摘要:
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.

A channel type switching method for Multimedia Broadcast and Multicast Service (MBMS) point-to-point (P-t-P) channel and point-to-multi point (P-t-M) channel is provided. When a user equipment (UE) moves to a cell in a drift radio network controller (DRNC) with an Iur interface, the DRNC decides to switch between a common channel and a dedicated channel and then notifies a serving radio network controller (SRNC) of MBMS channel type and common channel parameters.

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 transmitting a short signaling in a Media Access Control-e Packet Data Unit (MAC-e PDU) includes sending control information bits incorporated with padding bits of the MAC-e PDU considering the padding bits from a User Equipment (UE) to a Node B, and sending a scheduling signaling from a service Node B to the UE according to the control information bits. Scheduling request information is transmitted with the existing padding bits. If every Transmission Time Interval (TTI) has padding bits, the UE may send the scheduling request signaling to Node B in every TTI. Therefore, the reference is provided for the Node B, and no extra load is caused to the system.

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.

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 PHN GWh. The method of the present invention can ensure core network equipment to find PDN GW correctly while HeNB system supports local route optimization.

A method for managing key in Multimedia Broadcast/Multicast service comprising steps of defining a valid MTK ID interval for each generated MSK and sends it to a UE along with a MSK by a BMSC; after receiving the MSK, saving a valid MTK ID interval of the MSK by the UE; and defining a MTK ID for each generated MTK encrypted with the MSK and sending the MTK ID and the MTK to the UE after encrypting them with the MSK by the BMSC This MSK is valid only when the transmission of the MTK within MTK ID interval is in operation. Therefore, once the UE finds out that some newly received MTK's MTK ID is beyond said MTK ID, it deletes the MSK that is applied in said MTK transmission's encryption correspondingly.
