Standards Alignment

The following sections describe how WebLogic SIP Server complies with various specifications and RFCs:

 

Overview of WebLogic SIP Server Standards Alignment

WebLogic SIP Server is developed with special attention to Internet Engineering Task Force and 3rd Generation Partnership Project specifications. Feature development is prioritized according to general market trends, both observed and predicted. In cases where certain specifications are obsolete or where Internet drafts are formalized as ‘Request For Comments’ standards, WebLogic SIP Server places priority on compliance with those specifications. In cases where specifications are part of a larger release plan, as with the 3GPP, BEA prioritizes compliance with the latest ratified release (in this case, Release 6). This should not be presumed to mean that the product is not compliant with subsequent versions of component specifications, although this document does not summarize compliance with those specifications.

 

Java Sun Recommendation (JSR) Standards Compliance

WebLogic SIP Server is compliant with J2EE versions 1.4 and 1.3 and the corresponding J2EE component specifications. See Standards Support in the WebLogic Server 9.2 documentation for more details.

WebLogic SIP Server is further enhanced by the addition of a SIP Servlet container defined by JSR 116: “SIP Servlet API.”

WebLogic SIP Server has executed all related Test Compatibility Kits (TCKs) and has met the formal requirements established by Sun Microsystems for formal public statements of compliance.

 

IETF RFC Compliance

The following table lists the WebLogic SIP Server level of compliance to common Internet Engineering Task Force (IETF) Requests for Comment (RFCs) and Internet drafts. The level of compliance is defined as follows:

 

3GPP R6 Specification Conformance

Table 5-2, 3GPP R6 Specification Conformance, on page 5-12 summarizes the ability of WebLogic SIP Server to support implementation of the enablers or application functions identified by each applicable 3GPP Release 6 specification.

Other than the exceptions noted, WebLogic SIP Server does not impose any restrictions on implementing applications or functions that are compliant with those associated with the Application Server entity described in the specification. In some cases, applications must implement support for SIP methods or headers. The default behavior of the WebLogic SIP Server Sip Servlet Container is to pass unrecognized headers, request methods and payloads to SIP Servlets using normal SIP Servlet API procedures.

  • No comments.
3GPP TS 24.229: “IP Multimedia Call Control Protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 (Release 6)”
  • WebLogic SIP Server does not enforce the requirement that only one p-charging-function-address header per SIP request as described in sub-section 5.7.1.2. WebLogic SIP Server does enforce uniqueness.
  • WebLogic SIP Server does not provide privacy support as described in sub-section 5.7.3.
3GPP TS 23.141: “Presence Service; Architecture and Functional description (Release 6)”
  • WebLogic SIP Server does not natively support the Ph (MAP), Pl (LIF-MLP), Px (DIAMETER Cx/Dx), Pg (phase 4, 3GPP Release 5),Pc (CAMEL phase 4, 3GPP Release 5) or Pr, Pk and Pp (RADIUS) reference points.
  • WebLogic SIP Server does not support IPv6 as required for the Presence User Agent (Peu) reference point as required in sub-section 4.3.1.
