Benefits of technology

[0030]Through the embodiments of the invention, while guarantying the benefit and dominant control right of the home network operator, the IP address of the default IP bearer for the roaming user may be allocated by the roaming network as much as possible, 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.

Problems solved by technology

This is to say, it is necessary for a user to perform the PDP context activating process before service communication, resulting in a relatively long time-delay for the user to turn from an idle state to a data communication state, this definitely does not meet the requirements of the evolved network.
The QoSs required by upper layer application services are different largely from each other, and usually cannot be satisfied by the QoS provided by the default IP bearer.
However, there are no definite strategy and method to realize this optimization at present.

embodiment one

[0036]As shown in FIG. 2 a core network of a radio evolved network mainly includes three logic function entities: Mobility Management Entity (MME), User Plane Entity (UPE), and Inter AS Anchor (Inter AS Anchor is a user plane anchor for mobility between different access systems). The MME corresponds to a control plane part of a Serving GPRS Support Node (SGSN) inside a current Universal Mobile Telecommunication System (UMTS), and is responsible for the mobility management of the control plane, including the management of user context and mobility states as well as the allocation of user contemporary ID and security functions. The UPE corresponds to a data plane part of a GGSN and SGSN inside the current UMTS system, and is responsible for initiating a paging for downlink data under the idle state, managing and saving IP bearer parameters and intra network route information. The Inter AS Anchor acts as a user plane anchor for mobility between difference access systems. The functions ...

embodiment two

[0054]If the service of default IP bearer in a future evolved network is not necessarily transparent to access network equipments (such as Evolved RAN (access network of future evolved network), MME / UPE, and Inter AS Anchor in FIG. 2), the above negotiation process may need to consider the supporting capability of the roaming network with respect to these non-transparent services. According to this respect, FIG. 4 shows another embodiment of the invention.

[0055]First, for the non-transparent services (such as IMS service, which is not transparent to the access network equipments when the IMS service needs support from the roaming network equipments) of default IP bearer, a series of service IDs or service types are defined, and a TLV (type-length-value) format may be adopted as follows:

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Patent Application No. PCT / CN2007 / 000276, filed Jan. 25, 2007, which claims priority to Chinese Patent Application No. 200610033435.1, filed Jan. 26, 2006, entitled “A Method for Optimizing Data Routing of Roaming User in 3GPP Evolved Network,” both of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The invention relates to mobile communication, and more particularly, to a method and system for implementing data routing of a roaming mobile user.BACKGROUND OF THE INVENTION[0003]In order to guarantee that an evolved mobile communication system may satisfy the continuously increasing requirements of users in a long term of future, the ability of possessing rapid increasing IP data service by the evolved mobile communication system should be enhanced, and the employment of packet technology in the mobile communication system should be further improved...
