Problems solved by technology

According to network planning and coverage, there may be multiple base stations in the TAI list. If the target UE to be paged is under the last base station in the TAI list, the paging time will be longer and the system load will be heavier, which will affect to the processing speed of the entire system

Embodiment Construction

[0025] In the embodiment of the present invention, the MME pre-stores the base station to which the UE performing the setting operation within the first setting time belongs, and the probability of paging the target UE in the pre-stored base station is relatively high. When the UE triggers the condition, it will send the paging message to the base station stored in itself firstly, so as to speed up the paging speed.

[0026] The method embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 2 It is a schematic flow diagram of a specific embodiment of the method of the present invention.

[0028] see figure 2 As shown, a method for paging a UE provided in an embodiment of the present invention includes the following steps:

[0029] Step 201: The MME determines that the trigger condition for paging the UE is met.

[0030] Step 202: The MME sends a paging message to the stored base station to whic...

Abstract

The invention discloses a method and device for paging user equipment (UE). The method comprises the following steps that: A, a mobile management entity (MME) determines that trigger conditions for paging UE are reached; B, the MME transmits a paging message to a base station stored by the MME, wherein UE which performs set operation within a first set time belongs to the base station, and the paging message comprises the identity information of paged target UE; C, if the MME does not receive a service request message of the target UE within a second set time after sending the paging message, the MME sends a paging message to a base station in a cellular global identity; and D, if the MME does not receive the service request message of the target UE within a third set time after sending the paging message to the base station in the cellular global identity, the MME sends the paging message to a base station in tracking area codes. Therefore, by using the invention, the paging speed can be accelerated, and the load of a system in the paging course can be effectively reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for paging a user terminal. Background technique [0002] In the Evolved Packet System (EPS), after the user equipment (UE) attaches successfully, in order to save resources on the network side, when the UE and the network side do not need to transmit data on the user plane, the mobility on the network side is released. A radio resource control (Radio Resource Control, RRC) connection and an S1 connection between a permanent management entity (Mobility Management Entity, MME) and a UE. If the downlink data transmission or the signaling process triggered by the network side requires the MME to connect with the UE in the idle state, the MME on the network side will page the UE and re-establish the RRC connection and S1 connection with the UE. [0003] figure 1 For a schematic flowchart of a method for MME paging a UE in the prior art, see figure 1 As show...
