Abstract

A Web service of a network entity can be invoked using reduced messages. A redundancy agreement message is sent to the network entity. The redundancy agreement message describes a redundancy agreement for invoking the Web service using reduced messages. A reduced message is formed based on the redundancy agreement and a non-redundant portion of a Web service message that may be used for invoking the Web service. The reduced message is sent to the network entity and the Web service is invoked at the network entity based on the reduced message and the redundancy agreement.

23. The apparatus according to claim 21, wherein the reduced message comprises a SOAP message.

24. The apparatus according to claim 21, wherein the redundancy agreement message comprises a SOAP message.

25. The apparatus according to claim 21, wherein the redundancy agreement message comprises a binary formatted message.

26. The apparatus according to claim 21, wherein the redundancy agreement comprises a mapping of identifiers to content strings, wherein the content strings are based on a non-redundant portion of a Web service message configured for invoking the Web service.

27. The apparatus according to claim 21, wherein the processor is further configured to receive a redundancy agreement reply message in response to the redundancy agreement message.

28. The apparatus according to claim 27, wherein the redundancy agreement reply message comprises a suggested modification to the redundancy agreement.

29. The apparatus according to claim 21, wherein the redundancy agreement message is included in a non-reduced Web service message.

30. The apparatus according to claim 21, wherein the reduced message includes one or more XML processing instructions indicating a non-redundant portion of a Web service message configured for invoking the Web service.

31. The apparatus according to claim 21, wherein the processor is further configured by the redundancy agreement module to determining a quality measurement based on sizes of the reduced message and a Web service message configured for invoking the Web service.

32. The apparatus according to claim 31, wherein the quality measurement is used to determine whether to utilize the redundancy agreement.
