Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
First, the method provided in this embodiment of the present application may be applied to a system architecture shown in fig. 2, where the system architecture may include a plurality of terminal devices (e.g., UE1, UE2, and UE3 in fig. 2), a DC (Dispatch Client), a GIS + IMS (having an IMS function in a GIS), an EPC (Evolved Packet Core), a base station, and the like (this example only shows a device related to the method provided in this embodiment of the present application, and in a specific application scenario, if it is necessary to use other structural devices, this is not specifically limited here). In the system architecture, information interaction between the DC and a plurality of terminal devices is realized through the EPC.
Based on the above usage scenarios, the method and apparatus provided by the embodiments of the present application are further described in detail below with reference to the accompanying drawings and specific application scenarios:
example one
As shown in fig. 3, an embodiment of the present application provides a positioning communication method based on a geographic information system GIS, where the method may include:
step 301, the GIS stores the attribute information reported by the first terminal equipment; displaying the attribute information at a position corresponding to the position information on a map based on the position information in the attribute information;
wherein, the GIS in this embodiment may be a GIS server; the attribute information may include multiple items, where the multiple items may specifically be a user name, a communication identification number (e.g., a telephone number, a nailing contact, a wechat contact, and the like), and longitude and latitude information of a user corresponding to the first terminal device.
There are various ways of displaying attribute information on a displayed map interface; for example: an icon can be displayed at the position corresponding to the first terminal device, and various small icons in the icon display various attribute information (the communication identifier can selectively display the icon or specific identifier information according to the level corresponding to the terminal device; if the communication identifier is a telephone number, the specific display for users at different levels can be that the icon is directly displayed for users at high levels, and the specific telephone number or instant communication contact way is directly displayed for users at low levels, etc.).
In addition, after the position information reported by the terminal equipment is acquired by the GIS server in the embodiment, the position information reported in a set time period is combined to form a historical track record of the terminal equipment, and the historical track record is stored as a part of the attribute information; in addition, in order to ensure real-time updating of data and effective utilization of storage space, the historical track record can be cleared according to record clearing time set by a user. The terminal equipment can inquire the information of the self moving track, the service operation (such as audio and video call and video monitoring) and the like in the effective period according to the conditions of time period, position and the like.
Step 302, when receiving an audio/video service initiated by the scheduling client DC based on the displayed attribute information, establishing a dedicated bearer corresponding to the audio/video service, so that the first terminal device and the scheduling client DC implement the audio/video service through the dedicated bearer.
By the method provided by the embodiment, the DC can initiate services such as audio and video and the like to the designated terminal equipment through the GIS map, the IMS realizes the control of the whole audio and video session, and selects a more suitable bearer for data transmission through the EPC network, so that the communication quality of the audio and video is improved.
Specific steps for implementing the method provided by the embodiment of the present application based on the system architecture shown in fig. 2 may include, as shown in fig. 4:
step 401, after a terminal device (which may be a UE) is powered on, the terminal device successfully attaches to an EPC network; and successfully register to the IMS network;
step 402, the terminal device periodically reports the location information to the GIS, including: user name, telephone number, location information (e.g., latitude and longitude information), status information, etc.;
step 403, the GIS stores the position of the terminal device and the user information;
in step 404, after the DC acquires the map from the GIS, the attribute information of the UE may be presented on the map in an icon manner.
In this embodiment, the attribute information reported in real time based on the UE includes location information, and the location information is also real-time, so that the movement track and the like of the UE can be further determined according to the comprehensive analysis of the real-time location information. Therefore, based on the attribute information reported by the UE in real time, more relevant information of the UE can be presented on the DC side.
After the GIS server acquires the position information reported by the terminal equipment, the GIS server can automatically store the historical track record of the user and flexibly configure the record clearing time. The terminal equipment user can conveniently inquire the information of the user moving track, the service operation (such as audio and video call and video monitoring) and the like in the effective period according to the conditions of time period, position and the like.
Further, after the terminal equipment is successfully registered and the position is reported, the DC can initiate audio and video services to the UE through the GIS map. And the GIS sends an audio/video service request to an Evolved Packet Core (EPC) through an IP multimedia core network subsystem (IMS), so that the EPC establishes a special bearer corresponding to the service type of the audio/video service request between the first terminal equipment and the scheduling client DC. The specific flow is shown in fig. 5:
step 501, a DC initiates an audio/video service to a designated terminal device (for example, UE3 shown in fig. 2) through a GIS map;
step 502, after receiving the audio/video service request, the IMS sends a request to the EPC to request the establishment of a dedicated bearer according to the service type; the service type may include: audio call, video monitoring and video return.
In the embodiment, the GIS provides the latest UE attribute information to the DC, so that after the DC sends an audio/video service request to a certain UE, the corresponding GIS can update the attribute information of the UE, so that the latest state of the UE can be reflected when the attribute information is displayed in other DCs or UEs; for example, if the DC and the UE1 perform the audio/video service, the state of the attribute information of the corresponding UE1 presented on the map is that the DC performs the audio/video service; other UEs or DCs to establish the audio video service with the UE1 may perform after the status update of the UE1 is to end the audio video service.
The specific procedure for establishing the dedicated bearer may be: after receiving a request for establishing the special bearer by the IMS, the EPC establishes a corresponding special bearer according to the service type indicated by the request, and then sends a successful response of establishing the special bearer to the IMS; after receiving the successful response of the EPC, the IMS returns the successful response of the audio/video service request to the DC, and establishes the special bearing between the DC and the UE successfully.
In the embodiment, the IMS requests the EPC to establish corresponding special load according to different service types initiated by the GIS, so that high-quality audio and video data transmission is ensured.
Step 503, the UE and the DC implement the audio and video service through the dedicated bearer; in this embodiment, the UE and DC audio/video call interface may be superimposed on a GIS map for presentation.
Further, if the DC finishes the audio/video service, the GIS may send an audio/video service end request to the EPC through the IMS, so that the EPC deletes the dedicated bearer according to the audio/video service end request.
The specific implementation process can be as follows: the DC finishes the audio and video service, sends an audio and video service finishing request to the IMS and receives a successful response; the IMS sends a special load deletion request to the EPC; the EPC returns a response of successful deletion of the special load to the IMS; the IMS returns an audio and video service end response to the DC; the DC sends an audio and video end notification to the GIS; and after receiving the end notification, the GIS prompts that the audio and video service of the terminal equipment is ended, and updates the service state of the terminal equipment on the map.
In this embodiment, in the case of establishing a dedicated bearer, information interaction between the DC and the UE may be implemented through the dedicated bearer, and if the dedicated bearer is deleted, the method is switched to an original information interaction manner, so that the method may be compatible with an original information interaction method, specifically: after the dedicated bearer is deleted, the bearer for signaling interaction between the first terminal device and the scheduling client DC is switched to a default bearer provided by the EPC.
In a specific application scenario, a plurality of terminal devices may be in the same group, that is, devices in the group are trusted devices, and devices in the same group may interact with each other in an encrypted environment; and the devices in the group can mutually view the attribute information and carry out information interaction. In this embodiment of the present application, the terminal devices divided into the same group generally have at least one same characteristic, so if a DC needs to initiate an audio/video service to multiple terminal devices at the same time, multiple terminals that need to initiate the audio/video service may be divided into the same group, and then the audio/video service is initiated for the group, where the specific implementation may be:
when receiving a group audio/video service initiated by a scheduling client DC aiming at a first group, the GIS establishes a group dedicated bearer corresponding to the group audio/video service, so that the scheduling client DC and a plurality of terminal devices in the first group realize the audio/video service through the dedicated bearer.
In this embodiment, the group may have a corresponding unique identifier, and after the GIS receives the unique identifier corresponding to a certain group sent by the DC, it may be determined that the DC initiates an audio/video service to the group corresponding to the unique identifier.
Further, in order to implement information protection of the terminal device, when the attribute information of the terminal device is displayed, the attribute information of the terminal device may be displayed based on the group, so that the GIS displays the attribute information of the terminal device at a position corresponding to the position information on the map based on the position information in the attribute information, specifically including:
determining the same group terminal equipment of any terminal equipment receiving the map; wherein, the terminal equipment of any one group and the terminal equipment of the same group belong to the same set group;
acquiring group attribute information of the terminal equipment in the same group;
and the GIS displays the attribute information of the terminal equipment in the same group on a map at a position corresponding to the position information based on the position information of the terminal equipment in the same group in the group attribute information.
By the method, the terminal equipment in the same group can directly view the basic information of the user such as the name, the telephone number, the service state and the like through the terminal icon on the GIS map.
In the embodiment of the application, a plurality of terminal devices under some industry application scenes can be arranged in the same group, so that unified management of users accessing IMS + GIS in an organization mode is realized. For example, after the terminal devices are grouped according to different organizations, the users in the same group can view the real-time positions of all the users in the group through a GIS map. For example, in a scene of engineering survey, when terminal equipment carried by field researchers runs to a certain position, the DC for monitoring in the group can initiate voice indication or video monitoring and other operations on the terminal equipment through the terminal equipment on the GIS map by using the attribute information displayed at the specific position, so that positioning monitoring and audio/video communication can be realized. The method provided by the embodiment of the application can be used for any type of terminal by using a GIS system realized by a B/S architecture and combining the service function provided by the IMS, and can use the positioning function and the communication function as long as the terminal is provided with a browser.
