US 9,520,968 B2 · Method for performing seamless transmission control with aid of request carrying fragment ID, and associated apparatus

Abstract

A method for performing seamless transmission control for an electronic device and an associated apparatus are provided, where the method includes the steps of: sending a request frame carrying a fragment identification (ID) to trigger a responder in a wireless network system to initiate retransmission corresponding to the fragment ID, wherein the fragment ID indicates beginning of a remaining portion within a plurality of fragments of data being sent from the responder to the electronic device; and receiving at least one response frame sent from the responder, for utilizing the remaining portion within the plurality of fragments of the data, wherein the remaining portion within the plurality of fragments of the data is obtained from the at least one response frame.

Dependent claims

A method for performing seamless transmission control for an electronic device in a wireless network system, wherein the electronic device sends a first Initial Request for Generic Advertisement Service (GAS) data to an Access Point (AP), and when a first response of the first Initial Request is received from the AP, data transmission between the AP and the electronic device is initiated such that fragments of GAS data are sent from the AP to the electronic device in response to respective Comeback Requests sent from the electronic device, the method comprising the steps of:

sending a Comeback Request to the AP for a fragment of GAS data;
starting a timer;
sending a second Initial Request to the AP when timeout is reached before the fragment of GAS data is received from the AP, wherein the second Initial request carries a fragment ID corresponding to the fragment of GAS data;
receiving a second response from the AP;
and
re-initiating transmission between the AP and the electronic device such that fragments of GAS data are sent from the AP to the electronic device beginning with the fragment of GAS data.

3 more elements

An apparatus for performing seamless transmission control for an electronic device in a wireless network system, the apparatus comprises at least one portion of the electronic device, the apparatus comprising:

a transceiver arranged to transmit information to an Access Point (AP) or receive information from the AP for the electronic device;
and
a processing circuit, coupled to the transceiver, arranged to control operations of the electronic device, wherein when the processing circuit sends, with the transceiver, a first Initial Request for Generic Advertisement Service (GAS) data to an Access Point (AP), and a first response of the first Initial Request is received from the AP, data transmission between the AP and the electronic device is initiated such that fragments of GAS data are sent from the AP to the electronic device in response to respective Comeback Requests sent from the electronic device, when a Comeback Request for a fragment of GAS data is sent, a timer is started and timeout is reached before the fragment of GAS data is received from the AP, the processing circuit sends, with the transceiver, a second Initial request to the AP, wherein the second Initial request carries a fragment ID corresponding to the fragment of GAS data, the processing circuit further receives a second response sent from the AP and re-initiates transmission between the AP and the electronic device such that fragments of GAS data are sent from the AP to the electronic device beginning with the fragment of GAS data.
