Embodiment 1
[0157] Preferred embodiment one, PDCP packet format carrying ProSe communication data
[0158] Figure 18 , Figure 19 It is a schematic diagram of the format of the PDCP data packet used for ProSe communication in the preferred embodiment of the present invention. Compared with the PDCP data packet of the user plane in the related art, the following improvements are made: In the header field of the PDCP data packet, there is the following information: neighbor communication indication ( ProSe ID): The PDU Type (that is, the 3-bit R reserved bit) part is set as the ProSe indicator bit, which can take the value in 010-111, typically, it can be set to 111; the receiving / sending terminal ID (Target / Source UE ID ), including: receiving terminal ID (Target UE ID): used to indicate the ID of the receiving terminal, the length can be set according to the network conditions, typically can be set to 16 bits. Sending terminal ID (Source UE ID): used to indicate the ID of the source te...
Embodiment 2
[0171] Preferred embodiment 2, eNodeB locally routes PDCP packets carrying ProSe communication data
[0172] use Figure 18 , 19 In the method for constructing a PDCP packet, the sending terminal can send to the eNodeB and receive from the eNodeB a PDCP packet carrying ProSe data (that is, a PDCP packet whose header field includes a ProSe indication and the ID of the receiving / sending terminal).
[0173] different from Figure 16 In the above process, the eNodeB allocates specific ProSe communication resources for UE1 and UE2 for neighbor communication (that is, requests to allocate PC5 air interface resources). In this embodiment, the UE can use the established EPS bearer and wireless DRB bearer, To send / receive PDCP packets carrying ProSe data.
[0174] Specifically, when the sending terminal (Source UE) wants to send ProSe data to the receiving terminal (Target UE), the sending terminal constructs a PDCP packet, and carries the ProSe indication, the ID of the receiving t...
Embodiment 3
[0201] Preferred embodiment 3, eNodeB routes PDCP packets carrying ProSe communication data to the superior
[0202] Figure 21 It is a flow chart of the base station according to the preferred embodiment of the present invention to route up the PDCP packets carrying the ProSe communication data, such as Figure 21 As shown, when the UE at the sending end and the UE at the receiving end are not under the same eNodeB, the eNodeB extracts the IP data in the PDCP packet carrying the ProSe data, and routes the IP data to the upper level, including the following steps:
[0203] Step S2101~step S2102, such as Figure 20 As shown in steps S2001 to S2002, UE1 sends a PDCP data packet carrying ProSe data;
[0204] Step S2103, after eNodeB1 receives the PDCP packet carrying ProSe data sent by UE1, it judges that UE2 is not under the eNodeB according to the receiving terminal ID (ie UE2ID), and decides to route to the upper layer;
[0205] Step S2104, eNodeB1 extracts the IP data pack...
