1 is an architectural diagram of a mobile communication system in the related art. As shown in FIG. 1, the mobile communication system function is divided into three logical functional entities, including a core network (Core Network, referred to as CN), and a base station (BS). And a mobile station (Mobile Station, MS for short), wherein the CN supports a network-side non-access stratum-related function, the BS supports a network-side radio access network function, and the MS supports a peer-to-peer function corresponding to the CN and the BS; further The CN and the BS are connected by a logical interface (including various wired networks and possibly wireless networks), which is called a CN-BS connection. The BS and the BS are connected by a logical interface (including various wired networks and possibly wireless networks), which is called a BS-BS connection; the BS and the MS are connected by a wireless interface, which is called a BS-MS connection. Specifically, the logical function entities may be implemented by one or more actual functional entities. Correspondingly, the logical interfaces are connected by multiple physical interfaces, for example, multiple CN functional entities form a core network, and multiple BS functional entities form a wireless connection. On the network side. 2 is an architecture diagram of an LTE system in the related art. As shown in FIG. 2, the CN includes two functional entities: an MME (control plane) and an SGW (user plane). The BS corresponds to an eNB functional entity, and the MS corresponds to the UE function. entity. The eNB and the MME and the SGW are respectively connected through an S1-C (control plane connection) and an S1-U (user plane connection) interface, and the eNB and the eNB are connected through an X2 interface, and the eNB and the UE are connected through the Uu interface. These interface connections usually correspond to some resource configuration and management related information. The Uu interface connection is managed and maintained by the eNB and the UE, the X2 interface is managed and maintained by two related eNBs, and the S1-C and S1-U connections are managed and maintained by the eNB and the MME.

In the wireless access system of the mobile communication system, different RRC management states are usually defined according to the functions supported by the terminal and the resource configuration. For example, in the LTE system, FIG. 3 is a schematic diagram of a conversion relationship between two states of RRC idle and RRC connected in the related art. As shown in FIG. 3, it defines two states of RRC idle and RRC connected and transition between two states. Relationship, where:

The main features of the UE in the RRC idle state include:

The network side of the radio access network, that is, the eNB does not have any information of the UE, nor does it establish any dedicated connection and allocate any dedicated resources for the UE on the S1-C, S1-U and Uu interfaces;

The UE autonomously performs mobility management between cells according to configuration information in the eNB system information;

If there is data to be sent to the UE from the network side point-to-point, the CN needs to initiate a paging procedure for the UE. After receiving the paging message, the UE initiates a series of processes and messages are switched to the RRC connected state to establish Uu, S1- C, S1-U, etc. are connected, and then can receive downlink data; if the UE needs to send a little bit of uplink data, it initiates a series of processes and messages to the RRC connected state, and establishes Uu, S1-C, S1-U and other connections. , then you can send upstream data.

The main functional features of the UE in the RRC connected state include:

The network side of the radio access network, that is, the eNB establishes a dedicated connection for the UE on the S1-C, S1-U, and Uu interfaces and allocates dedicated resources. These dedicated connections and their associated resource configuration information are used by the eNB with the UE context (UE). The context is preserved, managed, and maintained.

The mobility management of the UE between cells is controlled by the eNB;

The UE may receive the point-to-point downlink data or send the uplink data through a dedicated resource;

Due to the above-mentioned functional features of the two states of RRC idle and RRC connected, the UE has the following performance characteristics in the two states and in the state transition:

In the RRC idle state, the UE can maintain the energy-saving state most of the time because it only needs to listen to signals sent by few eNBs.

In the RRC connected state, the UE needs to relatively monitor the signal sent by the eNB because of the need to maintain the Uu interface connection, and the power consumption is relatively large;

In order to save power consumption of the UE, the UE switches between the RRC idle and RRC connected states under the control of the eNB;

The transition between the RRC idle and RRC connected states needs to be completed through a series of S1-C, S1-U, and Uu interfaces and their messages, so there is a relatively large state transition delay. At the same time, more signaling overhead is generated.

Based on the requirements of the above 5G, the functional characteristics and performance characteristics of the two RRC idle and RRC connected UE states defined in the LTE system, especially the large state transition time and large signaling overhead, are in the 5G wireless access system. A new RRC state may be introduced, which is between the RRC idle and RRC connected states, and may be referred to as an RRC inactive state (but does not exclude other supported functions and resource configurations having the same or similar names). The status will have some characteristics of RRC idle and RRC connected, including: (Note: The following description refers to the 5G core network as CN, the radio access network functional entity as eNB, and the mobile terminal as UE, but does not exclude other Functionally the same or similar name)

The network side of the radio access network, that is, the eNB retains (or stores) all or part of the resource configuration information of the S1-C, S1-U interface dedicated connection established by the UE in the UE context (UE context) in the RRC connected state, Or retain the S1-C, S1-U interface dedicated connection (including the relevant resources and corresponding configuration information in the UE context); release some resources of the dedicated connection of the Uu interface and configuration information in the UE context, especially the dedicated wireless of the Uu interface Resources and their configuration information, other Uu interface dedicated connection related resources and configuration information in the UE context are reserved;

The UE autonomously performs inter-cell mobility management according to configuration information (from system information or other RRC messages) in a predefined or pre-configured area; when the UE moves out of the predefined or pre-configured area, it may be referred to as a paging area. Paging area (not excluding other similar names), the UE needs to notify the radio access network side in some way; wherein the paging area may include one or more cells, and multiple cells may belong to one eNB, or may belong to different eNB.

As shown by the thin solid lines and arrows between the RRC connected, RRC inactive, and RRC idle states, these states may be set and released due to RRC connection setup, specific timers are set to expire, dedicated RRC commands, data reception or transmission, etc. A state transition occurs because of a series of process and information interactions.

In particular, in the downlink direction, the base station can only reach the terminal at the paging occasion, that is, if there is data to be sent from the network side to the UE, the CN directly sends the data to the eNB, and the eNB initiates a paging procedure for the UE, and the UE After receiving the paging message, the process initiates a series of processes and the message is switched to the RRC connected state, and the Uu, S1-C, and S1-U connections are established or restored, and then the downlink data can be received; and in the uplink direction, the terminal can only receive the random connection. If the UE is connected to the base station, the UE needs to send a series of processes and messages to the RRC connected state through the random access procedure, and establish or restore the Uu, S1-C, S1-U, and the like. Then you can send upstream data.

That is, the UE in the RRC inactive state in the related art cannot directly receive downlink data or send uplink data, but can receive downlink data or send uplink only when transitioning to the RRC connected state. Data, in the current and subsequent predictable mobile Internet services, non-frequent small data packet services will account for a relatively large proportion. In the above-mentioned manner, there is a problem of large transmission delay and large signaling overhead of infrequent small data packet services.

The UE in the RRC inactive state in the related art cannot directly receive downlink data or send uplink data. Currently, no effective solution has been proposed.
