines when the number of incoming messages is likely to be excessive by counting the incoming messages and comparing their number and rate of receipt to stored thresholds. The subscriber is alerted when an excess is detected, and he is given options such as: routing future messages to himself via alternate and less expensive communication links (34,38), or terminating messages sent to one of his PMU'"'"'s addresses that has been receiving messages at a high rate. Similar control can be effected at the PMU'"'"'s base station (12).

Claims

1. A method for a subscriber'"'"'s portable messaging unit to control the number, and associated cost, of messages transmitted to it by a wireless messaging service, comprising in the subscriber'"'"'s portable messaging unit the steps of:

a) storing a threshold number that indicates a number of messages to be received within a given period of time;

b) receiving incoming messages;

c) determining whether the number of incoming messages is likely to exceed the threshold number; and

d) if the threshold number is likely to be exceeded, instructing the messaging service to send messages to the subscriber via an alternate route.

2. A method as set forth in claim 1 wherein step c) includes determining the rate at which messages are received.

3. A method as set forth in claim 1 wherein the personal messaging unit has multiple addresses, wherein messages may be sent to each of the multiple addresses, and wherein when the number of incoming messages exceeds the threshold number, the personal messaging unit determines whether one of its addresses was receiving messages at an excessive rate.

4. A method as set forth in claim 3 wherein if one of the personal messaging unit'"'"'s addresses received messages at an excessive rate, the personal messaging unit alerts the subscriber to the identity of that one address.

5. A method of controlling the number, and associated cost, of messages transmitted by a wireless messaging service to a subscriber'"'"'s personal messaging unit, comprising:

a) storing a threshold number that indicates a number of messages to be received within a given period of time;

b) determining whether the number of messages sent to the personal messaging unit exceeds the threshold number;

c) if the threshold number is exceeded, giving the subscriber the option of changing the threshold number; and

d) if the subscriber does not exercise the option, instructing the messaging service to send messages to the subscriber via an alternate route.

6. A method as set forth in claim 5 wherein the personal messaging unit has multiple addresses, wherein messages may be sent to each of the multiple addresses, and including determining whether messages were sent to any one address of the personal messaging unit at an excessive rate.

7. A method for controlling the number, and associated cost, of messages transmitted by a wireless messaging service to a subscriber'"'"'s personal messaging unit that can receive messages sent to any one of multiple addresses, comprising:

a) storing a threshold number that indicates a number of messages to be received within a given period of time;

b) determining whether the number of messages sent to the personal messaging unit exceeds the threshold number; and

c) if the threshold number is not exceeded, and messages were sent to any one address of the personal messaging unit at an excessive rate, instructing the messaging service to send messages for that one address via an alternate route.

8. A method as set forth in claim 7 wherein if messages were sent to one of the personal messaging unit'"'"'s addresses at an excessive rate, the personal messaging unit alerts the subscriber to the identity of that one address.

9. A method as set forth in claim 7 wherein the threshold number is selected by the subscriber.

10. A method as set forth in claim 7 wherein a rate deemed to be excessive is determined by the subscriber.

11. A method for a subscriber'"'"'s personal messaging unit to control the number, and associated cost, of messages transmitted to it by a wireless messaging service, comprising in the subscriber'"'"'s portable messaging unit the steps of:

a) storing a threshold number that indicates a number of messages to be received within a given period of time;

b) receiving and counting incoming messages;

c) determining whether the number of incoming messages exceeds the threshold number; and

d) if the threshold number is exceeded, instructing the messaging service to send messages to the subscriber via an alternate route; and

e) if the threshold number is not exceeded, determining whether messages were sent to any one address of the personal messaging unit at an excessive rate.

12. A method for a wireless messaging service to control the number, and associated cost, of messages transmitted to a subscriber'"'"'s personal messaging unit that has multiple addresses, comprising in a base station of the wireless messaging service the steps of:

a) storing a threshold number that indicates a number of messages to be transmitted to the personal messaging unit within a given period of time;

b) counting messages transmitted to the personal messaging unit;

c) determining whether the number of messages transmitted to the personal messaging unit exceeds the threshold number;

d) if the threshold number is not exceeded, transmitting a message to the personal messaging unit; and

e) if the threshold number is exceeded, forwarding the message to the personal messaging unit via an alternate route.

13. A method as set forth in claim 12 including determining whether messages were sent to one of the personal messaging unit'"'"'s multiple addresses at an excessive rate.

14. A method as set forth in claim 13 wherein if an excessive rate is determined, a warning is transmitted to the subscriber.
