Mobile communication system

摘要

A radio base station includes a mobile communication system that sends and receives control signals between a mobile station and a mobile switching center via a first radio bearer, a second radio bearer, and a wired bearer. The relay node includes a first radio bearer function, a second radio bearer function, an IP layer function, an SCTP layer function, and an application layer function. The radio base station includes a second radio bearer function, a wired bearer function, and an IP layer function. The mobile switching center includes a wired bearer function, IP layer function, SCTP layer function, and an application layer function. Keep-alive processing is performed between the SCTP layer function of the relay node and the SCTP layer function of the mobile switching center. Security processing is performed between the IP layer function of the relay node and the IP layer function of the mobile switching center.

1. A mobile communication system configured to send and receive control signals between a mobile station and a mobile switching center via a first radio bearer that is set between the mobile station and a relay node, a second radio bearer that is set between the relay node and a radio base station, and a wired bearer that is set between the radio base station and the mobile switching center, wherein
wherein the relay node comprises:
a first radio bearer function of the relay node for setting the first radio bearer;a second radio bearer function of the relay node for setting the second radio bearer; anda first layer function of the relay node provided as an upper layer function of the second radio bearer function of the relay node, wherein the radio base station comprises:
a second radio bearer function of the radio base station for setting the second radio bearer;a wired bearer function of the radio base station for setting the wired barer;a first layer function of the radio base station provided as an upper layer function of the second radio bearer function of the radio base station; anda second layer function of the radio base station provided as an upper layer function of the wired bearer function of the radio base station, wherein the mobile switching center comprises:
a wired bearer function of the mobile switching center for setting the wired barer; anda second layer function of the mobile switching center provided as an upper layer function of the wired bearer function of the mobile switching center, wherein the control signals are configured to be sent and received on a first session terminating between the first layer function of the relay node and the first layer function of the radio base station and a second session terminating between the second layer function of the radio base station and the second layer function of the mobile switching center, wherein keep-alive processing for the first session is configured to be performed between the first layer function of the relay node and the first layer function of the radio base station, wherein keep-alive processing for the second session is configured to be performed between the second layer function of the radio base station and the second layer function of the mobile switching center, wherein security processing is configured to be performed between the first layer function of the relay node and the first layer function of the radio base station, and wherein security processing is configured to be performed between the second layer function of the radio base station and the second layer function of the mobile switching center.
