Abstract

An apparatus for reducing session related message size includes a processing element. The processing element may be configured to determine a domain-wide unique identifier and generate a message including a first field for identifying a message sequence associated with the message and a second field including a tag. The second field including the tag may be associated with an identifier of a source or recipient of the message. At least one of the first and second fields may be without data. The processing element may be further configured to include, in the message, a third field comprising at least the domain-wide unique identifier. The third field may be associated with data otherwise intended for the first and second fields.

Claims

1. A method for generating a session related message comprising:

determining a domain-wide unique identifier;

generating a message including a first field for identifying a message sequence associated with the message and a second field including a tag, the second field including the tag being associated with an identifier of a source or recipient of the message, such that at least one of the first and second fields is without data; and

including, in the message, a third field comprising at least the domain-wide unique identifier, the third field being associated with data otherwise intended for the first and second fields.

2. A method according to claim 1, wherein, if the message is a first message of a message sequence, determining the domain-wide unique identifier comprises determining a new unique domain-wide unique identifier.

3. A method according to claim 1, wherein, if the message is not a first message of a message sequence, determining the domain-wide unique identifier comprises determining the domain-wide unique identifier based on a prior domain-wide unique identifier.

4. A method according to claim 1, wherein generating the message comprises omitting the domain-wide unique identifier from the first field comprising a Call-ID field and the second field comprising a tag associated with a “

From”

or “

To”

field, and wherein including the third field comprises including the domain-wide unique identifier in a combined field which, when received by another device, is recognizable as including at least a portion of the data otherwise intended for the first and second fields.

5. A method according to claim 1, further comprising an initial operation of determining whether the message is to be sent over a signaling channel and only executing the operations of the method of claim 1 in response to a determination that the message comprising a Session Initiation Protocol (SIP) message is to be sent over the signaling channel.

6. A computer program product for generating a session related message, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for determining a domain-wide unique identifier;

a second executable portion for generating a message including a first field for identifying a message sequence associated with the message and a second field including a tag, the second field including the tag being associated with an identifier of a source or recipient of the message, such that at least one of the first and second fields is without data; and

a third executable portion for including, in the message, a third field comprising at least the domain-wide unique identifier, the third field being associated with data otherwise intended for the first and second fields.

7. A computer program product according to claim 6, wherein the first executable portion includes instructions for determining a new unique domain-wide unique identifier if the message is a first message of a message sequence.

8. A computer program product according to claim 6, wherein the first executable portion includes instructions for determining the domain-wide unique identifier based on a prior domain-wide unique identifier if the message is not a first message of a message sequence.

9. A computer program product according to claim 6, wherein the second executable portion includes instructions for omitting the domain-wide unique identifier from the first field comprising a Call-ID field and the second field comprising a tag associated with a “

From”

or “

To”

field, and wherein the third executable portion includes instructions for including the domain-wide unique identifier in a combined field which, when received by another device, is recognizable as including at least a portion of the data otherwise intended for the first and second fields.

10. A computer program product according to claim 6, further comprising a fourth executable portion for an initial operation of determining whether the message is to be sent over a signaling channel, wherein the first, second and third executable portions are only executed in response to a determination that the message comprising a Session Initiation Protocol (SIP) message is to be sent over the signaling channel.

11. An apparatus for generating a session related message, the apparatus comprising a processing element configured to:

determine a domain-wide unique identifier;

generate a message including a first field for identifying a message sequence associated with the message and a second field including a tag, the second field including the tag being associated with an identifier of a source or recipient of the message, such that at least one of the first and second fields is without data; and

include, in the message, a third field comprising at least the domain-wide unique identifier, the third field being associated with data otherwise intended for the first and second fields.

12. An apparatus according to claim 11, wherein the processing element is configured to determine a new unique domain-wide unique identifier if the message is a first message of a message sequence.

13. An apparatus according to claim 11, wherein the processing element is configured to determine the domain-wide unique identifier based on a prior domain-wide unique identifier if the message is not a first message of a message sequence.

14. An apparatus according to claim 11, wherein the processing element is further configured to:

omit the domain-wide unique identifier from the first field comprising a Call-ID field and the second field comprising a tag associated with a “

From”

or “

To”

field; and

include the domain-wide unique identifier in the third field comprising a combined field which, when received by another device, is recognizable as including at least a portion of the data otherwise intended for the first and second fields.

15. An apparatus according to claim 11, wherein the processing element is further configured for an initial operation of determining whether the message is to be sent over a signaling channel, and wherein the processing element is configured to perform the operations of claim 11 only in response to a determination that the message comprising a Session Initiation Protocol (SIP) message is to be sent over the signaling channel.

16. A method for processing a session related message comprising:

receiving a session related message including a first field for identifying a message sequence associated with the message and a second field including a tag, the second field including the tag being associated with an identifier of a source or recipient of the message, at least one of the first and second fields being without data;

From”

or “

To”

field, and inserting the domain-wide unique identifier concatenated with an address of the source of the message into the first field comprising a Call-ID field.
