Communication control device and communication control method

Abstract

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.

Description

technical field [0001] The present invention relates to a communication control device and a communication control method, in particular to a communication control device and a communication control method for communication using a subscriber line extension method. Background technique [0002] Currently, various communication control devices have been proposed in order to control communications of mobile communication terminal devices such as mobile phones. A world-standard communication system called W-CDMA (Wide band Code Division Multiple Access) or UMTS (Universal Mobile Telecommunications System) is applied to such a communication control device. According to this communication method, since one frequency is code-multiplexed and shared by a plurality of users, frequency efficiency is high, and high-speed communication can be flexibly provided by code selection. [0003] Also, the prior art of such a communication method is described in Non-Patent Document 1. The tran...

Problems solved by technology

Therefore, the control device at the destination is loaded with processing related to transmission and reception of data not required for processing, and thus consumes time and power that can be allocated to other processing that is required.

[0011] In addition, in general, since the U-plane has a larger amount of data than the C-plane, the load on the control device due to unnecessary processing increases.
