detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

First embodiment

As shown in FIG. 2, a first embodiment of the present disclosure provides a method for a terminal to access a network, which is applied to a target base station, where the method includes step S201 and step S202.

Step S201: Obtain context information when the terminal is in the connected state.

In the first embodiment of the present disclosure, the foregoing context information includes: terminal capability, bearer (Data Radio Bearer (DRB) configuration parameters, security parameters, protocol (IP) addresses and SGW port numbers interconnected between Mobile Terminal Entity (MME)/Serving Gateway (SGW) networks.

In the first embodiment of the present disclosure, there are two implementations of the above step S201. The first type is: obtaining the context information when the terminal saved by the network side device (for example, the source base station, the mobile terminal entity, and the like) is in the connected state; the second type is: acquiring the context information when the terminal saved by the terminal is in the connected state.

Step S202, according to the context information, activate the connection and bearer of the terminal in the idle state.

In the first embodiment of the present disclosure, the target base station acquires context information when the terminal is in the connected state from the terminal or the network side device, and activates the connection and bearer of the terminal in the idle state according to the context information, thereby solving the problem that the terminal is idle. The time that the state enters the connection state is long, and the low-latency requirement cannot be met, resulting in a poor user experience. The terminal can quickly enter the connection state from the idle state to transmit data, meet the low latency requirement of the service, and reduce the signaling overhead of the packet service. To enhance the user experience.

In the first embodiment of the present disclosure, when the target base station obtains the context information when the terminal is in the connected state by acquiring the context information of the terminal that is stored in the connected state, the specific base station acquires the context when the terminal is in the connected state. The step of the information includes: as shown in FIG. 3, the target base station first receives the terminal identifier sent by the terminal, where the terminal identifier is a identifier that uniquely identifies the terminal within a certain range (for example, a tracking list or a cell list, etc.), and the identifier In the terminal identifier, the source base station identifier is indirectly or directly included (ie, carried); and then, according to the source base station identifier, whether the source base station and the target base station are the same base station, and when the source base station and the target base station are the same base station, according to the terminal identifier, the target base station is used. The context information when the terminal is in the connected state is obtained, and when the source base station and the target base station are different base stations, the context information when the terminal is in the connected state is obtained from the source base station according to the terminal identifier and the source base station identifier.

The step of obtaining the context information when the terminal is in the connected state from the source base station according to the terminal identifier and the source base station identifier is specifically as follows: as shown in FIG. 3, the target base station sends the context information when the terminal is in the connected state. And the request carries the terminal identifier; and then receives the context information when the terminal sent by the source base station is in the connected state. It is to be noted that, in order to activate the connection and the bearer of the terminal in the idle state, the target base station obtains the path information when the terminal is in the connected state from the source base station, and then sends a path change request to the MME, so that the MME sends the bearer modification to the SGW. Request, and the SGW returns bearer modification to the MME after receiving the bearer modification request. The reply message causes the MME to return a path change confirmation message to the target base station (of course, the interaction between the target base station, the MME and the SGW is of the prior art, and therefore is not described here).

As shown in FIG. 4, after acquiring the context information of the terminal in the connected state, the target base station may also send the source base station IP address and the SGW port number to the SGW according to the SGW IP address in the context information, so that the SGW will use the SGW. The downlink between the source base station is changed to the downlink between the SGW and the target base station.

In the first embodiment of the present disclosure, when the target base station obtains the context information when the terminal is in the connected state by acquiring the context information of the terminal that the terminal is in the connected state, the specific base station obtains the connection state when the terminal is in the connected state. The step of the context information includes: as shown in FIG. 5, the target base station first receives the terminal identifier sent by the terminal, where the terminal identifier is a identifier that uniquely identifies the terminal within a certain range (for example, a tracking list or a cell list, etc.), and In the terminal identifier, the mobile management entity identifier is indirectly or directly included (ie, carried); and then, according to the mobility management entity identifier, a request for acquiring context information when the terminal is in the connected state is sent to the mobility management entity, where the request carries the terminal identifier; Context information when the terminal sent by the mobility management entity is in the connected state. It should be noted that, in order to activate the connection and bearer of the terminal in the idle state, after receiving the request for acquiring the context information of the terminal in the connected state, the mobility management entity sends a bearer modification request to the SGW, and the SGW receives the bearer. After the modification request, the message carrying the modification reply is returned to the MME (of course, the interaction between the MME and the SGW here belongs to the prior art, so it is not described here).

In the first embodiment of the present disclosure, when the target base station obtains the context information when the terminal is in the connected state by acquiring the context information of the terminal that is in the connected state, the specific base station obtains the context information when the terminal is in the connected state. The steps are as follows: as shown in FIG. 6, the terminal directly sends the context information to the target base station, and in order to activate the connection and bearer of the terminal in the idle state, the target base station receives the request for the context information when the terminal is in the connected state. The source base station IP address and the SGW port number are sent to the SGW according to the SGW IP address in the context information, so that the SGW changes the downlink between the SGW and the source base station to the downlink between the SGW and the target base station.

In the first embodiment of the present disclosure, the specific implementation manner of the foregoing step S202, whether the target base station is the context information when the terminal acquired from the network side device is in the connected state, or the context information obtained when the terminal is in the connected state. all the same. Specifically, as shown in FIG. 3, FIG. 4, and FIG. 5 and FIG. 6 , the foregoing step S202 includes: the target base station determines whether it can accept the bearer configuration of the terminal according to the bearer configuration parameter in the context information, and sends a wireless connection activation to the terminal when it can accept the bearer configuration of the terminal. The message activates the connection and bearer of the terminal, and if it cannot accept the bearer configuration of the terminal or the access control fails, sends a wireless connection reject message to the terminal, refusing to activate the connection and bearer of the terminal.

It should be noted that, in order to reduce the air interface message, whether the target base station is the context information when the terminal acquired from the network side device is in the connected state or the context information obtained when the terminal is in the connected state, the terminal needs to save the terminal in the terminal. The DRB configuration parameters and security parameters in the connected state are such that after receiving the wireless connection activation message sent by the target base station, the corresponding bearer configuration is directly transmitted and the data is transmitted. However, as shown in FIG. 3, FIG. 4 and FIG. 5, when the target base station is context information when the terminal obtained from the source base station or the mobility management entity is in the connected state, after the terminal can transmit data to the network side, the source base station When the mobility management entity does not delete the context information when the terminal that is saved in the connected state, the target base station needs to send a context release message to the source base station or the mobility management entity, and the context release message carries the terminal identifier, so that the source base station or the mobility management The entity deletes the context information when the terminal saved by itself is in the connected state.

It should be noted that, as shown in FIG. 3, if the target base station is context information when the terminal obtained from the source base station is in the connected state, the air interface has two messages (the transmission delay of each message is 1 millisecond), and the network side is at least There are 6 to 8 messages (each message has a transmission delay of 3 to 5 milliseconds), and the node processing delay is 2 milliseconds, so a total of 1*2+4*(6~8)+2*(8~10) is required. =42~54ms The terminal can access the network to transmit data. If the target base station and the source base station are the same base station, there are only two air interface messages, and only 1*2+2*2=6 milliseconds terminal can access the network to transmit data.

Similarly, as shown in FIG. 4, if the target base station is context information when the terminal obtained from the source base station is in the connected state, the air interface has two messages (each message has a transmission delay of 1 millisecond), and the network side has at least 2 Messages (each message has a transmission delay of 3 to 5 milliseconds), and the node processing delay is 2 milliseconds. Therefore, a total of 1*2+4*2+2*4=18 milliseconds is required for the terminal to access the network to transmit data. If the target base station and the source base station are the same base station, there are only two air interface messages, and only 1*2+2*2=6 milliseconds terminal can access the network to transmit data.

Similarly, as shown in FIG. 5, if the target base station is context information when the terminal obtained from the mobility management entity is in the connected state, the air interface has two messages (each message has a transmission delay of 1 millisecond). There are at least 2 messages on the network side (each message has a transmission delay of 3 to 5 milliseconds), and the node processing delay is 2 milliseconds. Therefore, a total of 1*2+4*2+2*4=18 milliseconds is required for the terminal to access the network. transfer data.

Similarly, as shown in FIG. 6, if the target base station is context information when the terminal obtained from the terminal is in the connected state, the air interface has 2 messages (each message transmission delay is 1 millisecond), and the node processing delay is 2 milliseconds. Therefore, a total of 1*3+2*3=9 milliseconds is required for the terminal to access the network to transmit data.

Therefore, the foregoing method enables the terminal to quickly transfer data from the idle state to the connected state, meets the requirement of low service delay, reduces the packet signaling service overhead, and improves the user experience.
