Abstract
A SIP-based method for supplementary services configuration is extended by the introduction of means for a network to service supplementary services interrogation requests from a UE by responding to a SIP INVITE sent by the UE. The response may be a SIP message and include, e.g., in the SIP message body a machine-readable representation of the interrogated service's current configuration.
Claims15
1:
- A method, performed by a user equipment, UE, said UE being connected in a radio access network in a wireless communication system, the method comprising:
- transmitting, to a node in the wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE;
- and
- receiving, from the node in the wireless communication system, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
1 more element
2:
- The method of claim 1, wherein the reception of the SIP message comprises reception of any of a SIP BYE message and a SIP 200 OK message, and wherein the status of the supplementary service is comprised in the body of the received message.
3:
- The method of claim 1, wherein the status of the supplementary service associated with the UE is in any of a plain text format and an extensible markup language, XML, format.
4:
- The method of claim 1, wherein the transmission of the SIP INVITE message and the reception of the SIP message comprises transmission to and reception from an internet protocol multimedia subsystem, IMS, node, respectively.
5:
- The method of claim 1, wherein the supplementary service is any of:
- call forwarding,
- caller ID,
- call barring, and
- call waiting.
2 more elements
6:
- A method, performed by a node in a wireless communication system, the method comprising:
- receiving, from a user equipment, UE, being connected in a radio access network in the wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE;
- retrieving the status of a supplementary service associated with the UE;
- and
- transmitting, to the UE, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
2 more elements
7:
- The method of claim 6, wherein the transmission of the SIP message comprises transmission of any of a SIP BYE message and a SIP 200 OK message, and wherein the status of the supplementary service is comprised in the body of the transmitted message.
8:
- The method of claim 6, wherein the status of the supplementary service associated with the UE is in any of a plain text format and an extensible markup language, XML, format.
9:
- The method of claim 6, wherein the retrieving of the status of a supplementary service associated with the UE comprises receiving from a status database via a supplementary services settings server.
10:
- The method of claim 6, wherein the supplementary service is any of:
- call forwarding,
- caller ID,
- call barring, and
- call waiting.
2 more elements
11:
- A user equipment, UE, comprising radio frequency circuitry, and a memory, said memory containing instructions executable by said processor whereby said UE is operative to:
- transmit, to a node in a wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE;
- and
- receive, from the node in the wireless communication system, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
1 more element
12:
- A node, comprising input/output circuitry, a processor and a memory, said memory containing instructions executable by said processor whereby said node is operative, in a wireless communication system, to:
- receive, from a user equipment, UE, being connected via a radio access network to the wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE;
- retrieve the status of a supplementary service associated with the UE;
- and
- transmit, to the UE, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
2 more elements
13:
- A nontransitory computer readable storage medium comprising a computer program, comprising instructions which, when executed on at least one processor in a UE that is connected in a radio access network in a wireless communication system, cause the UE to carry out a method comprising:
- transmitting, to a node in the wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE, and
- receiving, from the node in the wireless communication system, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
14:
- A nontransitory computer readable storage medium comprising a computer program, comprising instructions which, when executed on at least one processor in a node in a wireless communication system, cause the node to carry out a method comprising:
- receiving, from a user equipment, UE, being connected in a radio access network in the wireless communication system, a session initiation protocol, SIP, INVITE message that comprises a man-machine interface, MMI, code that defines an interrogation regarding a status of a supplementary service associated with the UE,
- retrieving the status of a supplementary service associated with the UE, and
- transmitting, to the UE, a SIP message that comprises the status of the supplementary service associated with the UE, said status being in a machine readable format.
