Abstract

In one embodiment, a wireless mobile User Equipment (UE) device comprises a message generator configured to send a SIP request message via a first IP network and a processor configured to process a SIP response message received from a network node via the first IP network, the processor further configured to process instructions to provide a treatment for at least one message body content of the SIP response message based on a value of a content type indicator independent of at least one of an absence of a content disposition indicator, a content disposition indicator without a value and a content disposition indicator having a value. The treatment, applied by the UE device, may comprise one of: (i) performing an Emergency Services (ES) call effectuated via a CS network and (ii) performing a registration and an ES call effectuated via an IP network.

Claims

1. A method, comprising:

receiving, from User Equipment (UE) device, a Session Initiation Protocol (SIP) request message via a first IP network by a network node;

transmitting a SIP response message by the network node via the first IP network, the SIP response message being responsive to the SIP request message and including at least one message body content in the SIP response message'"'"'s body, the SIP response message further includes a content type indicator for the at least one message body content; and

wherein the UE device provides, by one or more processors, a treatment for the at least one message body content based on a value of the content type indicator independent of at least one of an absence of a content disposition indicator, a content disposition indicator without a value, or a content disposition indicator having a value, the treatment, applied by the UE device, comprising one of;

(i) performing an Emergency Services (ES) call effectuated via a circuit-switched network;

or (ii) performing a registration and an ES call effectuated via an IP network, wherein the registration involves sending a SIP REGISTER message.

2. The method of claim 1, wherein the SIP response message'"'"'s body comprises at least one directive.

3. The method of claim 1, wherein the SIP response message'"'"'s body comprises an Extensible Markup Language (XML) document.

4. The method of claim 1, wherein the content type is an XML media type or an XML-Based Media Type.

5. The method of claim 4, wherein the XML media type or the XML-Based Media Type is defined by an XML schema.

6. The method of claim 1, wherein the content disposition indicator is provided in a Content-Disposition header field.

7. The method of claim 6, wherein the content type indicator is provided in a Content-Type header field.

8. The method of claim 7, wherein each of the Content-Disposition header field and the Content-Type header field takes on a value comprising textual information.

9. The method of claim 1, wherein the IP network comprises a second IP network.

10. The method of claim 1, wherein the treatment comprises providing an indication to a user.

11. A network node, comprising:

a receiver configured to receive, from User Equipment (UE) device, a Session Initiation Protocol (SIP) request message via a first IP network;

a transmitter configured to transmit a SIP response message by the network node via the first IP network, the SIP response message being responsive to the SIP request message and including at least one message body content in the SIP response message'"'"'s body, the SIP response message further includes a content type indicator for the at least one message body content; and

wherein the UE device provides, by one or more processors, a treatment for the at least one message body content based on a value of the content type indicator independent of at least one of an absence of a content disposition indicator, a content disposition indicator without a value, or a content disposition indicator having a value, the treatment, applied by the UE device, comprising one of;

(i) performing an Emergency Services (ES) call effectuated via a circuit-switched network;

or (ii) performing a registration and an ES call effectuated via an IP network, wherein the registration involves sending a SIP REGISTER message.

12. The network node of claim 11, wherein the SIP response message'"'"'s body comprises at least one directive.

13. The network node of claim 11, wherein the SIP response message'"'"'s body comprises an Extensible Markup Language (XML) document.

14. The network node of claim 11, wherein the content type is an XML media type or an XML-Based Media Type.

15. The network node of claim 14, wherein the XML media type or the XML-Based Media Type is defined by an XML schema.

16. The network node of claim 11, wherein the content disposition indicator is provided in a Content-Disposition header field.

17. The network node of claim 16, wherein the content type indicator is provided in a Content-Type header field.

18. The network node of claim 17, wherein each of the Content-Disposition header field and the Content-Type header field takes on a value comprising textual information.

19. The network node of claim 11, wherein the IP network comprises a second IP network.

20. The network node of claim 11, wherein the treatment comprises providing an indication to a user.
