Method and system for implementing data routing of roaming user
First Claim
1. A method, comprising:
- receiving, by a Home Subscriber Server (HSS), a request message from a mobility management entity (MME), wherein the request message comprises a public land mobile network (PLMN) identifier (ID) of a roaming network where a user equipment (UE) is currently located;
determining, by the HSS, whether the roaming network is allowed to allocate an Internet Protocol (IP) address to a default IP bearer of the UE according to the PLMN ID and a roaming strategy corresponding to the PLMN ID and an identifier of the UE, wherein the roaming strategy indicates whether the roaming network is allowed to allocate the IP address to the default IP bearer of the UE; and
sending, by the HSS, a response message to the MME, wherein the response message comprises an information element that indicates whether the roaming network is allowed to allocate an IP address to a default IP bearer of the UE.

Abstract
A method and system for implementing data routing of a roaming user are disclosed. The method comprises: configuring a roaming protocol between the home network and the roaming network; during the registering process of the user in the roaming network, performing an interactive negotiation between the home network and the roaming network, so as to determine one of the home network and the roaming network to allocate IP address according to the roaming protocol between the home network and the roaming network; and establishing the IP access bearer based on the IP address. A corresponding system is also provided. The routing of the roaming user data plane could be optimized under the control of the home network operator, and the IP address of the default IP bearer for the roaming user could be allocated by the roaming network as much as possible, while guaranteeing of the home network operator'"'"'s interest and dominant position, so as to optimize the routing of the data plane for the roaming user, improve the performance of the data service and bring a better service experience to the roaming user.

6. A home subscriber server (HSS), comprising:
-
a receiving unit configured to receive a request message from a mobility management entity (MME), wherein the request message comprises a public land mobile network (PLMN) identifier (ID) of a roaming network where a user equipment (UE) currently is located; a processing unit configured to determine whether the roaming network is allowed to allocate an IP address to a default IP bearer of the UE according to the PLMN ID and a roaming strategy corresponding to the PLMN ID and an identifier of the UE, wherein the roaming strategy indicates whether the roaming network is allowed to allocate the IP address to the default IP bearer of the UE; and a sending unit configured to send a response message to the MME, wherein the response message comprises an information element that indicates whether the roaming network is allowed to allocate an IP address to a default IP bearer of the UE. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus, comprising:
-
a receiver configured to receive a request message from a mobility management entity (MME), wherein the request message comprises a public land mobile network (PLMN) identifier (ID) of a roaming network where a user equipment (UE) currently is located; a processor coupled to the receiver and configured to determine whether the roaming network is allowed to allocate an Internet Protocol (IP) address to a default IP bearer of the UE according to the PLMN ID and a roaming strategy corresponding to the PLMN ID and an identifier of the UE, wherein the roaming strategy indicates whether the roaming network is allowed to allocate the IP address to the default IP bearer of the UE; and a transmitter configured to send a response message to the MME, wherein the response message comprises an information element that indicates whether the roaming network is allowed to allocate an IP address to a default IP bearer of the UE. - View Dependent Claims (12, 13, 14, 15)
