Abstract
A communication network has a first wireless access point (AP) in a first subnet segment and a second wireless AP in a second subnet segment, and provides a virtual local area network (VLAN) which spans the first and the second subnet segments. A mobile device associates with the first wireless AP using a first extended set service identifier (ESSID). In response to identifying a request to establish a communication session, the mobile device reassociates with the first wireless AP using a second ESSID, for accessing the VLAN to establish and maintain the communication session.
Claims17
A method for facilitating communication sessions for a mobile communication device in a communication network, the communication network having a first wireless access point in a first subnet segment and a second wireless access point in a second subnet segment, the method comprising:
- associating with the first wireless access point using a first extended set service identifier (ESSID);
- in response to identifying a request to establish a communication session involving the mobile communication device:
- reassociating with the first wireless access point using a second ESSID which is different from the first ESSID;
- establishing and maintaining the communication session for the mobile communication device while being associated with the first wireless access point using the second ESSID;
- and
- in a handoff to the second wireless access point during the communication session, associating with the second wireless access point using the second ESSID.
A computer program product, comprising:
- a non-transitory computer readable medium;
- computer instructions stored in the non-transitory computer readable medium;
- the computer instructions being executable by one or more processors of a mobile communication device for facilitating communication sessions for a mobile communication device in a communication network, the communication network having a first wireless access point in a first subnet segment and a second wireless access point in a second subnet segment, the computer instructions being further executable for:
- associating with the first wireless access point using a first extended set service identifier (ESSID);
- in response to identifying a request to establish a communication session involving the mobile communication device:
- reassociating with the first wireless access point using a second ESSID which is different from the first ESSID;
- establishing and maintaining the communication session for the mobile communication device while being associated with the first wireless access point using the second ESSID;
- and
- in a handoff to the second wireless access point during the communication session, associating with the second wireless access point using the second ESSID.
A mobile communication device configured to communicate in a wireless network which is part of a communication network, the communication network having a first wireless access point in a first subnet segment and a second wireless access point in a second subnet segment, the mobile communication device comprising:
- one or more processors;
- a wireless transceiver coupled to the one or more processors;
- the one or more processors being operative to:
- associate with the first wireless access point via the wireless transceiver using a first extended set service identifier (ESSID);
- identify a request to establish a communication session involving the mobile communication device;
- in response to the identifying:
- reassociate with the first wireless access point via the wireless transceiver using a second ESSID which is different from the first ESSID;
- establish and maintain the communication session via the wireless transceiver while being associated with the first wireless access point using the second ESSID;
- and
- in a handoff to the second wireless access point during the communication session, associate with the second wireless access point via the wireless transceiver using the second ESSID.
