Background

In a cellular system, when a terminal accesses a cell under a base station to perform data transmission, the base station needs to perform access control on the terminal. The basic access control includes two aspects:

firstly, the base station broadcasts admission Control parameters of a cell to Control the Access of terminals with different Access levels, and the terminals judge whether to initiate connection establishment to the cell according to the admission Control parameters, specifically, the base station sends UAC (Unified Access Control) parameters, mainly Access level AC category lists and Access factors of each Access level.

Secondly, in the process of establishing connection between the terminal and the base station, including the processes of connection establishment, connection recovery and the like, the terminal carries a reason (cause) in the request initiated to the base station, for example, ResumeCause in the connection recovery request is as follows, and the establishmencause of the connection establishment request includes all reasons except "rn-Update" in the following list.

ResumeCoose: (ENGMERATED { emergency, highPriorityAccess, mt-Access, mo-Signalling)

mo-Data, mo-VoiceCall, mo-VideoCall, mo-SMS, rna-Update, mps-PriorityAccess, (mo Data, mo voice call, mo video call, mo SMS, rna Update, mps priority access)

MCS-priority access, spare1, spare2, spare3, spare4, spare5(MCS priority access, spare1, 2, 3, 4, 5) }

Generally speaking, a terminal is accessed based on a single cell, and only whether a cell and a core network unit corresponding to the base station can provide service for the terminal needs to be considered in the process of establishing connection between the base station and the terminal. And in the process of establishing the connection, the granularity of the service meeting consideration is very coarse, and the more specific service requirement is not considered.

Detailed Description

The inventor notices in the process of invention that:

future communication networks will introduce a variety of new services, such as HTC (holographic-type communications). The features of holographic services generally include:

1) the transmission rate requirement is high, and the Tbps level is achieved;

2) the time delay requirement is strict and reaches between millisecond and microsecond;

3) the transport stream comes from a plurality of remote nodes to form a holographic presentation.

Holographic services cannot be seen as a new multimedia type but as a combination of a plurality of independent holographic data streams. The combination of multiple data streams sent to the terminal by access network nodes from different locations can form the presentation of the holographic service at the user side. To achieve this, each data flow has strict requirements on time delay, reliability and synchronization, and the terminal needs to access multiple access network nodes simultaneously to receive and transmit data. The cell access mode of the existing cellular network cannot meet the requirement of novel high-rate service.

Therefore, based on the characteristics of the new services, such as the holographic services, the cell access method of the existing cellular network cannot meet the requirements of the new high-rate services. For example, even if the terminal accesses as a high priority, the network may not be able to provide the high rate low latency requirements of the holographic service although the terminal accesses the cell.

Based on this, the technical solution provided by the embodiment of the present invention will solve the problem that a new type of high-rate service, such as a scheme how a high-rate terminal accesses a network after a holographic service is introduced into a future communication system, such as 6G, so as to provide a required high-data-rate service.

The following describes embodiments of the present invention with reference to the drawings.

In the description process, the implementation of the UE and the base station will be described separately, and then an example of the implementation of the UE and the base station in cooperation will be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such an explanation does not mean that the two must be implemented in cooperation or separately, and actually, when the UE and the base station are implemented separately, the UE and the base station solve the problems of the UE side and the base station side respectively, and when the UE and the base station are used in combination, a better technical effect is obtained.

Fig. 1 is a schematic flow chart of an implementation process of an access method on a terminal side, as shown in the figure, the implementation process may include:

step 101, a terminal determines each access network node related to a service needing to be accessed, wherein each access network node participates in data transmission of a part of the service;

and 102, establishing connection between the terminal and each access network node.

Fig. 2 is a schematic flowchart of an implementation process of an access method at an access network node side, as shown in the figure, the implementation process may include:

step 201, an access network node broadcasts an admission parameter, wherein the admission parameter indicates a sub-service flow type or a service type, wherein the sub-service flow of the sub-service flow type is a part of the service flow of the service type, and each access network node participates in data transmission of a part of the service;

step 202, when the access network node initiates connection at the terminal, if the admission parameter indicates the sub-service flow type, after the terminal is accessed, the access network node transmits the sub-service flow with the terminal; if the admission parameter indicates the service type, after the terminal is accessed, the service flow is transmitted to the terminal by cooperating with each access network node which transmits the sub-service flow with the terminal.

Specifically, the Access network node may be a base station, or a node having a base station function (e.g., managing one or more cells, establishing a unique air interface identifier with a terminal, and performing air interface data transmission with the terminal), such as a CU (Centralized Unit), a DU (Distributed Unit), a relay node, an IAB node (IAB donor node; IAB: Integrated Access and Backhaul), an IAB node (IAB node), and the like.

One or more access network nodes control the access of the terminal, and different access network transmission points cooperate with the terminal to perform data transmission of the same novel service. This is not only for reducing the transmission rate of a single access network node, but for example, in HTC service, holographic service naturally requires that different traffic flows of the same service come from different transmission points, and has a co-flow concept.

In the implementation, the HTC service will be mainly described as a representative of a new service, because the HTC service is typical, the HTC service is taken as an example here; however, other services are also possible as long as this type of service requires multiple access network nodes to provide data transmission to the terminal, and the HTC service is only used to teach those skilled in the art how to implement the present invention specifically, but not to mean only HTC service, and the implementation process may be combined with practical needs to determine a corresponding new type of service.

Specifically, the service of the new service type is split into a plurality of sub-service flow types, and the splitting manner may be as follows: splitting different sub-service flow functions, different sub-service flow transmission positions, different sub-service flow transmission rates and/or time delay requirements and the like.

For the access network node side, the access network node cooperates with each access network node to establish connection with the terminal based on a CA and/or DC mode; or the like, or, alternatively,

In particular, the terminal may access one or more access network nodes simultaneously. The terminal can access a plurality of access network nodes based on a CA (carrier aggregation) and/or DC (Dual Connectivity) mode; or, establishing connections with multiple access network nodes independently,

in specific implementation, when the terminal establishes connection with each access network node respectively:

the terminal and each access network node respectively establish an air interface unique identifier which can be the same or different at each access network node for respective independent control and transmission.

On the side of the access network node, when each access network node establishes connection with the terminal:

when the terminal establishes connection with the network side from an idle state or an inactive state, each access network node establishes RRC connection with the terminal; and/or the presence of a gas in the atmosphere,

In specific implementation, the method may further include:

the terminal initiates deletion or addition of a participating access network node according to the change of the service condition, correspondingly releases and deletes the RRC connection of the access network node, and establishes the RRC connection with the added access network node; or

And the terminal deletes or adds the participating access network nodes according to the indication of the network side node, correspondingly releases and deletes the RRC connection of the access network nodes, and establishes the RRC connection with the added access network nodes.

Specifically, when the terminal establishes a connection with the network side from an idle state or an inactive state, the terminal may directly establish an RRC (Radio Resource Control) connection with multiple access network nodes (or cells);

each access Network node (or Cell) can establish an air interface unique Identifier with the terminal, such as a C-RNTI (Cell-Radio Network Temporary Identifier) which is independently controlled and transmitted, and the air interface unique identifiers can be the same or different in a plurality of access Network nodes (cells) accessed by the terminal; if the terminal is the same, the same C-RNTI is distributed to a plurality of cells for one terminal, and the terminal is known to be the same, so that the service data can be conveniently and cooperatively transmitted.

A plurality of access network nodes connected with the terminal can have no main and auxiliary division, and along with the change of service conditions, the access network nodes can be deleted or added without influencing the RRC connection relation with other access network nodes.

The implementation of the access phase is explained below.

First, admission Control (Access Control).

when the received admission parameters are broadcasted by a plurality of access network nodes, determining each access network node which needs to be accessed and is related to the service according to the sub-service stream type indicated by the admission parameters broadcasted by each access network node; or the like, or, alternatively,

when the received admission parameter is broadcast by an access network node, determining the accessible access network node corresponding to the service type which needs to be accessed according to the indication of the access network node, and determining other access network nodes participating in transmission after the terminal determines to access the access network node of the broadcast admission parameter.

1. When the received admission parameters are broadcast by a plurality of access network nodes.

Specifically, different Access network nodes bear different sub-service flow types, and broadcast admission parameters, such as Access Category parameters of different admission levels, according to the bearable sub-service flow types.

The admission parameters may be unified, for example, ACx is used to represent the holographic service, specifically, which sub-service flow type of the holographic service is coordinately controlled by the network side, and the terminal only needs to determine that a plurality (e.g., N or more) access network nodes satisfying the access condition can admit the service of the access type HTC. And coordinating among the access network nodes the sub-service flow type data which needs to be transmitted with the terminal.

Each access network node broadcasts different admission parameters according to the type of the sub-service flow to be transmitted, the admission parameters are independent, and after the admission parameters of a plurality of access network nodes are combined, a complete new service is represented; or the admission parameters are broadcast according to a sub-parameter mode, for example, ACx-1 to N indicate different sub-service flow types of the holographic service, the terminal needs to access an access network node containing a plurality of required subsets, and only one access network node with the same subset number can be accessed. In this way, the type of sub-traffic that a single access network node can transmit is determined.

2. When the received admission parameters are broadcast by an access network node.

The single access network node (main access network node) undertakes the admission function, the access network node broadcasts the admission parameters of the new service (such as holographic service), if the terminal accesses the network based on the admission parameters, the access network node coordinates other access network nodes which simultaneously provide the new service to establish connection with the terminal and carry out transmission. Lists may be pre-established between access points that may be transmitting new traffic simultaneously.

And secondly, establishing connection.

For connection establishment of an idle or inactive terminal, the terminal may establish RRC connection with one or more access network nodes, respectively.

when the received admission parameters are broadcast by a plurality of access network nodes, the terminal respectively sends connection requests to the access network nodes needing to be accessed, wherein the requests carry one of the following cases or the combination thereof: the service type, the sub-service flow type of the service type, the service type quality-reducing transmission request and the service type quality-reducing transmission request of the sub-service flow type; or the like, or, alternatively,

According to the specifically introduced new service type, the new type service may be replaced with a specific service type indication, such as a holographic service, that is, the cause carried by the holographic service is: initiating a holographic service or receiving a holographic service.

The terminal respectively sends a connection establishment request (or a connection recovery request) to an access network node which needs to be accessed, and the cause is a new service type (such as holographic service, which can be further subdivided into initiation or reception), or a sub-service flow type of the new service type. The corresponding access network nodes respectively respond to the connection establishment of the terminal, if one or more access network nodes refuse the access of the terminal, the terminal can initiate a request to other alternative access network nodes of the same type, or a new access reason is introduced to be an access reason of the quality-reduced transmission of the new service type or the sub-service flow type of the new service type, and the terminal re-initiates an access process based on the new reason.

The terminal sends a connection establishment request (or a connection recovery request) to the primary access network node, and the cause is a new service type (such as a holographic service, which can be further subdivided into initiation or reception). The main access network node initiates a negotiation process to other access network nodes providing new service, and determines other access network nodes serving the terminal at the same time; or the main access network node initiates a notification message to other access network nodes providing new service (in this way, other access network nodes have previously determined to perform new service transmission together with the main access network node).

The following is an example.

The base station of the following embodiments refers to: a base station and an access network entity containing base station functions such as cell management, RRC, RRM (Radio resource management), Radio resource configuration and scheduling.

Example 1:

in this example, the terminal accesses a single cell.

Fig. 3 is a schematic diagram of a terminal access implementation flow in embodiment 1, as shown in the figure, the following steps may be performed:

step 301: admission (AC) parameters for a new traffic type (e.g., HTC) are broadcast.

The network side (including the core network and the access network) determines the admission capacity of the cell for the new service, and the base station carries the admission control parameters for the new service (such as HTC) in the cell system message.

Step 302: the terminal receives the system message (broadcast).

Step 303: and (4) receiving judgment and determining that the cell can be accessed.

And the terminal reads the system information of the cell, carries out admission control judgment according to the admission control parameters and determines whether the connection with the cell can be established.

Step 304: a connection establishment (recovery) request is initiated.

The terminal sends a connection establishment request (for an idle terminal) or a connection recovery request (for an inactive terminal) to the base station, wherein the carried reason corresponds to a new service (such as an HTC) indication, and the establishment reason can be further divided into: terminal initiated, or terminal received, or bi-directional.

Step 305: the core network accepts the process/new service parameter interaction.

A connection establishment process (NAS (Non Access Stratum) process) in which the terminal accesses the core network is performed between the base station and the core network, and a novel service parameter and sub-service stream type interaction may be performed between the core network and the base station, which is optional in this step.

Step 306: and determining the sub-service flow type corresponding to the accessed novel service, and configuring different wave beams/TPR/logical channel parameters for different sub-service flows.

The base station splits the sub-service stream type of the novel service, and configures Transmission parameters for the sub-service streams respectively, specifically beam parameters corresponding to the sub-service stream type, such as SSB (Synchronization Signal block and PBCH block)/CSI-RS (CSI Reference Signal; CSI: Channel State Information, Channel State Information), TCI (Transmission Configuration indication, Transmission Configuration Indicator) parameters associated with downlink Transmission, DMRS (demodulation Reference Signal) associated with uplink Transmission, TCI parameters, and the like; TRP (Transmission and Reception Point) parameter; logical channel parameters such as logical channel priority, transmission scheduling parameter limits, transmission resource limits, etc.

Step 307: and the terminal receives the configuration of the base station for the novel service.

Step 308: based on the configuration of the new type of traffic sub-traffic flow, information traffic data is transceived on different beams/TPR/logical channels.

And the terminal receives the configuration parameters of the base station aiming at the novel service, and transmits the novel service based on the configuration parameters.

Example 2:

in this example, the terminal accesses a plurality of cells (CA mode) under a single base station.

In embodiment 2, the terminal establishes RRC connection with only one cell (primary cell), so that the access parameter is controlled by the primary cell, and after the terminal accesses the primary cell, the base station configures a plurality of secondary cells for the terminal according to the characteristics of the new service of the terminal, so as to be used for transmitting a plurality of sub-service stream types, which is referred to as cell 1 in the specific example.

Fig. 4 is a schematic view of a terminal access implementation flow in embodiment 2, as shown in the figure, the following may be implemented:

step 401: cell 1 broadcasts an Admission (AC) parameter for the new traffic type, such as HTC.

Step 402: the terminal receives the system message (broadcast).

Step 403: and (4) receiving judgment and determining that the cell 1 can be accessed.

Step 404: a connection setup (recovery) request is initiated to cell 1.

Step 405: the core network accepts the process/new service parameter interaction.

Step 406: and determining the sub-service flow type corresponding to the accessed novel service, and configuring different cells for different sub-service flows for transmission.

Step 407: the terminal receives the new type service and the configuration of a plurality of cells.

Step 408: and based on the configuration, the sub-service flows of the novel service are transmitted and received on different cells.

The specific process is similar to that in embodiment 1, except that in step 401, the admission parameter is broadcast by one cell, in steps 407 and 408, the base station allocates multiple cells to the terminal, and different sub-service flows (mapped to different RBs (Radio Bearer)) are transmitted on different cells.

Example 3:

in this example, the terminal accesses multiple cells under a single base station (each cell establishes an independent RRC connection).

Fig. 5 is a schematic view of a terminal access implementation flow in embodiment 3, as shown in the figure, the following may be implemented:

step 501: admission (AC) parameters for a new traffic type (e.g., HTC) are broadcast.

The network side (including the core network and the access network) determines the admission capacity of each cell for the new service, and the base station carries admission control parameters for the new service (such as HTC) in the cell system message. The admission control parameters for each cell may be for a new type of service or, a new service sub-service flow type.

The terminal respectively sends a connection establishment request (for an idle terminal) or a connection recovery request (for an inactive terminal) to each cell needing to be accessed by the base station, wherein the carried reason corresponds to a novel service (such as HTC) indication or a novel service sub-service flow type indication.

Step 505: the core network accepts the process/new service parameter interaction.

The connection establishment process (NAS process) of the terminal accessing the core network is carried out between the base station and the core network, and novel service parameter and sub-service flow type interaction can be carried out between the core network and the base station.

2) the cell set supporting the new service is selected by the base station in embodiment 2 and selected by the terminal in embodiment 3;

3) in embodiment 2, if some cells cannot provide service for the terminal, other cells are reconfigured by the base station except the primary cell; in embodiment 3, if some cells cannot provide service for the terminal, the terminal needs to initiate a cell access procedure to another selected cell.

After determining a plurality of base stations participating in new service transmission, the base station sends configuration information to the terminal, adds a plurality of base stations and cells under the base stations for the terminal, and configures parameters of cell transmission of different sub-service flows under different base stations and base stations. And the terminal performs sub-service flow data transmission based on the configuration.

If part of auxiliary base stations providing the novel service for the terminal can not continue to provide the service for the terminal, the main base station additionally selects a base station capable of providing the service for the terminal, and the base station is configured and added to the terminal.

Example 5:

in this example, the terminal accesses multiple base stations (each base station establishing an independent RRC connection).

Fig. 7 is a schematic diagram of a terminal access implementation flow in embodiment 5, as shown in the figure, the following may be implemented:

In embodiment 5, a terminal receives system messages of cells under multiple base stations, determines admission parameters of multiple cells, makes admission decisions, and sends an access request message to each cell that needs to be accessed.

Each base station receiving the access request sent by the terminal sends access information to the terminal and sends transmission configuration for the terminal according to the sub-service flow type of the new service type supported by each base station.

The interaction of the novel service transmission can be carried out between the base stations, and how to cooperatively send different sub-service flow types of the novel service is determined between the base stations, and the interaction between the base stations can be a negotiation process of two-step handshaking or a notification process of one-step handshaking.

And the terminal performs different sub-service flow type data transmission with different base stations based on the configuration of different base stations.

If some base stations providing the new service for the terminal cannot continue to provide the service for the terminal, the terminal needs to monitor system messages of other base stations and try to initiate access to other base stations.
