A method for supporting PDN GW selection, comprising the following steps of: receiving by an MME a local route optimization service request information; searching by the MME the IP address of a PDN GW which supports local route optimization according to the IP address of a PDN GWh; sending by the MME a bearer request establishment message to the PDN GWh. The method of the present invention can ensure core network equipment to find PDN GW correctly while HeNB system supports local route optimization.

The method for establishing a connection by a HNB comprising steps of: the HNB transmitting an “attachment request” message to an operation and maintenance center (OMC); the OMC transmitting an “attachment response” message to the HNB; the HNB establishing a connection with an MME indicated by the “attachment response” message. With the method proposed in the present invention, a UE can switch between HNBs in the same CSG through interface X2. Meanwhile, such information as the radio resource management and so on can be exchanged between two HNBs.

A method for updating location information of a UE is provided. A Node B transmits location information of the UE to an MME. An MME updates location information of the UE saved in a network as the location information of the UE from the Node B. The method supports the UE in a connection mode moving between different geographical domains without a need for domain update process. It also supports signaling in circuit domain to be transmitted in newly evolved network.

Disclosed is a method for performing switching between a macro evolved Node B (eNB) and a home eNB (HeNB) in a mobile communication system including broadcasting, by the HeNB, a length of an HeNB ID to a UE; notifying, by the UE, an HeNB indication information containing the length of the HeNB ID to the macro eNB; transmitting, by the macro eNB, a switching request message to a mobile station mobility management entity, the message including a target ID; finding, by the MME, the HeNB or an HeNB gateway according to the target ID, and performing a switching process from the macro eNB to the HeNB. With the described switching method for the mobile communication system, UE can move between the macro eNB and the HeNB.

摘要:
A method for supporting Multicast Broadcast Multimedia Service (MBMS) data transmission in a Long-term evolution (LTE) system includes a network entity (ECN) to which a user equipment (UE) is registered, receives an Activate MBMS context request message from the UE, and sends a Create MBMS UE Context Request message to a ECN that offers MBMS service. The ECN that offers MBMS service performs an authorization process with a Broadcast and Multicast Service Center (BM-SC) and sends a “Create MBMS UE Context Response” message to the ECN to which the UE is registered. The ECN to which the UE is registered sends an Activate MBMS Context Accept message to the UE. With the methods for supporting the transmission of MBMS data in the LTE system according to present invention, both the BM-SC and the ECN can find the downstream node so that service transmission paths may be found for MBMS data.
摘要:
A method for establishing a connection of a home Node B (HNB), the method comprising the steps of: transmitting, by the HNB, an attachment request message including an identifier of a closed subscriber group (CSG) where the HNB is located and information on location of the HNB to an operation and maintenance center (OMC); selecting, by the OMC a device establishing a connection with the HNB using the information on location of the HNB; transmitting, by the OMC, an attachment response message including information on the device to the HNB; establishing, by the HNB, a connection with the selected device. With the method proposed in the present invention, a UE can switch between HNBs in the same CSG through interface X2. Meanwhile, such information as the radio resource management and so on can be exchanged between two HNBs.

摘要:
A method for detachment of a mobile set within the equivalent route area moving between the communication systems comprising steps of: during the detachment process is implemented between a mobile set and a service node in one communication system, the service node generates one or more messages and transmits it to the service nodes in one or more communication system within the ERA. If the message is transmitted to the service node within the ERA of only one communication system, this service node transmits this message or the message generated according to this message to the service nodes within the ERA of the other communication system. With the method proposed in present invention, when a mobile is detached from two or more communication systems which share the same ERA, the service nodes in all communication systems within the ERA can still correctly manage the relevant information on this mobile set.
