Abstract: Various communication systems may benefit from appropriate restriction on use. For example, certain wireless communication systems may benefit from radio-access-technology-specific access restrictions. A method can include registering a user equipment with a network element. The registering can include identifying user equipment capabilities. The method can also include receiving a response from the network element indicating restriction on use of at least one radio access technology.

Abstract: Systems, methods, apparatuses, and computer program products for partial failure handling of bearer mapping in dual connectivity are provided. One method includes, during a secondary evolved node B (SeNB) addition procedure, providing a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB. The method may further include receiving, by a master evolved node B (MeNB), bearer mapping for failed bearers from the target SeNB, and providing the source SeNB with the bearer mapping for the failed bearers.

Abstract: There is provided updating neighboring cell information for a secondary radio access node controlled by a master radio access node. Neighboring cells are measured by user equipment served by the master radio access node and the secondary access node controlled by the master radio access node. Neighboring cell information is obtained. Neighboring cell information maintained in at least the secondary radio access node is updated on the basis of the obtained neighboring cell information.

Abstract: The present invention provides an apparatus and method for control of communication using dual-connectivity mode, and the apparatus includes at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry cause the apparatus at least: to receive and process a communication connection reestablishment request from a communication element communicating in a multi-connectivity mode, to decide, in case a communication connection with the communication element is established, whether or not the multi-connectivity mode of the communication element is kept, and to cause a transmission of an indication towards a source communication network control element of the communication element, wherein the indication reflects the decision whether or not the multi-connectivity mode of the communication element is kept. The present invention can improve the dual connectivity performance, and a potential signaling overhead over network interfaces in case of a reconfiguration failure happening can be reduced.

Abstract: Transport information of a second communication system is allocated to at least one radio access bearer between a terminal device and a first packet core serving device of a first communication system. Information about the at least one allocated tunnel endpoint is signalled to a network access device of the first communication system, and data received from the first packet core serving device of the first communication system at one of the at least one allocated tunnel endpoints and data received from a second packet core serving device of the second communication system is forwarded to the terminal device during an inter-system handover.
