Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of a method for automatically provisioning VoLTE service according to an embodiment of the present invention. The method shown in fig. 1 comprises 5 stages, in which:

stage one: and (5) pre-burying of a user.

For example, at time T1, the BOSS pre-embeds, in the HSS, the Access Point Name (APN) and Session Transfer Number (STN-SR) of N0 users.

And a second stage: a user initiates an IMS Packet Data Network (PDN) connection setup.

For example, at time T1, the N1 number of users send PDN connection requests (connection requests) to a Mobility Management Entity (MME), and the MME returns PDN connection responses (connection responses) to the users.

And a third stage: the user performs IMS registration for the first time.

For example, at time T2, the N2 number of users initiate IMS registration, query Call Session Control Function (I-CSCF) initiates a User Authentication Request (UAR) query service CSCF (S-CSCF) capability set to HSS, HSS queries no User subscription data, and returns a User Authentication Answer (UAA) carrying a failure cause value (e.g., 4999). The I-CSCF receives the UAA with 4999 and defines the user re-registration time with latency After it receives the UAA.

And a fourth stage: the user VoLTE service account opening is successful.

For example, at time T3, a number N3 of users request release of VoLTE service. And the HSS determines that the user does not sign the VoLTE data, and sends a notification (Notify) message to the BOSS, and the BOSS receives the Notify message and signs the VoLTE data for the user.

And a fifth stage: the user initiates the IMS registration again, and the IMS registration is successful.

For example, at time T4, the number N4 of users again initiates IMS registration and successfully registers with the IMS network.

In the automatic provisioning process shown in fig. 1, the BOSS performs user pre-embedding in stage one according to the method for automatically provisioning the VoLTE service described in fig. 2. As shown in fig. 2, the method includes:

s210, determining a target pre-burying number and a target pre-burying time, wherein the target pre-burying number is related to the interface capability of an interface between a BOSS (business operation support system) and a network element in an IP Multimedia Subsystem (IMS) and the message processing capability of the network element in the IMS.

S220, at the target pre-burying moment, adding the APN and the STN-SR of the target pre-buried user of the target pre-buried frequent visitor to a home server (HSS).

Generally, in stage one (user pre-buried stage) in fig. 1, the number of pre-buried users N0 is mainly constrained by the interface capability of the interface between the BOSS and the HSS. In the method shown in fig. 2, the number of the pre-buried instructions of each pre-buried user is 2, and then N0 needs to satisfy the following conditions: 2 × N0+ HSS background traffic (daily traffic volume) < interface capability of the interface between BOSS and HSS. In phase three (the user performs IMS registration for the first time), normally, the user should initiate an IMS registration request immediately after the IMS PDN connection is established. Assuming that the number of users initiating the first IMS registration is N2, N2 should satisfy the following condition: n2+ normal registration traffic < registration message handling capability of IMS network (including pcsccf network elements, ICSCF network elements, and HSS network elements). In phase four (user VoLTE service account opening success), the number N3 of users whose account opening succeeds in this phase needs to satisfy the following condition: n3 is the number of instructions for each network element (HSS/AS/ENS) + the interface capability of the interface between each network element (HSS/AS/ENS) and each network element (HSS/AS/ENS) for background traffic < BOSS. In stage five (the user initiates the IMS registration again), the behavior after the user opens an account is influenced by the BOSS opening mode, the user behavior, and the terminal device. For example, if it is specified that the user needs to initiate IMS registration again After Retry After the time duration, but the BOSS performs VoLTE account opening by deleting all user data (including 2/3/4G data) and then adding all user data in a way of opening VoLTE function for new user network access, which is affected by the terminal devices and user behaviors, some terminal devices may automatically attach to 4G and register the IMS network, and other terminal devices may use VoLTE service After the user is turned on or off again. Therefore, N4 needs to satisfy the following condition: n4+ normal park traffic < registration message handling capability of IMS network (including pcsccf network element, ICSCF network element, SCSCF network element, HSS or AS).

In summary, it can be known from the analysis that the interface capability of the interface between the BOSS and each network element mainly affects the first stage and the fourth stage, i.e., 2 × N0+ N3 × number of instructions of each network element (HSS/AS/ENS) + background traffic of each network element (HSS/AS/ENS) < interface capability of the interface between the BOSS and each network element. Meanwhile, the statistical value of the current net between 0 and 1 can be obtained according to the current net statistics, wherein N3 is A N1. The relationship between N1 and N0 is influenced by the terminal device and the user behavior, part of the terminal devices re-initiate the IMS PDN connection establishment when the user initiates Attach, TAU from 2G to 4G, or returns to 4G after the completion of the call drop of the calling and called parties, and part of the terminal devices regularly initiate (for example, once in 1 minute) the IMS PDN connection establishment. Assuming that the number of users initiating establishment of an IMS PDN connection is N1, the target embedded time is T0, the time when the user initiates establishment of an IMD PDN connection is T1, Δ T1 ═ T1-T0, and the relationship between N1 and N0 is a function that varies with T0 and Δ T1, that is, N1 ═ f (T0, Δ T1) × N0. Therefore, the target pre-buried quantity and the interface capability between the BOSS and the network element in the IMS satisfy the following relationship: 2 × N0+ a × f (T0, Δ T1) N0 × the number of orders of network elements in IMS + background traffic of network elements in IMS < interface capability of the interface between said BOSS and network elements in IMS.

Further, the message processing capability of the network elements in the IMS mainly affects the stage three and the stage five, i.e., N2+ N4+ normal registration traffic < the registration message processing capability of the IMS network (including pcsccf network elements, ICSCF network elements, and HSS network elements). Assuming that the number of users who initiate an IMS registration request again is N4, the time when the user successfully registers the IMS is T4, the number of users who successfully open the account is N3, the time when the user opens the account is T3, Δ T4 is T4-T3, the relationship between N4 and N3 is a function varying with T4 and Δ T4, that is, N4 is f (T4, Δ T4) N3. the number of users who successfully open the account N3 and the number of users who initiate the first IMS registration and fail to register N2 satisfy the following relationship: n3 × B N2, where B is substantially 1 without BOSS backlog. Therefore, the target pre-buried quantity and the message processing capacity of the network element in the IMS satisfy the following relation: a f (T0, Δ T1) N0+ a B f (T0, Δ T1) f (T4, Δ T4) N0+ normal registration traffic < message handling capabilities of network elements in IMS.

Optionally, in some embodiments, the determining the target pre-burying time in S210 includes: determining a target pre-embedding time window and a target pre-embedding time interval, wherein the target pre-embedding time window is related to at least one of user conversion rate, BOSS interface capacity, engineering network scheduling generation time period and business support monitoring and emergency capacity, and the target pre-embedding time interval is related to trigger rate of pre-embedding users for triggering and opening VoLTE service; and determining target pre-burying time according to the target pre-burying time window and the target pre-burying time interval.

Generally, the conversion after VoLTE auto-activation is mainly triggered by TAU from 2G to 4G, and statistics is performed on TAU triggering rules from 2G to 4G in a whole network one week (from 0 point at 4/2016 to 0 point at 10/12/2016), as shown in fig. 3, it can be seen that TAU times per user hour between 8 and 19 points are maintained at a high level, and TAU times at other times are less, which results in slower pre-buried user conversion. Especially, the user pre-buried at night is easy to centrally trigger the conversion behavior after 8 o' clock earlier, and impact is formed on the BOSS interface and the IMS network.

Further, by analyzing the instruction number of the interface between the single HSS and BOSS, it can be seen that the background traffic between 8 o 'clock and 20 o' clock is high, and the background traffic of the BOSS at night is very small, which is about 12.5% of the peak value during the day, but the night conversion rate is low, and the surplus BOSS interface capability cannot be effectively utilized. The network regulation of the network engineering is concentrated at 0 point to 4 points, during which various operations may affect pre-burying, triggering and registration behaviors, and it can be known from a conversion rate (a ratio of the number of users who automatically open the VoLTE service to the total number of pre-buried users) graph shown in fig. 4 that 45% of total triggered users complete conversion within 30 minutes, 65% of total triggered users complete conversion within 1 hour, 85% of total triggered users complete conversion within 2 hours, and the convertible users basically complete conversion within 5-6 hours after pre-burying, so that it can be determined that the end time of a target pre-buried time window is 18 points. And further considering that the business support can monitor the BOSS interface more timely in the daytime and has stronger emergency guarantee capability for emergency situations such as congestion. Therefore, in order to ensure that the embedding safety is controllable, the target embedding time window is 8-18 points.

As can be seen from the relationship between the user trigger rate and Δ T1(T1-T0) shown in fig. 5, the user trigger rate is the highest peak within 30 minutes after pre-embedding is completed, and then the trigger rate is greatly reduced. The trigger rate decreases linearly and uniformly from two hours later, and after 5-6 hours the trigger rate approaches 0. The user triggering rate is rapidly decreased along with the pre-buried time difference, the rate is greatly reduced after 2 hours, the triggering is hardly carried out after 5 and 6 hours, and the triggerable user is basically completely triggered. Therefore, the target pre-embedding time interval can be determined to be 30 minutes, the conversion peak value superposition of pre-embedding users of different batches can be effectively avoided, meanwhile, the single pre-embedding amount can be reduced by the smaller pre-embedding time interval, timely monitoring is facilitated, the BOSS and IMS network emergency situations can be adjusted, and the problem influence range is reduced.

Optionally, in some embodiments, the method shown in fig. 2 further includes: and determining a target embedding rate, wherein the target embedding rate is related to the target embedding quantity and the embedding time interval. Correspondingly, in S220, adding the IMS APN and STN-SR of the pre-buried users of the target pre-buried number in the HSS at the target pre-buried time includes: and adding the IMS APNs and the STN-SR of the target embedded users in the target embedded quantity in the HSS at the target embedded speed at the target embedded moment.

For example, taking the HSS device as an example, hua is 200 HSS account opening interface capability theoretical values/s, noci HSS account opening interface capability theoretical values 100 HSS account opening interface capability theoretical values/s, and VoLTE subscriber HSS account opening commands 30 HSS account opening commands/user. Meanwhile, according to the current network statistics, the daily HSS background mean value flow accounts for 15% of the capacity of the account opening interface, and 50% of the HSS interface capacity is set as the background flow by considering the service peak and the safety margin at the end of the month. And (3) comprehensively considering the pre-burying time interval of 30 minutes and the user triggering rule, analyzing the ratio of the overlapping triggering quantity to the overlapping pre-burying quantity of the user in every 30 minutes from 8 to 23, wherein the peak value 0.95 of the ratio is the value of f (T0, delta T1). Therefore, the target pre-burying quantity can be determined, and the target pre-burying speed can be determined according to the target pre-burying quantity and the pre-burying time interval. For example, the upper limit of the embedding rate of the Huashi HSS is 3 users/second, the upper limit of the embedding rate of the Norxi HSS is 1.5 users/second, and similarly, the upper limit of the embedding rate limited by the AS network element is 5 users/second and the upper limit of the embedding rate limited by the ENS network element is 50 users/second. Assuming that 3 networks in the IMS network are HSS, 2 norwest HSS, 5 ases and 1 ENS for opening an account, the upper limit of the pre-embedding rate limited by the HSS is 15 users/second, the upper limit of the pre-embedding rate limited by the AS is 25 users/second, and the upper limit of the pre-embedding rate limited by the ENS is 50 users/second. It can be seen that the message processing capacity of the HSS interface is the bottleneck, and assuming that the pre-burying time is 5 minutes each time, the pre-burying amount in each batch does not exceed 900 users/hua is HSS and 450 users/norxi HSS.

Furthermore, the registered message processing capacity of network elements such as CSCF in hua is about 2500 pieces/module/second, each CSCF is configured with at least 2 processing modules, the processing capacity is at least 5000 pieces/module/piece, which is much higher than the capability of an account opening interface of equipment such as HSS, and meanwhile, the background traffic occupancy rate of the network elements such as CSCF does not exceed 10%, so the message processing capacity of the current network element is not limited.

In conclusion, it can be known from the analysis that if the service peak periods and the non-working time at the beginning of the month and the end of the month are avoided, the pre-burying amount of 5 minutes in each batch of the pre-burying time is not more than 900 users/Hua, namely HSS and 450 users/Noxi HSS, in combination with the message processing capability of each network element.

Optionally, in some embodiments, before S210, the method shown in fig. 2 further includes: and selecting a target embedded user from candidate embedded users, wherein the candidate embedded users are users which support the VoLTE service and open the VoLTE switch but do not open the VoLTE service. Therefore, the automatic opening rhythm can be effectively controlled and the conversion efficiency can be improved firstly through the determination of the target embedded user, the impact of uncontrollable behaviors such as batch upgrading of the terminal equipment after embedding on a BOSS interface and network capacity is avoided, the invalid card user can be effectively avoided, the load of core network equipment is reduced, and the user perception is improved.

When the candidate embedded user is determined, the method can be realized through steps of terminal sniffing, switch discrimination, account opening inquiry, target screening and the like. In the terminal sniffing step, whether the terminal device is a VoLTE-capable terminal device may be identified through a Type Allocation Code (TAC) of the first 8 bits of an International Mobile Equipment Identity (IMEI) of the terminal device. In the switch judging step, whether the terminal equipment turns on the VoLTE switch is judged through a 'Voice domain for E-UTRAN' cell in an Attach Request message or a Tracking Area Update (TAU) Request message of the terminal equipment. In the step of account opening inquiry, whether the user opens an account in VoLTE is judged through an IMS VoPS parameter carried by an Attach Accept (Accept) message or a TAU Accept message. In the target screening step, the numbers of the candidate pre-buried users are finally obtained according to the MSISDN number list of the users who open the VoLTE switch but do not open the VoLTE service and the secondary screening condition.

The secondary screening condition here may be provided by the market sector of the operator. The secondary screening condition may be, for example, a number blacklist, a user number that opens a service mutually exclusive to the VoLTE service, or the like.

After the pre-embedding of the user is realized by the method shown in fig. 2, the BOSS can be further monitored and analyzed for the full automatic opening process such as pre-embedded user triggering, conversion, successful registration rule and the like based on big data, the real-time monitoring of each network element index of the VoLTE is realized, the BOSS interface performance can be evaluated by monitoring the time difference delta T3 fluctuation condition between T2 and T3, and the potential problems of terminal equipment, networks and the like in the automatic opening process of the VoLTE service can be analyzed and mined by combining the difference value of each stage between N0 and N4 and the terminal brand. The data shown in table 1 can be obtained at the time of specific monitoring.
