Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a mobility agent terminal, as shown in fig. 1, including the following steps:

step 101, receiving a first message sent by a network side device, where the first message is used to page a first terminal or notify the first terminal that there is downlink signaling or downlink data.

The mobile agent terminal refers to a terminal in a certain terminal group which can replace other terminals to process downlink messages of other terminals. After forming the terminal group, a certain terminal may be designated or elected as a mobility agent terminal.

In the embodiment of the invention, for accurately determining the paging object, the GUTI of the first terminal is included in the first message. Thus, the mobility agent terminal may determine the first terminal from the GUTI and send the second message to the first terminal over a direct link, including at least one of the following information in the second message: TGT, NAS Notification and the GUTI.

In this step, the mobility agent terminal receives a first message sent by the network side device when it is determined that the first terminal can be paged through the mobility agent terminal or the first terminal is notified of downlink signaling or downlink data. Specifically, when it is determined that the mobility agent terminal and the first terminal belong to the same terminal group, the network side device determines that the first terminal can be paged through the mobility agent terminal or notifies the first terminal of downlink signaling or downlink data.

And step 102, sending a second message to the first terminal according to the first message, wherein the second message is used for triggering the first terminal to establish connection with a network side.

On the basis of the above embodiment, the mobility agent terminal may further send a registration request to the network side device, where the registration request carries indication information, and the indication information is used to indicate that the mobility agent terminal is a mobility agent of an appointed terminal group. For example, the mobility agent terminal may indicate the designated terminal group to the network side device through the TGT. In this way, the mobility agent terminal notifies the network side device that the mobility agent terminal can be notified first when a certain terminal in the designated terminal group corresponding to the TGT needs to be paged, or when a certain terminal in the designated terminal group corresponding to the TGT has downlink signaling or downlink data.

In order to enable the terminals in the terminal group to definitely know the terminal group to which the terminals belong, the mobility agent terminal can also send the identifier of the mobility agent terminal to the first terminal through the direct link. Specifically, the mobility agent terminal receives the third message of the first terminal through the direct link. And under the condition that the identity of the first terminal is determined to be legal according to the third message, the mobile agent terminal sends the identifier of the mobile agent terminal to the first terminal through a direct link. For example, when a certain terminal needs to make the mobility agent terminal proxy signaling interaction with the network side device, the terminal may send a third message to the mobility agent terminal by using the PC5 interface, carrying the identifier of the terminal. The mobility agent terminal determines whether the terminal is legal by querying a V2X (vehicle to outside information exchange) application server.

In practical applications, a terminal within a group of terminals may wish to leave the group of terminals. At this time, the mobility agent terminal receives a fourth message sent by the first terminal through the direct link, wherein the fourth message is sent by the first terminal when the first terminal wants to leave the target terminal group. And the mobility agent terminal moves the first terminal out of the target terminal group according to the fourth message, and can send a fifth message to the network side equipment, wherein the fifth message is used for indicating the network side equipment to move the first terminal out of the target terminal group.

The target terminal group may be any terminal group to which the first terminal belongs, and the terminal group has the mobility agent terminal, and the mobility agent terminal is used to replace the first terminal to process the downlink message of the network side.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method according to an embodiment of the present invention, which is applied to a first terminal, and as shown in fig. 2, the method includes the following steps:

step 201, receiving a second message sent by a mobility agent terminal in a terminal group to which the first terminal belongs, where the second message is used to trigger the first terminal to establish a connection with a network side.

Wherein the mobility agent terminal and the first terminal communicate using D2D. The first terminal may be any terminal within a group of terminals.

In practical applications, the second message includes at least one of the following information: TGT, NAS notification, and GUTI.

And under the condition that the second message comprises a GUTI and an NAS notification, the first terminal initiates a service request process to a network side according to the NAS notification under the condition that the GUTI is matched with the GUTI of the first terminal.

If the second message further includes a TGT, the first terminal may also first determine whether it is located within a group of terminals to which the TGT corresponds. And if the first terminal is located in the terminal group corresponding to the TGT, initiating a service request process to a network side according to the NAS notification under the condition that the GUTI of the first terminal is matched with the GUTI of the first terminal.

Step 202, establishing a connection with the network side according to the second message.

On the basis of the above embodiment, before step 201, the method may further include: and acquiring the identifier of the mobile agent terminal sent by the mobile agent terminal. Specifically, the first terminal sends a third message to the mobility agent terminal through the direct link, and receives an identifier of the mobility agent terminal sent by the mobility agent terminal through the direct link, where the identifier of the mobility agent terminal is sent by the mobility agent terminal when the identity of the first terminal is determined to be legal according to the third message. Through the identifier of the mobile agent terminal sent by the mobile agent terminal, the first terminal can clarify the association relationship between the first terminal and the mobile agent terminal, and inform the network side equipment of the identifier of the mobile agent terminal, so that the network side equipment can clarify the association relationship between the first terminal and the mobile agent terminal.

After obtaining the identifier of the mobility agent terminal, the first terminal may further send a sixth message to the network side device, where the sixth message includes the identifier of the mobility agent terminal. Wherein the sixth message further comprises: a TGT of the first terminal. By the method, the network side equipment can accurately distinguish the terminal group to which the first terminal belongs.

When the first terminal needs to leave a certain terminal group, the first terminal can also inform the mobility agent terminal or directly inform the network side equipment.

Specifically, if the first terminal interacts with the network side device through the mobility agent terminal, the first terminal sends a fourth message to the mobility agent terminal through a direct link when the first terminal wants to leave the target terminal group, where the fourth message is used to instruct the mobility agent terminal to move the first terminal out of the target terminal group. And then, the mobile agent terminal informs the network side equipment to move the first terminal out of the target terminal group.

Or, since the first terminal is already located in a certain terminal group, the first terminal already determines the information of the mobility agent terminal and the network side device, and also already obtains the communication resource allocated to the first terminal by the network side device, so that the first terminal can directly interact with the network side device. Then, in a case that the first terminal wishes to leave the target terminal group, the first terminal sends a seventh message to the network side device, where the seventh message is used to instruct the network side device to move the first terminal out of the target terminal group. For example, after the connection between the first terminal and the mobility agent is interrupted for a period of time, the first terminal may send a seventh message to the network side device.

The target terminal group may be any terminal group to which the first terminal belongs. That is, the target terminal groups indicated by the fourth message and the seventh message may be the same terminal group or different terminal groups.

Referring to fig. 3, fig. 3 is a flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a network side device, as shown in fig. 3, including the following steps:

step 301, sending a first message to a mobility agent terminal in a terminal group to which a first terminal belongs, wherein the first message is used for paging the first terminal or notifying the first terminal that downlink signaling or downlink data exists.

Specifically, in this step, the network side device sends the first message to the mobility agent terminal in the terminal group to which the first terminal belongs, when determining that the first terminal can be paged through the mobility agent terminal or notifying that the first terminal has downlink signaling or downlink data. Specifically, when it is determined that the mobility agent terminal and the first terminal belong to the same terminal group, the network side device determines that the first terminal can be paged through the mobility agent terminal or notifies the first terminal of downlink signaling or downlink data. For example, the network side device may determine whether the mobility agent terminal and the first terminal belong to the same terminal group according to the TGT of the mobility agent terminal and the TGT of the first terminal.

Specifically, when sending the first message, the network side device may send the first message to the mobility agent terminal according to the identifier of the mobility agent terminal in the terminal context of the first terminal.

Step 302, establishing a connection with the first terminal.

On the basis of the above embodiment, the network side device may further receive a registration request sent by the mobility agent terminal, where the registration request carries indication information, and the indication information is used to indicate that the mobility agent terminal is a mobility agent of an appointed terminal group, and determine whether the mobility agent terminal can serve as a mobility agent of the appointed terminal group according to the indication information. For example, the mobility agent terminal authenticates the mobility agent terminal by querying the V2X application server. And if the authentication is passed, determining that the mobility agent terminal can be used as the mobility agent of the appointed terminal group. Wherein the designated terminal group is indicated by TGT.

In addition, in order to accurately determine a terminal that needs to send a message or page, the network side device may further receive a sixth message sent by the first terminal, where the sixth message includes an identifier of the mobility agent terminal, and the mobility agent terminal is used as a mobility agent of the first terminal.

Wherein the method may further comprise: allocating a special registration area and/or a special registration update period to the first terminal. The special registration area may be a whole PLMN (Public Land Mobile Network), and the special registration update period is a maximum duration supported by the communication system. By allocating a special registration area, the idle mobile registration updating process can be avoided; by allocating a special registration update period, periodic registration update procedures can be avoided.

When the first terminal needs to leave a certain terminal group, the network side device may further receive a fifth message sent by the mobility agent terminal, where the fifth message is used to instruct the network side device to move the first terminal out of a target terminal group, and update the terminal context associated with the identifier of the first terminal according to the fifth message. Or, the network side device may receive a seventh message sent by the first terminal, where the seventh message is used to instruct the network side device to move the first terminal out of the target terminal group.

In the embodiment of the present invention, specific implementation forms of the first message, the second message, the third message, the fourth message, the fifth message, the sixth message, and the seventh message are not limited, as long as both sides of the message can receive and analyze the message. In the embodiment of the present invention, the network side device may be, for example, an Access and Mobility Management Function (AMF).

Referring to fig. 4, fig. 4 is a schematic diagram of a connection relationship between devices in the embodiment of the present invention. The mobility agent terminal (Proxy UE) is connected with the network side through a Uu interface, and other terminals (D2D UE) in the terminal group communicate with the mobility agent terminal (Proxy UE) through a PC5 interface.

In the embodiment of the invention, for the scenarios such as car networking and unmanned cluster, after grouping the terminals, a mobility agent terminal (Proxy UE) is elected or designated to Proxy the mobility management signaling of other idle terminals (D2D UE). The mobility agent terminal and other terminals need to inform the network side of the agent relationship between them. Then, the network side will not require other terminals to perform the idle mobility management procedure. When the terminals have downlink signaling or data, the network side pages the terminals through the mobility agent terminal.

When the mobile agent terminal receives the paging notice about a certain terminal from the network side, the target terminal is searched through the terminal direct link. And after receiving the paging from the mobile agent terminal, the target terminal autonomously initiates an initial NAS signaling process to establish connection with the network.

Referring to fig. 5, fig. 5 is a schematic diagram of a process of signaling proxy activation in an embodiment of the present invention, including:

under the environment of the internet of vehicles, vehicle grouping and selection of a mobility agent terminal (or called leader UE) are completed through a V2X application layer, and TGT is generated.

The TGT may be recorded in the V2X application server or may be stored only in the terminal. The Leader UE is used to proxy members of the terminal group (called member UEs) to communicate with the network side.

Step 501, a Leader UE registers or re-registers to a core network, and carries a group Leader identity request (Leader request) in a Registration request (Registration request). Wherein, TGT may also be carried in the registration message.

Step 502, AMF completes Authentication/security check and Subscription check (Authentication/Subscription check) for leader UE. The AMF may need to further check whether the TGT provided by the leader UE is legitimate, for example by checking subscription information, or by querying the V2X application server.

Step 503, AMF confirms the identity of leader UE (leader _ reject _ check).

Step 504, AMF sends Registration accept message (Registration accept) to Leader UE, which may carry information (Leader Confirmed) confirming its group Leader identity, and UE ID (i.e. GUTI _0) of the Leader UE in 3GPP network.

Step 505, when the member UE needs to make the Leader UE Proxy signaling interaction between the Leader UE and the network side, the member UE sends a ProSe Proxy request (proximity Proxy request) to the Leader UE by using the PC5 interface, and carries the ProSe Proxy UE ID (proximity Proxy UE identity).

In step 506, the Leader UE confirms the legal identity of the member UE, for example, by querying V2X application server, and then notifies the member UE of the UE ID (3GPP Proxy UE ID, GUTI — 0) of the Leader UE in the 3GPP network through the proximity Proxy response.

Step 507, the member UE registers to the network, and sends a Registration request (Registration request) to the network side device, where the Registration request may carry an identifier (GUTI — 0) of the Leader UE. The Member UE may also carry the TGT.

Step 508, AMF completes Authentication/security check and Subscription check (Authentication/Subscription check) for the leader UE. The AMF records an ID (Identification) of the leader UE in the context of the member UE.

Step 509, AMF confirms the identity of the member UE (leader shift check). The AMF may check whether the TGT provided by the member UE matches the TGT provided by the leader UE, and if not, the leader UE is not used as a proxy.

For a member UE, the AMF allocates a very large registration area, e.g. the entire PLMN, for it. The AMF may also allocate a very large registration update period, for example, the period is an infinite length, or the period is a maximum duration supported by the communication system. In this way, idle state mobility registration update procedures and periodic registration update procedures may be avoided.

Step 510, the AMF sends a registration accept message to the member UE, and the registration message may carry the UE ID (GUTI _ x) of the member UE in the 3GPP network.

After receiving the registration acceptance message, the Member UE may no longer monitor the paging channel of the Uu interface.

Referring to fig. 6, fig. 6 is a schematic diagram of a process of deactivating a signaling proxy display in an embodiment of the present invention, where the process includes:

step 601, when the member UE wants to leave the current terminal group, it needs to send a message (ProSe de-Proxy request, proximity Proxy release request) to the leader UE, carrying the current ProSe UE ID (proximity UE identity) of the member UE and the UE ID (3GPP UE ID, that is, GUTIx) of the member UE in the 3GPP network.

In step 602, the Leader UE confirms the leaving of the member UE and transmits a Response (ProSe de-Proxy Response) to the member UE.

After receiving the response, the Member UE initiates a registration updating process and updates the position information of the Member UE to the AMF.

And 603, removing the member UE from the current terminal group by the Leader UE.

Step 604, the Leader UE sends Registration Request to AMF, which may carry Leader update indication and UE ID of the member UE in the 3GPP network (3GPP UE ID, GUTIx), so as to indicate to move the carried GUTIx out of the terminal group.

Step 605, AMF moves the member UE out of the terminal group.

Step 606, the AMF sends a Registration accept message (Registration accept) to the Leader UE.

AMF needs to update GUTIx associated UE context. Thereafter, AMF will start a mobile reachable timer for GUTIx to monitor if the member UE is offline.

The register update procedure can be initiated by the member UE, and the AMF waits for the register request of the member UE.

Referring to fig. 7, fig. 7 is a schematic diagram of a process of implicit deactivation of a signaling proxy in an embodiment of the present invention, where the process includes:

step 701, when the member UE detects that the D2D connection with the leader UE is disconnected for a period of time, it may autonomously decide to establish a connection with the network side. Wherein the time can be set as required.

In practical application, because the member UE can join a certain terminal group in the manner of the embodiment shown in fig. 5, and the connections with the mobility agent terminal and the network side device are made explicit and corresponding communication resources are obtained, when the member UE detects that the D2D connection with the leader UE is disconnected for a period of time, if the member UE autonomously decides that it needs to leave the terminal group that it has joined, the member UE can directly communicate with the network side device. At this time, the member UE sends Registration Request to AMF, which may carry leader update indication and guiti _0 of the leader UE, for indicating to move out of leader update of guiti _ 0. If the Leader update indication and the GUTI _0 are not carried, after the Member UE enters an idle state, AMF continuously maintains the Leader update of the GUTI _0, namely continuously maintains the relationship between the Leader UE corresponding to the GUTI _0 and the Member UE.

In step 702, if the AMF moves the UE out of the leadership of GUTI _0, the AMF should perform a normal registration update procedure, i.e. allocate a suitable TA (Tracking Area) list and a periodic update timer value.

Step 703, the AMF sends a Registration accept message (Registration accept) to the member UE.

Referring to fig. 8, fig. 8 is a schematic process diagram of a downlink paging procedure in the embodiment of the present invention, including:

step 801, when the member UE has downlink signaling (DL signaling), the AMF checks whether the member UE is in a connected state. If yes, processing according to the existing flow; if not, checking the membership (terminal group relation) information of the member UE. And the AMF determines the leader UE in the terminal group according to the leader UE ID recorded in the member UE context.

Step 802, the AMF further determines whether the leader UE is in an idle state, and if so, the AMF needs to page the leader UE (Paging).

Step 803, the AMF sends NAS notification (NAS notification) message to the leader UE, carrying the GUTI of the member UE, for example, GUTIx.

Step 804, after receiving the NAS notification, the Leader UE determines the designated cell UE which needs to be paged. The Leader UE performs group broadcast through the PC5 interface, and the TGT, NAS notification, and encrypted GUTIx are carried in a proximity Proxy broadcast message (ProSe Proxy Announce).

Step 805, after receiving the ProSe Proxy Announce, the Member UE checks whether the Member is a group Member of the TGT, and if yes, parses GUTIx.

If the member UE finds its GUTI matching the GUTIx in the broadcast message, it sends a proximity Proxy broadcast acknowledgement (ProSe Proxy Announce ACK) to the leader UE.

Step 806, the Member UE initiates a Service Request process to the AMF according to the NAS notification in the broadcast message, and establishes a connection with the core network.

As can be seen from the above description, in the embodiment of the present invention, the mobility agent terminal in the terminal group replaces and processes the downlink message of the idle terminal in the terminal group, so that the location update of the terminal in the terminal group can be avoided, the signaling overhead in the network can be reduced, and the air interface resources can be saved.
