Embodiment Construction

[0044] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0045] In this embodiment, a method for restoring a D2D service is provided, Figure 4 is a flowchart of a method for restoring a D2D service according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0046] Step S402, after the HSS is restarted, the user's location data update request message sent by the first MME is received;

[0047] In step S404, the HSS sends an insert user location data message to a short-range communication server (prose function), and the insert user location data message carries user location data related to short-distance communication services.

[0048] In this embodiment, through the above steps, after th...

Abstract

A method, device and Home Subscriber Server (HSS) for device to device service recovery are disclosed in the present invention. The method comprises that: after reboot, the HSS receives a user location data update request message transmitted by a first MME; and the HSS transmits an insert user location data message to a near field communication server, and the insert user location data message carries user location data related to a near field communication service. The present invention solves the problem in the related art of a communication policy of the near field communication server being caused to be inaccurate after the reboot of the HSS, and the accuracy and real-time capability of the communication policy of the near field communication server are improved, and a large amount of signaling resources do not need to be occupied and an HSS overload situation is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for resuming a device-to-device (Device to Device, D2D for short) service, and a Home Subscriber Server (Home Subscriber Server, HSS for short). Background technique [0002] Terminals in the adjacent area can use Device to Device (D2D for short) direct communication to bring many benefits to the terminal, such as higher speed, lower delay and lower power consumption, and also greatly improve the The operator's wireless resource efficiency and the D2D Relay mode are conducive to the operator's improvement of wireless coverage; for applications, using the proximity information in the D2D communication process can develop more attractive new services. A public safety (Public Safety) system can also use the D2D technology to realize communication between terminals without wireless coverage. [0003] figure 1 It is based on the schematic diagram of the D2D arc...
