As described above, the UE states defined in 4G are two states, RRC Connected and RRC IDLE (i.e., E-UTRA RRC _ Connected and E-UTRA RRC _ IDLE). 5G is expected to provide more stringent UE state transition requirements than 4G.

In the face of the 5G requirement, an embodiment of the present invention provides a state control method for a terminal device, where the method adapts to different 5G service requirements by defining a sub-state of an E-UTRA RRC _ Connected.

Specifically, the embodiment of the present invention defines a new state for the terminal device according to the requirement of the 5G on the air interface. Based on the definition of LTE, the state of the terminal device in RRC is: E-UTRA RRC _ Connected and E-UTRA RRC _ IDLE, on which the embodiment of the present invention defines a new state of the terminal device of 5G, as shown in fig. 2.

The embodiment of the invention adopts the states of a main State (UE State) and a Sub State (Sub UE State) to control the State conversion of the terminal equipment. Specifically, the main states of the terminal device are two basic states, namely an RRC connected state and an RRC idle state. The sub-states of the terminal device are further refined and enhanced based on the RRC connected state, that is, the sub-states are states in the RRC connected state, and specifically, several sub-states, sustate 1, …, and sustate, may be defined in the embodiment of the present invention, as shown in fig. 2. The new sub-state can be controlled by a Media Access Control (MAC) Layer and a Physical Layer (Physical Layer), and at this time, the new sub-state can be called as an MAC state (E-UTRA MAC _ States); the new sub-state may still be controlled by the RRC layer, and in this case, may be referred to as an RRC sub-state (E-UTRA RRC _ Connected _ states).

When the newly added sub-state is controlled by the MAC layer, the sub-state is a state in the RRC connected state, and firstly enters the RRC connected state in the RRC layer, so that the sub-state is a state in the air interface of the terminal device controlled by the MAC layer under the overall control of the RRC layer.

Specifically, if the sub-state is controlled by the MAC layer and the physical layer (the sub-state is referred to as E-UTRAMAC _ States), the MAC layer may use a MAC Control Element (CE), a MAC Protocol Data Unit (PDU), or a physical layer control channel or a physical layer traffic channel to perform control of related state transition. For example, the physical layer control channel may include a Physical Downlink Control Channel (PDCCH) and/or a Physical Uplink Control Channel (PUCCH), and the physical layer traffic channel may include a Physical Downlink Shared Channel (PDSCH) and/or a Physical Uplink Shared Channel (PUSCH).

If the sub-state is controlled by the RRC layer (this sub-state is referred to as RRC _ Connected _ states), the RRC layer may perform state transition control using RRC signaling, or may perform state transition control using the control method used by the MAC layer.

In the embodiment of the present invention, when the terminal device is in the RRC connected state, the terminal device can be in one sub-state at the same time.

In the embodiment of the present invention, state transition may be performed between the sub-states, and each sub-state may directly transition to the RRC idle state, or may transition to the RRC idle state after transitioning to the main state of the RRC connected state. Specifically, if the sub-state is controlled by the MAC layer and the physical layer, it is usually required to transition to the main state of the RRC connected state and then to transition to the RRC idle state; if the sub-state is controlled by the RRC layer, a transition from the sub-state to the RRC idle state can be made directly.

Referring to fig. 3, a schematic diagram of a terminal state transition in an embodiment of the present invention is shown. In fig. 3, the sub-states are controlled by the MAC layer and the physical layer, and as shown in fig. 3, when a Release (Release) connection is required, that is, when the RRC connection state transitions from the main state of the RRC connection state to the main state of the RRC idle state, the sub-states need to transition to the main state of the RRC connection state first, and then transition from the main state of the RRC connection state to the main state of the RRC idle state. In fig. 3, the transition between sub-states is straightforward.

Referring to fig. 4, another schematic diagram of terminal state transition in the embodiment of the present invention is shown. In fig. 4, the sub-states are controlled by the RRC layer, and as shown in fig. 4, when a Release (Release) connection is required, that is, when the RRC connection state transitions from the main state of the RRC connected state to the main state of the RRC idle state, the sub-states may first transition to the main state of the RRC connected state and then transition from the main state of the RRC connected state to the main state of the RRC idle state in a manner similar to fig. 3; alternatively, the primary state can be transited from the sub-state to the RRC idle state directly.

In the embodiment of the present invention, when the terminal device transitions from the primary state of the RRC idle state to the primary state of the RRC connected state, the terminal device may Enter (Enter) a sub-state from the primary state of the RRC connected state at the same time. When the inter-substate transition (Transit) condition is not met or the Release (Release) does not occur, the terminal device is always in the main state of the RRC connected state and in a certain substate. When a transition (Transit) condition between sub-states is satisfied, the terminal device starts state transition between the sub-states.

In order to implement the state transition of the terminal device with low time delay and low power consumption, the embodiment of the invention defines the following sub-states:

1. strong linker status: in this state, the terminal device maintains uplink and downlink synchronization with the network.

2. Weak linker state: in the state, the terminal equipment sends a heartbeat message to the network at intervals of a first preset period; for example, the terminal device exchanges information with the network side once every 100 air interface Transmission Time Intervals (TTIs). In this state, the terminal device may complete an air interface link synchronization process by using a random access process to perform data transceiving.

3. Discontinuous linker status: in this state, the terminal device sends a heartbeat message to the network every second predetermined period, where the first predetermined period is less than the second predetermined period. For example, the terminal device performs information exchange with the network once at a period of the order of hours. In this state, the terminal device can use a non-orthogonal access mode to complete the sending and receiving of a short message.

An embodiment of the present invention provides a method for controlling a state of a terminal device, as shown in fig. 5, when the method is applied to a network side, the method includes:

step 51, determining whether the terminal device satisfies the state transition condition.

Here, the network side may configure the state transition condition in advance as necessary to trigger the state transition between the corresponding states. For example, the network side determines a target state of the terminal device according to a service type (for example, a period interval of service data transmission and reception) applied by the terminal device, and determines whether a current state of the terminal device is the target state, if so, the state transition condition is not satisfied, and if not, the state transition condition is satisfied.

Step 52, when the terminal device meets a state transition condition, controlling the terminal device to perform state transition, wherein the state transition includes: transitions between main states, transitions between sub-states, and transitions between main states and sub-states; the main state comprises an RRC connected state and an RRC idle state, the sub-states comprise a plurality of states in the RRC connected state, and the terminal equipment can be in only one sub-state at the same time.

Through the steps, the terminal equipment state is sunk to the air interface, so that the network side can make a quick response according to the behavior characteristics of the terminal equipment at the air interface, and the requirements of the 5G service can be met.

As an implementation manner, in the embodiment of the present invention, the sub-state may be controlled by the MAC protocol layer and the physical layer:

at this time, when the terminal device meets the state transition condition for transitioning from a certain sub-state (referred to as a first sub-state for convenience of description) to the RRC idle state, in step 52, the network side may control the terminal device to enter the RRC connected state from the first sub-state through signaling of a physical layer control channel or a message of a physical layer traffic channel, and release a resource corresponding to the first sub-state; and controlling the terminal equipment to enter an RRC idle state from an RRC connected state through RRC signaling, and releasing resources corresponding to the RRC connected state.

When the terminal device satisfies the state transition condition for transitioning from the RRC idle state to a certain sub-state (for convenience of description, referred to as a second sub-state), in step 52, the network side may control the terminal device to enter the RRC connected state from the RRC idle state through RRC signaling; and controlling the terminal equipment to enter the second sub-state from the RRC connection state through the signaling of the physical layer control channel or the information of the physical layer service channel.

As another implementation manner, in the embodiment of the present invention, the sub-state may be controlled by the RRC layer:

at this time, when the terminal device satisfies a state transition condition for transitioning from a certain sub-state (referred to as a third sub-state for convenience of description) to the RRC idle state, in step 52, the network side may control the terminal device to enter the RRC idle state from the third sub-state through RRC signaling, and release resources corresponding to the RRC connected state and the third sub-state.

When the terminal device satisfies a state transition condition for transitioning from the RRC idle state to a sub-state (for convenience of description, referred to as a fourth sub-state), in step 52, the network side may control the terminal device to enter the fourth sub-state from the RRC idle state through RRC signaling.

The above describes the state transition between the sub-state and the RRC idle state. In the embodiment of the invention, the terminal equipment can also perform state conversion between the sub-states. For example, when the terminal device satisfies the state transition condition for transitioning from the fifth sub-state to the sixth sub-state, in step 52, the network side may control the terminal device to transition from the fifth sub-state to the sixth sub-state through signaling of a physical layer control channel or a message of a physical layer traffic channel, or control the terminal device to transition from the fifth sub-state to the sixth sub-state through RRC signaling. The terminal device may also perform a state transition between an RRC idle state and an RRC connected state. For example, when the terminal device satisfies a state transition condition for transitioning from the RRC idle state to the RRC connected state, in step 52, the network side may control the terminal device to enter the RRC connected state from the RRC idle state through RRC signaling; and controlling the terminal equipment to enter a default sub-state from an RRC connection state through the RRC signaling or the signaling of a physical layer control channel or the message of a physical layer service channel.

Fig. 6 further shows an example of a transition between the above states, specifically:

1. the network side controls the terminal equipment to enter the RRC connection state, and when the terminal equipment enters the main state of the RRC connection state from the main state of the RRC idle state, the terminal equipment also enters the strong connection sub-state.

2. According to the service type applied by the terminal equipment (the assumption is that the data exchange period is above the hour level), the network side MAC layer directly sends a scheduling instruction to the terminal equipment and controls the terminal equipment to enter a discontinuous connection sub-state. After the scheduling instruction is confirmed by both sides, the network side and the terminal side respectively enter a discontinuous connection sub-state, and the terminal equipment sends a heartbeat message in a second preset period.

3. When the second predetermined period arrives (e.g., after the terminal device has gone through a deep sleep on the order of hours), the terminal device first listens to the network, including the broadcast and control channels. And resolves if it includes the control channel belonging to itself. When the terminal equipment is in the discontinuous connection sub-state, if the terminal equipment has uplink data to be sent, the short message is directly sent in a non-orthogonal mode.

Referring to fig. 7, a state control method according to an embodiment of the present invention is further described in the terminal device, as shown in fig. 7, the method includes:

step 71, the terminal device receives a state transition instruction sent by the network.

Here, the state transition instruction may be RRC signaling, signaling of a physical layer control channel, or a message of a physical layer traffic channel, etc. The terminal obtains the state transition instruction by receiving RRC signaling sent by the network and/or signaling of a physical layer control channel or a message of a physical layer service channel.

Step 72, the terminal equipment performs state conversion of the terminal equipment according to the state conversion instruction; wherein the state transition comprises: transitions between main states, transitions between sub-states, and transitions between main states and sub-states; the main state comprises an RRC connected state and an RRC idle state, the sub-states comprise a plurality of states in the RRC connected state, and the terminal equipment can be in only one sub-state at the same time.

In this embodiment of the present invention, when the terminal device needs to send uplink data, the method further includes:

if the terminal equipment is in the weak connection sub-state, initiating a random access process, and sending data after completing air interface link synchronization; and if the terminal equipment is in the discontinuous connection sub-state, transmitting the uplink data by adopting a non-orthogonal transmission mode.

The state control method of the embodiment of the present invention is described above from the network side and the terminal side, respectively. It can be seen that, in the embodiment of the present invention, by newly defining the sub-state in the RRC connection state and controlling the terminal to enter the corresponding sub-state according to the terminal service type, the state of the terminal device can be sunk to the air interface, so that the network side can make a fast response according to the behavior characteristics of the terminal device at the air interface, and thus the requirement of the 5G service can be satisfied.
