An example of a use case is illustrated. An embodiment of the device will be illustrated. Other embodiments of the device will be illustrated.

The following embodiments are merely examples. The specification may refer to embodiments of "an", "one", or "some" in multiple places, but this is not necessarily the case. It does not mean that each of these references is for the same embodiment, or that its features apply to only a single embodiment. It is also possible to combine a single feature of different embodiments to provide other embodiments. Further, the terms "comprising" (including, including) "and" including (including) "are understood as not limiting the described embodiments to consist solely of the mentioned features. It should, and such embodiments may also include features, structures, units, modules, etc. that are not specifically mentioned.

Embodiments include any user device, such as a user terminal, and any network element, relay node, server, node, corresponding component and / or any communication system or different communication system that supports the required functionality. Applicable to any combination. The communication system can be a wireless communication system or a communication system that uses both fixed and wireless networks. The specifications of the protocols, communication systems and devices used, such as servers and user terminals, are evolving rapidly, especially in wireless communications. Such developments may require additional changes to the embodiment. Therefore, all words and expressions must be construed in a broad sense and are intended to be exemplary rather than limiting embodiments.

In the following, different exemplary embodiments will be described using a long term evolution advanced (LTE Advanced, LTE-A) based wireless access architecture as an example of an access architecture to which the embodiments can be applied. However, the embodiments are not limited to such architectures. It will be apparent to those skilled in the art that by appropriately adjusting the parameters and procedures, the embodiments can be applied to other types of communication networks having suitable means. Some examples of other options as suitable systems are the same as 5G, Universal Mobile Communication Systems (UMTS) Wireless Access Networks (UTRAN or E-UTRAN), Long Term Evolution (LTE, E-UTRA). ), Wireless Local Area Network (WLAN or Wi-Fi®), Global Interoperability for Microwave Access (WiMAX), Bluetooth®, Personal Communications Services (PCS), ZigBee (Registered Trademarks), Broadband Code Division Multiplexing (WCDMA), Systems Using Ultra Wideband (UWB) Technology, Sensor Networks, Mobile Adhook Networks (MANET) and Internet Protocol Multimedia Subsystems (IMS) Or any combination thereof.

FIG. 1 is an example of a simplified system architecture that is all logical units and only shows some elements and functional entities that can have different implementations than those shown. I'm drawing. The connection shown in FIG. 1 is a logical connection, and the actual physical connection can be different. It will be apparent to those skilled in the art that the system typically also includes functions and structures other than those shown in FIG.

However, embodiments are not limited to the systems provided as an example, and one of ordinary skill in the art can apply the solution to other communication systems with the required characteristics. Another embodiment of a suitable communication system is the 5G concept. It is hypothesized that the wireless network architecture in 5G can be very similar to that of LTE-advanced. 5G is a multiple input-multiple output (MIMO) antenna, a macro site that works in conjunction with smaller stations and probably also uses various wireless technologies for better cabadage and enhanced data transfer speeds. It is likely to use far more base stations or nodes than LTE (the so-called small cell concept), including. The 5G is likely to consist of two or more radio access technologies (RACs), each optimized for a given use case and / or spectrum. 5G mobile communications is a wider range of use cases, including video streaming, augmented reality, different data sharing methods and various forms of machine-type applications including vehicle safety, different sensors and real-time control. And have related applications.

In future networks, network functionality is a network architecture concept that proposes to virtualize network node functionality into "building blocks" or entities that can be actively connected or linked together to provide services. It should be recognized that virtualization (NFV) is most likely to be used. A virtualized network function (VNF) can include one or more virtual machines that execute computer program code using standard or generic type servers instead of customized hardware. Cloud computing or data storage is available as well. In wireless communication, this can mean that node operations are performed, at least in part, on a server, host or node operatively coupled to a remote wireless head. It is similarly possible to distribute node operations among multiple servers, nodes or hosts. It should also be understood that the distribution of work between core network operations and base station operations may differ from that of LTE, or even nonexistent. Perhaps some other technological advances to be used are software-defined networking (SDN), big data and all-IP, which can change the way networks are built and managed.

Figure 1 shows E-UTRA, ITE, LTE-Advanced (LTE-A) or LTE / EPC (EPC = evolved packet core), where EPC has faster data transfer speeds and Internet protocol traffic. A part of the radio access network based on (which is an enhancement of packet switching technology to cope with the growth of E-UTRA is an LTE release 8 air interface (UTRA = UMTS terrestrial radio access, UMTS = universal mobile communication system). Some of the advantages that can be gained with LTE (or E-UTRA) are that plug-and-play devices and frequency division bidirectional (FDD) and time division bidirectional (TDD) can be used within the same platform. There is.

FIG. 1 shows user devices 100 and 102 configured to be wirelessly connected to (e) NodeB 108 providing the cell on one or more communication channels 104 and 106 in the cell. The physical link from the user device to (e) NodeB is called an uplink or reverse link, and the physical link from (e) NodeB to the user device is called a downlink or forward link.

The other two nodes (eNodeB), namely 114 and 116, are also provided, and they can have communication channels 118 and 120 for the eNodeB 108. Nodes can belong to the same operator's network or different operators' networks. It should be recognized that the number of nodes can vary as much as the number of networks. User devices communicating with nodes 114 and 116 are not shown for clarity. Nodes can have connections to other networks as well.

A NodeB or Advanced Evolved Node B (eNodeB, eNB) in LTE-Advanced is a computing device configured to control the wireless communication system resource to which it is attached. (E) NodeB may also be referred to as any other type of interfacing device, including base stations, access points or relay stations capable of operating in a wireless environment as well.

(E) NodeB includes or is coupled to a transmitter / receiver. (E) The NodeB transmitter / receiver provides a connection to the antenna that establishes a bidirectional wireless link to the user device. The antenna unit can include a plurality of antennas or antenna elements. (E) NodeB is further connected to the core network 110 (CN). Depending on the system, the other party on the CN side is the service gateway (S-GW, which routes and forwards user data packets), the connectivity of the user device (UE) to the external packet data network. It can be a packet data network gateway (P-GW), a mobile management entity (MME), or the like to provide.

Communication systems typically include two or more (e) NodeBs, in which case (e) NodeBs are similarly configured to communicate with each other over wired or wireless links designed for this purpose. be able to. These links can be used for signaling purposes.

The communication system can also communicate with the public switched telephone network or other networks such as the Internet 112. Communication networks can also support the use of cloud services. It should be recognized that (e) NodeB or its functionality can be implemented by using any node, host, server or access point that is a suitable entity for such use.

Communication systems can also include central control entities that provide the convenience of networks of different operators to work together, for example in spectral sharing.

A user device (also referred to as a UE, user device, user terminal, terminal device, etc.) exemplifies one of the devices to which resources on the air interface are allocated and allocated, and thus the user device is described herein. Any feature described therein can be implemented using a corresponding device such as a relay node. One embodiment of such a relay node is a layer 3 relay (self-backhoeing relay) heading to the base station.

User devices are typically mobile stations (mobile phones), smart phones, personal digital assistants (PDAs), handsets, devices that use wireless modems (such as alarms or measurement devices), laptops and / or touch screens. · Wireless mobile communication devices that operate with or without a Subscriber Identification Module (SIM), including non-limiting types of devices such as computers, tablets, game consoles, laptops and multimedia devices. Means a portable computing device that includes. It should be recognized that the user device can also be a nearly exclusive uplink dedicated device, an example of which is a camera or video camera that loads an image or video into the network. User devices also have the ability to operate in the Internet of Things (IoT) network, a scenario in which objects are provided with the ability to transfer data over a network without the need for person-to-person or person-to-computer interaction. It can also be a device that has. The user device can also be a device operating within a cyber-physical system (CPS), which is a system of cooperating computational elements that control a physical entity.

The user device (or, in some embodiments, a Layer 3 relay node or self-backhoeing node) is configured to perform one or more of the functionality of the user equipment. User devices can also be similarly referred to as subscriber units, mobile stations, remote terminals, access terminals, user terminals or user equipment (UEs), to name just a few.

In FIG. 1, the user device is drawn to include only two antennas for clarity. Of course, the number of receive and / or transmit antennas can vary depending on the current implementation.

Further, although the device is depicted as a single entity, different units, processors and / or memory units (not all shown in FIG. 1) can be implemented.

For those skilled in the art, the depicted system is only one example of a wireless access system, in which the system can actually include multiple (e) NodeBs and the user device in multiple wireless cells. It is clear that they are accessible and that the system can also include other devices such as physical layer relay nodes or other network elements. At least one of NodeB or eNodeB can be Home (e) NodeB. In addition, a plurality of different types of radio cells as well as a plurality of radio cells can be provided within the geographical area of the radio communication system. The radio cell can be a macro cell (or umbrella cell), which is a large cell, usually with a diameter of up to tens of kilometers, or a smaller cell, such as a micro, femto, or picto cell. (E) NodeB of FIG. 1 can provide these cells of any kind. Cellular wireless systems can be implemented as a multilayer network containing multiple types of cells. Typically, in a multilayer network, one node B provides one type of cell, and thus a plurality of (e) NodeBs are required to provide such a network structure.

The concept of "plug and play" (e) NodeB has been introduced to meet the need to improve the deployment and performance of communication systems. Typically, networks that can use "plug and play" (e) NodeB are Home (e) NodeB (H (e) nodeB) plus Home Node B gateways or HNB-GW (FIG. 1). Is not shown). An HNB gateway (HNB-GW) typically installed inside an operator's network can aggregate traffic from multiple HNBs back to one core network.

In the following, one embodiment of the connection configuration will be disclosed with reference to FIG. This embodiment can be implemented by a user device. The embodiment is suitable for adapting the operating mode of the user device to effectively support resource usage and support different services and / or applications. For example, the requirements for machine-based communications (MTCs) often deviate from the requirements for human-based communications (various types of MTCs enable the wireless Internet of Things (IoT)). Control operational state (and related common and dedicated system information) in the presence of multi-link, multi-layer, multi-RAT and / or various applications or services using the service information-based configurable state. A method is provided. In describing embodiments and examples, LTE-related terminology may be used for clarity. However, such terms should not be taken as limiting the embodiments or examples.

The embodiment starts at block 200.

In block 202, a connection request including service information is transmitted.

The connection request is transmitted to the network that the user device wants to use for communication to inform the network about the need for service of the user device. The information in the message can vary, but in principle it provides the information that the network needs for resource configuration. The service information can be a service identity (ID) and / or an application identity (ID). These identities are standardized, notified as part of random access or as a corresponding procedure (unicast or multicast), notified in the broadcast transmitted by the access node providing the cell, and negotiated between service providers. It is possible to do things like that. These identities can take the form of, for example, lists or tables. In 5G, it was proposed that cells advertise more actively available services. Therefore, the user device can request a service that provides the closest match to its capabilities and / or needs. The service information can also include the mobility status of the user device as well. The mobility status information can be based on location or tracking information (using, for example, Global Positioning System or range detection) and / or information obtained from, for example, speed sensors or radar.

The service information can also include markings of resources dedicated to this service. This is useful information in network slicing, where a machine-type communication device can indicate to a network which network slices are applicable to that device or service.

The connection request can include information about the user device capability, or it can carry a separate message containing this information. For example, the capabilities of smart phones can vary from model to model. The connection request can also include information about the user device's labor-saving configuration or labor-saving request. For example, certain services or applications can have dedicated labor saving settings or labor saving modes. The connection request can be transmitted after a random access procedure, etc., using the resources reserved or configured for the connection request.

At block 204, configuration information is received in response to a connection request, and a connection is established based on this configuration information.

In response to a connection request, the network sends confirmation or setup messages, etc., in which resources or configurations for this connection are announced. The user device establishes a connection to the network based on this information.

At block 206, at least one message is received indicating the reconfiguration or disconnection to the intermediate state based on the service information.

An intermediate state means a flexible operating state that is neither idle nor "full" active. In the intermediate state, the user device can perform operations adapted to the service or application in question. An operation that can be configured to be performed by a user device is the registration of the user device (the user device is typically registered with a unique identifier within its tracking area consisting of many cells. (Can be recognized), tracking and / or location, packet forwarding, camping, receiving system information, monitoring paging channels, authentication, contention-based uplink data transmission, and more.

An example of how a service or application affects operations performed in an intermediate state, or the inability to idle, is along a user device, such as a road, participating in an activity. It may be a moving vehicle that must collect certain information about itself and / or its environment, in which case the configuration associated with this user device is free by the access node. The service and / or application determines the operation to be performed in the intermediate state or prohibits the idle state. For example, a vehicle that uses some type of autonomous driving assistance may need to be able to communicate with the service control unit in a prescribed manner.

Mobility status can be considered when operations related to reconfiguration or disconnection are performed. Mobility status can distinguish between normal (ie, immobile, slow-moving, or infrequent cell changes) and mobile devices. Movable devices may have restrictions on intermediate states. In one embodiment, only these devices in the normal mobility state can be configured in the intermediate state. For another embodiment, only mobile devices whose speed is faster than the speed of a pedestrian can be configured into an intermediate state, for example as part of fleet management or some collision detection or automated vehicle driving. Other devices can be configured idle to save resources.

The embodiment ends at block 208. The embodiments are repeatable in many different ways, for example, the reconstruction can be repeated to change the state from an intermediate state to an idle or active state.

In the following, another embodiment of the connection configuration will be disclosed with reference to FIG. This embodiment can be implemented by an access node, server, host, or corresponding device. An access node, server or host can be a node that provides cellular coverage for general purpose wireless communication, or access that supports certain services such as vehicle-to-vehicle (V2V) communication or vehicle-mounted (V2X) communication. -It can also be a node. The embodiments are suitable for adapting the operating mode of the user device to support different services and / or applications effectively using resources. For example, the requirements for machine-based communications (MTCs) often deviate from the requirements for human-based communications (various types of MTCs enable the wireless Internet of Things (IoT)). Control operational state (and related common and dedicated system information) in the presence of multi-link, multi-layer, multi-RAT and / or various applications or services using the service information-based configurable state. A method is provided. In describing embodiments and examples, LTE-related terminology may be used for clarity. However, such terms should not be taken as limiting the embodiments or examples.

The embodiment starts at block 300.

At block 302, a connection request to the user device is received. The connection request includes service information.

The connection request is transmitted to the network that the user device wants to use for communication to inform the network about the need for service of the user device. The information in the message can vary, but in principle it provides the information that the network needs for resource configuration. The service information can be a service identity (ID) and / or an application identity (ID). These identities are standardized, notified as part of random access or as a corresponding procedure (unicast or multicast), notified in the broadcast transmitted by the access node providing the cell, and negotiated between service providers. It is possible to do things like that. These identities can take the form of, for example, lists or tables. The access node can advertise information about its service by unicast, multicast or broadcast. Therefore, the user device can request a service that provides the closest match to its capabilities and / or needs.

The service information can also include the mobility status of the user device as well. The mobility status information can be based on location or tracking information (using, for example, Global Positioning System or range detection) and / or information obtained from, for example, speed sensors or radar.

The service information can also include markings of resources dedicated to this service. This is useful information in network slicing, where a machine-type communication device can indicate to a network which network slices are applicable to that device or service.

The connection request can include information about the user device capability, or it can carry a separate message containing this information. For example, the capabilities of smart phones can vary from model to model. The connection request can also include information about the user device's labor-saving configuration or labor-saving request. For example, certain services or applications can have dedicated labor saving settings or labor saving modes. The connection request can be transmitted after a random access procedure or the like, using the resources reserved for the connection request.

At block 304, a connection configuration is implemented in response to the connection request.

The step of performing the connection configuration typically includes the step of transmitting a connection configuration response, confirmation or setup message, etc., where the resource or configuration for the connection is notified. The user device establishes a connection to the network based on this information.

At block 306, interruptions in data transmission associated with the configured connection are detected.

Detection can be based on an inactivity timer that counts the duration of dormancy. If this duration exceeds a predetermined threshold, a break is registered. End of data markers can also be used.

At block 308, in response to the interruption, either reconfiguration to the intermediate state or disconnection is performed based on the service information.

An intermediate state means a flexible operating state that is neither idle nor "full" active. In the intermediate state, the user device can perform operations adapted to the service or application in question. An operation that can be configured to be performed by a user device is the registration of the user device (the user device is typically registered with a unique identifier within its tracking area consisting of many cells. (Can be recognized), tracking and / or location, packet forwarding, camping, receiving system information, paging channel monitoring, authentication, contention-based uplink data transmission, and more.

For example, if the service is of a one-off nature, such as uploading or calling a video clip, you can disconnect. In this case, the user device can be put into an idle state or mode.

An example of how a service or application affects operations performed in an intermediate state, or the inability to idle, is along a user device, such as a road, participating in an activity. It may be a moving vehicle that must collect certain information about itself and / or its environment, in which case the configuration associated with this user device is free by the access node. The service and / or application determines the operation to be performed in the intermediate state or prohibits the idle state. For example, a vehicle that uses some type of autonomous driving assistance may need to be able to communicate with the service control unit in a prescribed manner.

Mobility status can be considered when operations related to reconfiguration or disconnection are performed. Mobility status can distinguish between normal (ie, immobile, slow-moving, or infrequent cell changes) and mobile devices. Movable devices may have restrictions on intermediate states. In one embodiment, only these devices in the normal mobility state can be configured in the intermediate state. For another embodiment, only mobile devices whose speed is faster than the speed of a pedestrian can be configured into an intermediate state, for example as part of fleet management or some collision detection or automated vehicle driving. Other devices can be configured idle to save resources.

As a message containing information about the availability of procedures for updating user device enrollment, capabilities, contextual information, security and / or credentials, paging information, location information, mobility status information and / or location information. , Reconstruction can be carried.

From the point of view of the access node, interrupting transmissions on a connection can be thought of as overloading functionality, i.e. creating multiple methods of the same name with different implementations. A call to an overloaded feature executes a specific implementation of this feature that is appropriate for the context of the call, allowing one feature call to perform different tasks depending on the context.

In one embodiment, the mobility management entity is notified about service information as part of a context setup procedure. Contexts can be used in authentication and / or accounting. A mobility management entity is an entity responsible for paging, authenticating, and / or authorizing a user device in idle mode. If the mobility management entity is aware of the service information, it can perform, for example, service-based or application-based authentication.

In another embodiment, the paging procedure can be initiated by a radio access network for system access based on service information.

The embodiment ends at block 310. The embodiments are repeatable in many different ways, for example, the reconstruction can be repeated to change the state from the intermediate state to the idle state. Another option is to change from an intermediate or idle state to an active / connected state when the user device transmits a new connection request.

In the following, a signal chart for illustration is shown with reference to FIG. LTE-related terms are used for clarity. However, such terms should not be taken as limiting the embodiments or examples.

In this embodiment, messages 1 (random access channel, RACH) and 2 (uplink grant) are for the random access process. By message 3 (Radio Resource Control, RRC), a connection request containing mobility management identity (MME_ID), user device identity (UE ID) and service information (service_ID) is sent from the user device to the access node (in this case). It is transmitted to eNB). The access node responds by transmitting a connection setup message (RRC conn.setup), and the user device responds to this message by transmitting a connection setup complete message (RRC conn.setup). The user device (UE) is active and has resources for data transmission. The access node then detects an interruption in data transmission. Depending on the service information, the access node chooses to either disconnect (7b) or reconfigure to intermediate state or mode (7a). From the point of view of the access node, interrupting transmissions on a connection can be thought of as a feature overloading, a feature that creates multiple methods of the same name with different implementations. A call to an overloaded feature executes a specific implementation of this feature that is appropriate for the context of the call, allowing one feature call to perform different tasks depending on the context. In other words, interruptions in transmission lead to either reconfiguration or disconnection. As an option, mobility management entities (MMEs) or similar functionality in radio access networks are communicated about service information as part of the context setup procedure (6).

In the following, some non-limiting cases are presented with reference to FIGS. 5a and 5b. LTE-related terms are used for clarity. However, such terms should not be taken as limiting the embodiments or examples. LTE-related terms are, for example, RRC (Radio Resource Control) and ECM (EPS Connection Management, where EPS stands for Evolved Packet System).

In FIG. 5a, the user device can be a machine-based communication (MTC) device. Mass-MTCs typically relate to mass deployments of low cost battery powered sensors, actuators, remote controlled and / or remote read supply and demand instruments. One example is an instrument read / report sensor with extended battery life requirements. In this case, there is no need for camping within the cell and therefore the device does not need to be in idle mode or state. This type of device only requires registration and can be put into a labor saving mode (one type of intermediate state), for example if it is not transmitting data to the service control unit. If the user device is an ultra-reliable machine-based communication (U-MTC) device, the user device, when in the intermediate state, camps on the cell, performs a tracking area procedure, and one or more. You can continuously monitor your paging channel. Ultra-reliable MTCs are very likely to be associated with providing a certain level of service. Ultra-reliable MTCs are also relevant for applications where delay is a decisive factor, such as remote control, industrial control or remote surgery. The state of the user device in these cases is a connected / active state or an intermediate state. Therefore, this example also depicts a case where idle mode is not allowed due to high speed system access requirements.

Another embodiment involves Extreme Mobile Broadband (xMBB), which provides the traffic volume and data transfer speeds required by applications such as virtual reality and augmented reality or ultra-high resolution 3D TVs. In this case, user device registration and capacity or capacity-based camping is performed (cell capacity or radio access capacity can be considered as one of the factors for prioritizing cells).

In FIG. 5b, another U-MTC case is presented. This is applicable to V2V or V2I (Vehicular to Infrastructure) communications. The user device is assumed to have an "infinite" power source as it is contained within the vehicle and is moving at medium or high speeds (not pedestrians). One approach to providing the required ultra-reliability is to use multiple connectivity to transmit the same data over multiple links. In this case, the access node is selected based on its ability to provide multiple connectivity. Another approach is to use information about mobility and / or service in the reconstruction to the intermediate state. When in the intermediate state, the user device can camp on the cell, perform tracking area procedures, and continuously monitor one or more paging channels. User devices camp on cells with wide area coverage and local access nodes are banned. The access node can provide a list of suitable cells for the user device. In this embodiment, information about mobility and / or service is used to avoid frequent handovers from one local cell to another. You can also combine these two approaches. The state of the user device in these cases is a connected / active state, an intermediate state, or an idle / disconnected state.

In order to quickly set up a connection to a secondary cell, the user device needs to keep up-to-date, for example, on the cell with the strongest average received signal power on layers of different frequencies. This information can be transferred as part of a connection request message transmitted to the master cell when the user device changes its state from, for example, an intermediate state to an active / connected state. Separate and up-to-date messages are also an option.

The steps / points, signaling messages and related functions described above in FIGS. 2, 3 and 4 are not in absolute order of occurrence and perform some of the steps / points simultaneously or in a different order than given. be able to. Other functions can be performed between steps / points, or even within steps / points, and other signaling messages can be sent between the illustrated messages. It is also possible to exclude some of the steps / points or parts of the steps / points or replace them with the corresponding steps / points or parts of the steps / points.

As used herein, to carry, broadcast, unicast, multicast, signal, transmit and / or receive means to prepare, carry, broadcast, transmit and / or receive data. Broadcasting, signaling, sending and / or preparing a message to be received, or physical sending and / or receiving itself, etc. can be meant on a case-by-case basis. The same principles apply to the terms transmit and receive.

One embodiment provides a device that can be a user device or any other suitable device capable of performing the processes described above in connection with FIG.

The device includes or is otherwise in communication with a control unit, one or more processors or other entities capable of performing the operations according to the embodiments described with reference to FIG.
