Abstract
The present invention provides a method, a subscriber server and a mobility management entity for determining a serving node of a short message service. After receiving a location update request sent by an MME, an HSS/HLR determines services subscribed to by a subscriber. When determining that the subscriber has not subscribed to a CS domain service or there is only an SMS service in CS domain services subscribed to by the subscriber, the HSS/HLR registers the MME as a serving node that provides the SMS service for the subscriber.
Claims15
A method for determining a serving node of a short message service, the method comprising:
- receiving a location update request sent by a mobility management entity (MME), wherein the location update request carries a subscriber identity, and wherein the location update request does not carry indication information for registering the MME as a serving node that provides a short message service (SMS) service for a subscriber;
- determining, according to the location update request, the subscriber identity, and stored subscription information regarding the subscriber identity, whether the subscriber has subscribed to a circuit switched (CS) domain service or whether the SMS service is the only CS domain service subscribed to by the subscriber;
- and
- in response to determining that the subscriber has not subscribed to the CS domain service or the SMS service is the only CS domain service subscribed to by the subscriber, registering the MME as the serving node that provides the SMS service for the subscriber.

A method for determining a serving node of a short message service, the method comprising:
- receiving a combined evolved packet system (EPS) or international mobile subscriber identity (IMSI) attach request or a combined tracking area (TA) or location area (LA) update request sent by a user equipment, wherein the combined EPS/IMSI attach request or the combined TA/LA update request does not carry SMS only indication information;
- in response to determining that the combined EPS/IMSI attach request or the combined TA/LA update request does not carry SMS only indication information, sending a location update request to a home subscriber server or home location register HSS/HLR, wherein the location update request carries a subscriber identity and indication information used to instruct the HSS/HLR to register, when a subscriber has not subscribed to a CS domain service or there is only a short message service (SMS) service in CS domain services subscribed to by the subscriber, a mobility management entity MME as a serving node that provides the SMS service for the subscriber, so that the HSS/HLR registers, according to the subscriber identity and the indication information, the MME as the serving node that provides the SMS service for the subscriber;
- and
- receiving a location update request response returned by the HSS/HLR, wherein the location update request response carries a registration complete indication, wherein the registration complete indication is used to notify the MME that the HSS/HLR has registered the MME as the serving node that provides the SMS service for the subscriber.

A subscriber server, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- receiving a location update request sent by a mobility management entity (MME), wherein the location update request carries a subscriber identity, and wherein the location update request does not carry indication information for registering the MME as a serving node that provides a short message service (SMS) service for a subscriber;
- determining, according to the location update request, the subscriber identity, and stored subscription information regarding the subscriber identity, whether the subscriber has subscribed to a CS domain service or whether the SMS service is the only CS domain service subscribed to by the subscriber;
- and
- in response to determining that the subscriber has not subscribed to the CS domain service or the SMS service is the only CS domain service subscribed to by the subscriber, registering the MME as a serving node that provides the SMS service for the subscriber.
