Content Disposition System And Method For Processing Message Content In A Distributed Environment

A User Equipment (UE) device comprising:

• a message generator configured to send a Session Initiation Protocol (SIP) request message via a first IP network;
• and
• a processor configured to process a SIP response message received from a network node via said first IP network, said SIP response message including at least one message body content in said SIP response message's body, wherein said SIP response message includes a content type indicator for said at least one message body content, and the processor further configured to process instructions to provide a treatment for said at least one message body content based on a value of said 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, said treatment, applied by said UE device, comprising one of:
• (i) performing an Emergency Services (ES) call effectuated via a circuit-switched network and (ii) performing a registration and an ES call effectuated via an IP network, wherein the registration involves sending a SIP REGISTER message.

A non-transitory computer readable medium having instructions which are configured, when executed by a processor of a User Equipment (UE) device, for interpreting contents of one or more message bodies, wherein said contents correspond to a content type, said medium comprising:

• a code portion configured to send a Session Initiation Protocol (SIP) request message via a first IP network;
• a code portion configured to process a SIP response message received from a network node via said first IP network, the SIP response message being responsive to said SIP request message and including at least one message body content in said SIP response message's body, wherein said SIP response message further includes a content type indicator for said at least one message body content;
• and
• a code portion configured to provide a treatment for said at least one message body content based on a value of said 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, said treatment, applied by said UE device, comprising one of:
• (i) performing an Emergency Services (ES) call effectuated via a circuit-switched network and (ii) performing a registration and an ES call effectuated via an IP network, wherein the registration involves sending a SIP REGISTER message.
