step 201, if RRC connection is established with a ue, allocating an identifier to the ue, wherein different ues in the same network side notification area are allocated with different identifiers.

The RRC connection established with the ue in this step may be understood as that, in the process of establishing the RRC connection between the ue and the network side device, or the ue and the network side device have already completed the RRC connection, or the network side device releases the RRC connection with the ue, that is, in step 201, an identifier may be allocated to the ue in the process of establishing the RRC connection between the ue and the network side device, or when the RRC connection between the ue and the network side device has already completed the RRC connection, or in the process of releasing the RRC connection with the ue by the network side device.

Step 202, sending the identifier to the user terminal.

The step 202 may be the identifier sent to the user terminal when the user terminal is in the connected state, which is not limited, for example: the identifier may be transmitted to the user terminal in another state.

The identifier may be unique to all cells in a network side notification area configured for the ue at the network side, and different ues may have different identifiers in the same network side area. Thus, when the user terminal is in the inactive state, the user terminal can be identified in the network side notification area through the identifier.

In the embodiment of the present invention, the ue in the inactive state may have at least one of the following characteristics:

mobility is achieved through cell reselection;

the anchoring network side equipment of the user terminal keeps the control plane and the user plane connection from the radio access network side of the user terminal to a core network (CN-NRRAN) (namely keeps the user plane and the control plane connection similar to S1 in LTE);

at least one network side device stores the context information of the user terminal, namely the network side device which at least keeps the connection of the control plane and the user plane from the wireless access network side to the core network (CN-NR RAN) of the user terminal stores the context information of the user terminal;

the notification to the user terminal is initialized by the radio access network side (NR RAN), so the network side notification area is managed by the NRRAN, and the NR RAN knows to which network side notification area the user terminal belongs.

In this embodiment of the present invention, the network side notification area may be managed by a radio access network side (NR RAN), and the network side notification area may include one or more cells, which may specifically be determined by a network side device; in addition, a notification for the user terminals in the network side notification area is initiated by the radio access network side (NR RAN). In addition, in the embodiment of the present invention, the network side notification area may also be referred to as a notification area or a notification management area, and is specifically an area including one or more cells and determined by a radio access network side (NR RAN).

This allows the user terminal to be assigned an identifier that applies to the inactive state, and since the identifier that applies to the inactive state is defined, the user terminal can be accurately identified in the network-side notification area, thereby improving the performance of the communication system.

Second embodiment

Referring to fig. 3, fig. 3 is a flowchart of an identifier definition method of a user terminal according to an embodiment of the present invention, where the method is applied to a network side device, as shown in fig. 3, and includes the following steps:

step 301, if RRC connection is established with a ue, allocating an identifier to the ue, wherein different ues in a same network side notification area are allocated with different identifiers.

Establishing the RRC connection with the ue in this step may be understood as that, in a process of establishing the RRC connection between the ue and the network side device, or in a process of completing the RRC connection between the ue and the network side device, or in a process of releasing the RRC connection with the ue by the network side device, that is, in step 201, an identifier may be allocated to the ue in a process of establishing the RRC connection between the ue and the network side device, or in a process of completing the RRC connection between the ue and the network side device, or in a process of releasing the RRC connection with the ue by the network side device.

Step 302, sending said identifier to said user terminal.

Optionally, in an embodiment of the present invention, the identifier is represented by a plurality of bits; or the Identifier includes a Cell Radio Network Temporary Identifier (C-RNTI) and a Cell identity of the ue.

For example, the identifier may be expressed by 16 bits, 28 bits, or 30 bits. The identifier may include the C-RNTI and the cell identity of the user terminal, and may be formed by combining the C-RNTI and the cell identity of the LTE system. Therefore, when the user terminal is in an inactive state, the user terminal can recognize the user terminal C-RNTI and the cell identifier, so that the accuracy of recognizing the user terminal is improved.

It should be noted that, in this embodiment of the present invention, without special description, the identifiers provided in this embodiment of the present invention all satisfy the requirement that all cells in the network side notification area configured for the user terminal on the network side have uniqueness, and the characteristic of identifying the user terminal when the user terminal is in an inactive state.

Optionally, the step of sending the identifier to the user terminal includes: and sending the identifier to the user terminal through physical layer signaling, Media Access Control (MAC) layer signaling or RRC signaling.

Of course, in the embodiment of the present invention, the identifier is not limited to be sent through physical layer signaling or MAC layer signaling, and may also be sent through other signaling, for example: other connection status signaling, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the identifier may be applied to a paging message, so as to add the identifier field to identify different ues in a network side notification area in the paging message for an inactive ue. And the user terminal can carry the user terminal identifier when initiating the network side notification area updating request, so that the network side equipment can distinguish different user terminals in the network side notification area by using the identifier. And the user terminal can carry the user terminal identifier when sending the uplink data, so that the network side equipment can distinguish different user terminals in the network side notification area by the identifier. It should be noted that, in the embodiment of the present invention, the identifier is not limited to be used in the three scenarios, and the identifier may be used in any other inactive scenario to identify the user terminal.

Step 303, if RRC connection is established with the ue, reconfiguring a new identifier for the ue.

The network side notification area update of the ue may be that the network side device reconfigures the network side notification area information to the ue according to the characteristics of the ue, where the network side notification area is reconfigured to meet the characteristics of the ue or to match the characteristics of the ue with a higher degree. The user terminal characteristics may be service information of the user terminal or a moving speed of the user terminal, and the embodiment of the present invention is not limited thereto.

In addition, it should be noted that, in the embodiment of the present invention, updating the network side notification area of the ue may also be understood as updating the network side notification area information of the ue, because in the updating process, the network side update area information stored in the ue and the network side device may be updated.

Optionally, the step of determining whether the network side device notification area of the user terminal needs to be updated includes: after detecting that the user terminal is subjected to cell switching, judging whether the cell where the user terminal is located is in the network side notification area or not; if the cell where the user terminal is located is not in the network side notification area, determining that the network side equipment notification area of the user terminal in a connection state needs to be updated; and if the cell where the user terminal is located is in the network side notification area, determining that the network side equipment notification area of the user terminal in the connection state does not need to be updated.

Through the steps, the user terminal can move, after the cell switching occurs, the cell where the user terminal is located is not in the network side notification area configured to the user terminal by the network side equipment, the network side equipment updates the network side notification area information of the user terminal, and reconfigures the identifier of the user terminal, so that the user terminal can update the identifier of the user terminal in time after the cell switching occurs, the service transmission of the user terminal is prevented from being influenced, and the service performance of the user terminal is improved. In addition, if the network side notification area information of the user terminal does not need to be updated, the identifier of the user terminal is not updated.

Step 304, sending the new identifier to the user terminal.

The step 304 may be implemented to update the identifier of the user terminal to ensure service delivery of the user terminal.

It should be noted that, in the embodiment of the present invention, step 303 and step 304 are replaceable, for example: in the embodiment of the present invention, the identifier of the user terminal may also be updated when the user terminal is in an inactive state. For example, as follows:

Optionally, in this embodiment of the present invention, the step of sending the new identifier to the user terminal includes:

sending the new identifier to the user terminal via a random access response message or random access message 4(Msg 4).

Since the new identifier can be sent to the ue in the random access procedure through the random access response message or the message 4, no additional message needs to be added to save transmission resources.

Optionally, in this embodiment of the present invention, after the step of sending the identifier to the user terminal, the method further includes: if the user terminal is in an inactive state and is switched to an RRC connected state from the inactive state, reconfiguring a new identifier for the user terminal; sending the new identifier to the user terminal.

If the ue is in the inactive state and is switched from the inactive state to the RRC connected state, the new identifier may be reconfigured for the ue when the network side device detects the ue in the inactive state and switches from the inactive state to the RRC connected state. Or the ue is in an inactive state and is transitioned from the inactive state to an RRC connected state, the reconfiguring the new identifier for the ue may be receiving an identifier update request sent by the ue through the identifier in the connected state after the ue is transitioned from the inactive state to the connected state; and reconfiguring the identifier for identifying the user terminal when the user terminal is in an inactive state based on the identifier updating request to obtain a new identifier of the user terminal.

Through the steps, the user terminal can be forwarded to the connection state from the non-activation state so as to request to update the identifier for identifying the user terminal when the user terminal is in the non-activation state, so that the flexibility of updating the identifier of the user terminal is improved, and the diversification of future communication services and requirements is adapted. Here, the updating may be updating to obtain the new identifier by using an update procedure for updating the identifier of the user terminal in the connected state.

This allows the user terminal to be assigned an identifier that applies to the inactive state, and since the identifier that applies to the inactive state is defined, the user terminal can be accurately identified in the network-side notification area, thereby improving the performance of the communication system. And the identifier of the user terminal can be updated in time so as to accurately identify the user terminal in each network side communication area.
