20120093314 | Dynamic content-based ciphering on a control channel - In an exemplary embodiment content of a data message to be sent on a control channel is determined, and a selection is made between ciphering and not ciphering the data message based on the determined content. By example if from the content it is determined that that the data message is a SMS message, ciphering is selected and the control channel is a SACCH; else ciphering is not selected. Such a determination may be made by checking a service access point identifier for a data block comprising the data message. A data message within a data block received on the control channel is determined to be ciphered or not ciphered using only information within the data block, and the received data message is processed according to the determination. In another embodiment the FACCH is selected for sending the message if it is a SMS, and ciphering is selected for all data blocks sent on the FACCH. | 04-19-2012 |
20120213071 | Method and Apparatus for Channel Traffic Congestion Avoidance in a Mobile Communication System - An apparatus, comprising at least one processor configured to receive and read a series of blocks on a first channel and determine whether there is congestion and if not transmitting a channel request on a second channel. | 08-23-2012 |
20130130692 | MECHANISM TO UPDATE THE CSG CELL ACCESS CHECK UPON PLMN CHANGE AT HANDOVER - Solving dual errors for user equipment UE checking whether a private cell is allowed when handing over between serving and target cells, where the PLMN and/or EPLMNs list of the serving and target cells may differ. The serving cell may send a one-bit indication that there is a change in a handover command or system information SI6 message after which the UE may or may not refrain from reporting new cells until it performs a registration/location area update in the target cell. The target cell may trigger in the UE a registration update then provide the UE with the PLMN of the target cell. The serving cell can provide the PLMN of the target cell in a SI6 message or handover command, which the UE may use in place of or in addition to the PLMN/EPLMN of the serving cell when checking whether a private/closed subscriber group cell is allowed. | 05-23-2013 |
20140011500 | Method, Apparatus And Computer Program Product For Priority Based Cell Reselection In A Multi-RAT Environment - Systems and techniques for managing priorities are disclosed. A network sending broadcast and/or dedicated priorities to a mobile terminal may include priorities with respect to a radio access technology that does not support priority based reselection, such as for a legacy network that does not support priority based reselection. Priorities may be supplied to a mobile terminal to allow cell reselection decisions without using different cell reselection mechanisms in parallel. An indication of a plurality candidate cells with respect to cell reselection of a mobile terminal may be received and then a priority may be assigned to each candidate cells, where at least one candidate cell of the plurality of candidate cells does not support priority based cell reselection. The priorities may be provided to the mobile terminal. | 01-09-2014 |
20140198639 | Channel Traffic Congestion Avoidance in a Mobile Communication System - A mobile station detects whether there is congestion in a cell by monitoring a first channel fix downlink messages and decoding the messages to see if the decoded messages indicate congestion, where the first channel is a common control channel (CCCH). For the case in which the mobile station determines from the decoded messages that there is no congestion, the mobile station initiates a random access procedure by transmitting a request message uplink on a random access channel (RACH). Else for the case in which the mobile station determines from the decoded messages that there is congestion, the mobile station waits for a waiting time before initiating a random access procedure. | 07-17-2014 |
20150163698 | MECHANISM TO UPDATE THE CSG CELL ACCESS CHECK UPON PLMN CHANGE AT HANDOVER - Various combinations of these teachings solve dual errors for a user equipment UE checking whether a private cell is allowed when handing over between serving and target cells, where the PLMN and/or list of EPLMNs of the serving and target cells may differ. The serving cell may send a one-bit indication that there is a change in a handover command or a system information SI6 message after which the UE may or may not refrain from reporting new cells until it performs a registration/location area update in the target cell. The target cell may trigger in the UE a registration update then provide the UE with the PLMN of the target cell. The serving cell can provide the PLMN of the target cell in a SI6 message or handover command, which the UE may use in place of or in addition to the PLMN/EPLMN of the serving cell when checking whether a private/closed subscriber group cell is allowed. | 06-11-2015 |
