  • Patent number: 9629034
    Abstract: A method and system to help avoid a failed eCSFB call setup in the presence of handover. While a WCD is being served by a base station of a first network, the base station may detect both a fallback trigger and a handover trigger. The fallback trigger may be a trigger to initiate a fallback setup procedure, where the fallback setup procedure involves execution of a sequence of steps including a particular step. The handover trigger may be a trigger to initiate a handover procedure. The base station determines that the handover trigger was detected before execution of the particular step of the fallback setup procedure. Responsive to determining that the handover trigger was detected before execution of the particular step, the base station (a) foregoes the fallback setup procedure and (b) transmits to the WCD a message directing the WCD to establish communication with the second network.

  • Patent number: 9578640
    Abstract: Disclosed is a method and corresponding apparatus to make use of hybrid-ARQ repetition factors as a way to differentiate service quality to various mobile terminals. Depending on a mobile terminal's subscription service class, such as the mobile terminal's PLMN, the mobile terminal may be made to use a particular hybrid-ARQ repetition factor. For instance, a mobile terminal of a high service class may be made to use a low hybrid-ARQ repetition factor, which may help the mobile terminal experience less downlink transmission delay and thus a higher downlink data rate. Whereas, a mobile terminal of a low service class may be made to use a high hybrid-ARQ repetition factor, which may cause the mobile terminal to experience more downlink transmission delay and thus a lower downlink data rate, and may further free up downlink transmission resources to facilitate better service for other mobile terminals.

  • Patent number: 9560666
    Abstract: As disclosed, while a wireless communication device (WCD) is idling on a particular carrier frequency of a base station, the base station may receive a message broadcast by that base station, the message specifying multiple relative sets of priority levels defined for a set of carrier frequencies and correlating each of the multiple relative sets of priority levels with respective different WCD operational characteristics. In particular, the message may specify a first correlation of one relative set of priority levels with one WCD operational characteristic and includes a second correlation of a different relative set of priority levels with a different WCD operational characteristic. The WCD may select one of the relative sets of priority levels responsive to the WCD having a WCD operational characteristic that the message correlates with the selected relative set of priority levels. The WCD may then apply the selected relative set of priority levels.

  • Patent number: 9560660
    Abstract: Disclosed is a method and system of managing an allocation of resources in a wireless communication system. According to the disclosure, a base station may receive or otherwise determine an indication of radio frequency (RF) conditions being perceived by a given user equipment device (UE). Based on that indication, the base station may make a decision of whether to use a first resource limitation or a second resource limitation for data transmissions to the given UE, where the second resource limitation generally allows for a lesser extent of resources to be allocated than the first resource limitation in weaker RF conditions. For instance, the base station may decide to use a bit-rate limitation for threshold strong RF conditions and a resource-block limitation for threshold weak RF conditions. Thereafter, the base station may allocate resources for a data transmission to the given UE in accordance with the decision.

  • Patent number: 9544875
    Abstract: Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.

  • Patent number: 9544829
    Abstract: A network node receives from a mobile terminal being served by a first coverage area a measurement report indicating signal level of a second coverage area detected by the mobile terminal. The network node then makes a determination, by considering PLMNs of the mobile terminal and of the coverage areas, of (i) whether the mobile node is a home mobile node of the first coverage area and (ii) whether the mobile node is a home mobile node of the second coverage area. Based on that determination, the network node then selects a handoff threshold. And based on the handoff threshold and the reported signal level, the network node decides whether to trigger handoff of the mobile terminal from the first coverage area to the second coverage area. The network node then triggers the handoff if the decision is to do so.

  • Patent number: 9473976
    Abstract: When a UE engages in application-layer session setup signaling with a session server via a radio access network and gateway, the UE conveys in its session setup signaling an indication of the UE's observed air interface quality (e.g., received signal strength or signal to noise ratio) and perhaps an indication of a characteristic of an neighboring air interface (e.g., a duplex configuration or band of the neighboring air interface). The session server then reports the UE's indicated air interface quality and perhaps neighboring air interface characteristic to a policy server, and the policy server uses that information as a basis to select a quality of service level for a bearer to be established between the UE and the gateway for carrying media content of the session. The policy server then invokes establishment of a bearer having the selected quality of service level.

  • Patent number: 9468039
    Abstract: A multi-mode mobile station is able to communicate with a first system using a first air interface protocol (e.g., EVDO) and with a second system using a second air interface protocol (e.g., 1×RTT CDMA). When the first system schedules a page message for transmission to the multi-mode mobile station, the first system may query the second system to determine whether the second air interface protocol is being used for a current call involving the multi-mode mobile station or is being used to attempt establishment of a requested call to the multi-mode mobile station. In the case of a current call, the first system may wait until the call is released before transmitting the page message. In the case of an attempt to establish a requested call, the first system may wait to determine whether the attempt is successful before transmitting the page message.

  • Patent number: 9445332
    Abstract: A method and apparatus for improved idle handoff a mobile station in a wireless communication system. While idling in a particular sector of the system, the mobile station will select a target sector based on a determination that the target sector has the same number of channels as the current sector, such as the same number of paging channels and perhaps the same number of frequency channels as the current sector. The mobile station will then engage in an idle handoff from the current sector to the selected target sector. By striving to hand off to a sector that has the same number of channels, particularly the same number of paging channels, the mobile station may avoid having to hash onto a channel in the target sector and may thereby minimize the likelihood of missing a page message sent while the mobile station was busy hashing onto the channel.

  • Patent number: 9426828
    Abstract: A base station may provide wireless service on an air interface that defines different mutually exclusive groups of random access channel (RACH) instances for different uses. In one example, the air interface may define a first group of RACH instances having groupings of preambles for designating a value of a characteristic, and define a second group of RACH instances that does not have groupings of preambles. As another example, the air interface may define a first group of RACH instances that has groupings of preambles for designating a value of a first characteristic, and define a second group of RACH instances that has groupings of preambles for designating a value of a second characteristic. The base station may then differentially handle random access requests based on whether the base station receives a preamble in a RACH instance of the first group or rather the second group.
