Description
Technical Field
The present invention relates to the field of mobile core network technologies, and in particular, to a method, an apparatus, and a readable medium for querying a user status.
Background
The existing voice service can only be carried in a Circuit domain (CS), and a user must attach to a Mobile switching Center/visitor Location Register (MSC/VLR) of the CS domain, and a service platform (e.g., a false caller id detection platform) can query a Home Location Register/Home Subscriber Server (HLR/HSS) for a user status, location information, etc. (default is CS domain query), and query the CS domain MSC/VLR for a user status, location information, etc.
With popularization of Voice over Long Term Evolution (VoLTE) services and terminals, more and more users are attached to a Packet Switch domain (PS) to perform Voice call through VoLTE, and if a service platform further queries information such as user states and positions based on a CS domain MSC/VLR manner, returned information is not aligned or not checked at all, for example, if the terminal is jointly attached, that is, if the terminal is attached to both CS and PS domains, the returned user states are idle, which causes misjudgment of the service platform, and the call is considered as a false calling; if the terminal is attached to the PS domain, no information can be obtained because no MSC/VLR address exists. In addition, even if the user state information is acquired in the VoLTE state, since it is not possible to know whether VoLTE voice or VoLTE data is being performed based on the user state information, a false misjudgment situation of the caller id detection platform still occurs.
Therefore, how to acquire the user status information to accurately identify whether the VoLTE voice call or the VoLTE data transmission is performed is one of the technical problems that are considered first.

Detailed Description
The user state query method, the user state query device and the readable medium provided by the embodiment of the invention are used for acquiring the state information of the user so as to accurately identify whether VoLTE voice call or VoLTE data transmission is carried out.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
To facilitate understanding of the invention, the technical terms involved in the invention are as follows:
1. an IP Multimedia Subsystem (IMS) is an IP Multimedia Subsystem, which is a brand new Multimedia service format and can meet the requirements of the current terminal clients for more novelty and diversification of Multimedia services.
2. Access Point (Access Point Name, APN), which is a network Access technology, is a parameter that must be configured when a mobile phone accesses the internet, and determines which Access method the mobile phone accesses the network.
Currently, for false caller calls, in order to verify that a call from an external network enters the home network through a Gateway Mobile Switch Center (GMSC), the call is triggered to a false caller detection platform, as shown in fig. 1. After the detection platform extracts the calling number, according to the network to which the detection platform judges the detection platform belongs, the platform can initiate query to the HLR or HLR/HSS to which the user belongs through a standard interface and a protocol, for example, an ATI (Any Time interaction) message of a MAP protocol contains information (such as user state, position, domain and the like) needing to be queried. After the home HLR or HLR/HSS receives the query message, it initiates a query to a visited network element registered by the user, for example, PSI (provider Subscriber Info) information of MAP protocol includes information to be queried (e.g., user status, location, etc.). After receiving the query message from HLR or HLR/HSS, the visiting place network element returns a response message according to the requested content (such as user state, position and the like); and the HLR or the HLR/HSS is forwarded to the platform to complete the query process. The platform judges whether the calling user is a false calling according to the information of the user state, the position and the like.
The inventor finds that the voice service can be carried only in the CS domain before, the user must be attached in the CS domain, and the false calling detection platform inquires information such as user state and position from the MSC/VLR through the HLR/HSS. However, when a user attaches to VoLTE for a call or attaches to a CS domain and a PS domain in a combined manner, the user state information cannot be accurately obtained by using the existing method, and even if the user state information is obtained, it cannot be accurately identified whether the user is performing a VoLTE voice call. The method comprises the steps that when a service platform receives a user state request message aiming at a packet switching PS domain supporting VoLTE voice communication, a user state query request is sent to user data equipment; after receiving the user state query request, the user data equipment sends the user state query request to a PS domain network element registered by the user, the PS domain network element queries user state information of the user, and in order to enable a service platform to accurately determine whether the user is carrying out VoLTE voice call, the PS domain network element carries VoLTE voice state information in the user state information sent to the user data equipment, and the VoLTE voice state information is used for indicating whether the user is carrying out voice VoLTE voice call on long term evolution or not, so that after receiving the user state information, the user data equipment sends the user state information to the service platform, and enables the service platform to determine whether the user is carrying out the VoLTE voice call based on the PS domain or not according to the VoLTE voice state information included in the user state information after receiving the user state information, and therefore, the VoLTE voice state of the user can be accurately determined; in addition, when the service platform is the false calling detection platform, the false calling detection platform indicates that the user is not the false calling user when determining that the user is carrying out the VoLTE voice call based on the PS domain, and therefore, whether the user is the false calling user can be accurately identified based on the VoLTE voice state information.
Preferably, the visited network element further includes a CS domain network element, and when the service platform determines that the user is attached to the CS domain, the user status query request is sent to the user data device, and then the user data device sends the user status query request to the CS domain network element, and the CS domain network element determines the user status information by using the prior art and returns the user status information to the user data device, and then the user data device sends the user status information to the service platform.
Based on the above description, a user status query method provided by the embodiment of the present invention is described next.
As shown in fig. 3, a schematic flow chart of a user status query method provided in an embodiment of the present invention may include the following steps:
s31, the service platform receives a user state request message aiming at a packet switching PS domain supporting VoLTE voice call.
Specifically, the gateway switch GMSC sends a service initiated by a user accessing the network to the service platform, so that the service platform can receive a service request initiated by the user, and then determines to receive a user status query message when it is determined that the service request is for a PS domain supporting VoLTE voice call. When the service platform of the present invention is a false caller id platform, the service request may be a call request.
Alternatively, the user data device in the present invention may be, but is not limited to, HLR, HSS or 5G UDM, etc.
Specifically, it may be determined whether the user is attached to the PS domain supporting VoLTE voice call according to the procedure shown in fig. 4, including the following steps:
s41, the service platform sends a domain selection request to the user data equipment.
In this step, the service platform sends a called Access Domain Selection (T-ADS) request to the user data device by using the Sh interface.
Specifically, the Service platform may be a Service Control Point (SCP) or an Application Server (AS). The SCP/AS may determine the domain to which the subscriber is attached by sending T-ADS information to the HLR/HSS/5G UDM using the Sh interface.
S42, the service platform receives the domain selection result returned by the user data equipment.
S43, if the service platform determines that the domain selection result is that the IMS voice based on the PS network is supported, determining that the user is attached to the PS domain supporting the VoLTE voice call.
In this step, if the domain selection result received by the service platform carries IMS-VOICE-OVER-PS-SUPPORTED (1), that is, supports VOICE OVER PS network, it is determined that the user is attached to the PS domain supporting VoLTE VOICE call. It should be noted that, if the user is attached to the PS domain supporting VoLTE voice call, the user may be an IMS user.
S32, the service platform sends a user state query request to the user data equipment.
When it is determined that the user is attached to the PS domain supporting the VoLTE voice call based on the procedure shown in fig. 4, a user status query request is sent to the user data device, where the request carries the attachment information of the user, for example, the user is attached to the PS domain supporting the VoLTE voice call.
And S33, the user data equipment sends the user state query request to the PS domain network element registered by the user.
In this step, after receiving the user status query request, the user data device may directly send the user status query to the PS domain network element based on the attachment information carried in the request, if the user data device is attached to the PS domain supporting the VoLTE voice call.
Specifically, the PS domain in the present invention may include, but is not limited to, a GPRS service Support Node (SGSN), a Mobility Management Entity (MME), a 5G Access and Mobility Management function (5G Access and Mobility Management function,5G AMF), and the like.
And S34, the PS domain network element inquires the user state information of the user, wherein the user state information comprises VoLTE voice state information.
The VoLTE voice state information in the invention is used for indicating whether the user is carrying out the VoLTE voice call based on the PS domain.
Specifically, a PS domain network element, such as an SGSN/MME, is configured to establish a bearer with a network side, when a user is a real calling user, the network side allocates a dedicated bearer to the user, and the dedicated bearer provides a voice over lte (voice over lte) voice call based on a PS domain for the user, so that the SGSN/MME determines whether a dedicated bearer providing the voice over lte voice call based on the PS domain for the user exists, and if so, adds an extension field in user state information, where the extension field is voice over lte voice state information. When the VoLTE voice state information can be IMS APN determined bearer _ Active, indicating that the IMS APN is established, it indicates that the user is performing a VoLTE voice call based on the PS domain, otherwise, the user does not perform the VoLTE voice call based on the PS domain. Specifically, the value of IMS APN determined bearer _ Active may be set according to an actual situation, for example, a value of 1 indicates that the IMS APN is established. The special bearer for the VoLTE voice call can be distinguished from VoLTE data, so that whether the user is carrying out the VoLTE voice call based on the PS domain can be determined definitely based on the VoLTE voice state information.
And S35, the PS domain network element sends the inquired user state information to the user data equipment.
And S36, the user data equipment sends the user state information to the service platform.
And S37, the service platform determines that the user is not a false user when determining that the user is carrying out the VoLTE call based on the PS domain according to the VoLTE voice state.
In this step, when the service platform determines that the VoLTE voice state information in the user state information is that the IMS APN dedicated bearer is established, that is, the IMS APN specified _ Active is activated, it is determined that the user is performing a VoLTE voice call based on the PS domain, and when the service platform is a false caller detection platform, the false caller detection platform may further determine that the user is not a false caller based on the VoLTE voice state information.
When the service platform determines that the user is attached to the CS domain, the steps S32 to S37 are not executed, but implemented according to the flow shown in fig. 5, including the following steps:
s51, when the service platform determines that the user is attached to the CS domain, the service platform sends a user state query request to the user data equipment.
And if the domain selection result returned to the service platform by the user data equipment is IMS-VOICE-OVER-PS-NOT-SUPPORTED (0), namely the user data equipment does NOT support the VOICE based on the PS network, determining that the user is NOT attached to the PS domain and is attached to the CS domain.
S52, the user data equipment sends the user state inquiry request to the CS domain network element registered by the user.
S53, the CS domain network element determines the user state information of the user.
And S54, the CS domain network element sends the user state information to the user data equipment.
And S55, the user data equipment sends the inquired user state information to the service platform.
And S56, the service platform determines whether the user is a false user according to the user state information.
Specifically, when it is determined that the user is attached to the CS domain, it indicates that the user does not perform a VoLTE voice call based on the PS domain, and a 2G network is used for performing a voice call, it may refer to the prior art to obtain user state information in the CS domain, and it may also refer to the prior art when determining whether the user is a false calling user, which is not described in detail herein.

By adopting the method, whether the user is currently carrying out the VoLTE voice call based on the PS domain can be accurately determined, and the false calling platform can identify whether the user is a false user.
