Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

first embodiment

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

Step S201, acquiring context information when the terminal is in a connected state.

In the first embodiment of the present invention, the above context information includes: terminal capability, bearer (DRB) configuration parameters, security parameters, protocol (IP) for interconnection between mobile terminal entity (MME)/serving gateway (SGW) networks address and SGW port number, etc.

In the first embodiment of the present invention, there are two ways to implement the above step S201. The first one is: obtain the context information when the terminal is in the connected state saved by the network side equipment (such as the source base station, the mobile terminal entity, etc.); the second one is: obtain the context information when the terminal is in the connected state saved by the terminal.

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 invention, the target base station obtains the context information when the terminal is in the connected state from the terminal or network side equipment, and activates the connection and bearer of the terminal in the idle state according to the context information, which solves the problem that the terminal is in the idle state. It takes a long time for the terminal to enter the connected state, which cannot meet the low-latency requirements, resulting in poor user experience. It enables the terminal to quickly enter the connected state from the idle state to transmit data, meets the low-latency requirements of the business, and reduces the signaling overhead of small-packet services. , to enhance the effect of user experience.

In the first embodiment of the present invention, when the target base station obtains the context information when the terminal is in the connected state by obtaining the context information when the terminal is in the connected state saved by the source base station, it specifically obtains the context information when the terminal is in the connected state The step of information includes: as shown in Figure 3, the target base station will first receive the terminal identifier sent by the terminal, the terminal identifier is an identifier that uniquely characterizes the terminal within a certain range (such as a tracking list or a cell list, etc.), and the The terminal ID contains (i.e. carries) the source base station ID indirectly or directly; then, according to the source base station ID, it is judged whether the source base station and the target base station are the same base station; Find the context information when the terminal is in the connected state, and when the source base station and the target base station are different base stations, obtain the context information when the terminal is in the connected state from the source base station according to the terminal ID and the source base station ID.

Wherein, 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 is specifically as follows: As shown in Figure 3, the target base station will send the context information obtained when the terminal is in the connected state and the request carries the terminal identifier; and then receives the context information sent by the source base station when the terminal 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, the target base station will send a path change request to the MME after obtaining the context information of the terminal in the connected state from the source base station, so that the MME sends a bearer modification request to the SGW request, and the SGW will return a bearer modification reply message to the MME after receiving the bearer modification request, so that the MME returns a path change confirmation message to the target base station (of course, the interaction between the target base station, MME and SGW here belongs to the prior art, Therefore, it will not be described in detail here).

As shown in Figure 4, after the target base station obtains the context information when the terminal is in the connected state from the source base station, it can also send the source base station IP address and SGW port number to the SGW according to the SGW IP address in the context information, so that the SGW will send the SGW port number to the SGW The downlink with the source base station is changed to the downlink between the SGW and the target base station.

In the first embodiment of the present invention, when the target base station obtains the context information when the terminal is in the connected state by obtaining the context information when the terminal is in the connected state saved by the mobility management entity, it specifically obtains the context information when the terminal is in the connected state The steps of context information include: as shown in Figure 5, the target base station will first receive the terminal identifier sent by the terminal, the terminal identifier is an identifier that uniquely characterizes the terminal within a certain range (such as a tracking list or a cell list, etc.), and The terminal identification indirectly or directly contains (that is, carries) the mobile management entity identification; then according to the mobile management entity identification, sends to the mobile management entity a request for obtaining context information when the terminal is in a connected state, and the request carries the terminal identification; finally receives Context information sent by the mobility management entity when the terminal 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, the mobility management entity will send a bearer modification request to the SGW after receiving the request for obtaining the context information of the terminal in the connected state, and the SGW will After the modification request, a message carrying a modification reply will be returned to the MME (of course, the interaction between the MME and the SGW here belongs to the prior art, so it will not be described here).

In the first embodiment of the present invention, when the target base station obtains the context information when the terminal is in the connected state by obtaining the context information when the terminal is in the connected state saved by the terminal, it specifically obtains the context information when the terminal is in the connected state The steps are: as shown in Figure 6, the terminal will directly send 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 will receive the context information request when the terminal is in the connected state , will send the source base station IP address and SGW port number 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 invention, regardless of whether the target base station is the context information obtained from the network side device when the terminal is in the connected state or the context information obtained from the terminal when the terminal is in the connected state, the specific implementation of the above step S202 all the same. Specifically, as shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the above step S202 includes: the target base station will judge whether it can accept the bearer configuration of the terminal according to the bearer configuration parameters in the context information. When configuring the bearer configuration, send a wireless connection activation message to the terminal to activate the connection and bearer of the terminal, and if it cannot accept the bearer configuration of the terminal or the access control fails, it will send a wireless connection rejection message to the terminal to refuse to activate the connection of the terminal and bearer.

It should be noted that, in order to reduce air interface messages, regardless of whether the target base station obtains the context information when the terminal is in the connected state from the network side device or obtains the context information when the terminal is in the connected state from the terminal, the terminal needs to save the context information when the terminal is in the connected state. DRB configuration parameters and security parameters in the connected state, so that after receiving the wireless connection activation message sent by the target base station, the corresponding bearer configuration can be directly performed to transmit data. However, as shown in Figure 3, Figure 4 and Figure 5, when the target base station is the context information obtained from the source base station or the mobility management entity when the terminal is in the connected state, after the terminal can transmit data to the network side, when the source base station Or when the mobility management entity does not delete the context information saved by itself when the terminal is 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 entity The entity deletes the context information saved by itself when the terminal is in the connected state.

It should be noted that, as shown in Figure 3, if the target base station obtains context information from the source base station when the terminal is in the connected state, there are 2 messages on the air interface (the transmission delay of each message is 1 millisecond), and the network side at least There are 6 to 8 messages (the transmission delay of each message is 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 = 42-54 milliseconds, the terminal can access the network to transmit data. However, if the target base station and the source base station are the same base station, there are only 2 air interface messages, and it only takes 1*2+2*2=6 milliseconds for the terminal to access the network and transmit data.

Similarly, as shown in Figure 4, if the target base station obtains the context information when the terminal is in the connected state from the source base station, there are 2 messages on the air interface (the transmission delay of each message is 1 millisecond), and at least 2 messages on the network side message (transmission delay of each message is 3-5 milliseconds), node processing delay is 2 milliseconds, so a total of 1*2+4*2+2*4=18 milliseconds is required for the terminal to access the network to transmit data. However, if the target base station and the source base station are the same base station, there are only 2 air interface messages, and it only takes 1*2+2*2=6 milliseconds for the terminal to access the network and transmit data.

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

Similarly, as shown in Figure 6, if the target base station obtains context information from the terminal when the terminal is in the connected state, there are 2 messages on the air interface (the transmission delay of each message is 1 millisecond), and the node processing delay is 2 milliseconds , so it takes 1*3+2*3=9 milliseconds in total for the terminal to access the network and transmit data.

It can be seen that the above method enables the terminal to quickly transfer data from the idle state to the connected state, meet the low-latency requirements of the service, reduce the signaling overhead of the small-packet service, and improve user experience.
