Method, device, system and storage medium for activating connection

Technical Field

Embodiments of the present application relate to the field of communications technologies, and in particular, to a method, an apparatus, a system, and a storage medium for activating connection.

Background

In the DC (Dual Connectivity ) scenario, when the amount of data transferred between the terminal device and the secondary node decreases, the connection of the terminal device and the secondary node may be deactivated, so as to achieve the effect of saving the energy consumption of the terminal device. In addition, when the data transmission is needed, the connection between the terminal equipment and the auxiliary node can be activated again (active).

When the terminal equipment in the inactive state has the data transmission requirement again, the connection with the auxiliary node is required to be additionally established, and the terminal equipment can frequently establish and terminate the connection with the auxiliary node under the condition that the terminal equipment is not connected with the auxiliary node because the requirement of the terminal equipment for data transmission is dynamic, so that the power consumption is caused.

The achievement of the objects, functional features and advantages of the present application will be further described with reference to the accompanying drawings, in conjunction with the embodiments. Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. 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.

Firstly, explanation is made on nouns according to embodiments of the present application:

double connection: the terminal equipment is accessed to two different network equipment by adopting the same wireless access technology; alternatively, the terminal device uses two different radio access technologies to access one network device or two network devices simultaneously. Optionally, the connection established between the terminal device and the MN (Master Node) is referred to as MCG (Master Cell Group, primary cell group), and the primary cells in the primary cell group are referred to as PCell; the connection established between the terminal device and the SN (Secondary Node) is called SCG (Secondary Cell Group ), and the primary cell in the Secondary cell group is called PScell. There is a control plane link called Xn-C between the primary node and the secondary node and at least the primary node is connected to the core network via an interface NG-C.

The dual connection includes EN-DC (EUTRA-NR Dual Connectivity) and MR-DC (Multi-Radio Dual Connectivity), multi-radio dual connection.

FIG. 1a is a schematic diagram of an EN-DC scenario. As shown in fig. 1a, the terminal device accesses two base stations simultaneously through the interface Uu: meNB and SgNB. Specifically, the MeNB is a 4G base station that provides S1-MME connection for a terminal device, is connected to a 4G core network as a control plane anchor point, and assumes all control plane functions, and is therefore also referred to as a master node; the SgNB is a 5G base station, there is no control plane link directly connected to the core network, there is a control plane link called X2-C between the SgNB and the MeNB, the SgNB does not assume the control plane function, and the interaction with the control plane of the core network is performed by means of the MeNB, so that it is called as a secondary node.

Fig. 1b is a schematic diagram of a multi-radio dual connectivity scenario. As shown in fig. 1b, the terminal device is configured to access two different nodes via the interface Uu, respectively, and to utilize resources provided by the two different nodes, one node providing a new air interface access and the other node providing E-UTRA or a new air interface access. Alternatively, one node acts as a master node and the other node acts as a slave node. The primary node and the secondary node are connected by a network interface and at least the primary node is connected to the core network. In NGEN-DC (NG-RAN E-UTRA-NR Dual Connectivity), the auxiliary node provides new air interface access, and the main node provides E-UTRA access; in NE-DC (NR-E-UTRA Dual Connectivity), a main node provides new air interface access, and a secondary node provides E-UTRA access; in NR-DC (NR-NR Dual Connectivity), both the primary node and the secondary node provide new air interface access.

In a multi-radio dual connection, the terminal device is configured with two medium access control entities: one medium access control entity for the primary cell group and another medium access control entity for the secondary cell group. The service units of the primary cell group other than the PCell can only be activated/deactivated by control elements in the medium access control protocol data units received on the primary cell group, and the service units of the secondary cell group (except the PSCell) can only be activated/deactivated by control elements in the medium access control protocol data units received on the secondary cell group.

RA (Random Access): refers to the procedure before attempting to access the network device from the time when the terminal device transmits the random access preamble until a basic signaling connection is established with the network device. The terminal device may initiate random access in a number of possible scenarios. For example, after the state of the terminal device is switched from the idle state to the connection state, the terminal device initiates random access when establishing a wireless link process with the network device; or, the state of the terminal device initiates random access when switching from the inactive state to the connected state, etc.

The random access according to the embodiment of the present application may include two-step random access (may also be referred to as 2-step RA) and four-step random access (may also be referred to as 4-step RA), and in order to facilitate understanding, the procedure of the two-step random access and the four-step random access will be described in detail.

Fig. 2 is a schematic flow chart of two-step random access. Referring to fig. 2, the two-step random access may include:

s201, the terminal equipment sends MsgA to the network equipment.

Optionally, the MsgA comprises a random access preamble (preamble) and a payload (payload).

S202, the network equipment sends MsgB to the terminal equipment.

MsgB may be: contention resolution (Contention Resolution), fallback indication (Fallback Indication), or fallback indication (Backoff Indication), etc.

Fig. 3 is a schematic flow chart of four-step random access. Referring to fig. 3, the four-step random access may include:

s301, the terminal equipment sends Msg1 to the network equipment.

Alternatively, msg1 comprises: random access preamble, which may also be referred to as a random access preamble sequence, or preamble sequence.

S302, the network equipment sends Msg2 to the terminal equipment.

Alternatively, msg2 may be: random access response and/or back-off indication. The back-off indication is used to indicate the back-off time for retransmitting Msg1.

For CFRA (Contention Free Random Access, non-contention based random access), after the terminal device successfully receives Msg2, the random access procedure ends. For CBRA (Contention Based Random Access, contention-based random access), after the terminal device successfully receives Msg2, it also needs to continue to transmit Msg3 and receive Msg4.

S303, the terminal equipment sends Msg3 to the network equipment.

Alternatively, msg3 is the first scheduled transmission in the random access procedure, sending a payload (payload).

S304, the network equipment sends Msg4 to the terminal equipment.

Optionally, msg4 is used to indicate whether the terminal device successfully accesses the network device. Msg4 has the effect of resolving competing conflicts. Taking initial access as an example, the conflict is resolved by the terminal device receiving PDSCH (Physical Downlink Shared Channel ) of Msg4, serving data units (Service Data Unit, SDU) by matching CCCH (Common Control CHannel ) in the physical downlink shared channel.

Inactive state: after the terminal equipment finishes the data transmission of the present time, the network equipment does not directly let the terminal equipment release the wireless resource control connection to enter an idle state, but the network equipment configures the terminal equipment to enter an inactive state. After the terminal device enters the inactive state, data transmission is not performed with the network device, but paging from the network device can be periodically received. The network device reserves the configuration of the radio resource control connection, the configuration of the bearer, the security configuration and the parameter configuration related to the terminal device by the n2 interface (interface between the 5G core network and the base station), for example, the primary node configures the primary cell group and the secondary cell (which may be called as "MCG Scell") thereof, the secondary node also configures the secondary cell group and the secondary cell (which may be called as "SCG Scell") thereof, and the like, and the terminal device also needs to save the configuration of the radio resource control connection, the configuration of the bearer, the security configuration and the like. Because the terminal equipment and the network equipment both have the radio resource control connection configuration parameters of the terminal equipment, when the terminal equipment which enters the inactive state has data transmission, the terminal equipment can be quickly accessed into the network equipment to carry out data transmission by utilizing the stored radio resource control connection configuration parameters. In some implementations, the network device instructs the terminal device to enter the inactive state through RRC release signaling.

Radio resource control (connection) recovery procedure: refers to a process that the terminal equipment in the inactive state is re-accessed to the network equipment and returns to the connection state.

In the dual-connection scenario, when the data volume interaction between the terminal device and the auxiliary node is reduced, the connection between the terminal device and the auxiliary node can be deactivated, i.e. the terminal device is in a deactivated state relative to the auxiliary node, so as to achieve the power saving effect. When data transmission is needed, the connection between the terminal equipment and the auxiliary node can be restored.

In some implementations, the connection of the terminal device with the secondary node is activated by:

1. if the auxiliary node has downlink data and needs the auxiliary node to provide resources, the auxiliary node starts an activation connection process by sending an auxiliary node activation request message to the main node.

Or when RLC (Radio Link Control, radio link control layer protocol) bearers corresponding to the DRBs (Data Radio Bearer) are located in the primary cell group and the secondary cell group, if the primary node has downlink data and needs the secondary node to provide resources, the primary node starts an active connection procedure.

2. When the master node receives the auxiliary node activation request message or the master node starts the activation connection process, the master node sends an auxiliary cell group activation command to the terminal equipment;

3. When receiving the activation command of the auxiliary cell group, the terminal equipment replies the main node to send a confirmation;

4. the terminal equipment initiates random access to the auxiliary node;

5. after reporting the CSI (Channel State Information ) report, the terminal device resumes communication with the secondary node.

The flow of the connection between the active terminal device and the auxiliary node is initiated by the main node or the auxiliary node, and is only suitable for the scene that downlink data needs to be transmitted. When the terminal equipment in the inactive state has the data transmission requirement again, extra energy is consumed to establish the connection with the auxiliary node, and meanwhile, the situation that the connection is frequently established and terminated under the condition that the connection is not set is easy to form in consideration of the fact that the requirement of the terminal equipment for the data transmission is dynamic, so that power consumption is caused.

Based on the above problems, the present application provides a method, device, system and storage medium for activating connection, which initiates a process of activating connection between a terminal device and an auxiliary node through the terminal device, so as to effectively recover connection between the terminal device and the auxiliary node, thereby meeting the requirements of power saving and energy saving and/or quick connection establishment.

The method for activating connection provided by the embodiment of the application can be applied to the communication system architecture schematic diagram shown in fig. 4. As shown in fig. 4, the communication system includes: AMF/UPF, access network equipment and terminal equipment. Optionally, the access network device includes: a first base station and a second base station. Illustratively, the first base station and the second base station are both base stations of the new air interface system. In the scenario shown in fig. 4, the first base station and the second base station share one AMF/UPF, alternatively, the first base station is connected to an AMF (Access and Mobile Management Function, access and mobility management function)/UPF (User Plane Function ) core network device through an interface NG-C, the first base station is connected to the second base station through an interface X2-C, and the terminal device accesses the first base station and the second base station simultaneously. Of course, in other scenarios, the first base station and the second base station may also have separate AMFs/UPFs, which are not limited in this embodiment of the present application.

It should be noted that the communication system shown in fig. 4 may be applicable to different network systems, for example, GSM (Global System of Mobile communication, global system for mobile communications), CDMA (Code Division Multiple Access ), WCDMA (Wideband Code Division Multiple Access, wideband code Division multiple access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, time Division synchronous code Division multiple access), long term evolution system, and future 5G network systems. Alternatively, the communication system may be a system in a scenario of high reliability and low latency communication in a 5G communication system.

The terminal device may be a wireless terminal device or a wired terminal device. The wireless terminal device can be a device with wireless receiving and transmitting function, which can be deployed on land, including indoor or outdoor, hand-held or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal device may be a mobile phone (mobile phone), a tablet (Pad), a computer with a wireless transceiving function, a VR (Virtual Reality) terminal device, an AR (Augmented Reality ) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned driving (self driving), a wireless terminal device in remote medical (remote medical), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), a wearable device, and the like, which are not limited herein.

In some implementations, the following embodiments of the application may be applied, for example, to the following scenarios:

example scenario one: when a user browses videos by using the terminal equipment, application software related to the videos in the terminal equipment can firstly download a certain amount of data to be cached in the terminal equipment, so that user experience is smoother. And stopping downloading the data after the cached data quantity reaches the preset upper threshold, and continuing to download until the cached data quantity reaches the preset upper threshold after the cached data quantity is smaller than the preset lower threshold, so that the operation is repeated. The terminal equipment obtains the auxiliary node activation condition parameters, sends an auxiliary node activation request according to a preset rule to obtain auxiliary node activation response, activates the connection between the terminal equipment and the auxiliary node according to the auxiliary node activation response, and accordingly accelerates the completion of downloading; on the contrary, when the data transmission quantity is smaller, the connection between the terminal equipment and the auxiliary node can be deactivated, so that the power saving and energy saving effects are achieved.

Example scenario two: when a user sends a short video, a document, a picture or a data connection request through application software in terminal equipment, such as a game. When the transmission is finished or the data volume of the transmission is reduced, the connection between the terminal equipment and the auxiliary node can be deactivated, so that the power and energy saving effects are achieved.

The following describes embodiments of the present application and how the technical solutions of the present application solve the above technical problems in detail. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 5 is a signaling interaction schematic diagram of a method for activating a connection according to an embodiment of the present application. As shown in fig. 5, the method of the present embodiment includes the steps of:

s10, acquiring the auxiliary node activation condition parameters.

When the terminal equipment in the inactive state has the data transmission requirement again, the terminal equipment acquires the auxiliary node activation condition parameters.

Alternatively, the "acquiring" in this step may include acquiring from inside the terminal device or acquiring from the network device. Specifically, the auxiliary node activation condition parameters may be pre-stored in the terminal device, so that the auxiliary node activation condition parameters may be obtained from the inside of the terminal device. Alternatively, the step may be specifically: the terminal equipment receives the auxiliary node deactivation indication information, and optionally, the auxiliary node deactivation indication information carries auxiliary node activation condition parameters, and the deactivation indication information is used for deactivating the connection between the terminal equipment and the auxiliary node.

It can be understood that after receiving the auxiliary node deactivation indication information, the terminal device stores the auxiliary node activation condition parameters carried in the auxiliary node deactivation indication information, so that the auxiliary node activation condition parameters can be obtained from the inside of the terminal device when the connection between the terminal device and the auxiliary node is subsequently activated.

Optionally, the deactivation indication information may include at least one of: radio resource control signaling, control elements in medium access control protocol data units or downlink control information, etc. The downlink control information may be embodied as information indicated by control elements on PDCCH (Physical Downlink Control Channel ) and/or PDSCH (Physical Downlink Shared CHannel, physical downlink shared channel), for example.
