The objective of this work item is to update lawful interception specifications for the latest Rel-10<br />
architecture and services as described in the above justification.<br />
The enhancements to specifications TS 33.106, TS 33.107 and TS 33.108 address the additional work to<br />
specify the HI2 (Intercepted Related Information) and the HI3 (Content) interfaces to delivery to the Law<br />
Enforcement Monitoring Facilities for 3G networks for Rel-10.<br />
Details, for the common IMS and the TISPAN LI needs, have to be specified. Dynamic triggering of<br />
interception between different domains should be investigated.<br />
7.4 RELEASE‐INDEPENDENT FEATURES<br />
While most 3GPP features are introduced in a specific release (e.g. Rel-99, Rel-5, Rel-6, etc.), there are<br />
some features that can be introduced in a release-independent fashion. The main features that are<br />
release-independent are the introduction of new frequency bands and the carrier configurations for DC-<br />
HSPA and LTE CA. The significance of these features being release-independent is that they can be<br />
standardized after a release is completed but can still be applicable to the earlier release.<br />
This means that if a new frequency band or DC-HSPA/CA configuration has been approved in 3GPP for<br />
inclusion in the specifications (i.e. co-existence and interference studies have been performed and<br />
agreed to not introduce performance degradations to adjacent frequency bands), then these can be<br />
applicable to any release and not have to wait for the completion of the next big 3GPP Release. These<br />
updates can occur with the approval of the RAN plenary, more or less every quarter, by updating 3GPP<br />
TS 36.307.<br />
7.4.1 BAND COMBINATIONS FOR LTE‐CA<br />
Specifically for the LTE-CA combinations, a large number of combinations will need to be studied in order<br />
to support the needs of the various operators throughout the world (see 3GPP R4-101062). It is clear that<br />
the large amount of work needed to complete this will not be done before the plan release date for LTE<br />
Rel-10. Consequently, it was decided that in LTE Rel-10, RAN 4 will complete the specification for a set<br />
of generic scenarios (Tables 7.2 and 7.3). It was also agreed that the additional CA scenarios will be<br />
completed in a release-independent fashion.<br />
