Embodiment 1

[0526] see image 3 As shown, a specific description will be given for the first possible way.

[0527] The data network indicated by a certain DNN is LADN, and when the DNN is configured to the UE, indication information indicating that the data network corresponding to the DNN is LADN is also configured to the UE.

[0528] It should be noted that, the data network indicated by a certain DNN is LADN, technically it can be understood that the data network identified by the DNN is LADN, or it can be understood that the DNN is a DNN corresponding to LADN. . In the present invention, no specific technical distinction is made between the two description methods.

[0529] Configuration methods can include:

[0530] 1) Pre-configured in the UE, for example, when the UE subscribes to the LADN, configure the DNN and indication information in the universal subscriber identity module (universal subscriber identity module, USIM) or universal integrated circuit card (universalintegrate...

Embodiment 2

[0593] see Image 6 As shown, a specific description will be given for the second possible way.

[0594] The second possible way is: configure the DNNs corresponding to all the LADNs subscribed by the UE to the UE.

[0595] The configuration method is the same as that in Embodiment 1, and may include:

[0596] 1) Pre-configured in the UE. For example, when the UE subscribes to one or more LADNs, the DNNs of the one or more LADNs are configured in a universal subscriber identity module (universal subscriber identity module, USIM) or a universal integrated circuit card (universal integrated circuit card, UICC).

[0597] 2) Configured to the UE by the configuration device, for example, configured to the UE by UDM or PCF. For example, it is configured to the UE through OTA technology, OMA-DM and other methods.

[0598] 3) During the process of registering with the UE to the network side, the first core network device configures the UE. For example, core network equipment such...

Embodiment 3

[0632] see Figure 8 As shown, a specific description will be given for the third possible way.

[0633] A third possible way is: to propose a new way of configuring LADN information. For the convenience of description, the LADN information configured in this way is called the second LADN information.

[0634] Wherein, the second LADN information includes the DNN set of the LADN subscribed by the UE, and the service area information corresponding to the DNN of the LADN that the UE can use in the current registration area in the DNN set; the UE can use the DNN in the current registration area The LADN is located within the registration area of ​​the UE. The second LADN information does not include the service area information corresponding to the DNN of the LADN that the UE cannot use in the DNN set.

[0635] For example: the DNNs of the LADN subscribed by the UE include DNN1, DNN2 and DNN3. The LADN network names that the UE can use in the current registration area include ...

Abstract

An indication method and apparatus for a local area data network (LADN), for use in solving the problem of the prior art in a waste of signaling resource. The method comprises: obtaining first information, the first information comprising a first data network name (DNN) and a first indication for indicating that the first DNN is a DNN corresponding to an LADN, or the first information comprising a first DNN, the first DNN comprising a second indication for indicating that the first DNN is a DNN corresponding to an LADN; and determining that the first DNN is a DNN corresponding to an LADN according to the obtained first information so as to determine whether to send a PDU session establishment / modification / activation request message to a first core network device, the DNN corresponding to a PDU session being the first DNN. LADN information comprises the DNN of the LADN available for a terminal in the current registration area and service area information corresponding to the LADN.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method and device for indicating a local data network. Background technique [0002] The concept of a local area data network (LADN) is introduced in the fifth-generation mobile communication technology (the 5th-generation, 5G). A user equipment (user equipment, UE) can access the local data network only in a specific area, which is a service area (service area, SA) of the LADN. In addition, in 5G, the establishment of the protocol data unit (PDU) session is based on the application. Therefore, for the application applicable to LADN, the UE can only establish and use the PDU session whose data network is LADN when it is located in the LADN SA. . [0003] Since there is currently no effective way to determine whether the data network matched by the application is a local data network, when triggering certain applications applicable to LADN, whether the UE c...
