In a terminal equipment, when a signal demanding for the detection of the present position of a mating second portable remote terminal is outputted from a first portable remote terminal, nearest a first base station transmits the signal to a server. The server, upon receiving the demand signal, receives the present position of the mating second portable remote terminal by way of a second base station, reads out a map data including the present positions for the first portable remote terminal and the second portable remote terminal from data base and transmits the same to the first and second portable remote terminals.

A mobile station comprising: a preferred roaming list (PRL); a multi-region data structure (MRDS), where the MRDS includes system identification numbers (SIDs) from the PRL; means for scanning and acquiring a system to provide service in a current geographic region; means for marking the acquired system as a current serving system, the current serving system having a SID matching an entry in the PRL; means for detecting that the current serving system matches an entry in the MRDS; means for updating, in response to the detecting and without modification to the PRL, an alternate scan list (ASL), the ASL defining a current union of ail SIDs whose corresponding systems are more preferred than the system currently marked as the current serving system; means for detecting a newly available SID using the ASL, the newly available SID associated with a system servicing a geographic region which overlaps the current geographic region of the current serving system; means for acquiring the system servicing the overlapping geographic region when the newly acquired SID is more preferred than the SID of the system marked as the current serving system, using the MRDS and the PRL, the means for acquiring of the system servicing the overlapping region involves at least one of an intersystem hard handoff and an intrasystem hard handoff of the mobile station to a most desirable system; means for marking the acquired system servicing the overlapping geographic region as the current serving system to redefine the current serving system; and means for re-updating the ASL using the newly acquired SID; wherein the means for scanning and means for detecting the newly available SID involve periodically scanning for a signal indicative of a wireless service. 8. The mobile station of claim 7, wherein systems defined as more preferred in the ASL are systems currently available in a current geographic region the mobile station is in when the ASL is being updated. 9. A process-readable media including programmable instructions operable in a mobile station utilizing a preferred roaming list (PRL) and a multi-region data structure (MRDS), where the MRDS includes system identification numbers (SIDs) from the PRL, the instructions causing the mobile station to: scan and acquire a system to provide service in a current geographic region; mark the acquired system as a current serving system, the current serving system having a SID matching an entry in the PRL; detect that the current serving system matches an entry in the MRDS; update, in response to the detecting and without modification to the PRL, an alternate scan list (ASL), the ASL defining a current union of all SIDs whose corresponding systems are more preferred an the system currently marked as the current serving system; scan, after generating the ASL, to detect a newly available SID using the ASL, the newly available SID associated with a system servicing a geographic region which overlaps the current geographic region of the current serving system; acquire the system servicing the overlapping geographic region when the newly acquired SID is more preferred than the SID of the system marked as the current serving system, using the MRDS and the PRL, to perform at least one of an intersystem hard handoff and an intrasystem hard handoff of the mobile station to a most desirable system; mark the acquired system servicing the overlapping geographic region as the current serving system to redefine the current serving system; and re-update the ASL using the newly acquired SID; wherein the scanning and detecting the newly available SID involve periodically scanning for a signal indicative of a wireless service. ng standby mode, the samples are gathered during paging slots assigned to the mobile. A set of searches are performed on the samples, and if pilot signals are detected additional demodulation is performed to detect paging messages. The resulting set of demodulation data may be combined to increase detection. After a page message has been detected, additional demodulation resources may be activated to processes more complete page messages, or other information channels. In one embodiment of the invention, the searcher includes a demodulator to perform quick page detection without the use of finger elements to reduce idle mode power consumption. om the fixing roller. The heat applying coil is formed by winding a wire so as to have a shape which has parts parallel to the longitudinal direction of the coil supporting member and parts lying along the circumference of the coil supporting member. The winding density of the latter parts is higher than that of the former parts. said image data after said image data is shifted by one bit; calculating an energy of a high frequency component of said image data wavelet-transformed by said first and second wavelet transforming; and outputting said energy as a value that represents said sum. 38. An image processing method as claimed in claim 33, wherein said wavelet transforming is a Haar wavelet transforming. 39. An image processing method as claimed in claim 33, wherein said wavelet transform performed by said wavelet transforming is an overlapped sampling wavelet transform which detects all amounts of change of said image data in a direction in which said wavelet transform is applied. 40. An image processing method as claimed
