Problems solved by technology

If the UE performs unrestricted services on the source network, when the UE switches from 3GPP to a non-3GPP network, if the UE is in a restricted service mode on the non-3GPP network, no matter whether it is optimized or non-optimized handover, the non-3GPP network cannot judge the The APN and PGW (Packet Data Network Gateway) related to unrestricted services will release the unrestricted services currently being executed by the UE, so that they cannot provide services for unrestricted services and complete the switching of unrestricted services

Embodiment 1

[0040] image 3 It is a flowchart of an information processing method for unrestricted services in network switching provided by Embodiment 1 of the present invention, as shown in image 3 As shown, when the service of the user terminal on the target network is restricted and the service is not restricted on the source network, including:

[0041] Step 11, the network entity of the target side network obtains the APN information and the unrestricted service identifier of the user terminal's unrestricted service.

[0042] The unrestricted service identifier can take the following two forms: 1) The unrestricted service identifier can be separate indication information. In this manner, an unrestricted service indication identifier needs to be newly added for the APN and PGW information pair or the APN information. 2) It is also possible to set the unrestricted service identifier in the APN information in the form of an identifier bit, which requires setting a flag bit in the AP...

Embodiment 2

[0070] The information processing method for unrestricted services in network switching in this embodiment includes: the network entity of the source side network obtains the APN information and unrestricted service identifier of the unrestricted service of the user terminal, and sends the APN of the unrestricted service Information and unrestricted service identifiers, the APN information and unrestricted service identifiers of unrestricted services are used when the service of the user terminal on the target side network is restricted, the network entity of the target side network according to the unrestricted The APN information of the service and the unrestricted service identifier send first indication information to the PGW or SGW related to the unrestricted service, where the first indication information is used to indicate that the service of the user terminal on the target side network is limited, The PGW or SGW performs creation and / or data forwarding of bearers relat...

Embodiment 3

[0082] Figure 4 The signaling flow chart of the information processing method for unrestricted services in network switching provided by Embodiment 3 of the present invention. In this embodiment, the source-side network is a 3GPP network, the target-side network is a non-3GPP network, and the network switching type is optimization switch. Such as Figure 4 shown, including:

[0083] A. Attachment

[0084] In step 101, the UE attaches to the 3GPP network and establishes an APN bearer. The UE currently executes emergency services. The APN can support both non-emergency services and emergency services.

[0085] Step 102, when the UE performs the emergency service, the MME sends a NotifyRequest (NotifyRequest) message to the HSS, and registers the APN and PGW information, which may include APN and PGW information related to the emergency service with emergency service indication information, to the HSS, HSS can transmit these information to slave A. Here, the APN and PGW rel...

Abstract

The embodiment of the invention relates to a method and a device for processing information of an unrestricted service in network switch. The method comprises the following steps: acquiring APN information and an unrestricted service identifier of the unrestricted service of a user terminal; and transmitting first indicating information to PGW or SGW relevant to the unrestricted service, wherein the first indicating information is used for indicating that the service of the user terminal is restricted in a target side network, and PGW or SGW establishing loading and / or forwarding data relevant to the unrestricted service. By using the method and the device of the embodiment, the target side network acquires the APN information and the unrestricted service identifier of the unrestricted service to inform relevant PGW or SGW of service restriction of the user terminal so as to successfully complete the network switch of the unrestricted service and overcome the defect that all currently performed services of the user terminal are released because a network entity on a target side cannot acquire PGW or SGW of the unrestricted service.

Description

technical field [0001] Embodiments of the present invention relate to an information processing method and device, in particular, an information processing method and device for unrestricted services in network switching, and belong to the field of communication technologies. Background technique [0002] Since a 3GPP (Third Generation Partnership Project) network and a non-3GPP network exist simultaneously in the current wireless communication network architecture, a UE (user terminal) needs to switch between the 3GPP network and the non-3GPP network. The network where the UE is located before the network handover is called the source-side network, and the network where the UE is located after the handover is called the target-side network. [0003] For 3GPP networks and non-3GPP networks, according to whether services are restricted, services can be classified into restricted services (generally some routine services) and unrestricted services (such as emergency services, ...
