A computer device 120 is connected to at least one terminal i 111 and terminal ii 112 to implement a communication service between the terminal i 111 and the terminal ii 112.
As shown in fig. 2, in an embodiment, a method for network slice management is provided, and this embodiment is mainly illustrated by applying the method to the server 120 in fig. 1. The method specifically comprises the following steps:
step S202, receiving a call request, wherein the call request comprises a target code number, and the target code number is a privacy number bound with a called number;
step S204, if the target code number is in a state of being migrated from the first network slice to the second network slice, redirecting the call request from the first network slice to the second network slice;
step S206, forwarding the call request to the called number through the second network slice.
In an embodiment of the present invention, a first terminal 111 and a second terminal 112 need to perform communication, such as telephone communication or short message communication, where one end is a calling party and the other end is a called party, in order to protect privacy of the called party, in one case, an intermediate number, also called a privacy number, is allocated to the called party without informing the calling party of a called party communication number, the intermediate number is bound with the called number, the intermediate number is called by the calling party, and then the intermediate number is switched to the calling number, so that communication between the calling party and the called party is achieved under the condition of protecting privacy of the called party. In the communication process, the terminal one 111 or the terminal two 112 directly calls the target code number, the server 120 receives a call request for the target code number, and the call request may be a call request, or may be a short message or multimedia message sending request, which is not specifically limited herein. In a period of time or after two terminal communication end, can retrieve the high-efficient utilization of code number to middle privacy number.
In one embodiment of the present invention, the target code number is assigned at the server in the NFV architecture, and the server in the NFV architecture assigns the code number to the server 120 in the present invention, that is, the privacy number technology is combined with the network function virtualization. The server 120 can decouple software and hardware and abstract functions, so that the functions of network equipment do not depend on special hardware any more, resources can be fully and flexibly shared, rapid development and deployment of new services are realized, and automatic deployment, elastic expansion, fault isolation, self-healing and the like are carried out based on actual service requirements; and according to the actual service carrying capacity, hardware resources and software resources are distributed and deployed to form mutually independent network slices, and the network slices have corresponding network functions such as a conversation function and a short message service function. In one case, as the traffic volume increases or decreases, different network slices need to be merged or newly added, and the code number needs to be transferred between different network slices. When the code number is transferred, the code number needs to be registered in a target slice so that the network slice can process a call request aiming at the code number, the transfer of the code number among different network slices needs time, the code number cannot be used in an original slice in the transfer process, the code number is not registered in the target slice, when the target code number is judged to be in a state of being transferred from a first network slice to a second network slice, in order to enable the code number to be continuously used, the call request is redirected to the second network slice from the first network slice, a routing signaling of the call request can be directed to the target slice, at the moment, a speech path of the call request is processed by computing resources and network resources of the target slice, the code number can also be used when the code number is transferred among the network slices, and the code number utilization efficiency is improved.
In one embodiment of the invention, the call request is forwarded to the called number through the second network slice. A code number is registered in a network slice, when a call request related to the code number is accessed, the network slice where the code number is registered processes the call request, for the subsequent processing steps, a called number bound with the code number can be inquired by the network slice, the network slice receives returned called number information, then sends a call to the called number, and after the network slice is communicated with a called party, the network slice overlaps the telephone channel of the called party and a calling party, so that the communication between the called party and the calling party is realized. When the called number is bound with the code number, the calling party displays the called number as the code number to protect the privacy of the called party; the calling number can also be bound with the code number, and at the moment, the called party displays that the incoming number is also the code number, so that the privacy of both parties is protected.
In an embodiment of the present invention, after redirecting the call request from the first network slice to the second network slice, the second network slice processes the voice channel logic of the call request, and then directly communicates with the called number according to the binding relationship between the number and the called number, the specific binding relationship between the number and the called number may not be managed in the slice, and may be managed by a separate function module, and different network slices may all query the called number bound to the number in the internal part thereof, and the function module can return the called number information to the network slice after receiving the query request. The code number in migration can continue to be registered in the target slice at this time. For the second network slice, it may be any network slice that has the same network function and unsaturated traffic carrying capacity.
In the embodiment of the invention, for the calling of the code number which is migrated between the network slices, the calling session is redirected, the calling is accessed into the target slice, the calling session function is specifically realized by the target slice, the usability of the code number in the migration is realized, the utilization rate of the code number is not reduced, the calling is not interrupted due to the migration of the code number, no perception is generated in the using process of a user, the utilization rate of the code number is high, and the user experience is good.
As shown in fig. 3, in an embodiment of the present invention, the specific steps of redirecting the call request from the first network slice to the second network slice are:
s302, acquiring IP addresses of the first network slice and the second network slice;
s304, changing a target IP address of calling data from a first network slice IP address to a second network slice IP address, wherein the calling data is used for calling the target code number after receiving the calling request;
s306, the call data is sent to the second network slice.
In one embodiment of the present invention, the incoming call request is transmitted to the network slice with the registered code number through the IP address of the network slice, and when the code number is in the migration state, the server 120 obtains the IP address of the first network slice and the slice address of the target network, and changes the target IP address of the call data from the IP address of the first network slice to the IP address of the second network slice, so that the call data is processed by the second network slice. The call data is data for calling a target code number after the call request is accepted. And transmitting the call data to the second network slice according to the IP address of the second network slice.
In an embodiment of the present invention, the state migrated from the first network slice to the second network slice specifically includes:
a state in which the code number of the first network slice is re-registered in a second network slice.
In the embodiment of the invention, the network slices are relatively independent virtual functions, the code numbers can be migrated among different network slices, and the code numbers can be migrated only when being migrated to realize the same functions in the second network slice. And the code number has a binding relationship with the called number in the network slice, and the code number is registered in the network slice, so that the incoming call channel aiming at the code number can be used in the registered network slice. In one aspect of the present invention, when a code number migrates between slices, the code number to be migrated is re-registered in a target slice, and thus a state in which the code number migrates from a first network slice to a second network slice specifically refers to a state in which the code number of the first network slice is re-registered in the second network slice.
Referring to fig. 4, in an embodiment of the present invention, the steps after redirecting the transmission target of the call request from the first network slice to the second network slice are:
s402, updating the state information of the successfully migrated code number;
s404, discarding the registration information of the migrated target code number in the first network slice.
In an embodiment of the present invention, after the code number is registered in the second network slice, the code number is successfully migrated, and at this time, the call request for the code number can be directly routed to the second network slice registered by the code number for communication without passing through the first network slice or redirecting the routing signaling of the call request. Meanwhile, the registration information of the code number in the first network slice is abandoned, and the migration of the code number among different network slices is realized.
Referring to fig. 5, in an embodiment of the present invention, the steps before the call request is accepted are:
s502, acquiring network slice management data, wherein the network slice management data is used for deploying computing resources and network resources of a network slice;
s504, acquiring code number management data, wherein the code number management data describes management information for controlling the migration of the code number;
s506, migrating the code number from the first network slice to the second network slice according to the code number management data and the slice management data.
In an embodiment of the present invention, before receiving a call request, a network slice needs to be managed and arranged according to a current service carrying capacity to adapt to the current service carrying capacity, and calculation and network resources are reasonably utilized. For example, when the service carrying capacity is too large, the number of current network slices is not enough to support service processing, and hardware resources and software resources need to be arranged to generate new network slices to process more services. Similarly, when the service carrying capacity is reduced, the resource utilization rate of the current network slice is low, and the network slices with small service carrying capacity need to be merged, so that the resource recovery is performed, and the resource utilization rate is improved.
In an embodiment of the present invention, network slice management data is obtained, and the network slice management data is used to deploy computing resources, network resources, and storage resources of the network slice, so that the computing resources, the network resources, and the storage resources of the portion form a network slice with a set network function. Specifically, a part of hardware resources and software resources are arranged according to network functions and are deployed into a network slice instance according to the network functions, and the network slice instance can realize corresponding network functions.
In an embodiment of the present invention, code number management data is obtained, where the code number management data is management information describing control of code number migration, that is, a code number to be migrated and a called number bound to the code number to be migrated are specified, and a second network slice to be migrated of the code number to be migrated is also obtained. The code number management information may also include information describing the state of the code number to facilitate understanding of the state in which the code number is located. The code number management data may also be used to assign an intermediate code number to the called number, causing an association to be made between the called number and the code number.
In an embodiment of the present invention, after the code number management data and the network slice management data are obtained, the server 120 migrates the corresponding code number to the second network slice according to the indication of the obtained code number management data and the network slice management data, so as to implement reasonable allocation and deployment of internal computing resources and network resources.
In one embodiment of the present invention, the second network slice is a network slice whose carrying capacity is not saturated. As a situation of the present invention, when there is a large amount of traffic and a large amount of bearer, the first network slice may be a network slice whose bearer is saturated or is nearly saturated, a new network slice needs to share a part of traffic bearer, specifically, a new code number needs to be registered in the new network slice, or a part of code numbers in the first network slice may be migrated to the new network slice, and the new network slice implements a network function. The new network slice may be a network slice generated when traffic volume increases, such as a network slice generated after acquiring the network slice management data and before code number migration; or an existing but not saturated bearing capacity network slice; at this time, the several new network slices may be target slices for code number migration.
In an embodiment of the present invention, the first network slice is a network slice that needs to be resource-recycled after all code number migration is completed according to network slice management data. As a case of the present invention, when the traffic volume is small, there are multiple network slices processing the same type of service, and there are network slices with small carrying capacity, the resource utilization rate is low, and resource needs to be reconfigured as well, that is, multiple network slices processing the same type of service are merged, and when merging, data inside the network slices needs to be merged or migrated, that is, code numbers in different network slices are migrated to network slices with unsaturated carrying capacity, and the network slices with unsaturated carrying capacity are target slices. The first network slice is a network slice which needs resource recovery according to the network slice management data, and the time for resource recovery is that after all code numbers in the first network slice are migrated to the target slice, the code numbers in the first network slice can be migrated to the same second network slice, or can be migrated to different second network slices.
In the embodiment of the present invention, in one case, the network slice management data may manage to generate only a new second network slice when traffic increases, in one case, the network slice management data may manage to recover only the first network slice when traffic decreases, and in another case, when the slice is used for switching between different network functions, the second network slice may be a newly generated second network slice, and the first network slice may be a network slice that needs to be recovered.
As shown in fig. 6, for providing a specific example of a network slicing architecture for the present invention, the server 120 includes:
the NFV MANO (network function virtualization-management and virtualization orchestrator) is responsible for allocating basic hardware resources required by network slices, completing deployment of virtual network functions on virtualized basic hardware, and completing network connection between network function hardware, so as to implement dynamic deployment and deletion of network slices.
The VNFO (virtualized network function organizer) is responsible for unified configuration and management of cooperative work of network elements within and between network slices.
I-CSCF (interworking-Call Session Control Function, Interrogating Call Session Control Function).
The NFV MANO, VNFO, I-CSCF may each be connected to different network slices for managing network functions of the network slices.
Further included in the network slice is:
the P-CSCF (Proxy-Call Session Control Function) maintains registration and registration of code numbers to enable Call requests to be routed to network slices.
The MS (Media Server) is responsible for completing the functions of Media negotiation, encoding and decoding, playback, etc. during the call.
The SMS (Short Message Service) is responsible for completing the Short Message uplink and downlink processes in the call process.
NLM (number location management) manages and maintains the number state in the network slice.
And the AS (Application Server) is used for uniformly scheduling functions of the P-CSCF, the MS, the SMS and the NLM and is mainly responsible for incoming call and outgoing call control, butt joint with a service arrangement layer and sip signaling control and butt joint.
In an embodiment of the present invention, when the traffic volume increases, a new network slice is needed to carry the traffic, and the existing network slice calculates and allocates the code number to be migrated according to its own carrying capacity, that is, network slice management data and code number management data can be generated.
And according to the network slice management data, the NFV MANO deploys basic computing resources, storage resources and network resources to generate a newly deployed network slice.
According to the code number management data, the code numbers to be migrated and newly allocated from the existing network slices can be simultaneously registered in batches in the newly deployed network slices.
During registration, for the code number to be migrated, the VNFO controls the original slice P-CSCF to redirect the routing signaling to the newly deployed slice P-CSCF, i.e., the call request for the code number in migration is re-accessed to the newly deployed network slice P-CSCF, and the speech path is processed by the computing resources and network resources of the newly deployed network slice.
After the code number is successfully registered, updating the code number state to the NLM of the new network slice, and synchronously sending the code number state to the NFV MANO and the NLM of the existing network slice for synchronizing the consistency of the database states and updating the part of code number state data from the NLM of the existing network slice; the updating of the state of the registration success code number can be processed in parallel, and the calculation efficiency is improved.
And for the newly-incoming call and the short message service to be routed to a new network slice, the registration information of the first network slice is abandoned after being expired, and the user can not sense the whole process in the service migration process.
In an embodiment of the present invention, when traffic is reduced or a temporary scenario is eliminated, network slices need to be merged, and corresponding computing resources, storage resources, and network resources need to be recycled or reallocated, so that network slice management data and code number management data can also be generated.
And acquiring the network slices needing to be merged by the NFV MANO according to the network slice management data.
And managing data according to the code numbers, and performing batch registration on all the code numbers to be combined in the second network slice, namely performing a migration process.
In the process of registration migration, for an incoming call channel aiming at a code number to be migrated, the VNFO controls the P-CSCF of the first network slice to redirect a routing signaling to the P-CSCF of the second network slice, and the second network slice is a network slice with unsaturated service bearing capacity.
And after the code number is successfully registered, updating the code number states in the NLM and NFV MANO databases.
For the incoming call request, the new incoming call request is directly routed to the merged second network slice, and the code number registration information in the first network slice is abandoned after being naturally expired.
And initializing and recycling the network slice resource after observing that the call request speech path carried by the merged network slice returns to zero.
According to the embodiment of the invention, the network slice is elastically stretched according to different service bearing capacities, and meanwhile, when the code number in the network slice is migrated, the code number can be normally used in the migration process or the migration waiting process by redirecting the incoming call channel and processing the code number by the second network slice, so that the non-perception experience of a user is realized.
Referring to fig. 7, in an embodiment of the present invention, a network slice management method is provided, and this embodiment is mainly illustrated by applying the method to the server 120 in fig. 1. The method specifically comprises the following steps:
s702, acquiring network slice management data, wherein the network slice management data is used for deploying computing resources and network resources of a network slice;
s704, deploying and generating a second network slice according to the network slice management data;

s708, migrating the code number from a first network slice to a second network slice according to the code number management data; a call request for a code number in a migrated state, the call request handled by a second network slice.
In an embodiment of the present invention, the network slice needs to be managed and arranged according to the current service carrying capacity to adapt to the current service carrying capacity, and the calculation and network resources are reasonably utilized. For example, when the service carrying capacity is too large, the number of current network slices is not enough to support service processing, and hardware resources and software resources need to be arranged to generate new network slices to process more services. Similarly, when the service carrying capacity is reduced, the resource utilization rate of the current network slice is low, and the network slices with small service carrying capacity need to be merged, so that the resource recovery is performed, and the resource utilization rate is improved.
In an embodiment of the present invention, network slice management data is obtained, and the network slice management data is used to deploy computing resources, network resources, and storage resources of the network slice, so that the computing resources, the network resources, and the storage resources of the portion form a network slice with a set network function. Specifically, a part of hardware resources and software resources are arranged according to network functions and are deployed into a network slice instance according to the network functions, and the network slice instance can realize corresponding network functions.
In an embodiment of the present invention, code number management data is obtained, where the code number management data is management information describing control of code number migration, that is, a code number to be migrated is specified, and a second network slice to which the code number to be migrated is yet to be migrated is obtained. The code number management information may also include information describing the state of the code number to facilitate understanding of the state in which the code number is located. The code number management data may also be used to assign an intermediate code number to the called number, causing an association to be made between the called number and the code number.
In an embodiment of the present invention, after the code number management data and the network slice management data are obtained, the server 120 migrates the corresponding code number to the second network slice according to the indication of the obtained code number management data and the network slice management data, so as to implement reasonable allocation and deployment of internal computing resources and network resources.
In an embodiment of the present invention, the second network slice is a newly deployed generated network slice. As a situation of the present invention, when there is a large amount of traffic and a large amount of bearer, the first network slice may be a network slice whose bearer is saturated or is nearly saturated, a new network slice needs to share a part of traffic bearer, specifically, a new code number needs to be registered in the new network slice, or a part of code numbers in the first network slice may be migrated to the new network slice, and the new network slice implements a network function. The new network slice may be a network slice generated as traffic grows, such as a network slice generated after acquiring network slice management data and before code number migration.
According to the embodiment of the invention, the network slice is newly deployed according to the increase of the service bearing capacity, and meanwhile, the code number in the network slice is processed by the second network slice through the redirection of the incoming call channel when the code number is migrated, so that the code number can be normally used in the migration process or the migration waiting process, and the non-perception experience of a user is realized.
