Abstract:
1. A radio access network comprising a radio network controller including a plurality of user plane servers for executing the transmission control of user's data regarding a mobile equipment and a control plane server for executing the transmission control of a control signal for transmitting the user's data wherein each of said user plane servers includes at least one of protocol entity for executing the transmission control of said user's data regarding the mobile equipment and U plane control section, wherein said control plane server includes at least one of protocol entity for executing the transmission control of a control signal for transmitting the user's data and C plane control section, and wherein a logical connection for transmitting control information is associated between said U plane control section and said C plane control section, in which case, said U plane control section and said C plane control section communicates with each other, wherein said control information includes at least one of more than one control command including a protocol entity identifier for uniquely identifying a protocol entity to be controlled between said user plane servers and said control plane server and more than one confirmation response command for said control command, wherein each of said C plane control section and said U plane control section includes a first table in which a one to one correspondence is given between a received request and a set of a response method for the protocol entity to be controlled and the control command and the response time, wherein one of said C plane control section and said U plane control section generates said control information, referring to said first table, and sends the same to the other of said C plane control section and said U plane control section, whereas the other of said C plane control section and said U plane control section extracts a set of the protocol entity identifier and the control command from the received control information, and distributes said extracted control command to the respective protocol entities included in said received control information, and further generates control information from the confirmation response received from said respective protocol entities and then sends the same as a reply to the one of said C plane control section and said U plane control section.
