Description

Technical Field

[0001] This application relates to the field of network transmission technology, and in particular to a session establishment method, apparatus, related equipment, storage medium, and computer program product. Background Technology

[0002] With the rapid development of artificial intelligence (AI) technology, research has been conducted on new services combining real-time communication and AI, and their corresponding characteristics; among them, AI real-time communication assistants are a feature of a new type of service that has attracted considerable attention. For example... Figure 1 As shown, users interact with AI entities (which can be expressed as Agents in English) and issue commands through natural language (such as voice). After recognizing the user's semantics (which can also be understood as the user's intent), the AI ​​entity calls other services to meet the user's needs.

[0003] From a technical implementation perspective, AI real-time communication assistants can be implemented either on a terminal or over a network. In the network-based implementation, the AI ​​entity is deployed within the network, allowing it to recognize user intent and invoke relevant services.

[0004] Because terminals are limited by computing power and power consumption, their AI processing capabilities are limited. However, network-based AI real-time communication assistants can support larger AI models, thus providing stronger service capabilities. Therefore, in scenarios involving network-based AI real-time communication assistants (such as those provided by telecom operators), such as... Figure 2 As shown, the related technologies propose a scheme to overlay AI entities on Voice over Long-Term Evolution (VoLTE) / VoNR (VoNR) networks, enabling users to interact with AI entities through the IP Multimedia Subsystem (IMS) network.

[0005] However, there is a problem of high network overhead during the process of users interacting with AI entities. Summary of the Invention

[0069] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0070] For AI real-time communication assistants, in the case of terminal-based implementation, the AI ​​entity can be deployed on the terminal. In this way, after the terminal recognizes the user's intent locally, it can directly call network services.

[0071] exist Figure 2 In the illustrated scheme, when a user needs to interact with an AI entity within the network, an IMS call (which can also be understood as a voice channel) needs to be established between the terminal and the IMS network. In current VoLTE / VoNR networks, such as... Figure 3 As shown, the signaling overhead during IMS call establishment is very high. If an IMS call is established every time a user interacts with an AI entity, the signaling overhead will increase significantly, and the latency will be difficult to meet business requirements. Therefore, a long-lived IMS call connection needs to be established between the terminal and the IMS network to reduce signaling overhead.

[0072] However, maintaining a persistent IMS call connection consumes network resources, resulting in significant network overhead. Specifically, during the establishment of an IMS call, network devices (such as Session Border Controllers (SBCs)) temporarily allocate port and IP resources for the IMS call as an endpoint for receiving real-time media streams, and release the occupied port resources after the call ends. Maintaining a persistent IMS call connection would exhaust the port resources of core network devices.

[0073] Therefore, there is currently no solution to reduce the network resource consumption of long IMS call connections, thereby reducing network overhead.

[0074] Based on this, in various embodiments of this application, when a terminal initiates a session between the terminal and the network side, the network side selects the port resources required for the session from the pre-configured port resources and establishes the session based on the selected port resources. This effectively reduces the occupation of network resources and thus reduces network overhead.

[0075] This application provides a session establishment method, such as... Figure 4 As shown, applied to the first network element, the method includes:

[0076] Step 401: Receive first information sent by the terminal, the first information being used to request the establishment of a first session for communication association between the terminal and the first entity, the first session being used for data transmission between the terminal and the first network element;

[0077] Step 402: Using the first information and the second information, determine the first port configured for the first network element corresponding to the first session, where the second information represents one or more ports configured for the first network element.

[0078] Step 403: Send third information to the terminal, the third information containing relevant information about the first port.

[0079] In practical applications, the first network element can be understood as a network element in the IMS network, such as the Proxy-Call Session Control Function (P-CSCF). This application embodiment does not limit the type of the first network element, as long as its function is implemented. In addition, the terminal can be called a user equipment (UE) or a user, etc. This application embodiment does not limit the name of the terminal, as long as its function is implemented.

[0080] In practical applications, in step 401, when the terminal determines that it needs to communicate with the first entity, the terminal can send the first information to the first network element to trigger the establishment of the first session. The first entity has at least the function of providing network services to the terminal, and the function is associated with AI, such as an AI entity. The first information can be sent through signaling (such as call signaling). This application embodiment does not limit the type of signaling. In this case, the terminal can send signaling to the first network element, and the signaling carries the first information.

[0081] Here, for the first session, a new session type (which may be called standby) can be predefined, and the type of session to be established can be indicated by the first information; wherein, in one embodiment, the first information represents the type of the first session.

[0082] In other words, based on the type represented by the first information, the first network element can know that the purpose of the terminal is to establish a first session of type standby (also known as a standby session).

[0083] In practical applications, after receiving the first information, the first network element can use one or more ports represented by the second information to select a corresponding first port for the first session; wherein, the second information may include information about one or more ports that the first network element has configured for the session for communication with one or more terminals and one or more first entities (which can also be understood as information about ports pre-configured by the network side for the standby type of session), and the information about each port may include port information and corresponding IP information.

[0084] Specifically, in one embodiment, the implementation of step 402 may include:

[0085] If the first network element is configured with a port, then the configured port will be designated as the first port.

[0086] Here, if only one port is configured for a standby session, the first network element can use that port as the first port and transmit data (such as media data) through the first port.

[0087] Specifically, in one embodiment, the implementation of step 402 may further include:

[0088] If the first network element is configured with multiple ports, select one port from the configured ports and designate the selected port as the first port.

[0089] In practical applications, if multiple ports are configured for standby sessions, the first network element can use a relevant algorithm (such as a round-robin algorithm or a hash algorithm, which is not limited in this embodiment) to select one port as the first port and transmit data through the first port.

[0090] In practical applications, after determining the first port, the first network element can send the third information to the terminal to establish the first session with the terminal. The first session may include a long-connection session, that is, after the session is established, it can be maintained for a period of time (which can be determined according to the duration of communication between the terminal and the first entity (e.g., 5 minutes or 1 day, which is not limited in this embodiment). In this way, it can avoid the need to temporarily establish a session every time the terminal and the first entity communicate, and reduce the signaling overhead in the session establishment process.

[0091] In practical applications, during the establishment of the first session, the first network element can also record the correspondence between port-related information on the network side and the terminal side, so that subsequent data transmission between the terminal and the first network element can be realized based on the recorded correspondence.

[0092] Specifically, in one embodiment, the first information may further include information related to the second port configured on the terminal corresponding to the first session and fourth information, wherein the fourth information is used to identify the terminal, and the method may further include:

[0093] Using the first information and the relevant information of the first port, fifth information is generated. The fifth information represents the correspondence between the relevant information of the second port, the relevant information of the first port, and the fourth information. The fifth information is used to realize data transmission between the terminal and the first entity.

[0094] In practical applications, the relevant information of the second port may include the second port information and the corresponding IP information. The fourth information can be understood as the identification information of the terminal, such as the terminal code number. This application embodiment does not limit the content of the fourth information, as long as its function is implemented.

[0095] In practical applications, by associating the relevant information of the second port, the relevant information of the first port, and the fourth information, the first network element can obtain and store the fifth information. Upon receiving subsequent data packets, the first network element can then perform data transmission between the terminal and the first entity based on the fifth information.

[0096] Based on this, in one embodiment, the method may further include:

[0097] Receive one or more data packets;

[0098] Using the fifth piece of information, one or more data packets are sent to the first entity.

[0099] In practical applications, the first network element can receive one or more data packets sent by one or more terminals based on relevant protocols; wherein, if the relevant protocol includes Real-time Transport Protocol (RTP), the data packet type can include RTP data packets. That is, the one or more data packets can be sent by different terminals through one or more sessions associated with communication between the terminals and the first entity.

[0100] Here, using the fifth information, the first network element can determine the terminal to which each data packet belongs, and thus transmit the data packet to the first entity corresponding to the terminal.

[0101] Specifically, in one embodiment, sending the one or more data packets to the first entity using the fifth information includes:

[0102] For each of the one or more data packets, determine the relevant information of the second port and the relevant information of the first port corresponding to the data packet;

[0103] Using the fifth piece of information, the identifier-related information of the terminal associated with the relevant information of the second port and the relevant information of the first port is determined;

[0104] Send data packets to the first entity corresponding to the determined terminal.

[0105] In practical applications, for each data packet transmitted between the terminal and the first network element, the first network element can determine the relevant information of the corresponding second port and the relevant information of the first port through the session associated with the data packet; wherein, the first port and the second port can be understood as the ports involved in the transmission of each data packet between the terminal and the first network element.

[0106] For example, when terminal 1 transmits data packet 1 through the first session, the first network element can determine the relevant information of the first port 1 and the relevant information of the second port 1 corresponding to the first session; when terminal 2 transmits data packet 2 through the second session, the first network element can determine the relevant information of the first port 2 and the relevant information of the second port 2 corresponding to the second session.

[0107] Next, using the fifth information, the first network element can determine the terminal identification information associated with the relevant information of the second port and the relevant information of the first port, thereby determining the terminal to which the data packet belongs. Since the first network element establishes data transmission channels between the first entity and the first network element for different terminals, and generates a correspondence between the identification information of different terminals and the relevant information of the third port corresponding to the established channels, the first network element can determine the relevant information of the third port corresponding to the data packet using the terminal identification information, and thus send the data packet to the corresponding first entity based on the relevant information of the third port.

[0108] In related technologies, since IMS calls use Guaranteed Bit Rate (GBR) bearer, after an IMS call is successfully established, the network side will reserve corresponding air interface resources for the user. This means that regardless of whether the terminal continuously sends media streams (which can also be understood as media data), these resources will not be used by other services or other users. In this case, maintaining a long IMS call connection will cause the occupation of air interface resources.

[0109] To address the aforementioned issues, the first network element can establish a new non-GBR bearer to carry the data transmission of the first session. In this way, when the terminal is not sending data, these resources can be used by other services or terminals, thereby reducing the occupation of air interface resources.

[0110] Based on this, in one embodiment, the method may further include:

[0111] Establish a non-GBR bearer and use the non-GBR bearer to carry data transmission associated with the first session.

[0112] In practical applications, the first network element can also use the established bearer to carry the data transmission of the first session, thus avoiding the occupation of additional wireless resources.

[0113] Based on this, in one embodiment, the method may further include:

[0114] The established first bearer is used to carry data transmission associated with the first session, and the first bearer is capable of carrying signaling transmission.

[0115] In practical applications, the first bearer can carry the transmission of signaling (such as IMS signaling). The first bearer can be established after the terminal registers in the network side. This application embodiment does not limit the type of the first bearer, as long as its function is implemented.

[0116] In other words, the first network element can utilize a first bearer capable of carrying signaling transmission to carry media transmission for the first session.

[0117] In practical applications, after step 403, upon receiving the sixth information sent by the terminal, the first network element can also clear the stored fifth information and release the data transmission channel associated with the terminal for data transmission between the first entity and the first network element. The sixth information is used to request the release of the first session, thereby releasing the resources of the first session and reducing the occupation of network resources.

[0118] Accordingly, embodiments of this application also provide a session establishment method, such as... Figure 5 As shown, applied to a terminal, the method includes:

[0119] Step 501: Send first information to the first network element, the first information being used to request the establishment of a first session for communication association between the terminal and the first entity, the first session being used for data transmission between the terminal and the first network element;

[0120] Step 502: Receive third information sent by the first network element, wherein the third information contains relevant information about the first port configured by the first network element corresponding to the first session.

[0121] The session establishment method provided in this application embodiment involves a first network element receiving first information sent by a terminal. This first information requests the establishment of a first session associated with communication between the terminal and a first entity. The first session is used for data transmission between the terminal and the first network element. Using the first and second information, a first port configured on the first network element corresponding to the first session is determined. The second information represents one or more ports already configured on the first network element. Third information is sent to the terminal, containing relevant information about the first port. The technical solution provided in this application embodiment, during communication between the terminal and a first entity (e.g., an AI entity), allows the first network element to select port resources corresponding to the session between the terminal and a network element in the network (e.g., an IMS network) from pre-configured port resources to establish the session. This process uses fixed-configuration network resources to establish the session without consuming additional network resources, thus reducing network overhead.

[0122] The following section provides a more detailed description of this application with reference to application examples.

[0123] In the application examples of this application, a new session type (i.e., standby session) is defined, and a scheme for establishing standby sessions is proposed.

[0124] Specifically, the process of establishing a standby session, such as Figure 6 As shown, it includes the following steps:

[0125] Step 601: The terminal sends a call request (which can be expressed as INVITE) to the network element in the IMS network (i.e., the first network element mentioned above). The call request carries at least the port information and IP information of the terminal side (i.e., the relevant information of the second port mentioned above), the standby session indication information (i.e., the first information mentioned above), and the Uniform Resource Identifier (URI) information of the standby session. The standby session indication information is used to indicate that the purpose of the current call is to establish a standby session, and the URI information of the standby session is used to identify the AI ​​entity called by the terminal (i.e., the first entity mentioned above).

[0126] Step 602: After receiving the call request, the network element in the IMS network sends a 200 OK response to the terminal (i.e., the third information mentioned above);

[0127] Here, after receiving a call request, the network element in the IMS network selects the endpoint information (i.e., the relevant information of the first port mentioned above) for the standby session from one or more pre-configured endpoint information (composed of port information and IP information), and then sends a 200 OK response to the terminal. The 200 OK response carries the endpoint information selected by the network side. For the standby session, a fixed endpoint can be used to send and receive real-time media, or an endpoint can be assigned to the standby session for each call using a polling or hashing method to send and receive real-time media.

[0128] In addition, when a terminal initiates a standby session, network elements in the IMS network can use the IMS signaling bearer (i.e., the first bearer mentioned above) to carry the media transmission of the standby session, or use a newly established non-GBR bearer to carry the media transmission of the standby session.

[0129] Step 603: During the standby session establishment process, the network elements in the IMS network record the correspondence between the terminal-side endpoint, the network-side endpoint, and the terminal identifier (i.e., the fifth information mentioned above), and then execute step 604.

[0130] Step 604: The network elements in the IMS network establish a media channel from the network element to the AI ​​entity for the terminal;

[0131] Step 605: The terminal sends an RTP stream to a network element in the IMS network;

[0132] Step 606: Network elements in the IMS network forward RTP flows according to the correspondence of records.

[0133] Here, network elements in the IMS network determine the terminal to which each data packet in the RTP stream belongs based on the recorded correspondence, and then forward the data packet to the AI ​​entity through the corresponding media channel.

[0134] Additionally, the process of releasing a standby session, such as... Figure 7 As shown, it includes the following steps:

[0135] Step 701: The terminal sends a disconnect request (which can be expressed as BYE in English) to the network element in the IMS network. The disconnect request carries at least the URI information of the standby session.

[0136] Step 702: After receiving the disconnection request, the network element in the IMS network clears the recorded correspondence between the terminal-side endpoint, the network-side endpoint, and the terminal identifier, and then executes step 703;

[0137] Step 703: The network element in the IMS network sends a 200 OK response to the terminal;

[0138] Step 704: The network element in the IMS network releases the media channel from the network element to the AI ​​entity for the terminal.

[0139] In the application example of this application, one or more ports are pre-configured on the network side specifically for standby sessions. In this way, while meeting the service requirements of AI real-time communication assistant, the network resource consumption of establishing standby sessions between the terminal and the IMS network can be effectively reduced.

[0140] To implement the method of the embodiments of this application, the embodiments of this application also provide a session establishment device, which is disposed on a first network element, such as... Figure 8 As shown, the device includes:

[0141] The first receiving unit 801 is used to receive first information sent by the terminal. The first information is used to request the establishment of a first session for communication association between the terminal and the first entity. The first session is used for data transmission between the terminal and the first network element.

[0142] The determining unit 802 is used to determine the first port configured by the first network element corresponding to the first session using the first information and the second information, wherein the second information represents one or more ports configured by the first network element.

[0143] The first sending unit 803 is used to send third information to the terminal, the third information including relevant information of the first port.

[0144] In one embodiment, the determining unit 802 is used to determine a configured port as the first port when the first network element is configured with a port.

[0145] In one embodiment, the determining unit 802 is configured to select one port from the configured ports when the first network element is configured with multiple ports, and determine the selected port as the first port.
