Abstract

Proximity-based mobile message delivery is described. In an embodiment, a first user stores a message intended for a second user on a first mobile terminal, while the first mobile terminal is located remote from a second mobile terminal of the second user. Subsequent to this, the first mobile terminal detects that it is now in proximity with the second mobile terminal, and this triggers the first mobile terminal to transmit the message to the second mobile terminal. In embodiments, authentication of the second mobile terminal can be performed before transmitting the message. In another embodiment, a mobile terminal comprises a short-range wireless transceiver that can detect that a further mobile terminal is in proximity, and trigger the transmission of a pre-stored message to the further mobile terminal.

Claims

1. A method of transmitting a message from a first mobile terminal to a second mobile terminal to simulate hand delivery of the message from a first user of the first mobile terminal to a second user of the second mobile terminal, the method comprising:

receiving a user-submitted message at the first mobile terminal, the message intended for personal delivery to the second user;

storing the message at the first mobile terminal;

pairing the first mobile terminal to the second mobile terminal, pairing including;

receiving a mutually agreed shared secret, the mutually agreed shared secret being entered at the first mobile terminal by the first user;

receiving a possible mutually agreed shared secret from the second mobile terminal;

when the possible mutually agreed shared secret is the mutually agreed shared secret, pairing the first mobile terminal to the second mobile terminal; and

when the possible mutually agreed shared secret is not the mutually agreed shared secret, rejecting pairing of the first mobile terminal to the second mobile terminal;

subsequent to storing the message, the first mobile terminal detecting that the second mobile terminal is in proximity to the first mobile terminal, indicating that the first user is in the presence of the second user; and

transmitting the message from the first mobile terminal to the second mobile terminal.

2. A method as recited in claim 1, wherein the first mobile terminal detecting that the second mobile terminal is in proximity to the first mobile terminal comprises:

the first mobile terminal sending information to the second mobile terminal identifying a physical location of the first mobile terminal; and

the first mobile terminal receiving information indicating whether the second mobile terminal is in proximity to the first mobile terminal.

3. A method as recited in claim 2, wherein the information indicating whether the second mobile terminal is in proximity to the first mobile terminal device is an indication of true or false.

4. A method as recited in claim 2, wherein the information indicating whether the second mobile terminal is in proximity to the first mobile terminal is an indication of a distance separating the first mobile terminal device and the second mobile terminal.

5. A method as recited in claim 1, further comprising:

determining a message type associated with the message;

when the message type is a first type, transmitting the message including, prior to transmitting the message from the first mobile terminal to the second mobile terminal, the first mobile terminal requesting further authentication from the second mobile terminal; and

when the message type is a second type, transmitting the message including transmitting without requesting further authentication from the second mobile terminal.

6. A method as recited in claim 1, wherein pairing includes:

receiving the mutually agreed shared secret via a wireless communication.

7. A method as recited in claim 1, wherein pairing includes detecting that the first mobile terminal and the second mobile terminal are touching.

8. A computer storage medium, the computer storage medium being hardware, storing computer-readable instructions which when executed perform actions to cause one or more processors to transmit a message from a first mobile terminal to a second mobile terminal to simulate hand delivery of the message from a first user of the first mobile terminal to a second user of the second mobile terminal, the actions comprising:

receiving a user-submitted message at the first mobile terminal, the message intended for personal delivery to the second user;

storing the message at the first mobile terminal;

pairing the first mobile terminal to the second mobile terminal, pairing including;

receiving a mutually agreed shared secret, the mutually agreed shared secret being entered at the first mobile terminal by the first user;

receiving a possible mutually agreed shared secret from the second mobile terminal;

when the possible mutually agreed shared secret is the mutually agreed shared secret, pairing the first mobile terminal to the second mobile terminal; and

when the possible mutually agreed shared secret is not the mutually agreed shared secret, rejecting pairing of the first mobile terminal to the second mobile terminal;

subsequent to storing the message, the first mobile terminal detecting that the second mobile terminal is in proximity to the first mobile terminal, indicating that the first user is in the presence of the second user; and

transmitting the message from the first mobile terminal to the second mobile terminal.

9. A computer storage medium as recited in claim 8, wherein the first mobile terminal detecting that the second mobile terminal is in proximity to the first mobile terminal comprises:

the first mobile terminal sending information to the second mobile terminal identifying a physical location of the first mobile terminal; and

the first mobile terminal receiving information indicating whether the second mobile terminal is in proximity to the first mobile terminal.

10. A computer storage medium as recited in claim 9, wherein the information indicating whether the second mobile terminal is in proximity to the first mobile terminal device is an indication of true or false.

11. A computer storage medium as recited in claim 9, wherein the information indicating whether the second mobile terminal is in proximity to the first mobile terminal is an indication of a distance separating the first mobile terminal device and the second mobile terminal.

12. A computer storage medium as recited in claim 8, the actions further comprising:

determining a message type associated with the message;

when the message type is a first type, transmitting the message including, prior to transmitting the message from the first mobile terminal to the second mobile terminal, the first mobile terminal requesting further authentication from the second mobile terminal; and

when the message type is a second type, transmitting the message including transmitting without requesting further authentication from the second mobile terminal.

13. A computer storage medium as recited in claim 8, wherein pairing includes:

receiving the mutually agreed shared secret via a wireless communication.
