Abstract
A data communication method, a communication system, and related devices are configured to establish a transaction identifier (TI) in a user equipment (UE). The data communication method includes the following steps. A mobility management entity (MME) receives a request message and obtains ability information of the UE. If the UE has an ability to access a Universal Terrestrial Radio Access Network/GSM/EDGE Radio Access Network (UTRAN/GERAN), the MME generates the TI. A communication system and related devices are also provided. Thus, the TI is effectively established in the UE, so as to ensure normal processing of the UE.
Claims3
An apparatus for data communication, wherein the apparatus is comprised in a user equipment, and the apparatus comprises:
- a transmitter;
- a receiver;
- a processor configured to:
- send, via the transmitter, a request message to a mobility management entity (MME) of a long term evolution (LTE) network, wherein the request message comprises ability information of the user equipment indicating whether the user equipment has an ability to access one of a Universal Terrestrial Radio Access Network (UTRAN) and a GSM/EDGE Radio Access Network (GERAN);
- receive, via the receiver, a transaction identifier (TI), wherein the TI is generated based on the ability information of the user equipment by the MME and for a bearer identifier of the user equipment in the LTE network;
- communicate, via the receiver and the transmitter, with the LTE network to leave the LTE network;
- and
- perform an access procedure to access, via the receiver and the transmitter, the one of the UTRAN and the GERAN by using the TI.
A non-transitory computer-readable medium storing a set of instructions for data communication, the set of instructions are used to direct a processor of a user equipment to perform acts of:
- send, via a transmitter of the user equipment, a request message to a mobility management entity (MME) of a long term evolution (LTE) network, wherein the request message comprises ability information of a user equipment indicating whether the user equipment has an ability to access one of a Universal Terrestrial Radio Access Network (UTRAN) and a GSM/EDGE Radio Access Network (GERAN);
- receive, via a receiver of the user equipment, a transaction identifier (TI), wherein the TI is generated based on the ability information of the user equipment by the MME and for a bearer identifier of the user equipment in the LTE network;
- communicate, via the receiver and the transmitter, with the LTE network to leave the LTE network;
- and
- perform an access procedure to access, via the receiver and the transmitter, the one of the UTRAN and the GERAN by using the TI.
