Apparatuses, methods, and systems are disclosed for voice session handover. One method (800) includes receiving (802) a handover message including first information indicating a voice handover request to handover a voice session from a first network to a second network. The method (800) includes determining (804) a first network function configured to facilitate communication with the second network. The method (800) includes transmitting (806) a relocation request message to the first network function, wherein the relocation request message includes second information related to the voice handover request. The method (800) includes receiving (808) a relocation response message from the first network function, wherein the relocation response message indicates completion of a voice handover. The method (800) includes transmitting (810) third information related to the voice handover to a third network function, wherein the third network function suspends non-guaranteed bit rate data flows.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may connect to a set of source cell groups (CGs). The UE may receive a target cell group setup information, the target cell group setup information being associated with a set of target CGs. The UE may connect to the set of target CGs based at least in part on the target cell group setup information during a handover from the set of source CGs to the set of target CGs. The UE may disconnect from the set of source CGs after connecting to the set of target CGs. Numerous other aspects are provided.

A system and method for power headroom reporting (PHR) during a Dual Activity Protocol Structure (DAPS) handover procedure. The system and method include receiving, by a wireless communication device, a handover command to begin a dual activity protocol structure (DAPS) handover; detecting, by the wireless communication device during the DAPS handover, a condition for power headroom reporting (PHR); and performing, by the wireless communication device during the DAPS handover, the PHR.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure a bandwidth part (BWP) switching configuration of a user equipment in connection with a dual active protocol stack (DAPS) handover based at least in part on a BWP switching rule; and perform the DAPS handover. Numerous other aspects are provided.

A service data transmission method and apparatus, a terminal device, and a network device are provided. The method performed by a second terminal includes: receiving a transfer indication sent by a network device; and receiving, according to the transfer indication, target service data sent by a target network function, where the target network function is a network function sending service data to a first terminal.

Embodiments enable seamless Wi-Fi roaming by providing a user with a single username that is associated with a set of resources in the seamless network that includes different Wi-Fi networks (e.g., Wi-Fi networks with different domain names). As a user travels from a first access point in a first Wi-Fi network to a second access point in a second Wi-Fi network within the seamless network, network elements in the seamless network may recognize the user's single username as an already established session (e.g., with the first access point) and direct traffic accordingly to the second access point. Embodiments also satisfy business requirements by updating accounting data accordingly by indicating that the user accessed the seamless network from the first Wi-Fi network. Embodiments allow a user roaming on the seamless network to experience the policies and network requirements associated with the Wi-Fi domain of the second access point.
