    Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform at least receiving, by a network device of a communication network, information providing an indication to connect to a network node of the communication network using a Random Access Channel (RACH)-less) signaling procedure; determining that connecting to the network node using the RACH-less signaling procedure has failed; and based on the RACH-less signaling procedure failing, using at least one alternative signaling procedure for connecting to the network node using uplink (UL) resources from RACH-less procedure. Further, in accordance with example embodiments of the invention there is at least a method and apparatus to perform based on a RACH-less signaling procedure from a network device failing to connect to a network node, receiving, by the network node, at least one alternative signaling procedure from the network device for the connecting; and establishing a connection with the network device based on the at least one alternative signaling procedure from the network device using the UL resources from RACH-less procedure.

    Abstract: There are provided measures for measurement relaxation change based on the total received power, in particular on an indicator of the total received power. Such measures exemplarily include, at a terminal in a radio resource management measurements relaxation mode having a reduced radio resource management measurements activity within a first relaxation mode scope as a relaxation mode scope of said radio resource management measurements relaxation mode, the terminal being served by a radio cell in a frequency band, achieving information on a parameter indicative of a total power received by said terminal at said frequency band, and deciding on a change of said relaxation mode scope of said radio resource management measurements relaxation mode based on said information on said parameter indicative of said total power received by said terminal at said frequency band.

    Abstract: Apparatus and method to perform receiving from a network node of a first mobile network of more than one mobile network of a communication network, by a user equipment of the first mobile network, an indication (610) of an approaching coverage limit for a coverage area associated with a link between the first public land mobile network and the user equipment wherein the user equipment includes a multi subscriber identity module, and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first mobile network; and based on the receiving, performing pro-active preparation for causing (620) a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation of switching to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area. Further, there is determining, by a network node of a first mobile network of more than one mobile network of a communication network, an approaching coverage limit for a coverage area associated with a link between the first mobile network and a user equipment, wherein the user equipment includes a multi subscriber identity module and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first public land mobile network; and based on determining, sending towards the user equipment information including an indication to perform pro-active preparation for causing a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation for switching by the second subscriber identity module to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area.
