20120026903 | SELECTIVE ALLOCATION OF DEDICATED CHANNEL (DCH) RESOURCES WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a UE determines to transmit a message (e.g., an alert message, a call initiation message). Based on the type of the message to be transmitted, the UE selectively transmits supplemental data configured to prompt an access network to transition the UE to a dedicated channel state (DCS). In another embodiment, an application server configured to arbitrate communication sessions between UEs receives a message for transmission to a target UE. Based on the type of the message to be transmitted to the target UE, the application server selectively transmits, to a serving access network of the target UE, supplemental data configured to prompt the serving access network to transition the target UE to the DCS. In another embodiment, the access network selectively transitions a target UE to the DCS based on whether differently sized messages are received at the access network for transmission to the target UE. | 02-02-2012 |
20120113862 | COMMUNICATING VIA A FEMTO ACCESS POINT WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a user of a wireless communications device (WCD) is notified when operating in a serving area of a FEMTO access point (AP). In another embodiment, the WCD can notify an application server (AS) that the WCD is served by the FEMTO AP. In another embodiment, the AS can set a service level for a server-arbitrated communication session (CS) based on the FEMTO AP serving status of participating WCDs. In another embodiment, the FEMTO AP can determine to use a downlink control or signaling channel to transmit data to the WCD. In another embodiment, based on its serving FEMTO AP status, the WCD can (i) modify its participation level in the CS and/or (ii) selectively track usage. In another embodiment, the WCD or FEMTO AP can measure performance parameters of the CS to determine whether to trigger a handoff of the WCD to a different AP. | 05-10-2012 |

20130121313 | ADJUSTING A BUNDLING FACTOR FOR A COMMUNICATION SESSION BASED ON WHETHER AN ACCESS NETWORK SUPPORTS HEADER COMPRESSION AND DYNAMICALLY SETTING A DE-JITTER BUFFER SIZE BASED ON A BUNDLING FACTOR - In an embodiment, a user equipment (UE) determines to originate a communication session, and the UE further determines whether an access network serving the UE supports header compression. Based on the header compression determination, the UE establishes on a given bundling factor (BF). The UE transmits a first set of media packets to a server during the communication session, the first set of media packets each including a first number of media frames based on the given BF. The server determines target BF(s) for target UE(s) and determines whether to modify the given BF based on the target BF(s). Based on these determinations, the server transmits a second set of media packets either unmodified from the first stream of data packets, or modified based on the target BF(s). The target UE(s) receive the second stream of data packets and set a de-jitter buffer size based on the associated BF. | 05-16-2013 |
20130182586 | OBTAINING COMMUNICATION SESSION INITIATION INFORMATION IN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a user equipment (UE) receives request to set-up a communication session of a given type while the UE is in a dormant state (e.g., URA_PCH or CELL_PCH). The UE configures a state transition request message (e.g., a cell update message) (i) to request that an access network transition the UE from the dormant state to a target state (e.g., CELL_FACH or CELL_DCH) and to obtain a network-assigned serving cell-specific identifier (e.g., C-RNTI) for exchanging data between the UE and the serving cell in association with the communication session of the given type and (ii) to indicate the given type of the communication session. The UE transmits the state transition request message to the access network, and the access network determines the given type of the communication session based on the state transition request message. | 07-18-2013 |
20130315181 | SELECTIVE ALLOCATION OF DEDICATED CHANNEL (DCH) RESOURCES WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a UE determines to transmit a message (e.g., an alert message, a call initiation message). Based on the type of the message to be transmitted, the UE selectively transmits supplemental data configured to prompt an access network to transition the UE to a dedicated channel state (DCS). In another embodiment, an application server configured to arbitrate communication sessions between UEs receives a message for transmission to a target UE. Based on the type of the message to be transmitted to the target UE, the application server selectively transmits, to a serving access network of the target UE, supplemental data configured to prompt the serving access network to transition the target UE to the DCS. In another embodiment, the access network selectively transitions a target UE to the DCS based on whether differently sized messages are received at the access network for transmission to the target UE. | 11-28-2013 |
20140064070 | OPTIMISTIC QUALITY OF SERVICE SET UP - The disclosure relates to optimistic QoS setup. A network element receives an IP packet that is not associated with a QoS request on a bearer for an application/service executing on a target client device, and initiates QoS activation for the target client device based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service. A server receives a session setup request that is not associated with a QoS request for an application/service executing on a target client device, the session setup request identifying one or more client devices to participate in a session, and initiates QoS activation for at least one of the client devices, before a session announcement is transmitted to the client devices, based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service. | 03-06-2014 |
20140064071 | DIRECTIONAL ADJUSTMENT TO QUALITY OF SERVICE BASED ON MONITORED TRAFFIC ACTIVITY ON A LINK - In an embodiment, an apparatus monitors traffic usage in uplink and downlink directions of a link that is configured to support a communication session for the client device. The apparatus can correspond to a core network component or to an access network component. The apparatus initiates, in association with the communication session, (i) an uplink-specific QoS adjustment to a first level of QoS assigned to the uplink direction of the link based on the monitored traffic usage in the uplink direction, and/or (ii) a downlink-specific QoS adjustment to a second level of QoS assigned to the downlink direction of the link based on the monitored traffic usage in the downlink direction. The link is maintained in both the downlink and uplink directions throughout the communication session irrespective of any QoS adjustments in the uplink and/or downlink directions of the link that occur during the communication session. | 03-06-2014 |
20140064084 | DIRECTIONAL ADJUSTMENT TO QUALITY OF SERVICE BASED ON PREDICTED TRAFFIC ACTIVITY ON A LINK - In an embodiment, an apparatus predicts traffic usage in uplink and downlink directions of a link that is configured to support a communication session for the client device. In an example, the predictions can be based upon a call state parameter (e.g., if the client device is a non-floorholder or is muted the client device is unlikely to send much traffic in the uplink direction, etc.). The apparatus initiates, in association with the communication session, (i) an uplink-specific QoS adjustment to a first level of Quality of Service (QoS) assigned to the uplink direction of the link based on the predicted traffic usage in the uplink direction, and/or (ii) a downlink-specific QoS adjustment to a second level of QoS assigned to the downlink direction of the link based on the predicted traffic usage in the downlink direction. The apparatus can correspond to the client device or alternatively to a server. | 03-06-2014 |
20140064124 | MANAGING GUARANTEED BIT RATE QUALITY OF SERVICE RESOURCE ALLOCATION BASED ON GUARANTEED BIT RATE DATA ACTIVITY ON A LINK - In an embodiment, an apparatus (e.g., a client device, an eNodeB, MME, S-GW, P-GW, UTRAN component, etc.) detects a first transition of a client device from an active state to an idle state while the client device is allocated a Quality of Service (QoS) link by a serving network. The apparatus caches QoS information associated with the QoS link, and releases the QoS link in response to the detection of the first transition. The apparatus later detects, after the caching and releasing, a second transition of the client device from the idle state back to the active state. The apparatus re-establishes the QoS link in response to the detection of the second transition using the cached QoS information. | 03-06-2014 |
20140064156 | SELECTIVE NETWORK PARAMETER CONFIGURATONS BASED ON NETWORK IDENTIFICATION OF NON-IMS MULTIMEDIA APPLICATIONS - In a first embodiment, an access network detects whether QoS links for both IMS and non-IMS sessions are allocated to a client device, whereby the non-IMS session is recognized as being associated with a particular application type. An SRVCC feature for the IMS session is disabled if the QoS link for the non-IMS session exists and carries at least a threshold level of traffic. In a second embodiment, a non-IMS session is supported by a first network with QoS and is then handed off to a second network. After the handoff, the second network supports the non-IMS session with an application-specific QoS configuration based on application-identifying information provided from the first network. In a third embodiment, a single or dual-transceiver client device is engaged in a non-IMS session with QoS. A page originating from a CS network is ignored if a do-not-disturb feature is activated for the non-IMS session. | 03-06-2014 |
20140064209 | OPTIMIZED ALWAYS-ON WIRELESS SERVICE USING NETWORK ASSISTANCE AND KEEP-ALIVES - The disclosure generally relates to optimized always-on wireless service using network assistance and keep-alives. More particularly, in response to a user equipment (UE) requesting a bearer for an always-on service, a network may establish the bearer for the always-on service and transmit an availability time that indicates a period during which the bearer will be held in an active state to the UE. Any applications running on the UE may then use the bearer for the always-on service, and the UE may transmit a single keep-alive message to the network before the availability time expires to reset the period during which the bearer will be held in the active state. Furthermore, the keep-alive message may be structured to not generate a reply and thereby reduce battery consumption, reduce communication overhead, and improve network capacity | 03-06-2014 |
20140064210 | SELECTIVELY ALLOCATING QUALITY OF SERVICE TO SUPPORT MULTIPLE CONCURRENT SESSIONS FOR A CLIENT DEVICE - In an embodiment, a server mediates a first group communication session with the user equipment (UE) by exchanging media for the first group communication session with the UE over a first link with a first level of Quality of Service (QoS) resources (e.g., either without a guaranteed bit rate (GBR) or a threshold amount of GBR) and exchanging non-media signaling data for the first group communication session with the UE over a signaling link that is either the same or separate from the first link. The server detects, while the UE continues participation in the first group communication session, that the UE has joined or is attempting to join a second group communication session. The server applies a policy for selectively allocating additional QoS resources to supplement the first level of QoS resources to the UE for concurrently supporting both the first and second group communication sessions in response to the detection. | 03-06-2014 |
20140066082 | PROVIDING GROUP CALL PRIORITY ACCESS IN LTE AND PRIORITY ACCESS FOR USER EQUIPMENTS WITH DUAL ACCESS CLASSES - The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification. | 03-06-2014 |
20140066084 | PROVIDING SERVICE BASED ON QUALITY OF SERVICE RESOURCES IN A LONG TERM EVOLUTION COMMUNICATIONS SYSTEM - In an embodiment, an apparatus (e.g., a client device or a server) sends, to a Long Term Evolution (LTE) network component, a request to setup a Quality of Service (QoS) bearer with a threshold level of QoS to support the communication session for the client device. The apparatus permits the client device to proceed with the attempt to setup the communication session irrespective of whether the LTE network component grants the threshold level of QoS for the QoS bearer. In another embodiment, the LTE network component rejects an initial QoS request from the apparatus due to QoS unavailability, and then receives another QoS request within a threshold period of time. Based on the two (or more) QoS requests being received within the threshold period of time, the LTE network component allocates an available level of QoS to the client device that is less than the requested level of QoS. | 03-06-2014 |
20140068064 | METHOD FOR QOS MANAGEMENT IN HOME AND ROAMING SCENARIOS BASED ON LOCATION/APP SERVER ASSISTANCE - The disclosure is related to managing, at an application server, a quality of service (QoS) provided for an application executing on a client device. An aspect receives, from the client device, an identifier of a first network servicing the client device, determines a QoS of a supplemental link established by a second network for the application, determines whether or not the QoS of the supplemental link meets requirements of the application, and determines whether or not the first network is able to support an alternative acceptable QoS when the QoS of the supplemental link does not meet the requirements of the application. | 03-06-2014 |
20140068098 | REDUCING NETWORK LATENCY RESULTING FROM NON-ACCESS STRATUM (NAS) AUTHENTICATION FOR HIGH PERFORMANCE CONTENT APPLICATIONS - Aspects relating to reducing network latency in systems that use NAS Authentication/Security procedures are disclosed. For example, a method for reducing latency due to NAS authentication can include determining a number (n) or time (t) of service requests from an idle state that trigger a NAS authentication. A penultimate service request is detected before the nth service request or after time (t). A gratuitous service request is sent after the penultimate service request. | 03-06-2014 |
20140078898 | HANDING OFF BETWEEN NETWORKS WITH DIFFERENT RADIO ACCESS TECHNOLOGIES DURING A COMMUNICATION SESSION THAT IS ALLOCATED QUALITY OF SERVICE - In an embodiment, a UE performs an IRAT handoff from a source network with a first RAT to a target network with a second RAT, and obtains a channel from the target network. The UE reports a level of QoS on the channel to a server via the target network. The server issues instructions to the UE and/or the target network for modifying the level of QoS in response to the report based on if the level of QoS is insufficient to support a particular type of communication session. In another embodiment, in conjunction with an IRAT handoff, the source network sends a handoff preparation message to the target network to facilitate the target network to initiate setup of a set of channels with a non-IMS application-specific QoS configuration for the UE on the target network in conjunction with the handoff. | 03-20-2014 |
20140219167 | QUALITY OF SERVICE FOR WEB CLIENT BASED SESSIONS - The disclosure generally relates to network-initiated and client-initiated mechanisms to enable quality of service (QoS) for web-based client applications that may high efficiency, high performance, or otherwise guaranteed service levels. For example, to enable QoS for calls or other sessions associated a web-based application, one or more signaling messages may be exchanged between a server and a first user equipment (UE) to establish a call between the first UE and a second UE and to establish a peer connection between the server and at least the first UE. As such, QoS may be activated for at least the peer connection between the first UE and the server, wherein the server may route data associated with the web-based application between the first UE and the second UE over the established peer connection to implement the activated QoS. | 08-07-2014 |
