Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement push-to-talk type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

A DRX control method and system includes receiving, from a source base station for transferring the UE from the source base station to a target base station, a plurality of configurations including: a first configuration of a first Discontinuous Reception (DRX) cycle, a second configuration of a second DRX cycle, and a first timer counting a period in the first DRX cycle to shift from the first DRX cycle to the second DRX cycle; performing, in a state of RRC Radio Resource Control (RRC) connected with the target base station, DRX operation with the first DRX cycle; and performing, in a state of RRC connected with the target base station, the DRX operation with the second DRX cycle when the UE does not receive data from the target base station until the first timer expires in the first DRX cycle.

Systems, methods, and processing nodes are configured to manage data throughput of wireless devices in a wireless network, such as a network that employs MIMO techniques, by receiving a request from a wireless device to operate in the wireless network using a first communication protocol, the wireless network deploying communications with wireless devices using at least two communication protocols simultaneously determining that a value associated with data rate used by a set of wireless devices in the wireless network using at least one of the at least two communication protocols exceeds a threshold value, and adjusting an operating parameter of a multi-element antenna for communicating signals between an access node and the plurality of wireless devices in the wireless network using the first communication protocol when it is determined that the value exceed the threshold value.

Systems, methods, and computer-readable media are provided for optimizing user plane node selection process during a process of handing over user equipment between two communication networks. In one aspect, a method includes receiving, at a network component, a session creation request for handing over the user equipment, the user equipment having a current active communication session within a first communication network with a first node of the first communication network, the session creation request including an identifier of the first node; receiving, at the network component, a list of candidates to serve as a user plane serving gateway for the user equipment in the second communication network; and selecting, by the network component and based on at least the identifier of the first node, the first node from the list of candidates to serve as the user plane serving gateway for the user equipment in the second communication network.

A wireless device may include a digital receiver and a digital transmitter, and a controller configured to control the digital receiver to receive signals and the digital transmitter to transmit signals, and further configured to receive a registration rejection from a first roaming mobile network while roaming, add the first roaming mobile network to a list of forbidden mobile networks, register with a second roaming mobile network and receiving an operator list of mobile networks from a home mobile network, and attempt to register with the first roaming mobile network based on a ranking of mobile networks in the operator list.

A handover method, a network device, and a terminal device are provided. The method includes: a first network device acquires measurement results of links, wherein the links include a link between the first network device and a first terminal device and a link between the first network device and a second terminal device; and the first network device determines at least one of a first handover scheme of the first terminal device, or a second handover scheme of the second terminal device according to the measurement results.

Certain aspects relate to methods and apparatus for discovering whether one or more enhanced capabilities are supported by devices (e.g., user equipment (UE), base station (BS), etc.) in a network. The enhanced capabilities may include, for example, the ability to support certain low latency procedures, enhanced component carrier (eCC) capability, and the like. The devices in the network may perform one or more handover-related procedures (e.g., cell selection/reselection, make-before-break handover, etc.) and/or other procedures (e.g., QoS negotiation, etc.) based, at least in part, on support for the one or more enhanced capabilities.

Aspects of the disclosure provide a processing circuit in an electronic apparatus and a method to switch the electronic apparatus during an inter-system handover (HO) process from a source network system to a target network system. The processing circuit can include an inter-system HO signal processing module and a mapping module. The inter-system HO signal processing module can be configured to obtain a mapping relationship between a set of source bearers associated with the source network system and a first set of target bearers associated with the target network system based on quality of service (QoS) characteristics associated with the set of source bearers and the first set of target bearers. The mapping module can be configured to obtain a second set of target bearers based on resources allocated to the first set of target bearers by the target network system and to obtain a third set of target bearers that is based on the first and second set of target bearers.
