Fig. 1 shows one by the defined down link multiframe of ESTI (multi-frame) channel format example, multiframe 10 comprises 51 time division multiple access frames (TDMA frame), and this channel format standard goes out the sequential of the burst sequence (burst sequence) of each channel that sends the base station.F represents the burst sequence of frequency correction channel, and what wherein transmit is the string ripple signal of a fixed frequency, makes that the mobile device recoverable in the covering scope of base station arrives and the identical carrier frequency of base station use, reaches the synchronous of frequency.S represents the burst sequence of synchronizing channel, putting down in writing base station identity code (Base Station Identity Code, BSIC), and the frame number of the simplification of the present time division multiple access frame in base station (Reduced Frame Number, RFN), make mobile device to reach the synchronous of time with the base station.B represents the burst sequence of Broadcast Control Channel, is putting down in writing radio link configuration, synchronizing information of base station etc.C represents the burst sequence of common control channel, wherein according to the definition of ESTI, direct access communications channels, access allow the burst sequence of channel, calling channel and notification channel to transmit at the time division multiple access frame of common control channel, therefore in down link multiframe channel format 10 as shown in Figure 1, the time division multiple access frame of common control channel may comprise that access from the base station allows information, (Paging Indicator, PI) indication information etc. grouied busy in information or voice to call out indication.It should be noted that, learn the frame number of the present time division multiple access frame in base station when mobile device after, can set up the synchronous of sequential with the base station, and set up out multiframe channel format with base station synchronization in the mobile device end, thus, mobile device can receive corresponding burst sequence at specific time point, with the information of correct each time division multiple access frame of reception.
Fig. 2 shows the inside structure according to the described mobile device 100 of embodiments of the invention, and mobile device 100 comprises wireless transceiver 101, first subscriber identification module (SIM 1), 102, second subscriber identification module (SIM 2) 103 and fundamental frequency processor 104.Wireless transceiver 101 comprises conveyer and receiving system (not shown), sends out in order to the carrier frequency that fundamental frequency signal is stated from online base station, and the high-frequency signal frequency reducing that receives is become fundamental frequency signal, is resent to fundamental frequency processor 104.Fundamental frequency processor 104 is in order to handle the fundamental frequency signal of mobile device 100 inside, to comprise responsible signal interpretation, sequencing control and other Digital Signal Processing etc.Fundamental frequency processor 104 also comprises micro-control unit (Micro ControlUnit, MCU) 105, receive the data of unity logic channel in order to control wireless transceiver 101 in the set time, and these data only belong to subscriber identification module 102 and 103 one of them all.
Fig. 3 is a kind of network topology example.According to embodiments of the invention, subscriber identification module 102 and 103 is shared the fundamental frequency processor 104 and wireless transceiver 101 in the mobile device, therefore subscriber identification module 102 and 103 can be passed through wireless transceiver 101 respectively to base station 301 and base station 302 registrations, online, and respectively by base station 301 and base station 302 transmitted in both directions voice and data packets.It should be noted that subscriber identification module 102 can adhere to different telecommunications companies separately with 103, as shown in Figure 3.In Fig. 3, base station 301 belongs to communication network 303, and base station 302 belongs to communication network 304, and the subscriber identification module 102 of mobile device 100 can be online to base station 301, and subscriber identification module 103 can be online to base station 302.In addition, as known for the skilled artisan, subscriber identification module 102 and 103 also can belong to same telecommunications company, and subscriber identification module 102 and 103 also may be online to the different base station of same communication network in the case, even same base station.Therefore above explanation is not in order to limit the present invention.
Behind online respectively upward base station 301 of mobile device 100 and base station 302, can obtain the frame number of base station 301 and base station 302 present time division multiple access frames respectively by the burst sequence content that broadcast the base station.Then, the time sequence control device (not shown) of micro-control unit 105 inside can be set up out the multiframe channel format synchronous with base station 301 and base station 302 respectively, in order to the base station reach sequential synchronously.Yet, since the 101 same times of wireless transceiver can only receive the data of a logic channel.Therefore, in the process of channel scheduling, micro-control unit 105 can give base station 301 the priority memory access weight different with each logic channel of base station 302, relatively two pairing priority memory access weights of logic channel in the given time and when overlapping situation, and one higher data of priority memory access weight in two logic channels of control wireless transceiver 101 complete receptions.
Fig. 4 shows a kind of overlapping situation example 40, wherein multiframe channel format 401 is the synchronous multiframe channel format in mobile device 100 inner set ups and base station 301, and multiframe channel format 402 is the synchronous multiframe channel format in mobile device 100 inside set ups and base station 302.As shown in the figure, mobile device 100 is estimated the burst sequence by wireless transceiver 101 301 receipt of call channels from the base station in time interval T1, and estimate the burst sequence by wireless transceiver 101 302 reception Broadcast Control Channel from the base station in time interval T2, wherein time interval T1 and T2 comprise software or hardware time of time of wireless transceiver 101 and fundamental frequency processor 104 inside, and as shown in the figure time interval T1 and T2 to have a part-time interval overlapping.In this situation, because the burst sequence of calling channel may be carried the information of calling out indication (PI) secretly, and the burst sequence of Broadcast Control Channel can regularly repeat to transmit, therefore, in the process of channel scheduling, micro-control unit 105 can give base station 301 higher priority weight at time interval T1, and control wireless transceiver 101 is at four burst information P0～P3 of the complete receipt of call channel of time interval T1.
When overlapping situation took place, the foundation of giving priority weight can be according to the kind of channel or according to the time sequencing of the burst sequence that overlaps.Under as shown in FIG. 4 the situation of example, micro-control unit 105 thinks that calling channel may carry important information secretly, therefore gives the priority weight that calling channel is higher than Broadcast Control Channel.Perhaps micro-control unit 105 also can be selected complete reception start time point burst sequence early, as the calling channel burst sequence among Fig. 4 according to the start time point of the burst sequence of two channels.On the other hand, micro-control unit 105 also can be given priority weight randomly, perhaps in turn higher priority weight is given the two burst sequences that overlap one, perhaps the telecom operators of the comparatively preference that sets according to the user give its corresponding higher priority weight of burst sequence.
According to embodiments of the invention, behind four burst information P0～P3 of wireless transceiver 101 complete receipt of call channels, micro-control unit 105 is gone back may command wireless transceiver 101 continues to receive Broadcast Control Channel at time interval T4 burst information B1～B3.Because in gsm system, the data that transmit the base station are handled through specific chnnel coding and staggered (interleaving), so still the have the ability burst information B1～B3 of the Broadcast Control Channel by a part of fundamental frequency processor 104 deciphers out the broadcast message of base station.
