Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.

Example one

Fig. 1 is a flowchart of a first embodiment of a near field communication method according to the present invention, which is applicable to communication between near field UEs, in particular, to data interaction based on various local social scenes and game scenes, and is applicable to a calling party in the near field communication, and which may be implemented by cooperation between a UE and a network device (e.g., Mobility Management Entity (MME)), so as to finally establish a direct communication connection between UEs. The UE may be a user equipment such as a smart phone, a tablet computer, and a notebook computer, which has the capability of establishing a Wireless Local Area Network (WLAN), and the communication network may be an LTE network. As shown in fig. 1, the method may be performed according to the following process:

s101, the first user equipment UE receives an instruction of performing close-range communication with the second UE.

In order to implement near field communication, first, a second UE capable of performing near field communication needs to be discovered, where the discovery process may be that the first UE determines a communication object (the second UE) first, and then determines whether the second UE satisfies a condition of near field communication according to identification information of the second UE, or selects the second UE to establish the near field communication from the UEs satisfying the condition of the near field communication, and the discovery process may be completed by establishing a communication link through a network device. The short distance may be a preset distance threshold, and may be set by using the WLAN communication distance of the UE as a reference.

Specifically, the instruction for near field communication may be issued by a user using a first UE by using the first UE, that is, the user autonomously finds that a second UE satisfies a condition for near field communication, such as the user seeing that the user using the second UE is nearby; or the first UE may make the request by using the first UE after determining that the condition is satisfied, which is not limited herein.

S102, the first UE interacts with the second UE through the network equipment, and negotiates configuration information required for establishing WLAN communication connection between the first UE and the second UE.

Specifically, after receiving the instruction of performing close range communication with the second UE, the first UE interacts with the second UE through the network device, and the following method may be adopted:

the first UE sends a WLAN negotiation request to the second UE through the network equipment, and the WLAN negotiation request is used for requesting the second UE to send WLAN configuration information of the second UE to the first UE;

the method comprises the steps that first UE receives WLAN configuration information of second UE sent by the second UE;

the first UE feeds back configuration information for establishing WLAN communication connection between the first UE and the second UE according to the WLAN configuration information of the second UE so as to complete negotiation of the WLAN configuration information required by the establishment of the WLAN communication connection.

The feedback configuration information for establishing the WLAN communication connection between the first UE and the second UE may include a link mode for establishing the WLAN communication connection and identification information of the first UE. The identification information is information that can identify an identity when the WLAN is in communication connection, and may be, for example, a Service Set Identifier (SSID) or a Media Access Control (MAC) address.

Preferably, the following method can also be employed:

the method comprises the steps that first UE sends first configuration information required for establishing WLAN communication connection between the first UE and second UE to the second UE through network equipment; the first configuration information may include a link mode in which the first UE may establish the WLAN communication connection and identification information of the first UE.

And the first UE receives second configuration information which is fed back by the second UE according to the first configuration information and is required for establishing the WLAN communication connection between the first UE and the second UE. The second configuration information may include a link mode for establishing the WLAN communication connection and identification information of the second UE.

Wherein the second configuration information fed back may include a link mode for establishing the WLAN communication connection and identification information of the second UE.

This has the advantage that the number of interactions can be reduced, and the efficiency of WLAN configuration information negotiation can be improved.

The above method is merely illustrative and not limited thereto.

Further, the first configuration information and the second configuration information may include one or a combination of a WLAN link mode, an SSID, a Media Access Control (MAC) address, key information, and a radio channel number, as long as the WLAN communication connection can be established through the first configuration information and the second configuration information, which is not limited herein.

It should be noted that: here, the WLAN configuration information corresponds to the first configuration information, and the configuration information of the WLAN communication connection corresponds to the second configuration information. Meanwhile, various information in the WLAN configuration information, the configuration information of the WLAN communication connection, the first configuration information, and the second configuration information may be sent at one time, or may be sent multiple times, and may be selected according to actual conditions.

The WLAN link mode may include: an Access Point (AP) mode, a Point-to-Point (Adhoc) mode, or a WiFi direct mode, etc.

Optionally, in this step, the network device may include: an Application (App) server or a Mobility Management Entity (MME). The first UE interacts with the second UE through the application server, and negotiates configuration information required for establishing WLAN communication connection between the first UE and the second UE; or the first UE interacts with the second UE through the MME and negotiates configuration information required for establishing the WLAN communication connection between the first UE and the second UE. For example, the first UE sends the WLAN configuration information (i.e., the first configuration information) of the first UE to the application server, and then the WLAN configuration information is transmitted to the second UE by the application server, and then the second UE returns the configuration information (i.e., the second configuration information) of the WLAN communication connection between the first UE and the second UE to the application server, and then the WLAN configuration information is transmitted to the first UE by the application server, thereby completing the interaction.

S103, the first UE establishes WLAN communication connection with the second UE according to the configuration information.

Specifically, after acquiring configuration information required for establishing a WLAN communication connection between the first UE and the second UE, the first UE connects according to a determined link mode of the WLAN to implement direct communication between the first UE and the second UE, and then communication between the first UE and the second UE can be performed by using the WLAN without assistance of a communication network, thereby reducing occupation of spectrum resources of a base station.

In this embodiment, the network device is used to implement negotiation of configuration information required for establishing a WLAN communication connection between the first UE and the second UE, establish a communication connection between the first UE and the second UE, implement direct communication between the UEs in a close range, and solve the problem that spectrum resources of a base station are required to be occupied in a close range communication process.

s201, the first UE receives the identification information of the second UE, which is sent by the application server.

When the first UE and the second UE use the local App, registration information needs to be sent to the application server, and the application server maintains the registration information sent by each UE to form a user information table, where the user information table includes identification information of each UE, and the identification information may include one or any combination of an ID, an IP address, an IMEI code, and the like of the UE.

Specifically, when the first UE uses the local App, the identification information of the second UE may be acquired from the application server, and the acquisition may be performed by the following method:

the method comprises the following steps: the method comprises the steps that first UE selects a friend to be acquired, namely second UE, according to an online friend displayed on a used local App, a request for acquiring identification information of the second UE is sent to an application server, and after the application server receives the request, identification information of the second UE in a user information list maintained by the application server is sent to the first UE.

The second method comprises the following steps: the application server sends all identification information of friends (namely, a plurality of UE establishing association) in a local App of the first UE to the first UE in a user information table maintained by the application server, and the first UE selects the UE to be selected (namely, the second UE) and acquires the identification information of the second UE at the same time.

The above method is merely illustrative and not limited thereto.

S202, the first UE sends a proximity discovery service request containing identification information of the second UE to the MME.

Specifically, in order to determine whether the second UE meets the distance requirement of the proximity communication, the first UE sends a proximity discovery service request to the MME, where the discovery service request carries identification information of the second UE, so that the MME searches for location information of the second UE according to the identification information.

S203, the first UE receives a proximity discovery service response sent by the MME, where the proximity discovery response is sent by the MME after the first UE and the second UE are determined to be in a proximity distance.

In this step, after receiving the discovery service request sent by the first UE, the MME acquires the location relationship between the second UE and the first UE from the local management module according to the identification information of the second UE carried in the discovery request, thereby determining whether the first UE and the second UE are located at the proximity distance, and if so, sends a proximity discovery service response to the first UE. For example, whether the first UE and the second UE belong to the same communication cell (hereinafter, referred to as a cell) may be used as a criterion for determining, by the MME, the proximity distance between the first UE and the second UE.

S204, the first UE finds the second UE capable of performing the short-distance communication according to the short-distance discovery service response so as to determine that the first UE and the second UE can perform the short-distance communication.

Specifically, after receiving the proximity discovery service response sent by the MME, the first UE discovers the second UE through the proximity discovery service response. Wherein the proximity discovery service response may be used to instruct the first UE to wait for scheduling of the base station; the manner of discovering the second UE capable of performing short-range communication may be: after the base station finishes scheduling the first UE and the second UE, the first UE discovers the second UE on the time-frequency resource allocated by the base station.

Preferably, S203 and S204 may be performed according to the following procedure:

and the first UE receives a short-distance discovery service response sent by the MME, wherein the short-distance discovery service response is used for indicating the first UE to wait for scheduling of the base station.

The first UE receives a scheduling message sent by a base station, wherein the scheduling message comprises time-frequency resources and discovery identifiers distributed by the base station for the first UE and the second UE.

And the first UE utilizes the discovery identification to identify whether the received detection information is sent by the second UE.

Specifically, the first UE detects and receives a discovery identifier sent by the second UE on the allocated time-frequency resource, and may determine a communication distance between the first UE and the second UE by using a delay of a signal or an attenuation of the signal of the discovery identifier, so as to further determine whether the communication distance between the first UE and the second UE satisfies a distance range of short-range communication. The proximity discovery service response sent by the MME may be used as a preliminary determination of whether proximity communication is satisfied.

Preferably, S203 and S204 can also be performed according to the following process:

and the first UE receives a near field discovery service response sent by the MME, wherein the near field discovery service response is used for indicating that the scheduling of the base station is immediately executed.

Before the first UE receives the short-range discovery service response sent by the MME, the base station allocates time-frequency resources to the first UE through static or semi-static scheduling.

The first UE receives an indication message sent by a base station, wherein the indication message comprises a discovery identifier.

And the first UE detects and receives the discovery identification sent by the second UE on the allocated time-frequency resources so as to determine that the first UE and the second UE can carry out short-range communication.

Further, after S204, the method may further include: the first UE presents information to the user that the second UE can communicate in close proximity. Specifically, after it is determined that the second UE meets the distance requirement of the close range communication, the result that the second UE can perform the close range communication may be displayed to the user, and meanwhile, the result may be locally stored in the first UE for a period of time, for example, 2 minutes, so that the local other App of the first UE may be reused when requesting the close range discovery of the second UE. Further, on the basis of the method two in S201, a proximity discovery service request may be sent to a plurality of UEs associated with the first UE, and the obtained results of the UEs capable of performing proximity communication are all stored locally and presented to the user, so that the first UE selects a certain UE that is to establish direct communication as the second UE, and meanwhile, the results are reused by other local apps.

According to the embodiment, the discovery of the second UE capable of performing near field communication is completed through the first UE local App and the application server, so that the accurate discovery between the near field communication UEs is realized, and the discovery efficiency of the near field communication is improved.

S402, the second UE returns a proximity distance paging response to the MME so that the MME sends a proximity discovery service response to the first UE and the first UE discovers the second UE according to the proximity discovery service response.

EXAMPLE six

Fig. 6a and fig. 6b are flowcharts of a sixth embodiment of the near field communication method of the present invention, and as shown in fig. 6a or fig. 6b, in this embodiment, on the basis of the fifth embodiment, before the MME receives first configuration information, which is sent by the first UE and is needed to establish the WLAN communication connection between the first UE and the second UE, the method may further include:

s601, the MME receives a proximity discovery service request which is sent by the first UE and contains identification information of the second UE.

In this step, the MME receives the request for proximity discovery service, may record an event of the request for proximity discovery service, and send the event to a charging module corresponding to the core network, for charging the proximity communication service.

S602, the MME determines that the first UE and the second UE are in close proximity.

Specifically, the MME may perform proximity distance paging on the second UE according to the identification information of the second UE, which is carried in the proximity discovery service request sent by the first UE, and determine whether the first UE and the second UE are in a proximity distance according to a paging result. For example, the MME sends a paging request to the second UE according to the identification information of the second UE, and may determine whether the first UE and the second UE belong to a neighboring location of the same cell or an adjacent cell according to the received paging response, if so, it indicates that the first UE and the second UE are in a close distance, and if not, it indicates that the first UE and the second UE are not in a near-field communication enabled range. If the MME does not receive the paging response of the second UE, it may also consider that the first UE and the second UE are not in the range capable of short-range communication.

The proximity distance is a preliminary judgment of whether the first UE and the second UE can perform near field communication, and the near field communication is possible only if the proximity distance is met, otherwise the communication cannot be established. The method has the advantages that the next paging operation is not needed under the condition that the short-distance communication cannot be established, the invalid paging signaling is reduced, and the communication efficiency is improved.

Alternatively, S602 may proceed according to the following procedure:

the MME determines whether the first UE and the second UE are in the same cell;

Optionally, S602 may also proceed according to the following procedure:

the MME acquires a tracking area list of the second UE.

And the MME determines whether the tracking area list contains the cell where the first UE is located.

When the first UE and the second UE are in the same cell, the MME sends a proximity paging request to the second UE.

And the MME receives the proximity distance paging response returned by the second UE.

And the MME determines that the first UE and the second UE are in the close distance according to the close distance paging response.

Specifically, the MME searches the recorded TA list of the second UE from the local management module according to the identification information of the second UE, thereby determining whether the cell where the first UE is located is included in the TA list of the second UE, if so, the MME initiates a proximity distance paging request to the second UE, and determines whether the first UE and the second UE are in a proximity distance according to a proximity distance paging response returned by the second UE. The method has the advantages that if the TA list of the second UE does not contain the cell where the first UE is located, the first UE and the second UE do not meet the distance condition of short-distance communication, paging is not needed, and therefore invalid paging signaling can be reduced, and communication efficiency is improved.

In the embodiment, the discovery process of near field communication is completed through cooperation of the MME, so that accurate discovery between the near field communication UEs is realized, and the discovery efficiency of the near field communication is improved.
