摘要： When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which 1×CSFB for communication of SMS messages in an LTE environment may be avoided. An IWS may receive a paging request message from a MSC, wherein the paging request message includes a first SMS service option indicating communication of a SMS message using a first RAT. The IWS may avoid an ESR procedure by analyzing the first SMS service option in the paging request message. Further the IWS may establish a common channel connection between the IWS and a target UE using a second RAT, wherein the first RAT and the second RAT are different.

摘要： Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.

摘要： Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.

摘要： A method enables a user equipment (UE) intervention to reduce a network-initiated Quality of Service (QoS) interruption time or a disruption of the network-initiated QoS, while avoiding application intervention. The method includes communicating with a source radio access network (RAN) in accordance with a network-initiated quality of service (QoS) profile. The method also includes transferring to a target RAN. The method further includes triggering, by a user equipment (UE), a QoS setup to reestablish the QoS profile.

摘要： Disclosed are systems, methods and computer program products for performing multiple registrations across different radio access technologies (RATs). In one aspect, the registration procedure provisions a mobile device to register with a primary RAT and pre-register with at least one non-primary RAT using its air interface, which is different from the primary RAT. The pre-registration procedure includes setting up a radio session context and a packet data network (PDN) context with the non-primary RAT. The procedure further includes setting up a pseudo-binding with an external PDN gateway and obtaining binding state information for the mobile device from the PDN gateway without transferring binding state from the primary RAT to the non-primary RAT. The binding state information may be added to the PDN context. The mobile device may then perform handoff from the primary RAN to non-primary RAN using the preset contexts.

摘要： Systems and methodologies are described that effectuate establishment of an IPSec tunnel for utilization in a wireless communication environment. IPSec establishment procedures on home base stations can be used to establish IPSec tunnels between home base stations situated on open access sectors of wireless communication environments and packet data interworking function components positioned at the contiguity of secured segments of the wireless communication environments. Moreover, high rate packet data point-to-point protocol challenge-handshake authentication protocols can be directed through the IPSec tunnels to facilitate authentication of access terminals associated with the home base stations in order to facilitate further communications with components dispersed within secure areas of wireless communication environments. Further, international mobile subscriber identities (IMSI) affiliated with access terminals associated with home base stations can be used to identify packet data serving nodes with which to establish communications between home base stations and packet data serving nodes.
