[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a block diagram of a communication system according to a first embodiment of the present invention. The communication system 1 disclosed in the present embodiment includes: a device 11 and a communication network 12. The communication network 12 includes a first communication network 121 and a second communication network 122; the device 11 is a multimode device, and the device 11 is capable of accessing the first communication network 121 via a first radio access technology or the second communication network 122 via a second radio access technology. The device 11 may be a mobile terminal with a processor, or may be a processor.
The device 11 includes an Application Processor (AP) 111 and a Modem 112. When the device 11 is configured to establish a data connection using only the first radio access technology, the application processor 111 determines whether the radio access technology currently used by the device 11 is the first radio access technology; if the radio access technology currently used by the device 11 is not the first radio access technology, the application processor 111 sends a request for releasing the data connection to the modem 112, and the modem 112 releases the data connection connected to the device 11 according to the request for releasing the data connection.
The application processor 111 includes an application framework (english: application framework) 113 and a Radio Interface Layer (RIL) 114, and the application framework 113 is connected to the modem 112 through the Radio interface layer 114. In particular, the application framework 113 determines that the device 11 is configured to establish a data connection using only the first radio access technology, and preferably the user configures the device 11 to establish a data connection using only the first radio access technology. When the device 11 is configured to establish a data connection using only the first radio access technology, the application framework 113 determines whether the radio access technology currently used by the device 11 is the first radio access technology; if the radio access technology currently used by the device 11 is not the first radio access technology, the application framework 113 sends a request for releasing the data connection to the radio interface layer 114, the radio interface layer 114 sends the request for releasing the data connection to the modem 112, and the modem 112 releases the data connection established by the device 11 according to the request for releasing the data connection.
Optionally, after releasing the data connection established by the device 11, the modem 112 sends a data connection release success to the radio interface layer 114, and the radio interface layer 114 sends the data connection success to the application framework 113.
Before the device 11 is configured to establish a data connection using only the first radio access technology, the device 11 accesses the second communication network 122 through the second radio access technology. Specifically, the application framework 113 sends a request for establishing a data connection with the second communication network 122 to the modem 112 through the wireless interface layer 114, and the modem 112 accesses the second communication network 122 through the second radio access technology according to the request for establishing a data connection with the second communication network 122, so as to establish a data connection with the second communication network 122. Taking the example that the device 11 adopts the android system, the modem 112 sends an Activate packet data protocol Context Request (english: Activate PDP Context Request) to the second communication network 122, and then receives an Activate packet data protocol Context accept (english: Activate PDP Context accept) from the second communication network 122, so that the device 11 establishes data connection with the second communication network 122.
In other embodiments, a person skilled in the art may also determine that the device 11 has only a service subscription of the first communication network 121 or that the device 11 does not reach the subscription quota, through the application processor 111, and the application processor 111 determines that the device 11 is to establish the data connection only by using the first radio access technology. Namely: if the application processor 111 determines that the device 11 has only a service subscription of the first communication network 121 or the device 11 does not reach the subscription quota, the application processor 111 determines whether the radio access technology currently adopted by the device 11 is the first radio access technology; if the radio access technology currently used by the device 11 is not the first radio access technology, the application processor 111 sends a request for releasing the data connection to the modem 112, and the modem 112 releases the data connection established by the device 11 according to the request for releasing the data connection. Wherein the quota under which the device 11 has not reached the subscription is a quota under which the device 11 has not reached the subscription in the first communication network 121.
The application processor 111 further determines whether the radio access technology of the device 11 is changed to the first radio access technology, and if the radio access technology of the device 11 is changed to the first radio access technology, the application processor 111 sends a request for establishing a data connection to the modem 112, and the modem 112 establishes a data connection with the first communication network 121 using the first radio access technology according to the request for establishing a data connection. In particular, when the radio access technology of the device 11 changes to the first radio access technology, i.e. the device 11 reselects or switches to the first communication network 121. The modem 112 informs the application framework 113 via the radio interface layer 114 that the radio access technology of the device 11 is changed to the first radio access technology, the application framework 113 determines that the radio access technology of the device 11 is changed to the first radio access technology and sends a request to establish a data connection to the modem 112 via the radio interface layer 114, and the modem 112 establishes a data connection with the first communication network 121 using the first radio access technology according to the request to establish a data connection.
Notably, the configuration of the device 11 to establish a data connection using only the first radio access technology may be achieved by at least one of:
the user manually configures the device 11 to establish data connection only by using the first radio access technology;
alternatively, device 11 automatically configures device 11 to establish a data connection using only the first radio access technology based on messages (or signaling) received from communication network 12;
alternatively, the device 11 sets up the data connection with the first radio access technology only by the device 11 before shipment.
Preferably, the first radio access technology is a radio access technology in LTE (Long term evolution, abbreviated as LTE), the first communication network 121 is a communication network using 4G (4 th Generation), the second radio access technology is a radio access technology in 2G (2 nd Generation) or a radio access technology in 3G (3 rd Generation), and the second communication network 122 is a communication network using 2G or a communication network using 3G.
When the device 11 is configured to establish a data connection only using the first radio access technology, the application processor 111 determines whether the radio access technology currently used by the device 11 is the first radio access technology; if the radio access technology currently employed by device 11 is not the first radio access technology, application processor 111 sends a request to release the data connection to modem 112, modem 112 releases the data connection that device 11 has established based on the request to release the data connection, application processor 111 also determines whether the radio access technology of device 11 has changed to the first radio access technology, if the radio access technology of device 11 has changed to the first radio access technology, the application processor 111 sends a request for establishing a data connection to the modem 112, and the modem 112 establishes a data connection with the first communication network 121 using the first radio access technology according to the request for establishing a data connection, so that the device 11 can establish a data connection with the first communication network 121 (the communication network using 4G) using only the first radio access technology (the radio access technology in 4G).
The present invention also provides a communication system of a second embodiment, which is described on the basis of the communication system 1 disclosed in the first embodiment. The communication system disclosed in this embodiment further includes: before the device 11 is configured to establish the data connection using only the first radio access technology, the application processor 111 further performs at least one of the following detections:
the application processor 111 determines whether the device 11 has changed to establish a data connection using only the first radio access technology, i.e.: the application framework 113 determines whether the device 11 has changed to establish a data connection using only the first radio access technology;
alternatively, the application processor 111 determines whether the device 11 is to turn on data traffic, i.e.: the application framework 113 determines whether the device 11 is open for data traffic;
alternatively, the application processor 111 determines whether the device 11 is successfully registered via the first radio access technology, i.e.: the application framework 113 determines whether the device 11 is successfully registered via the first wireless access technology;
if the result of the detection by the application processor 111 is yes, the device 11 is configured to establish a data connection using only the first radio access technology.
The modem 112 releases the established data connection of the device 11 according to the request for releasing the data connection, where the established data connection of the device 11 is a data connection that is not used for the multimedia message service, that is, the access point name corresponding to the established data connection of the device 11 is the access point name corresponding to the data connection that is not used for the multimedia message service. Therefore, the application framework 113 does not request the modem 112 to release the data connection not used for the multimedia message service, but only requests the modem 112 to release the data connection other than the data connection used for the multimedia message service.
The modem 112 releasing the data connection that has been established by the device 11 according to the request for releasing the data connection includes: the modem 112 sends a Request for deactivating a packet data protocol Context (deactivating PDP Context Request) to the second communication network 122 and receives a deactivating PDP Context accept (deactivating PDP Context accept) from the second communication network 122, thereby releasing the data connection established with the second communication network 122.
The device 11 further comprises a timer 13, the timer 13 being connected to an application framework 113 of the application processor 111, as shown in fig. 2. If the radio access technology currently employed by the device 11 changes to the first radio access technology within the preset duration of the timer 13, the application processor 111 sends a request to establish a data connection to the modem 112. Specifically, the application framework 113 determines that the radio access technology of the device 11 is changed to the first radio access technology within a preset time period, and the application framework 113 sends a request for establishing a data connection to the modem 112; the application framework 113 determines that the radio access technology of the device 11 has not changed to the first radio access technology within the preset time period, and ends.
The establishing, by the modem 112, the data connection with the first communication network 121 using the first radio access technology according to the data connection establishing request includes:
the modem 112 sends a packet data network connection Request (PDN ConnectivityRequest) to the first communication network 121, and then receives an Activate Default enhanced packet switched bearer Context Request (active Default EPS bearer Context Request) from the first communication network 121, and the modem 112 replies an Activate Default enhanced packet switched bearer Context Accept (PDN bearer Context Accept) to the first communication network 121, and then the modem 112 establishes a data connection with the first communication network 121.
Alternatively, the modem 112 sends a Bearer resource allocation Request (english: Bearer resource allocation Request) to the first communication network 121, and then receives an Activate Dedicated enhanced packet switched Bearer Context Request (english: Activate Dedicated enhanced packet switched Bearer Context Request) from the first communication network 121, and the modem 112 replies an Activate Dedicated enhanced packet switched Bearer Context Accept (english: Activate Dedicated EPS Bearer Context Accept) to the first communication network 121, and then the modem 112 establishes a data connection with the first communication network 121.
Alternatively, the modem 112 informs the radio interface layer 114 that the data connection is successfully established, and the radio interface layer 114 informs the application framework 113 that the data connection is successfully established.
The following describes in detail the reselection or handover of the device 11 from the communication network employing 2G or the communication network employing 3G (the second communication network 122) to the communication network employing 4G (the first communication network 121).
As shown in fig. 3, the device 11 is currently registered in the communication network using 2G or the communication network using 3G and establishes a packet data connection in the communication network using 2G or the communication network using 3G, wherein the modem 112 initiates a packet data connection establishment request to the communication network using 2G or the communication network using 3G according to the data connection establishment request sent by the application processor 111, and the device 11 establishes a packet data connection in the communication network using 2G or the communication network using 3G. Specifically, the application framework 113 requests the wireless interface layer 114 to establish a data connection, the wireless interface layer 114 sends a Request for establishing a data connection to the modem 112, the modem 112 establishes a packet data connection in the 2G communication network or the 3G communication network according to the Request for establishing a data connection, that is, the modem 112 sends an activated determined EPS Bearer Context Request to the 2G communication network or the 3G communication network, and then receives an activated determined epsbeacon Context Request from the second communication network 122.
When the device 11 is configured to establish a data connection using only the radio access technology in 4G, the user setting device 11 turns on the feature of using only the radio access technology in 4G. If the application framework 113 checks that the device 11 is configured to establish a data connection using only the radio access technology in 4G and that the radio access technology currently used by the device 11 is not the radio access technology in 4G, the application framework 113 sends a release data connection request to the radio interface layer 114.
Furthermore, the application framework 113 may also be configured to establish the data connection only by using the radio access technology in 4G according to the subscription data, that is, if the application framework 113 determines that the device 11 is only subscribed to the service of the communication network using 4G, or if the subscription of the device 11 in the communication network using 4G does not reach the quota, the application framework 113 further determines whether the radio access technology currently used by the device 11 is the radio access technology in 4G.
Before the device 11 is configured to establish a data connection using only the radio access technology in 4G, the application framework 113 may also perform at least one of the following checks:
1) the application framework 113 determines whether the user configuration device 11 has changed to establish a data connection using only the radio access technology in 4G;
2) the application framework 113 determines whether the device 11 is open for data traffic;
3) the application framework 113 determines whether the device 11 successfully registers via LTE wireless access technology;
if the application framework 113 performs the above detection, the device 11 is configured to establish the data connection only using the radio access technology in 4G.
The application framework 113 sends a request to release the data connection to the radio interface layer 114, the radio interface layer 114 sends the request to release the data connection to the modem 112, and the modem 112 releases the established data connection according to the request to release the data connection. The data connection established by the device 11 is a data connection that is not used for the multimedia message service, that is, the access point name corresponding to the data connection established by the device is an access point name corresponding to the data connection that is not used for the multimedia message service. Therefore, the application framework 113 does not request the modem 112 to release the data connection of the multimedia message service, but only requests the modem 112 to release other data connections except the data connection of the multimedia message service.
Wherein the modem 112 releases the already established data connection according to the release data connection request. That is, the modem 112 sends a deactivating PDP Context Request to the 2G communication network or the 3G communication network, and receives deactivating PDP Context from the 2G communication network or the 3G communication network, thereby releasing the data connection established between the device 11 and the 2G communication network or the 3G communication network. The modem 112 releases the data connection which has been established with the communication network using 2G or the communication network using 3G, but does not include the data connection of the multimedia message service.
Alternatively, the modem 112 notifies the radio interface layer 114 that the data connection of the 2G communication network or the 3G communication network has been successfully released, and the radio interface layer 114 notifies the application framework 113 that the data connection of the 2G communication network or the 3G communication network has been successfully released, that is, the modem 112 sends the data connection release success to the application framework 113 through the radio interface layer 114.
The modem 112 reselects or switches from the communication network employing 2G or the communication network employing 3G to the communication network employing 4G, i.e., the radio access technology of the device 11 changes to the radio access technology in 4G.
The modem 112 notifies the application framework 113 through the radio interface layer 114 that the radio access technology change of the device 11 has occurred, that is, the radio access technology of the device 11 is changed to the radio access technology in 4G.
The application framework 113 sends a request to establish a data connection to the modem 112 through the radio interface layer 114. Specifically, the method comprises the following steps:
the application framework 113 determines whether the radio access technology currently employed by the device 11 is that in 4G, and if so, the application framework 113 sends a request to establish a data connection to the modem 112 through the radio interface layer 114.
Alternatively, the application framework 113 makes the following determinations: 1) the device 11 is configured to employ only the radio access technology in 4G; 2) the user sets the feature that the opening device 11 only adopts the wireless access technology in 4G; 3) the radio access technology currently employed by the device 11 is not that in 4G; 4) determining that the current data service of the device 11 is not a multimedia message service; if the above conditions are satisfied, the application framework 113 does not send a request for establishing data connection; otherwise, the application framework 113 sends a request to establish a data connection to the modem 112 through the radio interface layer 114.
Alternatively, the application framework 113 makes the following determinations: 1) the device 11 is configured to employ only the radio access technology in 4G; 2) the user is configured to turn on the device 11 to employ only the features of the radio access technology in 4G; 3) the currently adopted wireless access technology of the device 11 is the wireless access technology in 4G, or the current data service of the device 11 is determined to be a multimedia message service; if the above condition is satisfied, the application framework 113 sends a request for establishing data connection to the modem 112 through the radio interface layer 114; otherwise, the application framework 113 does not send a request to establish a data connection.
The modem 112 initiates a data connection establishment request to the communication network employing 4G, thereby establishing a data connection employing 4G. Specifically, the modem 112 sends a packet data network connection Request to the 4G-based communication network, receives an activatedefaults EPS Bearer Context Request from the 4G-based communication network, and the modem 112 replies an Activate defaults epsiperer Context Accept to the 4G-based communication network, so that the modem 112 establishes a 4G data connection with the 4G-based communication network.
Or, the modem 112 sends a bearer resource allocation Request to the 4G-based communication network, then receives an active specified epsbsearred Context Request from the 4G-based communication network, the modem 112 replies an active specified EPS bearer Context Accept to the 4G-based communication network, and the modem 112 establishes a 4G data connection with the 4G-based communication network.
