Description

ACCESS CONTROL PARAMETER ADAPTATION BASED ON TRAFFIC CHARACTERISTIC

[0001] The present disclosure relates to access control parameter adaptation based on traffic characteristic.

[0002] 3rd Generation Partnership Project (3GPP) New Radio (NR) targets a single technical framework addressing all usage scenarios, requirements and deployment scenarios including enhanced Mobile BroadBand (eMBB), massive Machine Type Communications (mMTC), Ultra-Reliable and Low Latency Communications (URLLC), etc. The NR shall be inherently forward compatible. Further, the NR should be able to use any spectrum band ranging at least up to 100 GHz that may be made available for wireless communications even in a more distant future.

[0003] 6G is the successor to 5G cellular technology. 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. The 6G technology market is expected to facilitate large improvements in the areas of imaging, presence technology and location awareness. Working in conjunction with Artificial Intelligence (AI), the 6G computational infrastructure will be able to identify the best place for computing to occur. This includes decisions about data storage, processing and sharing.

[0004] In an aspect, a method is provided. The method comprises receiving multiple sets of access control parameters from a network. Each set of access control parameters is associated with a range of traffic characteristics. The method comprises determining a traffic characteristic, determining a set of access control parameters based on a traffic category and the traffic characteristic, and applying the set of access control parameters for the connection establishment.

[0005] In another aspect, an apparatus for implementing the above method is provided.

[0022] Technical features that are separately described in one drawing in the present disclosure may be implemented separately or simultaneously.

[0023] Although not limited thereto, various descriptions, functions, procedures, suggestions, methods and / or operational flowcharts of the present disclosure disclosed herein can be applied to various fields requiring wireless communication and / or connection (e.g., 5G) between devices.

[0024] Hereinafter, the present disclosure will be described in more detail with reference to drawings. The same reference numerals in the following drawings and / or descriptions may refer to the same and / or corresponding hardware blocks, software blocks, and / or functional blocks unless otherwise indicated.

[0025] FIG. 1 shows an example of a communication system to which implementations of the present disclosure are applied.

[0026] The 5G usage scenarios shown in FIG. 1 are only exemplary, and the technical features of the present disclosure can be applied to other 5G usage scenarios which are not shown in FIG. 1.

[0027] Three main requirement categories for 5G include (1) a category of enhanced Mobile BroadBand (eMBB), (2) a category of massive Machine Type Communication (mMTC), and (3) a category of Ultra-Reliable and Low Latency Communications (URLLC).

[0028] Referring to FIG. 1, the communication system 1 includes wireless devices 100a to 100f, Base Stations (BSs) 200, and a network 300. Although FIG. 1 illustrates a 5G network as an example of the network of the communication system 1, the implementations of the present disclosure are not limited to the 5G system, and can be applied to the future communication system beyond the 5G system.

[0029] The BSs 200 and the network 300 may be implemented as wireless devices and a specific wireless device may operate as a BS / network node with respect to other wireless devices.

[0030] The wireless devices 100a to 100f represent devices performing communication using Radio Access Technology (RAT) (e.g., 5G NR or LTE) and may be referred to as communication / radio / 5G devices. The wireless devices 100a to 100f may include, without being limited to, a robot 100a, vehicles 100b-1 and 100b-2, an eXtended Reality (XR) device 100c, a hand-held device 100d, a home appliance 100e, an Internet-of-Things (IoT) device 100f, and an Artificial Intelligence (AI) device / server 400. For example, the vehicles may include a vehicle having a wireless communication function, an autonomous driving vehicle, and a vehicle capable of performing communication between vehicles. The vehicles may include an Unmanned Aerial Vehicle (UAV) (e.g., a drone). The XR device may include an Augmented Reality (AR) / Virtual Reality (VR) / Mixed Reality (MR) device and may be implemented in the form of a Head-Mounted Device (HMD), a Head-Up Display (HUD) mounted in a vehicle, a television, a smartphone, a computer, a wearable device, a home appliance device, a digital signage, a vehicle, a robot, etc. The hand-held device may include a smartphone, a smartpad, a wearable device (e.g., a smartwatch or a smartglasses), and a computer (e.g., a notebook). The home appliance may include a TV, a refrigerator, and a washing machine. The IoT device may include a sensor and a smartmeter.

[0031] In the present disclosure, the wireless devices 100a to 100f may be called User Equipments (UEs). A UE may include, for example, a cellular phone, a smartphone, a laptop computer, a digital broadcast terminal, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a navigation system, a slate Personal Computer (PC), a tablet PC, an ultrabook, a vehicle, a vehicle having an autonomous traveling function, a connected car, an UAV, an AI module, a robot, an AR device, a VR device, an MR device, a hologram device, a public safety device, an MTC device, an IoT device, a medical device, a FinTech device (or a financial device), a security device, a weather / environment device, a device related to a 5G service, or a device related to a fourth industrial revolution field.

[0032] The wireless devices 100a to 100f may be connected to the network 300 via the BSs 200. An AI technology may be applied to the wireless devices 100a to 100f and the wireless devices 100a to 100f may be connected to the AI server 400 via the network 300. The network 300 may be configured using a 3G network, a 4G (e.g., LTE) network, a 5G (e.g., NR) network, and a beyond-5G network. Although the wireless devices 100a to 100f may communicate with each other through the BSs 200 / network 300, the wireless devices 100a to 100f may perform direct communication (e.g., sidelink communication) with each other without passing through the BSs 200 / network 300. For example, the vehicles 100b-1 and 100b-2 may perform direct communication (e.g., Vehicle-to-Vehicle (V2V) / Vehicle-to-everything (V2X) communication). The IoT device (e.g., a sensor) may perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0033] Wireless communication / connections 150a, 150b and 150c may be established between the wireless devices 100a to 100f and / or between wireless device 100a to 100f and BS 200 and / or between BSs 200. Herein, the wireless communication / connections may be established through various RATs (e.g., 5G NR) such as uplink / downlink communication 150a, sidelink communication (or Device-to-Device (D2D) communication) 150b, inter-base station communication 150c (e.g., relay, Integrated Access and Backhaul (IAB)), etc. The wireless devices 100a to 100f and the BSs 200 / the wireless devices 100a to 100f may transmit / receive radio signals to / from each other through the wireless communication / connections 150a, 150b and 150c. For example, the wireless communication / connections 150a, 150b and 150c may transmit / receive signals through various physical channels. To this end, at least a part of various configuration information configuring processes, various signal processing processes (e.g., channel encoding / decoding, modulation / demodulation, and resource mapping / de-mapping), and resource allocating processes, for transmitting / receiving radio signals, may be performed based on the various proposals of the present disclosure.

[0034] NR supports multiples numerologies (and / or multiple Sub-Carrier Spacings (SCS)) to support various 5G services. For example, if SCS is 15 kHz, wide area can be supported in traditional cellular bands, and if SCS is 30 kHz / 60 kHz, dense-urban, lower latency, and wider carrier bandwidth can be supported. If SCS is 60 kHz or higher, bandwidths greater than 24.25 GHz can be supported to overcome phase noise.

[0035] The NR frequency band may be defined as two types of frequency range, i.e., Frequency Range 1 (FR1) and Frequency Range 2 (FR2). The numerical value of the frequency range may be changed. For example, the frequency ranges of the two types (FR1 and FR2) may be as shown in Table 1 below. For ease of explanation, in the frequency ranges used in the NR system, FR1 may mean "sub 6 GHz range", FR2 may mean "above 6 GHz range," and may be referred to as millimeter Wave (mmW).

[0036] Frequency Range designationCorresponding frequency rangeSubcarrier SpacingFR1450MHz - 6000MHz15, 30, 60kHzFR224250MHz - 52600MHz60, 120, 240kHz

[0037] As mentioned above, the numerical value of the frequency range of the NR system may be changed. For example, FR1 may include a frequency band of 410MHz to 7125MHz as shown in Table 2 below. That is, FR1 may include a frequency band of 6GHz (or 5850, 5900, 5925 MHz, etc.) or more. For example, a frequency band of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or more included in FR1 may include an unlicensed band. Unlicensed bands may be used for a variety of purposes, for example for communication for vehicles (e.g., autonomous driving).

For example, NB-IoT technology may be an example of Low Power Wide Area Network (LPWAN) technology, may be implemented in specifications such as LTE Cat NB1 and / or LTE Cat NB2, and may not be limited to the above-mentioned names. Additionally and / or alternatively, the radio communication technologies implemented in the wireless devices in the present disclosure may communicate based on LTE-M technology.

[0063] A UE 100 includes a processor 102, a memory 104, a transceiver 106, one or more antennas 108, a power management module 141, a battery 142, a display 143, a keypad 144, a Subscriber Identification Module (SIM) card 145, a speaker 146, and a microphone 147.

[0064] The processor 102 may be adapted to implement the descriptions, functions, procedures, suggestions, methods and / or operational flowcharts disclosed in the present disclosure.

[0071] FIGS. 4 and 5 show an example of protocol stacks in a 3GPP based wireless communication system to which implementations of the present disclosure are applied.

[0072] In particular, FIG. 4 illustrates an example of a radio interface user plane protocol stack between a UE and a BS and FIG. 5 illustrates an example of a radio interface control plane protocol stack between a UE and a BS. The control plane refers to a path through which control messages used to manage call by a UE and a network are transported. The user plane refers to a path through which data generated in an application layer, for example, voice data or Internet packet data are transported. Referring to FIG. 4, the user plane protocol stack may be divided into Layer 1 (i.e., a PHY layer) and Layer 2. Referring to FIG. 5, the control plane protocol stack may be divided into Layer 1 (i.e., a PHY layer), Layer 2, Layer 3 (e.g., an RRC layer), and a Non-Access Stratum (NAS) layer. Layer 1, Layer 2 and Layer 3 are referred to as an Access Stratum (AS).

[0073] In the 3GPP LTE system, the Layer 2 is split into the following sublayers: MAC, RLC, and PDCP. In the 3GPP NR system, the Layer 2 is split into the following sublayers: MAC, RLC, PDCP and SDAP. The PHY layer offers to the MAC sublayer transport channels, the MAC sublayer offers to the RLC sublayer logical channels, the RLC sublayer offers to the PDCP sublayer RLC channels, the PDCP sublayer offers to the SDAP sublayer radio bearers. The SDAP sublayer offers to 5G core network Quality of Service (QoS) flows.

[0074] In the 3GPP NR system, the main services and functions of the MAC sublayer include: mapping between logical channels and transport channels; multiplexing / de-multiplexing of MAC SDUs belonging to one or different logical channels into / from Transport Blocks (TB) delivered to / from the physical layer on transport channels; scheduling information reporting; error correction through Hybrid Automatic Repeat reQuest (HARQ) (one HARQ entity per cell in case of Carrier Aggregation (CA)); priority handling between UEs by means of dynamic scheduling; priority handling between logical channels of one UE by means of logical channel prioritization; padding. A single MAC entity may support multiple numerologies, transmission timings and cells. Mapping restrictions in logical channel prioritization control which numerology(ies), cell(s), and transmission timing(s) a logical channel can use.

[0075] Different kinds of data transfer services are offered by MAC. To accommodate different kinds of data transfer services, multiple types of logical channels are defined, i.e., each supporting transfer of a particular type of information. Each logical channel type is defined by what type of information is transferred. Logical channels are classified into two groups: control channels and traffic channels. Control channels are used for the transfer of control plane information only, and traffic channels are used for the transfer of user plane information only. Broadcast Control Channel (BCCH) is a downlink logical channel for broadcasting system control information, Paging Control Channel (PCCH) is a downlink logical channel that transfers paging information, system information change notifications and indications of ongoing Public Warning Service (PWS) broadcasts, Common Control Channel (CCCH) is a logical channel for transmitting control information between UEs and network and used for UEs having no RRC connection with the network, and Dedicated Control Channel (DCCH) is a point-to-point bi-directional logical channel that transmits dedicated control information between a UE and the network and used by UEs having an RRC connection. Dedicated Traffic Channel (DTCH) is a point-to-point logical channel, dedicated to one UE, for the transfer of user information. A DTCH can exist in both uplink and downlink. In downlink, the following connections between logical channels and transport channels exist: BCCH can be mapped to Broadcast Channel (BCH); BCCH can be mapped to Downlink Shared Channel (DL-SCH); PCCH can be mapped to Paging Channel (PCH); CCCH can be mapped to DL-SCH; DCCH can be mapped to DL-SCH; and DTCH can be mapped to DL-SCH. In uplink, the following connections between logical channels and transport channels exist: CCCH can be mapped to Uplink Shared Channel (UL-SCH); DCCH can be mapped to UL-SCH; and DTCH can be mapped to UL-SCH.

[0076] The RLC sublayer supports three transmission modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). The RLC configuration is per logical channel with no dependency on numerologies and / or transmission durations. In the 3GPP NR system, the main services and functions of the RLC sublayer depend on the transmission mode and include: transfer of upper layer PDUs; sequence numbering independent of the one in PDCP (UM and AM); error correction through ARQ (AM only); segmentation (AM and UM) and re-segmentation (AM only) of RLC SDUs; reassembly of SDU (AM and UM); duplicate detection (AM only); RLC SDU discard (AM and UM); RLC re-establishment; protocol error detection (AM only).

[0077] In the 3GPP NR system, the main services and functions of the PDCP sublayer for the user plane include: sequence numbering; header compression and decompression using Robust Header Compression (ROHC); transfer of user data; reordering and duplicate detection; in-order delivery; PDCP PDU routing (in case of split bearers); retransmission of PDCP SDUs; ciphering, deciphering and integrity protection; PDCP SDU discard; PDCP re-establishment and data recovery for RLC AM; PDCP status reporting for RLC AM; duplication of PDCP PDUs and duplicate discard indication to lower layers. The main services and functions of the PDCP sublayer for the control plane include: sequence numbering; ciphering, deciphering and integrity protection; transfer of control plane data; reordering and duplicate detection; in-order delivery; duplication of PDCP PDUs and duplicate discard indication to lower layers.

[0078] In the 3GPP NR system, the main services and functions of SDAP include: mapping between a QoS flow and a data radio bearer; marking QoS Flow ID (QFI) in both DL and UL packets. A single protocol entity of SDAP is configured for each individual PDU session.

[0079] In the 3GPP NR system, the main services and functions of the RRC sublayer include: broadcast of system information related to AS and NAS; paging initiated by 5G Core network (5GC) or Next-Generation Radio Access Network (NG-RAN); establishment, maintenance and release of an RRC connection between the UE and NG-RAN; security functions including key management; establishment, configuration, maintenance and release of Signaling Radio Bearers (SRBs) and Data Radio Bearers (DRBs); mobility functions (including: handover and context transfer, UE cell selection and reselection and control of cell selection and reselection, inter-RAT mobility); QoS management functions; UE measurement reporting and control of the reporting; detection of and recovery from radio link failure; NAS message transfer to / from NAS from / to UE.

[0080] FIG. 6 shows a frame structure in a 3GPP based wireless communication system to which implementations of the present disclosure are applied.

[0081] The frame structure shown in FIG. 6 is purely exemplary and the number of subframes, the number of slots, and / or the number of symbols in a frame may be variously changed. In the 3GPP based wireless communication system, OFDM numerologies (e.g., SCS, Transmission Time Interval (TTI) duration) may be differently configured between a plurality of cells aggregated for one UE. For example, if a UE is configured with different SCSs for cells aggregated for the cell, an (absolute time) duration of a time resource (e.g., a subframe, a slot, or a TTI) including the same number of symbols may be different among the aggregated cells. Herein, symbols may include OFDM symbols (or Cyclic Prefix (CP)-OFDM symbols), SC-FDMA symbols (or Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbols).

[0082] Referring to FIG. 6, downlink and uplink transmissions are organized into frames. Each frame has Tf= 10ms duration. Each frame is divided into two half-frames, where each of the half-frames has 5ms duration. Each half-frame consists of 5 subframes, where the duration Tsfper subframe is 1ms. Each subframe is divided into slots and the number of slots in a subframe depends on a subcarrier spacing. Each slot includes 14 or 12 OFDM symbols based on a CP. In a normal CP, each slot includes 14 OFDM symbols and, in an extended CP, each slot includes 12 OFDM symbols. The numerology is based on exponentially scalable subcarrier spacing Δf = 2u*15 kHz.

[0083] Table 3 shows the number of OFDM symbols per slot Nslotsymb, the number of slots per frameNframe,uslot, and the number of slots per subframe Nsubframe,uslotfor the normal CP, according to the subcarrier spacing Δf = 2u*15 kHz.

[0085] Table 4 shows the number of OFDM symbols per slot Nslotsymb, the number of slots per frameNframe,uslot, and the number of slots per subframe Nsubframe,uslotfor the extended CP, according to the subcarrier spacing Δf = 2u*15 kHz.

[0086] uNslotsymbNframe,uslotNsubframe,uslot212404

[0087] A slot includes plural symbols (e.g., 14 or 12 symbols) in the time domain. For each numerology (e.g., subcarrier spacing) and carrier, a resource grid ofNsize,ugrid,x*NRBscsubcarriers andNsubframe,usymbOFDM symbols is defined, starting at Common Resource Block (CRB)Nstart,ugridindicated by higher-layer signaling (e.g., RRC signaling), whereNsize,ugrid,xis the number of Resource Blocks (RBs) in the resource grid and the subscript x is DL for downlink and UL for uplink.NRBscis the number of subcarriers per RB. In the 3GPP based wireless communication system,NRBscis 12 generally. There is one resource grid for a given antenna portp, subcarrier spacing configurationu, and transmission direction (DL or UL). The carrier bandwidthNsize,ugridfor subcarrier spacing configurationuis given by the higher-layer parameter (e.g., RRC parameter). Each element in the resource grid for the antenna portpand the subcarrier spacing configurationuis referred to as a Resource Element (RE) and one complex symbol may be mapped to each RE. Each RE in the resource grid is uniquely identified by an indexkin the frequency domain and an indexlrepresenting a symbol location relative to a reference point in the time domain. In the 3GPP based wireless communication system, an RB is defined by 12 consecutive subcarriers in the frequency domain.

[0088] In the 3GPP NR system, RBs are classified into CRBs and Physical Resource Blocks (PRBs). CRBs are numbered from 0 and upwards in the frequency domain for subcarrier spacing configurationu. The center of subcarrier 0 of CRB 0 for subcarrier spacing configurationucoincides with 'point A' which serves as a common reference point for resource block grids. In the 3GPP NR system, PRBs are defined within a BandWidth Part (BWP) and numbered from 0 toNsizeBWP,i-1, where i is the number of the bandwidth part. The relation between the physical resource block nPRBin the bandwidth part i and the common resource block nCRBis as follows: nPRB= nCRB+NsizeBWP,i, whereNsizeBWP,iis the common resource block where bandwidth part starts relative to CRB 0. The BWP includes a plurality of consecutive RBs. A carrier may include a maximum of N (e.g., 5) BWPs. A UE may be configured with one or more BWPs on a given component carrier. Only one BWP among BWPs configured to the UE can active at a time. The active BWP defines the UE's operating bandwidth within the cell's operating bandwidth.

[0089] In the present disclosure, the term "cell" may refer to a geographic area to which one or more nodes provide a communication system, or refer to radio resources. A "cell" as a geographic area may be understood as coverage within which a node can provide service using a carrier and a "cell" as radio resources (e.g., time-frequency resources) is associated with bandwidth which is a frequency range configured by the carrier. The "cell" associated with the radio resources is defined by a combination of downlink resources and uplink resources, for example, a combination of a DL Component Carrier (CC) and a UL CC. The cell may be configured by downlink resources only, or may be configured by downlink resources and uplink resources. Since DL coverage, which is a range within which the node is capable of transmitting a valid signal, and UL coverage, which is a range within which the node is capable of receiving the valid signal from the UE, depends upon a carrier carrying the signal, the coverage of the node may be associated with coverage of the "cell" of radio resources used by the node. Accordingly, the term "cell" may be used to represent service coverage of the node sometimes, radio resources at other times, or a range that signals using the radio resources can reach with valid strength at other times.

[0090] In CA, two or more CCs are aggregated. A UE may simultaneously receive or transmit on one or multiple CCs depending on its capabilities. CA is supported for both contiguous and non-contiguous CCs. When CA is configured, the UE only has one RRC connection with the network. At RRC connection establishment / re-establishment / handover, one serving cell provides the NAS mobility information, and at RRC connection re-establishment / handover, one serving cell provides the security input. This cell is referred to as the Primary Cell (PCell). The PCell is a cell, operating on the primary frequency, in which the UE either performs the initial connection establishment procedure or initiates the connection re-establishment procedure. Depending on UE capabilities, Secondary Cells (SCells) can be configured to form together with the PCell a set of serving cells. An SCell is a cell providing additional radio resources on top of Special Cell (SpCell). The configured set of serving cells for a UE therefore always consists of one PCell and one or more SCells. For Dual Connectivity (DC) operation, the term SpCell refers to the PCell of the Master Cell Group (MCG) or the Primary SCell (PSCell) of the Secondary Cell Group (SCG). An SpCell supports Physical Uplink Control Channel (PUCCH) transmission and contention-based random access, and is always activated. The MCG is a group of serving cells associated with a master node, comprised of the SpCell (PCell) and optionally one or more SCells. The SCG is the subset of serving cells associated with a secondary node, comprised of the PSCell and zero or more SCells, for a UE configured with DC. For a UE in RRC_CONNECTED not configured with CA / DC, there is only one serving cell comprised of the PCell. For a UE in RRC_CONNECTED configured with CA / DC, the term "serving cells" is used to denote the set of cells comprised of the SpCell(s) and all SCells. In DC, two MAC entities are configured in a UE: one for the MCG and one for the SCG.

[0091] FIG. 7 shows a data flow example in the 3GPP NR system to which implementations of the present disclosure are applied.

[0092] Referring to FIG. 7, "RB" denotes a radio bearer, and "H" denotes a header. Radio bearers are categorized into two groups: DRBs for user plane data and SRBs for control plane data. The MAC PDU is transmitted / received using radio resources through the PHY layer to / from an external device. The MAC PDU arrives to the PHY layer in the form of a transport block.

[0093] In the PHY layer, the uplink transport channels UL-SCH and Random Access Channel (RACH) are mapped to their physical channels Physical Uplink Shared Channel (PUSCH) and Physical Random Access Channel (PRACH), respectively, and the downlink transport channels DL-SCH, BCH and PCH are mapped to Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH) and PDSCH, respectively. In the PHY layer, Uplink Control Information (UCI) is mapped to PUCCH, and Downlink Control Information (DCI) is mapped to Physical Downlink Control Channel (PDCCH). A MAC PDU related to UL-SCH is transmitted by a UE via a PUSCH based on an UL grant, and a MAC PDU related to DL-SCH is transmitted by a BS via a PDSCH based on a DL assignment.

[0094] One unified access control framework applies to all UE states (RRC_IDLE, RRC_INACTIVE and RRC_CONNECTED) for NR. NG-RAN broadcasts barring control information associated with Access Categories and Access Identities (in case of network sharing, the barring control information can be set individually for each Public Land Mobile Network (PLMN)). The UE determines whether an access attempt is authorized based on the barring information broadcast for the selected PLMN, and the selected Access Category and Access Identity(ies) for the access attempt:

[0095] - For NAS triggered requests, NAS determines the Access Category and Access Identity(ies);

[0096] - For AS triggered requests, RRC determines the Access Category while NAS determines the Access Identity(ies).

[0097] The gNB handles access attempts with establishment causes "emergency", "mps-PriorityAccess" and "mcs-PriorityAccess" (i.e., Emergency calls,Multimedia Priority Service (MPS), Mission Critical Services MCS) subscribers) with high priority and responds with RRC Reject to these access attempts only in extreme network load conditions that may threaten the gNB stability.

[0098] When the UE needs to access the 5GS, the UE first performs access control checks to determine if the access is allowed. Access control checks shall be performed for the access attempts defined by various events.

[0099] When the NAS detects one of the various events, the NAS needs to perform the mapping of the kind of request to one or more access identities and one access category and lower layers will perform access barring checks for that request based on the determined access identities and access category.

[0100] The NAS is aware of the various events through indications provided by upper layers or through determining the need to start 5GMM procedures through normal NAS behaviour, or both.

[0101] To determine the access identities and the access category for a request, the NAS checks the reason for access, types of service requested and profile of the UE including UE configurations, against a set of access identities and access categories, namely:

[0102] a) a set of standardized access identities;

[0103] b) a set of standardized access categories; and

[0104] c) a set of operator-defined access categories, if available.

[0105] In order to enable access barring checks for access attempts identified by lower layers in 5GMM-CONNECTED mode with RRC inactive indication, the UE provides the applicable access identities to lower layers.

[0106] When the UE needs to initiate an access attempt in one of the events, the UE shall determine one or more access identities from the set of standardized access identities, and one access category from the set of standardized access categories and operator-defined access categories, to be associated with that access attempt.

[0107] The set of the access identities applicable for the request is determined by the UE in the following way:

[0108] a) for each of the access identities 1, 2, 3, 11, 12, 13, 14 and 15 in Table 5 below, the UE shall check whether the access identity is applicable in the selected PLMN, if a new PLMN is selected, or otherwise if it is applicable in the RPLMN or equivalent PLMN; and

[0109] b) if none of the above access identities is applicable, then access identity 0 is applicable.

[0110] Table 5 shows an example of access identities.

[0114] The RRC layer may perform a unified access control procedure. The purpose of this procedure is to perform access barring check for an access attempt associated with a given Access Category and one or more Access Identities upon request from upper layers or the RRC layer.

[0115] After a PCell change in RRC_CONNECTED, the UE shall defer access barring checks until it has obtainedSIB1from the target cell.

[0193] T390 = (0.7+ 0.6*rand)*uac-BarringTime.

[0194] As mentioned above, the UE may perform access control upon request for RRC connection establishment. The access control may be based on access categories and access identities of traffic to be served. For example, for MO-data, corresponding access category 7 may be applied.

[0195] However, the access category does not consider detailed traffic requirements and / or characteristics for access control. For example, the access category may not be distinguished and / or differentiated based on at least one of expected traffic intensity, traffic arrival rate, delay budget, and / or traffic priorities that can be differentiated depending on traffic-generating applications. For example, the access category may not be distinguished and / or differentiated based on whether the traffic is generated from strong user interaction (e.g., foreground traffic case) or from less or no user interaction (e.g., background traffic case). As a result, the access control cannot be differentiated based on traffic requirements and / or characteristics.

[0196] According to implementations of the present disclosure, the UE may receive a configuration comprising multiple sets of access control parameters from the network. Each set of access control parameters may be associated with a specific range of traffic characteristics. The UE may be configured with a specific set of access control parameters that are applicable when no other set of access control parameters is selected based on characteristics of traffic to be served.

[0197] For example, the traffic characteristics to be considered for access control may include at least on of traffic volumes to be served (e.g., traffic intensity / traffic arrival rate), traffic delay budgets, traffic priorities, traffic sources (e.g., foreground / background), etc. The traffic characteristics to be considered for access control will be described below in detail.

[0198] Additionally and / or alternatively, the multiple sets of access control parameters may be related to multiple traffic categories.

[0199] According to implementations of the present disclosure, the UE may further receive access control adaptation parameters. The access control adaptation parameters may be associated with a specific traffic characteristic. For example, access control adaptation parameters may be provided for a first traffic source type and a second traffic source type. The access control adaptation parameters may be provided per traffic category. The access control adaptation parameters may be provided as common parameters applicable to all traffic categories, unless exceptional traffic categories are not signaled.

[0200] According to implementations of the present disclosure, the UE may receive an indication that requires connection establishment. For example, the UE may receive the indication from upper layer (e.g., NAS layer). For example, the UE may receive the indication from the network for Mobile Terminated (MT) connection via e.g., paging.

[0201] According to implementations of the present disclosure, the UE may determine the traffic characteristic and / or a traffic category (e.g., access category) to be served based on the received indication.

[0202] According to implementations of the present disclosure, the UE may check if the access to the cell for the connection establishment is allowed or not based on the access control parameters and / or the determined traffic characteristic. During the check, the UE may determine a set of access control parameters for the connection establishment based on the determined traffic characteristic. The set of access control parameters may include at least one of barring factor, barring time and / or access identities. For example, the UE may determine a barring factor to apply, a barring time to apply, and / or access identities to be allowed for access.

[0203] According to implementations of the present disclosure, for determination of a set of access control parameters, the UE may determine / derive / select a specific set of access control parameters based on the received multiple sets of access control parameters.

[0204] For example, the UE may use a certain set of access control parameters from the multiple sets of access control parameters as a reference set, and determine the set of access control parameters based on the reference set and the determined traffic characteristic.

[0205] For example, the UE may use a first certain set of access control parameters from the multiple sets of access control parameters as a reference set, a second certain set of access control parameters associated with the traffic characteristic including the determined traffic characteristic as an adjustment set. The UE may construct a modified set of access control parameters based on the reference set and the adjustment set and apply the modified set of access control parameters for the access control.

[0206] For example, the UE may select a specific set of access control parameters among the received multiple sets of access control parameters. The selected set of access control parameters may be associated with a specific traffic characteristic range including the determined traffic characteristic.

[0207] According to implementations of the present disclosure, the UE may apply the determined set of access control parameters for access control. For example, the UE may check the determined access identities. If the UE belongs to at least one determined access identity for which access is allowed, the UE may consider that the access is allowed. If the UE does not belong to at least one determined access identity for which access is allowed, the UE may draw a random number in the uniform distribution [0,1] and compare the random number with the determined access barring factor to determine whether the current access attempt is allowed. If the random number is smaller than the determined value, the UE may consider that the access is allowed, and otherwise the UE may consider that the access is not allowed. If the UE determines that the access to the cell is allowed, the UE may initiate a connection establishment procedure. If the UE determines that the access to the cell is not allowed, the UE may consider that the access to this cell is barred for the determined barring time.

[0208] According to implementations of the present disclosure, various traffic characteristics may be considered as follows.

[0209] (1) Traffic volumes based access control parameter determination

[0210] The traffic volume types to be considered for access control may be as follows:

[0211] - Type1: the observed and / or expected total size of traffic volumes to be served within a certain time period (e.g., traffic intensity); and / or

[0212] - Type2: the observed or expected average rate of data arrival

[0213] For any type, a set of access control parameters associated with a certain range of traffic volume type may be configured.

[0214] Direction of the traffic may be also considered for the traffic volume. For example, only UL traffic volume or DL traffic volume may be considered for the traffic volume based access control. Or, both UL traffic volume and DL traffic volume may be considered for the traffic volume based access control. The UE may be configured with the direction of traffic to be considered for the access control.

[0215] (2) Traffic delay budget based access control parameter determination

[0216] For at least one range of delay budgets, a set of access control parameters associated with the delay budget range may be configured. For example, for 'MO-data' traffic, different sets of access control parameters may be determined depending on the delay budget of the traffic to be served.

[0217] (3) Traffic priority based access control parameter determination

[0218] For at least one range of traffic priorities, a set of access control parameters associated with the traffic priority range may be configured. For example, for 'MO-data' traffic, different sets of access control parameters may be determined depending on the priority of the traffic to be served.

[0219] (4) Traffic source based access control parameter determination

[0220] The traffic source types may be one of foreground traffic and background traffic. The traffic source types may be further differentiated based on the level of user interaction / involvement related to generating the traffic to be served.

[0221] The UE may determine the set of access control parameters based on the determined traffic category and / or the determined traffic source type by using the multiple sets of access control parameters for multiple traffic categories and / or the access control adaptation parameters. For example, the UE may select a specific set of access control parameters among the received multiple sets of access control parameters based on the determined traffic category (e.g., access category). Then, the UE may apply the adaptation parameters, that are selected based on the determined traffic source type, to the selected set of access control parameters. For example, the UE may select a specific set of access control parameters that are configured for the determined traffic source type.

[0222] In case the common set of access control parameters are applied without adjustment for a specific traffic source type, the network may not signal the corresponding adaptation parameters.

[0223] Without loss of generality, there may be more than two traffic source types.

[0224] The following drawings are created to explain specific embodiments of the present disclosure.

The traffic volumes may include at least one of UL traffic volumes and / or DL traffic volumes.

[0252] For example, the traffic sources may include a foreground traffic and / or a background traffic. The traffic sources may be differentiated based on degree of user interaction and / or involvement related to traffic.

[0262] Furthermore, the method described above in FIG. 8 may be performed by a software code 105 stored in the memory 104 included in the first wireless device 100 shown in FIG. 2.

[0263] The technical features of the present disclosure may be embodied directly in hardware, in a software executed by a processor, or in a combination of the two. For example, a method performed by a wireless device in a wireless communication may be implemented in hardware, software, firmware, or any combination thereof. For example, a software may reside in RAM, flash memory, ROM, EPROM, EEPROM, registers, hard disk, a removable disk, a CD-ROM, or any other storage medium.

[0264] Some example of storage medium may be coupled to the processor such that the processor can read information from the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC. For other example, the processor and the storage medium may reside as discrete components.

Non-transitory computer-readable media may also include combinations of the above.

[0267] In addition, the method described herein may be realized at least in part by a computer-readable communication medium that carries or communicates code in the form of instructions or data structures and that can be accessed, read, and / or executed by a computer.

[0268] According to some implementations of the present disclosure, a non-transitory Computer-Readable Medium (CRM) stores instructions that, based on being executed by at least one processor, perform the method described in FIG. 8.

[0269] FIG. 9 shows an example of another method to which implementations of the present disclosure are applied.

[0270] In step S900, the method comprises transmitting multiple sets of access control parameters to a wireless device. Each set of access control parameters is associated with a range of traffic characteristics. A set of access control parameters is determined based on i) a traffic category, and ii) a traffic characteristic. The set of access control parameters is applied for connection establishment.

[0271] Furthermore, the method described above in FIG. 9 may be performed by a base station. The base station may be implemented by the second wireless device 200 shown in FIG. 2.

[0272] The base station comprises at least one transceiver, at least one processor, and at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, cause the base station to perform the method described in FIG. 9.

[0273] More specifically, the base station transmits multiple sets of access control parameters to a wireless device. Each set of access control parameters is associated with a range of traffic characteristics. A set of access control parameters is determined based on i) a traffic category, and ii) a traffic characteristic. The set of access control parameters is applied for connection establishment.

[0274] The following description relates to an example of traffic source based access control parameter determination.

[0275] For example, for access category #N, the network wants to configure different sets of access control parameters depending the traffic source types, as follows:

[0276] (1) Traffic source type1 (background)

[0277] - barringFactor = 0.25

[0278] - barringTime = 16 seconds

[0279] - AccessIdentity = 0000000

[0280] (2) Traffic source type2 (foreground)

[0281] - barringFactor = 0.5

[0282] - barringTime = 4 seconds

[0283] - AccessIdentity = 0000000

[0284] For this purpose, the network may configure two sets of access control parameters for access category #N as follows. One of the two sets may be applied to background traffic and the other may be applied to foreground traffic.

[0285] (1) Parameter set #1 (corresponding to Traffic source type1) for Access Category #N

[0286] - barringFactor = 0.25

[0287] - barringTime = 16 seconds

[0288] - AccessIdentity = 0000000

[0289] (2) Parameter set #2 (corresponding to Traffic source type2) for Access Category #N

[0290] - barringFactor = 0.5

[0291] - barringTime = 4 seconds

[0292] - AccessIdentity = 0000000

[0293] Then, if connection needs to be established for Access Category #N, the UE may select one of the two sets of access control parameters to apply for the access control.

[0294] Alternatively, the network may configure a common set of access control parameters for Access Category #7, and two sets of access control adaptation parameters for the Access Category #7 as follows.

[0295] (1) Common set of access control parameters for Access Category #7

[0296] - barringFactor = 0.5

[0297] - barringTime = 4 seconds

[0298] - AccessIdentity = 0000000

[0299] (2) Access control adaptation parameters for Traffic source type1 (background) for Access Category 7

[0300] - barringFactorScalingFactor= 0.5: this value is applied (as multiplication) to the corresponding value in common set of access control parameters for the Access Category #7

[0301] - barringTimeScalingFactor = 4: this value is applied (as multiplication) to the corresponding value in common set of access control parameters for the Access Category #7

[0302] (3) Access control adaptation parameters for Traffic source type2 (foreground) for Access Category #7

[0303] - barringFactorScalingFactor=1: this value is applied (as multiplication) to the corresponding value in common set of access control parameters for the Access Category #7

[0304] - barringTimeScalingFactor = 1: this value is applied (as multiplication) to the corresponding value in common set of access control parameters for the Access Category #7

[0305] Then, if connection needs to be established for Access Category #7, the UE may determine the set of access control parameters to apply for the access control by using the access control parameters that are derived by multiplying the traffic source type specific scaling factors to the corresponding parameters in the common set of access control parameters.

[0306] The present disclosure may have various advantageous effects.

[0307] For example, access control can be optimized such that fine grained different access control parameters are applied according to the traffic requirement.

[0308] For example, access control can be optimized such that differentiated access control parameters are applied depending on whether the traffic is a foreground traffic or a background traffic.

[0309] Advantageous effects which can be obtained through specific embodiments of the present disclosure are not limited to the advantageous effects listed above. For example, there may be a variety of technical effects that a person having ordinary skill in the related art can understand and / or derive from the present disclosure. Accordingly, the specific effects of the present disclosure are not limited to those explicitly described herein, but may include various effects that may be understood or derived from the technical features of the present disclosure.
