Abstract: A method includes attaching to a Packet Data Network (PDN) supporting services over a long term evolution (LTE) network to establish a first network connection. The method includes connecting to a wireless local area network, e.g. a WiFi network, to establish a second network connection. The method further includes launching an application accessing at least one of the supported services and receiving a request from the application to switch between the first and second network connections, according to the supported service, e.g. a policy associated with the service. Switching from the first network connection to the second network connections includes connecting to the PDN via an evolved Packet Data Gateway (ePDG).

Abstract: With an introducing catheter (A) accommodated by a diagnostic-therapeutic catheter (B), the necessity of a sheath is eliminated to render the diagnostic-therapeutic catheter (B) as large as the sheath. This enables a manipulator to fully treat a patient with the use of diagnostic-therapeutic catheter (E). With the elimination of the sheath, the diagnostic-therapeutic catheter (B) is directly inserted into tubular human organs (e.g., radial artery and brachial artery). Coaxially provided are inner and outer tubes 12, 13 with the diagnostic-therapeutic catheter (B) to have an annular space 14, at least a part of which forms a drug-releasable open end 15 exposed to a shaft portion 11. The outer tube 13 has a plurality of drug-releasable side holes 9 to release an anti-spasmodic drug toward a blood vessel through the drug-releasable open end 15.
