Abstract

The present invention manages media gateway control (megaco) protocols according to changes of lower layer network protocol by implementing the megaco package in the network adaptor. A method for managing the megaco protocols by using a network adaptor includes steps of: a) requesting an installation of a megaco protocol package to a network adaptor; b) determining whether the megaco protocol exists in a network protocol table; c) adding a new protocol in the network protocol table; d) searching a specific megaco protocol package in the megaco protocol package list by using the specific package ID and connecting the specific megaco protocol package; and e) installing the megaco protocol packages and the specific megaco protocols, and managing the megaco protocols.

Claims

1. A method for managing media gateway control (megaco) protocols by using a network adaptor, comprising the steps of:

a) requesting an installation of a megaco protocol package of low level network protocols to a network adaptor;

b) determining whether a megaco protocol exists in a network protocol table;

wherein the network protocol table includes company information as a data field in the network protocol table for requesting a specific megaco protocol in a case that a protocol standard is not defined;

c) adding a new protocol in the network protocol table in case that the megaco protocol does not exist in the network protocol table;

d) searching a specific megaco protocol package in a megaco protocol package list by using a specific package ID and connecting the specific megaco protocol package in case that the megaco protocol exists in the network protocol table, wherein said step d) includes the steps of;

d1) extracting the specific package ID from the network protocol table and searching the megaco protocol package in the megaco protocol package list by using the specific package ID,

d2) determining whether the searched megaco protocol package is the specific megaco protocol package, and

d3) proceeding the process to said step e) in case that the searched megaco protocol package is not the specific megaco protocol package and connecting the specific megaco protocol package in case that the searched megaco protocol package is the specific megaco protocol package; and

e) installing the megaco protocol package and the specific megaco protocol package and managing the megaco protocol.

2. The method as recited in claim 1, wherein the network protocol table includes protocol identification (ID), protocol version information, company information and the specific package ID.

3. The method as recited in claim 2, wherein the megaco protocol package list includes package ID, package version information, property information, event information, signal parameter, statistic information and specific protocol ID.

4. The method as recited in claim 1, wherein said step c) includes the steps of:

c1) requesting to add the new protocol in the network protocol table;

c2) determining whether the new protocol exists in the network protocol table;

c3) finishing the process in case that the new protocol does not exist in the network protocol table; and

c4) adding the new protocol in the network protocol table and storing a new specific package ID of the new protocol in the network protocol table in case that the new protocol exists in the network protocol table.

5. The method as recited in claim 4, wherein said step c4) includes the steps of:

c41) adding the new protocol package in the network protocol table;

c42) determining whether the new protocol needs a new megaco protocol package;

c43) storing the new protocol in the existing megaco protocol package in case that the new protocol does not need the new megaco protocol package; and

c44) generating the new megaco protocol package, allowing a new package ID of the new megaco protocol package and storing the new package ID in a field of the package ID.

6. The method as recited in claim 5, wherein said step c43) includes the steps of:

c431) generating the new megaco protocol package;

c432) allocating the new package ID of the new megaco protocol package;

c433) storing the new package ID in the field of the package ID of the megaco package list; and

c434) storing the new package ID in a field of the specific package ID of the network protocol table.

7. A computer readable recording medium for executing a method for managing megaco protocols by using a network adaptor, comprising the functions of:

a) requesting an installation of a megaco protocol package of low level network protocols to a network adaptor;

b) determining whether a megaco protocol exists in a network protocol table wherein the network protocol table includes company information as a data field in the network protocol table for requesting a specific megaco protocol in a case that a protocol standard is not defined;

c) adding a new protocol in the network protocol table in case that the megaco protocol does not exist in the network protocol table;

d) searching a specific megaco protocol package in a megaco protocol package list by using a specific package ID and connecting the specific megaco protocol package in case that the megaco protocol exists in the network protocol table, wherein said step d) includes the steps of;

d1) extracting the specific package ID from the network protocol table and searching the megaco protocol package in the megaco protocol package list by using the specific package ID,

d2) determining whether the searched megaco protocol package is the specific megaco protocol package, and

d3) proceeding the process to said step e) in case that the searched megaco protocol package is not the specific megaco protocol package and connecting the specific megaco protocol package in case that the searched megaco protocol package is the specific megaco protocol package; and

e) installing the megaco protocol package and the specific megaco protocol package and managing the megaco protocol.
