RTP (Reliable Transport Protocol): a protocol for managing the transmission and reception of EIGRP packets.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Example 1

In this embodiment, a method for processing a call service of VOIP is provided, and fig. 1 is a flowchart of a method for processing a call service of VOIP according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:

step S102, obtaining a Session Initiation Protocol (SIP) data packet meeting a preset rule from a Voice Over Internet Protocol (VOIP) call service;

step S104, analyzing a session description protocol SDP message from the SIP data packet;

step S106, sending data corresponding to the media type of the SDP message to the IPTV.

Through the steps from S102 to S106, the session initiation protocol SIP data packet meeting the preset rule is obtained from the VOIP call service, the session description protocol SDP message is analyzed from the SIP data packet, and the data corresponding to the media type of the SDP message is sent to the IPTV, so that the VOIP call service can be carried out while watching TV, the problem that a mode of combining the VoIP technology with other equipment does not exist in the related technology is solved, and the effect of improving the user experience is achieved.

In an alternative embodiment of the present application, the manner of sending the data corresponding to the media type of the SDP message to the IPTV of the present application, which is referred to in step S106, may be implemented as follows:

step S106-11, under the condition that only the media information of voice type exists in the SDP message, the calling information or the called information corresponding to the SIP data packet is sent to IPTV to be displayed;

step S106-12, under the condition that the SDP message comprises the media information of the video type, the RTP packet of the reliable transmission protocol is mirrored to the IPTV so as to realize the video call.

It can be seen that, in the step S106, when only the media information of the voice type (AUDIO) is in the SDP, only the calling information or the called information needs to be displayed in the IPTV; when media information of VIDEO type (VIDEO) is contained in the SDP, the RTP packet needs to be mirrored to the IPTV.

Furthermore, in another alternative embodiment of the present application, data corresponding to the media type of the SDP message may be sent to the IPTV by:

step S11, creating a thread for reporting IP data packet, and establishing connection in appointed time;

step S12, copying the IP data packet and adding the IP data packet into a buffer chain table;

step S13, the thread is awakened to read the data packet in the buffer linked list to send IPTV.

For the above steps S11 to S13, a thread for reporting IP packets is created first, and a timer is started to establish a stable connection within a specified time for packet sending; secondly, after receiving the IP data packets matched with the rules, copying the IP data packets out and adding the IP data packets into a cache linked list; and finally, awakening the reporting thread, reading the cache linked list and sending the packet in the linked list to the IPTV.

In another optional embodiment of the present application, the manner of acquiring the SIP packet that satisfies the preset rule in step S102 of the present application may be:

step S102-11, adding a preset rule into a matching rule linked list;

step S102-12, monitoring the received and transmitted data packet based on the rule linked list;

and step S102-13, stripping the Ethernet head of the received and transmitted data packet, and taking out the IP information and the port information to screen out the SIP data packet which accords with the preset rule.

In yet another alternative embodiment of the present application, the method in the present application further comprises:

step S108, number information sent by the IPTV terminal in a dial-up mode is acquired;

and step S110, packaging the number information into an SIP data packet according to the IP information and the port information of the preset rule.

For the above step S108 and step S110, when dialing is performed at the IPTV terminal, according to the original packet receiving and sending path, the IPTV will send the number to the gateway and report the message of the key, the gateway receives the message, extracts the number, encapsulates the number into the SIP protocol packet according to the IP address and port of the configuration rule, and sends the SIP protocol packet to the voice server, and the subsequent implementation is performed according to the existing VoIP protocol of the gateway.

The present application will be illustrated with reference to specific embodiments thereof;

the specific implementation mode is that based on the existing VoIP technology, the network architecture and the existing network environment of the existing operator are utilized to realize the visual VOIP conversation combining the voice of the ONU and the IPTV. According to the specific implementation mode of the application, when the ONU terminal sends or receives a voice service request, the request information is displayed on an IPTV display, such as an incoming call number, a calling number, a user name and the like, and if a video call service exists, a video call can be carried out on the IPTV. And secondly, the layout of hanging a telephone call under the traditional home gateway is eliminated, and the user can dial at the IPTV terminal to realize the telephone function.

The present embodiment provides a structural block diagram of interaction between a VoIP device and an IPTV device, as shown in fig. 2, the structural block diagram includes: the device comprises a VoIP management module, a kernel protocol stack module, a packet receiving and transmitting module and a function module.

The VoIP management module defines elements required by the rule, and the elements are sent to the IPTV only if the elements of the protocol packet and the data packet all meet the rule, and the interactive structure of the VoIP and the IPTV equipment sends the elements to the kernel protocol stack module;

the kernel protocol stack module is used for formulating specific rules, configuring the rules to a kernel and monitoring the packet receiving and transmitting module;

the receiving and sending module is used for receiving and sending protocol packets and data packets in the scheme, rules of the kernel protocol stack module can be embedded in the module, and once the conditions are met, the module can be sent to the function module for processing;

the functional module is used for processing the packet meeting the rule, reading the quintuple information and the individual information in the SDP packet if the packet is a protocol packet, reassembling and splicing the quintuple information and the individual information, and sending the information to a specified position; if the data packet is the data packet, only address conversion is needed according to the type of the packet, and the data packet is sent to a specified position.

Based on the above structure of interaction between VoIP and IPTV devices in fig. 2, the way of implementing the visual VoIP call combining the voice of ONU and IPTV in this embodiment includes three stages: preparing interface, configuring rule and processing data packet.

In the interface preparation stage, the display specification of the IPTV needs to be known first, and the type of the data packet identified and displayed by the IPTV needs to be known; and interfaces and message formats corresponding to the IPTV, such as event codes representing states of off-hook, on-hook, dial-up, etc., so that the gateway side can perform adaptation.

Based on this, the method step of preparing the interface stage includes:

step S1, the VoIP management module provides rule parameters, including the port number of the INVITE message in the protocol packet and the negotiated port number and IP address in the SDP packet, when the VoIP process starts working, it will read the value of the current parameter from the user configuration and send it to the kernel protocol module;

step S2, the kernel protocol module formulates specific rules that these parameters need to satisfy, and adds the rules into the matching rule linked list, and constantly monitors the packet receiving and transmitting module, strips off the ethernet header, takes out the IP information and the port information, screens out the SIP packet that meets the rules, then parses out the SDP (session description protocol) information in the SIP packet, and performs different processing according to the difference of the SDP, as shown in fig. 3:

first, when only media information of voice type (AUDIO) is in the SDP, only the calling information or the called information needs to be displayed in the IPTV.

Secondly, when media information of VIDEO type (VIDEO) is contained in the SDP, the RTP packet needs to be mirrored to the IPTV.

In step S4, the function module processes the screened packets and extracts the IP data packets from the screened packets.

Specifically, the functional module creates a thread for reporting an IP data packet, starts a timer, and establishes a stable connection within a specified time to perform a packet sending operation; after receiving the IP data packets matched with the rules, the functional module copies the IP data packets out and adds the IP data packets into a cache linked list; and finally, awakening the reporting thread, reading the cache linked list and sending the packet in the linked list to the IPTV.

Step S5, when dialing at IPTV terminal, IPTV sends the number to the gateway according to the original route of the receiving and sending packets, and reports the message of the key, the gateway receives the message and then extracts the number, and encapsulates the number into SIP protocol packet according to the IP address and port of the configuration rule, and sends the SIP protocol packet to the voice server, and the realization in the next step is according to the existing VoIP protocol of the gateway.

Through the specific implementation mode, the user can be more humanized, the user does not miss the call when watching the television, the user experience is improved, and the VoIP service has the characteristics of high efficiency, real-time performance and diversity; the operator can attract more users by using the technology, and the users can have brand new experience different from the traditional telephone service when enjoying the benefits brought by the network, thereby generating corresponding commercial benefits.
