AI Technical Summary

Problems solved by technology

This kind of information is not enough for eNodeB because it is impossible to distinguish whether the reported cell is from a private cell or a public cell, unless different TA value ranges are used for public and private cells
However, to avoid increasing the length of TAs to overcome capacity issues, it is not desirable to restrict different tracking areas for private and public cells

Embodiment Construction

[0034] refer to figure 1 , an example of a radio system to which an embodiment of the present invention can be applied is analyzed. In this example, the radio system is based on LTE / SAE (Long Term Evolution / System Architecture Evolution) network elements. However, the invention described in these examples is not limited to LTE / SAE radio systems, but can also be implemented in other radio systems, such as HSDPA (High Speed ​​Downlink Packet Access), HSUPA (High Speed ​​Uplink Packet Access), In), WIMAX (Worldwide Interoperability for Microwave Access), Internet HSPA or other suitable radio systems.

[0035] figure 1 The exemplary radio system includes an operator's service core 100 comprising the following elements: service management 102 , IMS (IP Multimedia Subsystem) 104 , MME (Mobility Management Entity) 106 and SAE GW (SAE Gateway) 108 .

[0036] Traffic between mobile terminals 150 , 151 and serving core network 100 is carried via national IP backbone network 120 , reg...

Abstract

There is provided a radio system comprising: one or more base stations of a public mobile network, at least one mobile terminal communicating with the one or more base stations, and a local breakout service network providing Internet protocol gateway services. A serving base station of a mobile terminal is configured to provide the local breakout service to the Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of the public mobile network for the mobile terminal; to provide information on neighboring cells in which the local breakout service can continue; to make a handover decision based on measurement reports received from the mobile terminal; and to transfer user context data including local breakout ser-vice related information to a target base station during handover for providing mobility within the local breakout service area for the mobile terminal.

Description

technical field [0001] The invention relates to a method, a radio system, a base station and a computer program distribution medium. Background technique [0002] Cellular operators can today provide local IP (Internet Protocol) connectivity in an area (local IP breakout) without roaming, where limited user mobility and IP session continuity is a challenge with roaming and global mobility Alternative to normal cellular packet data services that are permanently supported. Such local IP connectivity may be provided in local segments of urban centers or any limited geographic area, enterprise network or home where radio coverage is available. At a minimum, this local IP breakout can be provided using one radio cell / base station, and it can be extended to the wide radio coverage area of ​​the operator's nationwide domain (PLMN). For example, LTE / SAE (Long Term Evolution / System Architecture Evolution) services with roaming and global / inter-radio access mobility with IP session ...
