  • Patent number: 8619702
    Abstract: The radio node controller of one subnet sends a communication to an access terminal over a control channel through the infrastructure of another subnet. The radio node controller maintains an open traffic channel with an access terminal when the access terminal moves from a coverage area of the first subnet to a coverage area of the second subnet and when the access terminal uses a carrier in the first subnet that cannot be used in the second subnet. In a radio access network including a first and a second subnet, in which the first subnet includes both a first radio node controller and radio nodes that are configured in accordance with one 1xEV-DO standard and the second subnet includes radio nodes configured in accordance with another 1xEV-DO standard, the first radio node controller maintains an open traffic channel with an access terminal when the access terminal moves from the coverage area of the first subnet to the coverage area of the second subnet.

  • Patent number: 8620323
    Abstract: An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

  • Patent number: 8620322
    Abstract: A base station may decide to initiate a handover of a communication with a mobile station from a first wireless link to a new wireless link and identify one or more wireless links for the handover. For each identified wireless link, the base station may then determine a channel-quality metric, a wireless-link loading metric, and perhaps a coverage-area loading metric. In turn, the base station may then select the new wireless link based on the channel-quality metric and one or both of the wireless-link loading metric and the coverage-area loading metric. For example, the base station may apply a linear function that includes as variables the channel-quality metric and the wireless-link loading metric, and the base station may select the identified wireless link that best satisfies this function. The base station may then facilitate the handover of the communication from the first wireless link to the selected new wireless link.

  • Patent number: 8605636
    Abstract: Disclosed is a method capable of minimizing a period of time required for a handover network acquisition procedure when a handover occurs between communication networks which provide communication services using different mobile communication technologies. When a modem for a handover communication network performs network acquisition due to the occurrence of a handover, the modem previously extracts information about a handover channel from a Universal Handover Direction Message (UHDM), and uses the extracted channel information in a network acquisition procedure. Accordingly, the modem for a handover communication network can easily acquire a handover network even without using a preferred roaming list, and can omit an radio frequency (RF) tuning procedure by extracting a corresponding code division multiple access (CDMA) channel from the received UHDM, thereby reducing the total handover processing time period and increasing the success rate of the handover.

  • Patent number: 8594629
    Abstract: A method and system for processing failure of a handover to a CSG cell are provided, which are used to solve the technical problem of the interface signaling consumption and network performance degradation caused by the handover of a UE to a non-member CSG cell. When the UE is not an authorized subscriber of a target CSG cell, a core network notifies a source NodeB of the non-member failure information, thereby enforcing the UE to update an allowed CSG list to prevent the source NodeB or a source Radio Network Controller (RNC) or a source HNB from sending a handover required signaling to identical target cells, or prevents the UE from sending a handover request to identical target cells frequently by setting a delay timer, or the source NodeB or the source RNC or the source home NodeB prevents the UE from handing over to a neighboring CSG cell with identical CSG Identity (ID) under the condition of being able to acquire the CSG ID of the target CSG cell.
