Patent Description:
Furthermore, the present invention relates to a system, user equipment, and telecommunications network for controlling the use of user plane radio communication resources of a telecommunications network and/or for controlling the access of a user equipment to a telecommunications network, wherein the telecommunications network provides the use or activation, by the user equipment, of a plurality of different network slices and/or of different network services.

Additionally, the present invention relates to a program comprising a computer readable program code, and to a computer-readable medium comprising instructions which when executed help to perform an inventive method.

In telecommunications networks, typically cellular mobile telecommunications networks using <NUM> or <NUM> systems, the use (by a user equipment) of user plane radio communication resources of the telecommunications network and/or the access (by a user equipment) to the telecommunications network is normally performed via a shared resource medium. In case of an overload situation in the telecommunications network, at least in parts thereof, i.e. typically in parts of the network nodes or network components of the telecommunications network assigned to or responsible for a certain region or geographical area, or for a certain kind (or groups) of communication service(s) or network slice(s), measures to either reduce or at least not increase the overload situation are beneficial to be taken. Reference is made to the following documents: <CIT> and <CIT>.

Examples of such shared resource media in typical situations of a user equipment requesting support or a communication service from the telecommunications network or the allocation or data transmission resources include,.

The introduction of the possibility for a user equipment to use network slices (typically providing a higher degree of flexibility of using communication services of the telecommunications network; or other kinds of network services providing for a more fine grained provision of communication service to the user equipment) also allows a user equipment to request communication services in a plurality of different ways. The use of a specific network slice (of a plurality of different network slices that are, in principle, available within the telecommunications network), or the use of a plurality of network slices typically presumes that the respective user equipment is in a connected mode, typically has an RRC connection.

In order to prevent a user equipment or a plurality of user equipments from additionally accessing already overloaded network resources (or network resources risking to be overloaded when requested to handle additional requests or traffic), e.g. in parts of the telecommunications network or for a certain kind (or groups) of communication service(s) or network slice(s), it is beneficial to limit the involved user equipments in their ability to request user plane radio communication resources and/or access to such shared media or to the telecommunications network - and also to such network resources (or shared media) that are specific to the use of certain network slices or to the use of at least one network slice provided by the telecommunications network -, at least for certain user equipments or groups thereof, and at least for a certain time interval.

An object of the present invention is to provide a method, a system, a user equipment, and a telecommunications network for selectively controlling the use of user plane radio communication resources of a telecommunications network and/or for controlling the access of a user equipment to a telecommunications network by means of introducing a suspend time interval to control of the use of user plane radio communication resources and/or the control of the access to the telecommunications network. The method according to the present invention especially takes into account different traffic characteristics and/or communication service characteristics and/or user characteristics and provides an enhanced control of the user equipments requesting user plane radio communication resources and/or access to the telecommunications network by taking a decision whether an attempt (of a user equipment) to use user plane radio communication resources of the telecommunications network and/or whether an attempt (of a user equipment) to access the telecommunications network is allowed or disallowed. Additionally, objects of the present invention relate to a program comprising a computer readable program code, and to a computer-readable medium comprising instructions which when executed help to perform an inventive method.

The object of the present invention is achieved by a method for controlling the use of user plane radio communication resources of a telecommunications network and/or for controlling the access of a user equipment to a telecommunications network according to claim <NUM>.

The object of the present invention is also achieved by a method for controlling the use of user plane radio communication resources of a telecommunications network and/or for controlling the access of a user equipment to a telecommunications network, wherein the telecommunications network provides the use or activation, by the user equipment, of a plurality of different network slices and/or of different network services, wherein - within at least one radio cell or radio coverage area within or as part of the telecommunications network - a set of control channel data is transmitted to the user equipment,.

According to the present invention, it is advantageously possible to control the use of user plane radio communication resources of the telecommunications network and/or for controlling the access of the user equipment to the telecommunications network in a user equipment specific manner. Thereby, it is advantageously possible to suspend attempts to request user plane radio communication resources of the telecommunications network by an individual user equipment and/or attempts to gain access to the telecommunications network by an individual user equipment.

The introduction of network slicing is seen as an important improvement of <NUM> mobile communication systems over previously known mobile communication systems. Network slicing means the provision of a plurality of different virtual mobile communication networks, typically having different characteristics, on a common infrastructure of a mobile communication system (or telecommunications network). Examples of network slices of different characteristics include, e.g., Mobile Broadband (MBB), or Ultra-Reliable Low-Latency Communication (URLLC). Typically, a given (or specific) user equipment or mobile terminal is able to use, at a given moment in time, more than one network slice simultaneously, i.e. it is typically able to use (or request user plane radio communication resources from) a plurality of different network slices, such as, e.g., a maximum of two different network slices, or a maximum of three different network slices or a maximum of four different network slices or a maximum of five different network slices or a maximum of six different network slices or a maximum of seven different network sliced or a maximum of eight different network slices or a maximum of nine different network slices or a maximum of ten different network slices. Previously deployed mobile communication systems, compared to <NUM> systems, also provided the possibility to provide different communication services, in parallel, to a user equipment (or mobile terminal), however, a user equipment (or mobile terminal) - while being in a connected mode - always had to be connected to the telecommunications network by means of only one logical connection, such as a radio resource control connection (RRC connection) between, on the one hand, the user equipment (or mobile terminal), and, on the other hand, the telecommunications network or the respective base station entity of its access network. This basic concept of a logical connection of a user equipment to the telecommunications network by means of an RRC connection is, at least in principle, also realized in <NUM> systems. In order to react with respect to and/or avoid actual or presumed overload situations within the telecommunications network or parts thereof (such as overload situations in (parts of) the access network or network components thereof, such as base station entities, eNBs (enhanced NodeBs) or gNBs (next generation NodeBs)), there is the possibility to close (or to terminated) the RRC connection of certain (individual) user equipments (e.g. by means of the RRC connection release message, defined in the 3GPP TS <NUM> standardization document for NR and 3GPP TS <NUM> for enhanced LTE). Thereby, it is even possible to (hard) interrupt an ongoing (or active) transmission of (user plane) data of a peculiar or specific user equipment within the telecommunications network. However, typically an RRC connection is maintained active (or alive) for a longer period of time (until the end of a timer is reached, such as an RRC time out timer) in order for the user equipment to be able to transmit data to the telecommunications network (and/or receive data from the telecommunications network) without the additional delay of (newly) establishing the (or an) RRC connection between the specific user equipment and the telecommunications network.

In a conventionally known <NUM> communication system (e.g. LTE), in case of an overload situation, the RRC connection between the telecommunications network and a user equipment would interrupted, and the user equipment would need to send an RRC connection request in order to get newly connected to the telecommunications network. The telecommunications network (or its access network or the respective base station entity or eNodeB) would then be able to restrict the user equipment from reconnecting to the network, e.g. by using the access class barring principle defined in the 3GPP TS <NUM> standardization document. However, as defined by the 3GPP standards, this access class barring concept is not valid for already existing RRC connections.

According to the present invention, the use of user plane radio communication resources of a telecommunications network and/or the access of a user equipment to a telecommunications network is controlled by imposing a suspend time interval to the user equipment (prior to be able to either use substantial data transmission resources of the telecommunications network, or prior to be able to again request access to the telecommunications network). It is assumed that the telecommunications network provides the use or activation of a plurality of different network slices and/or of different network services (typically this plurality of network slices and/or of different network services are either activated by the user equipment or upon request of the user equipment, or, alternatively, this plurality of network slices and/or of different network services are activated by default policy by the telecommunications network). It is furthermore assumed that - at least within one radio cell or radio coverage area within or as part of the telecommunications network - a set of control channel data is transmitted to the user equipment. As part of this set of control channel data the user equipment receives (i.e. the telecommunications network, or, its access network, especially the respective base station entity, or gNB, transmits), in a first step of the inventive method, a plurality of specific suspend time indications, wherein each one of the plurality of specific suspend time indications relates to a different network slice and/or to a different network service of the telecommunications network, e.g. a first specific suspend time indication relating to a first network slice, a second specific suspend time indication relating to a second network slice, and a third specific suspend time indication relating to a third network slice,. , an eighth specific suspend time indication relating to an eighth network slice.

By means of the specific suspend time indications, each one indicating (or corresponding to or comprising) an information defining a suspend time interval (related to the use of one of the plurality of different network slices and/or to the use of one of the different network services), it is advantageously possible according to the present invention to control the use of user plane radio communication resources of the telecommunications network. Alternatively or cumulatively, by means of the specific suspend time indications, each one indicating (or corresponding to or comprising) an information defining a suspend time interval, it is advantageously possible according to the present invention to control the access of the user equipment to the telecommunications network regarding the use of one of the plurality of different network slices and/or to the use of one of the different network services. This actually means that it is decided whether an attempt to use user plane radio communication resources of the telecommunications network and/or whether an attempt to access the telecommunications network is allowed or disallowed, i.e.:.

In the context of the present invention, embodiments of the present invention are especially preferred such that - as has already been stated a certain number of times - by means of the specific suspend time indications, a specific suspend time interval is able to be defined related to the use of one of the plurality of different network slices and/or related to the use of one of the different network services. However, this does not necessarily mean that the specific suspend time indications are limited to relate to the use of one and only one of the plurality of different network slices and/or to relate to the use of one and only one of the different network services: According to further embodiments of the present invention, it is possible and preferred - especially in case of an increase of the number of network slices in use within (or in connection with) the telecommunications network and/or in use, or potentially in use, with the telecommunications network - that a specific suspend time interval is able to be defined related to the use of more than one (but still a subset) of the plurality of different network slices and/or related to the use of more than one (but still a subset) of the different network services; hence, 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 of network services) comprising more than one network slices (or network services), wherein for the entire group of network slices (or of network services) one specific suspend time indication (of the plurality of the specific suspend time indications) - if applicable together with the global suspend time information - defines the suspend time interval to be applied for all the network slices (or all the network services) in the group.

According to the present invention, the suspend time interval relating to the respective use of one of the different network slices and/or one of the different network services (to use user plane radio communication resources of the telecommunications network, or to access the telecommunications network) might either be defined directly by means of the corresponding specific suspend time indication (of the plurality of specific suspend time indications), i.e. each specific suspend time indication specifies its corresponding suspend time interval, or comprises a code information referring to the corresponding suspend time interval.

Thereby, a comparatively high degree of flexibility in assigning and transmitting the information regarding the suspend time interval applicable for each different network slice and/or network service is possible to archive.

Alternatively, according to a further embodiment of the present invention, in a third step prior to the second step, a global suspend time information is transmitted, as part of the set of control channel data, to the user equipment, and the control of the second step is performed by means of a combined use of both the global suspend time information, and the plurality of specific suspend time indications.

Thereby, it is advantageously possible to base the determination of the suspend time interval on both information components, namely the global suspend time information, as well as the specific suspend time indications. It is thereby advantageously possible to reduce the data volume to be transmitted in order to transmit the information regarding the suspend time interval for each different network slice and/or network service.

According to the present invention, it is furthermore preferred that each one or at least one of the plurality of specific suspend time indications indicate, for the respective network slice, whether or not the global suspend time information is to be applied, resulting in the user equipment being restricted, for the respective network slice, from using user plane radio communication resources of the telecommunications network or from attempting to access the telecommunications network during a suspend time interval corresponding to the global suspend time information in case the corresponding specific suspend time indication for the respective network slice and/or different network services indicates so.

Thereby, it is advantageously possible, in essence, to define one applicable suspend time interval (by means of transmitting the global suspend time information), and to be able to decide (or indicate so by means of the transmission of the specific suspend time indications, corresponding, in its most basic manner, to the information of a single bit), for each different network slice and/or different network service, whether the one applicable suspend time shall apply (to the respective network slice and/or network service) or not.

According to a further preferred embodiment of the present invention, each one or at least one of the plurality of specific suspend time indications is or comprises a factor information to be applied for the respective network slice, resulting in the user equipment being restricted, for the respective network slice, from using user plane radio communication resources of the telecommunications network or from attempting to access the telecommunications network during a suspend time interval corresponding to the global suspend time information multiplied by a factor to be applied for the respective network slice, this factor being indicated by the factor information of the specific suspend time indication.

Thereby, it is advantageously possible not only use one single applicable suspend time interval (to be either applied (fully) or not at all) but to apply a different suspend time interval for each different network slice and/or different network service, but to transmit the corresponding information in an effective manner in order to save transmission resources.

According to still a further preferred embodiment of the present invention, each one of the plurality of specific suspend time indications is or comprises at least one out of the following:.

Hence, according to the present invention, the different possibilities of what the specific suspend time indications correspond to might also be mixed, i.e., for example, for a first network slice, the corresponding first specific suspend time indication corresponds to a bit value (indicating whether or not the suspend time interval (defined by means of the global suspend time information) shall be applied or not), and for a second network slice, the corresponding second specific suspend time indication corresponds to a factor information such that the suspend time interval is obtained by multiplying the time interval corresponding to the global suspend time information by a factor to be applied for the respective network slice, this factor being indicated by the factor information of the specific suspend time indication.

According to the present invention, it is furthermore preferred that the global suspend time information, on the one hand, and the plurality of specific suspend time indications, on the other hand, are transmitted.

According to the present invention, it is thereby advantageously possible to flexibly transmit the plurality of specific suspend time indications and also the global suspend time information.

According to still a further preferred embodiment of the present invention, the user equipment is - during the time interval corresponding to the suspend time interval - in a connected state, especially without an interruption of the radio resource control connection of the user equipment.

Thereby, it is advantageously possible that the radio resource control connection between the user equipment and the access network of the telecommunications network does not need to be re-established (after being shut down due to an overload situation within the telecommunications network). Hence 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 means of individually (i.e. on a per user equipment basis) allow or disallow the use of one or a plurality of specific network slices or network services (and another one or a plurality of other network slices or network services are still suspended (for a longer or shorter time interval) from being used by the user equipment.

Hence, according to the present invention, it is advantageously possible to avoid requiring a complete interruption of the radio resource control connection (by means of a general RRC connection release message) - just in order to being able to suspend the use (by one or a plurality of user equipments) of one or a plurality of network slices or network service. With regard to embodiments of the present invention such that the user equipment should not leave a connected state during the time interval corresponding to the suspend time interval (i.e. during this time interval, the RRC connection of the user equipment is maintained), the inventive method relates to controlling the use, by the user equipment, of user plane radio communication resources (and normally not to controlling the access of the user equipment to the telecommunications network - as this access is already provided by means of the existing RRC connection of the user equipment). Likewise, the plurality of specific suspend time indications (and, if applicable, the global suspend time information) are intended to relate to controlling the use, by the user equipment, of user plane radio communication resources (i.e. normally not to controlling the access of the user equipment to the telecommunications network).

However and also according to the present invention, it is not excluded that the radio resource control connection is indeed (completely) interrupted (or released) - in normal cases (i.e. overload control is, in such an implementation, performed such that RRC connections are indeed (mandatorily) released for such user equipments that are to be at least temporarily blocked) - between the user equipment and the telecommunications network (or its access network). In such a situation (of a complete interruption of the radio resource control connection of the user equipment), by means of:.

According to still a further preferred embodiment of the present invention, the use, by the user equipment, of user plane radio communication resources of the telecommunications network corresponds to the user equipment receiving payload data and/or user plane data from the telecommunications network and/or the user equipment transmitting payload data and/or user plane data to the telecommunications network.

Thereby, it is advantageously possible to apply the control of radio communication resources to user plane radio communication resources, i.e. to payload data and/or user plane data.

The present invention also relates to a system according to claim <NUM>.

Thereby, a system is provided to control the use of user plane radio communication resources of a telecommunications network and/or the access of a user equipment to the telecommunications network by imposing a suspend time interval to the user equipment (prior to be able to either use substantial data transmission resources of the telecommunications network, or prior to be able to again request access to the telecommunications network).

The present invention further relates to a user equipment according to claim <NUM>.

Thereby, a user equipment is provided by means of which the use of user plane radio communication resources of a telecommunications network and/or the access of the user equipment to the telecommunications network is able to be controlled by imposing, upon the user equipment, a suspend time interval to be elapsed prior to the user equipment being able to either use substantial data transmission resources of the telecommunications network, or prior to being able to again request access to the telecommunications network.

The present invention further relates to a telecommunications network according to claim <NUM>.

Thereby, a telecommunications network is provided to control the use of user plane radio communication resources of a telecommunications network and/or the access of a user equipment to the telecommunications network by imposing a suspend time interval to the user equipment (prior to be able to either use substantial data transmission resources of the telecommunications network, or prior to be able to again request access to the telecommunications network).

Additionally, it is preferred according to the present invention - with the inventive system as well with the inventive user equipment and telecommunications network - that a global suspend time information is transmitted, as part of the set of control channel data and by the telecommunications network, to the user equipment, or wherein a global suspend time information is received, as part of the set of control channel data, by the user equipment, and wherein the control is performed by means of a combined use of both the global suspend time information, and the plurality of specific suspend time indications.

It is thereby advantageously possible to archive a comparatively high degree of flexibility in assigning and transmitting the information regarding the suspend time interval applicable for each different network slice and/or network service.

Furthermore, the present invention relates to a program comprising a computer readable program code which, when executed on a computer or on a user equipment or on a network node of a telecommunications network, or in part on the user equipment and/or in part on the network node of the telecommunications network, causes the computer or the user equipment or the network node of the telecommunications network to perform a method according to the present invention.

Additionally, the present invention relates to a computer-readable medium comprising instructions which when executed on a computer or on a user equipment or on a network node of a telecommunications network, or in part on the user equipment and/or in part on the network node of the telecommunications network, causes the computer or the user equipment or the network node of the telecommunications network to perform a method according to the present invention.

It is to 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 of illustrated herein.

According to the present invention, an improved method for controlling, in a network slice-dependent (or network slice-specific) manner, the use of user plane radio communication resources of a telecommunications network and/or the access of a user equipment to a telecommunications network is disclosed. It is assumed according to the present invention that the telecommunications network <NUM> provides the use or activation of a plurality of different network slices <NUM>, <NUM>, <NUM> and/or of different network services.

In <FIG>, a user equipment <NUM> being connected to a telecommunications network <NUM> (or connected to a base station entity, such as, e.g., an eNodeB or gNodeB entity, as part of an access network of the telecommunications network <NUM>) is schematically shown. In a conventionally known manner, the telecommunications network <NUM> is a cellular mobile communication network, comprising an access network (not specifically shown) (and typically also a core network), and the access network typically comprising a plurality of base station entities, such as eNodeB and/or gNodeB base station entities, such base station entities serving radio cells, i.e. radio coverage areas of these base station entities, in a conventionally known manner.

Furthermore, in a conventionally known manner, at least within one radio cell or radio coverage area within or as part of the telecommunications network <NUM>, a set of control channel data is transmitted to the user equipment <NUM>.

As already mentioned, the user equipment <NUM> is able to use a plurality of different network slices <NUM>, <NUM>, <NUM> of or provided by the telecommunications network <NUM> (or it is able to use a plurality of different network services). In the exemplary representation of <FIG>, three network slices are schematically shown, namely a first network slice <NUM>, a second network slice <NUM>, and the third network slice <NUM>. According to the present invention, the only limitation in the number of network slices <NUM>, <NUM>, <NUM> is the possibility of the telecommunications network <NUM> to provide or manage (and, if applicable, of the user equipment <NUM> to handle) network slices <NUM>, <NUM>, <NUM>. A typical realistic number of network slices <NUM>, <NUM>, <NUM> to be, in principle, provided and/or activated by the telecommunications network <NUM> and/or by the user equipment <NUM> might be eight network slices, but an increased number of such network slices, such as nine, ten, eleven or twelve network slices are possible as well according to the present invention.

In <NUM> networks, network slicing allows customers to enjoy connectivity and data processing tailored to specific requirements (e.g. in line with a Service Level Agreement (SLA) agreed with an operator of the telecommunications network), the customizable network capabilities typically including one or a plurality out of the following: data speed, quality, latency, reliability, security, and services. From a mobile operator's point of view, a network slice is an independent end-to-end logical network that runs on a shared physical infrastructure, capable of providing a negotiated service quality. The technology enabling network slicing is transparent to customers of the network. A network slice could span across multiple parts of the network (e.g. terminal, access network, core network and transport network) and could also be deployed across multiple operators. A network slice comprises dedicated and/or shared resources, e.g. in terms of processing power, storage, and bandwidth and typically has the possibility of being isolated from the other network slices. Slice types could be defined from a functional or behavioral perspective. Mobile network operators are able to deploy a single network slice type that satisfies the needs of multiple verticals, as well as multiple network slices of different types that are packaged as a single product targeted towards business customers (a business bundle) who have multiple and diverse requirements (for example a vehicle may need simultaneously a high bandwidth slice for infotainment and an ultra-reliable slice for telemetry, assisted driving).

According to the method of the present invention, the use, by the user equipment <NUM>, of user plane radio communication resources of the telecommunications network <NUM> can be more efficiently controlled compared to the conventionally known methods. Especially in situations of network overload (or presumed or anticipated network overload) in a smaller or bigger part (or geographical region) of the telecommunications network <NUM> (e.g. involving one or a plurality of different radio cells of the telecommunications network <NUM>), a method is required to effectively reduce such network load, especially network load created by user equipments triggering or requesting user plane data transmission to and/or from the telecommunications network <NUM> (such user equipments <NUM> typically being located in the respective part or geographical region experiencing the network overload). According to embodiments of the present invention, the use of user plane radio communication resources of the telecommunications network <NUM> is controlled by imposing, to the user equipment <NUM>, a network slice-dependent (or network slice-specific) suspend time interval <NUM>, i.e. prior to the user equipment <NUM> being able to use substantial data transmission resources of the telecommunications network <NUM> (involving the use of a specific network slice and/or the use of a specific network service), the suspend time interval <NUM> (for that specific network slice and/or specific network service) needs to have elapsed.

For the enhanced and more efficient control of the use of user plane radio communication resources of the telecommunications network <NUM> according to the present invention, it is especially advantageous that the user equipment <NUM> stays - during the time interval corresponding to the suspend time interval <NUM> - in a connected state, especially without an interruption of the radio resource control connection of the user equipment <NUM>. Hence, as the imposition (or application) of the suspend time interval <NUM> does not necessarily require the radio resource control connection being shut down, the radio resource control connection between the user equipment <NUM> and the access network of the telecommunications network <NUM> does not need to be re-established, thus avoiding otherwise necessary overhead traffic and network as well as user equipment resources. Hence advantageously according to the present invention, an overload situation can still be handled by the telecommunications network <NUM> by means of individually (i.e. on a per user equipment basis) allow or disallow the use of one or a plurality of specific network slices <NUM>, <NUM>, <NUM> or network services (and another one or a plurality of other network slices or network services are still suspended (for a longer or shorter time interval) from being used by the user equipment <NUM>).

However, even though a (complete) release of the radio resource control connection between the user equipment <NUM> and the telecommunications network <NUM> occurs, it is possible according to the present invention to more efficiently control (compared to the conventionally known methods) the access of the user equipment <NUM> to the telecommunications network <NUM>. According to further embodiments of the present invention, the access of the user equipment <NUM> to the telecommunications network <NUM> is controlled by imposing, to the user equipment <NUM>, a network slice-dependent (or network slice-specific) suspend time interval <NUM>, i.e. prior to the user equipment <NUM> being able to access the telecommunications network <NUM> (involving the use of a specific network slice and/or the use of a specific network service), the suspend time interval <NUM> (for that specific network slice and/or specific network service) needs to have elapsed.

However, regarding all embodiment according to the present invention, the information regarding the suspend time interval <NUM> to be applied in a network slice-dependent manner, needs to be transmitted to the user equipment <NUM>. As part of the set of control channel data (not specifically shown), the user equipment <NUM> receives (i.e. the telecommunications network <NUM>, or, its access network, especially the respective base station entity, or gNodeB, transmits), in a first step of the inventive method, a plurality of specific suspend time indications <NUM>, <NUM>, wherein each one of the plurality of specific suspend time indications <NUM>, <NUM> relates to a different network slice <NUM>, <NUM>, <NUM> and/or to a different network service of the telecommunications network <NUM>, e.g. a first specific suspend time indication relating to a first network slice <NUM>, a second specific suspend time indication relating to a second network slice <NUM>, and a third specific suspend time indication relating to a third network slice <NUM>. This is schematically shown - for two exemplary scenarios - in <FIG>: In <FIG>, a first exemplary scenario of indicating a suspend time interval <NUM> by means of a global suspend time information <NUM> and a plurality of specific suspend time indications <NUM> is schematically shown, and in <FIG>, a second exemplary scenario of indicating a suspend time interval <NUM> by means of a global suspend time information <NUM> and a plurality of specific suspend time indications <NUM> is schematically shown.

According to the first exemplary scenario, represented in <FIG>, the specific suspend time indications <NUM> indicate, for the respective network slice <NUM>, <NUM>, <NUM>, whether or not the global suspend time information <NUM> is to be applied (i.e. the specific suspend time indications <NUM> correspond or comprise essentially a one-bit value), and the suspend time interval <NUM> for the respective network slice <NUM>, <NUM>, <NUM> corresponds to the global suspend time information <NUM> (indicating, e.g., a value of "<NUM> seconds") for such network slices <NUM>, <NUM>, <NUM> for which the corresponding specific suspend time indications <NUM> indicate that the global suspend time information <NUM> shall apply (in the exemplary scenario represented in <FIG>, this is the case for the first and second network slice <NUM>, <NUM> but not for the third network slice).

According to the second exemplary scenario, represented in <FIG>, the specific suspend time indications <NUM> are or comprise a factor information to be applied for the respective network slice <NUM>, <NUM>, <NUM>. As a result, the user equipment <NUM> is restricted, for the respective network slice <NUM>, <NUM>, <NUM>, from using user plane radio communication resources of the telecommunications network <NUM> during the suspend time interval <NUM>, and the suspend time interval corresponds to the global suspend time information <NUM> multiplied by a factor to be applied for the respective network slice <NUM>, <NUM>, <NUM>, this factor being indicated by the factor information of the specific suspend time indication <NUM>. In the exemplary scenario represented in <FIG>, the specific suspend time indication for the first network slice <NUM> indicates (by means of the corresponding factor information), e.g., a factor of <NUM>, hence resulting in a suspend time interval of <NUM> seconds based on (as in the first exemplary scenario) a global suspend time information <NUM> indicating, e.g., a value of <NUM> seconds. The specific suspend time indication for the second network slice <NUM> indicates, e.g., a factor of <NUM>, hence resulting in a suspend time interval of <NUM> seconds based again on a global suspend time information <NUM> indicating, e.g., a value of <NUM> seconds. The specific suspend time indication for the third network slice <NUM> indicates, e.g., a factor of <NUM>, hence resulting in a suspend time interval of <NUM> seconds based again on a global suspend time information <NUM> indicating, e.g., a value of <NUM> seconds.

Even though both <FIG> schematically represent exemplary embodiments involving the transmission of the global suspend time information <NUM>, such a global suspend time information is not necessarily required: According to other embodiments of the present invention (not specifically shown in the figures), the specific suspend time indications <NUM>, <NUM> comprise, respectively, an indication regarding the suspend time interval <NUM> to be applied to the respective network slice <NUM>, <NUM>, <NUM> or respective network service.

-- in a second step, subsequent to the first step, a control, related to the use of at least one of the plurality of different network slices (<NUM>, <NUM>, <NUM>) and/or the use of at least one of the different network services, of the use of user plane radio communication resources of the telecommunications network (<NUM>) is realized by deciding whether an attempt of the user equipment (<NUM>) to use user plane radio communication resources of the telecommunications network (<NUM>) is allowed or disallowed during a suspend time interval (<NUM>), wherein the user equipment (<NUM>) is - during the time interval corresponding to the suspend time interval (<NUM>) - in a connected state.
