An exemplary method of facilitating hand-offs between Femtocells includes receiving an indication of a cell identifying code detected by a mobile station currently communicating with a serving Femtocell. A determination is made whether the received cell identifying code corresponds to a known Femtocell. The known Femtocell becomes a target Femtocell if a successful hand-off was previously made from the serving Femtocell to the known Femtocell. A hand-off is instigated to the target Femtocell.

Femtocell hand-offs

Example embodiments provide a method and/or network element capable of mitigating one or more effects of operating at full capacity. According to an example embodiment, a network element may address load capacity by identifying that a first network element (e.g., a femto) is operating at a threshold capacity. If a communication from a second network element intended for the first network element is received, an operation is performed that informs the second network element of at least one of (i) that the first network element is operating at a threshold capacity and (ii) that the communication cannot be delivered to the first network element while the first network element is operating at a threshold capacity.

A method for wireless communications with mobile stations located within a femtocell is described. The method includes registering a femtocell with an IMS core network to receive IMS services for one or more mobile stations located within the femtocell, and separately registering the mobile station with an application server to provide additional services to the mobile station located within the femtocell. The additional services may be CDMA services. Also, registering the femtocell with the IMS core network may include transmitting femtocell registration information that does not include information regarding the mobile station to the IMS core network to request IMS services for the mobile station.

Methods for provisioning mobile stations and wireless communications with mobile stations located within femtocells

An apparatus in one example has: at least a first network of a first predetermined type and at least a second network of a predetermined type; at least one mobile terminal movable between the first and second networks; at least one gateway operatively coupled to each of the first and second networks; and at least one message that communicates via the gateway at least feature data of the mobile terminal from one of the first and second networks to the other of the first and second networks.

The present invention provides a method for establishing a multi-user call in a communication system. The communication system receives a call request to establish a group call with a shared group of users. The communication system determines which of the plurality of individual users should be excluded from the call and connects each of the group of included users to establish a multi-user call. The communication system preferably indicates that a unit was not currently available, for example by playing a prerecorded message, playing a tone and also preferably indicates why a unit was not available.

In a multimedia communications system (), a conference establishment server coordinates the scheduling of a conference call. The server receives request for conference calls (). The request includes a list of participants and may include an indication of the resources necessary and any rules for the conference call. The request may indicate critical resources or participants that are required for the call. Based on the request, the server determines a conference time and notifies participants of the time (). Prior to conference time, participants are reminded of the time and automatically connected to the call. The server may check the status of users on the telecommunications network to determine availability. If a critical participant or resource is unavailable at conference time, the conference may be cancelled with notification to the participants.

The present invention provides a method and communication system for sending a data message from a called phone to a calling phone while maintaining an active communication between the called phone and a first phone. The calling phone sends a call request to the called phone while the called phone is involved in an active communication with the first phone. The called phone sends a data message to the calling phone in response to the call request. The data message is sent while maintaining an active call with the first phone, so that the first phone is not placed 'on hold'.

Method and system for sending a data message to a calling phone while communicating with a first phone

The present invention provides a method and communication system for sending a data response from a called phone to a calling phone in response to a call request from the calling phone. The calling phone sends a call request to the called phone. The call request is a request to establish a communication between the called phone and the calling phone on a call path. If the called phone decides not to answer the call request, the called phone can send a data message to the calling phone. If the calling phone is data-capable, the data message is sent directly to the calling phone. If the calling phone is not data-capable, the data message is sent to a server that converts the data message to a voice message and sends the voice message to the calling phone. The calling phone can send a message back to the called phone in response to the data message sent from the called phone. If the calling phone is not data-capable, the response message is sent to a server that converts the voice message to a data message and sends the data message to the called phone. If the calling phone is data capable, the calling phone sends the response data message directly to the called phone.
