[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Combine the following Figures 1 to 10 The present invention describes a method and device for reducing the detour of IMS call traffic for private communication.

[0051] like Figure 1 As shown, in one embodiment, a method for reducing the detour of IMS call traffic for private communication is applied to a private communication platform, and includes the following steps:

[0052] Step S110, receiving a private communication call message from the I-SBC address, where the private communication call message is obtained by the I-SBC address responding to the private communication call request sent by the user end and encapsulating the private communication call request according to a set format.

[0053] Specifically, the calling user first sends a private communication call request to the I-SBC address. The I-SBC address responds to the private communication call request by encapsulating the private communication call request according to the set format to obtain a private communication call message, and then sends the obtained private communication call message to the private communication platform.

[0054] Step S120: parsing the called number in the private communication call request based on the private communication call message, and acquiring the location information of the called number through the number location query unit.

[0055] Specifically, the privacy communication platform parses the called number in the privacy communication call request based on the received privacy communication call message, and quickly obtains the location information of the called number through the national number location query system.

[0056] Step S130, calculating the routing path of the private communication call according to the routing decision parameter table to generate a routing instruction, and sending the routing instruction to the I-SBC address of the call initiator, or the target I-SBC address of the called number, to establish a communication session between the call initiator user terminal and the called number user terminal.

[0057] Specifically, the privacy communication platform calculates the optimal routing path for the privacy communication call according to the preset routing decision parameter table to generate the corresponding routing instructions, and sends the routing instructions to the I-SBC address that initiates the call, or the target I-SBC address of the called number. After receiving the routing instructions, the I-SBC address that initiates the call or the target I-SBC address responds to the routing instructions and establishes a communication session between the calling user end and the called number user end according to the calculated optimal routing path.

[0058] It should be noted that, based on the current network and routing load and network status, multiple routing paths that can establish a communication session with the target I-SBC address of the called number are selected from the preset decision parameter table. At the same time, in order to ensure that the time for establishing a communication session between the calling user terminal and the called number user terminal is the shortest and the network status is the most stable during the communication session, the optimal routing path is selected from the pre-selected multiple routing paths to establish a communication session between the calling user terminal and the called number user terminal.

[0059] Among them, the routing instructions include but are not limited to the target I-SBC address, port number, location information of the called number and the corresponding authentication information in the privacy communication call request, which are used to instruct the called number user end to establish a communication session with the calling user end. The routing decision parameter table includes but is not limited to network status monitoring indicators and load balancing.

[0060] The above method for reducing the traffic detour of the privacy communication IMS call is obtained by receiving a privacy communication call message from the calling I-SBC address, which is obtained by encapsulating the privacy communication call request sent by the calling I-SBC address in response to the privacy communication call request sent by the user end and in accordance with the set format. Subsequently, the called number in the privacy communication call request is parsed based on the privacy communication call message, and the location information of the called number is obtained through the number location query unit. Finally, the routing path of the privacy communication call is calculated according to the routing decision parameter table to generate a routing instruction, and the routing instruction is sent to the I-SBC address of the call initiator or the target I-SBC address of the called number to establish a communication session between the calling user end and the called number user end. This method can reduce traffic detours by directly routing the call request to the I-SBC address of its location after the called number is converted when the called party and the calling party are not in the same location, thereby improving communication efficiency and network resource utilization to a certain extent.

[0061] See also Figure 2 As shown, in a specific embodiment, the method for reducing the detour of IMS call traffic for privacy communication provided by the present invention, the system architecture implemented by the method includes the following key components:

[0062] Privacy communication platform: responsible for receiving privacy call requests from I-SBCs in various locations, performing number conversion, and intelligently selecting the optimal call routing path based on the location information of the called number.

[0063] National Number Location Query System: uses distributed database technology to store the mapping relationship between telephone numbers and locations across the country, providing efficient and accurate number location query services.

[0064] I-SBC in each location: As the communication access point of each location, it is responsible for call access, forwarding and session management within the corresponding location. At the same time, it maintains real-time communication with the privacy communication platform, receives and executes the routing instructions issued by it.

[0065] Intelligent routing decision module: integrated into the privacy communication platform, it comprehensively considers factors such as network status, load balancing, routing cost and security, and calculates and selects the optimal routing path for each privacy call.

[0066] It should be noted that the I-SBC address refers to the address of the Internet Services Border Control, which is a dedicated IP address range used to identify the edge location of the network.

[0067] In this embodiment, the method for reducing the detour of IMS call traffic for private communication provided by the present invention includes the following steps:

[0068] (1) The caller initiates a call.

[0069] The calling user initiates a private communication call through a terminal device, and the private communication call is firstly routed to the I-SBC in the calling user's home location.

[0070] (2) I-SBC initial processing and forwarding.

[0071] The I-SBC at the corresponding location performs preliminary processing on the received privacy communication call. After identifying the privacy communication request, it encapsulates the privacy communication request into a message in a specific format and forwards it to the privacy communication platform.

[0072] (3) Privacy communication platform processing.

[0073] The privacy communication platform receives privacy call requests from I-SBCs in various locations, parses the called number in the privacy call request, and uses the national number location query system to quickly obtain the location information of the called number. Subsequently, the intelligent routing decision unit is called to calculate the optimal routing path for the current privacy communication call in combination with the routing decision parameter table. The corresponding routing instructions are then generated, including the address, port number, and necessary authentication information of the target I-SBC, and then the routing instructions are returned to the I-SBC that initiated the call or sent directly to the target I-SBC.

[0074] The location information of all called numbers is stored in the number location data table, which uses a distributed hash table or distributed database storage to support high-concurrency queries and ensure fast acquisition of number location information. The routing decision parameter table contains routing decision parameters such as network status monitoring indicators and load balancing.

[0075] (4) Directly route to the called party’s home I-SBC.

[0076] If the routing instruction is sent directly to the target I-SBC, the I-SBC directly accesses the called user to establish a communication session.

[0077] If the routing instruction is returned to the I-SBC that initiated the call, the I-SBC will forward the private communication call to the target I-SBC according to the routing instruction, and the target I-SBC will then access the called user.

[0078] (5) Communication process and session management.

[0079] During the process of private communication between users of both parties, the private communication platform and the I-SBCs at each location are responsible for real-time management and monitoring of the sessions to ensure the stability and security of the communication process.

[0080] (6) Communication ends and resources are released.

[0081] After the private communication ends, the called party's home I-SBC releases the session resources and notifies the private communication platform and related I-SBCs to update the session status.

[0082] In this embodiment, after the called number is converted, the call can be directly routed to the ISBC of the province to which it belongs according to the location information of the called number, thereby reducing the detour of traffic. In addition, by using an efficient number location query system, the location of the called number can be quickly and accurately queried, and the optimal call routing path can be intelligently selected by combining the number location information and the network status. Therefore, the method can effectively reduce the detour of traffic and improve the communication efficiency and the utilization rate of network resources by directly routing the call request to the I-SBC of the location to which the called number belongs after the called number is converted.

[0083] like Figure 3 As shown, in one embodiment, the method for reducing the private communication IMS call traffic detour provided by the present invention receives a private communication call message from an I-SBC address, and before that, includes the following steps:

[0084] Step S310: receiving a private communication call initiated by a user terminal through an I-SBC address, and identifying the private communication call.

[0085] Step S320: When a privacy communication call request in a privacy communication call is identified, the privacy communication call request is encapsulated into a privacy communication call message according to a set format, and the privacy communication call message is forwarded to the privacy communication platform.

[0086] like Figure 4 As shown, in one embodiment, the method for reducing the detour of private communication IMS call traffic provided by the present invention parses the called number in the private communication call request based on the private communication call message, and obtains the location information of the called number through the number location query unit, specifically including the following steps:

[0087] Step S122, receiving private communication call messages from I-SBC addresses of multiple different locations, and parsing the called number in the private communication call message corresponding to each location to obtain a parsing result.

[0088] Step S124, obtaining location information corresponding to each called number through the number location query unit.

[0089] The parsing result includes the target I-SBC address and port number of the called number and the corresponding authentication information in the privacy communication call request, and multiple location information is stored in a distributed hash table or a distributed database.

[0090] like Figure 5 As shown, in one embodiment, the method for reducing the detour of the private communication IMS call traffic provided by the present invention calculates the routing path of the private communication call according to the routing decision parameter table to generate a routing instruction, and sends the routing instruction to the I-SBC address of the call initiator or the target I-SBC address of the called number to establish a communication session between the call initiator user terminal and the called number user terminal, specifically including the following steps:

[0091] Step S132, calling the intelligent routing decision unit to calculate the routing path of the private communication call according to the network status monitoring index and load balancing, and generating a routing instruction based on the routing path.

[0092] The routing instruction is used to instruct the called number user terminal or the target I-SBC address to establish a communication session with the calling user terminal according to the optimal routing path selected in the decision parameter table.

[0093] It should be noted that the intelligent routing unit selects multiple routing paths that can establish a communication session with the target I-SBC address of the called number from a preset decision parameter table based on the current network and routing load and network status. At the same time, in order to ensure that the time for establishing a communication session between the calling user terminal and the called number user terminal is the shortest and the network status is the most stable during the communication session, the optimal routing path is selected from the pre-selected multiple routing paths to establish a communication session between the calling user terminal and the called number user terminal.

[0094] Step S134, when the routing instruction is sent to the target I-SBC address, the target I-SBC address is directly connected to the user terminal corresponding to the called number to establish a communication session between the calling user terminal and the called number user terminal.

[0095] like Figure 6 As shown, in one embodiment, the method for reducing the detour of the private communication IMS call traffic provided by the present invention calculates the routing path of the private communication call according to the routing decision parameter table to generate a routing instruction, and sends the routing instruction to the I-SBC address of the call initiator, or the target I-SBC address of the called number, to establish a communication session between the call initiator user terminal and the called number user terminal, and specifically includes the following steps:

[0096] Step S136: When the routing instruction is returned to the I-SBC address that initiated the call, the private communication call is forwarded to the target I-SBC address according to the routing instruction through the I-SBC address.

[0097] Step S138: Connect the target I-SBC address to the called number user terminal to establish a communication session between the calling user terminal and the called number user terminal.

[0098] like Figure 7 As shown, in one embodiment, the method for reducing the detour of the private communication IMS call traffic provided by the present invention calculates the routing path of the private communication call according to the routing decision parameter table to generate a routing instruction, and sends the routing instruction to the I-SBC address of the call initiator or the target I-SBC address of the called number to establish a communication session between the call initiator user terminal and the called number user terminal, and then includes the following steps:

[0099] Step S710, during the communication session between the calling user terminal and the called number user terminal, the communication session is monitored in real time according to the network status monitoring index and load balancing through the target I-SBC address.

[0100] Step S720, after the communication session ends, the target I-SBC address is controlled to release the session resources corresponding to the communication session, and feedback is given to the privacy communication platform and the I-SBC address that initiated the call to update the session status.

[0101] like Figure 8 As shown, in one embodiment, the method for reducing the detour of IMS call traffic for privacy communication provided by the present invention further includes the following steps:

[0102] Step S810: When the called number is converted, the location information of the new called number is obtained, and the private communication call corresponding to the new called number is routed to the new target I-SBC address of the corresponding location.

[0103] Step S820: Connect the new target I-SBC address to the called number user terminal to establish a communication session between the calling user terminal and the user terminal corresponding to the new called number.
