Description

[0001] background

[0002] The present invention relates to a method for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling the access of a user equipment to a telecommunication network, wherein the telecommunication network provides the user equipment with the use or activation of a plurality of different network slices and / or different network services.

[0003] Furthermore, the present invention relates to a system, a user equipment and a telecommunication network for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling access of a user equipment to a telecommunication network, wherein the telecommunication network provides the user equipment with use or activation of a plurality of different network slices and / or different network services.

[0004] Furthermore, the invention relates to a program comprising a computer-readable program code and to a computer-readable medium comprising instructions which, when executed, facilitate the performance of the method of the invention.

[0005] In a telecommunication network (typically a cellular mobile telecommunication network using a 4G or 5G system), the use of user-plane radio communication resources of the telecommunication network by (user equipment) and / or the access of the telecommunication network by (user equipment) is generally performed via a shared resource medium. In the telecommunication network, in an overload situation at least in parts of the network (i.e., typically in some network nodes or network components in the telecommunication network that are assigned to or responsible for a specific area or geographical area or for a specific kind (or group) of communication services or network slices), it is beneficial to take measures to reduce or at least not increase the overload situation.

[0006] Examples of such shared resource media in typical scenarios where a user equipment requests support or communication services or allocation or data transmission resources from a telecommunications network include scenarios where a user equipment requests use of user plane radio communication resources, e.g. by sending a grant request to the telecommunications network, and scenarios where a user equipment requests access to the telecommunications network, a random access channel such as a Random Access CHannel (RACH), which is a control channel used to acquire data transmission resources allocated by the telecommunications network.

[0007] Introducing the possibility for user equipment to use network slices (generally providing a higher flexibility of communication services using a telecommunication network; or other kinds of network services allowing a more granular provision of communication services to user equipment) also allows user equipment to request communication services in a number of different ways. The use of a specific network slice (out of a number of different network slices that can in principle be obtained within a telecommunication network) or the use of a number of network slices generally assumes that the corresponding user equipment is in a connected mode, generally having an RRC connection.

[0008] In order to prevent a user equipment or multiple user equipments from additionally accessing network resources that are already overloaded (or network resources that are at risk of being overloaded when requested to handle additional requests or traffic) (for example, in parts of a telecommunication network or for specific types (or groups) of communication services or network slices), it is beneficial to limit the ability of the user equipment involved, at least for certain user equipment or groups of user equipment and at least during a certain time interval, to request user-plane radio communication resources and / or access this shared medium or telecommunication network and also access such network resources (or shared medium) dedicated to a specific network slice or using at least one network slice provided by the telecommunication network.

[0009] Overview

[0010] The object of the present invention is to provide a method, system, user equipment and telecommunication network for selectively controlling the use of user-side radio communication resources of a telecommunication network and / or controlling the access of user equipment to the telecommunication network by introducing a suspension time interval into the control of the use of user-side radio communication resources and / or the control of access to the telecommunication network. The method according to the present invention particularly takes into account different traffic characteristics and / or communication service characteristics and / or user characteristics and provides enhanced control of user equipment requesting user-side radio communication resources and / or access to the telecommunication network by determining whether an attempt by (user equipment) to use the user-side radio communication resources of the telecommunication network and / or an attempt by (user equipment) to access the telecommunication network is allowed or not. In addition, the object of the present invention relates to a program including a computer-readable program code and a computer-readable medium including instructions that help perform the method of the present invention when executed.

[0011] The object of the invention is achieved by a method for controlling usage of user plane radio communication resources of a telecommunication network and / or for controlling access of a user equipment to a telecommunication network, wherein the telecommunication network provides usage or activation of a plurality of different network slices and / or different network services by a user equipment, wherein within at least one radio cell or radio coverage area within or being part of the telecommunication network a control channel data set is transmitted to the user equipment,

[0012] The method comprises the following steps:

[0013] In a first step, a plurality of specific hang time indications are transmitted to the user equipment as part of the control channel data set, wherein each of the plurality of specific hang time indications is associated with a different network slice and / or a different network service,

[0014] In a second step after the first step, use of user-plane radio communication resources of the telecommunication network and / or access of the user equipment to the telecommunication network is controlled by determining whether an attempt to use user-plane radio communication resources of the telecommunication network and / or an attempt to access the telecommunication network is allowed or not allowed, and the control is related to use of at least one of a plurality of different network slices and / or use of at least one of different network services.

[0015] The object of the invention is also achieved by a method for controlling usage of user plane radio communication resources of a telecommunication network and / or for controlling access of a user equipment to a telecommunication network, wherein the telecommunication network provides usage or activation of a plurality of different network slices and / or different network services by a user equipment, wherein within at least one radio cell or radio coverage area within the telecommunication network or being part of the telecommunication network a control channel data set is transmitted to the user equipment,

[0016] The method comprises the following steps:

[0017] In a first step, a plurality of specific hang time indications are transmitted to the user equipment as part of the control channel data set, wherein each of the plurality of specific hang time indications is associated with a different network slice and / or a different network service,

[0018] In a second step after the first step, control of use of user plane radio communication resources of the telecommunication network and / or access of the user equipment to the telecommunication network is performed by determining whether an attempt to use user plane radio communication resources of the telecommunication network and / or an attempt to access the telecommunication network is allowed or not allowed, wherein the control is related to use of at least one of a plurality of different network slices and / or use of at least one of the different network services, with respect to the user equipment,

[0019] In which, in a third step before the second step, the global hang-up time information is transmitted to the user equipment as part of the control channel data set, and the control in the second step is performed by combining the global hang-up time information and multiple specific hang-up time indications; or the user equipment is in a connected state during a time interval corresponding to the hang-up time interval.

[0020] According to the present invention, the use of user-plane radio communication resources of a telecommunication network and / or the access of a user equipment to a telecommunication network can be advantageously controlled in a manner that varies from user equipment to user equipment. Thus, an attempt by an individual user equipment to request user-plane radio communication resources of a telecommunication network and / or an attempt by an individual user equipment to obtain access to a telecommunication network can advantageously be suspended.

[0021] The introduction of network slicing is seen as an important improvement of the 5G mobile communication system to previously known mobile communication systems. Network slicing means providing a plurality of different virtual mobile communication networks, usually with different characteristics, on a common infrastructure of a mobile communication network (or telecommunication network). Examples of network slices with different characteristics include, for example, mobile broadband (MBB) or ultra-reliable low latency communication (URLLC). Typically, a given (or specific) user equipment or mobile terminal is able to use more than one network slice at a given moment, i.e., it is typically able to use a plurality of different network slices, such as, for example, up to two different network slices or up to three different network slices or up to four different network slices or up to five different network slices or up to six different network slices or up to seven different network slices or up to eight different network slices or up to nine different network slices or up to ten different network slices (or requesting user plane radio communication resources from the plurality of different network slices). Compared to 5G systems, previously deployed mobile communication systems also offer the possibility of providing different communication services to user equipment (or mobile terminals) in parallel, however, the user equipment (or mobile terminal) always has to be connected to the telecommunication network when in connected mode via only one logical connection (such as a radio resource control connection (RRC connection)) between the user equipment (or mobile terminal) on the one hand and the telecommunication network or a corresponding base station entity in its access network on the other hand. The basic concept of the logical connection of the user equipment to the telecommunication network via an RRC connection is also implemented in 5G systems, at least in principle.

[0022] In order to react to and / or avoid an actual or assumed overload situation within a telecommunication network or parts thereof, such as an overload situation in (parts of) an access network or network components thereof, such as a base station entity, an eNB (enhanced Node B) or a gNB (Next Generation Node B), there is a possibility to close (or terminate) the RRC connection of a specific (individual) user equipment (e.g., by means of an RRC connection release message as defined in the 3GPP TS 38.331 standardization document for NR and 3GPP TS 36.331 for enhanced LTE). Thereby, it is even possible to (hard) interrupt an ongoing (or active) transmission of (user plane) data of a unique or specific user equipment within the telecommunication network. However, typically the RRC connection remains active (or active) for a longer period of time (until the expiration of a timer, such as an RRC timeout timer, is reached) so that the user equipment can transmit data to (and / or receive data from) the telecommunication network without the additional delay of (newly) establishing the RRC connection (or an RRC connection) between the specific user equipment and the telecommunication network.

[0023] In conventional known 4G communication systems (e.g., LTE), in an overload situation, the RRC connection between the telecommunication network and the user equipment will be interrupted, and the user equipment will need to send an RRC connection request in order to newly connect to the telecommunication network. The telecommunication network (or its access network or corresponding base station entity or eNodeB) will then be able to restrict the user equipment from reconnecting to the network, for example by using the access class restriction principle defined in the 3GPP TS 36.331 standardization document. However, as defined by the 3GPP standard, this access class restriction concept is invalid for an already existing RRC connection.

[0024] According to the present invention, the use of user-plane radio communication resources of a telecommunication network and / or the access of a user equipment to the telecommunication network is controlled by imposing a suspension time interval on the user equipment (before a large amount of data transmission resources of the telecommunication network can be used or before access to the telecommunication network can be requested again). It is assumed that the telecommunication network provides for the use or activation of multiple different network slices and / or different network services (typically the multiple network slices and / or different network services are activated by the user equipment or at the request of the user equipment, or alternatively the multiple network slices and / or different network services are activated by the telecommunication network through a default policy). It is further assumed that a control channel data set is transmitted to the user equipment at least within a radio cell or radio coverage area within the telecommunication network or as part of the telecommunication network. As part of the control channel data set, in a first step of the method of the present invention, the user equipment receives (i.e., the telecommunication network or its access network, in particular the corresponding base station entity or gNB transmits) multiple specific suspension time indications, wherein each of the multiple specific suspension time indications is related to different network slices and / or different network services of the telecommunication network, for example, the first specific suspension time indication is related to the first network slice, the second specific suspension time indication is related to the second network slice, and the third specific suspension time indication is related to the third network slice,..., the eighth specific suspension time indication is related to the eighth network slice.

[0025] By means of specific suspension time indications, each of which indicates (or corresponds to or includes) information defining a suspension time interval (related to the use of one of a plurality of different network slices and / or the use of one of the different network services), the use of user-plane radio communication resources of the telecommunications network can be advantageously controlled according to the present invention. Alternatively or additionally, by means of specific suspension time indications, each of which indicates (or corresponds to or includes) information defining a suspension time interval, the access of user equipment to the telecommunications network (related to the use of one of a plurality of different network slices and / or the use of one of the different network services) can be advantageously controlled according to the present invention. This actually means determining whether an attempt to use user-plane radio communication resources of a telecommunication network and / or an attempt to access the telecommunication network is allowed or not, i.e.: within (or during) a suspension time interval, an attempt by a user equipment to use user-plane radio communication resources of the telecommunication network (related to corresponding use of one of the different network slices and / or one of the different network services) is not allowed, and / or also within (or during) a suspension time interval, an attempt by a user equipment to access the telecommunication network (related to corresponding use of one of the different network slices and / or one of the different network services) is not allowed, and after expiration of the suspension time interval, an attempt by the user equipment to use user-plane radio communication resources of the telecommunication network (related to corresponding use of one of the different network slices and / or one of the different network services) is allowed, and / or also after expiration of the suspension time interval, an attempt by the user equipment to access the telecommunication network (related to corresponding use of one of the different network slices and / or one of the different network services) is allowed. In the context of the present invention, embodiments of the present invention are particularly preferred so that, as has been said several times, by means of a specific suspension time indication, a specific suspension time interval associated with the use of one of a plurality of different network slices and / or associated with the use of one of the different network services can be defined. However, this does not necessarily mean that the specific suspension time indication is limited to being associated with the use of one and only one network slice of a plurality of different network slices and / or associated with the use of one and only one network service of the different network services.According to a further embodiment of the present invention, it is possible and preferred to be able to define specific suspension time intervals related to the use of more than one network slice (but still a subset) of a plurality of different network slices and / or related to the use of more than one network service (but still a subset) of different network services, in particular in case the number of network slices in use within (or in connection with) a telecommunication network and / or in use or potentially in use with the telecommunication network increases; therefore, it is possible to define groups (or at least one group) of network slices (or to define groups (or at least one group) of network services), each group of network slices (or network services) comprising more than one network slice (or network service), wherein for the entire group of network slices (or network services), one specific suspension time indication (out of a plurality of specific suspension time indications) (together with the global suspension time information, if applicable) defines a suspension time interval to be applied to all network slices (or all network services) in the group.

[0026] According to the present invention, the suspension time interval associated with the corresponding use of one of the different network slices and / or one of the different network services (using the user-plane radio communication resources of the telecommunication network or accessing the telecommunication network) can be directly defined by the corresponding specific suspension time indication (among multiple specific suspension time indications) (i.e., each specific suspension time indication specifies its corresponding suspension time interval), or includes code information referring to the corresponding suspension time interval.

[0027] Thus, a relatively high degree of flexibility in assigning and transmitting information about suspension time intervals that may be applicable to each different network slice and / or network service may be achieved.

[0028] Alternatively, according to another embodiment of the present invention, in a third step before the second step, the global hang-up time information is transmitted to the user equipment as part of the control channel data set, and the control in the second step is performed by combining the global hang-up time information and multiple specific hang-up time indications.

[0029] Thus, the suspension time interval can be advantageously determined based on these two information components, namely the global suspension time information and the specific suspension time indication. Thus, the amount of data transmitted for transmitting information about the suspension time interval for each different network slice and / or network service can be advantageously reduced.

[0030] According to the present invention, it is further preferred that: each or at least one of the multiple specific suspension time indications indicates whether the global suspension time information will be applied to the corresponding network slice, thereby resulting in the user equipment of the corresponding network slice being restricted from using the user plane radio communication resources of the telecommunication network or attempting to access the telecommunication network during the suspension time interval corresponding to the global suspension time information, if the corresponding specific suspension time indication for the corresponding network slice and / or different network services so indicates.

[0031] Thus, it is essentially possible to advantageously define an applicable hang time interval (by transmitting global hang time information) and be able to determine (or indicate so by transmitting a specific hang time indication which in its most basic way corresponds to a single bit of information) whether an applicable hang time will apply (apply to the corresponding network slice and / or network service) for each different network slice and / or different network service.

[0032] According to a further preferred embodiment of the present invention, each or at least one of the multiple specific suspension time indications is factor information or includes factor information, which will be applied to the corresponding network slice, thereby causing the user equipment of the corresponding network slice to be restricted from using user-plane radio communication resources of the telecommunication network or attempting to access the telecommunication network during a suspension time interval corresponding to the global suspension time information multiplied by the factor to be applied to the corresponding network slice, and the factor is indicated by the factor information in the specific suspension time indication.

[0033] Thus, it is possible to advantageously use not only a single applicable suspension time interval (which will be (fully) applied or not applied at all), but also to apply different suspension time intervals for each different network slice and / or different network service, and to transmit the corresponding information in an efficient manner to save transmission resources.

[0034] According to another preferred embodiment of the present invention, each of the plurality of specific suspension time indications is at least one of the following or includes at least one of the following:

[0035] A one-bit indication of whether the global suspension time information will be applied to one of multiple network slices and / or one of different network services, and factor information to be applied to one of multiple network slices and / or one of different network services, wherein the suspension time interval corresponds to the global suspension time information multiplied by the factor, which will be applied to the corresponding network slice and indicated by the specific suspension time information or its factor information.

[0036] Therefore, according to the present invention, different possibilities of what a specific suspension time indication corresponds to may also be mixed, i.e., for example, for a first network slice, the corresponding first specific suspension time indication corresponds to a one-bit value (indicating whether the suspension time interval (defined by the global suspension time information) is to be applied), and for a second network slice, the corresponding second specific suspension time indication corresponds to factor information so that the suspension time interval is obtained by multiplying the time interval corresponding to the global suspension time information by a factor to be applied to the corresponding network slice, the factor being indicated by the factor information in the specific suspension time indication.

[0037] According to the present invention, it is further preferred that the global hang-up time information on the one hand and the multiple specific hang-up time indications on the other hand are transmitted as part of a subset of control channel data to be transmitted to the user equipment or as part of different subsets of control channel data to be transmitted to the user equipment (in particular transmitted at different time points).

[0038] According to the present invention, a plurality of specific hang-up time indications as well as global hang-up time information can thus advantageously be transmitted flexibly.

[0039] According to yet another preferred embodiment of the present invention, the user equipment is in a connected state during a time interval corresponding to the suspension time interval, and in particular, a radio resource control connection of the user equipment is not interrupted.

[0040] Thereby, there may advantageously be no need to reestablish a radio resource control connection between the user equipment and the access network of the telecommunications network (after having been closed due to an overload situation within the telecommunications network). Thus, advantageously and despite the fact that the radio resource control connection is not necessarily released, the overload situation can still be handled by the telecommunications network by individually (i.e. on a per user equipment basis) allowing or not allowing the use of one or more specific network slices or network services (and another one or more other network slices or network services still being suspended (for a longer or shorter time interval) from being used by the user equipment).

[0041] Therefore, according to the present invention, the need to completely interrupt the radio resource control connection (via a general RRC connection release message) just to be able to suspend (one or more user equipment) use of one or more network slices or network services can be advantageously avoided. With respect to an embodiment of the present invention in which the user equipment should not leave the connected state during a time interval corresponding to the suspension time interval (i.e., during this time interval, the RRC connection of the user equipment is maintained), the method of the present invention relates to controlling the use of user-plane radio communication resources by the user equipment (and generally does not involve controlling the user equipment's access to the telecommunications network, as this access is already provided through the user equipment's existing RRC connection). Similarly, multiple specific suspension time indications (and global suspension time information, if applicable) are intended to relate to controlling the use of user-plane radio communication resources by the user equipment (i.e., generally does not involve controlling the user equipment's access to the telecommunications network).

[0042] However and also according to the present invention, it is not excluded that the radio resource control connection between the user equipment and the telecommunication network (or its access network) is indeed (completely) interrupted (or released), which is the case under normal circumstances (i.e., in this implementation, overload control is performed so that the RRC connection of these user equipments that are at least temporarily blocked is indeed (forced) released). In this situation (the radio resource control connection of the user equipment is completely interrupted), the value of the suspension time interval that must be passed before the user equipment is allowed to attempt to access the telecommunication network again can be advantageously indicated to the user equipment by a specific suspension time indication (alone) or both global suspension time information and a specific suspension time indication with respect to the corresponding network slice and / or network service; therefore, access control of the user equipment to the telecommunication network is provided. Therefore, according to this preferred embodiment of the present invention, the user equipment is in a disconnected state (or idle state) during a time interval corresponding to the suspension time interval. In this implementation, in particular, the specific suspension time indications (related to the corresponding network slice or network service) that are supplementary to the global suspension time information are all intended to indicate or define a suspension time interval that varies from network slice to network slice and is applicable to the access (reestablishment) of the user equipment to the telecommunication network (i.e., the access is not allowed when the suspension time interval has not yet passed, and the access is allowed once the suspension time interval has passed). Therefore, in this implementation, the method of the present invention relates to controlling the access of the user equipment to the telecommunication network (but not to controlling the use of user-plane radio communication resources by the user equipment). Similarly, multiple specific suspension time indications (and global suspension time information, if applicable) are intended to relate to controlling the access of the user equipment to the telecommunication network (and to controlling the use of user-plane radio communication resources by the user equipment).

[0043] According to a further preferred embodiment of the invention, the use of user plane radio communication resources of the telecommunication network by the user equipment corresponds to reception of payload data and / or user plane data by the user equipment from the telecommunication network and / or transmission of payload data and / or user plane data by the user equipment to the telecommunication network.

[0044] Thereby, the control of the radio communication resources can advantageously be applied to user plane radio communication resources, ie payload data and / or user plane data.

[0045] The present invention also relates to a system for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling access of user equipment to a telecommunication network, the system comprising user equipment and a telecommunication network, wherein the telecommunication network provides the user equipment with use or activation of a plurality of different network slices and / or different network services, wherein within the telecommunication network or within at least one radio cell or radio coverage area as part of the telecommunication network, the system is configured such that a control channel data set is transmitted to the user equipment via the telecommunication network, wherein the system is configured such that: a plurality of specific suspension time indications are transmitted as part of the control channel data set and via the telecommunication network to the user equipment, wherein each of the plurality of specific suspension time indications is associated with a different network slice and / or a different network service,

[0046] The system is configured to control the use of user-plane radio communication resources of the telecommunication network by determining whether an attempt by the user equipment to use the user-plane radio communication resources of the telecommunication network is allowed or not allowed and / or to control the user equipment's access to the telecommunication network by determining whether an attempt by the user equipment to access the telecommunication network is allowed or not allowed, the control being related to the use of at least one of a plurality of different network slices and / or the use of at least one of different network services.

[0047] The present invention also relates to a system for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling access of user equipment to a telecommunication network, the system comprising user equipment and a telecommunication network, wherein the telecommunication network provides the user equipment with use or activation of a plurality of different network slices and / or different network services, wherein within the telecommunication network or within at least one radio cell or radio coverage area as part of the telecommunication network, the system is configured such that a control channel data set is transmitted to the user equipment via the telecommunication network, wherein the system is configured such that: a plurality of specific suspension time indications are transmitted as part of the control channel data set and via the telecommunication network to the user equipment, wherein each of the plurality of specific suspension time indications is associated with a different network slice and / or a different network service,

[0048] wherein the system is configured to control usage of user plane radio communication resources of the telecommunications network with respect to the user equipment by determining whether an attempt by the user equipment to use user plane radio communication resources of the telecommunications network is allowed or not allowed and / or to control access of the user equipment to the telecommunications network by determining whether an attempt by the user equipment to access the telecommunications network is allowed or not allowed, the control being related to usage of at least one of a plurality of different network slices and / or usage of at least one of different network services,

[0049] The global hang-up time information is transmitted to the user equipment as part of a control channel data set, and the control in the second step is performed by combining the global hang-up time information and multiple specific hang-up time indications; or the user equipment is in a connected state during a time interval corresponding to the hang-up time interval.

[0050] Thus, a system is provided for controlling the use of user plane radio communication resources of a telecommunications network and / or access of a user equipment to a telecommunications network by imposing a suspension time interval on the user equipment (before bulk data transmission resources of the telecommunications network can be used or before access to the telecommunications network can be requested again).

[0051] In particular, as part of the system of the present invention, the present invention also relates to a user equipment for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling the access of the user equipment to the telecommunication network, wherein the user equipment is adapted to use or activate a plurality of different network slices and / or different network services of the telecommunication network, wherein the user equipment is configured such that within at least one radio cell or radio coverage area within the telecommunication network or as part of the telecommunication network, a control channel data set transmitted via the telecommunication network is received by the user equipment, wherein the user equipment is further configured such that: a plurality of specific suspension time indications are received as part of the control channel data set by the user equipment The user equipment receives, wherein each of the multiple specific suspension time indications is related to a different network slice and / or a different network service, wherein the user equipment is configured to control the use of user-plane radio communication resources of the telecommunication network by determining whether an attempt by the user equipment to use user-plane radio communication resources of the telecommunication network will be allowed or not and by limiting such attempt to only allowed attempts and / or to control access to the telecommunication network by determining whether an attempt to access the telecommunication network will be allowed or not and by limiting such attempt to only allowed attempts, the control being related to the use of at least one of the multiple different network slices and / or the use of at least one of the different network services.

[0052] In particular, as part of the system of the present invention, the present invention also relates to a user equipment for controlling the use of user-plane radio communication resources of a telecommunication network and / or for controlling the access of the user equipment to the telecommunication network, wherein the user equipment is adapted to use or activate a plurality of different network slices and / or different network services of the telecommunication network, wherein the user equipment is configured such that within at least one radio cell or radio coverage area within the telecommunication network or as part of the telecommunication network, a control channel data set transmitted via the telecommunication network is received by the user equipment, wherein the user equipment is further configured such that: a plurality of specific suspension time indications are received as part of the control channel data set by the user equipment receiving, by a user equipment, each of the plurality of specific hang-time indications relating to a different network slice and / or a different network service, wherein the user equipment is configured to control usage of user plane radio communication resources of the telecommunication network by determining whether an attempt by the user equipment to use user plane radio communication resources of the telecommunication network is to be allowed or not allowed and by limiting such attempt to only allowed attempts and / or to control access to the telecommunication network by determining whether an attempt to access the telecommunication network is to be allowed or not allowed and by limiting such attempt to only allowed attempts, the controlling relating to usage of at least one of the plurality of different network slices and / or usage of at least one of the different network services,

[0053] The global hang-up time information is received by the user equipment as part of a control channel data set, and the control in the second step is performed by combining the global hang-up time information and multiple specific hang-up time indications; or the user equipment is in a connected state during a time interval corresponding to the hang-up time interval.

[0054] Thus, a user equipment is provided, via which use of user-plane radio communication resources of a telecommunications network and / or access of the user equipment to the telecommunications network can be controlled by imposing on the user equipment a suspension time interval to be elapsed before the user equipment can use bulk data transmission resources of the telecommunications network or before access to the telecommunications network can be requested again.

[0070] The present invention will be described with respect to specific embodiments and with reference to certain drawings, but the invention is not limited thereto but only by the claims. The drawings described are only schematic and non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn to scale for illustrative purposes.

[0071] Where an indefinite or definite article is used when referring to a singular noun (eg "a", "an", "the"), this includes a plural of that noun unless something else is specifically stated.

[0072] Furthermore, the terms first, second, third, etc., in the specification and in the claims are used to distinguish between similar elements and not necessarily to describe a sequential or temporal order. It should be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0073] According to the present invention, an improved method is disclosed for controlling the use of user plane radio communication resources of a telecommunication network and / or the access of a user equipment to the telecommunication network in a network slice-dependent (or network slice-specific) manner. According to the present invention, it is assumed that the telecommunication network 200 provides for the use or activation of a plurality of different network slices 300, 301, 302 and / or different network services.

[0074] exist Figure 1In the figure, a user equipment 100 is schematically shown connected to a telecommunication network 200 (or to a base station entity, such as for example an eNodeB or gNodeB entity, which is part of an access network of the telecommunication network 200). In a conventionally known manner, the telecommunication network 200 is a cellular mobile communication network comprising an access network (not specifically shown) (and typically also a core network), and the access network typically comprises a plurality of base station entities, such as eNodeB and / or gNodeB base station entities, which in a conventionally known manner serve radio cells, i.e. the radio coverage areas of these base station entities.

[0075] Furthermore, in a conventionally known manner, at least within one radio cell or radio coverage area within the telecommunication network 200 or being part of the telecommunication network 200, a control channel data set is transmitted to the user equipment 100.

[0076] As already mentioned, the user equipment 100 is able to use a plurality of different network slices 300, 301, 302 of the telecommunication network 200 or provided by the telecommunication network 200 (or it is able to use a plurality of different network services). Figure 1 In the exemplary representation of FIG. 1 , three network slices are schematically shown, namely a first network slice 300, a second network slice 301 and a third network slice 302. According to the present invention, the only limitation on the number of network slices 300, 301, 302 is the possibility of the telecommunication network 200 providing or managing (and the user equipment 100 disposing, if applicable) the network slices 300, 301, 302. In principle, a typical ideal number of network slices 300, 301, 302 to be provided and / or activated by the telecommunication network 200 and / or by the user equipment 100 may be eight network slices, but according to the present invention, an increased number of these network slices, such as nine, ten, eleven or twelve network slices, is also possible.

[0077] In 5G networks, network slicing allows customers to enjoy connectivity and data processing customized for specific needs (for example, in accordance with the service level agreement reached with the operator of the telecommunications network), and customizable network capabilities generally include one or more of the following: data speed, quality, latency, reliability, security, and service. From the perspective of mobile operators, network slices are independent end-to-end logical networks that can provide negotiated quality of service running on shared physical infrastructure. The technology that enables network slicing is transparent to customers of the network. Network slices can span multiple parts of the network (for example, terminals, access networks, core networks, and transport networks) and can also be deployed across multiple operators. Network slices include dedicated and / or shared resources in terms of processing power, storage, and bandwidth, and generally have the possibility of isolation from other network slices. Slice types can be defined from a functional or behavioral perspective. Mobile network operators are able to deploy a single network slice type that meets the needs of multiple vertical industries and multiple network slices of different types that are packaged as a single product (service package) for enterprise customers with multiple different needs (for example, a vehicle may need a high-bandwidth slice for infotainment and an ultra-reliable slice for telemetry-based assisted driving at the same time).

[0078] According to the method of the present invention, the use of user-plane radio communication resources of the telecommunication network 200 by the user equipment 100 can be controlled more efficiently than conventional known methods. In particular, in the case of network overload (or assumed or expected network overload) in a smaller or larger part (or geographical area) of the telecommunication network 200 (for example, involving one or more different radio cells of the telecommunication network 200), there is a need for a method to effectively reduce such network load, in particular the network load caused by user equipments that trigger or request user-plane data transmission to and / or from the telecommunication network 200 (these user equipments 100 are usually located in the corresponding part or geographical area experiencing the network overload). According to an embodiment of the present invention, the use of user-plane radio communication resources of the telecommunication network 200 is controlled by applying a network slice-dependent (or network slice-specific) suspension time interval 700 to the user equipment 100, i.e., before the user equipment 100 can use a large amount of data transmission resources of the telecommunication network 200 (involving the use of a specific network slice and / or the use of a specific network service), the suspension time interval 700 (for the specific network slice and / or the specific network service) needs to have passed.

[0079] According to the present invention, for enhanced and more efficient control of the use of user-plane radio communication resources of the telecommunication network 200, it is particularly advantageous that the user equipment 100 remains connected during the time interval corresponding to the suspension time interval 700, in particular without interrupting the radio resource control connection of the user equipment 100. Therefore, since the application (or application) of the suspension time interval 700 does not necessarily require closing the radio resource control connection, the radio resource control connection between the user equipment 100 and the access network of the telecommunication network 200 does not need to be reestablished, thereby avoiding the overhead traffic and network and user equipment resources that would otherwise be necessary. Therefore, according to the present invention, it is still possible to advantageously handle overload situations by the telecommunication network 200 by individually (i.e., on a per-user-equipment basis) allowing or not allowing the use of one or more specific network slices 300, 301, 302 or network services (and one or more other network slices or network services are still suspended (for a longer or shorter time interval) to prevent use by the user equipment 100).

[0080] However, even if a (complete) release of the radio resource control connection between the user equipment 100 and the telecommunication network 200 occurs, according to the present invention it is possible to control the access of the user equipment 100 to the telecommunication network 200 more efficiently (compared to conventionally known methods). According to an additional embodiment of the present invention, the access of the user equipment 100 to the telecommunication network 200 is controlled by imposing a network slice-dependent (or network slice-specific) suspension time interval 700 on the user equipment 100, i.e., before the user equipment 100 is able to access the telecommunication network 200 (involving the use of a specific network slice and / or the use of a specific network service), the suspension time interval 700 (for the specific network slice and / or the specific network service) needs to have passed.

[0081] However, with respect to all embodiments according to the present invention, information about the suspension time interval 700 to be applied in a network slice-dependent manner needs to be transmitted to the user equipment 100. As part of the control channel data set (not specifically shown), in a first step of the method of the present invention, the user equipment 100 receives (i.e., the telecommunication network 200 or its access network, in particular the corresponding base station entity or gNodeB transmits) a plurality of specific suspension time indications 500, 600, wherein each of the plurality of specific suspension time indications 500, 600 is related to a different network slice 300, 301, 302 and / or a different network service of the telecommunication network 200, for example, the first specific suspension time indication is related to the first network slice 300, the second specific suspension time indication is related to the second network slice 301, and the third specific suspension time indication is related to the third network slice 302. For two exemplary scenarios, this is Figure 2 and 3 It is schematically shown in: Figure 2In FIG. 1 , a first exemplary scenario of indicating a suspension time interval 700 by means of global suspension time information 400 and a plurality of specific suspension time indications 500 is schematically shown, and in FIG. Figure 3 In FIG. 4 , a second exemplary scenario of indicating a suspension time interval 700 by means of global suspension time information 400 and a plurality of specific suspension time indications 600 is schematically illustrated.

[0082] according to Figure 2 In the first exemplary scenario represented in FIG. 1 , the specific suspension time indication 500 indicates for the corresponding network slice 300, 301, 302 whether the global suspension time information 400 is to be applied (i.e., the specific suspension time indication 500 essentially corresponds to or includes a one-bit value), and the suspension time interval 700 for the corresponding network slice 300, 301, 302 corresponds to the global suspension time information 400 for these network slices 300, 301, 302 (indicating a value of, for example, “30 seconds”), and the corresponding specific suspension time indication 500 indicates that the global suspension time information 400 should be applied to these network slices 300, 301, 302 (in the Figure 2 In the exemplary scenario represented in , this is true for the first and second network slices 300, 301, but not for the third network slice).

[0083] according to Figure 3 In the second exemplary scenario represented in , the specific suspension time indication 600 is or includes factor information to be applied to the corresponding network slice 300, 301, 302. As a result, for the corresponding network slice 300, 301, 302, the user equipment 100 is restricted from using the user plane radio communication resources of the telecommunication network 200 during the suspension time interval 700, and the suspension time interval corresponds to the global suspension time information 400 multiplied by the factor to be applied to the corresponding network slice 300, 301, 302, which factor is indicated by the factor information of the specific suspension time indication 600. Figure 3 In the exemplary scenario represented in , the specific suspension time indication for the first network slice 300 indicates (through the corresponding factor information) for example a factor of 0.1, thereby generating a suspension time interval of 3 seconds based on (as in the first exemplary scenario) the global suspension time information 400 indicating a value of, for example, 30 seconds. The specific suspension time indication for the second network slice 301 indicates for example a factor of 2, thereby generating a suspension time interval of 60 seconds based on the global suspension time information 400 indicating a value of, for example, 30 seconds. The specific suspension time indication for the third network slice 302 indicates for example a factor of 5, thereby generating a suspension time interval of 150 seconds based on the global suspension time information 400 indicating a value of, for example, 30 seconds.

[0084] even though Figure 2 and3 Both schematically represent exemplary embodiments involving the transmission of global suspension time information 400, but this global suspension time information is not necessarily required: according to other embodiments of the present invention (not specifically shown in the figures), the specific suspension time indications 500, 600 respectively include indications about the suspension time interval 700 to be applied to the corresponding network slice 300, 301, 302 or the corresponding network service.

[0085] Furthermore, different possibilities of what the specific suspension time indications 500, 600 correspond to may also be mixed, i.e., for example, for the first network slice 300, the corresponding first specific suspension time indication 500 corresponds to a one-bit value (indicating whether the suspension time interval 700 (defined by the global suspension time information 400) is to be applied), and for the second network slice 301, the corresponding second specific suspension time indication 600 corresponds to factor information so that the suspension time interval 700 is obtained by multiplying the time interval corresponding to the global suspension time information 400 by a factor to be applied to the corresponding network slice, the factor being indicated by the factor information in the specific suspension time indication 600.
