Abstract: There are provided measures for enabling/realizing more efficient radio link problem handling in a mobile communication system. Such measures exemplarily comprise detecting a radio problem of a radio link carrying a network connection of a communication device, and initiating a recovery procedure for recovering the connection on said radio link and a re-establishment procedure for re-establishing the connection on an alternative radio link, upon detection of the radio link problem, before a radio link failure of said radio link is declared.

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: A method and apparatus may include receiving, by a user equipment from a first access point which supports a first radio access technology, a radio-resource-control (RRC) reconfiguration message including an RRC configuration information of a second access point, after an initiation of a slave RRC at the second access point has been determined. The second access point supports a second radio access technology, and performing, by the user equipment, a random access procedure with the second access point based on the RRC reconfiguration message. The user equipment is configured to have an RRC connection with the first access point and the first access point is a master node.
