Embodiment
The scheme that adopts physical number to separate with logical number in the present invention is a user logical number and physical number is set.Wherein, logical number is meant that operator distributes to user's one number, also is the number that the user outwards announces.After being provided with logical number and physical number for the user, when the user did caller, logical number was the calling number that the callee shows; When the user when called, be the number that the calling party dials; It simultaneously also is the number that the identification user also charges between operator or operator.If do not want to use number to change to existing user, this logical number can use number consistent with existing user, promptly when user applies behind the physical number, make logical number with existing numbers of user; Also can distribute new logical number for it according to new coding rule.As first number segment is that 123 number is a logical number.Like this, judging whether the user is when having applied for physical number, and system can judge according to the first number segment of called number.
User's physical number (be routing number: be meant that LRN) operator distributes to user's routing number, outwards do not announce, be the intercom number of network by this number.Certain port or subscribers feeder in the corresponding fixed switch of this number, described user's physical number information stores is on fixed switch or the database that links to each other with switch.The local network switching equipment can be according to the physical port at this number addressing user place.When the local network switching equipment detects certain port or subscribers feeder calling is arranged, can determine whether this port or subscribers feeder are provided with physical number according to the physical number information of hardware address retrieve stored on fixed switch of this calling.For example according to the coding rule of the corresponding physical number of hardware address, whether the hardware address corresponding physical number of judging this calling in the physical number information on fixed switch, as, judge that then this user is provided with physical number.When if this physical number is exactly hardware address, also can directly retrieves physical number information and judge according to this hardware address.A lot of according to switch ports themselves or subscribers feeder for the mode that the user is provided with physical number.Such as, the numbering of physical number can adopt the mode of " office's prefix+internal number ", when the calling subscriber breathes out, switch detects on its a certain port or the subscribers feeder calling, accept described calling, determine this port or subscribers feeder corresponding physical number, send with insertion office prefix method before internal number.During user's incoming call, the called number that switch is received is " office's prefix+internal number ", and whether the main dialing user score of the game is analysed current prefix is the local exchange prefix, if, then delete prefix, continue according to internal number; If not, then be routed to called subscriber end office (EO) with this innings prefix, continue according to internal number.This innings prefix can be numbered according to office's level, is toll switch, tandem exchange, end office (EO) successively as the prefix numbering.Because many business in the intelligent network,, all be to carry out routing, so this physical number also can be numbered with " route prefix prefix+internal number " form by the route prefix as 200,201 etc.At this moment, during user's incoming call, the called number that switch is received is " prefix prefix+internal number ", and the main dialing user score of the game is analysed the prefix prefix, determines corresponding trunk line, and then carries out corresponding routing and call proceeding.
Core concept of the present invention is: a kind of call connection method is provided, for the user is provided with logical number and physical number, set up logical number and physical number mapping table, when the calling user dials called number, when making a call, described connecting method comprises the steps:
When A, calling subscriber end office (EO) detect this calling subscriber's corresponding port or telephone wire calling is arranged, accept described call request,
B, judging whether described called subscriber is provided with physical number, in this way, is that logical number is searched described mapping table with described called number then, obtains called subscriber's physical number;
C, according to called subscriber's physical number route, the calling subscriber is continued to the called subscriber.
Search logical number and physical number mapping table,, judge that then the called subscriber is provided with physical number when this called number appears in the logical number item of mapping table; Perhaps judge by the logical number field.
Judge whether described calling subscriber is provided with physical number, in this way, search the logical number that mapping table determines that it is corresponding, this logical number is issued to called subscriber end office (EO) according to calling subscriber's physical number.
If calling subscriber and called subscriber all are not provided with physical number, handle by the industry normal flow.
In the telecommunication system that intelligent network is arranged, logical number information can be kept on the service control point (SCP) (service control point), and physical number information is kept on SCP and the switch, as shown in Figure 2.Must carry out number translation earlier when SCP and switch carry out Signalling exchange, logical number is translated into physical number.Can on SCP, set up user logic number and physical number mapping table, carry out number translation according to this mapping table.But for domestic consumer, known to just logical number, physical number is also invisible, operator also is to use logical number to safeguard in daily operation.This logical number, physical number and both corresponding relations also can all be kept on the switch, as are kept among the attaching position register HLR (Home Location Register) on the switch.
Thereby, be necessary original two aspects are segmented, segment out a service layer again at the SCP layer, as shown in Figure 2.
