Control of communication using dual-connectivity mode description

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 an indication from a target communication network control element, wherein the indication indicates whether or not a multi-connectivity mode of a communication element making a reestablishment request at the target communication network control element is kept, and
• to determine, on the basis of the indication, whether the multi-connectivity mode of the communication element is to be kept under the target communication network control element.

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 an information from a source communication network control element about a communication connection reestablishment attempt of a communication element communicating in a multi-connectivity mode, and
• to recognize from the information that the multi-connectivity mode of the communication element is to be kept,
• wherein a resource management is optimized on the basis of the information that the multi-connectivity mode of the communication element is kept.
