    摘要: The present invention relates to a method for establishing a service in a first frequency in a communication network, wherein the first frequency does not support the service or supports it in a limited way, the method comprises the following steps: determining the service to be established, re-selecting or redirecting to a second frequency that is suitable for the service, so as to carry out the service in the second frequency. The present invention also relates to user equipment and a network apparatus for establishing a service in a first frequency in a communication network, wherein the first frequency does not support the service or supports it in a limited way. According to the present invention, a non-MBMS service may be established in the MBMS dedicated frequency, so as to carry out the non-MBMS service in the normal frequency.

    摘要: A physical method for maintaining the freshness of vegetables and fruits via the technology of the optical signal and optical signal generator are disclosed. By adopting the computer programmable pulsed scanning signal generator, it controls the light-emitting device mounted with red, green and blue light sources group to generate optical signal with pulsed or pulsed periodical scanning combined spectrum. The optical signal irradiates the fresh-cut fruits and vegetables preserved in the storage assembly at room temperature or at controlled temperature and humidity. By regulating the optical signal with periodical pulsed spectrum or pulsed scanning spectrum or periodical pulsed scanning combined spectrum, the irradiated vegetables and fruits obtain photon energy needed in light reactions of photosynthesis from the lighting environment of artificial optical signal which is in bright and dark periodic variation. The metabolism of the cellular tissue is recovered and maintained, and the growth inertia is kept at slow speed. It effectively prolongs the freshness state of vegetables and fruits which are preserved in the storage assembly.
