After further analysis, the inventor finds that an emerging media service can be implemented by using an Internet Protocol Multimedia Subsystem (IMS) network capable of supporting Multimedia services. However, since the IMS network cannot recognize the private media protocol, the IMS network rejects the service request of the emerging media, which results in failure to successfully carry the emerging media service through the IMS network. The inventor realizes the support of emerging media services by enhancing the function of the IMS network access equipment. An embodiment of the multimedia communication method of the present invention is described below with reference to fig. 1.
Fig. 1 is a flow diagram of a multimedia communication method according to some embodiments of the invention. As shown in fig. 1, the multimedia communication method of this embodiment includes steps S102 to S108.
In step S102, the IMS network access device obtains a media service request of the sending terminal, where the media service request carries media type information.
In some embodiments, the IMS network Access device is a Border Access Controller (BAC). In some networks, the BAC may be located in the same device as the P-CSCF (Proxy Call Session Control Function), so that the IMS network access device may be a P-CSCF/BAC device.
In some embodiments, the media service request is an invite request based on a Session Initiation Protocol (SIP) Protocol.
In step S104, the IMS network access device searches the pre-stored private media type information for the media type information carried in the media service request.
The processing of the common audio/video Session Description Protocol (SDP for short) (3GPP TS 24.229 Protocol) specifies known common audio/video media, such as media encoded using Adaptive Multi-Rate (AMR), h.264, and so on. The private media type information is media type information corresponding to media based on a private protocol, and may also be referred to as an emerging media type. For example, the media types may be holographic, virtual reality, augmented reality, and the like, besides normal audio and video.
In step S106, in response to the media type information carried in the media service request being searched in the pre-stored private media type information, the IMS network access device adds a preset private media type identifier to the media type information.
In some embodiments, the Media type information includes information in a field m and an encoding attribute field (rtpmap in Attributes) in a Media Description (Media Description) in the invite request. For example, the relevant content in the invite request corresponding to the common audio media type may be exemplarily as follows:
m＝audio 3456RTP/AVP 97 96
b＝AS:25.4
a＝curr:qos local none
a＝curr:qos remote none
a＝des:qos mandatory local sendrecv
a＝des:qos none remote sendrecv
a＝rtpmap:97AMR
a＝fmtp:97mode-set＝0,2,5,7；mode-change-period＝2
a＝rtpmap:96telephone-event
a＝maxptime:20
the field m indicates a media type, where the media information "audio 3456RTP/AVP 9796" indicates an audio media type, AMR in "a ═ RTP map:97 AMR" is a specific codec of the media type, and "audio" and "AMR" may be used together as the media type information. When the IMS network access device detects the media type information, the IMS network access device carries out ordinary forwarding processing on the request.
When the media service request is based on an emerging media service, the relevant content in the invite request may be exemplarily as follows:
m＝VR video 3400RTP/AVP 98 99
b＝AS:75
a＝curr:qos local none
a＝curr:qos remote none
a＝des:qos mandatory local sendrecv
a＝des:qos none remote sendrecv
a＝rtpmap:98VRcode1
a＝fmtp:98profile-level-id＝0
a＝rtpmap:99MP4V-ES
the media type information includes "VR video" as the media type and a specific codec mode "VRcode 1", which is a type other than the existing standard and cannot be recognized by a general IMS access device. In the embodiment of the present invention, when the IMS network access device searches for content matching the media type "VR video" and the media codec mode "VRcode 1" in the pre-stored private media type information, the private media type identifier "newtype" may be added to the m field. The processed m fields are as follows:
m＝newtype VR video 3400RTP/AVP 98 99
thus, when other devices in the IMS network detect the "newtype" identification in the media type information, it can be determined that the request is a request allowed by the IMS network.
In some embodiments, in response to searching for the media type information carried in the media service request in the pre-stored private media type information, and that the user identifier of the sending terminal and the user identifier of the receiving terminal belong to pre-configured user identifiers, the IMS network access device adds a preset private media type identifier to the media service request. Therefore, whether the users of the sending terminal and the receiving terminal are configured emerging media users or not can be detected, so that the private media type identification is added under the condition that the users of the sending terminal and the receiving terminal are both configured emerging media users and the media type is a preset emerging media.
In step S108, the IMS network access device sends the media service request to other devices in the IMS network, so that the other devices send the media service request to the receiving terminal according to the private media type identifier.
In some embodiments, in response to detecting that a media service request sent by another device in the IMS network has a private media type identifier, the IMS network access device of the receiving terminal deletes the private media type identifier, and sends the media service request to a corresponding terminal, that is, the receiving terminal. Therefore, the multimedia communication between the sending terminal and the receiving terminal can realize end-to-end transmission, and the content sent by the sending terminal and the content received by the receiving terminal are kept consistent.
Currently, when a device in an IMS network detects private media type information, a rejection process is performed on a media service request. After the private media type identifier is added to the media type information, other devices in the IMS network may perform non-rejection processing on the corresponding request after detecting the private media type identifier, regardless of the media service carried in the communication process, for example, may pass the request through, or perform service processing as needed, and then forward the request. Thus, the receiving terminal can obtain the media service request based on the emerging media sent by the sending terminal.
By the method of the embodiment, the invention can add the private media type identifier to the media service request corresponding to the preset private media type through the IMS network access device, so that other devices in the IMS network can realize the transmission of the media service request by identifying the private media type identifier. Thus, emerging media services can be implemented based on IMS networks.
In some embodiments, the information of the emerging media subscribers may be pre-configured in a Home Subscriber Server (HSS). The IMS network access device may query from the HSS. An embodiment of the multimedia communication method of the present invention is described below with reference to fig. 2.
Fig. 2 is a flow chart illustrating a multimedia communication method according to further embodiments of the present invention. As shown in fig. 2, the multimedia communication method of this embodiment includes steps S202 to S210.
In step S202, the IMS network access device obtains a media service request of the sending terminal, where the media service request carries media type information.
In step S204, the IMS network access device searches the pre-stored private media type information for the media type information carried in the media service request, where the private media type information is the media type information corresponding to the media based on the private protocol.
In step S206, the IMS network access device sends a user query request to the HSS, where the user query request includes the user identifier of the sending terminal and the user identifier of the receiving terminal, so as to determine whether the user identifier of the sending terminal and the user identifier of the receiving terminal belong to the pre-configured user identifiers according to the query result of the HSS.
In step S208, in response to that the media type information carried in the media service request is searched in the pre-stored private media type information, and the user identifier of the sending terminal and the user identifier of the receiving terminal belong to the pre-configured user identifier, the IMS network access device adds the preset private media type identifier to the media service request.
In step S210, the IMS network access device sends the media service request to other devices in the IMS network, so that the other devices send the media service request to the receiving terminal according to the private media type identifier.
By the method of the embodiment, the user identification of the pre-configured emerging media user can be stored in the HSS. The IMS network can obtain authentication information of the receiving terminal and the transmitting terminal by communicating with the HSS. Therefore, the service request corresponding to the pre-configured user and media type can be transmitted.
An embodiment in which each network element in the IMS network carries an emerging media service is described below with an IMS network access device being a P-CSCF/BAC as an example.
Fig. 3 is a flow chart illustrating a multimedia communication method according to some embodiments of the present invention. As shown in fig. 3, the multimedia communication method of this embodiment includes steps S302 to S318.
In step S302, the P-CSCF/BAC1 pre-configures information related to the newTypeA of private media type agreed with the emerging media terminal a. The P-CSCF/BAC1 is an IMS network access device on the A side of the emerging media terminal.
In step S304, the HSS pre-configures the user identities of the new media terminal a and the new media terminal B.
In step S306, the emerging media terminal a initiates a media service request to the emerging media terminal B, where the media service request includes media type information corresponding to newTypeA.
In step S308, the P-CSCF/BAC1 searches the pre-configured content for media type information corresponding to newTypeA.
In step S310, the P-CSCF/BAC1 queries the HSS whether the emerging media terminal a and the emerging media terminal B are pre-configured emerging media users in response to the search for the media type information corresponding to newTypeA.
In step S312, the P-CSCF/BAC1 adds a preset "newType" identifier to the media type information in response to obtaining the query result that the emerging media terminal a and the emerging media terminal B are pre-configured emerging media users.
In step S314, the P-CSCF/BAC1 transmits the media service request to the next hop device in the IMS network, and the S-CSCF1, AS1, I-CSCF, and S-CSCF2 in the IMS network forwards the media service request according to the newType identifier.
In step S316, the IMS network access device P-CSCF/BAC2 on the B side of the emerging media terminal deletes the newType identifier.
In step S318, the P-CSCF/BAC2 sends the media service request to the emerging media terminal B.
