20130040644 | MOVEMENT PREDICTING METHOD - A movement predicting method is disclosed. The method utilizes at least one phone communicating in and moving between neighboring cells of base stations to predict population movement in a prediction interval. Firstly, obtain the traffic volumes in the cells generated by the phone and the handover information generated by the phone moving between the cells in a day. Next, calculate the traffic volumes and the handover information to obtain a movement probability for the population moving between the cells and an average residence time that the population stays in the region of each cell in the different periods of the day. Finally, according to the data obtained, predict an appearance probability that the population appears in each region at the end point of the prediction interval. | 02-14-2013 |
20140286224 | Service Continuity for Group Communication Over LTE eMBMS - A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. In one embodiment, The UE requests to switch the DL multicast traffic from the multicast MBMS bearer to the unicast EPS bearer upon detecting that the UE is approaching an MBMS coverage boundary. In another embodiment, the UE transmits an indication of preferred target cells to the network before performing a handover and thereby maintaining multicast service continuity of the group communication. | 09-25-2014 |
20150257178 | Method of Call Setup Time Reduction for Voice over LTE - Methods and apparatus are provided for a voice over LTE system to shorten the call set up time. In one novel aspect, the mobile origination (MO) UE starts the UE-initiated dedicated resource allocation before receiving any responses from the remote UE. In another embodiment, the mobile termination (MT) UE starts the UE-initiated dedicated resource allocation upon receiving the INVITE from the remote UE. In one embodiment, the UE adjusts the timeout value based on the PLMN information in its PLMN database. The timeout value can be set to be zero if early reservation is allowed. Upon timer expires, the UE starts UE-initiated dedicated resource allocation. In one novel aspect, the MO UE retrieves the codec information of a remote UE from its peer profile information database and uses a matching codec in its INVITE message. In another embodiment, the MT MO includes the SDP answer in its 180 RINGING message. | 09-10-2015 |
20150264741 | Method to Reduce Service Interruption - Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established. | 09-17-2015 |
20150282060 | Method of Device-Assisted Enhanced SIM Replacement - A method of supporting enhanced SIM replacement procedure is proposed. A UE detects that a first identification module running a first application is inserted. The first identification module belongs to a PLMN, and an enhanced service is provided by an operator of the PLMN via a second application. The UE sends a notification to the operator for obtaining a second identification module. The UE detects that the second identification module running the second application is inserted. The UE sends a second notification to the operator for activating the second identification module such that the UE is able to use the enhanced service provided by the operator. The device-assisted solution for SIM replacement complies with existing security/authentication model, has no standard charge, and complies with existing SIM replacement model and offers a simpler and more automatic procedure. | 10-01-2015 |
20160113053 | Method for Processing Unsuccessful PDN Establishment Request - A method of enhanced session management procedure is proposed. A user equipment, upon receiving a rejected PDN connectivity request with a cause code, automatically alters the rejected factor to fit network restrictions based on the received cause code. The UE then retries the PDN connectivity procedure by sending a subsequent PDN connectivity request using the altered factor. By automatically altering the rejected factor and reattempting to establish an EPS bearer for data service without user interaction, possible permanent rejection can be avoided in case of user error or unawareness. | 04-21-2016 |
20160113054 | Method for Maintenance of Maximum Number of Bearers When Maximum Number of Bearers Reached - A method of maintaining maximum number of bearers when maximum number of bearers reached is proposed. An enhanced SM/ESM procedure is proposed to synchronize between UE and network and to determine a precise maximum bearer number for protecting network resource and improving user experience. The UE determines the maximum bearer number based on a cause code contained in an SM reject message and updates the number under various network scenarios including system change. | 04-21-2016 |
20160135144 | Method and Apparatus for Heterogeneous Communication - A method of managing bandwidth resources provided by multiple network interfaces is proposed. When one or more network interfaces provide network bandwidth resources, a bandwidth manager manages all available bandwidth resources based on a list of decision criteria. The list of decision criteria includes energy efficiency, network throughput, channel condition, device mobility, and user preference. An application traffic flow distributer dynamically adjusts the amount of traffic flows on different network interfaces according to the joint decision based on the decision criteria. A network interface manager dynamically enables or disables each network interface according to the joint decision based on the decision criteria. Furthermore, a device movement analyzer analyzes and predicts device movement to facilitate accurate decision making of the bandwidth management. | 05-12-2016 |
