Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, interfaces, techniques, etc. in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
For the purpose of understanding the present application, a communication system of the present application will be described.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of a communication system of the present application, and fig. 2 is a flowchart of a communication method of the communication system shown in fig. 1 of the present application. Taking an LTE trunking private network as an example, the communication system 10 is an LTE broadband trunking communication system, and includes a first mobile terminal 11, a second mobile terminal 12, a plurality of base stations 13, 14, and a trunking core network 15. The mobile terminals 11 and 12 are connected to a cluster core network 15 through base stations 13 and 14, and the cluster core network 15 is used for mobility management and call management. The first mobile terminal 11 and the second mobile terminal 12 can perform multimedia communication, such as video call, etc., between the base station and the cluster core network.
As shown in fig. 2, the multimedia communication process of the communication system 10 is as follows:
1. and (3) call establishment process: when the first mobile terminal 11 sends a call request through the base station 13, the trunking core network 15 receives the call request and forwards the call request to the called second mobile terminal 12 through the base station 14 according to the call request, and when the second mobile terminal 12 sends an answer message of the call request, a call service is established.
Wherein, in the process, the first mobile terminal 11 and the second mobile terminal 12 may perform negotiation of multimedia parameters first.
Referring to fig. 3, after the first mobile station 11 and the base station 13 perform context establishment, the first mobile station 11 serving as a main calling end initiates a CALL REQUEST (CALL REQUEST), where the CALL REQUEST includes multimedia parameter information of a negotiated Session Description Protocol (SDP), and may specifically include multiple sets of multimedia parameter information, where each set of multimedia parameter information may include: capability table, picture quality, video quality grade, resolution, bit rate, packing mode and other parameter information. For example, a set of multimedia parameters includes profile-level-id, which is three bytes and specifically includes a first byte avcprofilelndication: for representing image quality; second byte profile _ compatibility: the system comprises a capacity table, a second byte and a third byte, wherein the capacity table is used for representing the corresponding capacity level of the mobile terminal, the capacity table is used for representing the current multimedia supporting capacity level of the mobile terminal, a plurality of capacity tables can be arranged in the mobile terminal, one capacity table is specified through the second byte, and the maximum resolution, frame rate and code rate which can be supported by the mobile terminal are determined through the specified capacity table and the image quality represented by the first byte; the third byte avclevelindication: for indicating the maximum resolution, frame rate, code rate. The first mobile terminal 11 provides at least one set of multimedia parameter information that can be supported and suggested by itself to the called terminal through the call request.
After receiving the call request, the second mobile station 12 as the called end selects a group of multimedia parameter information in the call request according to its own status, and uses the selected group as the finally negotiated multimedia parameter information used in the communication. Of course, if it is found that the first mobile terminal 11 cannot support the multimedia parameter information in the call request, a renegotiation request is sent to the first mobile terminal 11 to request the first mobile terminal 11 to send other multimedia parameter information for rewriting, or at least one set of multimedia parameter information supported by the first mobile terminal 11 is directly sent to the first mobile terminal 11, so that the first mobile terminal 11 selects the multimedia parameter information of the final protocol from the at least one set of multimedia parameter information and feeds back the selection result.
After pressing the answer key, the second mobile station 12 initiates a CALL connection (CALL CONNECT) carrying the finally negotiated multimedia parameter information to the first mobile station 11, so as to establish the CALL.
It is understood that the first mobile terminal 12 is not limited to be a calling terminal and the second mobile terminal is a called terminal, i.e., in other embodiments, the first mobile terminal 12 may be a called terminal and the second mobile terminal may be a calling terminal.
2. And (3) communication: the first mobile terminal 11 and the second mobile terminal 12 are in conversation with the core network through the base station.
The first mobile terminal 11 and the second mobile terminal 12 perform the multimedia communication during the multimedia communication using the finally negotiated multimedia parameter information during the call.
3. The first mobile terminal 11 detects that the multimedia parameters need to be adjusted. For example, the first mobile terminal 11 detects the current signal receiving condition at regular time or in real time during the multimedia communication process, and if it is found that the current signal receiving condition does not meet the setting condition, such as the packet loss rate is too high, it is determined that the multimedia parameters in the multimedia communication need to be adjusted currently.
4. Negotiation request of multimedia parameters. For example, the first mobile terminal 11 determines appropriate sets of multimedia parameter information according to its current network state, packages the determined multimedia parameters in a negotiation request, and sends the negotiation request to the trunking core network 15 through the base station 13. In this example, the negotiation request is extended NAS signaling, and the negotiation request is pre-added to the communication protocol, so that the device can identify the request.
5. The clustered core network 15 forwards the negotiation request to the second mobile terminal 12 via the base station 14.
6. The second mobile terminal 12 obtains multiple sets of negotiated multimedia parameter information from the negotiation request, selects a suitable set of multimedia parameter information according to the current network state, packs the selection result in a confirmation message, and sends the confirmation message to the trunking core network 15 through the base station 14. Wherein the confirmation message is another extended NAS signaling, and is pre-added to the communication protocol, so that the device can recognize the message.
7. The clustered core network 15 forwards the acknowledgement message to the first mobile terminal 11 via the base station 13.
8. And (3) communication: the first mobile terminal 11 and the second mobile terminal 12 both adjust the multimedia parameters in the current multimedia communication according to the multimedia parameter information finally selected by the second mobile terminal 12, and continue the current multimedia communication by using the adjusted multimedia parameters.
For example, a user a of the first mobile terminal 11 and a user B of the second mobile terminal 12 perform a video call, and since the current network speed of the user a and the user B currently in the urban area reaches the set network speed value, the video quality level adopted by the video call is negotiated to be high definition in the call process, the resolution is 1280x83, and the code rate is 3500 Kbps. In the process of a call, the first mobile terminal 11 and the second mobile terminal 12 both count the loss rate of the video key frame within 5s every 5s, and when the user a moves to a suburb, the first mobile terminal 11 detects that the loss rate counted continuously for multiple times (for example, 10 times) exceeds a set threshold (for example, 30%), it is determined that the multimedia parameter adopted by the current video call needs to be adjusted, and two sets of multimedia parameter information matched with the current network state are obtained by querying the corresponding relationship between the network state set in the database and the applicable multimedia parameter information, where, for example, the first set is: the video quality grade is standard definition, the resolution is 640x480, and the code rate is 500 kbps; the second group is: the video quality level is standard definition, the resolution is 83x480, and the code rate is 1000 kbps. The first mobile terminal 11 sends the first extended NAS signaling, i.e., the negotiation request, carrying the two sets of multimedia parameter information to the second mobile terminal 12 through the network formed by the base station and the core network. After receiving the request, the second mobile terminal 12 selects the second set of multimedia parameter information from the request and sends a second extended NAS signaling, i.e., an acknowledgement message, carrying the second set of multimedia parameter information to the first mobile terminal 11, because it detects that the current network status is good. Then, the second mobile station 12 uses the second set of multimedia parameter information to conduct the video call. After receiving the message, the first mobile terminal 11 determines that the multimedia parameters of the current video call are in the second group, and also performs the video call by using the second group of multimedia parameter information. That is, in the following video call, the adopted multimedia parameters are: the video quality level is standard definition, the resolution is 83x480, and the code rate is 1000kbps, and the adjustment is continued in the above way until the two communication ends detect that the multimedia parameters need to be adjusted again.
It should be noted that both ends of the communication in this embodiment may request to initiate the above-mentioned multimedia parameter adjustment, that is, in the above example, the second mobile station 12 may perform the steps similar to those of the first mobile station to detect that the multimedia parameter is adjusted, and perform the negotiation of the multimedia parameter with the first mobile station 11. Of course, in other embodiments, it may be defined that only the calling terminal in both ends of the communication has the right to detect and request adjustment of the multimedia parameters.
In addition, the communication network where the mobile terminal is located is not limited to the LTE trunking private network, and in other embodiments, the communication network may be any wireless communication network.
Specifically, the first mobile terminal and the second mobile terminal in this embodiment may be as described in the following embodiments.
Referring to fig. 4, fig. 4 is a flowchart illustrating a parameter adjustment method for multimedia communication according to an embodiment of the present application. The method is executed by the mobile terminal shown in fig. 1, and the embodiment is executed by the first mobile terminal. Specifically, the method comprises the following steps:
s401: the method comprises the steps that a first mobile terminal detects whether multimedia parameters adopted in the current multimedia communication need to be adjusted or not in the process of carrying out multimedia communication with a second mobile terminal.
For example, during a video call, the first mobile terminal and the second mobile terminal periodically or in real time detect whether multimedia parameters currently used in the video call need to be adjusted. Specifically, the first mobile terminal may determine whether to perform adjustment according to the current network state, and determine that the multimedia parameter used in the current video call needs to be adjusted again if the current network state meets the set adjustment condition. In other embodiments, the first mobile terminal may also determine according to other aspects, such as whether the user switches other multimedia communication modes.
The current network state includes at least one of a packet loss rate, a current network rate, a bandwidth, and a received signal.
In another embodiment, the S401 specifically includes:
the method comprises the steps that a first mobile terminal counts the loss rate of the multimedia key frame in a set time every other set time; and judging whether the loss rate of the multimedia key frames obtained by statistics for a plurality of times exceeds a threshold value, if so, determining that the multimedia parameters adopted in the current multimedia communication need to be adjusted.
S402: and when the multimedia parameters are detected to be adjusted, generating a negotiation request of the multimedia parameters, and sending the negotiation request to the second mobile terminal.
In this embodiment, the negotiation request includes at least one set of multimedia parameter information to which adjustment is suggested. The negotiation request for generating multimedia parameters in S402 may specifically include: determining at least one set of multimedia parameter information suitable for a current network state; generating a negotiation request containing the determined at least one group of multimedia parameter information.
For example, the first mobile terminal prestores corresponding relationships between different network states and multimedia parameter information to be adopted by the different network states. When the multimedia parameters in the multimedia communication need to be readjusted, at least one group of multimedia parameter information corresponding to the current network state is searched from the pre-stored corresponding relation, a negotiation request carrying the at least one group of multimedia parameter information is generated, and the request is sent to the second mobile terminal.
The corresponding relation can be configured by a user or learned by the first mobile terminal through historical multimedia communication records.
S403: and when receiving a confirmation message sent by the second mobile terminal in response to the negotiation request, adjusting the multimedia parameters adopted in the multimedia communication according to the confirmation message.
In this embodiment, the confirmation message includes a selection result of at least one group of multimedia parameter information carried in the negotiation request. The S403 includes: determining a group of finally negotiated multimedia parameter information according to the selection result in the confirmation message; and correspondingly adjusting the multimedia parameters adopted in the multimedia communication by adopting the determined multimedia parameter information.
In the above example, the second mobile terminal selects a group of multimedia parameter information that matches its current network state and that the second mobile terminal can support from the received negotiation request, generates a confirmation message carrying the selection result, and sends the confirmation message to the first mobile terminal. The selection result may be a set of multimedia parameter information or an identifier thereof, or a character indicating confirmation selection or non-selection.
If at least one group of multimedia parameter information carried in the negotiation request can not meet the selection condition, the selection result carried by the confirmation message received by the first mobile terminal is not selected, so other multimedia parameter information is selected again according to the current network state and carried into a new negotiation request to be retransmitted to the second mobile terminal, and the first mobile terminal can repeat the step until the second mobile terminal confirms that one group of multimedia parameter information is selected from the second mobile terminal.
And after the first mobile terminal determines a group of multimedia parameter information selected by the second mobile terminal according to the confirmation message, the first mobile terminal adopts the determined multimedia parameter information to carry out the current multimedia communication with the second mobile terminal.
In this embodiment, during the multimedia communication with the second mobile terminal, the first mobile terminal detects whether the adopted multimedia parameters need to be adjusted, renegotiates the multimedia parameter information with the second mobile terminal when detecting that the adopted multimedia parameters need to be adjusted, and continues the multimedia communication by using the negotiated multimedia parameter information, so that the adaptive adjustment of the multimedia parameters during the communication process is realized, the problems of packet loss and the like caused by the mismatch of the current multimedia parameters are avoided, the multimedia communication quality is further ensured, the phenomena of communication blockage, mosaic and the like caused by the change of wireless signals of a user during the mobile process can be greatly reduced, and the use perception of the user is improved.

The method is performed by the mobile terminal shown in fig. 1 and the embodiment is performed by a second mobile terminal. Specifically, the method comprises the following steps:
s501: and in the process of carrying out multimedia communication with the first mobile terminal, the second mobile terminal receives a negotiation request of multimedia parameters sent by the first mobile terminal.
S502: and determining the negotiated multimedia parameter information according to the negotiation request.
The negotiation request may be as described in the above embodiment, and this S502 includes: selecting the at least one group of multimedia parameter information in the negotiation request to obtain the finally negotiated multimedia parameter information, which specifically includes: selecting the multimedia parameter information suitable for the current network state from the at least one group of multimedia parameter information in the negotiation request as the negotiated multimedia parameter information.
S503: sending a confirmation message to the first mobile terminal to inform the first mobile terminal of the determined multimedia parameter information.
For example, when receiving the negotiation request in the above embodiment, the second mobile terminal parses the negotiation request to obtain at least one set of multimedia parameter information carried by the negotiation request, and selects one set of multimedia parameter information that is matched with the current network state of the second mobile terminal and that can be supported by the second mobile terminal from the at least one set of multimedia parameter information, that is, the finally negotiated multimedia parameter information, and generally, if there are multiple sets of parameter information that satisfy the above conditions, it is preferred to select parameter information with high multimedia quality. The second mobile terminal generates a confirmation message carrying the selection result and sends the confirmation message to the first mobile terminal, so that the first mobile terminal can readjust the multimedia parameters in the multimedia communication according to the selection result. The selection result may be a set of multimedia parameter information or an identifier thereof, or a character indicating confirmation selection or non-selection.
If at least one group of multimedia parameter information carried in the negotiation request cannot meet the selection condition, sending a confirmation message indicating that the character is not selected as described in the above embodiment, so that the first mobile terminal performs negotiation again; or the second mobile terminal selects at least one group of multimedia parameter information meeting the selection condition according to the current network state, and generates a confirmation message carrying the at least one group of multimedia parameter information to the first mobile terminal, the first mobile terminal executes the steps S501-S503 to select a group of multimedia parameter information from the multimedia parameter information and feeds back the multimedia parameter information, and the steps are repeated until the terminal confirms that a group of multimedia parameter information is selected from the message sent from the opposite terminal, namely, at this moment, the two communication terminals negotiate the multimedia parameters finally.
S504: and when a group of multimedia parameter information is finally negotiated with the first mobile terminal, correspondingly adjusting the multimedia parameters adopted in the multimedia communication by adopting the finally negotiated multimedia parameter information.
After the multimedia parameter information is finally negotiated, the first mobile terminal and the second mobile terminal both adjust the multimedia parameters adopted in the multimedia communication according to the finally negotiated multimedia parameter information, and continue the multimedia communication by adopting the adjusted multimedia parameters.
It is to be understood that, the first mobile terminal and the second mobile terminal do not have to select the multimedia parameter information according to the current network status, and in other embodiments, the selection may be performed according to the parameter requirement in the multimedia communication mode switched by the user in the mobile terminal, and therefore, how to select the multimedia parameter information is not limited herein.
In the above embodiment, the negotiation request and acknowledgement message may be extended NAS signaling, i.e. two new NAS signaling redefined to be different from the existing NAS signaling. The multimedia parameters comprise at least one of resolution, code rate, frame rate, bit rate, video quality grade, capability table, image quality and packaging mode, and the multimedia communication is video communication. The current network state includes at least one of a current network rate, a bandwidth, and a received signal.
