摘要： A method (800, 900) and apparatus (1001) for controlling a session between communication units (141-146) sharing a group Internet Protocol (IP) multicast address. The method includes determining communication units from which a response to a session initiation protocol (SIP) control message is not required and preparing the control message which is sent to the communication units using the group address with information used to control from which of the of communication units the response is required. The SIP control message is sent to a second communication unit using a unicast address indicating that the response is required.

摘要： A dual-band wireless subscriber unit (SU) (112) having an enterprise address of E1 and a cellular address of C1, corresponding method (200), software program (310-320), and WLAN (104) determines (202) that the SU is about to leave a wireless local area network (WLAN) (104). In response, when the SU is involved in a call on E1, the SU sends (212, 208) to the WLAN a SIP message, for example a Refer message with a “Refer To” field of C1 if an ongoing call or a SIP Redirect message with a contact address of C1 if a new call is attempting to begin on E1. In response to receiving either message, the WLAN seamlessly transfers (210, 214) the call to C1.

摘要： A communication unit (CU) (109, 111) network controller (113) and corresponding methods (603-609) are described that facilitate selectively routing calls. The CU includes a transceiver (403) suitable to support an air interface with a local area network (LAN) (101) and with a wide area network (WAN) (105) and a controller (405) that is coupled to and controlling the transceiver. These are each and collectively configured to determine when a bearer leg within the WLAN will not support a call attempt over the bearer leg and responsive to so determining, initiate the call over another bearer leg, e.g. within the LAN or the WAN. The determining includes, for example, receiving a message (703, 707, 713) that indicates or implies that the call can not be supported.

摘要： A high availability network mechanism (100) is provided having a primary node (105) and at least one secondary node (120) utilizing Virtual Router Redundancy Protocol (“VRRP”) compatible redundancy systems. The primary and secondary nodes (105 and 120) are associated with access routers (110 and 130, respectively) that are associated with edge routers (115 and 130, respectively). A virtual IP address is associated with the primary node (105) with a first cost assigned to the primary node (105). The same virtual IP address is associated with the secondary node (120) with a second cost assigned to the secondary node (120). A core IP network (135) utilizing an Open Shortest Path First (“OSPF”) compatible redundancy system is accessible through the edge routers (115 and 130) such that the primary and secondary nodes (105 and 120) advertise the virtual IP address with different costs on the IP network (135).
