Problems solved by technology

However, in some networks, due to various reasons, UE cannot perform emergency services in this part of the network
If the UE is switching from the source network to the target network while the UE is performing emergency services, and the target network does not support the current emergency services of the UE, the ongoing emergency services of the UE will be interrupted

Embodiment 1

[0043] refer to figure 1 , Embodiment 1 of the present invention provides an emergency business processing method, the method comprising:

[0044] 101. Acquire emergency service information of a network to be handed over by a user equipment UE that needs to be handed over and the emergency service information of the UE.

[0045] 102. According to the emergency service information of the network to which the UE is to be handed over and the emergency service information of the UE, determine whether there is a target network that supports the UE to perform emergency services in the network to which the UE is to be handed over, and if so, transfer the The emergency service performed by the UE is handed over to one of the target networks.

[0046] Wherein, the emergency service information of the network to be handed over by the UE includes an indication of a cause of service restriction supported by the network to be handed over by the UE, and the emergency service information of...

Embodiment 2

[0050] refer to figure 2 Embodiment 2 of the present invention provides a method for processing an emergency service, which is applicable when a UE in a restricted state and performing an emergency service undergoes a network handover, and the method includes:

[0051] 201. An access network element in a source network acquires a service restriction indication and a service restriction cause indication of a UE.

[0052]Due to the particularity of emergency services, the network may support emergency services performed by the UE under certain special circumstances, such as the UE does not have an International Mobile Subscriber Identification Number (IMSI), or the UE is in a restricted area, or the UE does not receive Network authorization, etc., if the UE does not have an IMSI, the reason for the service restriction at this time is that there is no IMSI; if the UE is in a restricted area, the reason for the service restriction is that the UE is in a restricted area; The reas...

Embodiment 3

[0086] refer to Figure 4 Embodiment 3 of the present invention provides a method for processing an emergency service, which is applicable when a UE in a normal state and undergoing an emergency service undergoes a network handover, and the method includes:

[0087] 401. An access network element in a source network acquires emergency service information of multiple networks, and the acquired emergency service information supported by each network includes: an indication of whether the network supports emergency services.

[0088] In this step, the manner in which the access network element in the source network obtains the emergency service information of multiple networks is similar to the five implementation manners in step 201 of Embodiment 2, which will not be repeated here.

[0089] 402. When it is learned that the UE needs to perform network switching, the access network element in the source network determines that the UE is performing emergency services according to t...

Abstract

The embodiment of the invention provides an emergency service processing method, emergency service processing equipment and a network system. The emergency service processing method comprises the following steps of: acquiring emergency service information of a network which is to be switched by user equipment UE needing switching and emergency service information of the UE; determining whether target networks which support the UE to perform emergency service are present in the network to be switched by the UE according to the emergency service information of the network to be switched by the UE and the emergency service information of the UE; if so, switching the emergency service performed by the UE to one of the target networks. The technical scheme provided by the embodiment of the invention can guarantee the uninterrupted emergency service when the UE performs network switching.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a processing method, equipment and network system for emergency services. Background technique [0002] At present, most networks support user equipment (User Equipment, UE) to perform emergency services. Whether it is a UE in a restricted state or a UE in an unrestricted state, most networks can use IP connectivity to access the network and IMS ( IP Multimedia Subsystem, IP Multimedia Subsystem) provides emergency services for the UE to ensure normal operation of the emergency services. However, in some networks, due to various reasons, the UE cannot perform emergency services in this part of the network. If the UE is switching from the source network to the target network while the UE is performing emergency services, but the target network does not support the current emergency services performed by the UE, the ongoing emergency services of the UE will be interrupted. ...
