Internet protocol (IP) serverless page party (SPP) station and systems and methods for deploying multiple SPP stations
A serverless Page Party (SPP) station is provided for page announcing and party line conferencing that is configured to implement mutual provisioning to allow all SPP stations within a system to mutually maintain their configurations in runtime, and multiple master station negotiation and master failover. Plural SPP stations are connected with Ethernet cable or WIFi to a network and therefore without need for expensive and cumbersome cabling and daisy-chain configuration among stations. SPP stations route packets between each other via multicast technology and without need for a IP-PBX or other server (e.g., a SIP server) for controlling inter-station connections. In Mutual Provisioning Mode, SPP stations operate using a system configuration obtained from other SPP stations already on the network using a command channel. System configuration is maintained by a SPP station designated as a master station. Plural SPP stations can negotiate among themselves to designate a new master station.
1. A method performed by a processor for managing Internet Protocol (IP)-based stations connected via a network comprising:
configuring the IP-based stations to route packets between each other via multicast without a central device controlling inter-station communications between the IP-based stations by:
assigning multicast sockets to respective lines employed by the IP-based stations and chosen from one or more party lines and one or more page lines;
storing system configuration data at each of the IP-based stations; assigning a dedicated multicast address to common channel used by the IP-based stations to communicate with each other; and
updating the IP-based stations' configuration data based on communications via the common channel to allow the IP-based stations to automatically transmit on and listen to sockets based on their corresponding configuration data;
wherein the configuration data comprises a system designation identifying a system, and respective station identifiers for each of the IP-based stations deployed in that system; and
wherein the system configuration further comprises a group identifier for each of one or more groups of IP-based stations deployed in the system and designated ones of the station identifiers that are assigned to each group, each group having a corresponding group configuration comprising configurable fields that are used to configure each of the IP-based stations assigned to that group, and the system configuration comprises a profile for an IP-based station that comprises the system designation, a group number for the group to which the IP-based station is assigned, and the station identifier of the IP-based station.
2. The method of claim 1 , wherein the system configuration comprises different group configurations for respective group identifiers, each of the group configurations comprising allocations of multicast addresses that designate respective page sockets and respective party line sockets used by selected ones of the IP-based stations assigned to a corresponding one of the group identifiers.
3. The method of claim 1 , wherein the system configuration comprises a fixed IP address for the IP-based station.
4. The method of claim 1 , wherein the master station allocates an IP address to the IP-based station.
5. The method of claim 1 , wherein the inter-station communications between the IP-based stations comprises page announcing and party line conferencing between the IP-based stations.
