Embodiment 1

[0066] This embodiment implements a PS SMS implementation method for local non-roaming scenarios, such as Figure 5 shown, including:

[0067] Step 101, UE initiates a combined Attach / location update (combined Attach / TAU) request, and includes an SMS-only indication in the request message;

[0068] The joint attachment refers to: EPS / IMSI attach, wherein the IMSI attach is for SMS-only; the location update refers to: TAU / LAU;

[0069] The combined attach / TAU is sent to the corresponding MME.

[0070] Step 102, the MME queries the HSS for the subscription information of the UE, and when the MME supports PS SMS, sends an indication of supporting PS SMS to the HSS;

[0071] Wherein, the indication of supporting PS SMS may be carried when querying subscription information, or may be sent separately.

[0072] The MME refers to the serving MME in the area where the UE is located. In this embodiment, the MME supports the PS SMS function;

[0073] The MME receives the UE's combine...

Embodiment 2

[0088] This embodiment implements a PSSMS processing method for the scenario of in-band roaming and the home network does not support PS SMS, such as Image 6 As shown, the method includes the following steps:

[0089] Step 201, the UE initiates a combined Attach / location update (combined Attach / TAU) request, and the SMS-only indication is included in the request message;

[0090] This step is the same as step 101 and will not be repeated here.

[0091] Step 202, the visited MME (visited MME) obtains the SMS subscription information on the HSS through the D interface;

[0092] Since the home network does not support PS SMS, the S6a interface does not provide SMS subscription information; the visited MME obtains the SMS subscription information on the HSS through the D interface; if the visited MME integrates the MSC function, the visited MME obtains it directly through the D interface SMS subscription information, otherwise the MSC obtains the SMS subscription information thro...

Embodiment 3

[0109] This embodiment implements a method for processing the effective time in the trigger information for the scenario where in-band roaming and the visited network does not support PS SMS, such as Figure 7 As shown, the method includes the following steps:

[0110] Step 301, UE initiates a combined Attach / location update (combined Attach / TAU) request, and includes an SMS-only indication in the request message;

[0111] This step is the same as step 101 and will not be repeated here.

[0112] Step 302, the visited MME obtains the SMS subscription information on the HSS through the D interface;

[0113] The visited MME does not support PS SMS, so the SMS subscription information cannot be obtained through the enhanced S6a interface, and the visited MME obtains the SMS subscription information through the D interface;

[0114] If the visited MME integrates the MSC function, the visited MME directly obtains the SMS subscription information through the D interface; otherwise,...

Abstract

A method for implementing a packet switch domain short message service (SMS) comprises: after receiving a request message sent by a user equipment and containing an SMS-only indication, a mobile management entity enquiring subscription information of the user equipment from a home subscriber server, and receiving the subscription information of the user equipment returned by the home subscriber server; and when the mobile management entity supports a packet switch domain short message service and the subscription information supports the packet switch domain short message service, the mobile management entity sending a request acceptance message to the user equipment, a short message service being received and sent between the mobile management entity and the user equipment through the packet switch domain. Embodiments of the present invention further provide a system for implementing a packet switch domain short message service, and a user equipment. By means of the solution of the present invention, the packet switch domain short message service can be implemented in an EPS system.

Description

technical field [0001] The present invention relates to the short message (SMS, Short Message Service) realization technology of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), relate in particular to a kind of packet domain (PS, Packet Switch domain) short message in Evolved Packet System (EPS, Implementation method, system and user equipment in Evolved Packet System). Background technique [0002] Mobile communication network services can be divided into two categories from the technical realization: one is circuit switching (CS, Circuit Switch) services, such as voice services and short message (SMS) services; the other is packet switching (PS, Packet Switch) services, such as web browsing business. [0003] In order to effectively utilize mobile network resources, 3GPP proposed Long Term Evolution (LTE, Long Term Evolution). LTE is a system architecture completely based on packets, and supports real-time services and voice conversation...
