Method and device for transferring and receiving message in roaming system
First Claim
1. A data communication method of a mobility management entity (MME) of a mobile communication system, the method comprising:
- receiving a message including an XML configuration access protocol (XCAP) address corresponding to an XCAP server among at least two servers included in an internet packet data network (PDN) from a terminal in a roaming network of the mobile communication system for connecting only to the XCAP server;
checking at least one of subscription information of the terminal and network operator policy based on the received message; and
transmitting, when the terminal is allowed to access the XCAP server of the internet PDN as a result of the checking, a create session request message generated based on the received message to a gateway,wherein the create session request message includes the XCAP address and an indicator indicating that the terminal is allowed to connect only to the XCAP server corresponding to the XCAP address of the at least two servers included in the internet PDN.

Abstract
A method of transferring and receiving data by a mobility management entity (MME) in a mobile communication system according to an embodiment of the present invention includes receiving, from equipment, a message that includes the address of an XML configuration access protocol (XCAP) and is used to access an Internet packet data network (PDN); checking any one of subscription information on the equipment and a network carrier policy, on the basis of the received message; and delivering a create session request message to a gateway on the basis of the received message if the equipment is accessible to the PDN as the result of the check, wherein the create session request message includes an indicator that accesses the XCAP server. according to an embodiment, roaming equipment may transfer and receive an XCAP related message. Moreover, as the roaming equipment receives the XCAP related message, the present invention has an effect of being able to prevent undesired traffic due to another data packet from occurring.

4. A data communication method of a terminal of a mobile communication system, the method comprising:
-
transmitting, by the terminal in a roaming network of the mobile communication system, to a mobility management entity (MME) a message including an XML configuration access protocol (XCAP) address corresponding to an XCAP server among at least two servers included in an internet packet data network (PDN) for connecting only to the XCAP server; and performing RRC connection reconfiguration with a base station based on the message, wherein the MME checks at least one of subscription information of the terminal and network operator policy based on the message transmitted to the MME and transmits, when the terminal is allowed to access the XCAP server of the internet PDN as a result of the checking, a create session request message generated based on the message transmitted to the MME to a gateway, the create session request message including the XCAP address and an indicator indicating that the terminal is allowed to connect only to the XCAP server corresponding to the XCAP address of the at least two servers included in the internet PDN. - View Dependent Claims (5, 6)
