20130157662 | MULTI-SIM MULTI-STANDBY COMMUNICATION TERMINAL, AND SYNCHRONIZATION DEVICE AND METHOD THEREOF - A multi-SIM multi-standby communication terminal, and a synchronization device and method thereof are provided. The synchronization method includes: searching, by the first card, for a network and camping on a first cell after the communication terminal is powered on; controlling the second card to camp on the first cell; determining, by the first card, if there is a second cell qualified for reselection based on the result of neighbouring cells measurement, and if the determination result is YES, the first card reselecting the second cell; and controlling the second card to reselect the second cell after the first card camps on the second cell. This disclosure has the following advantages: the efficiency of paging information reception and neighbouring cells measurement is increased, power consumption is reduced, the time for camping on and cell reselection is reduced, and the implementation of the physical layer is simplified. | 06-20-2013 |
20130315151 | SERVICE PROCESSING METHOD, A BASEBAND PROCESSOR CHIP AND A TERMINAL - A service processing method, a baseband processor chip and a terminal are disclosed in embodiments of this invention, wherein the service processing method comprises: in response to a need for processing a CS domain service by a terminal, identifying whether PS domain data that is being received/transmitted in a PS domain service currently processed by the terminal is critical data for maintaining the QoS level of the PS domain service; in response to that the PS domain data being received/transmitted is not critical data, suspending the processing of the PS domain service and processing the CS domain service. The embodiment of this invention enables a terminal of Class B to process a CS domain service during the process of receiving/transmitting PS domain data. | 11-28-2013 |
20140128070 | SELF-ADAPTIVE COMMUNICATIONS NETWORK SELECTION - A public land mobile network (PLMN) selection procedure may be generated that, when implemented, disables at least one resource of a particular mobile device to prevent a scan of particular ones of PLMNS that exhibit supported access technologies, and/or supported frequency bands of supported access technologies, incompatible with a preferred operation of the particular mobile terminal. | 05-08-2014 |
20140146667 | MOBILE TERMINAL AND SERVICE PROCESSING METHOD THEREOF, AND BASEBAND PROCESSING CHIP - Disclosed are a mobile terminal and a service processing method thereof, and a baseband processing chip are disclosed in the embodiments of this invention, wherein the service processing method of the mobile terminal comprises: in response to the situation that a first user card in an on-network state is required to process a high real time service, identifying whether PS domain data being received/transmitted in a PS domain service currently processed on a second user card is the critical data for maintaining the QoS level of the PS domain service, wherein the high real time service has higher requirement to real-time than the PS domain service, and the first user card and the second user card belong to the multiple user-cards inserted in the same mobile terminal; in response to the PS domain data being received/transmitted is non-critical data, suspending the processing of the PS domain service and processing the high real time service. Embodiments of this invention allow a multi-card multi-standby mobile terminal based on a single RF single baseband scheme to process a high real time service on other user cards during processing a PS domain service on a user card. | 05-29-2014 |
20140248872 | METHOD FOR JUDGMENT AND RESIDENCY OF MULTI-CARD MOBILE TERMINAL SERVICE PROVIDER - Methods for determination and residency of service provider of a multi-card mobile terminal are provided. A method for the residency of the multi-card mobile terminal comprises: when some or all cards belong to the same service provider, said cards will reside in the same cell. Some embodiments of the present invention acquire IMSI corresponding to each card and extract HPLMN or EHPLMN from the IMSI to identify from card storage information rapidly and accurately cards in the mobile terminal that belong to the same service provider, and make those cards reside in the same cell during starting-up stage, cell reselection, or network recovery under the circumstance of a plurality of cards belonging to the same service provider, thus reducing the realization difficulties in measurement, idle standby, synchronous maintenance, etc., stabilizing the system and optimizing the performance of mobile terminal. | 09-04-2014 |
20150103739 | OPTIMIZING SUPPLEMENTARY SERVICE OPERATIONS FOR LTE-ENABLED DEVICES - A method of optimizing transactions involving Call Independent Supplementary Service (CISS) data on a Long Term Evolution (LTE) device may include receiving an indication that the CISS data should be transmitted between the device and a core network. The method may also include determining whether the device is standing by in a packet-switched LTE network or standing by in a 3G/2G network. In response to a determination that the device is standing by in the packet-switched LTE network, the method may additionally include packaging the CISS data in a control layer message and sending the control layer message between the core network and the device in the packet-switched LTE network. In response to a determination that the device is standing by in the circuit-switched 3G/2G network, the method may further include sending the CISS data between the core network and the device in the circuit-switched 3G/2G network. | 04-16-2015 |
20150117401 | CIRCUIT-SWITCHED FALLBACK DELAY MITIGATION - System and methods for mitigating circuit-switched fallback delay. A user equipment may initiate connection of the user equipment to a packet-switched network. A request may be sent by the user equipment to the packet-switched network to access a circuit-switched service. A timer may be started to determine elapsed duration between sending the request and receiving a response from the packet-switched network that confirms resource allocation to access the circuit-switched service. The user equipment may select in response to timer expiration, indicating absence of response to the request, a particular algorithm when implemented initiates connection of the user equipment to a particular circuit-switched network to access the circuit-switched service. | 04-30-2015 |
20150138974 | SUPPLEMENTARY SERVICE IMPLEMENTATION METHOD, LTE NETWORK SYSTEM AND MOBILE TERMINAL - A supplementary service implementation method, a Long Term Evolution (LTE) network system and a mobile terminal are provided. The method may include: receiving an Uplink NAS Transport message from a mobile terminal; analyzing the Uplink NAS Transport message; and performing a supplementary service if an SS message is determined to be contained in the Uplink NAS Transport message based on a NAS message container of the Uplink NAS Transport message. The method in the present disclosure can solve problems that an LTE terminal can not directly provide CISS when it is in an LTE network, or it has to fall back to a circuit-switched 3G/2G network so as to support CISS. Therefore, the method can reduce overheads introduced by network switching, and improve performances of LTE networks and LTE mobile terminals. | 05-21-2015 |
