20090221250 | METHODS AND APPARATUS FOR HANDLING A SIGNALING MESSAGE THE RELATES TO TRANSMISSION RATE RESTRICTIONS - A method for handling a signaling message that specifies transmission rate restrictions may include operating in a first state. The method may also include receiving the signaling message from a network. The signaling message may include an activation time, the transmission rate restrictions and the control duration. The method may also include receiving a state transition trigger to operate in a second state. The method may also include determining the user equipment's behavior regarding the transmission rate restrictions upon receiving the state transition trigger. | 09-03-2009 |
20110312299 | Methods and apparatuses facilitating synchronization of security configurations - Methods and apparatuses are provided for synchronizing security parameters between access terminals and a wireless network. An access terminal and network entity can conduct a security mode procedure where the access terminal sends a security mode complete message to the network entity. On receipt of the security mode complete message, the network entity may update to new security parameters. The access terminal may initiate a mobility procedure while the security mode procedure is ongoing and may, as a result, abort the security mode procedure and revert back to the old security parameters. The access terminal can send a mobility update message to the network entity including a dedicated status indicator adapted to inform the network entity that the access terminal has reverted back to the old security parameters. In response to the mobility update message, the network entity may revert back to the old security parameters. | 12-22-2011 |
20120020393 | USER DEVICE DORMANCY - In a particular embodiment, a method includes sending a message from a communication device to a radio network controller. The message indicates that a data session has ended. The data session is supported by a wireless channel between the communication device and the radio network controller. After a time period following the sending of the message, a second message is selectively sent to the radio network controller. The second message indicates that the data session has ended. The second message is selectively sent based at least in part on whether a measurement indicates that data was communicated via the wireless channel during the time period. | 01-26-2012 |
20120087239 | METHODS AND APPARATUS FOR HANDLING A SIGNALING MESSAGE THAT RELATES TO TRANSMISSION RATE RESTRICTIONS - A method for handling a signaling message that specifies transmission rate restrictions may include operating in a first state. The method may also include receiving the signaling message from a network. The signaling message may include an activation time, the transmission rate restrictions and the control duration. The method may also include receiving a state transition trigger to operate in a second state. The method may also include determining the user equipment's behavior regarding the transmission rate restrictions upon receiving the state transition trigger. | 04-12-2012 |
20120178402 | Optimized Limited Service Acquisition in a Multiple Subscription Device - Mobile devices, such as a dual standby global phone, can have multiple subscriptions to access different radio access technologies, such as Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) technologies. A selective scanning utility recognizes that emergency calls can be processed in any active subscription rather than being independently invoked to obtain a plurality of ways to make an emergency call. The utility limits service acquisition to just one of all active subscriptions in device, thereby achieving the objective of staying camped for limited service without needing to perform cell selection on emergency call origination on a secondary subscription at the cost of battery service. For single-radio devices, this solution also increases the availability of the first selected cell by avoiding the need to tune away for cell selection on the secondary subscription. | 07-12-2012 |
20120190362 | MOBILE DEVICE REQUESTS OF NON-COMMUNICATION TIME PERIODS TO A WIRELESS COMMUNICATION NETWORK - A particular method includes sending a request from a mobile device associated with a plurality of subscriptions to a wireless communication network. The request indicates a time period requested by the mobile device as a non-communication time period of the wireless communication network with respect to the mobile device. | 07-26-2012 |
20120264425 | SELECTIVE BAND-SCANNING BY A MULTI-SIM USER EQUIPMENT (UE) IN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a wireless communications device (WCD) is provisioned with a plurality of subscriber identity modules (SIMs). The WCD determines a first set of bands (BAND | 10-18-2012 |
20130016601 | APPARATUS AND METHOD FOR MAINTAINING A CIRCUIT-SWITCHED VOICE CALL IN A MULTI-RAB WIRELESS COMMUNICATION SYSTEM IN AN AREA OF WEAK COVERAGE - An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call. | 01-17-2013 |
20130090137 | APPARATUS AND METHODS FOR REDUCING PAGE LOSS IN MULTIPLE SUBSCRIPTION, MULTIPLE RADIO ACCESS TECHNOLOGY DEVICES - Disclosed are methods and apparatus for reducing page loss in a multiple subscription, multiple radio access wireless device, such as a dual SIM wireless device. The disclosed methodology and apparatus determine whether a conflict will arise between paging channel information received from at least two or more subscriptions from two or more radio access networks using a single receiver in the wireless device. The reception for paging channel information via the wireless receiver is switched to receive the paging channel information from a neighboring cell for one of the two subscriptions when a conflict is determined. By switching reception of paging channel information to another neighboring cell, the likelihood of page collisions between two subscriptions is reduced. | 04-11-2013 |
20130303240 | METHODS AND APPARATUSES FOR OPTIMIZATION OF MULTIPLE SUBSCRIPTION DEVICE PERFORMANCE - Methods and apparatus of tune away in wireless communications include receiving a master information block (MIB) from a first subscription network entity on a first subscription in a user equipment (UE). The method further includes determining system information block (SIB) scheduling information associated with the first subscription network entity. Moreover, the method includes tuning away from the first subscription to a second subscription. | 11-14-2013 |
20150057046 | System and Methods for improving Page Decode Performance During Reading of System Information on a Multi-SIM Wireless Communication Device - Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap. | 02-26-2015 |
