Description
Technical Field
The invention belongs To the technical field of Mission Critical Push To Talk (MCPTT), and particularly relates To a method and a device for switching To an MCPTT working group.
Background
The international standards organization third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) announces MCPTT as part of the LTE standard. MCPTT is defined as an all-IP application layer service operating on an LTE network, which combines the advantages of large bandwidth, low latency, easy large-scale networking, etc. using an IMS domain-based implementation scheme, and has considerable advantages over the existing technologies. The MCPTT service provides an enhanced PTT service, is suitable for scenes of executing key tasks, and supports functions of authentication, group attachment, group management, group calling, single calling, priority calling, floor control, position reporting and the like.
In the existing 3GPP multicast specification, when a user is interested in some groups and wants to activate the groups, the user can join in a group session to listen and initiate an interest (afterknowledge) procedure for the groups. Conversely, if the user no longer wishes to be interested in certain groups, a de-interestingness procedure is initiated for those groups.
In the prior art, when a user monitors a certain group, pressing a push-to-talk (PTT) button initiates a request for requesting the right to speak, and a server decides to grant the right to speak to the user after judgment, so that the user can speak in the monitoring group.
However, if the user is listening in a group, pressing the PTT key can only talk in the group currently listening, but not in the group the user wants to talk. Furthermore, if the group that the user is speaking happens to be the group that the user wants to speak, if a higher priority group of interest is established, the user is pulled to the higher priority group of interest and cannot continue speaking in the group that the user wants to speak.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
FIG. 1 is an exemplary flow diagram of a group-directed process of interest in the prior art.
In fig. 1, when the MCPTT client monitors the active group, if the user presses the PTT key to initiate a request for requesting the right to speak, the server decides to grant the right to speak to the user after the decision, and the user can speak in the group.
The applicant found that: in the prior art, when a user listens to a certain group, pressing the PTT key may talk in the listening group. However, the listening group may not be the group that the user really wants to speak, thereby causing inconvenience to the user. Furthermore, when a user is speaking in a certain group, if a group of interest with a higher priority is established, the user is pulled to the group of interest with the higher priority, and cannot continue speaking in the original group, thereby interrupting the normal speech of the user.
Thus, the applicant has appreciated that: the current users have the following requirements: it is desirable to set up an MCPTT group (e.g., named as a workgroup) that can quickly switch to talk in the set workgroup when the PTT button is pressed, regardless of whether the MCPTT client is in an idle state or listening to a certain MCPTT group. However, the current state of the art does not support fast switching to workgroup for talkaround. In addition, applicants have also appreciated that: even if the workgroup is set, based on the prior art, if the user is speaking in the workgroup, if a higher priority interest group is established, the user is pulled to the higher priority interest group and cannot continue speaking in the workgroup.
In order to solve the technical problem, in the embodiment of the invention, when the PTT key is detected to be pressed by the user, uninteresting operation is automatically carried out on the groups except the working group, then the group enters the working group to carry out talkback, and the previous interested group list is automatically recovered after the user finishes talking.
Fig. 2 is a flow chart of a method of switching to an MCPTT working group according to the present invention.
As shown in fig. 2, the method includes:
step 201: and determining the MCPTT working group, and adding the MCPTT working group into the interested group list.
Here, the user determines a group desired to talk on the MCPTT client, determines the group desired to talk as an MCPTT working group, and adds the MCPTT working group to the list of interested groups. In other words: the MCPTT working group determined by the user has the following characteristics: no matter the MCPTT client side is in an idle state or monitoring a certain MCPTT group, when a PTT button is pressed, the MCPTT client side can be quickly switched to the set working group to talk. After the user determines the MCPTT working group on the MCPTT client, the working group can be forcibly set as an interested group and added to the interested group list. Preferably, the MCPTT client reports the list of interested groups to the group management server.
Step 202: and when the request for applying the speaking right is detected, the groups except the MCPTT working group in the interested group list are set to be in a non-interested state.
Here, when a request for applying for the talk burst is detected, the groups except the MCPTT working group in the interest group list are set to a non-interest state.
For example, it is assumed that the interest group list of the user includes an interest group 1, an interest group 2, an interest group 3, an interest group 4, and an interest group 5, where the interest group 4 is the working set in step 201. Then, when the request for requesting the right to speak is detected in step 202 (for example, it is detected that the PTT button of the MCPTT terminal is pressed), all the interested groups except the interested group 4 in the interested group list are set to the non-interested state. That is, the group of interest 1, the group of interest 2, the group of interest 3, and the group of interest 5 are set to the non-interest state. At this time, the interested group list includes only the working set in step 201, i.e., the interested group 4.
Step 203: a main talk is initiated in the MCPTT working group.
When the working group is in the non-activated state, the working group is activated; join the workgroup and initiate a talkback in the workgroup. And, when the workgroup is in the active state, joining the workgroup; a master talk is initiated in the workgroup. At this point, the user may initiate a main talk in the MCPTT working group.
Step 204: when the request for releasing the speaking right is detected, the groups in the non-interesting state are added to the list of the interesting groups again.
Here, when the request for releasing the floor is detected, the group set to the non-interested state in step 202 is newly added to the interested group list.
For example, it is assumed that the user interest group list includes an interest group 1, an interest group 2, an interest group 3, an interest group 4, and an interest group 5, where the interest group 4 is the working set in step 201. When it is detected in step 202 that the PTT button of the MCPTT terminal is pressed, all the interest groups except the interest group 4 in the interest group list are set to a non-interest state in step 202. That is, the group of interest 1, the group of interest 2, the group of interest 3, and the group of interest 5 are set to the non-interest state in step 202. At this time, the interested group list includes only the working set in step 201, i.e., the interested group 4. The user may then initiate a talkback in the group of interest 4 in step 203.
Then, when a request for releasing the talk burst is detected (e.g., when the PTT button is detected to be released) in step 204, the non-interested group is added to the interested group list again. At this time, the group of interest 1, the group of interest 2, the group of interest 3, and the group of interest 5 are reset to the state of interest. At this time, the interest group list includes an interest group 1, an interest group 2, an interest group 3, an interest group 4, and an interest group 5. When a higher priority group of interest is established, the user may be pulled to the higher priority group of interest.
Based on the above description, the embodiment of the present invention further provides a device for switching to the MCPTT working group.
Fig. 3 is a block diagram of a device that switches to the MCPTT working group according to the present invention.
As shown in fig. 3, the apparatus includes:
a working group determining module 301, configured to determine an MCPTT working group, and add the MCPTT working group to the list of interested groups;
a non-interest module 302, configured to set, when a request for applying for a talk right is detected, a group in the interest group list other than the MCPTT working group to a non-interest state;
a talkback module 303, configured to initiate a talkback in the MCPTT working group;
an interest module 304, configured to add the non-interest group to the interest group list again when detecting a request to release the talk right.
In one embodiment, the main speaking module 303 is configured to activate the working group when the working group is in an inactive state; and joining the working group and initiating a talkback in the working group.
In one embodiment, the main speaking module 303 is configured to join the workgroup when the workgroup is in an active state; initiating a talkback in the workgroup.
In one embodiment, the detecting the request for applying the speaking right includes: detecting that the PTT button is pressed down when the MCPTT terminal is pressed down; the detecting of the request for applying for the speaking right comprises: detecting that the PTT key is released.
A typical exemplary process of an embodiment of the present invention is described below.
Fig. 4 is an exemplary flow chart of a method of switching to an MCPTT working group according to the present invention.
As shown in fig. 4, the method includes:
step 401: and detecting that the user presses a PTT key on the MCPTT terminal.
Step 402: the MCPTT terminal sends an MCPTT group De-afterinterest request (MCPTT group De-afterinterest request) to the MCPTT server. Here, the MCPTT terminal initiates a De-afterflow procedure.
Step 403: the MCPTT server sends a Group interest status update (Group affinity status update) to the Group management server. And the group management server updates the state of the interested group of the MCPTT user stored by the group management server based on the group interested state update.
Wherein: the group management server sets all groups except the preset MCPTT working group in the interested group list of the MCPTT user to be in a non-interested state.
Step 404: the MCPTT server returns an MCPTT group cancellation interest response (MCPTT group De-afterimage response) to the MCPTT client.
Here, based on the MCPTT group disinterest response, the MCPTT client may know that the groups other than the pre-set MCPTT working group have been successfully set to the non-interested state.
Step 405: the MCPTT client exits the currently monitored group call of the non-MCPTT working group.
Here, the MCPTT client exits the currently listening, non-MCPTT workgroup group call. When the MCPTT client is currently monitoring the group calling of the MCPTT working group, the MCPTT client does not quit the group calling of the MCPTT working group.
Step 406: the MCPTT client establishes or enters a group call of the MCPTT working group and can talk.
Step 407: and detecting that the user releases the PTT key on the MCPTT terminal.
Step 408: the MCPTT terminal sends an MCPTT group interest request (MCPTT group affinity request) to the MCPTT server. Here, the MCPTT terminal initiates an affiliation procedure.
Step 409: the MCPTT server sends a Group interest status update (Group affinity status update) to the Group management server. And the group management server updates the state of the interested group of the MCPTT user stored by the group management server based on the group interested state update. Wherein: the group management server sets the interested state for all the groups except the preset MCPTT working group in the interested group list of the MCPTT user, namely, the group set to the non-interested state in the step 403 is recovered to the interested state.
Step 410: the MCPTT server returns an MCPTT group interest response (MCPTT group affinity response) to the MCPTT client.
Here, based on the MCPTT group interest response, the MCPTT client may know that the group set to the non-interest state in step 403 has been successfully restored to the interest state.
Step 411: when a higher priority group of interest is established than the currently listening group of interest (e.g., MCPTT working group), listening may be entered into the higher priority group of interest session.
In the above procedure, the user may designate a specific group as a working group, which is forced to be the group of interest, and configure the response mode of pressing the PTT button to immediately return to the working group talk mode. When a user presses a PTT key, the MCPTT client records a list of current interested groups, then initiates a de-afterflow process, sets all the groups except a working group in the list to be in a non-interested state, and at the moment, the MCPTT client does not monitor group sessions except the non-working group, wherein if the user monitors the non-working group, the MCPTT client executes a group exit process to exit the monitored group calling.
If the working group is in an inactive state, the MCPTT client initiates the establishing process of the group call, activates the working group and then talks in the working group; if the working group is already in the activated state, the MCPTT client initiates a process of joining the group call, initiates an emergency right process after successfully joining the working group, and talks in the working group after obtaining the talk right.
When the user finishes speaking in the working group and releases the PTT speaking right, the MCPTT client initiates an afterversion process according to the list of the current interested groups stored before, and restores the groups to be in the interested group state, and then the MCPTT client can enter the interested group session with higher priority to monitor.
