A cloud terminal call center data intelligent processing system and method

Abstract

The present application provides a cloud terminal call center data intelligent processing system and method, belonging to the field of communication technology. In this method, during a call via an IMS network, a cloud terminal can automatically notify the P-CSCF of its switch from a first operator network to a second operator network. Since the P-CSCF has pre-configured the cloud terminal's security mechanism for the second operator network, the P-CSCF can directly configure the cloud terminal with the security mechanism for the second operator network without notifying the S-CSCF. This allows the cloud terminal to perform network switching in an IMS scenario with fewer interacting network elements, more flexible signaling interactions, and lower overhead.

Description

Technical Field

[0001] The present application relates to the field of artificial intelligence, and in particular to a cloud terminal call center data intelligent processing system and method. Background Art

[0002] The Internet Protocol (IP)-based Multimedia Subsystem (IMS) network provides services such as packet voice, instant messaging, and video conferencing. The IMS network integrates communication services with a rich set of applications through programming interfaces, offering users a wider range of services. Core components of the IMS network include the proxy-call session control function (P-CSCF) and the serving-call session control function (S-CSCF). The P-CSCF is a key component of the IMS network, located between IMS terminals and the IMS network, similar to a proxy server serving as the input and output ports of an IM network. All requests initiated by IMS terminals and responses sent back by receiving terminals pass through the P-CSCF. The P-CSCF forwards SIP requests and responses in certain directions. In addition to accepting SIP user access and forwarding SIP messages, it also provides integrity protection, compression, and Quality of Service (QoS) policy decisions. The S-CSCF is the core node of the IMS signaling plane. The S-CSCF is responsible for allocating the home network S-CSCF (for user registration) and routing incoming IMS calls. As can be seen, the IMS network can provide data services to terminals, and is therefore also referred to as central data or a central data network.

[0003] In existing technology, when a terminal accesses an IMS network, if the terminal's accessed Public Land Mobile Network (PLMN), the P-CSCF needs to notify the S-CSCF of this change so that the S-CSCF can determine the terminal's security mechanism in the latest PLMN. However, this approach is relatively fixed and inflexible, and may not be able to meet future service needs. Summary of the Invention

[0041] The network architecture and business scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0042] The technical solution in this application will be described below with reference to the accompanying drawings.

[0043] See also Figure 1 , an embodiment of the present application provides a cloud terminal call center data intelligent processing system, which may include: P-CSCF and a cloud terminal.

[0044] The P-CSCF is located in the data center, which is the IMS network. Therefore, the P-CSCF can also be understood as the P-CSCF within the IMS network. A key component of the IMS network, the P-CSCF sits between IMS terminals and the IMS network, acting like a proxy server at the input and output ports of an IM network. All requests initiated by IMS terminals and responses sent back by receiving terminals pass through the P-CSCF. The P-CSCF forwards SIP requests and responses in certain directions. In addition to accepting SIP user inbound and outbound SIP message forwarding, it also provides integrity protection, compression, and QoS policy decision-making.

[0045] A cloud terminal can be understood as a terminal, such as a terminal deployed in the cloud. The terminal can be a terminal with a communication function, or can be a chip or chip system provided at the terminal. The terminal device can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The terminal device in the embodiment of the present application can be a mobile phone, a tablet computer, a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a vehicle-mounted terminal, an RSU with terminal function, etc.

[0046] The following describes in detail the interaction between the P-CSCF and the cloud terminal in the above system in combination with the method.

[0047] See also Figure 2 The present invention provides a method for intelligently processing cloud terminal call center data. The method can be applied to communications between a P-CSCF and a cloud terminal. The method includes the following steps:

[0048] S201 , when a cloud terminal is making a call via an IMS network, a P-CSCF receives a SIP message from the cloud terminal.

[0049] The SIP message is used to instruct the cloud terminal to switch from the first operator network to the second operator network. For example, the SIP message carries information indicating the old operator network and information indicating the new operator network, where the old operator network is the first operator network and the new operator network is the second operator network. The information indicating the old operator network and the information indicating the new operator network are used to jointly instruct the cloud terminal to switch from the first operator network to the second operator network. The first operator network is the first PLMN, and the second operator network is the second PLMN, i.e., different PLMNs.

[0050] It is understandable that in the prior art, cloud terminals (or terminals, i.e., UEs) do not inform the IMS network of updated network information when switching their own networks. Instead, the network side, such as the 5G core network, perceives the terminal's network switching, and then the PCF network element of the 5G core network informs it to the P-CSCF. Obviously, the embodiments of the present application enhance the terminal's processing logic, allowing the terminal to directly inform the IMS network without the involvement of the 5G core network, thereby simplifying the interaction and reducing overhead.

[0051] S202: The P-CSCF triggers the re-registration process of the cloud terminal.

[0052] Among them, the P-CSCF can send a SIP registration message to the S-CSCF. Among them, the SIP registration message is used to request that the cloud terminal be re-registered to the IMS network. Afterwards, the P-CSCF can receive a SIP response message from the S-CSCF. Among them, the SIP response message is a response to the SIP registration message, and the SIP response message is used to indicate that the cloud terminal has successfully re-registered to the IMS network, or that the cloud terminal has failed to re-register to the IMS network. In addition, the re-registration process of the cloud terminal (or terminal) (or the re-registration process in the IMS network) can also refer to the relevant protocol version of 3GPP, which will not be repeated here.

[0053] S203: If the re-registration is successful, the P-CSCF sends a security mechanism applicable to the second operator's network to the cloud terminal.

[0054] The security mechanism applicable to the second operator network for the cloud terminal refers to the security mechanism used by the cloud terminal to communicate with the IMS network in the second operator network.

[0055] Specifically, when the SIP response message is used to indicate that the cloud terminal has successfully re-registered with the IMS network, the P-CSCF encapsulates the security mechanism applicable to the second operator network of the cloud terminal into the SIP response message and sends the SIP response message to the cloud terminal.

[0056] For example, in response to a SIP response message indicating that the cloud terminal has successfully re-registered with the IMS network, the P-CSCF may obtain (e.g., locally) the security mechanism applicable to the second operator network for the cloud terminal. The P-CSCF re-registration process determines whether the security mechanism applicable to the second operator network for the cloud terminal is different from the security mechanism applicable to the first operator network for the cloud terminal, wherein the security mechanism applicable to the first operator network for the cloud terminal refers to the security mechanism used by the cloud terminal to communicate with the IMS network in the first operator network; if the security mechanism of the second operator network is different from the security mechanism applicable to the first operator network for the cloud terminal, the P-CSCF may encapsulate the security mechanism applicable to the second operator network for the cloud terminal into a SIP response message and send the SIP response message to the cloud terminal; otherwise, if the security mechanism of the second operator network is the same as the security mechanism applicable to the first operator network for the cloud terminal, the P-CSCF may directly forward the SIP response message received from the S-CSCF to the cloud terminal.

[0057] Optionally, the above security mechanism includes any one of the following: plaintext communication, symmetric encryption communication, asymmetric encryption communication, or homomorphic encryption communication.

[0058] Among them, plaintext communication refers to the cloud terminal using plaintext to communicate with the IMS network in its operating network, symmetric encryption communication refers to the cloud terminal using symmetric encryption to communicate with the IMS network in its operating network, asymmetric encryption communication refers to the cloud terminal using asymmetric encryption to communicate with the IMS network in its operating network, and homomorphic encryption communication refers to the cloud terminal using homomorphic encryption to communicate with the IMS network in its operating network.

[0059] Among them, symmetric encryption communication or asymmetric encryption communication can also be combined with homomorphic encryption communication. This combination means that the sending end can first symmetrically encrypt or asymmetrically encrypt the plaintext data of the call to obtain ciphertext data, and then homomorphically encrypt the ciphertext data to obtain homomorphic ciphertext; correspondingly, the receiving end can perform homomorphic calculation symmetric decryption or asymmetric decryption on the homomorphic ciphertext to obtain plaintext data in the homomorphic encrypted state, and then perform homomorphic calculation function operations on the plaintext data in the homomorphic encrypted state.

[0060] Optionally, before the P-CSCF receives the SIP message from the cloud terminal, the method includes initially registering the cloud terminal with the IMS network. For example, in the cloud terminal registration process (initial registration process), the P-CSCF may obtain the security mechanism applicable to the cloud terminal for the operator network set from the S-CSCF. The security mechanism applicable to the operator network set by the cloud terminal refers to the security mechanism used by the cloud terminal to communicate with the IMS network in any operator network in the operator network set, where the operator network set includes the first operator network and the second operator network. For example, the P-CSCF may receive a SIP registration message from the cloud terminal and send a SIP registration message (the SIP registration message in the initial registration process) to the S-CSCF, where the SIP registration message is used to request that the cloud terminal be registered with the IMS network. The P-CSCF receives a SIP response message from the S-CSCF (the SIP response message in the initial registration process). The SIP response message is a response to the SIP registration message. The SIP response message is used to indicate that the cloud terminal has successfully registered with the IMS network or that the cloud terminal has failed to re-register with the IMS network. In addition, if the cloud terminal has successfully registered with the IMS network, the SIP response message also carries the security mechanism applicable to the operator network set for the cloud terminal.

[0061] In summary, when the cloud terminal is making a call through the IMS network, the cloud terminal can automatically inform the P-CSCF of switching from the first operator's network to the second operator's network. Since the P-CSCF has pre-configured the security mechanism applicable to the cloud terminal in the second operator's network in advance, the P-CSCF can directly configure the security mechanism applicable to the second operator's network for the cloud terminal without informing the S-CSCF. As a result, when the cloud terminal performs network switching in the IMS scenario, fewer network elements can be interacted with, signaling interaction can be more flexible, and overhead can be lower.

[0062] Combination of the above Figure 2 The method provided by the embodiment of the present application is described in detail. The following introduces a cloud terminal call center data intelligent processing system for executing the method provided by the embodiment of the present application.

[0063] The system includes a P-CSCF in an IMS network. The system is configured as follows: during a call between a cloud terminal and an IMS network, the P-CSCF receives a SIP message from the cloud terminal, wherein the SIP message is used to instruct the cloud terminal to switch from a first operator network to a second operator network; the P-CSCF triggers a re-registration process for the cloud terminal; and when the re-registration is successful, the P-CSCF sends a security mechanism applicable to the cloud terminal for the second operator network to the cloud terminal, wherein the security mechanism applicable to the cloud terminal for the second operator network refers to a security mechanism used by the cloud terminal for calls between the cloud terminal and the IMS network in the second operator network.

[0064] Optionally, the above-mentioned SIP message carries information for indicating the old operator network and information for indicating the new operator network, wherein the old operator network is the first operator network and the new operator network is the second operator network, and the information for indicating the old operator network and the information for indicating the new operator network are used to jointly instruct the cloud terminal to switch from the first operator network to the second operator network.

[0065] The first operator network is a first PLMN, and the second operator network is a second PLMN.

[0066] Optionally, the system is configured as follows: the P-CSCF sends a SIP registration message to the S-CSCF, wherein the SIP registration message is used to request that the cloud terminal be re-registered to the IMS network; the P-CSCF receives a SIP response message from the S-CSCF, wherein the SIP response message is a response to the SIP registration message, and the SIP response message is used to indicate that the cloud terminal has successfully re-registered to the IMS network, or that the cloud terminal has failed to re-register to the IMS network.

[0067] Optionally, the system is configured to: when the SIP response message is used to indicate that the cloud terminal has successfully re-registered to the IMS network, the P-CSCF encapsulates the security mechanism applicable to the second operator network of the cloud terminal into the SIP response message and sends the SIP response message to the cloud terminal.

[0068] Optionally, the system is configured as follows: in response to a SIP response message indicating that the cloud terminal has successfully re-registered to the IMS network, the P-CSCF obtains a security mechanism applicable to the second operator network of the cloud terminal; the P-CSCF determines whether the security mechanism applicable to the second operator network of the cloud terminal is different from the security mechanism applicable to the first operator network of the cloud terminal, wherein the security mechanism applicable to the first operator network of the cloud terminal refers to the security mechanism used by the cloud terminal to communicate with the IMS network in the first operator network; if the security mechanism of the second operator network is different from the security mechanism applicable to the first operator network of the cloud terminal, the P-CSCF encapsulates the security mechanism applicable to the second operator network of the cloud terminal into a SIP response message and sends the SIP response message to the cloud terminal; otherwise, if the security mechanism of the second operator network is the same as the security mechanism applicable to the first operator network of the cloud terminal, the P-CSCF directly forwards the SIP response message received from the S-CSCF to the cloud terminal.
