| 20120100862 | METHOD FOR RESOLVING DATA CONFLICTS AND MOBILE TERMINAL - The invention provides a method for resolving data conflicts and a mobile communication terminal. The embodiment about the method of the invention includes: a mobile terminal determining a time slot in a frame i for receiving a first data block; if a second data block needs to be received in the frame i, the mobile terminal determining a relationship between the time slot for receiving the first data block and a time slot for receiving the second data block; and if the time slots for receiving the first data block and the second data block are not the same and not adjacent, the mobile terminal receiving the first data block and the second data block sequentially according to the time slots in the frame i. The embodiment of the invention further provides a mobile terminal for implementing the method described above. The invention could receive multiple data blocks in a frame i and decrease the number of data blocks being discarded. | 04-26-2012 |
| 20120057525 | METHOD OF RESOLVING RECEPTION CONFLICTS FOR MULTI-CARD MULTI-STANDBY MOBILE TERMINAL - The present invention provides a method of resolving reception conflicts for a multi-card multi-standby mobile terminal, which is for resolving the conflicts of the mobile terminal based on Goble System for Mobile communication (GSM) network and in the standby mode, including: acquiring synchronization result with base stations and judging if there are time slot conflicts between multiple SIM cards of the multi-card multi-standby mobile terminal according to the synchronization result; if the conflicts being non-time slot conflicts, receiving and processing data of different SIM cards in different time slots of a TDMA frame; and if the conflicts being time slot conflicts, receiving and processing data of a non-current SIM card in redundant frames of BCCH or CCCH of a current SIM card. The present invention manages the logical channel conflicts with other SIM cards through using the redundant frames corresponding to the BCCH or CCCH of a SIM card, thereby resolving the signal conflicts because of the signals from different base stations being not synchronized for a dual-card dual-standby handset and is compatible with the prior art. | 03-08-2012 |
| 20120021804 | METHOD FOR SOLVING CONFLICT BETWEEN NETWORK SEARCHING AND MOBILE PHONE TRAFFIC AND A MULTI-CARD MULTI-BY MOBILE PHONE - A method for solving conflict between network searching and mobile phone traffic of a multi-card multi-standby mobile phone is provided. The method comprises storing network searching information of a first user card and processing the mobile phone traffic of a second user card, when conflict occurs between the network searching of the first user card and the mobile phone traffic of the second user card, and continuing to perform the network searching according to the stored network searching information of the first user card after completing the mobile phone traffic, when processing time of the mobile phone traffic of the second user card is less than or equal to a time threshold value. A multi-card multi-standby mobile phone is provided too. The mobile phone comprises a RAM for storing the network searching information, a timer unit for measuring the processing time of mobile phone traffic, a comparing unit set with the time threshold value for comparing the processing time of the mobile phone traffic with the time threshold value, and a MCU for continuing to perform the network searching according to the stored network searching information of the first user card when the processing time of the mobile phone traffic is less than or equal to the time threshold value. The present invention promotes the efficiency of the network searching. | 01-26-2012 |
| 20120021734 | METHOD FOR RESOLVING CONFLICT BETWEEN NETWORK SEARCHING AND TRAFFIC AND MULTI-CARD MULTI-STANDBY MOBILE PHONE - A method for resolving conflict between network searching and traffic includes: determining if a service request corresponds to mobile originated traffic or mobile terminated traffic, when a second user card receives the service request during a process of the network searching of a first user card; temporarily suspending the mobile originated traffic and continuing to perform the network searching of the first user card, when the service request corresponds to the mobile originated traffic; and temporarily suspending the network searching of the first user card, firstly processing the mobile terminated traffic, and continuing to perform the network searching of the first user card after completing the mobile terminated traffic, when the service request corresponds to the mobile terminated traffic. A multi-card multi-standby mobile phone of the present invention includes at least two types of user card, a communication unit for transmitting communication information, a microcontroller unit and a determining unit. The present invention avoids impact of the network searching to the mobile originated traffic and the mobile terminated traffic. | 01-26-2012 |
| 20120021726 | MULTI-CARD MOBILE TERMINAL AND METHOD FOR RECEIVING SYSTEM MESSAGES THEREOF - The invention provides a method for receiving system messages for a multi-card mobile terminal comprising: acquiring system messages received by any user identity card of a multi-card mobile terminal from network; and storing the system messages in a buffer, so that each user identity card acquires the system messages from the buffer directly. The invention resolves the problem that a plurality of user identity cards receiving same system messages repeatedly brings about high system cost and decreasing the time for network selection and cell reselection. | 01-26-2012 |
| 20120020394 | APPLICATION PROCESSOR, MODEM AND METHOD FOR COMMUNICATING THEREBETWEEN - The invention discloses a method for communicating an application processor and a modem. A physical link is provided between the application processor and the modem and corresponds to multiple virtual channels. The modem is embedded in a user equipment, and the user equipment is adapted for multiple user identification module cards. The method comprises: establishing, by the application processor, a relation of combining virtual channels to the user identification module card for receiving the service requests when service requests are sent to at least a user identification module card of the user equipment; and transferring the service requests to the user identification module card through the virtual channels which have the relation of combining to the user identification module card. The virtual channels which have the relation of combining to the user identification module card transfer the service requests so as to combine each user identification module card in a multi-card multi-standby mobile phone to a corresponding channel, avoiding the situation that when the intelligent phone transfers the service request, it is uncertain which channel is identified to transfer the service request and which user identification module card receives the transferred service request. | 01-26-2012 |
