Embodiment 1

[0083] Figure 5 It is a schematic diagram of MME obtaining eNB positioning capability when S1 is established, Figure 6It is a schematic diagram of MME obtaining eNB positioning capability when S1 is updated. As shown in the figure, in the process of obtaining eNB positioning capability, MME can add eNB in ​​S1SETUP REQUEST (S1 establishment request) message or ENBCONFIGURATION UPDATE (eNB configuration update) message The optional information element positioning capability carries the positioning capability of the eNB, so that the eNB can notify the MME of its positioning capability when S1 is established or when S1 is updated. The MME stores it after receiving it, and can determine the positioning capability of the eNB directly from the positioning capabilities of the subordinate eNBs stored by the MME when executing step 402 later.

Embodiment 2

[0085] Figure 7 It is a schematic diagram of obtaining the eNB positioning capability through OAM. As shown in the figure, in the process of obtaining the eNB positioning capability, the MME can maintain the positioning capability information of each eNB when the eNB is started, restarted, or the eNB positioning capability changes. The positioning capability of the eNB notifies the MME. The MME stores it after receiving it, and can determine the positioning capability of the eNB directly from the positioning capabilities of the subordinate eNBs stored by the MME when executing step 402 later.

[0086] 2. The implementation of the positioning capability of the interactive eNB between the MME and the E-SMLC in various positioning procedures, and the implementation of the positioning capability of the interactive eNB between the SLP and the E-SMLC.

[0087] In the process of exchanging eNB positioning capability information between MME and E-SMLC, the following scenarios will b...

Embodiment 3

[0097] Figure 8 It is a schematic diagram of the eNB positioning capability notification during the control plane positioning initiation process. As shown in the figure, when the eNB positioning capability is notified during the control plane positioning initiation process, the following steps may be included:

[0098] Step 801, sending a positioning service request to the MME;

[0099] In this step, regardless of whether it is MO-LR, MT-LR or NI-LR, the final client will send a positioning service request to the MME;

[0100] Step 802, triggering a Service Request (service request); in the case of MO-LR and NI-LR, when sending a positioning service request to the MME, the UE is already connected to the MME, so this step does not need to be performed; in the case of MT-LR , when sending a positioning service request to the MME, the UE may be in the ECM-IDLE state. At this time, the network side needs to trigger a ServiceRequest, establish a connection with the UE, and determ...

Abstract

The invention discloses a method and equipment for notifying the positioning capability of an evolved base station, comprising: a mobility management entity determines the current serving evolved base station of the user equipment; and determines in the positioning capability of the evolved base station subordinate to the mobility management entity The positioning capability of the current serving eNB of the user equipment; the mobility management entity notifies the evolved serving mobile location center of the positioning capability of the current serving eNB of the user equipment. The invention ensures that the evolution service mobile location center can fully obtain the location capability of each node participating in the location, and then select a suitable location method. At the same time, the mobility management entity notifies the evolved serving mobile location center of the positioning capability of the current serving eNB, which also reduces the signaling interaction between the eNB and the evolved serving mobile location center.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and equipment for notifying positioning capability of an evolved base station. Background technique [0002] figure 1 It is a schematic diagram of the positioning architecture of E-UTRAN (Evolution-Universal Terrestrial Radio Access Network, evolved global terrestrial radio access network), and the positioning architecture related to E-UTRAN is shown in the figure. The architecture supports both control plane positioning and user plane positioning. During the positioning process of the control plane, the target device is UE (User Equipment, user equipment), and the server on the network side is E-SMLC (Evolved Serving Mobile Location Centre, evolved service mobile location center). The information exchange between eNB (evolved base station), MME (Mobility Management Entity, mobility management entity) and E-SMLC completes the positioning function of the termin...
