Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a packet switched link.

In the LTE network, when a Mobile terminal resides in the LTE network, a radio protocol stack of the Mobile terminal automatically establishes a default packet switched link for the Mobile terminal, so as to keep the Mobile terminal permanently online, and during a subsequent use process of the Mobile terminal, it is ensured that at least one packet switched link is in an online state, so as to ensure that the Mobile terminal does not fall back from the LTE network to 2/3G networks such as GSM (Global System for Mobile Communication).
At present, a mobile terminal adopting the android system needs to be a packet switched link which is requested to be activated by the android system and is used by the mobile terminal of the android system, and thus, the mobile terminal of the android system cannot use the default packet switched link which is automatically established for the mobile terminal by using the wireless protocol stack. For this situation, there are two conventional solutions in the industry today, one of which is: firstly, a mobile terminal of an android system is registered to a GSM network, then the android system initiates a packet switching link activation request under the GSM network, when a packet switching link under the GSM network is established, the packet switching link is reselected to an LTE network, and as the packet switching link (namely the packet switching link under the GSM network) is already existed at the moment, a wireless protocol stack of the LTE network cannot additionally establish a default packet switching link, and the other scheme is as follows: the mobile terminal does not use a default packet switching link automatically established by a wireless protocol stack of an LTE network, but is idle in a command state all the time, and when the android system initiates a request for activating the packet switching link, a path of packet switching link is additionally established.
However, in the process of implementing the present invention, the inventor of the present application finds that, when an LTE network is reselected from a GSM network, a packet switched link established in the GSM network inevitably needs to go through a process of reconfiguring parameters in order to meet a requirement of high LTE rate, which may greatly delay a time for a user to use the LTE network, and may result in a poor experience for a user who desires to rapidly reside in the LTE network.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a configuration method of a packet switching link. The specific flow is shown in figure 1.
In step 101, an initial packet switched link is established.
Specifically, after detecting that the terminal device is registered in the LTE network, the wireless protocol stack of the terminal device establishes an initial packet switched link according to a preset internet protocol IP address type, that is, the terminal device directly resides in the LTE network, and the wireless protocol stack of the terminal device automatically establishes an initial packet switched link of a corresponding IP address type for the terminal device, where the preset internet protocol IP address type at least includes one of: IPv4, IPv6, IPv4v6, generally, the IP address type will default to IPv4v6, but the user can modify it as required. The terminal equipment directly resides in the LTE network, and the waiting process of reselecting the LTE network from 2/3G networks such as GSM and the like is effectively avoided.
In step 102, it is detected whether the access point names are the same, if the access point names are the same, step 103 is executed, otherwise step 105 is executed.
Specifically, the RIL (Radio Interface Layer) of the terminal device queries the access point name APN of the current initial packet switched link from the Radio protocol stack, detects whether the APN in the request message for establishing the target packet switched link by the terminal device is the same as the APN of the initial packet switched link, and simultaneously saves the detection result, if the APN is the same, the service type requested by the terminal device is the same as the service type of the initial packet switched link, step 103 is executed, if the IP address types are the same, and if the APNs are not the same, step 105 is executed, and the target packet switched link is newly established. By detecting the APN, whether the service type of the initial packet switching link is the same as the service type requested by the terminal equipment can be effectively detected, and the initial packet switching link is ensured to be multiplexed by the target packet switching link of the same service type.
In step 103, it is detected whether the IP address types are the same, if the IP address types are the same, step 104 is executed, otherwise step 105 is executed.
Specifically, the RIL of the terminal device queries the radio protocol stack for the IP address type of the current initial packet switched link, detects whether the IP address type in the request message for establishing the target packet switched link of the terminal device is matched with the IP address type of the initial packet switched link, and meanwhile, stores the detection result, if the IP address type of the request message is matched with the IP address type of the initial packet switched link, step 104 is executed to multiplex the initial packet switched link into the target packet switched link, otherwise, step 105 is executed to newly establish the target packet switched link. Further, the details of whether the IP address types are matched are shown in table 1 below:
TABLE 1
In step 104, the initial packet-switched link is multiplexed into the target packet-switched link.
Specifically, the initial packet switched link is switched to a data state and used as a target packet switched link to transmit data such as IP. The wireless protocol stack ensures that at least one path of initial packet switching link is fully multiplexed on the premise of maintaining the resident LTE network, so that the idle of the initial packet switching link activated by the wireless protocol stack is avoided, and the utilization rate of wireless network resources is effectively improved.
In step 105, the target packet-switched link is newly established.
Specifically, when the initial packet switched link cannot be multiplexed, it is necessary to newly establish a target packet switched link for the terminal device according to a request message for establishing the target packet switched link for the terminal device, so as to perform transmission of data such as IP.
In step 106, the initial packet-switched link is closed.
Specifically, when a target packet switched link is newly established for the terminal device, the initial packet switched link is in an idle state and needs to be closed, so that the utilization rate of wireless network resources is improved, and the power consumption of the terminal is reduced.
Compared with the prior art, the implementation mode of the invention has the advantages that the terminal equipment directly resides in the LTE network, the wireless protocol stack of the terminal equipment automatically establishes the initial packet switched link of the corresponding IP address type for the terminal equipment, the waiting process that the terminal equipment is firstly registered to the GSM network and then reselects from the 2/3G network such as the GSM network to the LTE network is effectively avoided, when the terminal equipment receives the request message for establishing the target packet switched link, whether the service type is the same is detected through the APN of the request message and the APN of the initial packet switched link, thereby ensuring that the initial packet switched link can be multiplexed by the target packet switched link of the same service type, when the APN is the same, whether the IP address type of the request message is the same as the IP address type of the initial packet switched link is further detected, thereby quickly and accurately judging whether the initial packet switched link can be multiplexed, when the initial packet switching link is multiplexed, the initial packet switching link is converted into a data state and serves as a target packet switching link, so that the initial packet switching link activated by a wireless protocol stack is fully multiplexed, the idle state of the initial packet switching link is avoided, the utilization rate of wireless network resources is effectively improved, when the initial packet switching link cannot be multiplexed, the target packet switching link is newly established for the terminal equipment, the initial packet switching link is closed, the initial packet switching link is effectively prevented from being in an idle state all the time, and the power consumption of the terminal is reduced.
A second embodiment of the present invention relates to a method for configuring a packet-switched link. The second embodiment is further improved on the basis of the first embodiment, and the main improvement is that: in the second embodiment of the present invention, the method includes not only the process of establishing the target packet-switched link, but also the process of closing the target packet-switched link, as shown in fig. 2.
In step 201, an initial packet switched link is established.
In step 202, it is detected whether the access point names are the same, if the access point names are the same, step 203 is executed, otherwise, the process is ended.
In step 203, it is detected whether the IP address types are the same, if the IP address types are the same, step 204 is executed, otherwise step 205 is executed.
In step 204, the initial packet-switched link is multiplexed into the target packet-switched link.
In step 205, the target packet-switched link is newly established.
In step 206, the initial packet-switched link is closed.
In step 207 it is detected whether a request message to close the target packet switched link is received, if so, step 208 is performed, otherwise it is ended.
Specifically, due to the feature that the LTE network is permanently online, the situation that the terminal device initiates a request message for closing the packet switched link needs to be considered, that is, the terminal device detects whether the request message for closing the target packet switched link is received in real time, if the request message for closing the target packet switched link is received, step 208 is executed, otherwise, the process is ended.
In step 208 it is detected whether the initial packet switched link is multiplexed as a target packet switched link, if the initial packet switched link is multiplexed as a target packet switched link, step 209 is performed, otherwise step 210 is performed.
Specifically, since only one packet switched link exists when the initial packet switched link is multiplexed as the target packet switched link, the target packet switched link cannot be directly closed at this time, and if the target packet switched link is directly closed, the network falls back to the 2/3G network such as GSM because no packet switched link remains, so that it is necessary to further detect whether the initial packet switched link is multiplexed as the target packet switched link, if the initial packet switched link is multiplexed as the target packet switched link, step 209 is executed to change the target packet switched link to the command state, otherwise step 210 is executed to close the target packet switched link.
Further, since the RIL of the terminal device stores the detection result of whether the APN and the IP address types of the target packet switched link and the initial packet switched link are the same in the process of establishing the target packet switched link, it can be directly determined whether the initial packet switched link is multiplexed as the target packet switched link according to the detection result stored in the RIL.
In step 209, the target packet-switched link is transferred to the command state.
Specifically, when the original packet-switched link is multiplexed into the target packet-switched link, the target packet-switched link is switched to a command state to stop data transmission but keep the packet-switched link online.
In step 210, the target packet-switched link is closed.
Specifically, when the original packet-switched link is not multiplexed as the destination packet-switched link, the packet-switched link specified in the request message for closing the destination packet-switched link is directly closed.
In this embodiment, a related process of closing the target packet switched link is provided, and a specific process of closing the target packet switched link when the initial packet switched link is multiplexed into the target packet switched link is specifically provided, so that at least one path of initial packet switched link is ensured to maintain the resident LTE network.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the steps contain the same logical relationship, which is within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
