In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0103] The following is combined with Figures 1 to 6 , a communication method provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0104] like Figure 1 As shown, it is a flow chart of a communication method provided by an embodiment of the present application. Figure 1 As shown, the communication method is applied to a 5G message node, hereinafter referred to as the first 5G message node, and the communication method may include: the contents shown in S101 to S102.

[0105] In S101, a first 5G message sent by a first terminal is received, and the first 5G message is sent to a second terminal according to the phone number of the second terminal contained in the first 5G message.

[0106] In other words, this application does not require additional applications, only some information about the terminal device itself, such as phone number, etc., and terminal devices can be added through 5G messages.

[0107] In this embodiment, the first 5G message can be sent to the second terminal based on the telephone number of the second terminal contained in the first 5G message.

[0108] In S102, a second 5G message sent by the second terminal is received, and according to the phone number of the first terminal contained in the second 5G message, the second 5G message is sent to the first terminal. The second 5G message is a 5G message returned by the second terminal agreeing to add a friend or a 5G message returned by the second terminal refusing to add a friend.

[0109] In this embodiment, the first terminal can send a message to the second terminal via a 5G message, and correspondingly, the second terminal can also send a message to the first terminal via a 5G message. That is to say, the first terminal and the second terminal can communicate via a 5G message without using a third-party application, and use a telephone number to communicate during the communication process to ensure the security of the communication.

[0110] In an embodiment of the present application, a first 5G message sent by a first terminal is first received, and according to the phone number of the second terminal contained in the first 5G message, the first 5G message is sent to the second terminal, and then a second 5G message sent by the second terminal is received, and according to the phone number of the first terminal contained in the second 5G message, the second 5G message is sent to the first terminal, and the second 5G message is a 5G message returned by the second terminal agreeing to add a friend or a 5G message returned by the second terminal refusing to add a friend. Based on the 5G message, the embodiment of the present application performs communication such as adding friends between the two based on the phone number of the first terminal and the phone number of the second terminal. Since the phone number is authenticated by real name, the security issue of the user's real identity source is effectively solved.

[0111] In a possible implementation of the present application, receiving a first 5G message sent by a first terminal, and sending the first 5G message to a second terminal according to the phone number of the second terminal contained in the first 5G message, may include: receiving a first 5G message for adding a friend sent by the first terminal; parsing the first 5G message as a social message for adding a friend, the first 5G message including a first message interaction encryption public key, the phone number of the second terminal and the phone number of the first terminal; and sending the first 5G message to the second terminal according to the phone number of the second terminal.

[0112] That is to say, when receiving the first 5G message for adding a friend sent by the first terminal, the first 5G message can be parsed to determine that the message is a social message for adding a friend, and the first 5G message can be sent to the second terminal according to the phone number contained in the message. The message interaction between the terminals can be completed through the phone number, making the message interaction safe and convenient.

[0113] In a possible implementation of the present application, receiving a second 5G message sent by a second terminal, and sending the second 5G message to the first terminal according to the phone number of the first terminal contained in the second 5G message, may include: receiving the second 5G message sent by the 5G message node of the second terminal; parsing the second 5G message, determining that the second 5G message is a 5G message of agreement to add a friend, and the second 5G message includes a second message interaction encryption public key; based on the second 5G message, updating and saving the friend relationship information, as well as the first message interaction encryption public key and the second message interaction encryption public key; sending the 5G message of agreement to add a friend and the second message interaction encryption public key to the first terminal.

[0114] That is to say, when the second 5G message sent by the second 5G message node of the second terminal is received, the message is parsed to determine that the second 5G message is a 5G message in which the second terminal agrees to add a friend and the second message interaction encryption public key of the second terminal. The first 5G message node updates and saves the friend relationship information between the first terminal and the second terminal, as well as the first message interaction encryption public key and the second message interaction encryption public key, for subsequent use by the first terminal and the second terminal in communication, and sends the 5G message in which the second terminal agrees to add a friend and the second message interaction encryption public key to the first terminal to complete the addition of friends between the first terminal and the second terminal.

[0115] In a possible implementation of the present application, the 5G message node includes a first 5G message center 5GMC and a first 5G message commercial network element MaaP (Massage as a platform).

[0116] Receiving a first 5G message sent by a first terminal, and sending the first 5G message to a second terminal according to the phone number of the second terminal contained in the first 5G message, may include: a first 5GMC receives the first 5G message sent by the first terminal, and sends the first 5G message to a first MaaP; the first MaaP parses the first 5G message, determines that the first 5G message is a social message for adding a friend, and the first 5G message includes a first message interaction encryption public key, the phone number of the second terminal and the phone number of the first terminal; the first MaaP sends the first 5G message to a 5G message node corresponding to the second terminal according to the phone number of the second terminal.

[0117] It is worth noting that the 5GMC in the 5G message node is responsible for individuals and uplinks and downlinks personal messages; MaaP is responsible for uplinks and downlinks of 5G commercial messages. 5GMC and MaaP each have multiple regional nodes, which carry users in various regions across the country.

[0118] Figure 2 This is a schematic diagram of a social friend system based on 5G messages. 5GMC may include a personal information module, a social friend module, and a personal friend circle module, and MaaP includes a social message communication module.

[0119] Among them, the personal message module is responsible for adding, deleting, modifying and checking the user's 5G message personal information, including personal nickname, personal avatar, personal status, personal signature, personal background and other information; the social friend module is responsible for adding, deleting, modifying and checking the user's 5G message friend relationship information, including friend's number, friend's notes and other information, realizing functions such as message forwarding between friends and message authentication verification; the personal circle of friends module is responsible for adding, deleting, modifying and checking the user's circle of friends information, supporting a variety of rich media forms, including text, pictures, videos, cards and other information. The social message communication module is responsible for the user's functions such as adding friend notifications, deleting friend notifications, sending circle of friends notifications, etc.

[0120] Among them, the 5G message node where the first terminal UE1 is located includes 5GMC1 and MaaP1, and the 5G message node where the second terminal UE2 is located includes 5GMC2 and MaaP2.

[0121] In other words, the system mainly includes a personal information module, a social friend module, and a personal circle of friends module based on 5G messages. The system uses the Authentication and Key Agreement (AKA) authentication and authentication of the third-generation mobile communication network of 5G messages as the user login mechanism, and uses the Session Initialization Protocol (SIP) of the 5G message Subscriber Identity Module (SIM) card information and the Hypertext Transfer Protocol (HTTP) authenticated by the Generic Bootstrapping Architecture (GBA) to expand the communication and social functions of the device while ensuring the true identity of the user.

[0122] In this embodiment, in response to the user clicking the add friend button, the 5G message pops up the address book user interface, and based on the user selected by the user, the chatbot's friend system pops up to assemble the add friend information.

[0123] Specifically, when the 5G messaging application of the first terminal receives a click operation of the first user on the add friend button, the 5G messaging application calls up the system address book application, and the first terminal pops up a user interface for selecting the address book. When the first user selects the address book user interface, the 5G messaging application pops up the official Chatbot friend system, and the 5G messaging application automatically assembles a message for adding friends. The 5G messaging application is an application on the terminal, which can perform operations such as adding friends based on the terminal number.

[0124] In one example of this application, the message format may be as follows:

[0125] {

[0126] "reply":{

[0127]

[0128] Among them, displayText is the input display content of the sent message; Postback is the data information carried by the sent message, type = add_friend indicates a request to add a friend, sendId indicates the sender number, and receiverId indicates the receiver number; msgPublicKey indicates the first message interaction encryption public key, which is used to securely encrypt the interactive messages between users' social friends when the sender sends a message to the receiver to prevent information leakage. In other embodiments, the message format can also be in other forms, which are subject to actual application and are not limited in this embodiment.

[0129] In one example, the msgPublicKey generation algorithm at the UE terminal is as follows:

[0130] 1) The first terminal UE1 establishes a key coefficient library

[0131] The first terminal UE1 selects the addition clusters W1 and W2 on the elliptic curve, the generator of the W1 cluster is p, and the order is q greater than or equal to 2 l , where l is the safety factor and the generator of the W2 cluster is p.

[0132] Terminal UE1 selects bilinear mapping e: W1*W2→W2, hash function F1: {0,1} * →W1 * , F2: {0,1} * →Z q * , F3: W2→Z q * , F4: W1→Z q * , in Z q * Select the master key X∈Z q * , and calculate the corresponding public key Y=xP.

[0133] The key coefficient library constructed by the terminal UE1 is {W1, W2, q, p, e, F1, F2, F3, F4, Y}.

[0134] 2) Generate a public key and a private key corresponding to the second terminal of the second user, and feed the generated public key back to the second terminal

[0135] The first terminal UE1 generates a public key and a private key corresponding to the second terminal based on the number of the second terminal, wherein the public key is T 公1 =F1(ID2), private key is T 私1 =xF1(ID2), and record and store.

[0136] The purpose of generating public and private keys between friends is to encrypt based on the SIP protocol to ensure the security and reliability of messages between friends.

[0137] Optionally, in response to the first user clicking "send" in the chatbot's friend system, the assembled message is sent to the first MaaP (MaaP1), and the social message communication module of MaaP1 assembles a new add friend message based on the first user's personal information and sends it to the second terminal UE2 of the second user, so that the second terminal UE2 can determine whether to add a friend based on the add friend message, and return to the first 5G message node of the first terminal.

[0138] Specifically, after the first user clicks send in the chatbot's friend system, the assembled message is sent to the first 5GMC (5GMC1) of the node where the first user is located, and 5GMC1 sends the message to MaaP1; the social message communication module of MaaP1 receives the message sent by the first user to the chatbot's friend system, parses and identifies the message content to confirm that the message is a social message for adding friends, and then assembles a new friend-adding message based on the initiator's personal information and sends it to the second user, and the message is sent to the second MaaP (MaaP2) of the node where the second user is located.

[0139] The assembled message may be a single-card message, the card image of the message is the avatar of the first user, and the message body is "XX user, number XXX, requests to add you as a friend".

[0140] It should be noted that the message may carry two suggested reply buttons, one button is an approval button, and the other button is a rejection button.

[0141] The first MaaP delivers the message to the second MaaP where the second terminal is located. The second MaaP sends the message to the second 5GMC (5GMC2), and 5GMC2 sends it to the 5G message application of the second terminal UE2, so that the second terminal determines whether to agree to add the first terminal as a friend based on the above message.

[0142] In a possible implementation of the present application, the communication method may also include: when the first 5GMC receives a third 5G message sent by the first terminal to publish a circle of friends, the third 5G message sends the third 5G message to the first MaaP, and the third 5G message includes at least one of text, pictures, and videos; the first MaaP parses the third 5G message and determines that the third 5G message is a published circle of friends message; the first MaaP sends a request for obtaining a friend list of the first terminal to the first 5GMC; when the first 5GMC receives the request for obtaining a friend list of the first terminal, it queries the friend number list of the first terminal and sends the friend number list to the first MaaP; the first MaaP encrypts the circle of friends message using the first message interaction encryption public key, and sends the encrypted circle of friends message to the 5G message node where each terminal in the friend number list is located.

[0143] That is to say, the first user can post a circle of friends message in the 5G message application, and can synchronize the message to the terminals of other users who have a friend relationship with the first user.

[0144] In one example, first, in response to the user selecting content to be posted to Moments, the 5G messaging application assembles the message to be sent and sends it to the 5GMC.

[0145] The first terminal receives an operation of the first user to open the friend system interface of the Chatbot of the 5G message application. The first terminal opens the friend system interface of the Chatbot. The friend system interface of the Chatbot receives the content of the circle of friends message input by the first user. The content can be in the format of text, picture, video, etc. The first terminal uplinks the circle of friends message to 5GMC1, and 5GMC1 sends the message to MaaP1.

[0146] Secondly, MaaP1 receives and identifies the uplink friend circle message sent by UE1, and obtains the corresponding friend list interactive message public key T 公 , encrypt the message content and send it to each friend user.

[0147] The social message communication module of MaaP1 identifies the message as a friend circle message, and sends a request to the node 5GMC1 where the initiator of the message is located to obtain the friend list of the user; after receiving the request, the social friend module of 5GMC1 queries the friend number list and sends it to MaaP1; after receiving the friend number list of the user, MaaP1 uses the T 公 After encryption, it is forwarded to the MaaP where each friend is located; after receiving the downlink message, the MaaP of other nodes sends the circle of friends message to the friend user through 5MGC.

[0148] In a possible implementation of the present application, the communication method may also include: when the first 5GMC receives the fourth 5G message for sending a friend message sent by the first terminal, the first 5G message is sent to the first MaaP, and the fourth 5G message includes at least one of text, pictures, and videos; the first MaaP parses the fourth 5G message and determines that the fourth 5G message is a message sent to the first friend; the first MaaP sends information to obtain the first friend to the first 5GMC; when the first 5GMC receives the information for obtaining the first friend, it queries the number of the first friend and sends the number of the first friend to the first MaaP; the first MaaP uses the first message interaction encryption public key to encrypt the message sent to the first friend, and sends the encrypted message to the 5G message node where the terminal of the first friend is located.

[0149] That is to say, in addition to sending messages to the circle of friends through the first terminal and synchronizing them to all friends, the first user can also send messages to one or several other friends separately.

[0150] In one example, first, in response to the user selecting a button to send a message to a friend, the 5G message assembles the message to be sent and sends it to the 5GMC.

[0151] The first terminal receives an operation of the first user to open the friend system interface of the Chatbot of the 5G message application. The first terminal opens the friend system interface of the Chatbot. The friend system interface of the Chatbot receives content input by the first user to be sent to friends. The content can be in the format of text, picture, video, etc. The first terminal uplinks the circle of friends message to 5GMC1, and 5GMC1 sends the message to MaaP1.

[0152] Secondly, MaaP1 receives and identifies the uplink message sent by UE1 to the friend, and obtains the corresponding friend's interactive message public key T 公 , encrypt the message content and send it to the friend user.

[0153] The social messaging module of MaaP1 identifies the message as a message to friends, and sends a request to the node 5GMC1 where the initiator of the message is located to obtain the friend list of the user; after receiving the request, the social friend module of 5GMC1 queries the friend's number and sends it to MaaP1; after MaaP1 receives the friend's number of the user, it uses the T 公 After encryption, it is forwarded to the MaaP where the friend is located; after receiving the downlink message, the friend's MaaP sends the friend message to the friend user through 5MGC.

[0154] In a possible implementation of the present application, the communication method may also include: when the first 5GMC receives a request for querying a friend's personal information sent by the first terminal, determining whether the friend to be queried and the first terminal are in a friend relationship, the request for querying the friend's personal information adopts the general authentication mechanism GBA authentication, and the request for querying the friend's personal information includes querying the personal information and the message interaction encryption public key; when the first 5GMC determines that the friend to be queried and the first terminal are in a friend relationship, querying whether the personal information and the message interaction encryption public key of the friend to be queried are saved in the first 5GMC; when the personal information and the message interaction encryption public key of the friend to be queried are saved in the first 5GMC, the personal information and the message interaction encryption public key of the friend to be queried are sent to the first terminal.

[0155] In this embodiment, the first user can obtain the personal information and message interaction encryption public key of the friend user.

[0156] First, UE1 initiates a request to 5GMC to query the friend’s personal information and interactive encryption public key.

[0157] UE1's 5G message initiates an http request to 5GMC1 to query the user's friend's personal information. This http request uses GBA authentication.

[0158] Then, the social friend module of 5GMC verifies and authenticates the friend information query request, and responds to the social friend information and returns it to the UE. The request includes: user nickname, avatar, remarks, and the encrypted public key T for message interaction 公 .

[0159] The user social friend module of 5GMC1 verifies whether the first user (user 1) and the second user (user 2) are friends. If yes, the personal information module queries whether there is the personal information of user 2. The personal information module of 5GMC1 stores the personal information of user 2 and the encrypted public key T of the message interaction. 公 , then send the information to UE1.

[0160] In a possible implementation of the present application, the communication method may also include: when the personal information of the friend to be queried and the message interaction encryption public key are not saved in the first 5GMC, sending a request to query the friend's personal information to the 5G message node where the terminal of the friend to be queried is located; the first 5GMC receives the personal information of the friend to be queried and the message interaction encryption public key sent by the 5G message node where the terminal of the friend to be queried is located, and sends the personal information of the friend to be queried and the message interaction encryption public key to the first terminal.

[0161] That is to say, if the personal information module of 5GMC1 does not store the personal information of user 2 and the encrypted public key T for message interaction公 , then a request to query the personal information of user 2 is initiated to the node 5MGC2 where user 2 is located. 5GMC1 receives the personal information of the friend to be queried and the encrypted public key for message interaction sent by the 5GMC where the terminal of user 2 is located. The personal information module of 5GMC1 stores the personal information of user 2 and the encrypted public key T for message interaction. 公 , and send the information to UE1 at the same time.

[0162] Correspondingly, the social friend information module of the first terminal 5G message receives and saves the friend's personal information and the encrypted public key T public of the message interaction. UE1 refreshes the personal information of the friend in the 5G message and updates the contact book friend information.

[0163] In a possible implementation of the present application, the communication method may also include: the first 5GMC receives a personal information update request sent by the first terminal, the personal information update request adopts GBA authentication, the personal information update request includes updated personal information, and the updated personal information includes at least one of personal nickname, personal portrait, personal status, personal signature, and personal background; the first 5GMC updates and saves the updated personal information; the first 5GMC sends the updated personal information to the 5G message node where other terminals that have a friend relationship with the first terminal are located.

[0164] That is to say, the first terminal can also update personal information so that the user can freely show his or her information to other friends, such as current mood, interesting things, etc.

[0165] Specifically, the user opens the personal information editing interface of UE1's 5G message; the user edits personal information in the personal information editing interface of UE1's 5G message, including personal nickname, personal avatar, personal status, personal signature, personal background and other information. And the GBA authentication based on the sim card is used to send the http request to the personal information module of 5GMC1; the personal information module of 5GMC1 updates the user's personal information, and the information is synchronized to other 5MGC nodes to ensure information synchronization.

[0166] like Figure 3 As shown, it is a flow chart of a communication method provided by an embodiment of the present application. Figure 3 As shown, the communication method is applied to a 5G message node, which may be referred to as a second 5G message node below, and the communication method may include: the contents shown in S301 to S302.

[0167] In S301, a first 5G message sent by a 5G message node of a first terminal is received, and the first 5G message is sent to a second terminal.

[0168] In S302, a second 5G message sent by the second terminal is received, and according to the phone number of the first terminal contained in the second 5G message, the second 5G message is sent to the first terminal. The second 5G message is a 5G message returned by the second terminal agreeing to add a friend or a 5G message returned by the second terminal refusing to add a friend.

[0169] The second terminal UE2 receives and displays the message of adding a friend sent by the Chatbot's friend system. In response to the user 2 clicking the agree button, UE2 sends the message to the second 5G message node. Figure 4 As shown, the user can click an Agree button or a Reject button.

[0170] In an embodiment of the present application, the first 5G message sent by the 5G message node of the first terminal is first received, the first 5G message is sent to the second terminal, and then the second 5G message sent by the second terminal is received. According to the phone number of the first terminal contained in the second 5G message, the second 5G message is sent to the first terminal, and the second 5G message is a 5G message returned by the second terminal agreeing to add a friend or a 5G message returned by the second terminal refusing to add a friend. Based on the 5G message, the embodiment of the present application determines whether to add the friend based on the phone number of the first terminal, that is, communication can be carried out on the 5G message through the phone number. Since the phone number is real-name authenticated, the security problem of the user's real identity source is effectively solved.

[0171] In a possible implementation of the present application, a first 5G message sent by a 5G message node of a first terminal is received, and the first 5G message is sent to a second terminal according to the phone number of the second terminal contained in the first 5G message, including: receiving the first 5G message sent by the 5G message node of the first terminal; parsing the first 5G message, determining that the first 5G message is a social message for adding a friend, the first 5G message including a first message interaction encryption public key and the phone number of the first terminal; sending the first 5G message to the second terminal.
