Description

Delivery domain query method and device, and short message delivery method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for querying a delivery domain, a method and an apparatus for delivering a short message, a storage medium, and an electronic apparatus.
Background
The conventional Short Message Service processes a Message received from and sent to a user through a Short Message Service Center (SMSC) network element. When a Mobile Station (MS) sends a message to a receiver, the Mobile Station delivers the message to an SMSC through a Mobile Switching Center (MSC); after the SMSC requests routing information of the receiver MS from a Home Location Register (HLR) or a Home Subscriber Server (HSS), the message is delivered to the receiver through the MSC. When the message delivery fails, a message retry is performed at the SMSC. The SMSC carries a short message service through a mobile application Protocol (MAP for short).
In recent years, with the development of mobile networks, core networks have evolved into Long-Term Evolution (LTE) and fifth-Generation mobile communication technology (5G) networks, and network elements in IP Multimedia Subsystem (IMS) networks and 5G networks are communicated with each other through Session Initiation Protocol (SIP) and Hypertext Transfer Protocol (HTTP)/2, respectively, so that conventional short message services have changed.
In the IMS network, the third Generation Partnership Project (3rd 3GPP) specification introduces an Internet Protocol-Short Message-Gateway (IP-SM-GW) network element, which is linked with a Service-Call session control Function (S-CSCF) and an SMSC as a channel for Short Message interworking between the IMS network and the mobile network. When the UE registers in the IMS network, the IP-SM-GW registers its own address with the HSS/HLR. When UE submits IMS network message, IP-SM-GW forwards message to corresponding SMSC for subsequent flow process; when SMSC delivers message to UE, HSS/HLR directs message to IP-SM-GW for IMS network issue according to IP-SM-GW address registered by UE.
In the 5G network, the 3GPP specification introduces a Short Message Service Function (SMSF) network element, which is linked with an Access and Mobility management Function (AMF) and a Unified Data Manager (UDM) as a channel for Short Message interworking between the 5G network and other networks. In the message interworking principle, the same processing mechanism as the IP-SM-GW: when the UE is registered in the 5G network, the SMSF registers its own address with the UDM (role the same as HSS/HLR). When the UE submits the 5G network message, the SMSF forwards the message to a corresponding SMSC for subsequent flow processing; when SMSC delivers message to UE, UDM points message to SMSF for 5G network issue according to SMSF address registered by UE.
Before introducing the SMSF network element, when the receiver UE is registered in the IMS network, the SMSC will deliver the message to the IP-SM-GW after routing the request to the HSS/HLR, and if the IP-SM-GW fails to deliver the message to the receiver, the normal practice is to control the domain transfer by the IP-SM-GW to deliver to 2/3/4G network. In the scheme, the first delivery adopts a scheme with fixed IMS network priority; the failure domain selection adopts a method of global control domain transfer.
After introducing the SMSF network element, although only one delivery domain is added, the SMSF and the IP-SM-GW exist as two independent gateways, and no effective solution is provided in the prior art on how to carry out preferred delivery among the SMSC, the IP-SM-GW and the new network element SMSF and how to carry out handover domain delivery after failure.
In view of the above problems in the related art, no effective solution has been proposed.

That is, when the UE registers in the IMS network, the IP-SM-GW registers with the UDM/HSS/HLR, wherein the procedure of UE registration in the IMS network can be seen in fig. 3. When the UE registers in the 5G network, the SMSF registers with the UDM/HSS/HLR, wherein the flow of UE registration in the 5G network can be seen in fig. 4. After the UE registers in the network, the UE may send a short message through the corresponding network, where when the UE submits a message through the IMS network, the IP-SM-GW forwards the message to the SMSC after receiving the IMS network message, and the specific flow may refer to fig. 5 (in fig. 5 and other subsequent figures, MO represents Mobile Original, and MT represents Mobile Terminated); when the UE submits a message through the 5G network, the SMSF forwards the message to the SMSC after receiving the 5G network message, and the specific flow can be seen in fig. 6.
In an optional embodiment, the preset selection policy includes at least one of: when the query request is a first query request corresponding to the short message delivery from the requester and the UE is registered in both an Internet protocol multimedia subsystem (IMS) network and a fifth generation mobile communication technology 5G network or is registered only in the IMS network, the IMS network is preferably used as the delivery network of the short message; when the query request is a first query request corresponding to the short message delivery from the requester, and the UE is registered in both the IMS network and the 5G network or only the 5G network, preferably selecting the 5G network as the delivery network of the short message; when the query request is a second query request corresponding to the short message delivery from the requester and the UE is registered in both the IMS network and the 5G network, taking a network which is not selected as the delivery network of the short message in the IMS network and the 5G network as the delivery network of the short message; when the inquiry request is a second inquiry request corresponding to the short message delivery from the requester and the UE is registered in only one of the IMS network and the 5G network, taking one of a second generation mobile communication technology 2G network, a third generation mobile communication technology 3G network and a fourth generation mobile communication technology 4G network as a delivery network of the short message; and when the query request is a third query request corresponding to the short message delivery from the requester, taking one of a 2G network, a 3G network and a 4G network as a delivery network of the short message.

The routing information may include address information of the delivery domain. In the embodiment, the delivery domain is selected by using the management network element instead of selecting the delivery domain on the gateway, so that a fixed delivery domain selection principle does not need to be agreed uniformly for gateways of different networks, the flexibility of delivery domain selection is further improved, and the selection of the delivery domain is effectively realized.

step 1: when the SMSC needs to deliver the message to the UE, the SMSC inquires a delivery route to the UDM/HSS/HLR. And the UDM/HSS/HLR performs delivery domain selection (the domain selection is called as first delivery domain selection and corresponds to the delivery domain query flow corresponding to the first query request) according to a domain selection strategy (corresponding to the preset selection strategy), and returns SMSF or IP-SM-GW or 2/3/4G network routing information to the SMSC. SMSC selects SMSF or IP-SM-GW or 2/3/4G network delivery message according to the first delivery domain, and the specific flow is shown in step 2.
Step 2: the SMSC delivers the short message (which is called as a message for short in the following) according to the first delivery domain selection, which comprises the following conditions:
case 1) when the SMSC first domain selects to deliver the message to the UE through the SMSF, the SMSF receives the message from the SMSC and delivers the message to the 5G network. If delivery fails, the SMSF queries the UDM/HSS/HLR for a delivery route. And the UDM/HSS/HLR performs delivery domain selection (the domain selection is called as first failure delivery domain selection and corresponds to the delivery domain query flow corresponding to the second query request), and returns IP-SM-GW or 2/3/4G network routing information to the SMSF. The SMSF gates IP-SM-GW or 2/3/4G network delivery information according to the first failure delivery domain, and the specific flow is shown in step 3.
Case 2) when the SMSC first delivery domain is selected to deliver the message to the UE through the IP-SM-GW, the IP-SM-GW receives the message from the SMSC and delivers the message to the IMS network. If delivery fails, IP-SM-GW inquires delivery route to UDM/HSS/HLR. And the UDM/HSS/HLR performs delivery domain selection (the domain selection is called as first failure delivery domain selection and corresponds to the delivery domain query flow corresponding to the second query request), and returns SMSF or 2/3/4G network routing information to the IP-SM-GW. And the IP-SM-GW gates the SMSF or 2/3/4G network delivery message according to the first failure delivery domain, and the specific flow is shown in step 4.

case 1) when the SMSF first failure domain is selected to deliver the message to the UE through the IP-SM-GW, the IP-SM-GW receives the message from the SMSF and delivers to the IMS network. If delivery fails, IP-SM-GW inquires delivery route to UDM/HSS/HLR. And the UDM/HSS/HLR performs delivery domain selection (the domain selection is called secondary failure delivery domain selection and corresponds to the delivery domain query flow corresponding to the third query request), and returns 2/3/4G network routing information to the IP-SM-GW. And the IP-SM-GW delivers the message through the 2/3/4G network according to the secondary failure delivery domain selection.

And the UDM/HSS/HLR selects a delivery domain and returns 2/3/4G network routing information.
SMSF delivers the message to 2/3/4G network for the first time in the failed handover domain.
Strategy 2) when the IMS network is optimized by the first delivery domain selection, the domain selection is the second failure domain selection: returning 2/3/4G network routing information, which corresponds to a case that when the UE registers in the 5G and IMS dual networks, and prefers the IMS network, the UE delivers the first failure to 5G network delivery and the second failure to domain delivery to the IMS network, and the specific flow can refer to fig. 17, as shown in fig. 17, including the following steps:

strategy 1) when IMS network is preferred for first delivery domain selection, the domain selection here is first failure domain selection: if the registration information of the 5G network of the UE exists, selecting the SMSF as a delivery domain, and returning the SMSF routing information (this case corresponds to a case that when the UE is registered in a dual network of the 5G network and the IMS network, and when the IMS network is preferred, the delivery to the IMS network fails for the first time, and then the delivery to the 5G network is turned to, which may be specifically shown in fig. 14). If the registration information of the 5G network of the UE does not exist, 2/3/4G network routing information is returned, which corresponds to the case that the UE is registered in the IMS network and when the UE is not registered in the 5G network, the UE delivers the first-failure domain-transfer delivery to the IMS network, and the specific flow may refer to fig. 15, as shown in fig. 15, the following flow is included:

s1902, SMSC inquires routing information to UDM/HSS/HLR when delivering message to UE.
And the UDM/HSS/HLR selects a delivery domain and returns an SMSF/IP-SM-GW or 2/3/4G network delivery message.
Here, the domain selection policy of UDM/HSS/HLR is the same as the domain selection policy in the case where SMSF is deployed separately from IP-SM-GW. When UDM/HSS/HLR returns route information of SMSF or IP-SM-GW, SMSC delivers the message to the combined SMSF/IP-SM-GW.
SMSC delivers message to the combined SMSF/IP-SM-GW.
The combined SMSF/IP-SM-GW receives the message from the SMSC, and under the condition of preferably 5G network delivery, the message delivery is carried out according to the following flow:
step S1904, determine whether there is 5G network registration information, if yes, go to step S1906, otherwise, go to step 1908.
Step 1906, if there is 5G registration information, deliver the message to the 5G network, if delivery fails, go to step 1908.
Step S1908, if there is no 5G registration information, or after the message delivery to the 5G network fails, determine whether there is IMS network registration information, if so, go to step S1910, otherwise, go to step S1912.
Step S1910, when the IMS registration information exists, delivers a message to the IMS network.
Step S1912, if there is no IMS network registration information, or if the message delivery to IMS network fails, the combined SMSF/IP-SM-GW inquires routing information to UDM/HSS/HLR.
Step S1914, the UDM/HSS/HLR selects the delivery domain to return 2/3/4G network route information, and combines the SMSF/IP-SM-GW switching domain to deliver the message to 2/3/4G network.
If the message delivery to the 5G network fails, when the IMS registration information does not exist, the routing information is inquired from the UDM/HSS/HLR, and the UDM/HSS/HLR selects a delivery domain and returns 2/3/4G network routing information. And the combined SMSF/IP-SM-GW switching domain delivers a message to the 2/3/4G network.
In addition, when the UE is registered in the 5G network and the IMS network at the same time, and the SMSF registered by the UE is not in the same combined SMSF/IP-SM-GW with the IP-SM-GW, if the delivery of the message to the 5G network fails, when the collocated SMSF/IP-SM-GW does not have IMS network registration information, when the collocated SMSF/IP-SM-GW queries the UDM/HSS/HLR for routing information, the UDM/HSS/HLR returns routing information of another IP-SM-GW or another collocated SMSF/IP-SM-GW, and the SMSF/IP-SM-GW delivers the message to another IP-SM-GW or another collocated SMSF/IP-SM-GW, the further IP-SM-GW or the further co-located SMSF/IP-SM-GW delivers a message to the IMS network.
Here, jointly setting the SMSF/IP-SM-GW to inquire the routing information carrying address strategy to the UDM/HSS/HLR: if the message delivery to the 5G network fails, when the IMS network registration information does not exist, the SMSF address is carried when the route is inquired to the UDM/HSS/HLR. If the message delivery to the IMS network fails, the UDM/HSS/HLR is inquired about the route, and the route carries the IP-SM-GW address.
