Problems solved by technology

[0004] However, since data reordering (reconfiguration) is required at least at the service data unit (SDU: Service DataUnit) level within the target eNodeB, disadvantages arise in connection with the data transfer period between the source and target eNodeB

Embodiment Construction

[0026] First of all, in order to clarify the difference with the present invention, based on figure 1 A more detailed description of the current state of the art.

[0027] figure 1 is a message sequence diagram showing signal transmission and data transmission between the mobile wireless communication device 10, the source eNodeB 12, the target eNodeB 14, and the Access Service Gateway (Access Service Gateway) 16, the Access Service Gateway 16 in this example There are mobility management entity (Mobility Management Entity) and user plane entity (User Plane Entity).

[0028] Depend on figure 1 It can be seen that the access service gateway 16 does not receive information about the handover status until the target eNodeB 14 receives the handover acknowledgment signal 18 distributed from the mobile wireless communication device 10 . It can also be seen that from the time when the source eNodeB 12 sends the handover command (request) signal 20 to the mobile wireless communicat...

Abstract

Provided is a handover method used for a mobile radio communication device configured for communication with an access service gateway by an eNodeB configuration. The method has a step for distributing a handover display message to the access service gateway after a handover request is received from the eNodeB by the mobile radio communication device and before the handover is completed. The handover display provides a handover method having a role to prevent transmission of downlink data from the access service gateway at least until a further eNodeB message is received. Moreover, the present invention provides a related mobile radio communication network configuration and an eNodeB configuration.

Description

[0001] The present invention is based on and claims priority from British invention patent application No. 0611838.4 filed on June 15, 2006, and the entire contents disclosed in this patent application are incorporated in this specification by reference. technical field [0002] The present invention relates to handover procedures within a network of mobile wireless communication devices, and more particularly to a handover method, a network configuration operating according to such a method, and an evolved NodeB (eNodeB hereinafter) provided within the network. Background technique [0003] As a current ongoing review of 3GPP (3 rd Generation Partnership Project: 3rd Generation Partnership Project) in the various specifications provided as part of discussions, made various contributions to the issue of intra-LTE (Long Term Evolution: Long Term Evolution) mobility, including eNodeB handover process for data transfer between source and target eNodeB for uplink (UL) and downl...
