Abstract
A method and a proxy server for selecting an input server of an IMS communication network in order to register a terminal in the IMS communication network. Following receipt from the terminal of an SIP registration message, the proxy server obtains a value of at least one field of the SIP registration message, the field being representative of a characteristic belonging to the terminal, and selects an input server using the at least one value obtained. Then, the proxy server sends, to the terminal, an SIP redirection message including an IP address of the selected input server.

A method implemented by a proxy server of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, comprising:
- receiving from a terminal a first registration request sent according to a Session Initiation Protocol (SIP);
- obtaining a value of at least one field of the first registration request, said field being representative of a characteristic specific to the terminal;
- selecting, from at least said obtained value, an entry server of a set of entry servers of said IMS communication network, said selected entry server having a configuration suited to said characteristic;
- and
- sending to the terminal a SIP redirect message comprising an IP address of the selected entry server to be used for at least one subsequent registration request of the terminal for registering to the IMS network.
A method implemented by a terminal of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, comprising:
- sending a first registration request to a proxy server of the IMS communication network, said first registration request comprising at least one field representative of a characteristic specific to the terminal;
- receiving, from the proxy server, a redirect message comprising an IP address of an entry server of the IMS communication network, the entry server having been selected by the proxy server from a value of said at least one field and having a configuration suited to said characteristic;
- and
- sending at least one subsequent registration request for registering to the IMS network to the entry server of the IMS communication network.
A proxy server of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the proxy server to perform acts comprising:
- receiving from a terminal a first registration request sent according to a Session Initiation Protocol (SIP);
- obtaining a value of a field of the first registration request, said field being representative of a characteristic specific to the terminal;
- selecting, from the obtained value, an entry server having a configuration suited to said characteristic;
- and
- sending to the terminal a SIP redirect message comprising an IP address of the selected entry server to be used for at least one subsequent registration request of the terminal to the IMS network.
A terminal comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the terminal to perform acts comprising:
- sending a first registration request to a proxy server of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, said first registration request comprising at least one field representative of a characteristic specific to the terminal;
- receiving, from the proxy server, a redirect message comprising an IP address of an entry server of the IMS communication network, the entry server having been selected by the proxy server from a value of said at least one field and having a configuration suited to said characteristic;
- and
- sending at least one subsequent registration request for registering to the IMS network to the entry server of the IMS communication network.
A non-transitory computer-readable medium comprising program code instructions stored thereon for executing, when the instructions are run by a processor of a proxy server of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, a method comprising:
- receiving from a terminal a first registration request sent according to a Session Initiation Protocol (SIP);
- obtaining a value of at least one field of the first registration request, said field being representative of a characteristic specific to the terminal;
- selecting, from at least said obtained value, an entry server of a set of entry servers of said IMS communication network, said selected entry server having a configuration suited to said characteristic;
- and
- sending to the terminal a SIP redirect message comprising an IP address of said selected entry server to be used for at least one subsequent registration request of the terminal to the IMS network.
A non-transitory computer-readable medium comprising program code instructions for executing, when the instructions are run by a processor of a terminal of an Internet Protocol (IP) Multimedia Subsystem (IMS) communication network, a method comprising:
- sending a first registration request to a proxy server of the IMS communication network, said first registration-request comprising at least one field representative of a characteristic specific to the terminal,
- receiving, from the proxy server, a redirect message comprising an IP address of an entry server of the IMS communication network, the entry server having been selected by the proxy server from a value of said at least one field and having a configuration suited to said characteristic;
- and
- sending at least one subsequent registration request for registering to the IMS network to the entry server of the IMS communication network.
