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.
In order to facilitate understanding of the technical solution of the present invention, a network architecture to which the technical solution of the present invention is applied is first illustrated.
Fig. 1 is a schematic diagram of a network architecture applied by the embodiment of the method of the present invention, as shown in fig. 1, the network architecture includes: the core network and the access network, and the communication interface between the core network and the access network is an S1 interface. For the core network, fig. 1 only shows a Mobile Management Entity (MME) and an X Gateway (X Gateway, X-GW), and those skilled in the art will understand that the core network may further include other network elements not shown, such as a Serving GPRS Support Node (SGSN), a Gateway GPRS Support Node (GGSN), and the like. For the access network, only two base stations I-Node and the UEs connected to these two I-nodes, respectively, are shown in fig. 1. Those skilled in the art will appreciate that the access Network may further include a Radio Network Controller (RNC) connected to the base station. The embodiment of the invention can add a new management control unit in the access network, and the management control unit can be deployed on the RNC, a certain base station or an independent entity. The embodiment of the present invention does not limit the specific deployment location of the management control unit in the access network, and it is only necessary to implement the functions of the following management control unit.
Specifically, the management control unit is mainly responsible for implementing a centralized control function of the peer-to-peer communication between the UEs, such as determination of the communication mode between the UEs, addressing of the target base station, sending of control signaling, and the like; the I-Node is an enhanced eNodeB which can support signaling transmission of the mutual communication between the UEs, realize partial control functions, forward service data to a core network under the condition that the mutual communication cannot be realized between the UEs and the like; the UE is an enhanced version of the UE, and can support basic functions such as data transceiving, and report link state information.
The interface 1 between two I-nodes can be connected with two base stations, realizes the control signaling interaction when two UEs communicate with each other under different base stations, and is responsible for forwarding service data and the like under the condition that the communication with each other between the UEs cannot be realized; the interface 2 between the I-Node and the UE is used as a wireless interface to connect the I-Node and the UE in the coverage area thereof, so as to realize the interaction of control signaling, carry out mutual transmission of service data when necessary, and be responsible for reporting local flow and self-charging information, etc.; the interface 3 between the UEs is used as a wireless interface to connect two UEs, thereby realizing the mutual transmission communication of service data and necessary signaling intercommunication, etc.; the interface 4 between the I-Node and the management control unit can be connected with the I-Node and the management control unit to transmit control signaling, such as indication signals of communication modes between the UE, issuing of relevant information of target UE, and the like.
Based on the above example of the network architecture, the following describes the technical solution of the method embodiment of the present invention in detail.
Fig. 2 is a flowchart of an embodiment of a method for mutual communication between user equipments of the present invention, as shown in fig. 2, the method of this embodiment may include:
step 201, the first base station receives a service request message sent by the first UE, and sends the service request message to the management control unit.
In this embodiment, the first UE is the UE1 in fig. 1, the second UE is the UE2 in fig. 1, the first base station is the I-Node1 in fig. 1, the second base station is the I-Node2 in fig. 1, and the management control unit is the management control unit in fig. 1.
Specifically, the UE1 may be an originating UE, and when it needs to perform service data interaction with the UE2 of a destination, it may send a service request message to the I-Node1, where the service request message may include a first identifier of the UE1 and a second identifier of the UE 2.
In the prior art, after receiving the service request message, the I-Node1 directly sends the service request message to the core network, and the sending process may be sending to the RNC, then sending to the X-GW in the core network through the RNC, processing through the core network, and then returning to the I-Node2 in the access network to perform service data interaction with the UE 2. In contrast, in this embodiment, the I-Node1 does not directly send the service request message to the core network, but sends the service data to the management control unit added in fig. 1, so that the management control unit can determine whether the UE1 and the UE2 can perform service data interaction by using the data forwarding transmission method through the interface 3 according to the service request message.
Step 202, the management control unit obtains service characteristics corresponding to the service request message, the first identifier and the second identifier, determines whether the service can perform service data interaction by using a data-to-transmission mode according to the service characteristics, determines whether the service can perform service data interaction by using the data-to-transmission mode between the first UE and the second UE according to the first identifier and the second identifier, and if so, the management control unit sends the service request message to a second base station where the second UE is located and instructs the first base station or the second base station to allocate data bearer resources for the current service data pair.
The management control unit may obtain the corresponding service feature through the service request message, and may also obtain the first identifier and the second identifier included in the service request message. Then, the management control unit may determine whether the service can perform service data interaction by using a data-to-pair transmission method according to the service characteristics, and determine whether the service data interaction between the UE1 and the UE2 can be performed by using the data-to-pair transmission method according to the first identifier and the second identifier.
In specific implementation, the management control unit may pre-store service characteristics suitable for a service implemented by using a data-to-pair transmission method, where such a service may be a local interactive service, for example, a normal data transmission, and may also store identification information of a UE that allows service data interaction using the data-to-pair transmission method. The management control unit can determine whether the service can adopt a data transmission mode to carry out service data interaction only by inquiring the stored white lists.
Specifically, the management control unit may determine whether the UE1 and the UE2 are capable of performing service data interaction by using a data-to-data transmission method by determining whether the first UE and the second UE satisfy at least one of the following conditions:
condition one, whether UE1 and UE2 have data-to-data capability;
the decision of this condition depends on the capabilities of the UE itself used by the user.
And the second condition, whether the UE1 and the UE2 have the authority to carry out data transmission on the service data corresponding to the service features.
The condition is determined according to whether the user opens the data transfer service at the operator.
And a third condition is whether the physical distance between the UE1 and the UE2 is smaller than a preset value.
The condition is determined by whether the UE is powerful enough, and if so, the physical distance is not limited.
It should be noted that, in the above three conditions, if some of the conditions are allowed by default, the management control unit only needs to determine the remaining conditions.
If the management control unit determines that the UE1 and the UE2 can perform the service data interaction of the service in the data-to-data transmission manner after the determination is passed, the management control unit may send the service request message to the I-Node2, so that the I-Node2 may send the service request message to the UE 2.
Moreover, the management control unit may notify the I-Node1 or I-Node2 that the UE1 and the UE2 may perform service data interaction by using a data forwarding transmission method, so as to instruct the I-Node1 or I-Node2 to allocate a data bearer resource for the current service data forwarding.
When the management control unit determines that the UE1 and the UE2 do not satisfy any of the above conditions, the service request message may be sent to the core network, and then the service data interaction is performed in a return manner from the existing access network to the core network and from the core network to the access network.
In a specific implementation, the management control unit may be deployed on the RNC, a certain base station, or as a separate entity. Therefore, if the management control unit is deployed on the RNC or the I-Node1, the management control unit may directly send the service request message to the core network, and if the management control unit is a separately deployed entity that is not an access network element through which the service request message in the prior art is required, the management control unit may instruct the I-Node1 to send the service request message to the core network.
Step 203, the second base station sends the service request message to the second UE.
Step 204, the first base station or the second base station allocates a data bearing resource for the current service data to the opposite, so that the first UE and the second UE transmit the service data on the data bearing resource.
After the I-Node1 or I-Node2 receives the indication of the management control unit, the I-Node1 or I-Node2 may allocate data bearer resources for this service data pair transmission.
For the case that the I-Node1 allocates the data bearer resource for the current service data peer-to-peer, the I-Node1 may send the resource allocation information to the UE1 and the I-Node2, and then the I-Node2 may send the resource allocation information to the UE2, so that the UE1 and the UE2 may establish the direct transmission channel of the interface 3 in fig. 1 according to the resource allocation information and peer-to-peer the service data on the direct transmission channel.
For the case that the I-Node2 allocates the data bearer resource for the current service data peer-to-peer, the I-Node2 may send the resource allocation information to the UE2 and the I-Node1, and then the I-Node1 may send the resource allocation information to the UE1, so that the UE1 and the UE2 may establish the direct transmission channel of the interface 3 in fig. 1 according to the resource allocation information and peer-to-peer the service data on the direct transmission channel.
In this embodiment, after receiving a service request message sent by a first UE through a first base station, a management control unit may determine whether service data interaction can be performed between the first UE and a second UE in a data-to-data transmission manner according to the service request message, and if the data-to-data transmission between the first UE and the second UE can be achieved, the management control unit may forward the service request message to a second base station where the second UE is located, and instruct the first base station or the second base station to allocate bearer resources for the service data-to-data transmission, so that the first UE and the second UE can perform local data-to-data transmission. In the process of this embodiment, for a service that can be implemented by using local data transfer between UEs, it is not necessary to return service data through the core network, but only return the service data in the access network, so that the load pressure of the core network can be relieved to a certain extent.
Fig. 3 is an interaction diagram of establishing bearer and data direct connection between UEs in the embodiment of the method shown in fig. 2, and as shown in fig. 3, this diagram shows a specific implementation process of the first UE and the second UE for transmitting service data on a data bearer resource in step 204 above, it should be noted that this process is only an example and is not limited.
Step 301, the I-Node1 sends the resource allocation information of this service data to UE1 and I-Node 2;
specifically, the I-Node1 may send the resource allocation information of the current traffic data pair to the UE1 via the radio interface 2 in fig. 1, and send the resource allocation information of the current traffic data pair to the I-Node2 via the interface 1. In specific implementation, the I-Node1 may allocate the resource allocation information of the current Service data pair according to a quality of Service (QoS) indicator required for the current Service data transmission.
Step 302, the I-Node2 sends the resource allocation information to the UE 2.
It should be noted that, in this embodiment, the resource allocation information may be, for example, one or more of a timeslot identifier in a time division network, a subchannel identifier in a frequency division network, a code channel identifier in a code division network, or a resource block identifier in a Long Term Evolution (LTE) network. Optionally, the resource allocation information may also include link configuration information, such as power, an identifier of a coding modulation mode, and the like, and may be, for example, a certain channel coding scheme or a modulation mode at a certain code rate.
Step 303, the UE1 sends request information to the UE 2.
In particular, the UE1 may send request information on the allocated resources to the UE2, the request information being used to establish a radio bearer between the UE1 and the UE 2. Alternatively, the timer may also be started simultaneously. The request information may be a sequence of agreed formats, which may include identification of the UE1 and the UE2, and the like.
Step 304, the UE2 feeds back ack information to the UE 1.
After receiving the request information, the UE2 may return ack information to the UE1, thereby implementing the handshaking procedure between the UE1 and the UE 2.
Step 305, UE1 and UE2 perform service data interaction.
Specifically, the UE1 and the UE2 may interact with data based on the established radio bearer. The procedure of establishing the radio bearer may be implemented according to procedures of establishing radio bearers specified in various communication standards, such as LTE or High Speed Uplink packet access (HSPA).
In addition, if the timer is started, the UE1 may retransmit the request information if the UE1 has not received ack information for the UE2 and has not reached the maximum number of times the request information is transmitted after the timer expires.
Step 306, the UE1 sends a resource release request to the I-Node 1.
After the UE1 and UE2 complete traffic data transmission, the UE1 may send a resource release request to the I-Node1 to release the allocated data bearer resources.
Step 307, the I-Node1 sends the resource release request to the management control unit.
Step 308, the management control unit sends a resource release indication message to the I-Node 1.
The I-Node1 releases the allocated data bearing resource after receiving the resource release indication message.
It should be noted that fig. 3 only shows the process of releasing data bearer resources after the I-Node1 allocates data bearer resources, and for the process of releasing data bearer resources after the I-Node2 allocates data bearer resources, the I-Node2 receives a resource release request message sent by the second UE and sends the resource release request message to the management control unit; the management control unit sends a resource release indication message to the I-Node 2; the I-Node2 releases the allocated data bearer resources.
The above embodiments are only described by taking the scenario that the UE1 and the UE2 are in different I-nodes as an example, and those skilled in the art can understand that, if the UE1 and the UE2 are in the same I-Node, the I-Node1 and the I-Node2 shown in fig. 1 are the same I-Node 2.
