Communications method and apparatus
First Claim
1. A communications method by a mobility management entity in a communication network, the method comprising:
- acquiring, by the mobility management entity (MME), information of a user equipment device (UE);
determining, by the MME according to the information of the UE, that the UE is a power-saving UE;
upon determining that the UE is a power-saving UE, generating, by the MME, a first indication comprising an instruction to retain first data, wherein the first data is downlink data of the UE; and
sending, by the MME, the first indication to a serving gateway (SGW) to instruct the SGW to retain the first data.

Abstract
Embodiments of the present invention relate to the field of communications, and provide a communications method and apparatus, which can solve a problem in the prior art that, in order to save power, when a mobility management entity (MME) delays delivering a paging message or a UE uses a long discontinuous reception (DRX) period, an exception may occur in a serving gateway (SGW). The method includes: acquiring, by an MME, infatuation of a UE (S101); determining, by the MME according to the information, whether the UE satisfies a first preset condition (S102); if the UE satisfies the first preset condition, generating, by the MME, a first indication, where the first indication is used for instructing an SGW to retain first data or discard first data, and the first data is downlink data of the UE (S103); and sending, by the MME, the first indication to the SGW.

5. A mobility management entity (MME), comprising:
-
a processor, configured to; acquire information of a user equipment device (UE), determine, according to the information of the UE, that the UE is a power-saving UE, generate a first indication comprising an instruction to retain first data, wherein the first data is downlink data of the UE; a memory, configured to store the information of the UE acquired by the processor and the first indication generated by the processor; and a transmitter, configured to send the first indication stored in the memory and generated by the processor to a serving gateway (SGW) to instruct the SGW to retain the first data. - View Dependent Claims (6, 7)
