摘要:
The problem of the invention is to provide a resin composite electrolytic copper foil having further improved heat resistance and improved plate adhesion strength when plated after desmear treatment in the work process of an additive method. The solution is to form a roughened surface having a plurality of minute projections, a surface roughness (Rz) within a range of 1.0 μm to 3.0 μm and a lightness value of not more than 30 on one surface of an electrolytic copper foil, and form a layer of a resin composition containing a block copolymerized polyimide resin having a structure that imide oligomers of a first structural unit and a second structural unit are bonded alternately and repeatedly on the roughened surface.

After a first base station connects to a first mobile terminal, a first GW (gateway) receives a request for connection between the first mobile terminal and a second GW and identifiers of the second GW and the first mobile terminal and transmits identifiers of the first mobile terminal and the first GW to the second GW. The second GW transmits an MPLS allocation flag to the first GW. The first GW transmits an MPLS allocation signal including an identifier of the first mobile terminal to the second GW via a second NW (network) apparatus. The first base station receives an identifier of the first GW and the MPLS allocation flag from the first GW via a management server and transmits the MPLS allocation signal including the identifier of the first mobile terminal to the first GW via a first NW apparatus.
