Detailed Description
In an existing Long Term Evolution (LTE) trunking system, for a group call called ue, when the ue is newly powered on or roams into a coverage cell with a cluster, a late access procedure is performed, and the ue can start to enter a monitoring state after receiving a periodic sounding paging message and a periodic GroupCallConfig message after the ue needs to wait for successful cluster registration. When the user equipment performs cell switching and TAU updating occurs, the user equipment can start to enter a monitoring state after receiving a periodic paging message and a periodic grouCallConfig message after waiting for successful cluster TAU updating, and the periodic paging message generally has longer configuration time, so that the user delayed access experience is not good.
Based on this, the embodiments of the present invention provide a method, an apparatus, and a system for delayed access of a cluster group call, which can reduce transmission of air interface signaling, reduce waste of communication resources, reduce delay of delayed access of a UE, and improve user experience.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The data communication method provided by the embodiment of the invention can be applied to an LTE system. The method for the cluster group call late access is described below with reference to fig. 1 to 5.
Referring to fig. 1, a flowchart of a method for a group call late access provided in an embodiment of the present invention is applied to a core network node device, where the method may include:
s101, the core network node equipment determines whether the user equipment sending the data request is the user equipment accessed by the group call delay.
In some embodiments, the determining, by the core network node device, whether the user equipment sending the data request is a user equipment with a delayed group call access includes: when the data Request is a cluster registration Request (called as trunk registration Request) and it is determined that a group call service exists in a packet corresponding to the user equipment, the core network node equipment determines that the user equipment is the user equipment which is accessed after a group call delay. For example, when the UE is newly powered on or roams into a cell with cluster coverage, after the UE standard LTE registration is successful, the UE confirms that the cell supports the cluster function, and sends a cluster registration Request, which is a Trunking registration Request. When the core network node equipment receives the trunk Register Request sent by the base station, whether a group call service exists in a packet corresponding to the UE or not is confirmed. And if so, determining the UE as the UE accessed by the group call in a delayed manner. For another example, when the UE needs to perform cell handover, after the cell reselection is successful, a TAU request is sent in a newly handed over cell. And the base station sends the TAU request to core network node equipment. When the core network node equipment receives the TAU request sent by the base station, whether a group calling service exists in a group corresponding to the UE is confirmed. And if so, determining the UE as the UE accessed by the group call in a delayed manner.
And S102, when the user equipment is determined to be the user equipment accessed in the group call delay, the core network node equipment sends an indication message to the base station when responding to the data request, wherein the indication message is used for indicating the base station to send cluster group resource configuration information and group call service channel configuration information to the user equipment.
Wherein, the cluster resource configuration information and the group call service channel configuration information are carried in the downlink direct transfer message containing the response message aiming at the data request.
In specific implementation, when the core network node device determines that the UE is a UE that is late in group call access, an indication message is sent to the base station in response to the data request, where the indication message is used to indicate the base station to send cluster group resource configuration information and group call service channel configuration information to the UE. For example, when the data request is a Trunking registration request (Trunking Register request), the core network node device sends the indication message to the base station when sending a Trunking registration Accept (Trunking Register Accept) message to the base station. For another example, when the data request is a TAU request, the core network node device sends the indication message to the base station when sending a TAU Accept message (Tracking Area Update Accept) message to the base station.
In some embodiments, the indication message is carried in a downlink non-access stratum NAS transport message sent by the core network node device to the base station, and the downlink NAS transport message is further used to carry a response message to the data request, such as a cluster registration accept message or a TAU accept message. For example, the core network node device adds a field to the downlink NAS transport message, where the field is used to carry the indication message.
In some embodiments, the core network node device may further send the indication message while sending a downlink NAS transport message carrying a response message for the data request. At this time, an indication message needs to be newly constructed, the present invention does not limit the type and content of the indication message, as long as the base station can be instructed to send the cluster group resource configuration information and the group call traffic channel configuration information to the UE.
The above describes a processing method of a core network node device, and the following describes a method for late access of a cluster group call provided by the embodiment of the present invention from a base station side.
Referring to fig. 2, a flowchart of a method for group call late access provided in an embodiment of the present invention is applied to a base station, where the method may include:
s201, a base station receives a data request sent by user equipment and sends the data request to core network node equipment.
The data Request received by the base station from the ue may specifically be a sounding Register Request or a TAU Request. And the base station bears the traversing Register Request or the TAU Request in the uplink NAS transmission message and sends the traversing Register Request or the TAU Request to the core network node equipment.
S202, a base station receives an indication message sent by the core network node equipment, wherein the indication message is used for indicating the base station to send cluster group resource configuration information and group call service channel configuration information to the user equipment.
After receiving the indication message sent by the core network node device, the base station determines whether the cell or the tracking area TA corresponding to the user device establishes the group call resource. And if the group calling resource is not established in the cell or the tracking area TA corresponding to the user equipment, establishing the group calling resource in the cell or the TA. The group call resources include cluster group control channel resources and cluster service channel resources. After the group call resource is established, cluster group resource configuration information and the group call service channel configuration information are sent to the user equipment. If the base station determines that the cell or the tracking area TA corresponding to the user equipment establishes the group call resource, the base station directly sends the cluster group resource configuration information and the group call service channel configuration information. Compared with the prior art that the sounding paging message is sent periodically, and the UE needs to wait for the call period to receive the corresponding message, the method provided by the embodiment of the invention obviously reduces the user waiting time, improves the user access efficiency, and reduces the transmission of air interface signaling.
S203, the base station sends a downlink direct transfer message to the ue, where the downlink direct transfer message is used to carry a response message for the data request, the cluster group resource configuration information, and the group call service channel configuration information.
When the data request is a cluster registration request, the response message for the data request is a cluster registration acceptance message; when the data request is a TAU request, the response message for the data request is a TAU acceptance message.
The cluster resource configuration information is used for the user equipment to establish a cluster control channel, and the group call service channel configuration information is used for the user equipment to establish a cluster service channel.
The cluster Group resource configuration information may include a cluster Group identifier (english name is TrunkingGroup ID, chinese name is cluster Group ID identifier), a G-RNTI (english name is Group Radio Network temporary identity, chinese name is Group Radio Network temporary identifier), a Call Priority (Call Priority), and the like. Wherein, the trunk Group ID is used for identifying the ID number of the current call Group; the G-RNTI is used for identifying a group identifier, and the UE demodulates the PDCCH of the group to be monitored currently according to the G-RNTI; the call priority is used for call selection control.
The group call service channel configuration information mainly includes Radio Resource configuration Dedicated (i.e., TTCH channel Resource configuration information, the chinese name of TTCH is Trunking service channel, and english is called Trunking traffic channel). The Radio Resource configuration specified comprises cluster data RB (Radio Bear in English and Radio bearer in Chinese) bearing information and cluster physical downlink shared channel PDSCH configuration information, wherein the cluster data RB bearing information is used for informing the terminal of the concrete information of the cluster data bearing RB; cluster group PDSCH configuration information for PDSCH channel usage.
The processing method of the base station side is introduced above, and the method for the cluster group call late access provided by the embodiment of the invention is introduced from the UE side.
Referring to fig. 3, a flowchart of a method for a group call late access provided in an embodiment of the present invention is applied to a UE, where the method may include:
s301, the UE sends a data request to the base station.
In a specific implementation, the data Request may be a traversing Register Request or a TAU Request. For example, when the UE is newly powered on or roams into a cell with cluster coverage, after the UE standard LTE registration is successful, the UE confirms that the cell supports the cluster function, and sends a sounding Register Request. For another example, when the UE needs to perform cell handover, after the cell reselection is successful, a TAU request is sent in a newly handed over cell.
S302, the UE receives a downlink direct transmission message sent by the base station, wherein the downlink direct transmission message is used for bearing a response message aiming at the data request, cluster group resource configuration information and group call service channel configuration information.
Wherein the response message to the data request is a cluster registration accept message or a TAU accept message.
S303, the UE analyzes the downlink direct transmission message, acquires the cluster group resource configuration information and the group calling service channel configuration information, and establishes a cluster control channel and a cluster service channel by using the cluster group resource configuration information and the group calling service channel configuration information.
The UE needs to analyze the downlink direct transmission message, acquires cluster group resource configuration information and the group calling service channel configuration information from the downlink direct transmission message, and establishes a cluster control channel and a cluster service channel by using the cluster group resource configuration information and the group calling service channel configuration information so as to quickly enter a group calling monitoring state.
