Description
Technical Field
The present invention relates to the field of communications, and in particular, to a dynamic number allocation method and system.
Background
In the telecommunications industry, each mobile subscriber handset has a SIM card therein, to which one or more handset numbers are bound. The mobile phone number used in China is 11 digits, wherein each segment has different coding directions: first 3 bits-network identification number; 4-7 th-region code; 8-11 th bit-user number, the number 130 to 132 sections are the sections of communicating mobile phone numbers; the No. 133 section is a telecommunication mobile phone number section; china moves occupies the remaining 6 sub-segments, including segments 134-139. According to the principle of using the telecommunication number, the capacity of the telecommunication number is generally 50% of the theoretical capacity, namely, the utilization rate of the number resource is nearly saturated. According to the analysis of the existing 6 number segments of China Mobile, the practical upper limit of the mobile user number capacity should be about 3 hundred million; the upper limit of the communication is about 2 hundred million, and the upper limit of the telecommunication is about 1 hundred million, so that the number resource is more and more in shortage along with the development of telecommunication service.
In recent years, telecom operators have been developing prepayment services, and individual customers can directly purchase a SIM card with a number in various channels to use, for example, service brands such as china mobile China and dynamic terrain, and China Unicom Ruyi. For operators, the phone card of the prepaid service needs to perform binding account opening, card making, delivery, sale and other processes on the SIM card and the number in an accounting system, and the number resource needs to be occupied from account opening, wherein the whole period is one or two months, and the whole period is slow and may need half a year or even longer, so that the utilization rate of the number resource is seriously reduced, and the development of the operators is greatly restricted under the condition that the number resource is increasingly in short supply.
Therefore, how to fully improve the number utilization rate under the limited number resources as an operator to preempt market initiatives is a problem to be solved urgently.
Disclosure of Invention
The invention aims to solve the technical problem of providing a dynamic number allocation method and a dynamic number allocation system aiming at the defects of the prior art.

Further, in step S3, the specific implementation of the accounting system opening an account for the allocated dynamic number according to the account opening instruction is as follows: and after receiving the account opening instruction, the tent system sends the account opening instruction to an Online Charging System (OCS), a Home Location Register (HLR), a number portable service (NP) and a Service Access Control (SACP).
The beneficial effect of adopting the further scheme is that: the specific operation of opening an account for the dynamic number is given, that is, some network elements and peripheral systems send an account opening instruction to enable the network elements and the peripheral systems to open the specific function of the dynamic number, so that the dynamic number can be normally used.
Furthermore, the home location register HLR and the number portable service NP return account opening success information to the tent system according to the received account opening instruction, and the tent system sends the dynamic number to the mobile phone of the user in a short message mode.
The beneficial effect of adopting the further scheme is that: because the user does not know the card number of the user when the user does not use the card, the dynamic number is opened and then the specific number is sent to the user, so that the user can know the mobile phone number of the user at the first time.
Furthermore, the accounting system prestores IMSI which is pre-account opened in batch and bound with virtual numbers, and when the accounting system receives an account opening instruction, the virtual number corresponding to the IMSI is modified into an allocated dynamic number.
The beneficial effect of adopting the further scheme is that: by pre-account opening the IMSI in batches, the account opening time can be saved, and only the virtual number corresponding to the IMSI needs to be changed into a dynamic number.

Further, after receiving the account opening instruction, the billing system sends the account opening instruction to an online charging system OCS, a home location register HLR, a number portable service NP, and a service access control SACP.
The beneficial effect of adopting the further scheme is that: the specific operation of opening an account for the dynamic number is given, that is, some network elements and peripheral systems send an account opening instruction to enable the network elements and the peripheral systems to open the specific function of the dynamic number, so that the dynamic number can be normally used.
Furthermore, the home location register HLR and the number portable service NP return account opening success information to the tent system according to the received account opening instruction, and the tent system sends the dynamic number to the mobile phone of the user in a short message mode.
The beneficial effect of adopting the further scheme is that: because the user does not know the card number of the user when the user does not use the card, the dynamic number is opened and then the specific number is sent to the user, so that the user can know the mobile phone number of the user at the first time.

Step S3, the accounting system allocates dynamic number for IMSI according to the account opening command and opens account for the allocated dynamic number.
And after receiving the account opening instruction, the accounting system performs account opening processing, allocates a number for the IMSI and sends the account opening instruction to each network element and the peripheral system. In a specific embodiment, the billing System sends the account opening instruction to an OCS (online charging System), an HLR (Home Location Register), an NP (Number Portability Service), and an SACP (Service Access Control Point), respectively. The HLR and the NP return successful account opening information to the accounting system according to the received account opening instruction, the accounting system sends a welcome short message to inform a user of MSISDN (Mobile Subscriber ISDN/PSTN number), namely number information distributed by the user, and the dynamic number is sent to the Mobile phone of the user in a short message mode.
And step S4, the accounting system returns the account opening result to the signaling platform through the dynamic number system.
And after the tent system finishes processing, returning an account opening result to the dynamic number system, and returning the account opening result to the signaling platform by the dynamic number system. In a specific embodiment, the account opening result has at least two conditions, the account opening is successful or failed, and the final account opening result is sent to the signaling platform no matter the account opening is successful or failed.
And step S5, the signaling platform starts the user according to the account opening result. The starting up is put through, and a user can use the dynamic number to carry out conversation, so that two steps of network element opening and signaling platform putting through are met.
