Abstract

An architecture framework to realize Push-to-X services using cloud-based storage services. Push-to-X messages are transmitted between mobile units by messaging servers. The Push-to-X message may include a short text message contained wholly within the Push-to-X message, or the Push-to-X message may include one or more attachments that comprise multimedia contents, files, or location information, which are stored on storage servers, wherein the Push-to-X message identifies a location for retrieving the attachments from the storage servers. The Push-to-X messages may be sent to a single mobile unit identified by a Mobile Directory Number (MDN) or a group of mobile units identified by a list of MDNs or a Uniform Resource Identifier (URI).

Claims

1. A system for providing communications services in a wireless communications network, the system comprising:

one or more messaging servers interfacing with the wireless communications networks to provide the communications services to a plurality of mobile units, wherein the plurality of mobile units communicate in a Push-to-Talk (PTT) system, wherein the communications services comprise Push-to-X communications, and wherein the Push-to-X communications comprise a multi-media messaging service (MMS);

wherein the one or more messaging servers transmits a first control message for a first Push-to-X communication to a first mobile unit of the plurality of mobile units over the communications network;

wherein attachments for the Push-to-X communications are stored on one or more storage servers, the one or more storage servers being connected to the wireless communications networks;

wherein a Quality-of-Service for transfer of the attachments for the Push-to-X communications is treated differently from other traffic in the wireless communications network; and

wherein the first control message identifies a location for retrieving a first attachment for the first Push-to-X communication stored on the one or more storage servers.

2. The system of claim 1, wherein a text message is contained wholly within a second control message for a second Push-to-X transmitted, by the one or more messaging services, to the first mobile unit.

3. The system of claim 1, wherein the attachments for the Push-to-X communications comprise multimedia contents, files, location information, or a combination thereof.

4. The system of claim 1, wherein the one or more storage servers and the plurality of mobile units communicate with each other using a first protocol, and wherein the one or more messaging servers and the plurality of mobile units communicate with each other using a second protocol different from the first protocol.

5. The system of claim 1, wherein the one or more messaging servers and the plurality of mobile units communicate with each other using a Session Initiation Protocol (SIP).

6. The system of claim 1, wherein the one or more messaging servers and the plurality of mobile units communicate with each other using a Hypertext Transport Protocol (HTTP).

7. The system of claim 1, wherein the one or more storage servers and the plurality of the mobile units communicate with each other using a Hypertext Transport Protocol (HTTP).

8. The system of claim 7, wherein the attachments for the Push-to-X communications are uploaded to or downloaded from the one or more storage servers using Uniform Resource Locators (URLs).

9. The system of claim 1, wherein the one or more messaging servers provide the communications services to a single mobile unit identified by a Mobile Directory Number (MDN), a group of mobile units identified by a list of MDNs, or a group of mobile units identified by a Uniform Resource Identifier (URI).

10. The system of claim 1, wherein a gateway transports control messages for the Push-to-X communications and the attachments for the Push-to-X communications between foreign systems.

11. The system of claim 1, wherein the first mobile unit downloads a subset of the attachments for the Push-to-X communications using a Uniform Resource Identifier (URI) provided by the one or more messaging servers.

12. The system of claim 11, wherein the Uniform Resource Identifier (URI) is allocated only when the first mobile unit requests a download of the subset of the attachments for the Push-to-X communications.

13. The system of claim 11, wherein the Uniform Resource Identifier (URI) expires after a specified duration.

14. The system of claim 1, wherein the communications service interfaces with the PTT service to access PTT call states, contact lists, and pre-arranged group lists for the plurality of mobile units.

15. The system of claim 1, wherein transmission of the attachments for the Push-to-X communications is avoided during a PTT call.

16. The system of claim 1, wherein transmission of the attachments for the Push-to-X communications is preempted when the first mobile unit receives or originates a PTT call.

17. The system of claim 14, wherein the Push-To-X communications are performed among participants of a PTT call.

18. A method of providing communications services in a wireless communications network, the method comprising:

interfacing, by one or more messaging servers, with the wireless communications networks to provide the communications services to a plurality of mobile units, wherein the communications services comprise Push-to-X communications, wherein the Push-to-X communications comprise a multi-media messaging service, and wherein the plurality of mobile units communicate in a Push-to-Talk system;

transmitting, by the one or more messaging servers, a first control message for a first Push-to-X communication to a first mobile unit of the plurality of mobile units over the communications network;

wherein attachments for the Push-to-X communications are stored on one or more storage servers, and wherein the one or more storage servers being connected to the wireless communications networks;

wherein a Quality-of-Service for transfer of the attachments for the Push-to-X communications is treated differently from other traffic in the wireless communications network; and

wherein the first control message identifies a location for retrieving a first attachment for the first Push-to-X communication stored on the one or more storage servers.

19. A method comprising:

communicating, by a first mobile unit of a plurality of mobile units, with one or more messaging servers, wherein the plurality of mobile units communicate in a Push-to-Talk (PTT) system, wherein the one or more messaging servers provides Push-to-X communications services to the plurality of mobile units over a wireless communications network, wherein the Push-to-X communications comprise a multi-media messaging service, and wherein attachments for the Push-to-X communications are stored on one or more storage servers connected to the wireless communications network;

receiving, by the first mobile unit, a control message for a first Push-to-X communication of the Push-to-X communications from the one or more messaging servers, wherein the control message identifies a location for retrieving a first attachment for the first Push-to-X communication; and

retrieving, by the first mobile unit, the first attachment from the one or more storage servers, wherein a Quality-of-Service for transfer of the first attachments for the first Push-to-X communication is treated differently from other traffic for the first Push-to-X communication in the wireless communications network.

20. The method of claim 19 further comprising forwarding, by the first mobile unit, one or more of the attachments to a second mobile unit of the plurality of mobile units without uploading the one or more of the attachments to the storage servers.

21. The method of claim 19 further comprising receiving, by the first mobile unit, a list of all pending messages received while the first mobile unit was offline in one single signaling transaction with the one or more messaging servers.

22. The method of claim 19, wherein each of the attachments for the Push-to-X communications is stored in a plurality of chunks, and wherein the plurality of mobile units can upload or retrieve individual ones of the plurality of chunks.
