A mobile communication method includes: a step which establishes a second radio access link between a mobile station and a radio communication data combining device for “an area limit service” via a radio base station for “a public area service” when a first radio access link is established between the mobile station and the radio communication data combining device for “the area limit service” via the radio base station for “the area limit service”; and a step in which the radio communication data combining device for “the area limit service” combines the data for “the area limit service” transferred from the radio base station for “the area limit service” and the data for “the area limit service” transferred from the radio base station for “the public area service.”

There is provided a neighbor cell notifying apparatus capable of implementing more efficient notification to a mobile station within a range that can be notified of and monitored, when the mobile station in communication using a plurality of cells is notified of neighbor cell information. This neighbor cell notifying apparatus includes a cell information extracting part for extracting neighbor cell information items for specifying respective neighbor cells corresponding to each of the cells; a cell rank determining part for, based on the neighbor cell information items extracted, determining ranks of neighbor cell information items that the mobile station is to be notified of, in favor of neighbor cell information items about neighbor cells common to the cells; and a cell information notifying part for notifying the mobile station of a predetermined number of neighbor cell information items among the neighbor cell information items on the basis of the ranks determined.
摘要:
A piston for an automatic transmission, including a first piston member forming a cylindrical portion and a second piston member forming a bottom portion, wherein the first piston member has a plurality of engaging grooves formed in one of opposite axial end portions thereof, each of the engaging grooves having a radial surface extending in a radial direction of the first piston member, and the second piston member has a plurality of elongate claws (70) extending in a circumferential direction thereof and respectively corresponding to the engaging grooves, each elongate claw having a free end portion and a fixed end portion, and being bent in an axial direction of the second piston member such that the free end portion is spaced from the fixed end portion in the axial direction toward an open end of the piston, each elongate claw having a first engaging lug which is formed at the free end portion and which is held in engagement with the corresponding engaging groove and in pressing contact with the radial end face of the corresponding engaging groove.

In a communication system of a subscriber extension line system, there is provided a communication controller whereby the load of an unnecessary process to be applied on a communication controller relating to a destination of a mobile telephone is eliminated and the processing efficiency for communication control is enhanced. In a D-RNC which controls the communication of the mobile telephone and which is commonly connected with an S-RNC, the mobile telephone moves while maintaining the communication with the S-RNC. When the mobile telephone enters a cell relating to the D-RNC, the control data is transmitted or received between the S-RNC and the node for managing the mobile telephone. There are also provided: an IP address/UDP port number for RNSAP, reading/setting section 316 for acquiring an IP address identifying the S-RNC and an IP address identifying the node; an IP address/UDP port number for NBAP, reading/setting section 315; and an IP address/UDP port number exchange section 314 for notifying the other side of the S-RNC and the node of the acquired IP addresses, respectively. This allows a direct communication between the S-RNC and the node.

摘要:
Disclosed is a communication method for switching between a first connection state, in which a data unit is transmitted in a first size, and a second connection state, in which a data unit is transmitted in a second size which is larger than the first size. The communication method comprises a step of maintaining the size of a data unit at the first size in a case where there is a transition from the first connection state to the second connection state after there had been a transition from the second connection state to the first connection state.
摘要:
A radio base station in a first mobile communication system is disclosed. The radio base station includes a radio communication unit; a network communication unit; and a determining unit. If a massage received by the network communication unit from a switching station indicates that a mobile station is requesting a service which is not provided in the first mobile communication system but which is provided in, a second mobile communication system and it is determined by the determining unit that a handover to the second mobile communication system cannot be conducted, the network communication unit requests the switching station to release a connection with the mobile station. Then the radio communication unit reports to the mobile station that the connection should be released in accordance with an instruction from the switching station.
