At present, when a large-scale event is held in a certain area, due to the dense crowd, if everyone makes voice calls, it may cause congestion of wireless resources, resulting in failure to connect to the called party in the area. If the call fails and the call is continued, it will cause greater congestion of wireless resources. However, there is currently no better solution on the IMS core network side to carry out relevant emergency processing, which seriously affects the user's call perception.

DETAILED DESCRIPTION

In order to make those of ordinary skill in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples consistent with some aspects of the present application as detailed in the attached claims.

Currently, there are very few users who make voice calls through CS. Calls are mainly made through 4G or 5G voice. The main 4G and 5G solutions currently include Voice over New Radio (VoNR), and 5G NR does not support EPS Fallback for voice services and high-definition calls or Voice over Long-Term Evolution (Voice over Long-Term Evolution or Voice over LTE, VoLTE).

Among them, VoNR: the user end is turned on and resides in 5G, establishes a voice PDU session through 5GC, registers on the IMS network and initiates a voice call; when the 5G coverage conditions cannot meet the voice service requirements, the call is switched to Long Term Evolution (LTE) through the 5G to 4G PS HO process to maintain call continuity.

EPS Fallback: The user end is powered on and resides in 5G, establishes a voice PDU session through 5GC, registers with the IMS network and initiates a voice call; the 5G wireless network rejects the voice bearer establishment request, and initiates a 5G to 4G PS HO or redirection process to switch the call to LTE, and establishes a voice bearer on the EPC to complete the subsequent voice call connection, thereby falling back from 5G to VoLTE.

VoLTE: The user terminal is turned on and resides on 4G, establishes voice relay through EPC, registers on the IMS network and initiates a voice call.

The 4G or 5G voice network needs to support different access scenarios of 4G or 5G users. The following takes the IMS side called related business process, taking the user accessing through the 5G radio access network (5G Radio Access Network, 5G RAN) and VoNR calling as an example to illustrate the call process. As shown in Figure 1, it is a schematic diagram of the call process of VoNR through 5G RAN access, where the description of each step is as follows:

Step 1: The called party queries the Interrogating-Call Session Control Function (I-CSCF) to receive the initial session call request INVITE message.

Step 2-5: The I-CSCF obtains the S-CSCF address registered by the called user through the Dynamic Routing Algorithm (DRA). The DRA carries a location information request message (Location-Info-Request, LIR) and a location information response message (Location-Info-Answer, LIA). The Unified Data Management (Unified Data Management, UDM) or the Home Subscriber Server (Home Subscriber Server, HSS) response message carries the S-CSCF address providing services to the called user.

Step 6: The I-CSCF on the called side routes the message to the S-CSCF according to the S-CSCF address returned by the UDM or HSS, and triggers the VoLTE Application Server (VoLTE AS).

Step 7-13: After receiving the INVITE message, VoLTEAS determines that the user has IMS registration, and then starts the called domain selection process, sending a User Datagram Protocol (UDR) request to UDM or HSS through DRA, requesting UDM or HSS to return the called user access domain selection (T-ADS) message. UDM calls the Namf_MT_ProvideDomainSelectionInfo service of the Access and Mobility Management Function (AMF) to obtain the domain selection information of the user terminal in the 5G domain. AMF returns 5G domain selection information, including whether IMS PS voice sessions are supported, the latest timestamp, and the access type. UDM sends a Universal Data Access (UDA) response message to VoLTEAS through DRA, carrying the domain selection result, including whether the selected domain supports IMS voice and the access type. If the user is in 5G, the access type returned by UDM is still 5G.

Step 14: VoLTE AS continues the call establishment process and sends the INVITE message to the Proxy-Call Session Control Function (P-CSCF) through the S-CSCF.

Step 15: P-CSCF sends the INVITE message to the User Plane Function (UPF).

Step 16: If the user terminal is in the idle state, UPF notifies the Session Management Function (SMF) to initiate the user paging process. After the user terminal is paged, the Quality of Service Flow (QoS Flow) between the user terminal and UPF is restored through the Service Request process.

Step 17: UPF sends the INVITE message to the terminal.

Step 18: The terminal returns a 183 response message.

Step 19-34: After receiving the Session Initiation Protocol (SIP) 183 message, the P-CSCF triggers a resource reservation process to the Policy Control Function (PCF).

Step 35: Both parties carry out subsequent media negotiation procedures, including the Provisional Response ACKnowledgement (PRACK) of unreliable transmission and the connection status UPDATE procedure.

Step 36: The called party picks up the phone after the ringing, and the call is connected.

The above scheme has the following shortcomings:

1. As in step 15 above, when P-CSCF sends INVITE to the 5G core network UPF, it cannot predict the network status of the called 5GC core network and wireless base station.

2. When a large-scale event is held in a certain area, due to the large number of people, if everyone makes a voice call, it may cause congestion of wireless resources and make it impossible to connect to the called party in the area. If the call fails and the call is continued, it will cause greater congestion of wireless resources. However, there is currently no better solution on the IMS core network side to carry out relevant emergency processing.

3. In this case, it will not only cause user congestion and inability to connect voice calls, but will also affect the core network indicators to a certain extent, bring greater load to the network, and seriously affect user perception.

In summary, when wireless resources are congested, during a 4G or 5G call, the called party in the area cannot be connected, and the core network side cannot perform relevant emergency processing, which seriously affects the user perception.

In order to solve the above problems, the embodiments of the present application provide an information processing method, apparatus, device, medium and program product, which predicts the second call attempt number of the eNodeB in the next time period of the first preset time according to the first call attempt number of the eNodeB corresponding to the target user when registering the first number. When it is determined that the second call attempt number is greater than the maximum concurrent call number of the eNodeB, the called side is controlled to reduce the sending of call request messages. In this way, when the wireless resources of the eNodeB corresponding to the first number are insufficient, the paging of the eNodeB is reduced by reducing the sending of call request messages, thereby alleviating the wireless congestion of the base station and ensuring the timeliness of the paging of the base station. The solution of the embodiment of the present application is implemented on the IMS core network side, thus filling the technical gap of the linkage mechanism between the core network and the wireless during call congestion emergency guarantee, and reducing the sending of call request messages on the core network side. The paging will not be sent to the congested base station, which is better than the solution of directly limiting paging on the base station, further improving user satisfaction.

The information processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

FIG2 is a flow chart of an information processing method provided in an embodiment of the present application. The execution subject of the information processing method may be a PSBC device on the IMS core network side.

As shown in FIG. 2 , the information processing method provided in the embodiment of the present application may include steps 210 to 230 .

Step 210: Obtain the first call attempt number of the eNodeB within the first preset time.

The eNodeB is a base station corresponding to the target user when registering the first number. The target user here may be a user who registers the first number, and the first number may be a number to be registered, such as a telephone number.

The first preset time may be a preset time before the current time and before a large-scale event is to be held. For example, a city plans to hold a concert on May 5, 2024, at which time a large number of people will gather, which may cause congestion in the city's network. If the current time is May 3, 2024, the first preset time may be May 1, 2024 - May 2, 2024.

The first number of call attempts may be the number of calls made by the eNodeB within the first preset time. The first number of call attempts here includes the number of call attempts by the calling party and the number of video calls made by the called party within the first preset time, that is, the number of active calls and the number of passive calls made by the eNodeB within the first preset time.

In some embodiments of the present application, before step 210, the above method may further include:

When the target user registers the first number, obtaining access network information (P-Access-Network-Info, PANI) of the first number, wherein the PANI includes the area tracking code TAC of the target area where the target user is located and the first identity information of the eNodeB;

storing a correspondence between the first number and the eNodeB in the target area according to the TAC and the first identity information;

Step 210 may specifically include:

The first call attempt number of the eNodeB in the target area within the first preset time is obtained.

The PANI may be the relevant information of the first number when the target user registers the first number. Specifically, the PANI may include the Trace Area Code (TAC) of the target area where the target user is located and the first identity information of the eNodeB. The target area here may be the area where the target user is located. For example, if the target user is located in the D cell of the C county of the B city of the A province, then the target area here is the D cell of the C county of the B city of the A province. The first identity information may be the identity information of the eNodeB, for example, the identification number (ID) of the eNodeB.

In some embodiments of the present application, when a VoNR user registers, the user number related information is carried, which may specifically include the user's private identity (IM Private Identity, PVI), public identity (IM Public Identity, PUI), the target area where the user is located, the registered contact address when the user registered the first number, etc. These fields will be saved on the P-CSCF as a basis for paging the called party during subsequent user calls. The registration message also includes a PANI field, which carries the TAC and eNodeB ID of the target area where the user is located.

In an example, the target user registers a first number, and the PANI field corresponding to the first number is: 3GPP-E-UTRAM-TDD; utran-cell-id-3gpp = "4600026001F3361C9", where 460 is the mobile country code (MCC), 00 is the mobile network code (MNC), 26001 is the TAC, and F3361C9 is the eNodeB ID. Here, "4600026001F3361C9" can represent the area where the target user is located, and there will be no conflicts or duplications in the planning.

It should be noted that in the prior art, after the user registers the first number, the user's PANI field will not be recorded on the PSBC. However, in the embodiment of the present application, the PSBC needs to save the PANI field of each user after the user successfully registers the first number, in preparation for subsequent called paging optimization innovation.

With the current existing technology, in order to meet the needs of emergency special services and paid special services zoned access, all PSBCs in the existing network are configured with the correspondence between PANI and the region, that is, all 5G RANs in the service area have data records on the PSBC network element.

Based on the above description, after the user registers the first number in the IMS network, it is possible to clearly determine which area each user is registered in. In other words, it is possible to locate all users registered in a certain area through a certain area.

In this way, when a large-scale event is held in a wireless area and the number of people is too dense, there is a risk of insufficient wireless resources. The core network IMS coordination is needed to avoid and solve the problem of insufficient wireless resources, but the core network equipment load is still very low at this time.

The current regional congestion is generally caused by congestion in the coverage area of some base stations. The PANI field can be used to obtain the identity information of the base station, and there is a corresponding relationship between the cell base station and the area. In this way, the correspondence between the first number and the eNodeB in the target area can be stored according to the TAC and the first identity information in the PANI field, and then the first number of trial calls of the eNodeB in the target area within the first preset time can be obtained, and then the network in the target area can be adjusted according to the above correspondence and the first number of trial calls.

In an embodiment of the present application, when the target user registers the first number, the PANI of the first number is obtained, and then the correspondence between the first number and the eNodeB in the target area is stored according to the TAC of the target area where the target user is located and the first identity information of the eNodeB included in the PANI, so as to realize the correspondence between the PANI and the base stations and congested areas in the target area. Then, the first number of call attempts of the eNodeB in the target area within the first preset time is obtained, so that the eNodeB network in the target area can be adjusted according to the first number of call attempts, so as to realize the dynamic adjustment of the area.

Step 220: predict the number of second call attempts of the eNodeB in a time period next to the first preset time according to the number of first call attempts.

Among them, the next time period of the first preset time may be after the first preset time, and may be a time period for holding large-scale events. Continuing the above example, taking the first preset time as May 1, 2024 to May 2, 2024 as an example, the next time period of the first preset time may be May 5, 2024.

The second number of call attempts may be the number of call attempts by the eNodeB within the next time period of the first preset time. The second number of call attempts here includes the number of call attempts by the calling party and the number of video calls by the called party within the next time period of the first preset time, that is, the number of active calls and the number of passive calls by the eNodeB within the next time period of the second preset time.

In some embodiments of the present application, in order to improve the prediction accuracy and prediction efficiency of the second call attempt number, step 220 may specifically include:

According to the first call attempt number, a call attempt number prediction model is used to predict the second call attempt number of the eNodeB in a time period next to the first preset time.

Among them, the call number prediction model can be a model pre-trained based on multiple groups of training samples for predicting the second number of trial calls of the eNodeB in the next time period of the first preset time. Each group of training samples here may include the number of trial calls of the eNodeB in the third preset time period and the number of trial calls of the eNodeB in the next time period of the third preset time period.

The third preset time period here may be a time period before the first preset time period, and the next time period of the third preset time period may also be a time period before the first preset time period. The next time period of the third preset time period here is preferably also a time period where large-scale events have been held, and the third preset time period may be a time period before a large-scale event is held.

Continuing to refer to the above example, taking the first preset time as May 1, 2024 - May 2, 2024 as an example, if a city held a large-scale event on October 8, 2022, the next time period of the third preset time here can be October 8, 2022, and the third preset time can be October 1, 2022.

The above-mentioned call frequency prediction model can be, but is not limited to, a neural network model, a support vector machine model, and a decision tree model based on deep learning. Specifically, in the embodiment of the present application, the call frequency prediction model can be a long short-term memory network (Long Short-Term Memory, LSTM) model. The specific training method of the LSTM model is consistent with the training method of the LSTM model in the prior art, which will not be repeated here.

Step 230: When it is determined that the second call attempt number is greater than the maximum concurrent call number of the eNodeB, control the called side to send less call request messages.

Among them, the maximum number of concurrent calls can be the maximum number of calls allowed by the eNodeB. The maximum number of concurrent calls here includes the number of call attempts and the number of video calls allowed by the eNodeB for the calling party, that is, the maximum number of concurrent calls is the number of active calls and the number of passive calls allowed by the eNodeB.

In some embodiments of the present application, the maximum number of concurrent calls of the eNodeB can be set in advance, and then after the second trial call number is predicted, it is determined whether it is necessary to execute a paging optimization strategy. Specifically, it can be determined whether the second trial call number is greater than the maximum number of concurrent calls of the eNodeB. If it is greater, the paging optimization strategy is executed. If not, normal paging is performed.

In some embodiments of the present application, since the call initiated by the calling side is a spontaneous behavior of the user and cannot be limited, when the paging optimization strategy is adopted, it can be executed on the called side. Specifically, the called side can control the sending of the call request message. In this way, if the called side does not send the call request message, the user will not be paged, and unnecessary resources will be occupied.

In some embodiments of the present application, when it is determined that the second call attempt number is greater than the maximum concurrent call number of the eNodeB, a paging optimization strategy can be executed, specifically controlling the called side to reduce the number of call request messages sent, thereby reducing the congestion of the wireless resources of the eNodeB.

In some embodiments of the present application, after step 220, the above method may further include:

When it is determined that the second call attempt number is less than or equal to the maximum concurrent call number, the called side is controlled to send all call request messages.

In some embodiments of the present application, when it is determined that the second call attempt number is less than or equal to the maximum concurrent call number, the paging optimization strategy may not be executed and a normal call may be performed, that is, the called side may be controlled to send all paging request messages normally.

In an embodiment of the present application, when it is determined that the second call attempt number is less than or equal to the maximum concurrent call number, the called side is controlled to send all call request messages. In this way, when the wireless network of the eNodeB is not congested, all call request messages can be sent normally to ensure normal calls of all call request messages.

In some embodiments of the present application, in order to further improve the accuracy of reducing the number of call request messages sent by the called side, step 230 may specifically include:

Determine the paging ratio based on the maximum number of concurrent calls and the second trial call number;

Control the called party to send fewer call request messages according to the paging ratio.

The paging ratio may be a ratio of the call request messages that the called side is controlled to reduce, which is determined based on the maximum concurrent call number and the second call attempt number.

In some embodiments of the present application, the paging ratio P may be determined according to the following formula (1) based on the maximum number of concurrent calls and the second number of call attempts:

Wherein, M is the maximum number of concurrent calls, and _Xn+1 is the second trial call number.

In some embodiments of the present application, the PSBC may control the called side to send a call request message according to the P ratio, and specifically may perform down-ratio paging according to the P ratio.

In an embodiment of the present application, the paging ratio is determined based on the maximum number of concurrent calls and the second number of trial calls, and then the called side is controlled to reduce the sending of call request messages according to the paging ratio. In this way, there is no need to not send all call request messages, but the sending of call request messages can be reduced according to a certain ratio. This avoids the situation where all call request messages are not sent and affects the user's calling experience, and at the same time improves the accuracy of the called side in reducing the sending of call request messages.

In some embodiments of the present application, in order to more clearly understand the solutions of the embodiments of the present application, the specific solutions of the embodiments of the present application are described in detail below. As shown in Figure 3, the information processing method may include steps 31 to 38.

Step 31: Collect the PANI of the target user when registering the first number.

In step 31, based on the collected PANI, the base station information (ie, eNodeB) corresponding to the first number and the target area where the target user is located can be obtained.

Step 32: According to the eNodeB dimension, the number of attempted calls between the calling party and the called party of the eNodeB is counted.

In step 32, statistics of the calling and called party call attempts of the eNodeB may be performed in advance according to the eNodeB dimension.

Step 33: Store the correspondence between the first number and the eNodeB in the target area according to the first identity information of the TAC and the eNodeB in the PANI.

Step 34: Obtain the first call attempt number of the eNodeB in the target area within the first preset time.

Step 35: predict the number of second call attempts of the eNodeB in a time period next to the first preset time according to the number of first call attempts.

Steps 33 to 35 have been described in detail in the above embodiment and will not be described again here.

Step 36: Determine whether the second call attempt number is greater than the maximum concurrent call number of the eNodeB. If so, execute step 37; if not, execute step 38.

Step 37: Determine the paging ratio, and perform paging on the eNodeB at a reduced ratio.

In step 37, the paging ratio may be calculated according to the maximum number of concurrent calls and the second number of call attempts in accordance with the above formula (1), and then the called side may be controlled to send less call request messages according to the paging ratio.

Step 38: Full scale paging.

In step 38, the called side may be controlled to send all call request messages.

The solution of the embodiment of the present application makes up for the problem that users cannot connect normally and the connection delay is large in the case of congestion caused by insufficient wireless resources. It can reduce wireless congestion and ensure the timeliness of paging. It fills the technical gap of the linkage mechanism between the core network and the wireless when calls are congested, and can further improve user satisfaction.

When the process of FIG. 1 is performed using the solution implemented in the present application, the flow chart is shown in FIG. 4 , and the steps of the flow chart are described as follows:

Steps 1-14 are consistent with steps 1-14 in FIG. 1 and are not described again here.

Step 15: Determine whether to send the INVITE message to UPF.

In step 15, after the called side receives the INVITE message, a paging policy decision is made to determine whether to send the INVITE message to the UPF. Specifically, for a congested eNodeB (i.e., the second trial call number of the base station is greater than the maximum concurrent call number of the base station, then the wireless of the base station is congested), paging is performed in proportion, and for a non-congested eNodeB (i.e., the second trial call number of the base station is not greater than the maximum concurrent call number of the base station, then the wireless of the base station is not congested), full paging is implemented.

Step 16: The 5GC or EPC core network initiates paging to the user who received the INVITE message and connects the called party.

It should be noted that the information processing method provided in the embodiments of the present application may be executed by an information processing device, or a control module in the information processing device for executing the information processing method.

Based on the same inventive concept as the above-mentioned information processing method, the present application further provides an information processing device. The information processing device provided in the embodiment of the present application is described in detail below in conjunction with FIG.

Fig. 5 is a schematic diagram showing the structure of an information processing device according to an exemplary embodiment. The information processing device can be applied to a PSBC device at the IMS core network side.

As shown in FIG5 , the information processing device 500 may include:

A first acquisition module 510 is used to acquire a first number of call attempts of an evolved base station eNodeB within a first preset time, wherein the eNodeB is a base station corresponding to when the target user registers the first number;

A prediction module 520, configured to predict, based on the first call attempt number, the second call attempt number of the eNodeB in a time period next to the first preset time;

The first control module 530 is configured to control the called side to send less call request messages if it is determined that the second call attempt number is greater than the maximum concurrent call number of the eNodeB.

By predicting the number of second call attempts of the eNodeB in the next time period of the first preset time based on the number of first call attempts of the eNodeB corresponding to the first number when the target user registers the first number, and when it is determined that the number of second call attempts is greater than the maximum number of concurrent calls of the eNodeB, the called side is controlled to reduce the sending of call request messages.
