Abstract
A method and system for enabling a first communication device to communicate with a second communication device. The first communication device is in a first network. The second communication device is in a second network. The second communication device has network connectivity only in its home network. When a first call for the second communication device is received from the first communication device, roaming on the second communication device is enabled and the location of the second communication device is determined. After determining the location of the second communication device, the first call is routed to the second communication device.
Claims29
A method for enabling a first communication device to communicate with a second communication device, the first communication device being in a first network, the second communication device being in a second network, the second communication device having connectivity within the home network of the second communication device only, the method comprising the steps of:
- a. receiving a first call from the first communication device for communicating with the second communication device;
- b. enabling roaming on the second communication device, wherein the roaming is enabled on receiving the first call from the first communication device;
- c. locating the second communication device;
- and
- d. executing the first call.
A method for enabling a first communication device to communicate with a second communication device, the first communication device being in a first network, the second communication device being in a second network, the second communication device having connectivity within home network of the second communication device only, the method comprising the steps of:
- a. receiving a first call from the first communication device for communicating with the second communication device, the first call being made by using a feature code and connection number of the second communication device;
- b. enabling roaming on the second communication device after receiving the first call from the first communication device;
- c. locating the second communication device;
- and
- d. executing the first call.
A mobile communication network suitable for enabling a first communication device to communicate with a second communication device, the mobile communication network comprising a plurality of mobile switching centers, each mobile switching center comprising:
- a. a call processing module, the call processing module processing a first call;
- b. a requesting module, the requesting module requesting the home location register of the second communication device to enable roaming on the second communication device;
- c. a message exchange module;
- and
- d. a location determining module, the location determining module determining the location of the second communication device.
