A method of performing operations for establishing a link to at least a homogeneous or heterogeneous network in a multi-mode mobile terminal, the method comprising: receiving (S6, S26) a first message from an upper layer module of the multi-mode mobile terminal to command establishment of a link to a first network at a media independent handover, MIH, module of the multi-mode mobile terminal, wherein the first message includes link type information and address information used for indicating the first network to which the link is to be established, the link type information indicates one of a plurality of link types including IEEE 802.11 and IEEE 802.16, and the MIH module is configured for converging information received from at least two network interface modules of the multi-mode mobile terminal associated with the at least one of a homogeneous or heterogeneous network into a unified presentation to be provided to the upper layer module; sending (S7, S27) a second message from the MIH module to a network interface module associated with the first network among the at least two network interface modules of the multi-mode mobile terminal based on the link type information and the address information in response to receipt (S6, S26) of the first message at the MIH module, wherein the second message is used to establish the link to the first network; performing an operation for establishing the link with an interface module of the first network in response to receipt (S7, S27) of the second message at the network interface module associated with the first network; transmitting (S10, S30) a first confirmation message from the network interface module associated with the first network to the MIH module as a result of performing the operation for establishing the link the first confirmation message indicating a result of the operation to the MIH module, wherein the result of the operation includes fail, and transmitting a second confirmation message from the MIH module to the upper layer module in response to receipt (S10, S30) of the first confirmation message at the MIH module, the second confirmation message indicating the upper layer module that the result of the operation is a fail, wherein the second confirmation message includes link type information and address information used for indicating a network related with the result of the operation. receiving (S6, S26) a first message from an upper layer module of the multi-mode mobile terminal to command establishment of a link to a first network at a media independent handover, MIH, module of the multi-mode mobile terminal, wherein the first message includes link type information and address information used for indicating the first network to which the link is to be established, the link type information indicates one of a plurality of link types including IEEE 802.11 and IEEE 802.16, and the MIH module is configured for converging information received from at least two network interface modules of the multi-mode mobile terminal associated with the at least one of a homogeneous or heterogeneous network into a unified presentation to be provided to the upper layer module; sending (S7, S27) a second message from the MIH module to a network interface module associated with the first network among the at least two network interface modules of the multi-mode mobile terminal based on the link type information and the address information in response to receipt (S6, S26) of the first message at the MIH module, wherein the second message is used to establish the link to the first network; performing an operation for establishing the link with an interface module of the first network in response to receipt (S7, S27) of the second message at the network interface module associated with the first network; transmitting (S10, S30) a first confirmation message from the network interface module associated with the first network to the MIH module as a result of performing the operation for establishing the link the first confirmation message indicating a result of the operation to the MIH module, wherein the result of the operation includes fail, and transmitting a second confirmation message from the MIH module to the upper layer module in response to receipt (S10, S30) of the first confirmation message at the MIH module, the second confirmation message indicating the upper layer module that the result of the operation is a fail, wherein the second confirmation message includes link type information and address information used for indicating a network related with the result of the operation.
