Abstract: A method for reducing the handover frequency by a femto gateway in femtocell networks includes the steps: receiving a measurement report from a communication device by an initial femtocell; transmitting a relocation required message to a femto gateway by the initial femtocell if the signal strength thereof is below a threshold; ignoring the relocation required message and enabling the timer by the femto gateway after receiving the relocation required message; determining whether the cell ID included in the call reestablishment request message is classified as “femtocell” or not by the femto gateway before the timer expires; if so, rebuilding the link to the femtocell in response to the cell ID by the femto gateway.

Abstract: A wireless mobile communication method is provided. If a wireless mobile communication service arrives at a core network, the core network sends a paging signal to at least one macro base station and at least one Femto gateway. After the macro base station receives the paging signal, the macro base station pages the at least one mobile station within the coverage of the macro base station. The Femto gateway blocks the paging signal sent from the core network, so that the at least one Femto base station covered by the Femto gateway does not page the mobile station. After a destination mobile station receives the paging signal, the destination mobile station establishes a signaling connection, so that a call to a destination mobile station is established.

Abstract: In a Vehicular Ad Hoc Network (VANET) a hybrid method combines SDMA (Space Division Multiple Access) and dynamic TDMA (Time Division Multiple Access) that divides the roadway into regions (whose size is larger than the SDMA unit) where each region is allocated a pool of radio channels based on SDMA and may contain a limited number of vehicles. Vehicles within the same region compete for and access the channels using dynamic TDMA. A channel allocation scheme that maps the pool of channels to the regions such that when a vehicle acquires multiple channels (time slots) in a region, the intervals among the channels are as uniform as possible, thus minimizing the waiting time of the messages to be broadcast by the vehicle, which is critical for safety related applications. This solution is referred to as R-SDMA (Region based SDMA).

Abstract: A method for reducing the handover frequency by a communication device in femtocell networks includes the steps: measuring the radio signal strength by a communication device and storing the information of the serving base station into a cache memory; checking whether the stored information in the cache memory is classified as “femtocell” or not; if so, deleting the macrocell's information from the measurement report by the communication device and transmitting this to the serving base station; when the radio link failure occurred, checking whether the stored information in the cache memory is classified as “femtocell” or not; if so, initiating a timer; detecting an available femtocell before the timer expires; transmitting a call reestablishment request message to the available femtocell for rebuilding the link.

Abstract: A channel buffering method is for dynamically altering a number of channels for an Internet protocol television (IPTV). The method is applicable for a home gateway (HG) having a channel section used for channel buffering. After the HG has received two consecutive channel-switching requests, the HG compares whether the two requests are similarly directed to switching a channel towards the same direction or not; if yes, a cumulative switching frequency is set, and two trimming numerical values are set through the cumulative switching frequency, and thus, the channel section for buffering the channels can be dynamically adjusted through the two trimming numerical values.

Abstract: A reporting method for a data transmission device within a sensing region that comprises at least one data transmission device(s) for receiving a sensed data from a sensor device, transmitting the sensed data to a server, and broadcasting a message. Furthermore, the data transmission device enters a listening state for receiving the sensed data from the sensor device. If the data transmission device does not receive the message from any of the other data transmission device(s), will enter a reporting state for transmitting the sensed data and broadcasting the message. In addition, the data transmission device enters a sleeping state, if a reporting counter equals to zero. Therefore, the power wastage of the data transmission devices can be reduced.

Abstract: A method of relay transmission in a mobile communication system. The mobile communication system includes at least one base station and a plurality of user equipment units (UEs). When one of the UEs attempts to send a message to the base station, this one of the UEs, referred to as a requesting UE, is capable of using the method of relay transmission to send messages to the base station via another one or more UEs, referred to as relay UEs. The method of relay transmission includes the following steps. First, a relay request confirmation procedure for the requesting UE and the relay UE is performed. Second, a base station confirmation procedure for the requesting UE, the relay UE, and the base station is executed. Next, an identity authentication procedure for the requesting UE, the relay UE, and the base station is performed. After that, a relay start confirmation procedure for the requesting UE and the relay UE is executed.
