Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is the method that the terminal in a kind of cellular mobile communication networks realizes virtual multi-user technology, virtual multi-user technology is a kind of at the shared a small amount of radio-cell of a plurality of users of end side, and charge separately for each user, and need not the technology that two-stage dialing is realized conversation at network side.Terminal of the present invention is the communication terminal that has a plurality of telephone interfaces and inner exchanging unit and carry out information interaction by one or more radio-cells and cellular mobile communication networks.
Introduce at first respectively: core net user ID, radio-cell sign and three notions of terminal user identification:
The core net user ID is the sign that mobile communications network manages and charges the terminal use in system side, and is corresponding one by one with the actual user.For example in the CDMA2000 network, this is designated " international travelling carriage identifier " (IMSI, International Mobile Station Identity).
Radio-cell sign is corresponding one by one with each radio-cell in each terminal.At synchronization, a wireless terminal unit can only be set up a wireless channel with network side, is used for a user and calls out and converse.For example in the CDMA2000 network, this sign is " international travelling carriage identifier " (IMSI, International Mobile Station Identity).
The user ID of traditional terminal is exactly the radio-cell sign of this terminal.The major technique of the present invention's innovation is to have broken the one-to-one relationship that " core net user ID " equates with " radio-cell sign ", introduces the notion of " terminal user identification "; Promptly redefine terminal user identification: be made up of terminal wireless unit marks and Customs Assigned Number thereof that this telephone subscriber shares, wherein Customs Assigned Number is the telephone interface serial number of this terminal.Like this, each telephone subscriber just has a plurality of terminal user identifications: be made of a radio-cell identifier combination in this Customs Assigned Number and this terminal respectively, and these a plurality of terminal user identifications are all corresponding with a user ID of this user identity of network system side unique identification.
Referring to Fig. 1, this figure represents between each user in the multiple users of the present invention and its core net user ID mapping relations one to one with various difform legends: the left side expression is m different user in the multiple users of the present invention among the figure, the centre is that (m＞n), the right side is a m different core network user ID in the network system side for n radio-cell in the multiple users of the present invention.A plurality of terminal user identifications that each telephone subscriber has are to be made of this user's Customs Assigned Number and the some radio-cell identifier combination in this terminal respectively, and these a plurality of terminal user identifications are all corresponding with a core net user ID of this user identity of network system side unique identification, promptly adopt both to have identical legend among the figure and represent it.Then, in system, set up the mapping table of terminal user identification and core net user ID, the conversion that utilizes this mapping table that messaging is identified: terminal is issued the message of system, according to mapping table, utilize Customs Assigned Number that the radio-cell sign that receives is converted to the core net user ID by system; System mails to the message of terminal, convert the core net user ID to radio-cell sign and Customs Assigned Number (these operations are referring to applicant's application for a patent for invention " system side in the cellular mobile communication networks realizes the method for virtual multi-user technology ", and its application number is 200510007312.2) by system.Task of the present invention is to finish the conversion of above-mentioned sign and realize conversation in end side.
Because the Customs Assigned Number information that increases will be transmitted in the message between system and the terminal, find after deliberation, the called number field of wireless terminal in the message that system side makes a call is elongated, and increased after the Customs Assigned Number information still in the scope of standard agreement permission, therefore terminal control software can send the called number field that Customs Assigned Number is hidden in the initial call message to network system, system extracts Customs Assigned Number again according to identical hiding rule.Equally, the calling number field that network system sends in the ALERTING message of terminal also is elongated, and after having increased Customs Assigned Number information, its word length is still in the scope of agreement permission, therefore, system can send the calling number field that Customs Assigned Number is hidden in the ALERTING message to terminal.
Certainly, terminal must be consistent with the rule of the hiding Customs Assigned Number of system side.For example: can hide in the mode that spcial character (* or #) adds Customs Assigned Number in the back of called number or calling number, perhaps hide as the prefix of called number or calling number or the mode of suffix with the Customs Assigned Number of fixing length.
Adopting the multiple users of the inventive method, need be each user's SEPARATE APPLICATION independent user sign separately at network side when coming into operation, and is used for independent charging; And each user has separately independently telephone number.By terminal control software each user interface is carried out poll monitoring, according to the principle of first usefulness first, the multiplexing n of the user time-sharing of the m among a Fig. 1 radio-cell is finished the foundation and the removing of conversation.
The improvements of virtual multi-user terminal of the present invention are: when this terminal is breathed out as the outside line caller, Control Software is the called number field of its Customs Assigned Number Information hiding in initial call message, allow the system side can be according to the mapping table of terminal user identification and core net user ID, utilize Customs Assigned Number that the radio-cell sign that receives is converted to the core net user ID, so that charge separately for each virtual multi-user terminal use in system side; And terminal parses called Customs Assigned Number during as the called incoming call of outside line from the caller identification number, and user's ring that control is corresponding makes the calling subscriber need not to dial extension again and just can set up calling, realizes the conversation connection.
Two concrete operations steps when Fig. 2 (A), (B) two figure illustrate terminal of the present invention as outside line caller exhalation and the called incoming call of outside line respectively (need to prove: these two processes all are the normal process flow processs that has under the complete situation of various resources such as available radio-cell and this radio-cell messaging be normal):
After terminal control software detects off-hook, the called number that record off-hook user is dialled, after definite this off-hook user has dialled number, this off-hook user's Customs Assigned Number is hidden in the called number according to hiding rule, command format according to the radio-cell regulation sends to selected radio-cell again, after radio-cell receives this order, dress up initial call message according to the agreement group specified and send to network; Called number field in this initial call message has been hidden Customs Assigned Number information, so that system side is finished the conversion of its corresponding core net user ID according to this terminal iidentification, and is to send ring-back tone and charging separately to this user.
The network system lateral root is determined its Customs Assigned Number information according to the terminal called user of this virtual multi-user in the core net user ID of system side, and it is hidden in an idle radio-cell that sends in the calling number field in the ALERTING message in the target terminal; After this radio-cell is received ALERTING message, send the incoming call display message to terminal control software, include the called Customs Assigned Number that system side is hidden in this caller ID field, after terminal control software is received this message, go out Customs Assigned Number according to hiding Rule Extraction, and directly control corresponding substation ring, realize conversation.All the multi-user's telephone terminal with traditional is identical in the ring control procedure of terminal of the present invention during as the called incoming call of outside line and user's the various operating process of whether answering (comprising unusual flow process), repeats no more here.
Method of the present invention is developed the terminal model machine by the applicant, and has carried out test and implement in its system, and test is successful, has realized goal of the invention.
