A method performed by a base station for obtaining terminal information, comprising: receiving, when a subscriber is registered or terminal information is changed, service policy information sent by an element management server, EMS, wherein the service policy information comprises a mapping relationship between terminal information and subscriber profile IDs, SPIDs, wherein the mapping relationship between terminal information and subscriber profile IDs SPIDs comprises a first mapping table that maps terminal information and terminal priority indicators, and a second mapping table that maps SPIDs, operator-defined SPIDs and terminal priority indicators; obtaining (504, 505) a first SPID corresponding to a first terminal; wherein the obtaining the first SPID comprises receiving the first SPID sent by a mobility management entity, MME, wherein the first SPID is sent by a home subscriber server, HSS, to the MME; learning an existing policy according to the operator-defined SPID, wherein the operator-defined SPID is obtained by mapping the first SPID to the operator-defined SPID in the second mapping table; and obtaining (506, 507) according to the service policy information and the first SPID, terminal information of the first terminal, and wherein the base station obtains the terminal information of the first terminal by mapping the first SPID to a terminal priority indicator and mapping the terminal priority indicator to terminal information in the mapping tables; wherein the terminal information comprises one of or a combination of the following information: a terminal supplier, a terminal model, and a terminal operating system. receiving, when a subscriber is registered or terminal information is changed, service policy information sent by an element management server, EMS, wherein the service policy information comprises a mapping relationship between terminal information and subscriber profile IDs, SPIDs, wherein the mapping relationship between terminal information and subscriber profile IDs SPIDs comprises a first mapping table that maps terminal information and terminal priority indicators, and a second mapping table that maps SPIDs, operator-defined SPIDs and terminal priority indicators; obtaining (504, 505) a first SPID corresponding to a first terminal; wherein the obtaining the first SPID comprises receiving the first SPID sent by a mobility management entity, MME, wherein the first SPID is sent by a home subscriber server, HSS, to the MME; learning an existing policy according to the operator-defined SPID, wherein the operator-defined SPID is obtained by mapping the first SPID to the operator-defined SPID in the second mapping table; and obtaining (506, 507) according to the service policy information and the first SPID, terminal information of the first terminal, and wherein the base station obtains the terminal information of the first terminal by mapping the first SPID to a terminal priority indicator and mapping the terminal priority indicator to terminal information in the mapping tables; wherein the terminal information comprises one of or a combination of the following information: a terminal supplier, a terminal model, and a terminal operating system.
