2. Background • Background The working document of M.[IMT.UPDATE] has been being studied and revised in the last three meeting (8th to 10th meeting) of WP5D. At the 10th meeting the working document on IMT.UPDATE was developed around 20 pages of main body and necessary annex.

3. Contents of Possible Contribution from CJK CJK White Paper contains the information specific to the Region 3. Therefore, JAPAN proposes that CJK supportsthe White Paper and provides the useful information on Region 3 as follows: M.[IMT.UPDATE] Section 2：“Traffic and user penetration information of existing Mobile Broadband deployments (until 2011)” CJK can provide the appropriate information to section 1of White Paper. (Editor’s chairman expects the data such as Figure 3 or Figure 4 as regional cases.) M.[IMT.UPDATE] Section 3：“Trends contributing to increased demand for mobile broadband” CJK can provide the appropriate information on section 2.1 of White Paper. M.[IMT.UPDATE] Section 4 : “Updated Mobile Broadband forecasts up to 2020 and beyond”” CJK could provide the regional traffic information on section 2.3 of White Paper and other appropriate information of White Paper.

To add the description on “Action Plan for Future Wireless Broadband reported by JAPAN Administration to section 3.9 of M.[IMT.UPDATE] To provide the actual data related to BHT(Busy Hour Traffic) Each operator designs the network capacity that can accomodate the peak traffic (BHT). So as to calculate the necessary bandwith, the BHT should be one of important parameters.
