Description

FIELD OF TECHNIQUE

[001] Embodiments of the present invention relate to the field of wireless communications technologies and, in particular, to a method for reporting location information of user equipment and a device.

BACKGROUND

[002] With the development of a long-term evolution (LTE) system, a multi-stream aggregation (MSA) solution is introduced. In the MSA solution, multiple evolved nodeBs (eNB) can simultaneously provide services to a user equipment (UE), one eNB is a master evolved nodeB (MeNB) and other eNBs are secondary evolved nodeBs (Secondary Evolved B Node, SeNB).

[003] In the MSA solution, the UE establishes a control plane connection with only the MeNB serving the UE. Likewise, only the MeNB establishes a control plane connection with core network nodes such as a mobility management entity (MME), a server port (S-GW), and a packet data network port ( P-GW).

[004] Each core network node such as a load rules and policy control (PCRF) function in a network executes a corresponding control policy for the UE according to the location information of the UE, and the location information of the UE. UEs are obtained based on information about a serving cell in which the UE is located, and are reported to the core network node by an eNB of the serving cell via signaling. In the MSA solution, since only the MeNB establishes the control plane connection with the core network node, the core network node only receives serving cell information from the MeNB which is reported by the MeNB. Therefore, the UE location information is obtained based on the MeNB serving cell information.

[005] In a current method for reporting UE location information, a core network node can only receive serving cell information from a MeNB. Therefore, a granularity of location information obtained from the UE is not fine enough, and a granularity for the controlling UE is also not fine enough.

DESCRIPTION OF MODALITIES

[055] To make the objectives, the prior art solutions and the advantages of the embodiments of the present invention more clear, the following clearly describes the prior art solutions in the embodiments of the present invention with reference to the attached drawings in the embodiments of the present invention. Apparently, the embodiments described are some, but not all embodiments of the present invention. All other embodiments obtained by individuals of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[056] An MSA solution can include both a packet-based architecture and a radio access bearer-based architecture (RAB-based), the packet-based architecture is a 3C architecture for short, and the in RAB it is a 1A architecture for short.

[057] In the 3C architecture, the UE establishes a control plane connection only with a MeNB serving the UE, only a MeNB establishes a control plane connection with a core network node, and only the MeNB establishes a connection of user plane data with core network node. There is no connection between each SeNB serving the UE and the core network node, and the SeNB exchanges data with the MeNB. That is, in the 3C architecture, only the MeNB performs signaling and data exchange with the core network node, and both the data sent by the SeNB to a core network and the data sent from the core network to the SeNB need to be forwarded by the MeNB .

[058] In architecture 1A, the UE establishes a control plane connection with only one MeNB serving the UE, only one MeNB establishes a control plane connection with a core network node, and there is a data plane connection between the core network node and each of the MeNB and SeNB. However, a service is broadcast on only one MeNB or SeNB.

[059] A system architecture evolution system is used as an example. In the 3C architecture, signaling exchange is performed only between a MeNB and an MME, and data exchange is performed only between a MeNB and an S-GW. In the 1A architecture, the signaling exchange is performed only between a MeNB and an MME, but the data exchange is performed between an S-GW and each of a MeNB and a SeNB.

[060] UE location information in a network is obtained based on serving cell information from an eNB serving the UE, and the UE location information can be transmitted to a core network node in an attachment procedure , a Tracking Area Update (TAU), a Routing Area Update (RAU) procedure, or a service request procedure. In the MSA solution, only the MeNB establishes the control plane connection with the core network node in both the 3C architecture and the 1A architecture, and the UE location information is transmitted to the core network node via signaling in each procedure. . Therefore, the core network node can only receive MeNB serving cell information that is sent by the MeNB. That is, in the MSA solution, the UE location information is obtained based on the serving cell information of the MeNB serving the UE.

[061] However, in the MSA solution, a MeNB and one or more SeNBs simultaneously provide services to the UE. Therefore, the fact that only MeNB serving cell information is reported to the core network node makes the UE location information not accurate enough. An operator providing a network service can perform control such as load control, rate control and priority control on the UE according to the location information of the UE. Therefore, if the location information of the UE is not accurate enough, control with a finer granularity cannot be performed on the UE.

[062] It should be noted that a method for reporting location information of user equipment, and an apparatus that are provided in the present invention are applicable not only to the SAE system, but also to another network communications system such as a System Universal Mobile Telecommunications System (UMTS). One difference is that different communication systems have different network architectures, but in the communication systems, the method provided in the embodiments of the present invention can be used to report the location information of user equipment. In the following embodiments of the present invention, the SAE system architecture is used as an example to describe the method for reporting location information of user equipment provided in the present invention.

[063] Furthermore, in the embodiments of the present invention, the MeNB and the SeNB can separately be an access node in any form. For example, the MeNB and the SeNB are respectively a macro eNB and a peak eNB in the same system, or both the MeNB and the SeNB are a macro eNB in the same system, or the MeNB and the SeNB are access point (AP ) on an eNB and a wireless local area network (WLAN) respectively. MeNB and SeNB only need to simultaneously provide services to the UE.

[064] Figure 1 is a schematic structural diagram of embodiment 1 of a master access node according to an embodiment of the present invention. As shown in Figure 1, the master access node in this embodiment includes: a get module 11 and a send module 12.

[065] The obtaining module 11 is configured to obtain user equipment location information, wherein the user equipment location information includes serving cell information of at least one secondary access node of the user equipment.

[066] Specifically, the MeNB provided in this embodiment is configured to report the UE location information to a core network node, the MeNB provides a service to the UE, and the at least one SeNB also provides a service to the UE.

[067] The UE location information reflects a UE location and, in general, a coverage area of a serving cell of a MeNB is greater than a coverage area of a serving cell of a SeNB. Therefore, if the core network node obtains serving cell information from a SeNB serving the UE, a more accurate location of the UE is obtained. Thus, compared to a case where only serving cell information of the MeNB is reported to the core network node, when the serving cell information of the SeNB serving the UE is also reported to the core network node, the core network node core gets UE location information with a finer granularity.

[068] Therefore, the MeNB provided in this embodiment includes the obtaining module 11, and the obtaining module 11 is configured to obtain the UE location information, wherein the UE location information includes the serving cell information of the at least least one SeNB from the UE. The SeNB serving cell information can be any information that can represent a SeNB resource. The get module 11 can get the serving cell information from the SeNB through data exchange between the MeNB and the SeNB, or the get module 11 can get the serving cell information from the SeNB using information reported by the UE to the SeNB. MeNB.

[069] The sending module 12 is configured to send the location information of the user equipment to a core network node, where the location information is used by the core network node to determine a control policy for the equipment.

[070] Specifically, after the getting module 11 obtains location information from the UE, the sending module 12 sends the location information to the core network node. An SAE system is used as an example. The core network node includes an MME, an S-GW, a P-GW, a PCRF, and the like, the MME establishes a control plane connection with the MeNB, and the S-GW establishes a data plane connection. of user with the MeNB. The dispatcher module 12 can send the UE location information to the MME or the S-GW, the MME or the S-GW sends the UE location information to the PCRF using the P-GW, and the PCRF configures policies control or loading policies for the UE according to different UE location information, and sends the configured control or loading policies to an enforcement entity such as a load and policy enforcement function (PCEF) entity or a function reporting and bearer bonding (BBERF), in order to perform corresponding control in the UE.

[071] Since the UE location information includes the serving cell information of the at least one SeNB of the UE, the core network node can obtain a more accurate location of the UE according to the location information, so as to formulate a control policy with a finer granularity for the UE. Since there is the control plane connection and the user plane data connection between the MeNB and the core network node, the forwarding module 12 can send the UE location information to the core network node via signaling. control plane packet, or the forwarding module 12 can send the UE location information to the core network node using a user plane packet.

[072] In this modality, a MeNB obtains serving cell information from at least one UE SeNB, and sends the information to a core network node, so that the core network node can implement control with a finer granularity over the HUH.

[073] For two architectures in an MSA solution, the master access node shown in Figure 1 performs different specific processing methods, which are described in detail below.

[074] In an 1A architecture, the MeNB and the SeNB separately establish a user plane data connection with the core network node, that is, the MeNB and the SeNB separately establish a bearer with the core network node. Therefore, when the SeNB needs to provide a service to the UE, the sending module 12 in the MeNB can send a radio access bearer modification instruction message to the core network node, and the radio access bearer modification instruction message radio access includes the location information of the UE. In this way, the UE location information can be sent to the core network node without a need to change an existing signaling procedure. In that case, the serving cell information of the at least one SeNB of the UE includes: any one or more of identifying information of a serving cell of the at least one SeNB of the UE, bearer information that corresponds to a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE.

[075] The SAE system is used as an example to describe the previous MeNB processing. Figure 2 is a flowchart of signaling reporting location information using a bearer modification procedure in an SAE system. As shown in Figure 2, an MME, an S-GW, a P-GW, and a PCRF in the SAE system are collectively called a core network node.

[076] When a SeNB in a network starts serving the UE, a MeNB needs to notify the SeNB of related information such as network configuration, and in step S201, the MeNB can obtain serving cell information from the SeNB. The SeNB serving cell information can be any information that can represent a SeNB serving cell that serves the UE, for example, any one or more of SeNB serving cell identification information, bearer information that corresponds to the SeNB serving cell, a SeNB serving cell's tracking area identity, or a SeNB serving cell's access network type.

[077] The SeNB is newly added to serve the UE, the UE bearer information changes, the SeNB needs to establish a bearer with every node in a core network, and there is no control plane connection between the SeNB and the MME . Therefore, in step S202, the MeNB needs to send an Evolved Packet System Modification RAB (E-RAB) instruction message to the MME to instruct the MME to modify the bearer information of the UE. The E-RAB modification instruction message carries UE location information. In this embodiment, only one MeNB and only one SeNB serves the UE, and MeNB serving cell information can be sent to the MME when the MeNB establishes a bearer with each node in the core network. Therefore, in this embodiment, the UE location information may include only the SeNB serving cell information, or the UE location information may include both the MeNB serving cell information and the SeNB serving cell information.

[078] After receiving the E-RAB modification instruction message, in step S203, the MME sends a bearer modification request message that includes the UE location information to the S-GW. In step S204, the S-GW sends, as required, the bearer modification request message that includes the UE location information to the P-GW. After receiving the UE location information, the P-GW sends the UE location information to the PCRF as required, and the PCRF determines a control policy for the UE according to the UE location information. A correspondence between the UE location information and the control policy for the UE can be predefined in the PCRF, and after receiving the UE location information, the PCRF can determine the control policy for the UE. Alternatively, a rule for defining the control policy for the UE can be predefined in the PCRF, and after receiving the location information from the UE, the PCRF can determine the control policy for the UE according to the predefined rule. . The control policy for the UE can include any one or more of a load control policy for the UE, a rate control policy for the UE, a quality of service control policy for the UE, or a priority control for the UE. That is, the PCRF can formulate different control policies for the UE according to the UE location information, so as to control the UE from multiple aspects. After determining the control policy for the UE, the PCRF sends the control policy to a corresponding enforcement entity such as a PCEF or a BBERF, and each enforcement entity performs corresponding control on the UE according to the control policy sent by the UE. PCRF.

[079] It should be noted that if at least two SeNBs simultaneously provide services to the UE, the MeNB need only send serving cell information from any one or more SeNBs to the core network node, or the MeNB can send cell information serving all SeNBs from the UE to the core network node.

[080] In a 3C architecture, since only the MeNB establishes a control plane connection and a user plane data connection with the core network node, when the SeNB needs to provide a service to the UE, the send 12 in the MeNB also needs to report the UE location information to the core network node. However, since there is no bearer between the SeNB and the core network node, the sending module 12 cannot send the UE location information to the core network node using an access bearer modification instruction message. radio. A new control plane message can be defined in this document, which is called a location information update message. The location information update message is used to send the UE location information to the core network node when the UE location information changes. In that case, the serving cell information of the at least one UE SeNB includes: any one or more of a serving cell identification information of the at least one UE SeNB, a quantity of data packets or data packets transmitted in a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE. Alternatively, the serving cell information of the at least one SeNB of the UE includes multi-flow indication information, wherein the multi-flow indication information is used to indicate that at least two access nodes provide services to the UE.

[081] The SAE system is used as an example. In the 3C architecture, a signaling procedure for reporting location information is similar to that of Figure 2, and one difference is only that the E-RAB modification instruction message is changed to the location information update message. Figure 3 is a flowchart of signaling reporting location information using a location information update procedure in an SAE system. As shown in Figure 3, an MME, an S-GW, a P-GW, and a PCRF in the SAE system are collectively called a core network node.

[082] When a SeNB in a network starts serving the UE, a MeNB provides data forwarding to the SeNB, all data packets or data packets sent and received by the SeNB need to be forwarded by the MeNB, and in step S301, the MeNB can obtain serving cell information from the SeNB. The SeNB serving cell information can be any information that can represent a SeNB serving cell serving the UE, for example, any one or more of SeNB serving cell identification information, a number of data packets or data packets transmitted in the SeNB serving cell, a SeNB serving cell's tracking area identity, or an access network type of the SeNB serving cell. Alternatively, the SeNB serving cell information may include multi-flow indication information. A difference between the embodiments shown in Figure 3 and Figure 2 is that the serving cell information of a SeNB of the UE in Figure 2 includes the bearer information corresponding to the serving cell of the SeNB, but the serving cell information of the SeNB of the UE in Figure 2. UE in Figure 3 include the amount of data packets or data packets transmitted in the serving cell of the SeNB. This is due to the fact that the SeNB establishes a bearer with the core network node in Figure 2, and the MeNB can obtain the serving cell information from the SeNB; but there is no bearer between SeNB and core network node in Figure 3, all data packets or data packets from SeNB need to be forwarded by MeNB, and MeNB can only get amount of data packets or data packets transmitted in the SeNB serving cell. Furthermore, the multiflow indication information indicates that at least two access nodes provide services to the UE, i.e. when the MeNB learns that at least one SeNB also serves the UE, the MeNB can determine that the at least two access nodes provide the services to the UE.

[083] In step S302, the MeNB needs to send a location information update message to the MME, and send the UE location information to the MME, and the location information update message is used to send only the location information location of the UE to the MME. In this embodiment, only one MeNB and only one SeNB serves the UE, and MeNB serving cell information can be sent to the MME when the MeNB establishes a bearer with each node in a core network. Therefore, in this embodiment, the UE location information may include only the SeNB serving cell information, or the UE location information may include both the MeNB serving cell information and the SeNB serving cell information.

[084] After receiving the location information update message, in step S303, the MME sends the location information update message that includes the location information of the UE to the S-GW. In step S304, the S-GW sends, as required, the location information update message that includes the location information of the UE to the P-GW. After receiving the UE location information, the P-GW sends the UE location information to the PCRF as required, and the PCRF determines a control policy for the UE according to the UE location information. A correspondence between the UE location information and the control policy for the UE can be predefined in the PCRF, and after receiving the UE location information, the PCRF can determine the control policy for the UE. Alternatively, a rule for defining the control policy for the UE can be predefined in the PCRF, and after receiving the location information from the UE, the PCRF can determine the control policy for the UE according to the predefined rule. . The control policy for the UE can include any one or more of a load control policy for the UE, a rate control policy for the UE, a quality of service control policy for the UE, or a priority control for the UE. That is, the PCRF can formulate different control policies for the UE according to the UE location information, so as to control the UE from multiple aspects. After determining the control policy for the UE, the PCRF sends the control policy to a corresponding enforcement entity such as a PCEF or a BBERF, and each enforcement entity performs corresponding control on the UE according to the control policy sent by the UE. PCRF.

[085] In addition, after receiving the location information update message, the P-GW can further send an acknowledgment message to the S-GW, and after receiving the acknowledgment message, the S-GW can send the receipt confirmation message to the MME.

[086] It should be noted that if at least two SeNBs simultaneously provide services to the UE, the MeNB need only send serving cell information from any one or more SeNBs to the core network node, or the MeNB can send cell information serving all SeNBs from the UE to the core network node.

[087] Another specific method for reporting UE location information is in a 3C architecture. In 3C architecture, since only the MeNB establishes a control plane connection and a user plane data connection with the core network node, when the SeNB needs to provide a service to the UE, the sending module 12 in the MeNB it also needs to report the UE location information to the core network node. However, the forwarding module 12 does not send the UE location information to the core network node using a signaling message in the present document, but sends the UE location information to the core network node using a packet of user plan data. In that case, the serving cell information of the at least one UE SeNB includes: any one or more of a serving cell identification information of the at least one UE SeNB, a quantity of data packets or data packets transmitted in a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE.

[088] The SAE system is used as an example, and the MME, S-GW, P-GW, and PCRF in the SAE system are collectively referred to as the core network node. In the 3C architecture, a first General Packet Radio Tunneling Protocol (GTP-U) user plane packet sent by the MeNB to the S-GW includes the UE location information, where the UE location information they can be in an extension header of the first GTP-U packet; or, a second GTP-U packet sent by the MeNB to the S-GW includes the UE location information, where the second GTP-U packet is a newly added packet, and the packet is used to send the information only location of user equipment. A specific method for obtaining UE location information by a MeNB is the same as that of step S301. After receiving the UE location information using a GTP-U packet, the S-GW sends the UE location information to the P-GW, the P-GW can further send the UE location information to the PCRF, and the PCRF can determine the control policy for the UE according to the location information of the UE. The exchange processes between the S-GW, the P-GW, and the PCRF are similar to those in Figure 2 and Figure 3. The details are not described in this document.

[089] Figure 4 is a schematic structural diagram of embodiment 1 of a core network node according to an embodiment of the present invention. As shown in Figure 4, The core network node in this embodiment includes: a receiving module 41 and a processing module 42.

[090] The receiving module 41 is configured to receive user equipment location information that is sent by a master access node, wherein the user equipment location information includes serving cell information from at least one access node. secondary access of user equipment.

[091] Specifically, all nodes in a core network are collectively called the core network node in this embodiment. For example, for an SAE system, the core network node includes an MME, an S-GW, a P-GW, a PCRF, and the like. The core network node includes the receiver module 41, and the receiver module 41 can be arranged in any core network node as long as the receiver module 41 can receive the UE location information that is sent by the MeNB.

[092] The MeNB in this mode provides a service to the UE, and the at least one SeNB also provides a service to the UE. The UE location information reflects a UE location and, in general, a serving cell coverage area of a MeNB is larger than a serving cell coverage area of a SeNB. Therefore, if the core network node obtains serving cell information from a SeNB serving the UE, a more accurate location of the UE is obtained. Thus, compared to a case where the serving cell information of the MeNB is reported to the core network node, when the serving cell information of the SeNB serving the UE is reported to the core network node, the core network node gets UE location information at a finer granularity.

[093] Therefore, the core network node provided in this embodiment includes the receiving module 41, the receiving module 41 is configured to receive the user equipment location information that is sent by the MeNB, and the UE location information include the serving cell information of the at least one SeNB of the UE. The SeNB serving cell information can be any information that can represent a SeNB resource.

[094] Since there is a control plane connection and a user plane data connection between the MeNB and the core network node, the receiving module 41 can receive the UE location information that is sent by the MeNB by control plane signaling means, or the receiving module 41 can receive the UE location information which is sent by the MeNB using a user plane packet.

[095] Processing module 42 is configured to determine a control policy for user equipment according to user equipment location information.

[096] Specifically, the core network node provided in this embodiment further includes the processing module 42, and the processing module 42 is configured to determine the control policy for the UE according to the location information of the UE. Since the location information of the UE includes the serving cell information of the at least one SeNB of the UE, the processing module 42 can obtain a more accurate location of the UE according to the location information so as to formulate a location policy. control with a finer granularity for the UE.

[097] The processing module 42 can be arranged in any node that is in the core network node and that can determine the control policy for the UE, for example, the PCRF in the SAE system. The PCRF configures different control or loading policies for the UE according to different UE location information, and sends the configured control or loading policies to an enforcement entity such as a PCEF or a BBERF, in order to perform control. correspondent in the EU.

[098] In this embodiment, a MeNB obtains serving cell information from at least one UE SeNB, and sends the information to a core network node, so that the core network node can implement control with a finer granularity over the HUH.

[099] For two architectures in the MSA solution, the core network node shown in Figure 4 performs different specific processing methods, which are described in detail below.

[100] In an 1A architecture, the MeNB and SeNB separately establish a user plane data connection with the core network node, ie, the MeNB and SeNB separately establish a bearer with the core network node. When the SeNB needs to provide a service for the UE, the receiving module 41 in the core network node can receive a radio access bearer modification instruction message sent by the MeNB, and the access bearer modification instruction message by radio includes the location information of the UE. In this way, the UE location information that is sent by the MeNB can be received without a need to exchange an existing signaling procedure. In that case, the serving cell information of the at least one SeNB of the UE includes: any one or more of identifying information of a serving cell of the at least one SeNB of the UE, bearer information that corresponds to a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE.

[101] The SAE system is used as an example, and the MME, S-GW, P-GW, and PCRF in the SAE system are collectively referred to as the core network node. The receiving module 41 is disposed in the MME, and the processing module 42 is disposed in the PCRF. For a specific method to report UE location information, refer to Figure 2.

[102] In a 3C architecture, since only the MeNB establishes a control plane connection and a user plane data connection with the core network node, when the SeNB needs to provide a service to the UE, the receiving 41 in the core network node also needs to receive the UE location information which is reported by the MeNB. However, since there is no bearer between the SeNB and the core network node, in this case, the receiving module 41 cannot receive, using the radio access bearer modification instruction message, the location information of the UE that are sent by the MeNB. A new control plane message can be defined in this document, which is called a location information update message. The location information update message is used to send the UE location information to the core network node when the UE location information changes. In that case, the serving cell information of the at least one SeNB of the UE includes: any one or more of a serving cell identification information of the at least one SeNB of the UE, a quantity of data packets or data packets transmitted in a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE. Alternatively, the serving cell information of the at least one SeNB of the UE includes multi-flow indication information, wherein the multi-flow indication information is used to indicate that at least two access nodes provide services to the UE.

[103] The SAE system is used as an example, and the MME, S-GW, P-GW, and PCRF in the SAE system are collectively referred to as the core network node. The receiving module 41 is arranged in the S-GW, and the processing module 42 is arranged in the PCRF. For a specific method to report UE location information, refer to Figure 3.

[104] Another specific method for reporting UE location information is in a 3C architecture. In the 3C architecture, since only the MeNB establishes a control plane connection and a user plane data connection with the core network node, when the SeNB needs to provide a service to the UE, the receiving module 41 in the node core network can receive, using a user plane data packet, the UE location information that is sent by the MeNB. In that case, the serving cell information of the at least one UE SeNB includes: any one or more of a serving cell identification information of the at least one UE SeNB, a quantity of data packets or data packets transmitted in a serving cell of the at least one SeNB of the UE, a tracking area identity of a serving cell of the at least one SeNB of the UE, or an access network type of a serving cell of the at least one SeNB of the UE.

[105] The SAE system is used as an example, and the MME, S-GW, P-GW, and PCRF in the SAE system are collectively termed the core network node. The receiving module 41 is arranged in the S-GW, and the processing module 42 is arranged in the PCRF. A first GTP-U packet sent by the MeNB includes the UE location information, wherein the UE location information may be in an extension header of the first GTP-U packet; or, a second GTP-U packet sent by the MeNB includes the UE location information, where the second GTP-U packet is a newly added packet, and the packet is used to send only the equipment location information of user.

[106] Figure 5 is a structural schematic diagram of embodiment 1 of a secondary access node according to an embodiment of the present invention. As shown in Figure 5, the secondary access node in this embodiment includes: a get module 51 and a send module 52.

[107] Obtaining module 51 is configured to obtain serving cell information from the SeNB of the UE.

[108] Specifically, the SeNB provided in this modality is applied to a 1A architecture. In architecture 1A, a MeNB and SeNB separately establish a user plane data connection with a core network node, that is, the MeNB and SeNB separately establish a bearer with the core network node. Therefore, both MeNB and SeNB can send a data packet to the core network node. In this way, the core network node can obtain the serving cell information from the SeNB using the data packet sent by the SeNB.

[109] UE location information reflects a UE location and, in general, a coverage area of a serving cell of a MeNB is larger than a coverage area of a serving cell of a SeNB. Therefore, if the core network node obtains serving cell information from a SeNB serving the UE, a more accurate location of the UE is obtained. Thus, compared to a case where the serving cell information of the MeNB is reported to the core network node, when the serving cell information of the SeNB serving the UE is reported to the core network node, the core network node gets UE location information at a finer granularity.

[110] The SeNB includes the acquisition module 51, and the acquisition module 51 is configured to obtain the serving cell information from the SeNB of the UE. The SeNB serving cell information can be any information that can represent a SeNB resource. UE SeNB serving cell information includes: any one or more of a UE SeNB serving cell identification information, bearer information that corresponds to a UE SeNB serving cell, a tracking area identity of a UE SeNB serving cell, or an access network type of a UE SeNB serving cell.

[111] The sending module 52 is configured to: send the UE SeNB serving cell information to a core network node using a first GTP-U packet, where the UE SeNB serving cell information are in an extension header of the first GTP-U packet; or send the UE SeNB serving cell information to a core network node using a second GTP-U packet, wherein the second GTP-U packet is used to send only the UE SeNB serving cell information UE, and the serving cell information of the SeNB is used by the core network node to: after the core network node receives serving cell information from at least one SeNB of the UE, determine a control policy for the UE according to the serving cell information of the at least one SeNB of the UE.

[112] Specifically, after the obtainment module 51 obtains the serving cell information from the SeNB of the UE, the sending module 52 sends the serving cell information to the core network node. An SAE system is used as an example, and the core network node includes an MME, an S-GW, a P-GW, a PCRF and the like. The S-GW establishes a user plane data connection with the SeNB, the sending module 52 can send the SeNB serving cell information from the UE to the S-GW using the first packet of GTP-U, and the S-GW sends the serving cell information from the UE SeNB to the PCRF using the P-GW. The UE SeNB serving cell information is in the extension header of the first GTP-U. Alternatively, the forwarding module 52 may send the serving cell information from the SeNB of the UE to the S-GW using the second packet of GTP-U, where the second packet of GTP-U is a newly added packet, and the second GTP-U packet is used to send the UE SeNB serving cell information only. After receiving serving cell information sent through the at least one SeNB in a network, the PCRF can determine a location of the UE, configure different control or loading policies for the UE according to the location, and send the control or load configured for an executing entity such as a load and policy enforcement function (PCEF) entity or an event reporting and bearer binding (BBERF) function, in order to perform corresponding control in the UE.

[113] Since the core network node determines the location of the UE after receiving the serving cell information from the at least one SeNB of the UE, the core network node can obtain a more accurate location of the UE according to the location information , so that the core network node can formulate a finer-grained control policy for the UE.

[114] In this embodiment, a SeNB sends serving cell information from the UE SeNB to a core network node using a GTP-U packet, so that the core network node can deploy control at a finer granularity over the HUH.

[115] Additionally, in the embodiment shown in Figure 5, the control policy for the UE includes: any one or more of a load control policy for the UE, a rate control policy for the UE, a of quality of service for the UE, or a priority control policy for the UE.

[116] Figure 6 is an embodiment 2 schematic structural diagram of a core network node according to an embodiment of the present invention. As shown in Figure 6, The core network node in this embodiment includes: a receiving module 61 and a processing module 62.

[117] Receiver module 61 is configured to: receive serving cell information from a user equipment SeNB that is sent by the SeNB using a first packet of GTP-U, where the serving cell information from the SeNB of the UEs are in an extension header of the first GTP-U packet; or receiving serving cell information from a UE SeNB that is sent by the SeNB using a second GTP-U packet, wherein the second GTP-U packet is used to send only the serving cell information from the UE SeNB .

[118] Specifically, all nodes in a core network are collectively called the core network node in this embodiment. For example, for an SAE system, the core network node includes an MME, an S-GW, a P-GW, a PCRF, and the like. The core network node includes the receiver module 61, and the receiver module 61 can be disposed in any core network node as long as the receiver module 61 can receive the serving cell information from the SeNB that is sent by the SeNB using if a packet of GTP-U. In the SAE system, the receiving module 61 is arranged in the S-GW.

[119] The UE SeNB serving cell information reflects a UE location and, in general, a coverage area of a serving cell of a MeNB is greater than a coverage area of a serving cell of a SeNB. Therefore, if the core network node obtains serving cell information from a SeNB serving the UE, a more accurate location of the UE is obtained. Thus, compared to a case where the serving cell information of the MeNB is reported to the core network node, when the serving cell information of the SeNB serving the UE is reported to the core network node, the core network node gets UE location information at a finer granularity.

[120] Therefore, the core network node provided in this embodiment includes the receiver module 61, the receiver module 61 is configured to receive the SeNB serving cell information that is sent by the SeNB, and the SeNB serving cell information it can be any information that can represent a SeNB feature.

[121] The receiver module 61 receives the SeNB serving cell information from the user equipment which is sent by the SeNB using the first packet of GTP-U where the SeNB serving cell information of the UE is in the header extension of the first GTP-U. Alternatively, the receiving module 61 receives the SeNB serving cell information from the UE that is sent by the SeNB using the second GTP-U packet, where the second GTP-U packet is a newly added packet, and the second GTP-U packet is used to send the UE SeNB serving cell information only.

[122] The processing module 62 is configured to: after the serving cell information of at least one SeNB of the UE is received, determine a control policy for the UE according to the serving cell information of the at least one SeNB of the UE HUH.

[123] Specifically, the core network node provided in this embodiment further includes the processing module 62, and the processing module 62 is configured to: after the serving cell information of the at least one SeNB of the UE is received, determine the policy of control for the UE. Since the receiving module 61 receives the serving cell information of the at least one SeNB of the UE, the processing module 62 can obtain a more accurate location of the UE according to the serving cell information of the at least one SeNB of the UE, so in order to formulate a control policy with a finer granularity for the UE.

[124] The processing module 62 can be arranged in any node that is in the core network node and that can determine the control policy for the UE, for example, the PCRF in the SAE system. The PCRF configures different control or loading policies for the UE according to different UE location information, and sends the configured control or loading policies to an enforcement entity such as a PCEF or a BBERF, in order to perform control. correspondent in the EU.

[125] In this embodiment, a SeNB sends serving cell information from the UE SeNB to a core network node using a GTP-U packet, so that the core network node can deploy control at a finer granularity over the HUH.

[126] Additionally, in the embodiment shown in Figure 6, the control policy for the UE includes: any one or more of a load control policy for the UE, a rate control policy for the UE, a of quality of service for the UE, or a priority control policy for the UE.

[127] Figure 7 is a flowchart of embodiment 1 of a method for reporting user equipment location information according to an embodiment of the present invention. As shown in Figure 7, the method in this embodiment includes the following steps: Step S701. A master access node obtains user equipment location information, wherein the user equipment location information includes serving cell information of at least one user equipment secondary access node. Step S702. The master access node sends user equipment location information to a core network node, where the location information is used by the core network node to determine a control policy for the user equipment.

[128] The method for reporting user equipment location information in this embodiment is used to complete processing of the master access node shown in Figure 1, and the implementation principles and technical effects thereof are similar. Details are not described in this document.
