- EN-DC In the deployments of EN-DC, not every LTE cell will be EN-DC capable (e.g., for reasons such as having old hardware, not having license, or no NR deployment in that area). This means that only some eNBs on some LTE frequency layers will be EN-DC capable. For example, an operator could have many EN-DC capable eNBs on low-band frequencies while no EN-DC capable eNBs on mid/high- band.
- the main task of a mobile radio network is to provide good radio connections for mobile devices to carry the services the users of the mobile want to utilize. In this process it its central to find the most suitable cells or antenna beams for every mobile as it moves around. This is today performed by requesting the mobile to measure strength and quality of radio signals from the serving beams as well from neighbor beams. The results of the measurements are reported to the RAN, which takes a decision on what cells shall serve the mobile in the following. Measurements on the target cell can require information about possibility of NR access. For example, EN- DC band combination possibility on the target LTE cell which require NR layer information. Further, this information is required for measuring NR coverage. For example, FIG. 5 illustrates a mobile device that is simultaneously using both LTE and NR, moving into a new LTE cell.
- Mobile device is here used as the term for the equipment terminating the wireless connection from the base station. It need not be moving but can be stationary and can also be referred to as e.g. Station, Mobile Station or User Equipment.
- the information can include identities, frequency and bandwidth of the cell, as well as the neighbor cells of the served cell.
- the information can be used in the decision where to move a mobile that is reaching the border of a serving cell or ends its connection.
- the bandwidth can be vital for certain services and a mobile with such a service can only be moved to a cell with enough bandwidth.
- FIG. 6 illustrates an example procedure for exchange of served cell and neighbor cell information.
- Network Sharing Network Sharing is a method of sharing some portions of network architecture among multiple parties. This is done mostly to save the cost or critical locations.

- SIB system information block 1
- an eNB (or other base station) can report the dual connectivity (e.g., EN-DC) capability of its cells and their NR (or other RAT) neighbors, to its neighbor eNBs. This is used for EN-DC aware traffic steering.
- EN-DC dual connectivity
- a goals of EN-DC aware traffic steering can be either to (1) move UEs from an LTE layer where they cannot run EN-DC (reasons could be eNB having an old hardware, lack of license, not supported 3GPP band combinations for EN-DC, not supported UE band combinations for EN-DC, etc.) to an LTE layer where they can run EN-DC; (2) move UEs from an LTE layer where they can run EN-DC to another LTE layer where they can run EN-DC, but get a better service (usually throughput, e.g., by enabling access to NR high band).
- a shared RAN scenario e.g., multiple PLMNs using a single cell
- dual connectivity e.g., EN-DC
- EN-DC dual connectivity
- FIG. 7 An example is illustrated in FIG. 7, where eNBl belongs to operator 1 and does not provide EN-DC.
- eNB2 belongs to operator 2 and does not provide EN-DC either.
- eNB3 is using shared RAN and has an LTE cell that belongs to both operator 1 and operator 2. But it is only the UEs with subscription from operator 2 that can run EN-DC with the NR layer, because the gNB in that area belongs to operator 2 (or some other operator that has only EN-DC contract with operator 2).
- eNBl will only know that the cell on eNB3 is EN-DC capable and will not know which operators (or PLMNs) can run EN-DC and which operators cannot. So, it will not be able to distinguish between the cell on eNB3 and another EN-DC capable cell that only belongs to operator 1.
- the techniques describe herein can allow for enhanced dual connectivity-aware (e.g., EN-DC-aware) traffic steering that takes into account dual connectivity feature availability on a per-service identifier basis for cells that include multiple service identifiers (e.g., PLMN IDs).
- dual connectivity-aware e.g., EN-DC-aware
- PLMN IDs multiple service identifiers
- this can be achieved by mapping the dual connectivity (e.g., EN-DC) capability of a cell (e.g., an LTE cell) to a service identifier (e.g., PLMN) for a particular service (e.g., operator) available through that cell, where one base station (e.g., eNB associated with the cell) tells its neighbor base stations (e.g., other eNBs), for each of its own cells, a list of service identifiers (e.g., PLMN IDs) that the cell is allowed to use for dual connectivity (e.g., EN-DC).
- a service identifier e.g., PLMN
- PLMN IDs e.g., PLMN IDs
- FIG. 8A An example is illustrated in FIG. 8A, where gNB 1 belongs to operator 1 and does not provide NE-DC. Similarly, gNB2 belongs to operator 2 and does not provide NE-DC either. But gNB3 is using shared RAN and has an NR cell that belongs to both operator 1 and operator 2. But it is only the UEs with subscription from operator 2 that can run NE-DC with the NR layer, because the eNB in that area belongs to operator 2 (or some other operator that has only NE-DC contract with operator 2). Now, from an NE-DC traffic steering point of view, gNBl will only know that the cell on gNB3 is NE-DC capable and will not know which operators (or PLMNs) can run NE-DC and which operators cannot.
- FIG. 8B Another example is illustrated in FIG. 8B, where eNB3 belongs to operator 2 and does not provide EN-DC. Similarly, eNB2 belongs to operator 1 and can only provide EN-DC with NR layer configured on gNB 1. But eNB 1 , on the other hand, is using shared RAN and has an LTE cell that belongs to both operator 1 and operator 2. But it is only the UEs with subscription from operator 2 that can run EN-DC with the NR layer, because the gNB2 in that area belongs to operator 2 (or some other operator that has only EN-DC contract with operator 2).
- eNB3 will only know that the cell on eNB 1 is EN-DC capable and will not know which operators (or PLMNs) have NR layer configured and which operators do not have. So, it will not be able to distinguish between the cell on eNB3 and another EN-DC capable cell that only belongs to operator 1 where UE can run EN-DC.
- an eNB may need information about the supported EN-DC band combination, combination of LTE and NR bands, for the UE where information regarding configured NR layer (NR cell) on each eNB is necessary. Without this information, an eNB might not properly decide the best EN-DC capable cell for EN-DC traffic steering.
- EN-DC UEs For example, otherwise it might decide to either steer all EN-DC UEs to the EN-DC capable cell(s) or steer none of them.
- the first option will result in unnecessary traffic steering of EN-DC UEs where UE cannot run EN-DC and access NR leg, and further overloading the EN-DC layer on eNB 1.
- the second option will result in EN-DC UEs on eNB2 to stay there and not being able to run EN-DC at all and access NR.
- FIG. 1 shows a wireless communication network 10 according to some embodiments.
- the network 10 as shown includes radio network nodes 12A and 12B (e.g., in the form of base stations).
- the radio network nodes 12A and 12B may be included in a radio access network (RAN) portion of the network 10, which may in turn connect to a core network (CN) portion (not shown).
- RAN radio access network
- CN core network
- Each radio network node 12A, 12B serves one or more cells. As shown, for example, radio network node 12A serves N cells 14A-1,... 14A-N, for N A 1. and radio network node 12B serves M cells 14B-1,... 14B-M, for M A 1 Different cells may for instance be provided on different carrier frequencies, with different frequency bandwidths, and/or using different radio access technologies.
- radio network node 12B is configured to transmit control signalling 16 to radio network node 12 A, e.g., directly over an interface (e.g., X2AP) established between the radio network nodes 12A, 12B or indirectly via one or more intermediate nodes (e.g., in the CN portion of the network 10).
- Radio network node 12A correspondingly receives this control signalling 16.
- the control signalling 16 indicates whether radio network node 12B, or a cell served by radio network node 12B, supports so-called multi-connectivity.
- Multi-connectivity in this regard refers to the simultaneous connection of a wireless device 18 (e.g., at a radio resource control, RRC, layer) to multiple different radio network nodes, or to multiple different cells served by different radio network nodes.
- the multiple different radio network nodes or cells may use the same radio access technology (e.g., both may use Evolved Universal Terrestrial Radio Access (E- UTRA) or both may use New Radio (NR)).
- E- UTRA Evolved Universal Terrestrial Radio Access
- NR New Radio
- the multiple different radio network nodes or cells may use different radio access technologies, e.g., one may use E-UTRA and another may use NR.
- multi-connectivity is dual connectivity (DC) in which the wireless device 18 is simultaneously connected to two different radio network nodes, or to two different cells served by two different radio network nodes.
- the wireless device 18 may be configured with a so-called master cell group (MCG) and a secondary cell group (SCG), where the MCG includes one or more cells served by the radio network node acting as a master node and the SCG includes one or more cells served by the radio network node acting as a secondary node.
- MCG master cell group
- SCG secondary cell group
- the master node may be a master in the sense that it controls the secondary node.
- E-UTRA-NR (EN) DC refers to where the master node uses E-UTRA and the secondary node uses NR
- NR-E-UTRA (NE) refers to where the master node uses NR and the secondary node uses E-UTRA.
- a cell supports multi -connectivity if the cell is able to be included in a MCG or SCG provided by a radio network node that supports multi-connectivity.
- a radio network node supports multi-connectivity if the radio network node supports a wireless device connecting to the radio network node while the wireless device is also connected to another radio network node and/or if the radio network node is capable of acting as a master node or a secondary node.
- control signalling 16 indicates whether radio network node 12B supports multi -connectivity
- the control signalling 16 may indicate if the radio network node 12B supports wireless device 18 connecting to the radio network node 12B while the wireless device 18 is also connected to another radio network node.
- control signalling 16 indicates whether a cell served by radio network node 12B supports multi-connectivity
- the control signalling 16 may indicate if the cell is able to be included in a MCG or SCG provided by radio network node 12B.
- the radio network node 12 may accommodate scenarios in which the radio network node 12 serves one or more cells that support multi-connectivity but also serves one or more cells that do not support multi -connectivity, e.g., because the cells rely on old hardware, do not have the requisite license, or do not have a need for the support due to not neighboring another cell.
- the control signalling 16 may indicate which cells 14B-1,... 14B-M served by radio network node 12B, if any, support multi-connectivity. Signalling multi-connectivity support on such a cell by cell basis may prove advantageous for discriminating between the cells on the basis of multi-connectivity support in the context of certain procedures, such as mobility procedures.

- An LTE cell can have more than one PLMN ID and can have one or more NR cells (e.g., neighboring) deployed for (e.g., sharing) each corresponding PLMN. This will usually mean that the cell allows the connection and access of UEs from two or more operators, but potentially one operator could also use different PLMN IDs to distinguish different services. It can happen that the cell can only provide EN-DC to the UEs having one (or more) of the PLMNs and cannot provide EN-DC to UEs having other supported PLMNs on this cell.

Abstract
La présente invention concerne des procédés, des systèmes et des dispositifs ayant trait à la signalisation de commande relative à la prise en charge de connectivité multiple. Selon certains modes de réalisation, un nœud de réseau radio reçoit une signalisation de commande indiquant si chaque identifiant de service d'un autre nœud de réseau radio ou chaque identifiant de service d'une cellule desservie par l'autre nœud de réseau radio prend en charge une connectivité multiple. Selon certains modes de réalisation, un nœud de réseau radio transmet une signalisation de commande indiquant si chaque identifiant de service du nœud de réseau radio ou chaque identifiant de service d'une cellule desservie par le nœud de réseau radio prend en charge une connectivité multiple.
