A cell measurement method used in a mobile station camping on a serving cell is provided, wherein the serving cell sends system information of neighbor cells to the mobile station. A first set of the neighbor cells is determined based on a measurement rule for cell reselection. A second set of the neighbor cells is determined based on a report request for radio link establishment. A subset is chosen from the second set. Finally, the neighbor cells of a union of the first set and the subset are measured.

Method of cell measurement based on cell reselection and measured report in UMTS cellular system

A method for controlling radio links in a cellular communication system. The method comprises: receiving an active set update message from the system controller via at least one of the first radio link and the second radio link at the first user equipment to direct the first user equipment to terminate the first radio link, determining a communication status of the first radio link according to a current quality of the first radio link and a current quality of the second radio link after receiving the active set update message, and managing the first radio link and the second radio link according to the communication status.

Methods for controlling radio links in a cellular communication system

A method for handling data transmission by a mobile station with a first RF module and second RF module is provided. The mobile station is coupled to a computer acquiring an IP address IP(U). A packet with a source IP address IP(U) and a destination IP address IP(Y) corresponding to an access network is received by the mobile station. The first RF module is assigned to transmit the received packet by replacing the source IP address IP(U) with a source IP address IP(A). Another packet with the source IP address IP(U) and destination IP address IP(Y) is assigned to the second RF module, and the source IP address IP(U) is replaced by a source IP address IP(B). The replaced packets are transmitted to the access network via the first and second RF module respectively.

A system for handling packet-switched data transmission is provided. The system includes a first RF module, a second RF module, a first subscriber identity card camping on a cell via the first RF module, a second subscriber identity card camping on the same cell or a different cell via the second RF module and a load balancing unit. The load balancing unit receives an uplink IP packet, determines one subscriber identity card from the first and second subscriber identity cards when the uplink IP packet comprises information regarding an unestablished connection of a recognized application, and transmits the uplink IP packet to a destination via the determined subscriber identity card and the RF module corresponding to the determined subscriber identity card.

The invention discloses a method for coordinating protocol stack entities to share a single radio resource, executed by a processor of a mobile station, including the step of: after a first protocol stack entity for a first subscriber identity card enters a TALKING mode or enables a dial-up service, forcing a second protocol stack entity for a second subscriber identity card to release the radio resource or suspend utilization of the radio resource, and enabling the radio resource to be utilized to perform requisite operations or procedures of the TALKING mode or the dial-up service.

Method and system for coordinating protocol stack entities to share single radio resource

A communication apparatus has at least one radio transceiver module, a first subscriber identity card with a first address and a second subscriber identity card with a second address. The first subscriber identity card camps on a first cell belonging to a first wireless network via the radio transceiver module, and the second subscriber identity card camps on a second cell belonging to a second wireless network via the radio transceiver module. The communication apparatus includes first processor logic coupled to the radio transceiver module, the first subscriber identity card and the second subscriber identity card, receiving a communication request requesting for establishing wireless communication between the first subscriber identity card and a peer communication entity.

Communication apparatuses for handling apparatus terminated or originated communication requests with increased communication capability and methods thereof

A communication apparatus has at least one radio transceiver module, a first subscriber identity card and a second subscriber identity card, where the first subscriber identity card corresponds to a first public land mobile network (PLMN), and the second subscriber identity card corresponds to a second PLMN. The communication apparatus includes processor logic determining whether the first PLMN and the second PLMN are the same, and for suspending a measurement procedure and a cell reselection procedure of one of the first subscriber identity card and the second subscriber identity card to reduce battery power consumption. Processor logic further triggers an unsuspended measurement procedure to tune the radio transceiver module to a plurality of corresponding channel frequency/frequencies of the neighbor cells.

The invention provides a method for positioning a user equipment. First, a plurality of wireless links between the user equipment and a plurality of mobile networks are established. A plurality of first location information sets describing a location of the user equipment are then obtained from the mobile networks through the wireless links. The first location information sets are then converted to a plurality of second location information sets with a predetermined format. The second location information sets are then combined to estimate a third location information set describing the location of the user equipment.

Method for positioning user equipment accessing multiple mobile networks

A communication apparatus is provided. The communication apparatus includes a processor, a first and a second subscriber identity card and at least one radio transceiver module. The processor is coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, merges a first neighbor cell list and a second neighbor cell list to obtain a merged neighbor cell list, tunes the radio transceiver module to the corresponding channel frequency/frequencies of the neighbor cells in the merged neighbor cell list to respectively receive signals from the neighbor cells therein, and accordingly measures and evaluates quality of the neighbor cells therein.

A communication apparatus is provided. A first subscriber identity card is with a first address and camps on a first cell. A second subscriber identity card is with a second address and camps on a second cell. After receiving a communication request requesting for establishing wireless communication between the first subscriber identity card and a peer communication entity, a processor activates a service instructing the second wireless network to transfer a future apparatus terminated communication request of the second subscriber identity card to the first subscriber identity card via the first cell.
