Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application, where the communication system includes a network device and a user equipment. As shown in fig. 1, a network device may communicate with a user device. The communication system may be a global system for mobile Communication (CSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a Worldwide Interoperability for Microwave Access (WiMAX) system, a Long Term Evolution (LTE) system, a 5G communication system (e.g., new radio, NR)), a communication system in which a plurality of communication technologies are merged (e.g., a communication system in which an LTE technology and an NR technology are merged), or a communication system in which a subsequent evolution is performed. The form and number of the network devices and the user devices shown in fig. 1 are only examples, and do not limit the embodiments of the present application.

The user equipment in the application is a device with a wireless communication function, and can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The user equipment may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), and the like. The user device may also be a handheld device with wireless communication capabilities, a vehicle mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, etc. The user devices may be called different names in different networks, for example: a terminal device, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or user equipment, a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) telephone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a terminal device in a 5G network or a future evolution network, etc.

The network device in the present application is a device deployed in a radio access network to provide a wireless communication function. For example, the Network device may be a Radio Access Network (RAN) device on an Access Network side in a cellular Network, and the RAN device is a device for accessing a user equipment to a wireless Network, and includes but is not limited to: evolved Node B (eNB), radio Network Controller (RNC), node B (NB), base Station Controller (BSC), base Transceiver Station (BTS), home Base Station (e.g., home evolved Node B, or Home Node B, HNB), base Band Unit (BBU), management Entity (Mobility Management Entity, MME); for another example, the Network device may also be a node device in a Wireless Local Area Network (WLAN), such as an Access Controller (AC), a gateway, or a WIFI Access Point (AP); for another example, the network device may also be a transmission node or a transmission reception point (TRP or TP) in the NR system.

In a 5G network environment, a new RRC state, i.e., an RRC INACTIVE (INACTIVE) state, is defined for the purposes of reducing air interface signaling, quickly recovering radio connection, and quickly recovering data service. The RRC inactive state is different from an RRC IDLE (IDLE) state and an RRC connected state.

RRC idle state: there is no RRC connection, mobility is based on cell selection reselection of the user equipment, paging is initiated by a Core Network (CN), a paging area is configured by the CN, and the Network equipment does not have an Access Stratum (AS) context of the user equipment.

RRC connected state: the RRC connection exists, the network device and the user equipment exist in a user equipment AS context, the network device knows that the location of the user equipment is represented by a specific cell level, mobility is controlled by the network device, and unicast data can be transmitted between the user equipment and the network device.

RRC inactive state: mobility is cell selection reselection based on user equipment, a connection between a CN and a New air interface (New Radio, NR) exists, a user equipment AS context exists on a certain network equipment, paging is triggered by RAN, a paging area based on RAN is managed by RAN, and the network equipment knows that the location of the user equipment is based on the paging area level of RAN.

The network device may control state transitions of the user device.

In the RRC inactive state, the user equipment autonomously returns to the RRC idle state in at least one of:

1) When receiving the initial paging message of CN;

2) When an RRC recovery request is initiated, a timer T319 is started, and if the timer is overtime;

3) When the integrity protection verification of the message (MSG 4) in the fourth step in the random access process fails;

4) When a cell reselects to other Radio Access Technology (RAT);

5) And entering a state of residing in any cell (camp on any cell).

The features of the RRC inactive state include at least one of:

1) The connection between RAN and CN is maintained;

2) The user equipment and at least one network equipment save the AS context;

3) The user equipment is reachable to the RAN side, and the relevant parameters are configured by the RAN;

4) The network device does not need to be notified when the user equipment moves within a RAN Notification Area (RNA) configured by the RAN, but needs to be notified when the RNA moves out;

5) The user equipment moves within the RNA in accordance with the cell selection reselection mode.

The network device may use an RRC Release (Release) message to transition the ue from the RRC connected state to the RRC Inactive state or from the RRC Inactive state to the RRC Inactive state, if the RRC Release message carries a suspend configuration (suspendConfig). Before the user equipment enters the RRC inactive state, the network device may configure, through RRC release dedicated signaling, RRC inactive configuration parameters for the user equipment, where the main parameters include at least one of:

1) An Invalid Radio Network temporary Identity (I-RNTI) for identifying the user equipment non-activated context of the user equipment at the Network equipment side, which is unique in the Network equipment;

2) RNA, which is used for controlling the area for cell selection and reselection of the user equipment in the inactive state and is also the paging range area of RAN initial paging;

3) A Discontinuous Reception (DRX) cycle (cycle) of the RAN, configured to calculate a paging occasion for RAN initial paging;

4) A RAN Notification Area Update (RNAU) period (periodicity) for controlling a period in which the user equipment performs periodic RAN location Update;

5) Next hop link count (NCC) is used for the key used in the RRC connection recovery procedure.

When the user equipment moves in the RNA region, the network equipment side is not required to be informed, and the mobility behavior in the RRC idle state, namely the cell selection and reselection principle, is followed. When the user equipment moves out of the paging area configured by the RAN, the user equipment is triggered to recover RRC connection and reacquire the paging area configured by the RAN. When downlink data arrives at the user equipment, the connection between the RAN and the CN is kept for the user equipment, and the network equipment triggers all cells in a RAN paging area to send paging messages to the user equipment, so that the user equipment in an inactive state can recover RRC connection to receive the data. The user equipment in the inactive state configures a RAN paging area, and in the area, in order to ensure the reachability of the user equipment, the user equipment needs to perform periodic location update according to a network configuration period.

So the scenarios that trigger the user equipment to perform RNA updates are: RNAU timer times out (Periodic RNAU-TimerValue), or the user equipment moves to an area outside the RNA.

Currently, for sending uplink small data packets, only one small data packet is supported to be transmitted, for example, a small data packet may be carried in the third step message (MSG 3) in the random access procedure. However, in practice, there may be a plurality of consecutive small packets in the ue, and in order to transmit these small packets, the ue needs to frequently use the RACH procedure to transmit these small packets in MSG3, or the network device switches the ue from the RRC inactive state to the RRC connected state, recovers the user plane Bearer (DRB), and then transmits these small packets. The first transmission mode may cause frequent RRC state switching, increasing signaling overhead. The second transmission method is to let the ue enter the RRC connected state to transmit data, which increases the RRC signaling overhead and also increases the power consumption of the ue.

Referring to fig. 2, fig. 2 is a schematic flowchart of a communication processing method according to an embodiment of the present application, including the following steps:

step 201: in an RRC inactive state, the user equipment transmits a first data packet by using the activated semi-static configuration resource, wherein the size of the first data packet is smaller than or equal to a first threshold value.

The first threshold may be N bits, and N may be 1000 or another value.

The number of the first data packets may be one or more, and is not limited herein.

It should be noted that, in the RRC inactive state, if there is a second data packet, the ue may also transmit the second data packet using the activated semi-static configuration resource, and the size of the second data packet is greater than the first threshold.

Optionally, the configured semi-statically configured resource is configured by the network device to the user equipment in an RRC inactive state, or the configured semi-statically configured resource is configured by the network device to the user equipment in an RRC connected state.

Specifically, in the RRC inactive state, the manner for the network device to configure the semi-static configuration resource for the user equipment specifically includes: in an RRC inactive state, the ue sends an RRC recovery request message to the network device, and then the network device replies an RRC release message to the ue after receiving the RRC recovery request message, where the RRC release message may carry configuration information of the configured semi-static configuration resource.

In the RRC connected state, the manner of configuring the semi-static configuration resource for the user equipment by the network equipment specifically includes: in the RRC connected state, the network device sends an RRC release message to the user equipment, where the RRC release message is used to instruct the user equipment to release to an RRC inactive state, and the RRC release message may carry configuration information of the configured semi-static configuration resource.

In an implementation manner of the present application, if the second information indicates that the configured semi-static configuration resource is activated, the second RRC release message further includes fourth information, where the fourth information is used to indicate an activation duration of the activated semi-static configuration resource.

Alternatively to this, the first and second parts may, the first timer includes T380.

Specifically, when the ue receives the first RRC release message and confirms activation of the semi-static configuration resource, the ue starts the first timer; during the running of the first timer, the semi-static configuration resource is in an activated state; when the first timer expires, if the ue wants to continue using the semi-persistent configuration resource, the ue needs to re-initiate the RRC recovery procedure. If the user equipment does not want to continue using the semi-statically configured resources, the user equipment does not need to initiate an RRC recovery procedure.

In an implementation manner of the present application, before step 301, the method further includes:
