In the IMS call process, the call parties forward the voice information of the two parties through the network equipment. The voice information sent by the calling party to the calling party firstly reaches the network equipment, and then the network equipment forwards the voice information to the communication party.
It should be noted that there may be a plurality of network devices between two parties of a call over the IMS communication link.
In one embodiment of the application, a PC can be added between the electronic equipment and the network, and the PC routes and forwards the voice packet, so that the interactive information between the electronic equipment and the network can be received on the PC; when the electronic equipment is in communication, the PC receives a voice packet sent to the electronic equipment by the network, acquires information in the voice packet and intercepts the voice packet so that the voice packet cannot be sent to the electronic equipment, and then sends a designated voice packet (abnormal voice packet) prepared in advance to the electronic equipment through the PC to observe the playing voice quality of the electronic equipment.
In the embodiment of the application, a router can be added on a link between the network equipment and the receiver on the IMS communication link, after the voice information sent to the receiver by the sender arrives at the network equipment, the network equipment sends the voice information to the router, and the router does not forward the voice information, but sends preset voice information to the receiver, wherein the preset voice information is abnormal voice information.
In one example, the abnormal voice information may be abnormal voice information with data messages in a disordered order. For example, the voice information including message 1, message 2 and message 3 is correctly sequenced as message 1, message 2 and message 3, if the message in the voice information is sequenced as message 3, message 1 and message 2, the voice information is the abnormal voice information with disordered data message sequence.
In another example, the abnormal voice information may be abnormal voice information in which a data packet is missing. Still take the above-mentioned voice information including message 1, message 2, message 3 and correct message ordering as message 1, message 2 and message 3 as an example, if only message 1 and message 3 are included in the voice information and no message 2 is included in the voice information, the voice information is the abnormal voice information of the missing data message.
Fig. 3 is a schematic call process diagram in an IMS call voice quality testing method according to an embodiment of the present application. Referring to fig. 3, in this embodiment, both parties of the call follow protocols such as SIP (Session initialization Protocol, session initiation protocol), UDP (UserDatagram Protocol ), TCP (Transmission Control Protocol, transmission control protocol), IP (Internet Protocol ), and the like.
With continued reference to fig. 3, in this embodiment, both parties of the call access the network through a fixed broadband network and an LTE (Long Term Evolution ) network, respectively, and signaling of both parties is transmitted through a path indicated by a dashed line with a double-headed arrow in fig. 3.
The library stores abnormal voice information, and the abnormal voice information is encapsulated by a UDP protocol, an IP protocol, an RTP (Real-time transport protocol), an RTCP (Realtime Transport Control Protocol, a transmission control message protocol), etc., to form a data packet of the abnormal voice information, and the data packet is transmitted to a receiving party (i.e., a smart phone in fig. 3) through a P-GW (Packet data network GateWay, a packet data network GateWay), an S-GW (Serving GateWay), and an LTE network.
CSCF (Call Session Control Function ) device is a functional entity inside the IMS, which is the core of the whole IMS network. The CSCF device is mainly responsible for handling signalling control during a multimedia call session. It manages user authentication of IMS network, qoS of IMS bearing surface, control of SIP session in cooperation with other network entities, service negotiation, resource allocation, etc. In fig. 3, the device labeled S-CSCF (Serving-CSCF)/I-CSCF (inter-call-session control function)/MRFC (Multimedia Resource Function Controller, multimedia resource controller)/BGCF (Breakout Gateway Control Function, egress gateway control function) is the core device of the IMS call network.
Fig. 4 is a schematic diagram illustrating the implementation principle of a call procedure in the IMS call voice quality testing method according to the embodiment of the application. Referring to fig. 4, in this embodiment, an SBC (Session Border Controller )/P-CSCF (Proxy-CSCF, proxy call session control function) device is a core device of the IMS call network. After the device (for example, smart phone) performing IMS call establishes communication connection through the SBC/P-CSCF device (as shown by the dotted line in fig. 4, the receiver of voice is connected to the SBC/P-CSCF device through the S-GW device and the P-GW device), the SBC/P-CSCF device sends the voice packet sent by the sender to the receiver to the P-GW device, the P-GW device sends the voice packet to the PC, the PC intercepts the voice packet, reads an abnormal voice packet from the report library, and transmits the abnormal voice packet to the receiver through the S-GW device and the like. Therefore, the receiver receives the abnormal voice packet, realizes the control of the voice packet received by the receiver, and further can test whether the receiver can normally play after receiving the abnormal voice packet.
