Description

Device-to-device authorization information configuration method and device and network element device

Technical Field

The invention relates to a mobile communication technology, in particular to a Device-to-Device (D2D) authorization information configuration method, a Device-to-Device authorization information configuration Device and a network element Device.

Background

With the development of wireless multimedia services, the demand for high data rate and user experience is increasing, and thus higher requirements are placed on the system capacity and coverage of the conventional cellular network. The popularity of social networking, close-range data sharing, local advertising, and like applications, on the other hand, has increased the need for people to know and communicate with people or things of interest nearby, such as proximity services. Against the background of the demand for high data rates and support of Proximity Services (Proximity Services) in conventional base station centric cellular networks, D2D technology representing a new direction for future communication technology development has emerged. The application of the D2D technology can reduce the burden of the cellular network, reduce the battery power consumption of the user equipment, increase the data rate, and improve the robustness of the network infrastructure, and well meet the requirements of the high data rate service and the proximity service.

In the third Generation Partnership Project (3 GPP) architecture, network elements related to D2D services mainly include: a terminal, also referred to as User Equipment (UE); the base station, also called an evolved node b (eNB) in an evolved system, mainly serves to provide radio resources for access of the terminal, and simultaneously interworks with a mobile management unit of a core network through an S1 interface. The core network provides non-access stratum management, and the Prose server provides functions of registration authorization of the D2D service and the like. The service authorization process is completed by the terminal through a PC3 interface of a Prose Function (Prose Function) of the Prose server, and authorization information is based on a Public Land Mobile Network (PLMN); therefore, a terminal authorized in a certain PLMN does not necessarily obtain authorization in another PLMN.

In the prior art, multiple PLMN (multiple PLMN) scenarios are supported, for example, for a single UE, the UE may reside in multiple networks, and a Public Land Mobile Network (PLMN) list supported by the UE is called an Equivalent PLMN list (EPLMN list). Although the UE may camp on or establish a connection in the equivalent PLMN list network, since the authorization of the D2D service is PLMN-based, the terminal is not allowed to use the D2D service in case of unauthorized PLMN camping. The base station supporting the D2D function needs to perform authorization check on the D2D service request sent by the terminal, and also needs to check whether the switched PLMN satisfies the authorization of the UE during the handover process. However, in the existing protocol, how to configure the D2D authorization information when the base station supports multiple PLMN scenarios is not considered, that is, in the prior art, the D2D authorization function cannot support multiple PLMN scenarios.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a flowchart illustrating a method for configuring D2D authorization information according to an embodiment of the present invention; as shown in fig. 1, the D2D authorization information configuration method includes:

step 101: a core network element acquires D2D authorization permission range indication information of a terminal; wherein the D2D authorization permission range indication information characterizes the PLMN which is authorized by the terminal to support D2D service.

Here, the core network element may be a Mobility Management Entity (MME).

Specifically, in a Long Term Evolution (LTE) network, the MME may obtain authorization information of the terminal from a Home Subscriber Server (HSS) through a HSS device interface, where the authorization information may include whether the D2D service is allowed to be used under a PLMN where the terminal is currently located, that is, authorization indication information; also includes whether the terminal allows using D2D service under other PLMN; wherein the information of all PLMNs allowed by the terminal to use the D2D service authorizes the D2D of the terminal with the permission range indication information.

Specifically, whether the terminal allows the D2D service to be used under other PLMNs may be implemented by allowing a PLMN list of the D2D service; in the following embodiments, the D2D traffic may include: D2D Direct communication (DirectCommunication) and D2D Direct Discovery (Direct Discovery) services.

In the embodiment of the present invention, the D2D service may operate in a licensed frequency band or an unlicensed frequency band, and a plurality of User equipments supporting the D2D function, that is, D2D User equipments (D2D UEs, D2D User Equipment) are allowed to perform the D2D service in the presence of a network infrastructure or in the absence of a network infrastructure. D2D traffic generally includes: D2D discovery technology and D2D communication technology; among them, the D2D discovery technology refers to a technology for determining/confirming that two or more D2D user equipments are adjacent to each other (e.g., within a direct D2D communication range) or for determining or confirming that a first user equipment is adjacent to a second user equipment. Generally, the D2D ues can discover each other by sending or receiving discovery signals/information, and under the coverage of cellular network, the network can assist the D2D ues in D2D discovery; the D2D communication technology refers to a technology in which some or all of communication data between D2D user devices may be communicated directly without passing through a network infrastructure.

The terminals in the adjacent area can bring many benefits to the terminals by using the D2D direct communication, such as higher speed, lower delay and less power consumption, and simultaneously, the radio resource efficiency of the operator is also greatly improved, and the Relay mode of D2D is beneficial to the operator to improve the radio coverage; for application, new attractive services can be developed by using the proximity information in the D2D communication process. Public Safety (Public Safety) systems may also utilize D2D technology to enable communication between terminals without wireless coverage.

The D2D Discovery technology may be divided into two different modes, one mode is Direct Discovery (Direct Discovery) of D2D, and the other mode is an Evolved Packet network (EPC) mode, that is, geographical location information of each terminal is stored through a Core network, and a D2D Discovery function is further provided according to the information.

For the transmission of D2D direct communication and the transmission of D2D direct discovery, according to the resource allocation method, it can be further divided into two methods; for the transmission of D2D direct communication, divided into Mode one (Mode1) and Mode two (Mode 2); the mode one refers to a base station scheduling resource; the mode two refers to that the UE autonomously selects resources; for the transmission found by D2D, it is divided into type one (type 1) and type two (type 2); the type one mode refers to that the resource allocation process is not allocated according to the granularity of a certain UE; the type two mode refers to that the resource allocation process is allocated according to the granularity of the UE.

Preferably, the D2D authorized permission range indication information includes at least one of the following information: a PLMN authorized by transmission (transmission) characterizing D2D Direct Communication (Direct D2D Communication) allowed to be supported by the terminal, a PLMN authorized by acceptance (reception) characterizing D2D Direct Communication allowed to be supported by the terminal, a PLMN authorized by transmission (arrival) characterizing D2D Direct Discovery (Direct D2D Discovery) allowed to be supported by the terminal, a PLMN authorized by listening (monitor) characterizing D2D Direct Discovery (Direct D2D Discovery) allowed to be supported by the terminal; wherein, the above-mentioned PLMN characterized can be realized through PLMN tabulation; specific examples thereof include: the PLMN(s) characterizing sending (transmission) authorization of D2D Direct Communication (Direct D2D Communication) allowed to be supported by the terminal may be implemented by a list of PLMNs characterizing sending (transmission) authorization of D2D Direct Communication (Direct D2D Communication) allowed to be supported by the terminal.

Preferably, the D2D authorized permission range indication information includes: PLMNs characterizing the resource types used by the terminal to allow the sending (transmission) authorization of the D2D direct communications supported, such as the authorized allowed range for Mode one (Mode1) and the authorized allowed range for Mode two (Mode 2); PLMNs that characterize the resource types used by the D2D direct discovery allowed by the terminal to send (announce) grants, such as grant permission scope of type one (type 1) and grant permission scope of type two (type 2).

Step 102: and the core network element configures the D2D authorized allowable range indication information to a radio access network element.

Here, the radio access network element may be an eNB.

The core network element may configure the D2D authorized allowable range indication information to a radio access network element through an interface message;

Wherein, the configuring, by the core network element, the D2D authorized allowable range indication information to the radio access network element includes:

Specifically, in the process of sending the D2D authorization indication information and the D2D authorization permission range indication information through the interface message, the D2D authorization permission range indication information and the D2D authorization indication information may be combined in one field of the interface message or may be independent in one field. The merging in one field means that the D2D authorization indication information is added in the authorization indication field of the interface message, that is, PLMN list information that the terminal allows to use D2D services is added. The independent field means that two fields are simultaneously carried in the same message body, one field is used for carrying the authorization indication information, and the other field is used for carrying the D2D authorization permission range indication information.

In this embodiment, before the core network element configures the D2D authorized allowable range indication information to the radio access network element, the method further includes:

Specifically, for example, when the core network element is an MME and the radio access network element is an eNB, before the MME configures the D2D authorized allowable range indication information to the eNB, the MME obtains, through an interface message, indication information of whether the eNB supports a D2D function, and stores the indication information; here, the MME queries the stored indication information, determines whether the eNB supports the D2D function, and configures the D2D authorized allowable range indication information to the eNB when it is determined that the eNB supports the D2D function.

Preferably, the radio access network element receives the D2D authorized permission range indication information configured by the core network element, and implements the D2D service of the terminal according to the PLMN of the terminal authorized to support the D2D service in the D2D authorized permission range indication information.

The following describes the method for configuring D2D authorization information in detail with specific embodiments.

Example one

In this embodiment, a method for configuring D2D authorization information is further described in detail by taking a UE accessing a network as an example. Fig. 2 is a flowchart illustrating a method for configuring D2D authorization information according to a first embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

step 21: when the eNB and the MME establish S1 linkage or after the eNB and the MME establish S1 linkage, the eNB sends indication information whether the D2D function is supported or not to the MME.

Here, one way to transmit the indication information supporting the D2D function to the MME is that when the eNB and the MME establish an S1 link, specifically, the eNB transmits an S1SETUP REQUEST (S1SETUP REQUEST) message to the MME, and the S1SETUP REQUEST carries the indication information whether the eNB supports the D2D function; and the MME receives and stores the indication information.

Another way to send the indication information supporting the D2D function to the MME is that, after the eNB and the MME establish an S1 link, the eNB sends a base station CONFIGURATION UPDATE (eNB CONFIGURATION UPDATE) message to the MME, where the base station CONFIGURATION UPDATE message carries the indication information whether the eNB supports the D2D function, and the MME receives and stores the indication information.

Step 22: UE initiates a Radio Resource Control (RRC) connection establishment flow in a cell under an eNB to complete establishment of wireless connection; the current Serving PLMN (or Serving PLMN, or RPLMN) of the UE is denoted as PLMN 1.

Step 23: the eNB sends an Initial UE Message (Initial UE Message) to the MME.

Step 24: MME obtains authorization information of the UE from HSS.

Here, the MME may obtain authorization information of the terminal from the HSS through an HSS device interface, where the authorization information may include whether the terminal is allowed to use a D2D service under a PLMN where the terminal is currently located, and may also include whether the terminal is allowed to use a D2D service under another PLMN; specifically, whether the terminal allows the D2D service to be used under other PLMNs may be implemented by allowing a PLMN list of the D2D service; wherein the D2D service includes: D2D direct communication or D2D direct discovery, etc.

Step 25: an MME sends an Initial UE Context establishment Request (Initial UE Context Setup Request) message to an eNB, wherein the Initial UE Context establishment Request message carries D2D authorization permission range indication information of the UE.

Here, the MME queries the stored indication information of whether the eNB supports the D2D function, and determines whether the eNB supports the D2D function; when the judgment result shows that the eNB supports the D2D function, carrying D2D authorization indication information of the UE and D2D authorization permission range indication information of the UE in the initial UE context establishment request message, wherein the D2D authorization permission range indication information comprises PLMN list information allowing D2D service; after receiving the initial UE context establishment request message, the eNB stores D2D authorization permission range indication information of the UE, which is carried in the initial UE context establishment request message;

and when the judgment result shows that the eNB does not support the D2D function, the initial UE context establishment request message does not carry the D2D authorization indication information of the UE, and does not carry the D2D authorization permission range indication information of the UE.

The D2D authorization indication information of the UE is specifically authorization information that the UE allows to use D2D service in the current serving PLMN (PLMN 1); the D2D authorized license scope indication information of the UE is information of all PLMNs that the UE allows to use D2D service, including the current serving PLMN (i.e., PLMN 1).

Wherein, in transmitting the D2D granted indication information and the D2D granted permission range indication information through the initial UE context setup request message, the D2D granted permission range indication information may be combined with the D2D granted indication information in one field or may be independent in one field. The merging in one field means that PLMN list information that the terminal allows to use the D2D service is added in the authorization indication field of the initial UE context setup request message. The independent field means that two fields are simultaneously carried in the same message body, one field is used for carrying the authorization indication information, and the other field is used for carrying the D2D authorization permission range indication information; wherein the message body is, for example, the initial UE context setup request message in this embodiment.

In this embodiment, the initial UE context setup request message simultaneously carries the D2D authorized permission range indication information and the D2D authorization information; preferably, the initial UE context setup request message may also only carry the D2D authorization permission range indication information, that is, D2D services are allowed to be used by default in a network specified by an authorization range, in which case the D2D authorization indication information may be omitted from the initial UE context setup request message.

Specifically, the D2D authorized license scope indication information may be an index or bitmap information of a PLMN having an authorized license, and an object of the index or bitmap may be an equivalent PLMN list supported by the UE, for example; or may be a list of all PLMNs supported by the eNB; the eNB can find corresponding PLMN identification information according to the index or the bitmap. For example, the equivalent PLMN list supported by the UE and/or PLMNs indicated by all PLMN lists supported by the eNB include: PLMN1, PLMN2, and PLMN 3.

Step 26: and the eNB initiates an RRC connection reconfiguration flow to the UE to complete the establishment of the radio bearer.

Step 27: the eNB sends an Initial UE message Response (Initial UE message Response) message to the MME to complete the context establishment of the UE.

Example two

In this embodiment, a first scenario that the UE is switched from the source base station to the target base station is taken as an example, and the method for configuring the D2D authorization information is further described in detail. Fig. 3 is a flowchart illustrating a method for configuring D2D authorization information according to a second embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

step 31: when a source eNB and a target eNB establish S1 linkage with an MME respectively or after the source eNB and the target eNB establish S1 linkage with the MME respectively, the source eNB and the target eNB send indication information supporting D2D functions to the MME.

Here, one way of sending the indication information supporting the D2D function to the MME is that when the source eNB and the target eNB establish an S1 link with the MME, respectively, specifically, when the source eNB and the target eNB send an S1SETUP REQUEST (S1SETUP REQUEST) message to the MME, respectively, and the S1SETUP REQUEST carries the indication information whether the source eNB and the target eNB support the D2D function, respectively; the MME receives and stores the indication information of the source eNB and the target eNB.

Another way of sending the indication information supporting the D2D function to the MME is that after the source eNB and the target eNB establish S1 links with the MME, when the source eNB and the target eNB send base station CONFIGURATION UPDATE (eNB CONFIGURATION UPDATE) messages to the MME, the base station CONFIGURATION UPDATE messages carry indication information of whether the source eNB and the target eNB support the D2D function, respectively, and the MME receives and stores the indication information of the source eNB and the target eNB.

Step 32: the source eNB sends a HANDOVER request (HANDOVER requested) message to the MME.

Step 33: MME obtains authorization information of the UE from HSS.

Step 34: MME sends a Handover REQUEST (HANDOVER REQUEST) message to the target eNB; the handover requirement message carries D2D authorized permission range indication information of the UE.

Here, the MME queries the stored indication information of whether the D2D function is supported, and determines whether the target eNB supports the D2D function; when the judgment result shows that the target eNB supports the D2D function, carrying D2D authorization indication information of the UE and D2D authorization permission range indication information of the UE in the handover requirement message, wherein the D2D authorization permission range indication information comprises PLMN list information allowing D2D service; after receiving the handover requirement message, the target eNB stores D2D authorized permission range indication information of the UE, wherein the D2D authorized permission range indication information is carried in the handover requirement message;

and when the judgment result shows that the target eNB does not support the D2D function, the handover requirement message does not carry the D2D authorization indication information of the UE, and does not carry the D2D authorization permission range indication information of the UE.

Wherein, in the process of transmitting the D2D authorization indication information and the D2D authorization permission range indication information through the handover requirement message, the D2D authorization permission range indication information may be combined with the D2D authorization indication information in one field or may be independent in one field. The merging in one field means that PLMN list information allowing the D2D service is added in the authorization indication field of the handover required message. The independent field means that two fields are simultaneously carried in the same message body, one field is used for carrying the authorization indication information, and the other field is used for carrying the D2D authorization permission range indication information; the message body is, for example, the handover required message in this embodiment.

In this embodiment, the handover request message simultaneously carries the D2D authorized permission range indication information and the D2D authorization information; preferably, the handover requirement message may also only carry the D2D authorized permission range indication information, that is, the D2D service is allowed to be used by default in the network specified by the authorized range, in which case the D2D authorized indication information may be omitted from the handover requirement message.

Specifically, the D2D authorized license scope indication information may be an index or bitmap information of a PLMN having an authorized license, and an object of the index or bitmap may be an equivalent PLMN list supported by the UE, for example; or may be a list of all PLMNs supported by the target eNB; the target eNB can find corresponding PLMN identification information according to the index or the bitmap.

Step 35: the target eNB sends a HANDOVER REQUEST feedback (HANDOVER ACKNOWLEDGE) message to the MME.

Step 36: the MME sends a Handover request (HandOVER COMMAND) message to the source eNB to complete the HANDOVER process of the UE from the source base station to the target base station.

EXAMPLE III

In this embodiment, a second scenario in which the UE is switched from the source base station to the target base station is taken as an example, and the method for configuring the D2D authorization information is further described in detail. Fig. 4 is a flowchart illustrating a method for configuring D2D authorization information according to a third embodiment of the present invention, as shown in fig. 4, the method includes the following steps:

step 41: when a source eNB and a target eNB establish S1 linkage with an MME respectively or after the source eNB and the target eNB establish S1 linkage with the MME respectively, the source eNB and the target eNB send indication information supporting D2D functions to the MME.

Step 42: the source eNB sends a HANDOVER REQUEST (HANDOVER REQUEST) message to the target eNB over the X2 interface.

Step 43: the target eNB returns a HANDOVER REQUEST feedback (HANDOVER REQUEST ACK) message to the source eNB over the X2 interface.

Step 44: the target eNB sends a path update REQUEST (PATH SWITCH REQUEST) message to the MME.

Step 45: MME obtains authorization information of the UE from HSS.

Step 46: and the MME sends a path update REQUEST response (PATH SWITCH REQUEST ACKNOWLEDGE) message to the target eNB, wherein the path update REQUEST response message carries the D2D authorized permission range indication information of the UE.

Here, the MME queries the stored indication information of whether the D2D function is supported, and determines whether the target eNB supports the D2D function; when the judgment result shows that the target eNB supports the D2D function, carrying D2D authorization indication information of the UE and D2D authorization permission range indication information of the UE in the path updating request response message, wherein the D2D authorization permission range indication information comprises PLMN list information allowing D2D service; after receiving the path updating request response message, the target eNB stores D2D authorization permission range indication information of the UE, wherein the D2D authorization permission range indication information is carried in the path updating request response message;

and when the judgment result shows that the target eNB does not support the D2D function, the path updating request response message does not carry the D2D authorization indication information of the UE, and does not carry the D2D authorization permission range indication information of the UE.

Wherein, in the process of transmitting the D2D authorization indication information and the D2D authorization permission range indication information through the path update request response message, the D2D authorization permission range indication information may be combined with the D2D authorization indication information in one field or may be independent in one field. The merging in one field means that PLMN list information allowing the D2D service is added in the authorization indication field of the path update request response message. The independent field means that two fields are simultaneously carried in the same message body, one field is used for carrying the authorization indication information, and the other field is used for carrying the D2D authorization permission range indication information; the message body is, for example, the path update request response message in this embodiment.

In this embodiment, the path update request response message simultaneously carries the D2D authorized permission range indication information and the D2D authorization information; preferably, the path update request response message may also only carry the D2D authorization permission range indication information, that is, D2D service is allowed to be used by default in a network specified by an authorization range, and at this time, the D2D authorization indication information may be omitted from carrying in the path update request response message.

Example four

In this embodiment, taking the UE accessing the femtocell network as an example, the D2D authorization information configuration method is further described in detail. Fig. 5 is a flowchart illustrating a D2D authorization information configuration method according to a fourth embodiment of the present invention, as shown in fig. 5, the method includes the following steps:

step 51: UE initiates a Radio Resource Control (RRC) connection establishment flow in a cell under an eNB to complete establishment of wireless connection; namely, the UE initiates an RRC connection establishment flow to a home base station (HeNB) to complete the establishment of wireless connection; the current Serving PLMN (or Serving PLMN, or RPLMN) of the UE is denoted as PLMN 1.

Step 52: the HeNB sends an Initial UE Message (Initial UE Message) to a home base station gateway (HeNB GW).

Step 53: the HeNB GW sends an Initial UE Message (Initial UE Message) to the MME.

Step 54: MME obtains authorization information of the UE from HSS.

Step 55: MME sends an Initial UE Context Setup Request (Initial UE Context Setup Request) message to HeNB GW; the initial UE context setup request message carries information indicating the D2D authorized allowable range of the UE.

Here, the MME carries, in the initial UE context setup request message, D2D authorization indication information of the UE, and simultaneously carries D2D authorization permission range indication information of the UE, where the D2D authorization permission range indication information includes PLMN list information for allowing D2D services; and after receiving the initial UE context establishment request message, the HeNB GW stores the D2D authorization permission range indication information of the UE carried in the initial UE context establishment request message.

The D2D authorization indication information of the UE is specifically authorization information that the UE allows to use D2D service in the current serving PLMN (PLMN 1); the D2D authorized license scope indication information of the UE is information of all PLMNs that the UE allows D2D service, including the current serving PLMN (i.e., PLMN 1).
