Description
Technical Field
The invention belongs to the technical field of Long Term Evolution (LTE), and particularly relates to a meticulous monitoring method and a meticulous monitoring system for a group in an LTE broadband cluster.
Background
LTE is a long term evolution of The Universal Mobile Telecommunications System (UMTS) technology standard established by The third Generation Partnership project (3 gpp) organization.
A trunking communication system refers to a mobile communication system in which a plurality of users share a set of radio channels and dynamically use these channels. The trunking communication system wins praise in the market with complete scheduling function and excellent performance. However, with the emerging applications of cloud computing, internet of things, big data and the like, the enterprise operation flow and production system are deeply changed, the requirements of all industries on 'comprehensive control and field visibility' in the communication process are increased day by day, and the traditional cluster mode based on narrow bands is more and more difficult to continue. In a narrowband trunking system, aiming at a point-to-point private call, a scheduling system has a function of careful monitoring, namely, a user is appointed to conduct careful monitoring, and when the user conducts the point call, a monitoring person (often an authorized scheduling person) can monitor the call of the user and is not discovered by two parties of the call.
With the LTE technology in public networks, group communication is coming to be broadband. The broadband digital trunking communication system is a dedicated mobile communication system which is based on broadband mobile communication technology and provides a command scheduling function in a multimedia trunking service mode. The method can realize the cooperative fusion scheduling capability of multiple services such as voice scheduling, data scheduling, video scheduling and the like.
In a broadband trunking system, there are scenarios that require listening to a group. However, in the broadband trunking system defined by the current 3GPP protocol, the implementation of the group-specific careful monitoring function is still blank, and the functional requirements and implementation methods for group-specific monitoring are not proposed.

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, "comprising" means "including but not limited to", "according to … …" means "according to at least … …, but not according 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.
In the embodiment of the invention, function definition, a flow mechanism and an authorization mechanism based on meticulous group monitoring are provided.
Fig. 1 is a flowchart of a method for meticulous monitoring of groups in an LTE broadband cluster in accordance with the present invention.
As shown in fig. 1, the method includes:
step 101: a Critical task (MC) service client (service client) sends a meticulous listening activation request (listening activation request) to a Critical task service server (MC service server), wherein the meticulous listening activation request comprises an identification of a group needing meticulous listening.
Step 102: the critical task service server returns a meticulous listening activation response (Discreet listening activation response) corresponding to the meticulous listening activation request to the critical task service client.
The key task service server judges whether a key task service client sending meticulous monitoring activation requests has monitoring authority and judges whether a group needing meticulous monitoring has monitored authority, if at least one of the key task service client sending meticulous monitoring activation requests has no authority, failure response is sent to the key task service client, wherein the result carries specific reasons, and if not, successful monitoring response is sent.
Specifically, the method comprises the following steps:
(1) And when the key task service server judges that the key task service client does not have meticulous monitoring authority, the key task service server returns meticulous monitoring activation failure response to the key task service client.
(2) And when the key task service server judges that the group needing careful monitoring does not have the meticulous monitoring authority, the key task service server returns meticulous monitoring activation failure response to the key task service client.
(3) And when the critical task service server judges that the critical task service client does not have meticulous monitoring authority and a group needing meticulous monitoring does not have meticulous monitoring authority, the critical task service server returns meticulous monitoring activation failure response to the critical task service client.
(4) And when the key task service server judges that the key task service client has the meticulous monitoring authority and the group needing the meticulous monitoring has the meticulous monitoring authority, the key task service server returns meticulous monitoring activation response to the key task service client.
In the specific implementation, the original MC service ID in the existing meticulous monitoring activation request in the prior art can be changed to be optional, and the identification of the group of the meticulous monitoring (MC service group ID) is added to serve as the meticulous monitoring activation request of the embodiment of the invention. Preferably, the meticulous-monitoring-enabled response also carries an optional meticulous-monitoring group identification (MC service group ID).
It can be seen that the instruction issuing process based on the meticulous monitoring can be realized based on the flow of fig. 1.
In addition, the embodiment of the invention also provides a group-based meticulous monitoring cancellation command issuing process.
Fig. 2 is a flowchart of careful monitoring of cancellation groups in an LTE broadband cluster in accordance with the present invention.
As shown in fig. 2, the method includes:
step 201: the key task service client sends meticulous listening deactivation request (meticulous listening activation request) to the key task service server, wherein the meticulous listening deactivation request comprises identification of a group needing to cancel meticulous listening.
Step 202: the critical task service server returns a meticulous listening deactivation response (Discreet listening activation response) corresponding to the meticulous listening deactivation request to the critical task service client.
Here, when the mission critical service server determines that meticulous monitoring deactivation can be successfully performed for the group needing to cancel, returning a successful deactivation response to the mission critical service client; and when the key task service server determines that the meticulous monitoring deactivation cannot be successfully carried out aiming at the group needing to cancel the meticulous monitoring, returning a deactivation failure response to the key task service client.
Wherein, when the meticulous monitoring deactivation response is the meticulous monitoring deactivation success response, the group conversation of the group needing to cancel the meticulous monitoring is in the established state and the key task service client terminal is added into the group conversation of the group, the key task service client terminal is quitted (bye) the group conversation of the group needing to cancel the meticulous monitoring.
In a specific implementation, an original MC service ID of an existing request for meticulous monitoring deactivation in the prior art may be changed to be optional, and an optional identifier (MC service group ID) of a group that needs to cancel meticulous monitoring may be added as the request for meticulous monitoring deactivation according to the embodiment of the present invention. Preferably, the meticulous monitoring deactivation response also carries an optional identifier (MC service group ID) of the group needing to cancel meticulous monitoring.
Based on the flows of fig. 1 and fig. 2, the timing control of joining and exiting snooping can be realized.
In one embodiment, a group session of a group requiring careful monitoring is in an established state before a mission critical services client sends a careful monitoring activation request to a mission critical services server. Wherein, when the meticulous monitoring activation response is a meticulous monitoring activation successful response, the method further comprises: sending meticulous monitoring group call requests to a key task service client when a key task service server determines that group conversations of a group needing meticulous monitoring are in an established state, wherein the meticulous monitoring group call requests comprise identifiers of the group needing meticulous monitoring; the key task service client returns meticulous monitoring group call responses corresponding to the meticulous monitoring group call requests to the key task service server.
Preferably, the mission critical service server joins the mission critical service clients to the group session when the meticulous monitoring of the group call responses is meticulous to the successful group call responses. At this time, the mission-critical service client serves as a listener, and can perform local recording on the monitored content when the call content and the talkback information of the group can be acquired.
In one embodiment, when the meticulous monitoring of activation responses is meticulous monitoring of activation success responses and a group session of a group requiring meticulous monitoring is not established, the method further comprises: the method comprises the steps that after a key task service server waits for a group conversation of a group needing careful monitoring to be established, a meticulous monitoring group call request is sent to a key task service client, wherein the meticulous monitoring group call request comprises an identification of the group needing careful monitoring; and the key task service client returns meticulous monitoring group call response corresponding to the meticulous monitoring group call request to a key task service server.
Preferably, the mission-critical service server joins the mission-critical service client to the group session when the monitoring-meticulous group call response is a monitoring-meticulous group call successful response. At this time, the mission-critical service client serves as a listener, and can perform local recording on the monitored content when the call content and the talkback information of the group can be acquired.
Based on the embodiment of the present invention, in a cluster scheduling system of an LTE broadband cluster, when a scheduling station or a user terminal is implemented as a mission-critical service client shown in fig. 1 and 2, the scheduling station or the user terminal may perform meticulous monitoring on a specific group. When the group establishes and switches the talkback, the dispatching desk or the user terminal as the listener can acquire the conversation content and the talkback information of the group, and the dispatching desk or the terminal as the listener can also perform local sound recording on the monitored content.
Furthermore, the embodiment of the invention also realizes a perfect authorization mechanism, which comprises the following steps: the monitor needs to have the authority to monitor the group, and only authorized monitors can monitor the group; snooped groups need to have snooped permissions, only authorized groups can be snooped, and so on. In addition, in the embodiment of the invention, the commands related to meticulous monitoring comprise starting meticulous monitoring and ending meticulous monitoring; when careful monitoring is finished, the current session and subsequent sessions of the group cannot be monitored.
Embodiments of the present invention may be embodied in a variety of application scenarios.
For example, the embodiments of the present invention may be specifically implemented in an application scenario of Mission critical push-to-talk (MCPTT). MCPTT is an all-IP application layer service running on an LTE network, and the implementation scheme based on the IMS domain is used, so that the advantages of large bandwidth, low delay, easiness in large-scale networking and the like are integrated. The enhanced PTT service provided by the MCPTT 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.
Moreover, the group meticulous monitoring service process of the embodiment of the invention can have the following two commonly used scenes:
(1) Meticulous monitoring that the group is not active at the beginning (i.e., the group session is in an un-established state);
(2) Meticulous monitoring begins when the group is active (i.e., the group session is in an established state).
It will be appreciated by those skilled in the art that the implementation of the embodiments of the present invention in MCPTT application scenarios, which will be described in detail below, is only an exemplary illustration and is not intended to limit the scope of the embodiments of the present invention.
Fig. 3 is a flowchart of a group listen command process with a group session in an un-established state according to the present invention. Fig. 4 is a schematic diagram of a group listen command process with a group session in an un-established state according to the present invention.
As can be seen from fig. 4, the main logical network elements of the system architecture include a Dispatch Console (DC), a User Equipment (UE), and an MCPTT server (MCPTTServer). The scheduling console integrates a scheduling control interface, can retrieve, download and play back historical videos, and can perform scheduling operation on the videos, such as distribution and wall climbing. The user terminal is a wireless terminal device developed based on LTE and can support high-resolution video playing. The MCPTT server provides key cluster services for the 3GPP scheduling server. The MCPTT Client (MCPTT Client) is a 3GPP trunking service Client, and may be specifically implemented as a dispatcher station or a user terminal.
As can be seen in fig. 4, the group session for group a, which includes UE1 and UE2, was in an unacknowledged state prior to the careful monitoring. First, a dispatch station, acting as a listener, sends a meticulous listening command. Then, a group session for group a is established. Then, the dispatcher station may then listen to the group session for group a.
Fig. 3 depicts an implementation of a group listen command with a group session in an un-established state. In fig. 3, the MCPTT client 3 is a listener (either a dispatch station or a user terminal). The MCPTT client 3 has previously submitted a listening request for a group (e.g., group a in fig. 4) to the MCPTT server before the group session of the group is established, and the MCPTT server returns a listening success message to the MCPTT client 3. The MCPTT client 1 (e.g., UE1 in group a) then establishes a group session for that group a, and the MCPTT server is responsible for establishing the group session to the other group members (e.g., UE 2). The MCPTT server judges whether the group A is monitored, if so, the MCPTT server establishes a group conversation to the monitor MCPTT client 3, which is equivalent to the MCPTT server taking the MCPTT client 3 as a group member to join the group conversation of the group A. Finally, the group session of the group a is successfully established, and the MCPTT client 3 can monitor the group session, including being able to obtain the change of the talkback information.
As shown in fig. 3, the method includes:
step 301: the MCPTT client 3 (e.g., the dispatch station in fig. 4) acting as a listener sends a meticulous listening activation request (listening activation request) to the MCPTT server, which includes an identification of a group that needs to be listened to (e.g., an identification of group a).
Step 302: the MCPTT server returns, to the MCPTT client 3 as the listener, a meticulous listening activation response (listening activating response) corresponding to the meticulous listening activation request, wherein the meticulous listening activation response carries an identification of the group that needs to be meticulous listening. The MCPTT server judges whether the MCPTT client side 3 sending the meticulous monitoring activation request has monitoring authority and judges whether a group needing to be monitored has monitored authority, if at least one of the MCPTT client side 3 does not have the authority, failure response is sent to the MCPTT client side 3, the result carries a specific reason, and if not, successful monitoring response is sent. The subsequent flow steps 303 to 309 describe the processing procedure after the MCPTT server sends a successful listening response to the MCPTT client 3.
Step 303: MCPTT client 1 (e.g., UE1 in Group a) sends a Group session request (Group call request) to the MCPTT server.
Step 304: the MCPTT server sends a Group session request (Group call request) to the MCPTT client 2, e.g., UE2 in Group a.
Step 305: when the MCPTT server determines that a Group session of the Group needing careful monitoring is in an established state, sending a meticulous monitoring Group call request (monitoring Group call request) to the MCPTT client 3, wherein the meticulous monitoring Group call request comprises an identification of the Group needing careful monitoring (for example, an identification of the Group A).
Step 306: the MCPTT client 2 returns a Group call response (Group call response) to the MCPTT server indicating that the MCPTT client 2 can join the Group session.
Step 307: the MCPTT client 3 returns a meticulous listening Group call response (listening Group call response) to the MCPTT server, which also includes the identity of the Group that needs to be meticulous. It is assumed here that the careful listening of group call responses is a successful response.
Step 308: the MCPTT server sends a Group call response (Group call response) to the MCPTT client 1 indicating that the MCPTT client 1 can join the Group session.
Step 309: and establishing a media plane. So far, the MCPTT client 3 has joined the group session as a listener, can acquire the conversation content and the talkback information of the group, and can also perform local recording on the monitored content.
Fig. 5 is a flowchart of a group listen command process with a group session in an established state according to the present invention. Fig. 6 is a diagram illustrating a group listen command process with a group session in an established state according to the present invention.
As can be seen from fig. 6, the main logical network elements of the system architecture include a Dispatch Console (DC), a User Equipment (UE), and an MCPTT server (MCPTTServer). The scheduling console integrates a scheduling control interface, can retrieve, download and play back historical videos, and can perform scheduling operation on the videos, such as distribution and wall climbing. The user terminal is a wireless terminal device developed based on LTE and can support high-resolution video playing. The MCPTT server provides key cluster services for the 3GPP scheduling server. The MCPTT Client (MCPTT Client) is a 3GPP trunking service Client, and may be specifically implemented as a dispatcher station or a user terminal.
As can be seen in fig. 6, the group session for group a, which includes UE1 and UE2, was in the established state prior to the careful monitoring. First, a group session for group a is in progress. Then, the dispatch station as a listener sends meticulous listening commands. Then, the dispatcher station may then listen to the group session for group a.
Fig. 6 depicts an implementation of a group listen command with a group session in an established state. In fig. 6, MCPTT client 1 (which may be either a dispatcher or a user terminal) establishes a group session. The MCPTT server is then responsible for establishing a group session to the other group member MCPTT clients 2. In the process of session proceeding, the MCPTT client 3 as the listener successfully submits a request for monitoring the group session to the MCPTT server, and the MCPTT server sends a monitoring success message to the MCPTT client 3. The MCPTT server needs to determine whether the group session is already established, and if so, establish the group session to the listener MCPTT client 3, which is equivalent to the MCPTT server joining the MCPTT client 3 as a group member in the group session. Finally, the MCPTT client 3 joins the group session, and the MCPTT client 3 can listen to the group session, including being able to obtain the change of the talkback information.
As shown in fig. 5, the method includes:
step 501: MCPTT client 1 (e.g., UE1 in Group a) sends a Group session request (Group call request) to the MCPTT server.
Step 502: the MCPTT server sends a Group session request (Group call request) to the MCPTT client 2, e.g., UE2 in Group a.
Step 503: the MCPTT client 2 returns a Group session response (Group call response) to the MCPTT server indicating that the MCPTT client 2 can join the Group session.
Step 504: the MCPTT server returns a Group session response (Group call response) to MCPTT client 1 indicating that MCPTT client 1 can join the Group session.
Step 505: and establishing a media plane. At this point, the group session has already been established.
Step 506: the MCPTT client 3 (e.g., the dispatch station in fig. 4) acting as a listener sends a meticulous listening activation request (listening activation request) to the MCPTT server, which includes an identification of a group that needs to be listened to (e.g., an identification of group a).
Step 507: the MCPTT server returns meticulous listening activation response (listening speaking response) corresponding to the meticulous listening activation request to the MCPTT client 3 which is taken as a listener, wherein the meticulous listening activation response carries the identification of the group needing meticulous listening. The MCPTT server judges whether the MCPTT client side 3 sending the meticulous monitoring activation request has monitoring authority and judges whether a group needing to be monitored has monitored authority, if at least one of the MCPTT client side 3 does not have the authority, failure response is sent to the MCPTT client side 3, the result carries a specific reason, and if not, successful monitoring response is sent. The subsequent flow steps 508 to 510 describe the processing procedure after the MCPTT server sends a successful listening response to the MCPTT client 3.
Step 508: when the MCPTT server determines that the Group conversation of the Group needing careful monitoring is in the established state, sending a meticulous monitoring Group call request (meticulous monitoring Group call request) to the MCPTT client 3, wherein the meticulous monitoring Group call request comprises the identification of the Group needing careful monitoring (such as the identification of the Group A).
Step 509: the MCPTT client 3 returns a meticulous listening Group call response (listening Group call response) to the MCPTT server, which also includes the identity of the Group that needs to be meticulous. It is assumed here that the meticulous listening to group call responses is a successful response.
Step 510: and establishing a media plane. Thus, the MCPTT client 3, as a listener, has joined the group session, and can acquire the conversation content and the talkback information of the group, and can perform local recording on the monitored content.
Based on the above description, the embodiment of the present invention further provides a meticulous monitoring system for the group in the LTE broadband cluster.
