A system information transmission method is provided. The system information transmission method includes the following steps. A first preamble for system information request is transmitted by a UE to a base station. When an acknowledgement message from the base station is not received, the first preamble for system information request is retransmitted by the UE to the base station. When the acknowledgement message from the base station is received, system information is received by the UE from the base station.

A state transition method of a wireless communication system is provided. A network transition request is transmitted by a wireless electronic device to a first base station of a first network. The network transition request includes an assistance information of the wireless communication device. A handover request including the assistance information is transmitted by the first base station to a second base station of a second network. A handover message is generated and transmitted by the second base station to the first base station in response to the handover request. A state transition message is generated and transmitted by the first base station to the wireless communication device in response to the handover message. The wireless communication device transitions from an RRC inactive state of the first network to a first state of the second network in response to the state transition message.

A wireless electronic device is provided. The wireless electronic device in a wireless communication system has a first data transmission path with a core network. The wireless electronic device includes a processor configured to perform the following instructions. A second data transmission path with a second wireless electronic device, coupled to the core network, is established. An access stratum module of the wireless electronic device is deactivated after the wireless electronic device receives a release request from the core network via the first data transmission path. The AS module is activated when a mobile data is generated by the wireless electronic device. The first data transmission path with the core network is established in response to context information received from the second wireless electronic device via the second data transmission path. The mobile data is transmitted to the second wireless electronic device via the second data transmission path.

Group paging methods and wireless communication devices and base stations using the same methods are proposed. In some embodiments, group identifiers are partitioned into different pools and assigned to wireless communication devices based on their mobility. When a base station intends to perform group paging, specific devices, not responded to the previous group paging, will be paged, or the group paging is repeated, and the other devices which responded to the previous group paging ignore the repeated group paging in a period of time. In other embodiments, a device responds to the group paging at the opportunity of random access process based on the indicator given in its idle information or the indicator given in paging message with some pre-determined mathematical operation or the pre-determined mathematical calculations on its device identity.

摘要:
A method for scheduling one or more handover measurements to be performed by a user terminal in a communications system using a plurality of radio access technologies (RATs), wherein the user terminal is in communication with a serving network interface device and is in the neighborhood of one or more neighboring network interface devices. The method includes gathering timing information of the one or more neighboring network interface devices, and determining at least one scanning interval using the timing information of the one or more neighboring network interface devices, the at least one scanning interval being a time period during which the user terminal performs the one or more handover measurements by measuring signals of the one or more neighboring network interface devices.
摘要:
In this invention, a novel vertical handover control algorithm, consisting of a throughput-based mapping function, QoS-based dynamic handover thresholds, and performance-based trigger timers, are proposed to resolve uncommon pilot problem, QoS requirements, and ping-pong effects, respectively. An analytic model based on a finite state machine is developed to evaluate the proposed algorithm in terms of the handover frequency and achievable throughput. A numerical analysis is also provided to further quantify the performance impacts.
