Embodiment Construction

[0018] figure 1 It is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention. The wireless communication system 10 can be briefly composed of a network terminal and a plurality of communication devices. exist figure 1 In , the network terminal and multiple communication devices are used to illustrate the architecture of the wireless communication system 10 . According to device-to-cellular (D2C) communication (ie, device-to-network communication) defined in a communication standard (such as the 3rd Generation Partnership Project (3GPP) standard), a communication device Can communicate with the network side. In fact, in the Universal Mobile Telecommunications System (UMTS), the network end may be a Universal Terrestrial Radio Access Network (UTRAN), which includes at least one base station (Node-Bs, NB). In a Long Term Evolution (LTE) system, an Advanced Long Term Evolution (LTE-Advanced, LTE-A) system or a subsequent ...

Abstract

An apparatus and method for handling selection of a public land mobile network. The apparatus for processing a selection of a public land mobile network for a device-to-device communication includes a memory unit for storing instructions: when performing at least one public land mobile network search, detect a first public land mobile network a mobile network and a second public land mobile network, wherein the first public land mobile network does not provide a proximity service and the second public land mobile network provides the proximity service; and selecting the second public land mobile network to camp on the second public land mobile network; and a processing device, coupled to the storage unit, configured to execute the instruction in the storage unit.

Description

technical field [0001] The present invention relates to a device and method for a wireless communication system, and more particularly to a device and method for processing a public land mobile network for device-to-device communication. Background technique [0002] In order to improve the Universal Mobile Telecommunications System (UMTS), the 3rd Generation Partnership Project (the 3rd Generation Partnership Project, 3GPP) has developed a Long Term Evolution (LTE) system with better performance, which supports The 3rd Generation Partnership Project Release 8 (3GPP Rel-8) standard and / or the 3rd Generation Partnership Project Release 9 (3GPP Rel-9) standard are designed to meet increasing user demands. The LTE system is regarded as a new wireless interface and wireless network architecture that provides high data transmission rate, low latency, packet optimization, and improved system capacity and coverage. It consists of multiple evolved base stations (evolved Node- The E...
