Wireless device media control session
View Patent ↗A wireless device transmits, to a second wireless device via an internet protocol multimedia subsystem (IMS) network entity, a session initiation protocol (SIP) invitation. The SIP invitation may comprise a session description protocol (SDP). The SDP may comprise a media type and one or more attributes. The media type may identify a protocol for controlling operational orders. The controlling operational orders may comprise at least: mechanical operational orders; and electrical operational orders. The one or more attributes may identify a format of the protocol to establish a SIP session. The wireless device may receive, from the second wireless device via the IMS network entity, a SIP confirmation for the SIP session. The wireless device may control the second wireless device employing the controlling operational orders identified by the media type.
1. A method comprising:
transmitting, by a first wireless device to a second wireless device via an internet protocol multimedia subsystem (IMS) network entity, a session initiation protocol (SIP) invitation to establish a SIP session, the SIP invitation comprising a session description protocol (SDP) comprising an application media type identifying a protocol for controlling operational orders, wherein:
a multipurpose internet mail extension (MIME) type for the application media type is registered by an internet assigned number authority (IANA) and is a media burst operation protocol; and
the controlling operational orders comprise:
mechanical operational orders;
electrical operational orders; and
one or more attributes identifying a format of the protocol;
receiving, by the first wireless device from the second wireless device via the IMS network entity, a SIP confirmation for the SIP session; and
controlling, by the first wireless device, the second wireless device employing the controlling operational orders identified by the application media type.
2. The method according to claim 1 , wherein the SDP conveys the application media type by not knowing the format.
3. The method according to claim 1 , wherein the SDP identifies at least:
one or more port numbers identifying one or more ports for the application media type; and
a transport protocol identifying an employed protocol for transportation of the application media type.
4. The method according to claim 3 , wherein the transport protocol is a user datagram protocol (UDP).
5. The method according to claim 1 , wherein the SIP session comprises
a mission critical video session; or
a mission critical data session.
6. The method according to claim 1 , wherein the first wireless device and the second wireless device are:
mission critical video wireless devices; or
mission critical data wireless devices.
7. The method according to claim 1 , wherein the first wireless device is registered to the IMS network entity as a dispatcher.
8. The method according to claim 1 , wherein the second wireless device is registered to the IMS network entity as a surveillance camera.
9. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors,
cause the wireless device to:
transmit, to a second wireless device via an internet protocol multimedia subsystem (IMS) network entity, a session initiation protocol (SIP) invitation to establish a SIP session, the SIP invitation comprising a session description protocol (SDP) comprising an application media type identifying a protocol for controlling operational orders, wherein:
a multipurpose internet mail extension (MIME) type for the application media type is registered by an internet assigned number authority (IANA) and is a media burst operation protocol; and
the controlling operational orders comprise:
mechanical operational orders;
electrical operational orders; and
one or more attributes identifying a format of the protocol;
receive, from the second wireless device via the IMS network entity, a SIP confirmation for the SIP session; and
controlling the second wireless device employing the controlling operational orders identified by the application media type.
10. The wireless device according to claim 9 , wherein the SDP conveys the application media type by not knowing the format.
11. The wireless device according to claim 9 , wherein the SDP identifies at least:
one or more port numbers identifying one or more ports for the application media type; and
a transport protocol identifying a protocol for transportation of the application media type.
12. The wireless device according to claim 11 , wherein the transport protocol is user datagram protocol (UDP).
13. The wireless device according to claim 9 , wherein the SIP session comprises
a mission critical video session; or
a mission critical data session.
14. The wireless device according to claim 9 , wherein the wireless device and the second wireless device are
mission critical video wireless devices; or
mission critical data wireless devices.
15. The wireless device according to claim 9 , wherein the wireless device is registered to the IMS network entity as a dispatcher.
16. The wireless device according to claim 9 , wherein the second wireless device is registered to the IMS network entity as a surveillance camera.
