| 20110077010 | METHOD FOR PROCESSING RADIO LINK FAILURE REPORT AND METHOD FOR ADJUSTING MOBILE PARAMETER - A method and a system for processing a Radio Link Failure (RLF) report, where when a User Equipment (UE) encounters an RLF in a first cell controlled by a first evolved base station and selects a second cell controlled by a second evolved base station to re-establish an Radio Resource Connection (RRC), are provided. The method includes sending, by the second evolved base station, the RLF report to every corresponding evolved base station according to the PCI of the first cell having been received from the UE, where the PCI of the first cell, the PCI of a second cell, the CRNTI of the UE in the first cell, and UE authentication information are carried in the RLF report, and authenticating, by every evolved base station the UE according to the UE authentication information. Another method for processing an RLF report, and two methods for adjusting a mobile parameter, are also provided. | 03-31-2011 |
| 20110164590 | METHOD FOR UE HANDOVER BETWEEN HOME NODE BS - The present invention provides a method for User Equipment (UE) handover between home Node Bs, comprising steps of: sending, by a source home Node B that stores the ID of the connected gateway, a message to the gateway, the message including the gateway ID and a destination home Node B ID; sending by the gateway a message to the destination home Node B identified by the destination home Node B ID to establish a radio bear of the destination home Node B for the UE; sending by the destination home Node B the radio bearer allocated to the UE to the gateway; sending by the gateway the radio bearer to the source home Node B; sending by the source home Node B the radio bearer to the UE; and completing by the UE a handover to the destination home Node B. With the present invention, successful handover between home Node Bs under the same access control can be guaranteed in the case of the same gateway. Meanwhile, it is not necessary to make any modification to the current 3GPP protocol signaling, and the present invention is compliant with the protocol signaling for interfaces Uu and Iu. | 07-07-2011 |
| 20110182244 | METHOD FOR SUPPORTING CONTEXT MANAGEMENT BY HOME NODE-B - A method for managing user context by a Home evolved NodeB (HeNB) is provided. The method includes requesting, by a Mobility Management Entity (MME), the HeNB to reserve a first type of User Equipment (UE) context information, obtaining, by the HeNB, the MME of the UE according to the first type of UE context information after receiving data, and notifying, by the HeNB, the MME of an arrival of the data. With the method according to the present invention, it is guaranteed by an HeNB system that a terminal can receive downlink signaling after activation of a local routing optimization service by the terminal. | 07-28-2011 |
| 20110210845 | ALLOCATING METHOD OF MOVING AREA LIST OF USER EQUIPMENT AND CORRESPONDING APPARATUS - A method of allocating the moving area list of user equipment which relating to wireless communication technology. Interacting signaling between network and UE is reduced. The utilization efficiency of network resource is enhanced. The method includes, receiving the area ID which is pre-defined from UE, acquiring the history information of the last allocated moving area list from the mobility management entity (MME) which allocated the last moving area list, allocating new moving area list according to the history information and the received area ID. Accordingly, a MME and UE are disclosed. | 09-01-2011 |
| 20110267963 | Apparatus and method of user equipment relocation - A method for relocating User Equipment (UE). The method includes a Source Home Node B (S-HNB) sending a Radio Access Network Application Part (RANAP) Relocation Required message and a RANAP Relocation Request message encapsulated in a RANAP User Adaptation (RUA) Direct Transfer message to an HNB gateway (HNB GW). The method also includes the HNB GW sending the RANAP Relocation Request message encapsulated in a RUA Direct Transfer message or in a RUA Connection message to a target HNB (T-HNB). The relocation method may have several advantages. For example, the HNB GW is not required to store a large amount of UE Context, thereby reducing the burden of the HNB GW. The interaction with the CN is decreased, thereby reducing the burden of the CN. The HNB GW is not required to construct RANAP relocation messages, thereby reducing the complexity of the HNB GW. | 11-03-2011 |
| 20110268086 | APPARATUS AND METHOD FOR SUPPORTING GATEWAY NODE RESELECTION IN COMMUNICATION SYSTEM - An apparatus and a method for supporting gateway node reselection in a communication system during a process in which a UE hands over from a source base station to a destination base station are provided. The apparatus includes the source base station for providing the destination base station with information for access control determination, the destination base station for making an access control determination according to the information provided by the source base station, the UE or a network for initiating a gateway reselection process according to the result of the access control determination. With the method, the reselection of Packet Data Network Gateway (PDN GW) or GGSN is implemented in a simple and reliable way by optimizing the existing signaling processes, in the case of user plane node reselection because UE changes position or handover to another base station. | 11-03-2011 |
