The present disclosure relates to a mobile communication technology, and more particularly to a method for processing a trunking communication service, core network device, User Equipment (UE) and a storage medium.
A trunking communication service refers to a dedicated trunking communication service such as commanding and dispatching provided for multiple group users of a department, a unit and the like by virtue of a trunking communication shared network formed by trunking communication systems with technical characteristics of channel sharing, dynamic allocation and the like. Along with continuous development of the communication network, a trunking communication system will provide increasingly rich trunking communication services. At present, there are two common trunking communication services: one is a call service, such as a Push To Talk (PTT) group call service; and the other is a non-call service, such as short message, picture, positioning, remote stopping, remote starting and PTT information updating services.
In a trunking communication service, the user equipment which actively initiates a trunking communication service request has a speaking right, and is regarded as a speaking the user equipment, and other the user equipments which receive the trunking communication service request are regarded as non-speaking the user equipments. Specifically, the speaking the user equipment sends a trunking communication service request message to trunking core network device through an uplink control channel, the trunking core network device analyzes the trunking communication service request message, and determines a service type and a group identifier according to a content (such as a call type and a call attribute, etc) carried in the trunking communication service request message. And the trunking core network device generates a paging message according to the group identifier, and sends it to a base station, the base station sends the paging message to the non-speaking the user equipment through a paging channel. The non-speaking the user equipment analyzes the paging message after receiving the paging message, matches the group identifier, and returns a paging response in case of successful matching. The base station allocates a downlink shared channel resource for a group call, establishes a downlink shared channel to transmit downlink data, and sends shared channel resource information to a group user through a control channel. The non-speaking user starts receiving the data on the downlink shared channel for trunking communication service after receiving a control channel message.
On one hand, in a group call service during trunking communication, for a the user equipment which has established a connection with trunking core network device, such as group call speaking the user equipment, when other the user equipment initiates another trunking communication service to the user equipment, the trunking core network device analyzes a trunking communication service request message sent by the other the user equipment to determine a type of the trunking communication service. And if the trunking communication service is a call service, the user equipment is controlled to quit a current call service and access the new call service, or the user equipment is controlled to keep the current call service and reject the new call service. And if it is a non-call service, the user equipment is controlled to keep the current call service and receive the non-call service. However, for a the user equipment which does not establish a connection with the trunking core network device, such as group call non-speaking the user equipment, the user equipment does not directly establish the connection with the trunking core network device, which makes it impossible for the trunking core network device to determine whether the user equipment is currently answering a group call or not, so that the trunking core network device may not control the user equipment to access or reject the new trunking communication service.
On the other hand, no matter whether a trunking communication service request message sent to trunking core network device by speaking the user equipment is a call service or a non-call service, the trunking core network device sends a paging message carrying a group identifier to a base station for sending to non-speaking the user equipment through the base station after receiving the trunking communication service request message, and the non-speaking the user equipment does not know whether a call service or a non-call service is received after receiving the paging message.

the computer-executable instruction is used for executing the abovementioned method for processing the trunking communication service provided by the embodiment on the third aspect.
According to the method for processing the trunking communication service, core network device, user equipment and storage medium provided by the embodiments of the present disclosure, the user equipment receives a trunking communication service request which is sent by the trunking core network device and carries the service type identifier, and then the user equipment may determine whether to receive the trunking communication service according to the service type identifier. In such a manner, non-speaking user equipment which does not establish a connection with the trunking core network device in the group call service may determine whether to receive a new trunking communication service by itself according to the service type identifier, so that the problem in the existing technology that the trunking core network device may not control the user equipment to access or reject the new trunking communication service due to the fact that the user equipment does not establish the connection with the trunking core network device is solved.
In addition, according to embodiment 1 of the present disclosure, the service type identifier is added into the trunking communication service request received by the user equipment, and then the non-speaking user equipment may know a type of the trunking communication service received by itself, and may independently determine whether to receive the trunking communication service according to a practical condition, so that the problem in the existing technology that the non-speaking user equipment does not know whether a call service or a non-call service is received after receiving the paging message is solved.
In step 101: a user equipment receives a trunking communication service request message sent by trunking core network device, the trunking communication service request message including a service type identifier.
Herein, the user equipment is a terminal equipment in a current group call service in progress.
It is important to note that the user equipment mentioned here may be various kinds of terminal equipments supporting the trunking communication service. And for example, the terminal equipment may be a handheld intelligent terminal equipment, including a laptop, a mobile phone like Iphone, a tablet computer like Ipad and the like, and may also be fixed terminal equipment, including a computer and the like.
Specifically, the user equipment mentioned here is terminal equipment in the current group call service in progress, may be non-speaking user equipment, and may also be speaking user equipment.
When the current group call service is established, a speaking user equipment establishes a connection with the trunking core network device; the speaking UE sends a current group call service request message to the trunking core network device. And the trunking core network device sends a paging message to a base station after receiving the current group call service request message. Then the base station sends the paging message to non-speaking user equipment through a paging channel, and establishes a downlink shared channel resource to enable the non-speaking user equipment to receive the paging message and receive group call downlink data on a downlink shared channel to perform the current group call service.
When another user equipment initiates another trunking communication service request message to the user equipment in the current group call service in progress, the trunking core network device analyzes the trunking communication service request message to obtain a service identifier corresponding to a trunking communication service after receiving the trunking communication service request message, adds a service type identifier into a paging message to obtain a trunking communication service request message including the service type identifier according to a service type corresponding to the service identifier, or generates the trunking communication service request message including the service type identifier according to the service type corresponding to the service identifier, and sends the trunking communication service request message including the service type identifier to the base station. Then the base station sends the trunking communication service request message to the user equipment in the current group call service in progress through a second downlink shared channel established by initiating another trunking communication service request by another UE. Here, another UE may be any user equipment except the user equipment in the current group call service in progress.
It is important to note that the service type identifier in the embodiment of the present disclosure may be a field added in an existing paging message to distinguish the type of the trunking communication service. For example: if the trunking communication service is a call service, a specific identifier, such as 0, is added to the field to represent that the trunking communication service is a call service; and if the trunking communication service is a non-call service, another specific identifier, such as 1, is added to the field to represent that the trunking communication service is a non-call service.
For an identifier of the field, abovementioned 0 and 1 are only adopted as examples for description. During a practical application, another symbol, such as an English letter, etc, may also be adopted, which is not specifically limited herein. In addition, a position of the field in a data packet may be set according to a practical condition, and for example: the field may be in a header of the data packet, may also be in an end of the data packet, and the like, which is also not specifically limited herein.
In step 102: the user equipment determines whether to receive the trunking communication service according to the service type identifier.
Specifically, the trunking communication service includes a call service and a non-call service, and the call service further includes a group call or a single call. For a trunking communication technology, a user equipment in a current group call service in progress is not allowed to perform another call service at the same time. For example, the user equipment may not answer two paths of video group calls at the same time. Then, if there is another call request for the user equipment, it is necessary to make a decision about whether to receive the call request or reject the call request. Therefore, it is necessary to determine a specific type of the trunking communication service request initiated to the user equipment by another user equipment, and in the embodiment of the present disclosure, the service type identifier is carried in the trunking communication service request to solve that problem.
When the service type identifier included in the trunking communication service request message is a service identifier corresponding to a non-call service, since a non-call service and a call service may be performed at the same time, the user equipment may keep the current group call service in progress and receive the non-call service.
When the service type identifier included in the trunking communication service request message is a service identifier corresponding to a group call service, since two call services may not be performed at the same time during trunking communication, the user equipment may select to keep the current group call service in progress and reject the new call service, may also terminate the current group call service in progress and access the new call service, and may further display a prompting message used for prompting a user and enable the user to select whether to keep the current group call service in progress and reject the new call service or terminate the current group call service in progress and access the new call service.
In step 201: a user equipment receives a trunking communication service request message sent by a trunking core network device, the trunking communication service request message including a service type identifier.
Herein, the user equipment is a terminal equipment in a group call service in progress.
In step 202: if the service type identifier is a service identifier corresponding to a non-call service, the user equipment keeps a group call service and receives the non-call service, and the processing flow is ended.
In step 203: if the service type identifier is a service identifier corresponding to a call service, the trunking communication service request message also includes a priority corresponding to the call service.
It is important to note that a priority sequence of a group call service and a single call service is preset by the trunking core network device. For example, every time when a call service is established, the trunking core network device may set a priority for it according to an attribute, such as an emergency degree, of the call service.
Herein, the group call service and the call service are only adopted to distinguish different group call services, the group call service represents the current group call service in progress, and the call service represents a new group call service.
In step 204: the user equipment compares a priority corresponding to the group call service with the priority corresponding to the call service.
In step 205: if it is determined that the priority of the group call service is higher than the priority of the call service, the user equipment keeps the group call service and rejects the call service, and the processing flow is ended.
In step 206: if it is determined that the priority of the group call service is lower than the priority of the call service, the user equipment terminates the group call service and accesses the call service.
According to embodiment 1 of the present disclosure, the user equipment receives a trunking communication service request sent by the trunking core network device, the trunking communication service request includes the service type identifier. Then the user equipment may determine whether to receive the trunking communication service according to the service type identifier. In such a manner, non-speaking UE which does not establish a connection with the trunking core network device in the group call service may determine whether to receive a new trunking communication service by itself according to the service type identifier. Moreover, the solution of embodiment 1 of the present disclosure may also be used for speaking user equipment.
In addition, according to embodiment 1 of the present disclosure, the service type identifier is added into the trunking communication service request received by the user equipment, and then the non-speaking user equipment may know a type of the trunking communication service received by itself, and may independently determine whether to receive the trunking communication service or not according to a practical condition.
In order to implement the abovementioned method for processing the trunking communication service provided by embodiment 1 of the present disclosure, embodiment 1 of the present disclosure also provides a user equipment. The technical principle and achieved technical effects are similar to those of the abovementioned method for processing the trunking communication service provided by embodiment 1 of the present disclosure, and will not be elaborated herein. A structure of the user equipment provided by embodiment 1 of the present disclosure will be described below in detail.

Or, the comparison module 13 is arranged to, before the determination module 12 terminates the current group call service in progress and accesses the new call service, compare the priority corresponding to the current group call service in progress with the priority corresponding to the new call service, and determine that the priority of the current group call service in progress is lower than the priority of the new call service.
Furthermore, the call service includes a group call service and a single call service.
In step 301: a trunking core network device receives a trunking communication service request message including a service type identifier which is sent by another user equipment.
It is important to note that anther user equipment mentioned here is a user equipment which initiates another group call service to a user equipment in a group call service in progress. Another user equipment may be any user equipment except the user equipment which participates in the group call service in progress.
In step 302: the trunking core network device forwards the received trunking communication service request message including the service type identifier to a user equipment, or analyzes the trunking communication service request message to obtain a service identifier, adds the service identifier into a corresponding paging message to generate a paging message including the service type identifier, and sends the generated paging message including the service type identifier to the user equipment.
Specifically, the trunking core network device adds the service type identifier into the paging message. When a service type is a non-call service type, the trunking core network device adds a service identifier corresponding to a non-call service into the paging message; and when the service type is a service type corresponding to a call service, the trunking core network device adds a service identifier corresponding to the call service into the paging message.
In step 303: the trunking core network device sends the trunking communication service request message including the service type identifier to the user equipment, herein the service type identifier is used to enable the user equipment to determine whether to receive the trunking communication service.
Herein, the user equipment is a terminal equipment in a current group call service in progress.
Specifically, when the service type identifier is a service identifier corresponding to a non-call service, the user equipment keeps the current group call service in progress and receives the non-call service; and when the service type identifier is a service identifier corresponding to a call service, the user equipment may select to keep the current group call service in progress and reject the new call service, may also terminate the current group call service in progress and access the new call service, and may further display a prompting message used for prompting a user and enable the user to select whether to keep the current group call service in progress and reject the new call service or terminate the current group call service in progress and access the new call service.
According to embodiment 2 of the present disclosure, the trunking core network device receives another trunking communication service request sent by another user equipment, adds the service type identifier into another trunking communication service request to obtain a trunking communication service request carrying the service type identifier, and sends the trunking communication service request carrying the service type identifier to the user equipment, and then the user equipment may determine whether to receive the trunking communication service according to the service type identifier. In such a manner, the non-speaking user equipment which does not establish a connection with the trunking core network device in the group call service may determine whether to receive a new trunking communication service or not by itself according to the service type identifier.
