Problems solved by technology

Since the UICC less UE does not have IMSI (international mobile subscriber identity, International Mobile Subscriber Identity) information, the MME cannot select an HSS for the UICC less UE, and cannot register the PDN GW information selected above into the HSS
Afterwards, the UICC less UE moves to the Non-3GPP network. Since the Non-3GPP network cannot obtain the PDN GW information selected for the PDN connection established for the emergency call of the UICC less UE in the 3GPP network, the Non-3GPP network cannot Restore the PDN connection established for the emergency call of UICC less UE in the 3GPP network, resulting in the interruption of the emergency call service
[0005] Similarly, when the UICC less UE is attached to the Non-3GPP network, since the Non-3GPP network cannot select an HSS for the UICCless UE, the PDN GW information selected for the emergency call cannot be registered in the HSS
Afterwards, the UICC less UE moves to the 3GPP network. Since the MME cannot obtain the PDN GW information selected for the PDN connection established for the emergency call of the UICC less UE in the Non-3GPP network, the MME cannot restore the Non-3GPP The PDN connection established for the emergency call of the UICCless UE in the network causes the emergency call service to be interrupted

Embodiment 1

[0037] Embodiment 1. A method for implementing an emergency service. This embodiment and the following embodiments are all described by taking the emergency service as an example of an emergency call service. The implementation process of other types of emergency services is similar to that of the emergency call service, and will not be described again. The flow of the implementation method of the emergency call service is as attached figure 1 shown.

[0038] Step 100, for the PDN connection successfully established for the emergency call of the UICC less UE, the mobility management entity sends information required for establishing the PDN connection to the storage network element. The mobility management entity is a network device responsible for obtaining information required to establish a PDN connection. For example, the mobility management entity is an MME in a 3GPP network; for another example, the mobility management entity is a mobile access gateway in a non-3GPP ne...

Embodiment 2

[0058]Embodiment 2: The UICC less UE accesses in 3GPP and initiates an emergency call service. The mobility management network element dynamically allocates an IMSI for the UICC less UE. The mobility management network element selects a home subscriber server according to the allocated IMSI, and sends The PDN GW information corresponding to the PDN connection established by the emergency call of the UICC less UE is registered in the selected home subscriber server. After that, the UICC less UE moves from the 3GPP network to the non-3GPP network; in the above cases, the emergency call service is implemented The process is attached Figure 2a And attached Figure 3a shown.

[0059] Figure 2a It shows the flow of the UICC less UE accessing and initiating an emergency call service in the 3GPP network, that is, the initial attachment flow of the UICC less UE in the 3GPP network.

[0060] Step 1. The UE sends an attach request message to the mobility management network element, ...

Embodiment 3

[0078] Embodiment 3: The UICC less UE accesses in non-3GPP and initiates an emergency call service. The mobile access gateway dynamically allocates an IMSI for the UICC less UE, and the mobile access gateway selects a home subscriber server according to the allocated IMSI, and sends the service to the UICC less UE. The PDN GW information corresponding to the PDN connection established by the emergency call of the less UE is registered in the selected home subscriber server. After that, the UICC less UE moves from the non-3GPP network to the 3GPP network; in the above cases, the emergency call service implementation process as attached Figure 4a And attached Figure 5a shown.

[0079] Figure 4a It shows the process of UICC less UE accessing in non-3GPP network and initiating an emergency call service, that is, the initial attach process of UICC less UE in non-3GPP network.

[0080] Step 1. The UE discovers and selects a mobile access gateway in a non-3GPP network.

Abstract

The embodiment discloses a method, a system and network equipment for realizing urgent services. The method comprises: receiving a switching request from terminal equipment UICC less UE without signing data; making sure that UICC less UE switches between a 3GPP (3rd Generation Partner Project) network and a non-3GPP (3rd Generation Partner Project) network in the process of performing urgent services; and resuming the Packet Data Network (PDN) connection of UICC less UE for urgent services according to the obtained information of the PDN connection of UICC less UE. The technical scheme can prevent interruptions when UICC less UE switches between the 3GPP (3rd Generation Partner Project) network and the non-3GPP (3rd Generation Partner Project) network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an emergency service realization method, an emergency service realization system and network equipment. Background technique [0002] When a UE (user equipment) attaches to a 3GPP network or a Non-3GPP (non-3GPP) network, it usually needs to obtain the subscription data of the UE from the HSS (Home Subscriber Service, Home Subscriber Service), such as the MME (Mobility Management Entity, mobility management entity) obtains the subscription data of the UE from the HSS. However, when the UICCless UE (the user equipment with the default subscription data) does not obtain the subscription data of the UE from the HSS when the 3GPP network is attached or the Non-3GPP network is attached, the UICC less UE can only perform emergency services, such as emergency call business. [0003] In the process of implementing the present invention, the inventors found that when the U...
