  • Patent number: 7499703
    Abstract: Apparatus (48), and an associated method, for facilitating effectuation of control over when a mobile node (12) operable in a communication system (10) generates control signaling pursuant to a control procedure (62), such as a network search and selection procedure (64) or a registration procedure (66). A determiner (52) determines whether prior-sent control signals appear to have been successfully delivered to the network. If not, a selector (54) selects whether to increase a wait period prior to commencement of a subsequent control procedure, such as another network searching and selection procedure.
    Type: Grant
    Filed: February 11, 2004
    Date of Patent: March 3, 2009
    Assignee: Research In Motion Limited
    Inventors: Hongjun Zhang, Ashok C. Patel
  • Patent number: 7454220
    Abstract: Apparatus (48), and an associated method, for facilitating operation of a mobile node (12) operable in a communication system (10) to request allocation of communication capacity upon which to communicate data pursuant to a communication service. A channel allocation request generator (52) is selectably operable to generate requests for allocation of channel capacity upon which to communicate the data. A selector (54) selects when to cause the generator (52) to communicate the additional data packets. Selection is made to delay, or otherwise prevent, retransmission of requests, when a determination is made that the retransmission is unlikely to be successful.

  • Patent number: 7381547
    Abstract: Multiplex polymerase chain reaction assays for detecting a bacteria (e.g. Helicobacter pylori) in a specimen use multiple oligonucleotide primer pairs based on the sequences of multiple loci of the bacteria. In one application, up to five loci in the genomic DNA sequences of Helicobacter pylori were amplified. Two fragments of H. pylori were amplified from each locus, wherein a second fragment was an internal fragment of the first fragment.
