Abstract: embodiments herein relate, for example, to a method performed by a network node () for handling registering to an internet protocol multimedia subsystem, ims, network in a communication network. the network node, with the proviso that a user equipment, ue, () is performing a handover from a first public land mobile network, plmn, of a first country or operator to a second plmn of a second country or operator, performs one or more of the following: —enforcing the ue () to make a session initiation protocol, sip, registration whereby an ims system can switch off sip encryption policy, immediately after having entered the second plmn; —initiating a sip re-invite with a session description protocol, sdp, including a ue subscriber identity, id, a remote party id, and an indication of a speech codec; and 7 or —when the network node knows by configuration that the second plmn requires a different sip encryption policy than currently used, sending a message to another network node, wherein the message indicates explicitly or implicitly that a different sip encryption policy and/or li policy is to be used.

Abstract: methods and systems are provided for nes (network energy savings) operations in a network. a network node may transmit to user equipments (ues) an indication about an nes operation activation for one or more cells. the ue(s) may send a reconfiguration request to modify the nes operation for one or more cells, for example to avoid a degradation in service that may negatively impact key performance indicators or quality of experience. in response, the network node may modify the nes operation. the network node may then send an updated indication about the modified nes operation for the one or more cells.

Abstract: techniques are described for mitigating the negative effects of temporary loss of connectivity or temporary loss of service between a ru and a bu. in embodiments of the present disclosure, the radio unit is configured to transmit reference signals during a temporary loss of connectivity with the baseband unit to allow the ues served by the radio unit to maintain synchronization with the radio unit and avoid or minimize radio link failures. applying these techniques, the ues served by the radio unit can maintain connection with the radio unit during the temporary outage and avoid the need to engage in radio resource control (rrc) signaling to re-establish a connection with the radio unit and/or handover to neighboring radio units.
