Abstract: An Internet Protocol (IP) address allocation method and a device to resolve a technical problem that an IP address conflict occurs when a control plane device and a user plane device allocate an IP address for one user equipment (UE) at the same time. When receiving a session establishment request message, a control plane network device may determine whether a first user plane network device is capable of allocating an IP address for a terminal device. If the first user plane network device is capable of allocating the IP address for the terminal device, the control plane network device may send an address allocation indication to the first user plane network device.

Abstract: The present invention relates to the communications field and provides a group communication method. The method includes: obtaining location information of UE; when determining that an L-BM-SC is deployed at a location of an eNB to which the UE belongs, determining, according to the location information of the UE, an MCE that manages the eNB to which the UE belongs; and sending a first bearer activation request to the MCE, where the first bearer activation request includes the location information of the UE, so that the MCE determines, according to the location information of the UE, a first L-BM-SC deployed at the location of the eNB to which the UE belongs, and establishes a bearer between the first L-BM-SC and a GCS AS, where the bearer between the first L-BM-SC and the GCS AS is used by the GCS AS to send a packet to the first L-BM-SC.
