20110274038 | METHOD AND APPARATUS FOR AVOIDING UNNECESSARY BEARER ESTABLISHMENT IN CIRCUIT SWITCHED FALLBACK - Methods and apparatuses are provided that facilitate avoiding establishment of unnecessary radio bearers in circuit switched fallback (CSFB). A CSFB procedure related to a device can be detected from receiving an extended service request or a forward relocation request, or from determining that an evolved packet system (EPS) is insufficient to handle a circuit switched voice call, and/or the like. Based at least in part on detecting the CSFB, establishment of radio bearers for inactive EPS bearers can be avoided. Where the device is in idle mode before CSFB, avoiding establishment of radio bearers can include avoiding establishment of all data radio bearers for the device. | 11-10-2011 |

The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network. | 07-26-2012 |
20130322302 | METHODS AND APPARATUS FOR UPDATING THE UE CAPABILITY IN AN E-UTRAN - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transmits a first set of capabilities to a first cell. The first set of capabilities is for communication with the first cell. The apparatus transmits information associated with a second set of capabilities to the first cell. The second set of capabilities is for communication with a second cell.

20140038622 | METHODS AND APPARATUS FOR EFFICIENT COMMUNICATION OF SMALL DATA AMOUNTS WHILE IN IDLE MODE - A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling communication of small data amounts while maintaining a RRC idle mode of operation for a UE. In an example, a UE is equipped to obtain a temporary radio bearer for communication of data, that meets one or more criteria for small data transmission, over a user plane in a UMTS or LTE based network, and transmit the data, over the user plane, using the temporary radio bearer while maintaining the UE in an RRC idle mode. A UTRAN entity may receive, over the temporary radio bearer assignment, the data from a UE in an idle mode, and send the data to a SGSN using a common small data connection. The SGSN may then send the data to a PGW. | 02-06-2014 |
20140056222 | SHARED CIRCUIT SWITCHED SECURITY CONTEXT - Certain aspects of the present disclosure provide a method for wireless communications. The method generally includes attempting, by a machine type communication (MTC) device, an attach procedure in order to detect a triggering request from an MTC server. | 02-27-2014 |

In one embodiment, the method may involve receiving an update location request from a mobile entity and forwarding the update location request to a subscriber data repository. The method may involve receiving a profile identifier from the subscriber data repository, the profile identifier corresponding to profile parameters for a subscription service for the mobile entity. The method may also involve accessing a lookup table to determine the profile parameters associated with the profile identifier, and determining whether to authorize the subscription service based at least in part on the profile parameters. | 06-12-2014 |

The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability. | 02-12-2015 |
20150056993 | CONNECTED MODE MOBILITY BETWEEN RADIO ACCESS NETWORKS - A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE. | 02-26-2015 |
