The inter-system ping-pong suppression method, an apparatus, a terminal device and a storage medium are provided. The method comprises: determining a target network standard in at least two network standards when the terminal device is in inter-system ping-pong state, wherein the inter-system ping-pong state refers to a state that the terminal device repeatedly switches between cells of at least two network standards; closing the network capability of the terminal device in other network standards, wherein the other network standards are the network standards other than the target network standard among at least two network standards.

Secure, distributed radio access networks are enabled, e.g., to facilitate network resilience and security. For instance, a device can comprise a processor, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: in response an event being determined to have occurred that affects operation of a primary radio access network, activating an alternate radio access network via a group of mobile devices and re-routing communications from being communicated via a fixed location radio access network equipment of the primary radio access network to being communicated via the group of mobile devices of the alternate radio access network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

A method for handling the joining and leaving an MBS session via a PDU session establishment or modification procedure is provided. Upon receipt of a back-off timer in the Received MBS Container IE (with the operation/decision “MBS join is rejected” or “Remove UE from the MBS session”), the UE shall associate the MBS back-off timer with the MBS session ID (e.g., TMGI). If the timer value is neither zero nor deactivated, the UE should not request to join the MBS session with the same MBS session ID before the timer expiry. If the timer value is deactivated, the UE should not request to join the MBS session with the same MBS session ID until the UE is switched off, the USIM is removed, an entry in the “list of subscriber data” for the current SNPN is updated, or an event/notification is triggered by the network.

Embodiments include methods for a target node to establish a connection with a user equipment (UE) operating in dual connectivity (DC) with a PCell utilizing a first radio access technology (RAT) and with a PSCell utilizing a second RAT. Embodiments include receiving, from the UE, a re-establishment request message comprising parameters associated with the PSCell, a first message authentication code (MAC), and an indication of the UE's selection of a target cell served by the target node as a replacement for the PCell. The target cell utilizes the second RAT. Embodiments include verifying the message integrity based on the first MAC, and determining a full UE context based on the plurality of parameters associated with the PSCell and on a successful verification of the message integrity. Embodiments include establishing a connection with the UE based on the full UE context, whereby the target cell serves as a PCell for DC.
