A method and apparatus for establishing a radio bearer of a point-to-multipoint multimedia service by utilizing a reference configuration of radio bearer parameters for quickly establising a radio bearer when a mobile terminal moves between cells. By configuring radio bearer parameters for a specific point-to-multipoint service by utilizing a reference configuration such that the same, or equal value, protocol and channel parameters are set for each cell, different cells in a communication system in which a specific point-to-point service is provided are able to configure the radio protocol entities, channels, and radio bearer at the same time by utilizing the same parameter values, thereby minimizing delay in establishing a radio bearer and minimizing data loss occurring during handover, conserving network resources, and enhancing reception performance via soft combining.

In a Conductor-Backed Coplanar Waveguide (CBCPW) structure, an effective dielectric constant of a parallel plate waveguide is higher than that of a Coplanar Waveguide (CPW), so that a parallel plate leakage is generated. To reduce the parallel plate leakage, the present invention provides air cavities, whose dielectric constant is low, in a multilayer circuit so that the effective dielectric constant of the parallel plate waveguide of the CBCPW structure can be lowered.

A magnetic phone case includes a phone pouch, a magnet, a notch, and a phone insertion opening. The phone pouch that secures the mobile phone includes a rear panel, a front panel, and a lateral panel, wherein the front panel is connected to the rear panel by the lateral panel. The phone insertion opening is delineated within the front panel, the rear panel, and the lateral panel so that the user can insert the mobile phone. The magnet is internally connected within the front panel to magnetically attached and securely hold the mobile phone within the phone pouch. The notch traverses into the front panel about the phone insertion opening thus allowing the user to outwardly push out the front panel so that the magnetic attachment can be separated and mobile phone can be pulled out.
