The present invention discloses a method for obtaining an Internet protocol header replacement mapping and a network node, which belong to the field of communications technologies. The method includes: obtaining, by a network node, fixed IP header information which is bound to a UE, where the network node is an MME or an eNB or a PGW or an SGW; establishing an IP header replacement mapping according to the fixed IP header information, where the IP header replacement mapping is correspondence between the fixed IP header information and an index or a bearer; and performing data transmission with the UE according to the IP header replacement mapping. In the present invention, the network node establishes the IP header replacement mapping according to the obtained fixed IP header information which is bound to the UE, so, compared with an existing manner of configuring the mapping by an MTC server or manually, the method is more flexible and can reduce difficulty in configuring and maintaining the IP header replacement mapping; moreover, by expanding an entity for maintaining the IP header replacement mapping from an existing eNB to a network node such as an eNB, or an MME, or a PGW, or an SGW, flexibility in obtaining the IP header replacement mapping is further improved and the implementation manner becomes more universal. |
