Embodiment Construction

[0040] According to the basic concept of the present invention, the method of applying the sensing pilot channel to collect network information and broadcasting to the terminal of the present invention includes applying a specific wireless access technology to the out-of-band sensing pilot channel, and using the global channel Broadcast out-of-band network information, which includes country code, operator code, wireless access network type, and corresponding operating frequency band. The out-of-band sensing pilot channel and the in-band sensing pilot channel form a joint pilot channel network architecture.

[0041] The global common channel used by the out-of-band pilot channel is a set of out-of-band sensing pilot channel frequency points, and each country provides free frequency points available for use in the country to form the out-of-band sensing pilot channel according to their national spectrum resource allocation strategy and spectrum occupancy. Frequency point set, out-...

Abstract

This invention discloses one method to apply sensor guide frequency channel collection network information to terminal broadcast, which comprises the following steps: the signal channel uses outer sensor guide frequency signal channel for frequency collection to collect each point of frequency outer network information; the inner sensor signal channel is of local area broadcast inner network information stored in wireless interface network to form cross guide frequency signal channel network structure.

Description

Technical field [0001] The present invention relates to a method for collecting and broadcasting network information in a heterogeneous communication system, in particular to a method for collecting network information by applying a perceptual pilot channel and broadcasting to a terminal. Background technique [0002] At present, the telecommunications world is undergoing some fundamental changes to adapt to the increasing and changing user needs. The most interesting research point is in the field of wireless communication, the main purpose is to achieve faster and easier communication. The existing wireless communication technology includes a variety of wireless access standards: GSM system, GPRS system, UMTS system, broadband wireless access system, wireless local area network, digital image broadcasting system (DVB), CDMA2000 system, PHS system, satellite communication, satellite Positioning and various short-range communication standards. Due to the difference in design go...
