Referring now to Fig. 3, shown on the figure according to method of the present invention.In square A, suppose that travelling carriage 10 had before signed in to BMI32, and the DCCH that is in first system be stationed state (IS-136.1, Section6.2.3).In square B, travelling carriage 10 retunes transmitter 14 and receiver 16, and uses ACC to send log on command to second system.
In this respect, it should be noted that ACC and DCCH can be the control channels of same system (for example SID), or they can be the control channels of two different systems (for example two SID).Like this, as used herein, term " first system " and " second system " are considered to comprise all both of these cases, because instruction of the present invention is equally applicable to both of these case.
In square C, whether travelling carriage 10 judgements log on command acknowledge message in certain time interval is received from second system.If receive the order acknowledge message, then control enters square D, and travelling carriage 10 quarters at ACC in a usual manner therein.Yet if determine in square C: travelling carriage 10 does not receive order acknowledge message (even this message has been sent by second system), and control enters square E, and travelling carriage 10 is provided with order acknowledgement indicator (OCFLAG) in memory 24 therein.Travelling carriage enters into the program (square F) of Search Control channel then, and whether when finding a control channel (square G), making about control channel is the judgement (square H) of digital control channel.If control channel is not a DCCH (that is, control channel is an Analog Control Channel), then control turns back to square B, sends log on command on the new ACC that obtains.If yet new control channel is a DCCH, control enters square I.
At square I, when when DCCH is stationed state (IS-136.1Section6.2.3, DCCHCampingState (D3)), travelling carriage 10 is made about whether there being the judgement of one of a plurality of jump conditions.To present embodiment of the present invention most interested be that ACC is to the DCCH jump condition.Usually, in current power supply cycle period, no matter when to attempt to obtain the login in a service on the DCCH and its a last success be on ACC the time to travelling carriage 10, just has this condition.
According to present embodiment of the present invention, ACC is modified to also comprise judging whether travelling carriage 10 successfully sends log on command on ACC to the DCCH jump condition, does not confirm but receive order.This condition is reflected in the OCFLAG state that before is provided with in square E.Like this, in square I, travelling carriage 10 is made about whether the judgement of OCFLAG is set.If it's not true, then condition does not satisfy, and control turns back to square A, and therein, travelling carriage 10 remains on DCCH and is stationed state.Yet, in square I, the words that judgement is (OCFLAG is set up), in square J, travelling carriage 10 starts ACC to the DCCH jump condition, and calls DCCH logging program (Section6.3.7) in square K, so that (again) signs in to first system.Then, control the DCCH that enters square A and be stationed state.
By signing in to first system of BMI, send to any paging of travelling carriage 10 and other message and not it is believed that it is to send on the ACC that is stationed of travelling carriage 10, send but change on the DCCH of first system of BMI32.In this case, except at the square E-K of execution graph 3 needed normal time, travelling carriage 10 does not block from system business.
Though be to be described for attempting to login under the situation on the ACC, scope of the present invention comprises that also these instructions of the present invention are applied to DCCH is stationed state (D3) super band jump condition (Section6.2.3), and thereby provides independent sign (for example HBFLAG) successfully to send log messages with expression travelling carriage 10 but do not receive from different super band that login is accepted or the login refuse information.Therefore, shown method is corrected thereupon in Fig. 3 flow chart.Usually super band is meant another frequency range in the two-band system.For example in two-band DAMPS system, if travelling carriage is logined in the 800MHz frequency range, then the 1900MHz frequency range can be considered to super band, and vice versa.Instruction of the present invention also is applied to travelling carriage to be realized and signs in to different SID, and RSID and PSID attempt not case of successful.
Further in accordance with the teachings of the present invention, response to additional information state (IS-136.2Section2.6.2.1) also can be corrected, if thereby make that the previous successful login of travelling carriage is at Analog Control Channel, and travelling carriage successfully sent log messages but do not received from DCCH immediately before obtaining on the current ACC service that login is accepted or the login refusal, and then it inserts task (seeing IS-136.1Section6.2.3) by means of the system that enters by a login indication and initiates a spontaneous login (shifting login).Another sign in the memory 24 can be used to (or being used to again) this purpose.
Though be in the context of preferred embodiment, to be described, should be understood that those skilled in the art can carry out the multiple correction for these instructions.Therefore, wherein can make various changes in the form and details and do not deviate from scope and spirit of the present invention though the present invention shows particularly for preferred embodiment and describes, and should see.
