Abstract: A source macro base station exchanges user data with a wireless communication device using an enhanced Radio Frequency (RF) service and receives RF measurement data from the wireless communication device. The RF measurement data is processed using a hysteresis parameter to detect a pico handover event to a target pico base station, and in response, determine if the target pico base station supports the enhanced RF service, and if the target pico base station does not support the enhanced RF service, the hysteresis parameter is modified to inhibit a pico handover to the target pico base station. The RF measurement data is processed to detect a macro handover event to a target macro base station, and in response, the hysteresis parameter is modified to drive a macro handover to the target macro base station if the target macro base station supports the enhanced RF service.

Abstract: Coordinated multipoint (CoMP) may involve coordination between multiple sectors to receive and/or process a given user equipment's uplink signal. Embodiments herein may help to intelligently select the particular sectors that should coordinate to provide uplink CoMP, based on the types of applications being served in sectors that are candidates to provide uplink CoMP. For example, a base station serving a primary sector in an CoMP group that includes two or more candidates from which to select a secondary sector sectors for uplink CoMP, may evaluate the application being served by traffic flows in these candidates, in an effort to select secondary sectors having lower-priority traffic flows.

Abstract: A mobility server receives a tracking area update from User Equipment (UE) indicating UE Identifier (ID) and current tracking area ID and responsively determines if the current tracking area ID is new tracking area ID. If current tracking area ID comprises new tracking area ID, then the mobility server updates a tracking area database with new tracking area ID. The mobility server translates UE ID and current tracking area ID into candidate Access Point Name (APN) data set and determines if candidate APN data set is a new APN data set. If candidate APN data set comprises new APN data set, then the mobility server transfers an instruction for UE to perform a wireless reattachment to obtain candidate APN data set and receives an attachment request from UE indicating UE ID and current tracking area ID and responsively transfers candidate APN data set to a data network gateway.

Abstract: In a wireless communication network, a network control system receives a request for a media session with a wireless communication device. The control system responsively determines if the wireless device is idle and determines if a source base station serving the wireless device can support the media session. If the wireless device is idle and the source base station does not support the media session, then the control system identifies a target base station to support the media session. The control system transfers a first redirect message for delivery to the wireless device through the source base station and transfers a second redirect message for delivery to the target base station. The redirect messages have session information for the media session. The target base station receives an acceptance of the media session from the wireless device and exchanges media for the media session responsive to the acceptance.

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.
