    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: Methods and apparatus management of dual connectivity in wireless communications. A master base station belonging to a wireless communication network including the master base station and a secondary cell group including at least one secondary base station, configures one or more secondary cell group bearers for a secondary base station. Configuring the secondary cell group bearer includes configuring an inactivity timer for the secondary cell group. The inactivity timer is configured to indicate that, if no activity has occurred on the secondary cell group bearer during pendency of the inactivity timer, the secondary cell group bearer is to be released. The master base station then signals the configuration to the secondary base station.

    Abstract: An apparatus including 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.

    Abstract: Certain embodiments of the invention generally relate to mobile communications networks. For example, some embodiments relate to secondary cell group change procedure(s) for dual connectivity. A method may include receiving, at a network node, a secondary network node modification required message comprising secondary cell group configuration information for one or more secondary cell group data radio bearer type changes. The method may also include deciding to reject at least one of the one or more secondary cell group data radio bearer type changes. The method may further include sending a secondary network node modification request comprising an indication that the at least one secondary cell group data radio bearer type change is rejected by the network node, and that release of at least one or more secondary cell group data radio bearers is to be performed.
