A private wireless network (104) and method are provided for facilitating communication between a private branch exchange (PBX) terminal (106) coupled thereto and a public wireless network (102) via an A-link (142). Generally, the private network (104) includes an A-interface (140) through which the PBX terminal (106) is coupled to the public network (102), and a virtual identity module that can be associated with the PBX terminal. Preferably, the module includes subscriber and security information for the PBX terminal (106). In one embodiment, the module comprises information stored in a memory system (100) coupled to the private network (104). Alternatively, the module comprises a card (150) held in a card holder/reader (152) in the private network (104). The public network (102) can be either a Global System for Mobile Communications (GSM) or a third-generation(3G) network. For a GSM network, the module is a virtual subscriber identity module (SIM). For a 3G network, the module is a virtual universal subscriber identity module (USIM).
A private wireless network for communicating with a public wireless network coupled thereto via an A-link, the private wireless network comprising at least one virtual identity module to enable a terminal of a private branch exchange (PBX) coupled to the private wireless network to communicate with the public wireless network via the A-link.
A communication system comprising:
In a communication system having a public wireless network, a private branch exchange (PBX) with a plurality of PBX terminals coupled thereto, and a private wireless network coupled to the public wireless network via an A-link and to the PBX, a method of enabling the plurality of PBX terminals to communicate with the public wireless network via the A-link, the method comprising steps of:
