Description

Method and apparatus for controlling user communication

The present invention relates to the field of communications and, more particularly, to a method and apparatus for controlling user communications. Background technique

In some networks, Session Initiation Protocol (SIP) is often used to control instant messaging such as video and voice. In the IP Multimedia Subsystem (IMS) network architecture, the Backbone User Agent (B2BUA, Back-to-Back User Agent) function is implemented through the Session Border Control (SBC). The existing SIP call signaling interaction process is that the calling user Caller sends an Invite message for the service request to the called user Callee, and the message carries the Caller's Media Description Session Description Protocol (SDP) information. The SDP information describes Caller's Media Internet Protocol (IP) address, port number, codec type, and transmission protocol. The Invite message is sent to the SBC, IMS core Core, and called side SBC on the calling side. Callee, if Callee is in the idle state, sends a User Ring 180 Ring message to the calling side. In the normal case, the media plane SDP information of Callee is carried in the 180 Ring message. After the 180 Ring message reaches the calling side, both the calling party and the called party, the SBC on both sides of the calling party, and the IMS Core know the media plane SDP information of the calling party and the called party. Then, Callee sends an off-hook response 200 OK message to the Caller. The IMS Core determines to start charging according to the 200 OK message. After the Callee receives the acknowledgement ACK response message sent by the Caller, the call service establishment of the calling party and the called party is completed.

However, according to the protocol architecture of IMS, the media message does not pass through the IMS Core, but the B2BUA made by the SBC. Since the media plane channel has been established after the SBC learns the media information of the calling party, some illegal users are likely to use the early media interworking ability of the SIP protocol to realize the pirate call to reach a service call without paying. .

Therefore, an appropriate method is needed to prevent the calling and called users from utilizing the ability of early media intercommunication before the system to charge to achieve the purpose of normal communication without being billed, thereby reducing the economic loss of the telecommunication operator and reducing the network security risk. Summary of the invention

1 shows a schematic flow chart of a method of controlling user communication according to an embodiment of the present invention as described from the perspective of the called side SBC. As shown in Figure 1, the method includes:

S110, receiving a first message that is sent by the called user to the calling user, including the first called user information, where the first called user information is used to establish a communication connection between the calling user and the called user; S120, According to the first message, the communication between the calling user and the called user is prohibited; S130, receiving a charging confirmation message sent by the called user to the calling user;

S140. Allow communication between the calling user and the called user according to the charging confirmation message. Specifically, in S110, the called side SBC may obtain the calling user information (including the media IP address, port number, codec type, transmission protocol, etc. of the calling user) according to the Invite message sent by the calling user, and After receiving the Invite message sent by the calling user, the called user may send a first message (eg, 180 ring message, 18X message, etc.) including the called user information (eg, SDP information) to the called side SBC, the called side. The SBC may obtain the called user information (including the media IP address, port number, codec type, and transmission protocol of the called user) according to the first message, so that the called side SBC can be based on the called user information and the calling party. The user information establishes a media plane channel with the calling side SBC. At this time, the called user can already send the media message to the calling user, and the called side SBC can also forward the first message to the calling party via the IMS Core, the calling side SBC, after receiving the first message. The user, so that the calling side SBC obtains the called user information (including the media IP address, port number, codec type, and transmission protocol of the called user), thereby implementing B2BUA. Therefore, at S120, the called side SBC may prohibit communication between the calling user and the called user according to the first message. In this embodiment, the communication between the calling user and the called user may be prohibited in various manners, for example, media messages that are exchanged between the calling user and the called user are not blocked, and the calling user is not sent to the calling user. Calling user information (for example, SDP information) or sending the specified information to the calling user so that the calling user cannot obtain the media IP address, port number, codec type, and transmission protocol of the called user, so as to prevent the calling user. Implement B2BUA with the called user. The above method of prohibiting communication between the calling user and the called user will be described in detail below.

At S130, the called side SBC may receive a charging confirmation message (for example, a 200 OK message) sent by the called user to the calling user, and forward the 200 OK message to the IMS Core to enable the system to charge.

At S140, the called side SBC may determine, according to the charging confirmation message, that the system starts charging, thereby allowing communication between the calling user and the called user, where communication between the calling user and the called user is allowed. The operation corresponds to the manner in which communication between the calling user and the called user is prohibited, which will be described in detail below.

In this way, the method for controlling user communication according to the embodiment of the present invention controls communication between the calling user and the called user according to the first message and the charging confirmation message sent by the called user including the user information of the called user. The main called party is prohibited from communicating normally before the system is charged, thereby preventing the main called party from utilizing the early media interworking capability before the system is charged, so as to achieve the purpose of normal communication without being charged, thereby reducing the telecommunication operator. Economic loss, reducing cybersecurity risks.

Next, a method of prohibiting communication between the calling user and the called user and a method corresponding to the communication between the calling and called users will be described with reference to Figs. 2 to 4 .

In the embodiment of the present invention, after the calling side SBC establishes a communication connection with the called side SBC to implement the B2BUA, the called side SBC shields the called user from sending the first call to the calling user before receiving the charging confirmation message. The media message and/or the second media message sent by the calling user to the called user is used to prohibit the main called user from communicating normally before the system charges. Moreover, the called side SBC may block the media message sent by the called user to the calling user after receiving the first message, or may forward the first message to the calling side SBC via the IMS Core. Caller User, so that the calling side SBC obtains the called user information (including the media IP address, port number, codec type, and transmission protocol of the called user), thereby implementing B2BUA, and media messages from both the calling and the called users. Shield. Therefore, the method further includes:

The first message is forwarded to the calling user.

According to the first message, the communication between the calling user and the called user is prohibited, including: receiving a first media message sent by the called user to the calling user, and sending the called user to the called party User's second media message;

And masking, according to the first message, at least one of the first media message and the second media message, and

The communication between the calling user and the called user is allowed to include:

The media message is forwarded to the calling user and/or the called user.

Specifically, as shown in FIG. 2, at S210, the called side SBC can obtain the calling user information according to the Invite message sent by the calling user (including the media IP address, port number, codec type, and transmission of the calling user). Protocol, etc.), and the called user can send a first message including the called user information (for example, SDP information) to the called side SBC after receiving the Invite message sent by the calling user (for example, 180ring message, 18X message) The called side SBC can obtain the called user information (including the media IP address, port number, codec type and transmission protocol of the called user, etc.) according to the first message, so that the called side SBC can be based on the called The user information and the calling party information are combined with the calling side SBC to establish a media plane channel.

At this time, the called user can send a media message to the calling user. In S230, the called side SBC receives the first media message sent by the called user, and in S240, the called side SBC can send the called party to the called user. Block the media message of the calling user.

Optionally, the called side SBC may further forward the first message to the calling user via the IMS Core, the calling side SBC, after receiving the first message, so that the calling side SBC obtains the called user information (including The called user's media IP address, port number, codec type, and transport protocol, etc., thereby implementing B2BUA. At this time, the SBC called the SBC can receive the first media message sent by the called user and the second media message sent by the calling user to the called user. At S240, the called side SBC may block the first media message sent by the called user to the calling user and the second media message sent by the calling user to the called user. Thereby, it is possible to prohibit the main called party from communicating normally.

At S250, after receiving the charging confirmation message (for example, 200 OK message) sent by the called user, the called side SBC may determine that the system starts charging, and forwards the called user to the S260. The first media message of the calling user and the second media message sent by the calling user to the called user allow the calling party and the called user to communicate normally.

In this way, the method for controlling user communication according to the embodiment of the present invention controls communication between the calling user and the called user according to the first message and the charging confirmation message sent by the called user including the user information of the called user. The main called party is prohibited from communicating normally before the system is charged, thereby preventing the main called party from utilizing the early media interworking capability before the system is charged, so as to achieve the purpose of normal communication without being charged, thereby reducing the telecommunication operator. Economic loss, reducing cybersecurity risks. Moreover, since the media message from both the calling party and the called party can be shielded, the control effect can be improved.

It should be understood that, in the above embodiment, the method for controlling user communication is described by taking the called side SBC as an example, but the present invention is not limited thereto, and the other can forward and block between the calling user and the called user. The network elements of the interactive media message are all within the protection scope of the present invention. For example, the calling side SCB can also be used to block the media message. However, considering the need to use the media channel of the calling side SBC to the calling user. For the playback service, such as the multimedia CRBT service, it is preferable to use the called side SBC to block the media message.

In the embodiment of the present invention, the manner in which the calling side SBC and the called side SBC are prohibited from establishing a media plane is also prohibited to prohibit the main called party from communicating normally. Therefore, the prohibition of communication between the calling user and the called user includes:

Block the first message, and

The first message is forwarded to the calling user.

Specifically, as shown in FIG. 3, at S310, the called side SBC can obtain the calling user information (including the media IP address, port number, codec type, and transmission of the calling user according to the Invite message sent by the calling user. Protocol, etc.), and the called user can send a first message including the called user information (for example, SDP information) to the called side SBC after receiving the Invite message sent by the calling user (for example, 180ring message, 18X message) The called side SBC can obtain the called user information (including the media IP address, port number, codec type and transmission protocol of the called user, etc.) according to the first message, so that the called side SBC can be based on the called The called user information and the calling user information establish a media plane channel with the calling side SBC, and the called user can already send the media message to the calling user. At this time, the calling side SBC cannot obtain the media IP address, port number, codec type, and transmission protocol of the called user by not transmitting the message including the called user information to the calling side SBC, thereby The calling user cannot send media messages to the called user. The purpose of prohibiting the normal communication of the calling and called users is achieved. Therefore, at S320, the called side SBC may mask the first message (eg, 180 ring message, 18X message, etc.) including the called user information. At S330, after receiving the charging confirmation message (for example, 200 OK message) sent by the called user, the called side SBC may determine that the system starts charging, and forwards the first message to the calling user at S340, The calling side SBC obtains the called user information (including the media IP address, port number, codec type, and transmission protocol of the called user), so that the calling side SBC and the called side SBC establish a media plane channel to implement the main Call the user and the called user for normal communication.

In the embodiment of the present invention, the called side SBC may also send the specified information to the calling side SBC to replace the called user information according to the interaction mechanism of the SDP, so as to prohibit the calling side SBC and the called side SBC from establishing a media plane channel. Therefore, the prohibiting communication between the calling user and the called user includes: sending a second message including the second called user information to the calling user, the second called user information is used to prohibit the calling party The user establishes a communication connection with the called user, and

A third message including the first called user information is sent to the calling user.

For example, according to the interaction mechanism of the SDP, when the c-line address (the called user IP address) of the called user's SDP information is all 0s, the calling user cannot send the media "3⁄4 text" to the called user. Therefore, the direction The second message that the calling user sends the second called user information includes:

Modifying the first parameter included in the first called user information to generate the second called user information;

Sending a second message including the second called user information to the calling user.

Specifically, as shown in FIG. 4, at S410, the called side SBC can obtain the calling user information (including the media IP address, port number, codec type, and transmission of the calling user according to the Invite message sent by the calling user. Protocol, etc.), and the called user can send a first message including the called user information (for example, SDP information) to the called side SBC after receiving the Invite message sent by the calling user (for example, 180ring message, 18X message) And so on, the called side SBC can obtain the called user information according to the first message (including the media IP address, port number, codec of the called user) The type and the transmission protocol, etc., so that the called side SBC can establish a media plane channel with the calling side SBC according to the called user information and the calling party information, and the called user can already send the media message to the calling user. At this time, in S420, the called side SBC may generate the first information by replacing the first called user information in the first message (for example, 180ring message, 18X message, etc.) with the specified second called user information according to the SDP interaction mechanism. Two messages (for example, 180 ring message, 18X message, etc.), and send the second message to the calling side SBC, so that the calling side SBC cannot obtain the media IP address, port number, codec type or transmission protocol of the called user, etc. At least one of the correct parameters, so that the calling user cannot send the media message to the called user, so as to prohibit the main called user from communicating normally. At S430, after receiving the charging confirmation message (for example, 200 OK message) sent by the called user, the called side SBC may determine that the system starts charging, and in S440, send the first called user information to the calling user. a third message (for example, a 200 OK message), so that the calling side SBC obtains the called user information (including the media IP address, port number, codec type, transmission protocol, etc. of the called user), thereby making the calling side SBC Establish a media plane channel with the called side SBC to implement normal communication between the calling user and the called user.

Moreover, according to the interaction mechanism of the SDP, when the c-line address (the called user IP address) of the called user's SDP information is all 0, the calling user cannot send the media "3⁄4 text" to the called user. Therefore, at S420 It is also possible to modify the c-line address parameter (eg, modify the IP address to 0.0.0.0) in the first message (eg, 180ring message, 18X message, etc.) to generate the second called user information. After the charging confirmation message, the first called user information may be directly carried in the charging confirmation message and sent to the calling side SBC.

It should be understood that, in the foregoing embodiment, the method for controlling user communication is described by taking the called side SBC as an example, but the present invention is not limited thereto, and the other can forward, block, or modify the calling party and the calling user. The network elements including the called user information that are exchanged between the called users are all within the protection scope of the present invention.

5 is an interaction diagram of a method for controlling user communication according to an embodiment of the present invention. Referring to FIG. 5, a 180ring message is used as a first message, and a 200 OK message is used as a charging confirmation message. The SDP information of the called user is used as the called user information to describe the complete interaction process. As shown in FIG. 5, in S501 S508, the calling user sends an Invite message (ie, a request message) to the calling side SBC, where the message carries the calling user SDP information, and in the SDP information, the media on the calling side is carried. Parameters such as IP address, port number, codec type, and transport protocol. Since the SBC implements the B2BUA function in the IMS network architecture, the SBC on the calling side needs to reply the temporary response message to the calling user, and simultaneously deliver the Invite message to the IMS Core. The IMS Core forwards the Invite message to the SBC where the called user is located, and finally the called user receives the Invite message of the calling user. At S509, if the called user is in the idle state, the 180 ring message, that is, the ringing message, is sent to the calling user via the called side SBC. In the normal case, the SDP information of the called user is carried in the 180 Ring message. At this time, the SBC on the called side knows the media plane SDP information of the calling party and the called party has been able to send the called party to the calling user. Media message. Therefore, at S510, the calling side SBC prohibits user communication.

Optionally, the called side SBC may forward the 180 Ring message to the calling user, so that after the called 180 Ring message reaches the calling user, both the calling and called users, the SBC and the IMS on both sides of the calling party and the called party The Core can obtain the media surface SDP information of the calling party and the called party. According to the protocol architecture of the IMS, the media stream does not pass through the IMS Core, but the B2BUA of the media plane is made by the SBC, that is, the SBC is a bridge for the media stream communication of the UE. At this time, although the response of the called side user has not been received, 200 OK. Message, since the SBC has already learned the media face information of the calling party and the media face channel has been established, the called side SBC can block the media messages from both the calling party and the called party.

Optionally, the called side SBC may also not send the 180 Ring message to the calling user, so that the calling user cannot obtain the SDP information of the called user, thereby preventing the establishment of the media plane channel.

Optionally, the called side SBC may also modify the c-line IP address in the SDP message in the 180 Ring message to 0.0.0.0, so that according to the SDP interaction mechanism, the calling user cannot send the media message to the called user. .

At S511, the called side SBC receives the 200 OK message sent by the called user, and can determine that the system starts charging.

Optionally, the called side SBC can forward the media message from both the calling party and the called party.

Optionally, the called side SBC may also send the 180 Ring message to the calling user, so that the calling user can obtain the SDP information of the called user, thereby allowing the establishment of the media plane channel.

Optionally, the called side SBC may also send the IP address 7 of the called user to the 200 OK message and send it to the calling user, thereby allowing the establishment of the media plane channel. At S513~S515, the 200 OK message is forwarded to the calling user via the IMS Core and the calling side SBC.

In S516~S519, after the calling user receives the 200 OK of the called user, and the called user receives the ACK response message of the calling user, the calling service of the calling party is established normally.

In the embodiment of the present invention, the first parameter is described by using the IP address of the called user as an example. However, the present invention is not limited thereto. For example, the port information in the SDP information may also be modified. Moreover, the first user information is described by the session representation protocol SDP information, but the present invention is not limited thereto, and other information that can be used to establish a communication connection (media plane channel) falls within the protection scope of the present invention. In the embodiment of the present invention, the first message is described by taking the ringing 180Ring message and the temporary response 18X message as an example, but the present invention is not limited thereto, and other messages capable of carrying information such as SDP and sent before 200 OK are used. All fall within the scope of protection of the present invention. Further, the 200 OK message is taken as an example. The charging confirmation message includes a 200 OK message. However, the present invention is not limited thereto, and other messages capable of determining that the system starts charging are included in the scope of the present invention.

Hereinabove, a method of controlling user communication according to an embodiment of the present invention is described in detail with reference to Figs. 1 through 5, and an apparatus for controlling user communication according to an embodiment of the present invention will be described in detail below with reference to Fig. 6.
