This object is to conclude an agreement for making an insertion interval of a pilot signal variable between radio communication apparatuses and improve a throughput of a communication. A pilot signal insertion interval acquiring unit 3 acquires the insertion interval of the pilot signal (known reference signal) which is optimal in a propagation path to a predetermined radio communication apparatus, from a signal sent through an antenna 9 and a receiving RF unit 1, or information sent from a higher layer. Then, in accordance with the insertion interval of this pilot signal, the pilot signal is inserted into a transmission data, and it is transmitted, or the insertion interval of the pilot signal is reported as the transmission data to a different radio communication apparatus. Thus, the insertion interval of the pilot signal in the propagation path can be made optimal. By the way, from a temporal variation quantity of a propagation response, the insertion interval of the pilot signal that becomes optimal is calculated, thereby enabling the acquisition of the insertion interval of the pilot signal that is more proper.

For instance, in a communication terminal apparatus 100 hierarchically classified to a plurality of layers depending on different processing functions such as OSI reference model, it is designed in such manner that a processing unit 303 belonging to a predetermined layer can selectively utilize a plurality of processing units 301 belonging to lower layer through control of an operation control unit 304 belonging to a predetermined layer. For instance, by referring to which processing is available among a plurality of processing units belonging to lower layer, which processing unit has better transmission efficiency in communication, or which processing unit can be used to perform communication with a desired communication partner, data distribution control means 309 controls data distributing means 307, and the data distributing means divides transmission data supplied from upper layer and distributes the data to a plurality of processing units belonging to the lower layer.

A test point analyzing apparatus determines a distinction between capability and incapability of insertion of a test point and a circuit modifying way when a test point is capable of being inserted for each of the test point types to each of the signal lines in a semiconductor integrated circuit by using circuit information, a test point insertion library, and test point insertion. Then, test point indexes to test point candidates capable of being inserted are calculated, and test point candidates having a large testability are selected based on the indexes, and the selected test point candidates are registered in test point information. Such processing is repeated until a predetermined condition of completing the test point analysis process is realized. In the apparatus, a test point index calculation portion calculates test point index information including CRF (Cost Reduction Factor) of each signal line from circuit information, determines a predetermined number of test point candidates in order of the CRF, and calculates COP (Controllability Observability Procedure, hereinafter referred to as test cost) when each of the test point candidates is assumed to be inserted. By setting candidates of the minimum COP as test points, a test point determining portion searches the other test point candidates not intersecting with an effect region of the test points in increasing order, and if there exists a test point candidate not intersecting with an effect region, the test point is added to a new test point group.

Disclosed is a technique for performing flexible service-level access control in real-time while suppressing occurrence of signaling. According to the technique, a network entity (AAA server 10) configured to perform access control sets correspondences between addresses of a communication terminal (UE) 40 and respective service contents of services that the communication terminal 40 receives, and notifies the communication terminal of the correspondences. Thus, the communication terminal is able to know the service contents corresponding to the addresses that the communication terminal uses. In a case where a service content of a service that the communication terminal receives is changed, the address used by the communication terminal is changed to an address corresponding to the changed service content. As a result, from the changed address, the communication terminal is able to know that the service content has been changed and to know the changed service content.

The invention relates to optimizing a data path between two communication nodes. A route optimization agent (ROA) is determined in the current network of the second communication node, preferably on the data path between the two communication nodes. Then, an IP tunnel is established between the first communication node and the ROA, the IP tunnel and the corresponding security association of said IP tunnel being based on the home address of the first communication node in its home network. The first communication node may have two IP tunnels based on the same home address, one to its home agent and one to the ROA. Corresponding routing entries and binding cache entries need to be established in the ROA and the first communication node so that all data packets between the two communication nodes are exchanged via the established IP tunnel over the ROA.
摘要:
Disclosed is a technique for reducing delay when a mobile communication terminal starts communication and reducing consumption of a power resource of the mobile communication terminal. An MN (mobile node) (1012) has plural interfaces (IF-1 (1030) and IF-2 (1028)). One interface IF-1 is connected to a connection point (serving PoA (1008)). When switching over from communication using the IF-1 to communication using the IF-2, the MN transmits a paging request message via the IF-1 and the serving PoA to a connection point (target PoA (1010)) attempted to connect using the IF-2. The target PoA that has received the paging request message reduces a beacon transmission cycle and sets transmission slots for the MN so that the connection of the MN can be established efficiently.
