Abstract

A communication system, in which a mobile terminal uses a data path that was generated with an ISP network by a base station in a home network to access a NW via the ISP network, includes an authentication means and connection control means in the ISP network. The base station accepts an access request from the mobile terminal and transmits information relating to the base station and the mobile terminal to the connection control means. The authentication means determines based on the information whether a linking service that connects to the home NW without traversing the ISP network can be provided to the mobile terminal, and if the linking service can be provided, notifies this information to the connection control means. Based on this notification, the connection control means requests the base station to generate a data path for providing the linking service, and the base station generates the data path.

First claim

What is claimed is:

1 . A communication system comprising:
a user equipment (UE); a base station; and a mobility management equipment (MME); wherein the UE transmits, to the base station, an attach request message; the base station sends, to the MME, the attach request message and a first information, which the first information is regarding to that the base station has a local access function.

2 . The communication system according to claim 1 , wherein
the MME sends, to the base station, an attach accept message including a second information, which the second information is for enabling direct user plane path between the base station and the local access function

3 . The communication system according to claim 1 , wherein
the base station transmits, to the UE, a RRC Connection Reconfiguration message; the UE transmits, to the base station, a RRC Connection Reconfiguration Complete message; and the base station sends, to the MME, an Attach Complete message.

4 . The communication system according to claim 1 , wherein
the local access function enables the UE connected via the base station to access other IP capable entities in the same residential/enterprise IP network without user plane traversing the mobile operator's network except the base station subsystem.

5 . The communication system according to claim 2 , wherein the second information is sent, when the local access is valid by using subscription data.

6 . The communication system according to claim 1 , wherein
the base station broadcasts a system information containing a third information regarding to local access.

7 . A user equipment (UE) comprising:
a transmission interface configured to transmit, to a base station, an attach request message, which the attach request message is forwarded, to a mobility management equipment (MME) by the base station, together with transmitting a first information, which the first information is regarding to that the base station has a local access function; and a reception interface configured to receive, from the base station, a RRC Connection Reconfiguration message

8 . The UE according to claim 7 , wherein
the RRC Connection Reconfiguration message includes a second information, which the second information is for enabling direct user plane path between the base station and the local access function.

9 . The UE according to claim 7 , wherein the transmission interface is further configured to transmit, to the base station, a RRC Connection Reconfiguration Complete message

10 . The UE according to claim 7 , wherein
the local access function enables the UE connected via the base station to access other IP capable entities in the same residential/enterprise IP network without user plane traversing the mobile operator's network except the base station subsystem.

11 . The UE according to claim 8 , wherein
the second information is sent, when the local access is valid by using subscription data.

12 . The UE according to claim 7 , wherein
the reception interface is further configured to receive, from the base station, a system information containing a third information regarding to local access.

13 . A base station comprising:
a reception interface configured to receive, from a user equipment (UE), an attach request message; and a transmission interface configured to send, to a mobility management equipment (MME), the attach request message and a first information, which the first information is regarding to that the base station has a local access function.

14 . The base station according to claim 13 , wherein
the reception interface is further configured to receive, from the MME, an attach accept message including a second information, which the second information is for enabling direct user plane path between the base station and the local access function.

15 . The base station according to claim 13 , wherein
the transmission interface is further configured to transmit, to the UE, a RRC Connection Reconfiguration message; the reception interface is further configured to receive, from the UE, a RRC Connection Reconfiguration Complete message; and the transmission interface is further configured to send, to the MME, an Attach Complete message.

16 . The base station according to claim 13 , wherein
the local access function enables the UE connected via the base station to access other IP capable entities in the same residential/enterprise IP network without user plane traversing the mobile operator's network except the base station subsystem.

17 . The base station according to claim 14 , wherein
the second information is sent, when the local access is valid by using subscription data.

18 . The base station according to claim 13 , wherein
the transmission interface is further configured to broadcast a system information containing a third information regarding to local access.

19 . A mobility management equipment (MME) comprising:
a reception interface configured to receive, from a base station, an attach request message and a first information, which the attach request message is transmitted from a user equipment (UE) and which the first information is regarding to that the base station has a local access function; and a transmission interface configured to send, to the base station, an attach accept message including a second information, which the second information is for enabling direct user plane path between the base station and the local access function.

20 . The MME according to claim 19 , wherein
the local access function enables the UE connected via the base station to access other IP capable entities in the same residential/enterprise IP network without user plane traversing the mobile operator's network except the base station subsystem.

21 . The MME according to claim 19 , wherein
the second information is sent, when the local access is valid by using subscription data.
