Reference throughout the specification to "one embodiment" or "another embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in this embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, and as shown in fig. 1, a calling terminal 01 and a called terminal 03 establish a group call through a server 02, for example, the number of the called terminals 03 may be one or more, and this scheme does not require this.
For example, the calling terminal 01 may specifically be a mobile phone, a tablet, a computer, a smart wearable device, and the like, and similarly, the called terminal 03 may specifically be any terminal device such as a mobile phone, a tablet, a computer, a smart wearable device, and the like.
In a network mode according to any network standard, such as a third Generation Partnership project (3 rd gpp) mode, a 3rd-Generation wireless telephone technology (3G) mode, a second Generation wireless telephone technology (2G) mode, etc., a procedure of initiating a group call is that, after a user presses a Push-to-talk (PTT) key of a calling terminal 01, the calling terminal 01 checks a collision management to determine whether a group call can be initiated, i.e., a group call, and if so, a Session Initiation Protocol (SIP) reference message necessary for constructing the group call is generated, the SIP reference message includes a message header field and a message body, the message body is a part satisfying an extensible markup language (XML) format and then is transmitted to a SIP server through a Socket, the SIP reference message is transmitted to a call server 02, and a call server receives a call data set 02 and transmits the call data set 02 data to the SIP server after the call server receives the call data set data.
Based on the above application scenario, the calling terminal 01 needs to construct an SIP REFER message including a message header field and a message body every time when the group is established, however, the construction of each part of the message is time-consuming, which results in a long delay until the calling terminal can communicate with the called terminal after the user operates the calling terminal and presses the PTT key until the group is established. In order to reduce the delay of group establishment, in the embodiment of the present application, a message body of an SIP REFER message is created in advance, and when a user operates a calling terminal 01 to initiate a PTT call request each time, a message header field of the SIP REFER message is created, and then the SIP REFER message is constructed according to the message header field and the message body created in advance.
Fig. 2 is a flowchart illustrating a method for establishing a communication group according to an embodiment of the present application, where as shown in fig. 2, the method includes:
s101: and responding to the user input for starting the PTT call request, and creating a message header field of a session initiation protocol reference SIP REFER message according to the session ID acquired in the session pre-establishment process and the IP address of the calling terminal.
In this step, the calling terminal and the called terminal have already completed session pre-establishment, and at this time, if the user inputs an input for starting a PTT call request, for example, the user presses a PTT button on the calling terminal to trigger starting of the PTT call request, the calling terminal creates a message header field of an SIP REFER message according to the session ID and the identifier of the calling terminal acquired in the session pre-establishment process. Where the session ID, also called Call ID, is a read-only value that uniquely identifies the client that is currently accessing the server. Illustratively, the identification of the calling terminal may include the IP address of the calling terminal and the port of the calling terminal.
Illustratively, the session ID is obtained at a session pre-establishment stage, the calling terminal sends a session pre-establishment request message to the server, the server sends a response message to the calling terminal after receiving the session pre-establishment request message, the response message includes the session ID, and the calling terminal can obtain the session ID according to the response message after receiving the response message returned by the server.
S102: and constructing the SIP REFER message according to the message header field and the message body of the SIP REFER message which is created in advance.
The message body is a part in the SIP REFER message which meets the session description protocol and takes extensible markup language as a format, namely an XML part.
In this step, the header field of the SIP REFER message created in step S101 is combined with the message body of the SIP REFER message created in advance to construct an SIP REFER message.
The message body of the SIP REFER message is created according to the pre-acquired group ID and the call type after the calling terminal is started. After the calling terminal starts, the calling terminal needs to perform group selection to determine the ID of the group, and exemplarily, the calling terminal sets the current call type, for example, the call type of the calling terminal performing the PTT call request with multiple called terminals is a group call, which is also called a group call.
For example, before determining the group ID through group selection, the embodiment of the present application further needs to perform pre-configuration on the current environment, where the pre-configuration includes SIP registration and port configuration.
In the embodiment of the application, when a request for starting the PTT call is received, a message header field of the SIP REFER message is created according to the session ID and the identification of the calling terminal which are obtained in the session pre-establishment process, and the SIP REFER message is constructed according to the message body of the SIP REFER message which is created in advance in the message header field, so that the group establishment time is shortened.
In a specific implementation manner, after the SIP REFER message is constructed according to the message header field and the message body of the SIP REFER message created in advance, the calling terminal sends the SIP REFER message to the server through the Socket, and the server sends a response message to the calling terminal after receiving the SIP REFER message, and gives the calling terminal the speech right, so that the calling terminal can perform group call with the called terminal.
Fig. 3 is a flowchart illustrating another method for establishing a communication group according to an embodiment of the present application, where as shown in fig. 3, the method includes: the calling terminal registers SIP to the server, after the SIP registration is successful, the group is pre-established, after the group is successfully pre-established, the group is selected, after the group selection is successful, the calling terminal receives the group ID sent by the server, and an XML part of an SIP REFER message is pre-established according to the group ID and the call type (group call). And then, after receiving the user input for starting the PTT call request, starting the group establishment process, constructing the message header of the SIP REFER message according to the identification of the calling terminal and the session ID acquired in the session pre-establishment process, simultaneously reading the XML part of the pre-established SIP REFER message from the memory, and then constructing the SIP REFER message according to the message header and the XML part of the SIP REFER message.
