  • Patent number: 8509801
    Abstract: An extended global service redirection message (EGSRDM) is provided within the standards for mobile communications networks, where the EGSRDM supports multiple band class records within the common fields. The base station generates an EGSRDM with multiple band class records, with each band class assigned specific frequencies. When a mobile station (MS) receives the EGSRDM, the MS compares the parameters of the various band classes (frequency, ACCOLC, P_Rev) with those supported by the MS, and generates a list of the band class(es) from those provided within the EGSRDM that are supported by that MS. The MS then selects the first band class within the list and selects a frequency within the selected band class to assign to MS communication. When none of the frequencies within the selected band class is available, the MS selects the next band class within the created list and selects a frequency from the next band class.

  • Patent number: 7787413
    Abstract: An apparatus, a method, and a computer program are provided for increasing the efficiency of Radio Frequency (RF) resources. Specifically, a modified Resource Release Request Message (RRRM) is utilized. The modified RRRM incorporates several additional fields that allow for the release of multiple service instances at approximately the same time. The simultaneous or near simultaneous release of multiple service instance is more efficient that the traditional RRRM for the release of a single service instance. Therefore, limited RF resources can be better preserved.

  • Patent number: 7460515
    Abstract: A packet data service node (PDSN) is formed to establish a connection with a plurality of mobile terminals by way of one or more packet control function cards or devices. A packet control function (PCF) card or device is formed to provide an interface between the packet data domain and wireless domain and further to inform a base station controller/access network controller (BSC/ANC) to block the setup and establishment of any additional communication links in a specified manner until the overload condition ceases to exist. More specifically, the PCF receives loading information from each PDSN to which it is connected and determines a composite loading factor. The PCF transmits the composite loading factor to the BSC/ANC periodically or if the loading factor exceeds a specified threshold and call blocking should be initiated for packet data calls for a select group of mobile terminals.

  • Patent number: 7457321
    Abstract: The present invention supports a message protocol on a wireless communication network to setup a shortened slot cycle operation for a mobile station. During wireless, packet-based communication, a mobile station can utilize a shortened slot cycle to increase the frequency a communication channel is monitored by a mobile station while in idle state. While this is advantageous to communication requiring a fast response, it increases power consumption and decreases battery charge time. Under present usage, the shortened slot cycle must be used by all mobile stations connected to the base transceiver whether required or not. To increase efficiency and avoid unnecessary power consumption, the invention allows only those mobile stations that require it to implement the shortened slot cycle. Signaling messages sent from the mobile station to the base station controller will initiate a shortened slot cycle only for that mobile station.
