Embodiment 1

[0039] The method for controlling Internet access time in this embodiment, such as figure 1 shown, including the following steps:

[0040] Step S101: After establishing an uplink with the terminal device, a downlink with the terminal device may be established in advance;

[0041] In this step, after the network side establishes the uplink with the terminal device, it should be understood that the establishment of the uplink here includes the uplink establishment of one-step packet uplink access and / or the uplink establishment of two-step packet uplink access . No matter which way the uplink is established, after the uplink is established, the downlink of the terminal device can be pre-established.

[0042] Step S102: When receiving the downlink data instruction issued by the core network, perform downlink data access and transmission through the downlink.

[0043] In this step, when the network side receives the downlink data instruction issued by the core network, that is,...

Embodiment 2

[0048] In order to describe the content of the present invention in more detail, this embodiment will be described in detail in conjunction with the establishment process of the specific uplink. It is worth noting that this example mainly focuses on the establishment of the downlink. It mainly refers to the pre-established downlink in the first embodiment, and the downlink data access and transmission through the downlink are the same as the above-mentioned embodiment. Below, combine figure 2 with image 3 To elaborate:

[0049] figure 2 It is a flow chart of downlink data access and transmission when a packet is accessed in one step uplink, specifically including steps:

[0050] Step S201: the user terminal device initiates a CHANNEL REQUEST message (packet channel request);

[0051] Step S202: the network side sends a PACKET UPLINK ASSIGNMENT message (packet uplink assignment) to the user terminal equipment;

[0052] In this step, after receiving the message, the netw...

Embodiment 3

[0069] The downlink data access and transmission device 401 of this embodiment includes an establishment module 4011 and a transmission module 4012: the establishment module 4011 is used to establish a downlink with the terminal equipment in advance after establishing an uplink with the terminal equipment; the transmission module 4012 is configured to perform downlink data access and transmission through the downlink when receiving the downlink data access and transmission instruction issued by the core network.

[0070] Specifically, the establishment module 4011 is also used to: directly establish a downlink with the terminal device; or determine whether the ratio of the current number of users and the maximum number of accessible users is less than a preset ratio, and if so, establish a downlink with the terminal device Presetting the downlink; or judging whether the data currently transmitted by the uplink is transmitted through a specific port, and if so, establishing a pr...

Abstract

The invention provides a downlink data access and transmission method and apparatus, being applied to the communication field. The downlink data access and transmission method comprises the steps: after establishing an uplink with terminal equipment, pre-establishing a downlink with the terminal equipment; and when a downlink data access and transmission command issued from a core network is received, performing downlink data access and transmission through the downlink. Compared with the prior art, for the downlink data access and transmission method, as the downlink is pre-established before the core network issues the downlink data access and transmission command, the established downlink can be directly used to perform downlink data access and transmission when the downlink data access and transmission command is received, and establishment of the downlink is no longer performed after the core network issues the downlink data access and transmission command. Therefore, the time of the series of flows, such as resource distribution, designation and negotiation is saved, so that the time for downlink data access and transmission is saved; unnecessary delay is avoided; the network performance is improved; and then the user experience degree is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for accessing and transmitting downlink data. Background technique [0002] GPRS / EGPRS is a mobile packet data service developed on the basis of the original Global System for Mobile Communication (GSM) by introducing packet switching functional entities to support data transmission in packet mode. With the rapid growth of users' demand for mobile Internet, while it provides traffic services with the maximum capacity, it also puts forward higher requirements for network delay. [0003] According to the GPRS / EGPRS wireless access technology protocol, the process of mobile user terminal equipment accessing the wireless network in the packet service initiated by it can be divided into one phase access (packet uplink one-step access) and two phase access (packet uplink two-step access) access). From the access process described in the protocol, it can be seen t...
