Method, system and apparatus for using IMS communication service identifier
View Patent ↗A method includes obtaining, by an HSS, information related to a user subscribed IMS communication service identifier, and sending information of a user subscribed IMS communication service identifier to a SID-requiring network entity according to the information related to the user subscribed IMS communication service identifier.
1. A method for using a communication service identifier (SID) in an IP Multimedia Subsystem (IMS) network, the method comprising:
obtaining, by a home location register (HSS), information related to a user subscribed SID; and
sending, by the HSS, the SID to a network entity according to the information related to the SID; wherein the SID is for identifying an IMS service, and the network entity performs operations according to the SID; and,
wherein the network entity includes an application server (AS);
the HSS determines arrival of the information related to the SID when the information related to the SID is updated; and
the HSS sends the updated information related to the SID to the AS, wherein the AS has a subscription relationship with a changed IMS communication service identifier.
2. A home location register (HSS), comprising a processor configured to perform the following method:
obtaining information related to a user subscribed communication service identifier (SID); and
sending the SID to a network entity in an IP Multimedia Subsystem (IMS) network according to the information related to the SID, wherein the SID is for identifying an IMS service, and the network entity performs operations according to the SID; and,
wherein the network entity includes an application server (AS);
the HSS determines arrival of the information related to the SID when the information of related to the SID is updated; and
the HSS sends the updated SID to the AS, wherein the AS has a subscription relationship with a changed IMS communication service identifier.
3. A network entity in an IP Multimedia Subsystem (IMS) network, the network entity comprising a processor configured to perform the following method:
receiving a user subscribed communication service identifier (SID) from a home location register (HSS) after the HSS has determined arrival of information related to the SID;
performing operations according to the SID wherein the SID is used to identify an IMS service; and,
wherein the network entity includes an application server (AS);
the HSS determines arrival of the information related to the SID when the information of related to the SID is updated; and
the HSS sends the updated SID to the AS, wherein the AS has a subscription relationship with a changed IMS communication service identifier.
