  • Patent number: 8965377
    Abstract: A method for reporting location information of a user is disclosed, wherein location information of user equipment (UE) is reported during a handover of the UE to another serving cell, and includes: a source evolved Node Base (eNB) initiating a handover procedure; during the handover procedure, the source eNB sending location reporting information to a target eNB, the target eNB acquiring the location information of the UE based on the location reporting information and reporting it to a Mobility Management Entity (MME) corresponding to the target eNB. The source eNB may notify the target eNB based on a handover request of the UE, wherein the target eNB reports the location information after the UE is handed over to another serving cell, so that the target eNB can report the location information of the UE to the MME during the handover procedure of the serving cells.

  • Publication number: 20140301367
    Abstract: A method and UE for processing data during cell handover in a Long Term Evolution (LTE) system are provided. The method includes: receiving, by User Equipment (UE), a Sequence Number (SN) of a Packet Data Convergence Protocol-Service Data Unit (PDCP-SDU) that is received by a Source Evolved Node B (S_eNB) from a Target Evolved Node B (T_eNB); discarding, by the UE, the PDCP-SDU that is received by the S_eNB from a re-transmission queue, and re-transmitting other PDCP-SDUs in the queue to the T_eNB. Thereby, UE would not re-transmit PDCP-SDU corresponding to received SN, which avoids re-transmission of useless PDCP-SDU, and saves radio resources comparing with prior solutions.

  • Patent number: 8797998
    Abstract: A method and device for indicating data re-transmission when area switching in LTE system, wherein the method comprises the following steps: S_eNB sends PDCP-SDU CN report to T_eNB in order to announce PDCP-SDU SN received, and T_eNB announces PDCP-SDU SN received by S_eNB to UE. Thereby, UE would not re-transmit PDCP-SDU corresponding to received SN, which avoids re-transmission of useless PDCP-SDU, and saves radio resources comparing with prior solutions.

  • Patent number: 8514813
    Abstract: The present invention provides a method for obtaining bearer condition during a handover of UE. The method includes: receiving, by a mobile management entity (MME), information of at least one bearer allowed to be accepted by a target base station (eNB) when the eNB makes an admission control for a UE based on received bearer information of the UE during handover of the UE; updating, by the MME, a UE-AMBR used by the target eNB based on the received at least one bearer. The present invention also provides an MME which enables the target side obtain actual bearer condition during handover of a UE.

  • Patent number: 8378814
    Abstract: 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.
