Systems, methods, apparatuses, and computer-program products for performing carrier aggregation across different radio access technologies are disclosed. For example, in some instances a method of wireless communication includes transmitting, using a first wireless communication device, control information to a second wireless communication device via a first radio access technology (RAT), the control information including control information for a second RAT; and receiving, at the first wireless communication device, an acknowledgement (ACK) or negative acknowledgement (NACK) from the second wireless communication device via the first RAT, the ACK or NACK being related to communications of the second wireless communication device conducted via the second RAT.

A communication device for handling a user equipment (UE) Access Stratum (AS) context comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving a first radio resource control (RRC) message via a RRC connection from a first radio access network (RAN) of a first radio access technology (RAT), wherein the RRC message comprises a resume identity and indicates a RRC suspension; suspending the RRC connection in response to the first RRC message; keeping a UE AS context, when the RRC connection is suspended; selecting a cell of a second RAN of a second RAT different from the first RAT; and determining that the UE AS context and the resume identity are invalid in response to the selection.

Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A 5G-capable wireless device of an MNO, while connected to or camped on a legacy 4G LTE cell of the MNO and not engaged in a 4G only LTE service, determines whether an NSA 5G cell of another MNO satisfies performance criteria before measuring and/or sending measurement data for an NSA 4G LTE anchor cell associated with the NSA 5G cell to a wireless network. Refraining from measuring and/or sending measurement data under certain conditions causes the 5G-capable wireless device of the MNO to remain connected to or camped on the legacy 4G LTE cell of the MNO rather than reselecting or handing over to the NSA 4G LTE cell of another MNO. The 5G-capable wireless device also maintains a database of information for valid NSA 4G LTE cells to which to reselect/handover.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a mobile communication system is provided according to one embodiment of the present disclosure. The method comprises the steps of: transmitting a first message, comprising network function information of the terminal, to a mobility management entity associated with a first network; if the network function information instructs support for a second network, receiving a second message comprising connection reactivation request information from the mobility management entity; releasing the connection with respect to the first network in response to the second message; transmitting a third message, for reestablishing connection to the first network, to the mobility management entity on the basis of the connection reactivation request information. The third message comprises an identifier of a first session for the second network corresponding to the connection with respect to the first network allocated by the terminal.

Techniques that facilitate mobile device self-optimizing technology selection thresholds for a wireless communication system are provided. In one example, a method comprises: generating, at a first time, first information in a repository of information specific to and stored at the apparatus, wherein the first information comprises an identifier for a first access point device and a determined acceptable signal strength usable to obtain an acceptable jitter value between the apparatus and the first access point device; and initiating a defined type of communication via the first access point device, at a second time, based on a first determination that a detected signal strength at a third time satisfies a defined condition relative to the acceptable signal strength, wherein the second time is after the first time and wherein the third time is between the first time and the second time.

A wireless device, a network node and methods therein are provided for achieving a seamless transition of a streaming session from enhanced Multimedia Broadcast Multicast Service (eMBMS) in a source cell or area, to unicast in a target cell or area. The method to be performed by a wireless device engaged in a streaming session via eMBMS comprises obtaining an URL of a streaming server providing data for the streaming session from a first network node providing the eMBMS. The method further comprises detecting that a signal quality related to the eMBMS falls below a threshold; and further providing the obtained URL to a second network node in order to induce the second network node to prepare for unicast of the streaming session via a target node. The method further comprises connecting to the target node for continuation of the streaming session.

The teachings relates to method (40) in a target network (node16) of a target core network in a first domain during handover, in the first and in a second domain, of a communication device (20) from a source radio access network to a target radio access network. The source radio access network comprises a source access node (11) and the target radio access network comprises a target access (node12). The method (40) comprises determining (41) whether the communication device (20) has access admission to the target core network; when a hand over fails generating (42) a hand over failure message comprising an information element Independent domain HandOver, where in the information element is set to a predefined value indicating whether the hand over failed due to lack of access rights or for other reasons than lack of access rights. The teachings also relates to devices and further to methods in source nodes.

A computer device may include a memory configured to store instructions and a processor configured to execute the instructions to determine a service requirement for a client device connected to a WiFi access point in a customer premises network that includes a plurality of WiFi access points. The processor may be further configured to monitor a service requirement parameter, associated with the determined service requirement, for the client device; detect that the service requirement parameter is within a threshold of the determined service requirement; and perform a self-organizing network (SON) action on the customer premises network, in response to detecting that the service requirement parameter is within the threshold of the determined service requirement.

Systems and methods according to these exemplary embodiments provide for improving communications systems which use home gateways or the like. This can be obtained by avoiding potentially frequent inter-MME (intra-MME pool) context transfers. This can then reduce unnecessary or redundant signalling.

Switching the providing of a conversation among communication links is described. An electronic device can determine that a mobile device is being used to provide a conversation (e.g., a phone call) using a first communication link. The mobile device can enter an environment that includes a second communication link. The conversation can be switched to the second communication link that provides more content than the first communication link (e.g., audio and visual content rather than just audio content).
