Description

Registration method and device of terminal equipment
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for registering a terminal device.
Background
In the 5 th generation (5G) communication system, after the terminal equipment is accessed, the terminal equipment can be in a power saving mode as much as possible under the condition of not influencing normal service. For example, after the terminal device completes the registration process of accessing the 5G network, if the timer starting condition is met, the terminal device triggers to start the T3540 timer, and when the T3540 timer times out, the terminal device enters an idle state and is in a power saving mode.
When the terminal equipment redirects or reselects from the 4G network to the 5G network, because the terminal capability is different in some different systems, the capability needs to be updated through a protocol data unit (Protocol Data Unit, PDU) session resource modification (modification) process after the terminal equipment is accessed to the 5G network, so that the terminal equipment needs to initiate a PDU session resource modification process again after the 5G network is accessed. But the terminal device starts a T3540 timer after completing registration of the 5G network. After the terminal device starts the timer, the PDU session resource modification procedure is not initiated. When the T3540 timer expires, the terminal device automatically releases the N1 interface signaling and enters an idle state. And then the terminal equipment initiates a service request based on signaling again to return to a connection state, further initiates a PDU session resource modification process, after the process is finished, the terminal can not restart the timer, and if the network side does not initiate a release process, the terminal equipment can always keep the connection state, and the power consumption of the terminal equipment is increased.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application scenario described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application, and as a person of ordinary skill in the art can know that the technical solution provided by the embodiment of the present application is applicable to similar technical problems as the new application scenario appears. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
Fig. 1 illustrates a communication system architecture, and it should be understood that the embodiment of the present application is not limited to the system shown in fig. 1, and the apparatus in fig. 1 may be hardware, software that is functionally divided, or a combination of the two. As shown in fig. 1, the system architecture provided in the embodiment of the present application includes a terminal device and a network device. The embodiment of the application does not limit the number of terminal devices and network devices included in the system. A core network device may also be included in the communication system.
A Terminal device (UE), also called a Terminal device, a Terminal, a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, such as a handheld device, an in-vehicle device, etc., with a wireless connection function. Currently, some examples of terminals are: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (Mobile Internet Device, MID), a wearable device, a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, a wireless terminal in industrial control (Industrial Control), a wireless terminal in unmanned (self driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.
The network device related in the embodiment of the present application may also be called a base station, AN Access network device or AN Access Node (AN for short), and provides a wireless Access service for a terminal device. The network device may specifically be an evolved base station (english: evolutional Node B, abbreviated as eNB or eNodeB) in a long term evolution (Long Term Evolution, LTE) system, or a base station device (gNB) in a 5G network, which the present application is not limited to.
Illustratively, the core network device may include an access and mobility management entity (Access and Mobility Management Function, AMF), a session management function entity (session management function, SMF), or the like.
In the 5G network, it is considered that after the terminal device accesses the network, the power consumption of the terminal device needs to be reduced as much as possible under the condition of not affecting the normal service. At present, after the terminal equipment in the idle state is accessed to the 5G network, a timer can be started, and when the timer is overtime, the terminal equipment enters the idle state, so that the electric energy consumption can be reduced. Alternatively, the timer may be a T3540 timer.
Referring to fig. 2, a schematic diagram of a possible registration procedure of a terminal device is shown.
S201, the terminal equipment in an idle state initiates a registration flow.
S202, the terminal equipment determines that the starting condition of the T3540 timer is met after finishing the registration process.
The timer start condition may include one or more of the following:
(1) The next request (FOR) flag bit=0 in the registration request sent by the terminal device.
(2) The terminal device receives the registration acceptance message, which indicates that the terminal device completes the registration process.
(3) No protocol data unit (Protocol Data Unit, PDU) session resources are activated/no PDU session establishment is performed.
(4) No air-interface data radio bearer (Data Radio Bearer, DRB) situation is established.
It should be appreciated that when FOR flag=1 in the registration request, or PDU session resources need to be activated/established after the registration procedure is completed, or air interface DRBs need to be established, the T3540 timer is not started.
In the initial registration scenario, if the initial registration of the terminal device is FOR emergency services, or the established NAS signaling connection needs to be prolonged after the initial registration procedure is completed (e.g. due to uplink signaling to be sent), the terminal device sets for=1.
In the mobility and period registration scenario, the terminal device sets for=1 when the terminal device satisfies any one of a), b), or c) below.
a) Mobility and periodic registration update procedures are initiated upon request by the upper layers to establish an emergency PDU session.
b) After receiving the request of the upper layer for sending the NAS signaling of the emergency service fallback, the mobility and periodical registration updating process is started.
c) There is a need to extend the established NAS signaling connection after completion of the registration procedure for mobility and periodic registration updates (e.g., due to uplink signaling to be sent, but no user data to be sent).
After the terminal device starts the timer, the terminal device stops the timer when the terminal device satisfies any one of the following conditions.
(1) There is data to send;
(2) An emergency call flow is provided;
(3) Network initiated de-registration procedure.
It should be noted that, of course, other scenarios of starting the T3540 timer or stopping the timer are also defined in the protocol, which is not listed in the embodiment of the present application.
S203, starting a T3540 timer.
S204, determining whether signaling to be transmitted exists, if yes, executing S205, and if not, executing S210.
S205, whether the emergency call signaling is performed, if not, S206 is performed, and if yes, S211 is performed.
S206, the signaling is not processed, and the T3540 timer is continuously maintained. S207 is performed.
S207, the timer T3540 is overtime, the terminal device releases the N1 interface signaling and enters an idle state. S208 is performed.
S208, the terminal equipment triggers the service flow entering the connection state.
In the scenario that the terminal device redirects from the 4G network to the 5G network or reselects the 5G network, since the terminal device capabilities are somewhat different under different systems, after the terminal device accesses the 5G network, these capabilities also need to be updated through PDU session resource modification procedures. Thus, the terminal device has signalling in the PDU session resource modification procedure that needs to be sent in step S204, but these signalling are not emergency call signalling. Thus, after the terminal device performs S208, S209 is performed.
S209, the terminal equipment executes PDU session resource modification flow.
S210, the timer T3540 times out, and the terminal device releases the N1 interface signaling, and enters an idle state.
S211, stopping the timer and triggering the emergency call signaling flow. After the emergency call signaling flow is triggered, the terminal device enters a connected state.
From the above, it can be seen that when the terminal starts the T3540 timer, if there is a normal signaling of the non-emergency call to be sent, the T3540 timer will not be stopped, after the timer is timed out, the terminal will enter the idle state and process, at this time, the terminal initiates a service flow entering the connected state, then executes the normal signaling of the non-emergency call, and after the normal signaling of the non-emergency call is completed, the terminal device will be in the connected state all the time, so as to increase the power consumption of the terminal device.
Based on this, an embodiment of the present application provides a registration method of a terminal device, which is shown in fig. 3. The method is applied to a terminal device, such as the method is performed by the terminal device or by a chip or chip system in the terminal device.
S301, the terminal equipment in an idle state initiates a registration process.
The scenario that the terminal device in idle state initiates the registration procedure may include:
in one scenario, a terminal device in an idle state initiates a registration procedure when redirected by a first type of network to a second type of network.
In another scenario, when the terminal device in the idle state reselects the second type network, a registration procedure is initiated.
Optionally, the first type network is a 4G network or a 3G network, and the second type network is a 5G network or other upgraded network, such as a 6G network, etc.
S302, when the terminal equipment completes the registration flow and determines that the starting condition of a timer is met and the signaling needing to be sent exists on the terminal equipment, the timer is started in a suspending mode.
The degree of urgency of the signaling to be transmitted is not limited, and whether or not the signaling is urgent is not limited.
The starting condition of the timer is as described above, and will not be described here again.
Alternatively, it may be determined by an application layer of the terminal device whether there is signaling to be transmitted.
For example, in the scenario that the terminal device redirects to the 5G network by the 4G network or in the scenario that the terminal device reselects to the 5G network, the signaling that the terminal device needs to send includes, but is not limited to, signaling generated by the protocol data unit PDU session resource modification procedure. The signaling generated by the protocol data unit PDU session resource modification procedure can send PDU session resource modification request information to the core network equipment, receive PDU session resource modification command information sent by the core network equipment, and then send PDU session resource modification completion information to complete the PDU session resource modification procedure.
S303, starting the timer after finishing the flow of sending the signaling.
The timer is used for indicating the terminal equipment to enter an idle state when the timer is overtime.
In one possible implementation manner, after the terminal device completes the registration procedure, the timer is started when it is determined that a starting condition of the timer is met and no signaling to be sent exists on the terminal device.
After the terminal equipment finishes registration, the timer is not started immediately under the condition that the timer starting condition is met, and whether signaling needing to be sent exists on the terminal equipment is determined, and under the condition that the signaling is needed, the terminal equipment stops starting the timer, and after the signaling flow is finished, the timer is started again, and after the timer is overtime, the terminal equipment can enter an idle state. When the timer is overtime, the terminal equipment enters an idle state. And then the terminal equipment initiates a service request based on signaling to return to a connection state, further initiates a signaling process, and after the flow is finished, the terminal does not restart the timer. The above scheme does not need to initiate a service request based on signaling to enter a connection state from an idle state, so that signaling consumption is reduced, and the terminal equipment can complete a signaling sending process, such as a PDU session resource modification process. The terminal device can enter an idle state after the timer is started and overtime, so that the electric energy consumption is reduced.
The following describes a scenario of redirecting a 4G network to a 5G network in detail, which is shown in fig. 4.
The flow starts: the terminal device is in an idle state, detects a signal of a base station in the 5G network, and resides on a cell of the base station.
S401, the terminal equipment initiates a registration flow for registering to the 5G network and completes.
S402, determining whether the starting condition of the timer is met, if yes, executing S403, otherwise, executing S409.
FOR example, FOR the 5G registration procedure, the terminal device initiates the registration procedure in the idle state, the FOR flag bit carried in the registration request is 0, after the registration procedure is completed, the terminal device does not activate/establish the PDU session, and does not establish the air interface DRB information, and then the T3540 timer needs to be started, i.e. the starting condition of the timer is satisfied, and in other situations, the T3540 timer does not need to be started, i.e. the starting condition of the timer is not satisfied.
S403, if there is signaling to be sent in the terminal equipment, executing S404 if yes, and executing S405 if no.
Optionally, the terminal device may determine whether there is a signaling to be sent through an application layer, and for a procedure of redirecting from the 4G network to the 5G network or reselecting the 5G network, the application layer of the terminal device may have a PDU session resource Modify message to be sent.
S404, triggering the signaling sending flow, and executing S405.
Taking the flow of redirecting from the 4G network to the 5G network or reselecting the 5G network as an example, the terminal equipment sends a PDU session resource modification request message to the core network equipment, the PDU session resource modification request message can be sent to the core network equipment through an uplink direct transmission message, the PDU session resource modification command message sent by the core network equipment is received through a downlink direct transmission message, and then the PDU session resource modification completion message is further sent to the core network equipment through the uplink direct transmission message, so that the PDU session resource modification flow is completed.
S405, starting a timer.
Optionally, the method may further include:
s406, judging whether the emergency call signaling and/or data to be sent exist or not, if yes, executing S407, otherwise, executing S408.
And judging whether the emergency call signaling and/or data to be transmitted exist or not, and if yes, namely, the terminal equipment exists the emergency call signaling to be transmitted or the data to be transmitted or the emergency call signaling and the data to be transmitted.
Judging whether the emergency call signaling and/or data to be transmitted exist or not, and if not, namely, the terminal equipment does not exist the emergency call signaling to be transmitted or the data to be transmitted.
S407, stopping the timer, initiating a connection state signaling call or a data service request process by the terminal equipment, and entering a connection state by the terminal equipment. The flow ends.
S408, after the timer is overtime, the terminal equipment enters an idle state from a connection state. The flow ends.
S409, the terminal equipment does not start a timer and keeps a connection state. Such as the transmission of connection-state data or the transmission of voice traffic, etc. The flow ends.
In the embodiment of the application, after the registration process is finished through the terminal equipment, whether the application layer signaling to be transmitted exists or not is firstly judged, if so, the timer is started after the application layer signaling is transmitted, so that the condition that the application layer signaling is transmitted after the timer is overtime, and the terminal equipment keeps a connection state all the time under the condition that no service data is transmitted is avoided, and the power saving of the terminal is facilitated.
