Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

The emergency mission business system can be used for participators and organizations responsible for public safety (such as public security, fire protection, medical treatment and the like) to mutually communicate and coordinate to complete proper treatment of events in public safety events (such as large-scale gatherings, terrorist attacks, natural disasters and the like). The mobile communication network provides transmission resources for emergency mission service systems, e.g. 3GPP networks or non-3 GPP networks.

The emergency task service system may provide multiple emergency task service services, such as emergency task push-to-talk (MCPTT), emergency task video (MCVideo), emergency task data (MCData), at the same time, that is, the emergency task service system supports service servers that deploy multiple service types, such as MCPTT server, MCVideo server, and MCData server.

The deployment of emergency mission business systems typically employs a private network, which may also be referred to as a private network, that serves only one organization or company, such as only the department of public security, or only the fire protection system.

In the related art, a mobile communication network uniformly manages, for example, allocates or releases transmission resources according to QCI, ARP, and the like. Because the mobile communication network does not sense the emergency of the emergency task service system and cannot predict the change of the requirement of the emergency on the network transmission resource, the mobile communication network cannot cope with the dynamic requirement change of the emergency on the priority of the network transmission resource and cannot meet the flexible and dynamic requirement of the emergency task service on the network transmission resource.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

As shown in fig. 1, there is provided an architecture diagram of an emergency mission service system to which the embodiments of the present application can be applied, the system including a priority management device, a service server, and a mobile communication network.

The priority management device is used for managing priority, such as priority ranking, priority modification authorization, or priority arbitration, and is responsible for making an arbitration on a call (including the same service and different service types) or a priority of a user at an application layer. The priority management device may also be referred to as an application layer priority arbitration server, and may be an independent physical device, or may be in a physical entity with other devices, for example, the priority management device may be a service server with a priority management function, and may be referred to as an application layer priority arbitration service server, without limitation.

The service server belongs to an application layer logic entity, and can include two functions: controlling business functions and participating business functions. Controlling service functions may include call control management and transceiving of media plane data; the service function may include routing of user messages. In fig. 1, two service servers are exemplarily provided, the service server 1 and the service server 2 may be the same service type, for example, MCPTT type, or may be different service types, for example, the service server 1 is MCData type, and the service server 2 is MCVideo type, and the application does not limit the number of service priorities. The service server may be a separate physical device or may be in a physical entity with other devices. The control service function and the participation service control can be respectively and independently realized in an independent physical device, and can also be deployed in the same physical device.

A mobile communication network, configured to provide transmission resources for the emergency task service System, and may be a 3GPP network, such as a Long Term Evolution (LTE) network, a Universal Mobile Telecommunications System (UMTS), a Global System for mobile communications (GSM), a 5G communication network, or a next generation communication System; or may be a non-3 GPP network, without limitation. When the emergency task service system uses the LTE network, the service server interacts with a Policy and Charging Rule Function (PCRF) through the Rx reference point to obtain a unicast transmission resource, that is, a unicast bearer, and interacts with the broadcast multicast service center through the MB2 reference point to obtain a broadcast transmission resource, that is, a broadcast bearer. The Service server may interact with a Service Capability Exposure Function (SCEF) to obtain information of the mobile communication network, such as base station congestion information. When the emergency task service system uses a 5G Network, the service server obtains unicast transmission resources by interacting with a Policy Control Function (PCF), obtains broadcast transmission resources by interacting with a Session Management Function (SMF) having a broadcast Management Function, and simultaneously, can obtain mobile communication Network information by interacting with a Network open Function (NEF), such as congestion of an access Network. In fig. 1, a mobile communication network is taken as an LTE network as an example.

Terminal devices, which may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication capability, as well as various forms of terminals, Mobile Stations (MSs), terminals (terminals), User Equipment (UEs), soft terminals, etc., such as water meters, electricity meters, sensors, etc. Specifically, the emergency task service application client may be installed on a terminal device, for example, an APP, and the emergency task service application client transmits call control information or media data information with the emergency task service server through a network transmission service provided by the mobile communication network.

Fig. 2 is a schematic diagram of a 5G mobile communication network. The components in the 5G mobile communication network are briefly described as follows in conjunction with fig. 2:

access and mobility management function (AMF) node: and is responsible for mobility management, access management, and the like, and may be used to implement other functions besides session management in Mobility Management Entity (MME) functions.

Session Management Function (SMF) node: establishing a session for a terminal device, assigning a session Identification (ID), and managing or terminating the session.

User Plane Function (UPF) node: providing functions of session and bearer management, IP address assignment, etc.

Policy Control Function (PCF) node: a network entity (e.g., an access network node or a UPF node) is assigned a security policy.

Unified Device Management (UDM) node: and storing the subscription information of the user.

Data Network (DN): providing external data network services.

Application Function (AF) node: providing application layer services.

Network Exposure Function (NEF), which exposes the capabilities of a mobile communication Network to third parties.

In the present application, "plurality" means two or more; "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the present application, the execution sequence of the steps in each embodiment is not strictly limited, and may be exchanged or adjusted.

In the present application, the related messages may be implemented in a servitization manner, that is, the related messages may be replaced by corresponding servitization messages, which is not limited.

It is to be noted that the exemplifications mentioned in the present application do not represent an optimum; the first, second and the like mentioned in the present application are only used for distinguishing different information, messages or other objects, and do not represent a sequential relationship; in addition, the embodiments in the present application may refer to and use for reference, and the same or similar steps or terms are not repeated.

As shown in fig. 3, a communication method provided in the first embodiment of the present application is as follows.

301. The priority management device receives a priority request message from the traffic server.

The priority request message carries identification information of an object (object), which may include a call or a user. The call may be a call serviced by the service server, and the user may be a user serviced by the service server, without limitation.

Wherein the priority of the object may represent the priority of the allocation and/or maintenance of network transmission resources by the object.

In particular, when the object is a call, the priority of the call represents the priority of the call on the allocation and/or maintenance of network transmission resources. For example, the priority of the call a is higher than that of the call B, and when the network transmission resource is limited, if the service server receives the establishment requests of the call a and the call B at the same time, the service server will preferentially ensure that the call a can acquire the network transmission resource through the corresponding priority, which may be specifically implemented in a manner of rejecting the establishment request of the call B. For another example, assuming that call a and call B have been successfully established, if the network is congested, the service server will release call B so as to release the network transmission resource, thereby ensuring that call a can still use the network transmission resource.

When the object is a user, the priority of the user may represent the priority of the user's allocation and/or maintenance of network transmission resources. For example, the priority of the user a is higher than that of the user B, and when the network transmission resource is limited, if the service server receives the call requests of the user a and the user B at the same time, the service server preferentially ensures that the user a can acquire the network transmission resource, specifically by rejecting the call request of the user B. For another example, after the user a and the user B have joined the call to obtain the network transmission resource, if the network is congested, the service server will release part or all of the call of the user B, so as to release the network transmission resource, thereby ensuring that the user a still uses the network transmission resource.

Wherein, the priority request message can be used for requesting arbitration, determination, modification, promotion or sequencing of the priority of the object; the priority request message may also carry an expected priority of the object and/or priority reference information of the object. When the priority request message carries identification information of an object and a desired priority of the object, the priority request message may be used to request authorization (grant) of the object to use the desired priority.

Specifically, the priority request message may be an urgent task priority request (MC priority request); other message names are also possible, such as priority modification requests, priority promotion requests, and the like, and the names of the messages are not limited herein.

In addition, the identification information of the object carried in the priority request message may include identification information of one or more objects, and the priority request message may be in the form of an identification information list of the object.

The identification information of the object may be used to identify the object, and may be identification information of a user or identification information of a call, for example.

Specifically, the identification information of the call is used to identify the call, and may be a string of character combinations including letters, numbers and special symbols; the identifier of the call may also be the Session identifier (Session ID) of the call; but also an identification of a group call, or an identification of a private call (private call); may also be an identification of a group; the identification information of the call may include identification information of the user and identification of the call, or may include identification of the call and a service type, such as GroupA + MCPTT, or may include a combination of a calling identification and a called identification, such as calling user a ID + called user b ID, or may include a combination of the calling identification, the called identification, and the service type. Private calls may also be referred to herein as single calls.

Specifically, the identification information of the user is used to identify the user, and may be a string of character combinations that may include alphanumeric and special symbols, such as Session initiation Protocol uniform resource Locator (SIP URL), or Mobile station international ISDN number (MSISDN), i.e. the telephone number of the Mobile user, or an IP address.

When the object is a call, the priority reference information of the object is the priority reference information of the call, and may include at least one of the following: network area information, service type of the call, communication type of the call, priority of the call, role of the user corresponding to the call, and location information of the user corresponding to the call.

The network area information may be used to identify a network area, and specifically may be identification information of a Cell, for example, a Cell ID, identification information of a base station (for example, a name of the base station, an ID of the base station), a Tracking Area Identifier (TAI), a Cell identifier List (Cell List), a tracking area identifier List (TAI List), an identifier List of the base station, an identifier List (SAI List) of a Service Area Identifier (SAI), or a geographic coordinate.

It should be noted that, when the priority reference information includes the network area information, the priority request message may be used to request arbitration, determination, modification, promotion, or sequencing of the priority of the object in the network area corresponding to the network area information; further, when the priority request message may also carry the desired priority of the object, the priority request message may be used to request authorization for the object to use the desired priority in a network area corresponding to the network area information. The network area corresponding to the network area information may be a network area identified by the network area information, for example, a cell identified by a cell ID, or a network area covered by a base station identified by the identification information of the base station.

The service type of a call may refer to the type of service to which the call corresponds, e.g., MCPTT, MCVideo, or MCData.

The communication type of the call can be a group call, an emergency group call, a single call, or an emergency single call.

The role of the user corresponding to the call can be a dispatcher, a field commander, a common policeman and the like.

The location information of the user corresponding to the call is used to indicate the location of the user corresponding to the call, and may be identification information of a cell in which the user is located or identification information of a base station in which the user is located.

The user corresponding to the call may be the user who is making the call, or the user who initiates the call.

When the object is a user, the priority reference information of the object is the priority reference information of the user, and may include at least one of the following: network area information, service priority of the user, group priority of the user, role of the user, location information of the user and communication state information of the user.

For the network area information, reference may be made to the above related description, which is not described in detail.

The service priority of a user is used to indicate the priority of the user in a certain service type.

The group priority of the user refers to the priority of the user in the group to which the user belongs, and if the group configuration supports multiple service types, the group priority of the user may also indicate the priority of the user in a certain service type in the group.

The user can be a dispatcher, a field commander, a common policeman or the like.

The communication status information of the user may include: identification information of a call corresponding to a user, a service type of the call corresponding to the user, and a communication type of the call corresponding to the user.

The call corresponding to the user may refer to a call served by the service server in an ongoing call of the user. The service type of the call corresponding to the user may refer to the service type of the call, the communication type of the call corresponding to the user may refer to the communication type of the call, and the identification information of the call corresponding to the user may refer to the identification information of the call, which is not described in detail. In addition, the call corresponding to the user may be a part of the call of the user, or may be all the calls of the user.

The location information of the user is used to indicate the location of the user, and may specifically be identification information of a cell where the user is located, or identification information of a base station where the user is located, or the like.

302. And the priority management equipment determines the priority of the object according to the priority request message.

The priority may be absolute priority, that is, each priority corresponds to a specific numerical value, and one or more objects may use the same priority at the same time, for example, the priority of object a is 23; it may also be a relative priority, i.e. representing a relative priority ordering between an object and another object or objects, or representing a relative priority ordering of an object in a preset network area, for example, 1 st of the inverse of the priorities of all objects located in the preset network area from high to low, or further for example, the priorities of all objects located in the preset network area from high to low are divided into priority levels in groups of 5, and the priority level of the object a is the first-to-last level.

The priority request message may serve as a trigger condition of step 302, for example, the priority management device executes an action of determining the priority of the object after receiving the priority request message, or may serve as a basis for determining the priority of the object, for example, information carried in the priority request message is used as a basis for determining the priority of the object. Of course, the priority request message may also have the above two functions at the same time, without limitation.

In a first example, the priority request message further carries priority reference information of the object, and step 302 may be: the priority management device determines the priority of the object according to the priority reference information of the object.

The determining of the priority of the object according to the priority reference information of the object may be implemented as follows.

The first mode and the sequential ordering method are as follows: and sequentially carrying out priority ordering according to different information in the priority reference information.

Taking an object as an example of a call, assuming that the priority request message carries priority reference information of 14 calls, and 14 calls may be numbered as call 1, 2, …,14, the priority management device may first prioritize the 14 calls according to call types, for example, emergency single call (1, call 1) > emergency group call (1, call 2) > ordinary single call (10, call 3, 4, …, 12) > ordinary group call (2, call 13,14), where emergency single call > emergency group call indicates that the priority of the emergency single call is higher than that of the emergency group call, and ordinary single call (10, call 3, 4, …, 12) indicates that 10 ordinary single calls exist in the 14 calls, and number of the calls is call 3, 4, …, 12; then, the priority management device sorts the calls of different call types according to the service types, for example, the result of sorting 10 calls of a common single call according to the service types is: MCPTT (1, call 3) > MCVideo (1, call 4) > MCData (7, call 5, 6, …, 12), where MCPTT > MCVideo indicates that MCPTT has a higher priority than MCVideo, and the result of the priority ranking for a normal group call is: MCPTT (1, call 13) > MCVideo (1, call 14); furthermore, calls of different service types can be sorted according to other priority reference information, for example, the roles of users, 7 calls of MCData and sorted, so as to obtain the priorities of objects, for example, call 1> call 2> call 3> call 4> call 5, 6, …, 12> call 13> call 14.

The second method and the weight calculation method are as follows: and assigning a weight to each piece of information in the priority reference information, calculating a priority value of the object according to the weight, and determining the priority of the object according to the calculation result.

Specifically, each priority reference information is used as an input parameter of a priority algorithm, each priority reference information is given a weight, and then a priority value is calculated according to the priority algorithm and the weight, wherein the priority algorithm can beIndicating that the products of n parameters and the weights thereof are added to obtain the priority value of the object, wherein Pi represents the parameters, each parameter is assigned a certain value, and Wi represents the weight value of Pi. A larger result of the calculation may indicate a higher priority,

further, the priority management device may perform priority ordering according to the calculation result to determine the priority of the object, or may compare the calculation result with a preset threshold to determine the priority of the object. For example, if the calculation result is higher than the first threshold, the priority of the object is the 1 st priority; and if the calculation result is higher than the second threshold and lower than the first threshold, the priority of the object is the 2 nd priority. The 1 st priority is higher than the 2 nd priority.

It should be noted that, when the priority reference information includes the network area information, the priority request message may be used to request the priority of the object in the network area corresponding to the network area information. Accordingly, the determining the priority of the object according to the priority reference information of the object may be: and determining the priority of the object in the network area corresponding to the network area information according to the priority reference information of the object. For example, the priority request message carries identification information of the object 1 and network area information, where the network area information is a cell ID, and a cell identified by the cell ID includes an object 2 and an object 3 in addition to the object 1; the priority management device may refer to the first manner, and perform priority ordering on the three objects, where the priority is from top to bottom: object 3> object 1> object 2, then the priority of object 2 may be 3 rd priority.

In a second example, the method further comprises: the priority management device obtains communication state information of the network area. Step 302 may be: the priority management device determines the priority of the object according to the obtained communication state information.

Wherein, the communication status information may include: identification information of an object within the network area, and communication status information of the object, e.g., communication status information of a call within the network area and/or communication status information of a user within the network area. Specifically, the communication state information of the call may include: at least one of a service type, a communication type of a call, a priority of the call, a role of a user corresponding to the call, and location information of the user corresponding to the call; the communication status information of the user may include: at least one of the service priority of the user, the role of the user, the location information of the user, and the communication status information of the user, and the related description may refer to the related description in step 301, which is not described again.

The network area may be a network area corresponding to the network area information in the priority reference information, or a network area determined by the priority management device according to the location of the object identified by the identification information of the object in the priority request message, for example, a service area of the service server, or a network area managed by the priority management device, or a network area in which congestion occurs, without limitation. Specifically, the network area managed by the priority management device may mean that the priorities of the objects in the network area are all managed by the priority management device.

Specifically, the priority management device may prioritize all objects in the network area according to the communication state information, thereby obtaining the priority of the object in the priority request message. Since the communication status information is similar to the parameters of the priority reference information, the priority management device may refer to the related description in the first example for determining the priority of the object according to the obtained communication status information, and details are not repeated.

The priority management device may obtain the communication status information of the network area before step 301, or may obtain the communication status information of the network area after step 301 and before step 302, without limitation. The specific implementation manner of this may refer to the related description of step 701, which is not described again.

Optionally, the priority of the object is determined in the second example as follows: the priority management device determines the priority of the object in the network area corresponding to the network area information, which may specifically refer to the description in the first example and is not described again.

In a third example, the method further comprises: the priority management device obtains communication state information of the network area.

Wherein, when the priority request message further carries the priority reference information of the object, step 302 may specifically be: the priority management device determines the priority of the object based on the priority reference information of the object and the obtained communication state information.

The priority management device may obtain the communication state information of the network area, and the network area and the like may refer to the related description in the second example, which is not described again.

Wherein, the communication state information of the network area may be provided by other service servers except the service server which transmits the priority request message, and the communication state information of the network area includes communication state information of objects which are located in the network area and are provided with services by the service server. For example, the service server 1 transmits the above-described priority request message, and the priority management device obtains the communication state information of the network area provided by the service servers 2 and 3, the communication state information of the network area including all or part of the objects provided with the service by the service server 2 in the network area and all or part of the objects provided with the service by the service server 3 in the network area.

Specifically, the priority management device may perform priority ranking on the object and the object related in the communication state information of the network area according to the priority reference information of the object and the obtained communication state information, which may specifically adopt the manner in the first example and is not described again.

Optionally, the priority of the determination object in the third example is: the priority management device determines the priority of the object in the network area corresponding to the network area information, which may refer to the above description and is not described again.

In the method provided by the above embodiment, the priority management device receives the priority request message from the service server, where the priority request message carries identification information of a call or a user, and determines the priority of the call or the user according to the priority request message, and the priority of the call or the user can be used for allocating or maintaining transmission resources of the mobile communication network, so that the call or the user can more reasonably and more flexibly use the transmission resources of the mobile communication network, and especially, when the mobile communication network is congested, the call or the user can be released by the low priority of the call or the user to alleviate network congestion.

Optionally, in the first scenario of the foregoing embodiment, the identification information of the object carried by the priority request message includes identification information of N objects, where N is a positive integer; the determining the priority of the object in step 302 may specifically be: the priority management device determines the priorities of the N objects.

The N objects may be objects that the service server desires to release, and may be determined by the service server according to a preset rule, for example, the N objects may be objects whose priorities are N lower among the objects served by the service server.

Specifically, the service server may rank the objects served by the service server from high to low or from low to high in priority, and carry the identification information of the objects with the lower priority of N in the priority request message.

It should be noted that the priority being in the lower N refers to the last N in the order of priority from high to low, or the first N in the order of priority from low to high.

Assuming that the number of the objects with the lowest priority is greater than N, N objects can be randomly selected from the objects with the lowest priority to be carried in the priority request message; assuming that the number of objects of the lowest priority is less than N, for example, the number of objects of the lowest priority is M, (N-M) objects may be selected among objects of the next lowest priority, and further, if the number of objects of the next lowest priority is less than (N-M), I, (N-M-I) users may be selected among objects of the next lowest priority. The following description will be given by taking the low-to-high priority ranking as an example:

the number of 1 st priority (i.e., lowest priority) objects is X, and X < N; the number of objects of the second priority (i.e., the second lowest priority) is Y, and (X + Y) < N; if the number of objects with the third priority (the second lowest priority) is Z and (X + Y + Z) > N, the priority request message carries the identification information of all objects with the 1 st priority and the 2 nd priority, and the identification information of (N-X-Y) objects with the 3 rd priority.

It should be noted that the first scenario can be combined with the three examples in step 302, and is not limited.

In the first implementation scenario, the service server provides the identification information of the objects with the priorities lower than N, so that the priority management device determines the priorities more specifically, the complexity of the priority management device is reduced, the processing time is saved, the objects to be released can be further determined in time according to the priority information, and the problem of network congestion is solved in time.

Optionally, in a second scenario of the foregoing embodiment, after step 302, the method may further include:

the priority management device determines the object to be released according to the priority determined in step 302, and instructs the service server corresponding to the object to be released to release the object to be released.

The object to be released may be a call or a user, where releasing the call may refer to releasing the resources occupied by the call, that is, the service server terminates the call, all users participating in the call leave the call, and the network transmission resources related to the call of all users participating in the call are released. Releasing a user may refer to releasing resources occupied by a call of the user, specifically, releasing resources occupied by all calls of the user, and also releasing resources occupied by a part of calls of the user, without limitation.

Specifically, when the service server corresponding to the object to be released exists in the service server in step 301, the priority management device may send a priority response (priority response) message to the service server in step 301, where the priority response message may be used to indicate to release the object to be released that is served by the service server, and for example, the priority response message may carry identification information of the object to be released that is served by the service server. Optionally, other messages are used to instruct the service server to release the object to be released served by the service server, for example, a release request message, a release notification message, a priority release message, etc., without limitation.

It should be noted that, when the object to be released is a user, the priority response message may also carry identification information of a call of the user, and at this time, the priority response message may be used to indicate that the call of the user and identified by the identification information of the call is released. When the object to be released is a user, the priority response message may not carry identification information of the call of the user, and at this time, the priority response message may be used to indicate that all calls of the user, which are served by the service server, are released.

Specifically, when there is another service server other than the service server in step 301, the priority management device may send a notification message (e.g., an MCpriority notification) to the other service server to instruct or notify the other server to release the object to be released, which is served by the other service server. When the notification message is used to instruct or notify other servers to release the user to be released, which is served by other service servers, the notification message may also carry identification information of the call of the user, and at this time, the notification message may be used to notify or instruct to release the call of the user and identified by the identification information of the call. When the notification message is used to instruct or notify other servers to release the user to be released, which is served by other service servers, the notification message may not carry identification information of the call of the user, and at this time, the notification message may be used to notify or instruct to release all calls of the user, which are served by the service server that receives the notification message.

The determination, by the priority management device, of the object to be released according to the priority determined in step 302 may specifically be: and determining the objects with the priority levels lower than M or the objects with the priority levels lower than the preset threshold as the objects to be released, without limitation.

It should be noted that the second scenario may also be combined with the first scenario of the above embodiment, and is not limited.

In the second implementation scenario, the priority management device determines the object to be released according to the priority, so that the reasonable use of the transmission resource is realized.

Optionally, in a third scenario of the foregoing embodiment, the priority request message further carries an expected priority of the object, and at this time, the priority request message may be used to request that the object is authorized to request to use the expected priority.

The desired priority may be a target priority of the object, and therefore the desired priority may also be referred to as a target priority without limitation.

The determining the priority of the object in step 302 may specifically be: the priority of the object is determined to be the desired priority.

Further, after the step 302, the method may further include: the priority management device indicates to the service server that the object is authorized to use the desired priority.

Specifically, the priority management device may transmit a priority response message to the service server, the priority response message indicating that the object is authorized to use the desired priority. For example, the priority response message may carry authorization indication information, where the authorization indication information is used to indicate that the object is authorized to use the desired priority. The priority management device may also send a priority granted (priority granted) message, for example, MC priority granted, to the service server.

Further, the method further comprises: the priority management device indicates to the other traffic servers that the desired priority is occupied.

Specifically, the priority management device may send a priority taken (token) message, for example, an MC priority token, to the other traffic server, where the priority taken message is used to indicate that the desired priority is taken. For example, the priority occupancy message contains the desired priority, the network area to which the desired priority applies, and the identification information of the above-mentioned object.

Wherein, other service servers can provide service for the network area, and the service servers are other than the service server.

Optionally, in an alternative of the third scenario, the determining the priority of the object in step 302 may specifically be: it is determined that the priority of the object is not the desired priority.

Further, after the step 302, the method may further include: the priority management device indicates to the service server that the object is denied use of the desired priority.

Specifically, the priority management device may transmit a priority response message to the service server, the priority response message indicating that the object is rejected from using the desired priority. For example, the priority response message may carry rejection indication information, where the rejection indication information is used to indicate that the object is rejected to use the desired priority. Further, the priority response message may also carry a reason value for rejection. The priority management device may also send a priority reject message, e.g., MC priority rejected, to the service server.

It should be noted that, the priority response message may simultaneously carry authorization indication information and rejection indication information for different objects, which is not limited.

Furthermore, this third scenario can be combined with the three examples in step 302, without limitation.

The third implementation scenario described above realizes dynamic adjustment of the priority of the user or the call according to the requirement, and can provide the transmission service of the mobile communication network for the call or the user more specifically, for example, allocate or maintain the transmission resource, thereby realizing reasonable use of the transmission resource.

As shown in fig. 4A, a communication method provided in the second embodiment of the present application is as follows.

401a, the service server sends a priority request message to the priority management device.

The priority request message carries identification information of an object and a desired priority of the object, wherein the object may include a call or a user.

The priority request message may also carry priority reference information of the object.

402a, the service server receives a priority response message from the priority management device.

Wherein the priority response message is used to indicate that the object is authorized to use the desired priority.

It should be noted that, the priority request message, the priority reference information, the expected priority, and the like may all refer to the relevant description in the embodiment shown in fig. 3, and are not described again.

Optionally, in an implementation scenario of the foregoing embodiment, before step 401a, the method further includes:

the service server receives a trigger message from the client;

and the service server sends the priority request message to the priority management equipment according to the trigger message.

The client may be a terminal device, or may be an Application (APP) on the terminal device.

The trigger message may also carry an expected priority of the object and/or priority reference information of the object, and may also carry related information of the authorized user, for example, identification information of the authorized user, and may also include a role of the authorized user, or a priority of the authorized user, which may be referred to in the above embodiments for related descriptions of the identification information of the user, the role of the user, and the priority of the user, and is not described again.

Specifically, the information related to the authorized user may be used to verify the authority of the authorized user by the service server, and if the authority of the authorized user passes the verification, the priority request message may be sent to the priority management device.

When the trigger message carries the identification information of the object and the expected priority of the object, the trigger message may be specifically used to trigger the service server to send a priority request message to the priority management device, where the priority request message may carry the identification information of the object and the expected priority of the object, so as to request the priority management device to authorize the object to use the expected priority.

When the trigger message does not carry the expected priority of the object, the method may further include: and the business server determines the expected priority of the object according to a preset rule. For example, a correspondence between the identification information of the object and the expected priority of the object is stored, and the service server determines the expected priority of the object according to the correspondence.

It should be noted that the trigger message may be the same as or different from the priority request message in step 401a, for example, the service server receives two trigger messages, where the trigger message 1 carries the identification information of the object 1 and the expected priority of the object 1, and the trigger message 2 carries the identification information of the object 2 and the expected priority of the object 2, so that the priority request message may carry the identification information of the object 1 and the expected priority of the object 1, and the identification information of the object 2 and the expected priority of the object 2.

In the method provided in the foregoing embodiment, the service server sends the priority request message to the priority management device, where the priority request message carries the identification information of the object and the expected priority of the object, and receives the priority response message from the priority management device, so that the dynamic adjustment of the priority of the user or the call is implemented, and the adjustment of the priority is more flexible, and thus, the transmission service of the mobile communication network can be provided for the call or the user more specifically, for example, transmission resources are allocated or maintained, and reasonable use of the transmission resources is implemented.

As shown in fig. 4B, a communication method provided in the third embodiment of the present application is as follows.

401b, the service server sends a priority request message to the priority management device.

The priority request message carries identification information of N objects, wherein N is a positive integer. N objects, which may be objects that the service server desires to release, may be represented in a list form in the priority request message.

Specifically, the N objects may be the objects whose priorities are located in the lower N of the objects providing services in the service server, and refer to the relevant description in the embodiment shown in fig. 3, which is not described again.

Optionally, the priority request message further carries priority reference information of the N objects.

402b, the service server receives the identification information of the object to be released from the priority management device.

Wherein, the identification information of the object to be released may be carried in the priority response message.

Specifically, the priority response message may carry identification information of the user to be released and an identification of the call of the user, and at this time, the service server may release the call of the user according to the priority response message.

The priority response message may also carry identification information of a user to be released, but does not carry identification information of a call of the user, at this time, the service server may release all calls of the user and provided with services by the service server, which may refer to related descriptions in the embodiment shown in fig. 3 and will not be described again.

403b, the service server releases the object to be released according to the identification information of the object to be released.

Optionally, step 401b is preceded by: the service server performs priority ranking on the objects providing the service (for example, the service server may refer to information according to the priorities of the objects), and carries identification information of the objects with the lower N priorities in the priority ranking in a priority request message and sends the priority request message to the priority management device.

For example, when the service server corresponding to the object to be released does not include the service server in step 401b, step 402b may be replaced by receiving a priority response message, but the response message may not carry the identification information of the object to be released, and for example, when the service server corresponding to the object to be released does not include the service server in step 401b, steps 402b and 403b may not be executed.

In the method provided by the above embodiment, the service server provides N low-priority objects, which can save processing time of the priority management device, so that the priority management device can more quickly determine the object to be released, and the service server solves the problem of network congestion by releasing the object to be released.

Optionally, in an implementation scenario of the foregoing embodiment, before step 401b, the method further includes:

the service server receives a trigger message from the client or the mobile communication network equipment; and sending the priority request message to the priority management device according to the trigger message.

The mobile communication network device may be an SCEF or a NEF.

In addition, the trigger message may carry network area information.

When the trigger message is from a mobile communication network device, the trigger message may be used to inform that congestion has occurred, or to inform the network area where congestion has occurred. Specifically, the trigger message may carry network area information, where the network area information is used to identify a network area, the network area may be a network area where congestion occurs, and the trigger message may be a congestion notification message, which is not limited.

When the trigger message comes from the client, the trigger message may be used to trigger the service server to send a priority request message to the priority management device, so as to request the priority management device to modify, promote, or sort the priority of the object.

Specifically, the trigger message may carry identification information of the object. Further, the trigger message may also carry an expected priority of the object and/or priority reference information of the object, and may also carry related information of the authorized user, for example, identification information of the authorized user, and may also include a role of the authorized user, or a priority of the authorized user, which may refer to related descriptions of the identification information of the user, the role of the user, and the priority of the user in the above embodiments, and are not described again. The information related to the authorized user can be used for the service server to verify the authority of the authorized user, and if the verification is passed, the priority request message can be sent to the priority management device.

When the trigger information carries the identification information of the object and the expected priority of the object, the trigger information may be specifically used to trigger the service server to send a priority request message to the priority management device, where the priority request message may carry the identification information of the object and the expected priority of the object, so as to request the priority management device to authorize the object to use the expected priority.

Optionally, in another implementation scenario of the foregoing embodiment, before step 401b, the method further includes: and the service server determines the N objects according to a preset rule.

In particular, a business server may prioritize objects served by the business server and located within a network region. The network area may be an area corresponding to the network area information carried by the trigger message, or may be a preset area, which is not limited.

Optionally, the priority request message carries communication status information of the network area, and specifically, the communication status information of the network area may include communication status information of a call located in the network area and served by the service server and/or communication status information of a user.

It should be noted that the trigger message may be the same as or different from the priority request message in step 401b, and refer to the related description in the embodiment shown in fig. 4A, which is not described again.

As shown in fig. 4C, a communication method provided in the fourth embodiment of the present application is as follows.

401c, the service server sends a priority request message to the priority management device.

The priority request message carries identification information of N objects, wherein N is a positive integer. N objects, which may be objects that the service server desires to retain, may be represented in a list form in the priority request message.

Specifically, the N objects may be objects whose priorities are higher than N among the objects serviced by the service server.

402c, the service server receives the identification information of the object to be reserved from the priority management device.

The object to be reserved may be a call or a user, and reserving a call may refer to reserving resources occupied by the call, that is, the service server applies for network transmission resources for the call or reserves occupied network transmission resources. The reservation of the network transmission resources for the call of the user may be performed by the service server, or the occupied network transmission resources may be reserved, specifically, the network transmission resources for all the calls of the user may be applied or the occupied network transmission resources may be reserved, or a part of the network transmission resources for the call of the user may be reserved or the occupied network transmission resources may be reserved, without limitation.

Specifically, when the service server corresponding to the object to be reserved exists in the service server in step 401c, the priority management device may send a priority response (priority response) message to the service server in step 401c, where the priority response message may be used to indicate that the object to be reserved, which is served by the service server, is reserved, and for example, the priority response message may carry identification information of the object to be reserved, which is served by the service server. Optionally, other messages are used to instruct the service server to reserve the object to be reserved, which is served by the service server, such as a reservation request message, a reservation notification message, a priority release message, and the like, without limitation.

It should be noted that, when the object to be reserved is a user, the priority response message may also carry identification information of a call of the user, and at this time, the priority response message may be used to indicate that the call of the user and identified by the identification information of the call is reserved. When the object to be reserved is a user, the priority response message may not carry identification information of a call of the user, and at this time, the priority response message may be used to indicate that all calls of the user, which are served by the service server, are reserved.

It should be noted that steps 402c and 403c are optional steps, for example, when the service server corresponding to the object to be reserved does not include the service server in step 401c, step 402c may be replaced by receiving a priority response message, but the response message may not carry the identification information of the object to be reserved, and step 403c is not executed; for another example, when the service server corresponding to the object to be retained does not include the service server in step 401c, steps 402c and 403c are not performed.

403c, the service server reserves the object to be reserved according to the identification information of the object to be reserved.

Specifically, step 403c may release other objects than the object to be retained from the N objects.

In the method provided by the embodiment, the service server provides N high-priority objects, so that the time for the priority management device to determine the priority can be saved, the priority management device can determine the object to be reserved more quickly, and the service server can reserve the object to be reserved, thereby solving the problem of network congestion.

Optionally, in an implementation scenario of the foregoing embodiment, before step 401c, the method further includes:

The mobile communication network device may be an SCEF or a NEF.

In addition, the trigger message may carry network area information.

Specifically, the trigger message may carry identification information of the object. Further, the trigger message may also carry priority reference information of the object, and may also carry related information of the authorized user, for example, identification information of the authorized user, and may also include a role of the authorized user, or a priority of the authorized user, which may refer to related descriptions of the identification information of the user, the role of the user, and the priority of the user in the above embodiments, and will not be described again. The information related to the authorized user can be used for the service server to verify the authority of the authorized user, and if the verification is passed, the priority request message can be sent to the priority management device.

It should be noted that the trigger message may be the same as or different from the priority request message in step 401c, and refer to the related description in the embodiment shown in fig. 4A, which is not described again.

In another implementation scenario of the foregoing embodiment, before step 401c, the method further includes: and the service server determines the N objects according to a preset rule.

Specifically, the service server may rank the objects served by the service server from high to low or from low to high in priority, and carry the identification information of the objects with the highest N priorities in the priority request message.

It should be noted that the priority being at the top N refers to the top N in the order of priority from high to low, or the bottom N in the order of priority from low to high.

Assuming that the number of the objects with the highest priority is greater than N, N objects can be randomly selected from the objects with the highest priority to be carried in the priority request message; assuming that the number of objects of the highest priority is less than N, for example, the number of objects of the highest priority is M, (N-M) objects may be selected among objects of the next highest priority, and further, if the number of objects of the next highest priority is less than (N-M), I, (N-M-I) users may be selected among objects of the next highest priority. The following description will be given by taking the low-to-high priority ranking as an example:

the number of 1 st priority (i.e., highest priority) objects is X, and X < N; the number of objects of the second priority (i.e., the second highest priority) is Y, and (X + Y) < N; if the number of objects with the third priority (the second highest priority) is Z and (X + Y + Z) > N, the priority request message carries the identification information of all objects with the 1 st priority and the 2 nd priority, and the identification information of (N-X-Y) objects with the 3 rd priority.

In the method provided by the embodiment, the client obtains the identification information of the object and the expected priority of the object, and sends the trigger message to the service server, so that the flow of the client triggering the priority adjustment or sequencing is realized, and the method is more flexible.

As shown in fig. 6, a sixth embodiment of the present application provides a communication method, as described below.

601. The service server receives the identification information of the object to be released from the priority management equipment.

602. And the service server releases the object to be released according to the identification information of the object to be released.

In addition, when the object to be released is a user, the priority response message may further include an identifier of a call of the user, and further, step 602 may specifically be to release the call of the user; when the object to be released is a user and the priority response message does not include the identifier of the call of the user, step 602 may specifically be to release all calls of the user and served by the service server.

In the method provided by the above embodiment, the service server releases the call or the user according to the identification information of the user or the call to be released, which is provided by the priority management device, so that the problem of network congestion is solved.

601a, the service server receives the identification information of the object to be reserved from the priority management device.

602a, the service server reserves the object to be reserved according to the identification information of the object to be reserved.

Specifically, step 602a may be releasing other objects than the object to be retained.

The identification information of the object to be retained may be carried in the priority response message.

In addition, when the object to be reserved is a user, the priority response message may further include an identifier of a call of the user, and further, step 602a may specifically be to reserve the call of the user; when the object to be reserved is a subscriber and the priority response message does not include the identifier of the call of the subscriber, step 602a may specifically be to reserve all calls of the subscriber and served by the service server.

In the method provided by the above embodiment, the service server may release the transmission resource according to the to-be-reserved call or the user identifier information provided by the priority management device, so as to solve the problem of network congestion.

As shown in fig. 7, an eighth embodiment of the present application provides a communication method, as described below.

701. The priority management device obtains communication state information of the network area.

The communication state information in step 701 may include communication state information of a network area provided by one or more service servers, in other words, communication state information of an object served by one or more service servers.

702. The priority management device determines the priority of the object according to the obtained communication state information.

In addition, the communication status information, priority, object, and step 702 of the network area may all refer to the related description in the embodiment shown in fig. 3, and are not described again.

Optionally, before step 701, or after step 701 and before step 702, further comprising: the priority management device receives a trigger message from a client or a mobile communication network device.

The mobile communication network device may be an SCEF or an NEF.

When the trigger message comes from the mobile communication network device, the trigger message may be used to notify that congestion occurs, and the trigger message may carry network area information, which may be used to identify the network area in step 701. In particular, the trigger message may be a congestion notification message.

The information related to the authorized user includes identification information of the authorized user, and may further include a role of the authorized user, or a priority of the authorized user, for example, a service priority. The information related to the authorized user may be used to verify the authority of the authorized user by the priority management device, and if the verification passes, step 702 is executed.

Specifically, step 701 may adopt the following three implementation manners:

in a first mode, the priority management device sends a communication status request (traffic status request) message to a service server providing service for a network area, and receives a communication status response message from the service server, where the communication status response message carries the communication status information.

The service server providing services for the network area may include all or part of the service servers providing services for the network area, without limitation.

The communication status request message may include a priority type (priority type), a status type (status type), or the number of objects, among others.

In particular, the priority type may be used to indicate a type of requesting priority, and may be used to indicate a priority type of an object requested by the priority management device, for example, whether the object requesting the highest priority or the object requesting the lowest priority; the status type may be a type of object, may be used to indicate whether the object requested by the priority management device is a call or a user, or both; the number of objects may be used to indicate the number of objects requested by the priority management device.

In one example, the communication status request message is used to request communication status information of objects whose priority is lower than N among objects served by the service server. Specifically, the communication status request message includes a priority type of the lowest priority and the number of objects is N. Wherein N is a positive integer.

In another example, the communication status request message is used to request communication status information of an object whose priority is higher than N among objects served by the service server. Specifically, the communication status request message includes a priority type of the highest priority and the number of objects is N. Wherein N is a positive integer.

In the second mode, the priority management device sends a communication status subscription message (MC traffic status request) to a service server providing services for the network area, and receives a communication status notification message (MC traffic status notification) from the service server, where the communication status notification message carries communication status information of the network area.

The communication state subscription message may be used to subscribe to the communication state information of the service server network area.

In one example, the communication state subscription message is used to subscribe to object communication state information whose priority is lower than N in an object serviced by the service server. Wherein N is a positive integer.

In another example, the communication state subscription message is used to subscribe to object communication state information whose priority is N higher among objects served by the service server. Wherein N is a positive integer.

And thirdly, the priority management equipment receives a communication state report from a service server providing service for the network area, wherein the communication state report carries the communication state information of the network area.

The communication state information mentioned in the above three ways may include identification information of N objects and communication state information of the N objects. The N objects may be objects whose priorities are lower than N or objects whose priorities are higher than N among the objects of the service provided by the service server, where N is a positive integer, and reference may be made to the related description in the above embodiments, which is not described again.

In the method provided by the above embodiment, the priority management device determines the priority of the call or the user according to the communication state information of the network area, so that the dynamic adjustment of the priority of the user or the call is realized, the adjustment of the priority is more flexible, and further, the transmission service of the mobile communication network can be provided for the call or the user more specifically, for example, transmission resources are allocated or maintained, and the reasonable use of the transmission resources is realized.

Optionally, in an implementation scenario of the foregoing embodiment, after step 702, the method further includes: and the priority management equipment determines the object to be released according to the priority of the object and indicates a service server corresponding to the object to be released to release the object to be released.

Wherein, the identification information of the object to be released may be carried in the priority request message.

Further, the method may further include: and receiving a priority response message from the service server, wherein the response message can be used for responding to the priority request message and can also be used for indicating the successful release of the object.

The determination, by the priority management device, of the object to be released according to the priority determined in step 702 may specifically be: and determining the objects with the priority levels lower than N or the objects with the priority levels lower than the preset threshold as the objects to be released, without limitation.

Optionally, in another implementation scenario of the foregoing embodiment, after step 702, the method further includes: and the priority management equipment determines the object to be reserved according to the priority of the object and indicates a service server corresponding to the object to be reserved to reserve the object to be reserved.

The determination, by the priority management device, of the object to be released according to the priority determined in step 302 may specifically be: and determining the objects with the priorities at the top of M or the objects with the priorities higher than a preset threshold as the objects to be reserved without limitation.

Further, the method may further include: and receiving a priority response message from the service server, wherein the response message can be used for responding the priority request message and indicating the object retention is successful.

As shown in fig. 8, a ninth embodiment of the present application provides a communication method, as follows.

801. The client sends a first priority request message to the first service server.

Wherein the first priority request message includes identification information of the object and a desired priority of the object, and may further include related information of an authorized user or priority reference information of the object.

In particular, an authorized user may trigger an adjustment of the priority of an object through an interface with the client, e.g., an APP. The authorized user may be a dispatcher or an administrator, and the related information of the authorized user may refer to the related description in the embodiment shown in fig. 3, which is not described again.

802. And the first service server sends a second priority request message to the priority management equipment.

The second priority request message carries identification information of the object and a desired priority of the object, and is used for requesting authorization of the object to use the desired priority. The second priority request message may be the same as or different from the first priority request message, for example, the second priority request message may be generated according to a parameter carried in the first request message, for example, the first priority request message may be generated according to a plurality of second priority request messages.

803. And the priority management equipment sends a communication state request message to the second service server.

When the message carries the priority type, the communication status response message may carry a communication status of the call or a communication status of the user.

When the communication status request message carries the status type, the communication status response message may carry a set of objects ordered from high to low priority, or a set of objects ordered from low to high priority.

When the communication status request message carries the number of the objects, the communication status response message may carry the communication status information of the objects, and the number of the objects is not greater than the number carried in the communication status request message.

When the message does not carry any of the parameters, the communication state response message carries the communication state information of all the objects provided with the service by the second service server.

The communication state information of the object may be communication state information of a call or communication state information of a user, which may refer to the related description in the above embodiments and is not described again.

The communication status request message in step 803 may be replaced by a communication status subscription message MC traffic status request, and correspondingly, the communication status response message in step 804 may be replaced by a communication status notification message MC traffic status notify; alternatively, steps 803 and 804 may be replaced by receiving a communication status report, where the communication status report carries communication status information of a network area, which may refer to the related description of step 701 and is not described again.

It should be noted that step 803-. In addition, the execution sequence between steps 801-804 may be adjusted, for example, steps 803-804 may be executed before step 801, without limitation.

805. The priority management device determines the priority of the object.

Step 805 may be: the priority management device determines whether the priority of the object is a desired priority.

Specifically, the priority management device may determine according to the second priority request message in step 802 and the communication status response message in step 804, or the priority management device may determine according to the stored communication status information of the network area after receiving the second priority request message, which may refer to the relevant description in the embodiment shown in fig. 3 and is not described again.

The stored communication state information of the network area may be obtained in a manner of periodically reporting by multiple service servers, or may be obtained by the priority management device in a manner of actively querying, which may be referred to in the related description of step 701, and is not described again.

806. And the priority management equipment sends a second priority response message to the first service server.

Wherein the second priority response message may be used to indicate authorization success or authorization failure. For example, when the priority of the object is determined to be the desired priority in step 805, the second priority response message may be used to indicate that authorization was successful; the second priority response message may be used to indicate an authorization failure when the priority of the object is determined not to be the desired priority in step 805.

Further, the second priority response message may further include identification information of the object, and at this time, the second priority response message may be used to indicate a desired priority for authorizing the object identified by the identification information of the object to use the object.

807. The first service server sends a first priority response message to the client.

808. And the priority management equipment sends a priority occupation message to the second service server.

The priority occupation message may include identification information of the object and an expected priority of the object, and the priority occupation message may be used to notify the second service server that the expected priority is occupied by the object.

Further, the priority occupation message may further include network area information, and at this time, the priority occupation message may be used to notify the second service server that the desired priority is occupied by the object in the network area corresponding to the network area information.

809. The first service server places a call to the object using the desired priority.

In one example, when the object is a call, the traffic server requests unicast transmission resources for the call to a mobile communication network device (e.g., PCRF) for users participating in the call. Specifically, under the unicast condition, the service server sends the priority to the mobile communication network device, and the mobile communication network device allocates unicast transmission resources for the call of the user according to the priority; when the network is congested, the mobile communication network device maintains or releases unicast transmission resources for the call of the user according to the priority. In the broadcast case, when the service server requests broadcast transmission resources from a mobile communication network device (such as BM-SC) for the call, the mobile communication network device allocates the broadcast transmission resources for the call according to the priority; when the network is congested, the mobile communication network device holds or releases the broadcast transmission resource for the call according to the priority.

In another example, when the object is a subscriber, the traffic server requests unicast transmission resources for the subscriber to a mobile communication network device (e.g., PCRF) for calls in which the subscriber participates. Specifically, under the unicast condition, the service server sends the priority to the mobile communication network device, and the mobile communication network device allocates unicast transmission resources for the call in which the user participates according to the priority; when the network is congested, the mobile communication network equipment maintains or releases unicast transmission resources for the call in which the user of the user participates according to the priority.

810. The first traffic server sends a desired priority notification message to the client.

The client may be a client used by the user or a user related to the user, and may be the same as or different from the client in step 801; the desired priority notification message may be used to notify the object that the priority is the desired priority.

Wherein, the execution sequence of steps 807 and 809 can be adjusted without limitation.

Optionally, when only one object is allowed to use at the same time with one priority, if there is already another object using the requested priority value, the priority management device determines to send a priority recycling request to the service server corresponding to the another object. At the same time, the priority recycling request can be sent to the relevant server with an unoccupied priority value.
