Binding numbers will result in a large number of escape numbers in the number pool not being effectively utilized. Meanwhile, with the increase of the number hiding requirement, the number binding method in the prior art causes the capacity of a number pool for storing the escape number to be rapidly increased, and needs to occupy huge storage resources.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The number hiding device of the present embodiment, as shown in fig. 1, includes a number assigning device 111, a timing device 112, a counting device 113, a plurality of escape numbers 114, and a memory 115, where the memory 115 includes a free area 116, an occupied area 117, and a pre-release area 118. The memory 115 is used for storing a plurality of escape numbers 114. The number assigning means 111 is arranged for receiving the real number and for assigning an escape number 114 to said real number from the free area 116 and for transferring the escape number 114 to the occupied area 117.
The timing means 112 are arranged to detect the free time of the escape number 114 in the occupied area 117. The free time is the time when the escape number 114 in the occupied area 117 is not accessed and not reallocated, that is, the escape number 114 enters the occupied area 117, the timing device 112 starts to time the escape number, and once the escape number 114 is called or reallocated to another real number, the free time of the escape number 114 is cleared and recalculated, but the calculation of the free time of the other escape number 114 in the occupied area 117 is not affected. The number assigning means 111 is further configured to forward the escape number 114 with the free time exceeding the time threshold to the pre-release area 118. The time threshold may be set as required, or may be set dynamically according to the idle time statistics of the escape number 114 or according to the called condition of the escape number 114. When the idle time exceeds the time threshold, which indicates that the escape number 114 is allocated to a real number, the escape number 114 has a long time to be unused and is always in an idle state, and if the escape number is not released, the escape number cannot be fully utilized, which causes waste of escape number resources. Therefore, the escape number 114 is transferred to the pre-release area, and is waited for recycling and reuse.
The counting means 113 is arranged to count the number of escape numbers 114 in the free area 116. The number assigning means 111 is further arranged to transfer the escape numbers 114 from the pre-release area 118 to the free area 116 when the number is below the number threshold (this operation is the recycling of escape numbers). The number threshold may be set to some absolute value or may be set to a proportional value. For example, the number threshold is a ratio of the space remaining in the free area 116 (the number of escape numbers that can also be stored) to the total space of the free area 116, or a ratio of the space remaining in the free area 116 to the total number of escape numbers 114.
The aforementioned transferring of the escape number 114 in the occupied area 117 into the pre-release area 118 can be performed in real time, that is, whenever there is an escape number 114 with idle time exceeding the time threshold, the escape number 114 is immediately transferred into the pre-release area 118; a timed operation may also be adopted, for example, every time a preset time interval elapses, the escape number 114 whose idle time exceeds the time threshold is transferred to the pre-release area 118; for example, when the number of escape numbers 114 in the idle area 116 is lower than the number threshold, the counting device 113 takes this condition as an early warning signal, and the number assignment device 111 receives the early warning signal and transfers the escape numbers 114 with idle time exceeding the time threshold into the pre-release area 118. The aforementioned transferring of the escape number 114 in the occupied area 117 to the pre-release area 118 can be performed by transferring a plurality of escape numbers 114 at a time (e.g. in a timed mode, an interrupted mode); the escape numbers 114 in the occupied area 117 can also be transferred to the pre-release area 118 sequentially according to the order of the free time (exceeding the time threshold), for example, in a timing mode and an interruption mode, one or more escape numbers 114 with the longest free time are transferred to the pre-release area 118 each time, so that the flexibility of dynamic pre-release and recovery of escape numbers is improved, the called chance of the escape numbers 114 with the free time exceeding the time threshold is still reserved when the escape numbers 114 in the free area 116 are abundant, and the elasticity of the escape number pre-release and recovery operation is increased.
If there are not enough escape numbers 114 in the pre-release area 118 to reclaim to replenish the free area 116 when the number of escape numbers 114 in the free area 116 is below the number threshold, the number of escape numbers 114 in the free area 116 will gradually be less than 0 in further number allocation. At this time, the escape number 114 cannot be naturally allocated from the free area 116. Thus, as a preferred embodiment, if the number assigning means 111 receives the real number at this time, the number assigning means 111 assigns an escape number 114 to the real number from the occupied area 117. Preferably, the escape number 114 allocated for the real number from the occupied area 117 is the escape number with the longest idle time.
The present embodiment further provides a number hiding method, which uses the number hiding apparatus of the present embodiment, as shown in fig. 2, and the number hiding method includes the following steps:
s101, the number distribution device 111 receives a real number, distributes an escape number 114 to the real number from the idle area 116, and transfers the escape number 114 to the occupied area 117;
s102, the timing device 112 detects the idle time of the escape number 114 in the occupied area 117;
s103, the number distribution device 111 transfers the escape number 114 with the idle time exceeding the time threshold value into the pre-release area 118;
s104, counting the number of escape numbers in the idle area 116 by the counting device 113;
s105, when the number of escape numbers 114 in the free area 116 is lower than the number threshold, the number assigning apparatus 111 transfers the escape numbers 114 in the pre-release area 118 to the free area 116.
Specifically, in the initial state, all escape numbers 114 are stored in the free area 116, and the counting device 113 obtains the total number of escape numbers in the free area 116 in the initial state. When the number assigning means 111 receives the real number, an escape number 114 in the free area 116 is assigned to the real number to hide the real number by the escape number 114. The allocation method may be random or according to a specific method. The number assignment means 111 transfers the escape number 114 to the occupied area 117. The counting means 113 subtracts 1 from the number of escape numbers in the free area 116.
After the escape number 114 enters the occupied area, the timer 112 starts to count the idle time of the escape number 114. Once the escape number 114 is called, or reassigned to another real number, the idle time is cleared and recalculated. When the idle time exceeds the time threshold, the number assigning device 111 transfers the escape number 114 to the pre-release area 118, i.e. performs the pre-release operation of the escape number. The escape number 114 is not used and accessed too long when idle, and is a waste of resources if not released, and therefore, is placed in the pre-release area 118 to wait for reclamation. The pre-release operation may be performed in real time, i.e., whenever the idle time exceeds a time threshold, the escape number 114 is transferred to the pre-release area. It is also possible to perform timing, for example, every preset time interval, detect the presence or absence of escape numbers 114 whose idle time exceeds the time threshold, and if so, perform a pre-release operation. It is also possible to perform a pre-release operation when a preset condition occurs, for example: when the number of escape numbers 114 in the free area 116 is below a number threshold, a pre-release operation is performed. The pre-release operation is performed, the pre-release operation may be performed on the corresponding escape numbers 114 in the order of the idle time from long to short, or all escape numbers 114 whose idle time exceeds the time threshold may be pre-released at one time.
As the number assignment process proceeds in the number hiding operation, the number of escape numbers 114 in the free area 116 will decrease. When the number of escape numbers 114 in the free area 116 is lower than the number threshold, the number allocation apparatus 111 transfers the escape numbers 114 in the pre-release area 118 to the free area 116, that is, dynamically recycles the escape numbers 114 that are too long in idle time, and recycles the escape numbers 114 that are too long in idle time in the occupied area 117 for reuse.
If there are no escape numbers in the pre-release area 118 when the number of escape numbers 114 in the free area 116 is lower than the number threshold, it is naturally not possible to perform the operation of transferring the escape numbers 114 in the pre-release area 118 to the free area 116. If the number assigning means 111 receives the real number at this time, it continues to assign an escape number 114 to the real number from the free area 116.
According to the above operation, a case may occur where the number of escape numbers in the free area 116 is 0. At this time, the number assigning means 111 receives the real number, and assigns a selected escape number 114 from the occupied area 117 to the real number. Preferably, the selected escape number 114 is the escape number that occupies the longest idle time in the area 117.
The number hiding device and the number hiding method can greatly improve the dynamic utilization rate of the escape numbers in the number pool (memory) and greatly reduce the capacity of the number pool (memory), namely save the storage space required by storing the escape numbers.
Example 2
The present invention further provides a number hiding system, as shown in fig. 3, the number hiding system includes the number hiding device 11 of embodiment 1, and further includes a call forwarding module 12; the call forwarding module 12 is configured to, when the calling device calls the escape number, obtain the real number from the number hiding device 11, and establish a communication connection between the calling number of the calling device and the real number.
Preferably, the call transfer module 12 includes an IVR module 121, a middleware server 122; the IVR module 121 is configured to send the calling number, the escape number, and the call time to the middleware server 122, obtain a real number from the middleware server 122, and establish a communication connection between the calling number of the calling device and the real number; the middleware server 122 is configured to obtain the real number from the number hiding device 11.
Specifically, the call transfer module 12 mainly includes an IVR module 121, a middleware server 122, and the like. The IVR module 121 is configured to receive call information (including a calling number, an escape number, and call time) of a calling device, perform data interaction with the middleware server 122 through an HTTP (HyperText Transfer Protocol) Protocol-related interface, acquire a real number, and provide a call forwarding function. The middleware server 122 performs data interaction with the IVR module 121 through an HTTP protocol, and accesses the number hiding device 11 through JDBC (Java DataBase Connectivity); the middleware server 122 provides a load sharing function service through multiple servers, and supports concurrent interaction of large data volume. Based on the above structure, the customer dials the escape number and can transfer to the real number for communication.
The specific process is as follows: the calling device calls the escape number, the voice signaling gateway receives the request (i.e. the call information, including the calling number, the escape number and the call time), and sends the request to the corresponding IVR module 121; the IVR module 121 obtains the original called party (i.e. the escape number) after receiving the incoming call request; the IVR module transmits information such as the calling number, the original called party (i.e. the escape number), the incoming call time, etc. to the middleware server 122; the middleware server 122 requests the number hiding device 11 to query the real number corresponding to the original escape number; the number hiding means 11 returns the real number to the middleware server 122; after obtaining the real number, the IVR module 121 establishes a call and connects the real number (called device); the called signaling connection is successful; the calling number is communicated with the real number, and voice media are interacted; after the normal conversation is finished, the voice gateway generates a recording file; after the call is finished, the IVR module 121 pushes the acquired traffic data to the middleware server 122; the middleware server 122 writes the traffic data dotting record to the database.
The number hiding system can hide real numbers and has good identity confidentiality.
