Embodiment 1

[0066] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, such as Figure 4 As shown, the computer terminal may include one or more (only one is shown in the figure) processor 401 (the processor 401 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), for storing Data storage 403, and transmission means 405 for communication functions. Those of ordinary skill in the art can understand that, Figure 4 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device.

[0067] The memory 403 can be used to store software programs and modules of application software, such as program instructions / modules corresponding to the device control method in the embodiment of the present invention, an...

Embodiment 2

[0195] The embodiment of the present invention also provides a cross-system switching device. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and what has been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0196] Figure 13 is a schematic diagram of an optional cross-system switching device according to an embodiment of the present invention. Such as Figure 13 As shown, the apparatus may include: an acquiring unit 131 and a first sending unit 132 .

[0197] The learning unit 131 is configured to learn that a cross-system handover of the user equipment UE occurs, wherein the cross-system handover refers to the ...

Embodiment 3

[0214] The embodiment of the invention also provides a storage medium. Optionally, in this embodiment, the above-mentioned storage medium may be configured to store program codes for performing the following steps:

[0215] S11. It is learned that the user equipment UE has a cross-system handover, where the cross-system handover refers to the handover of the UE from the fifth-generation mobile communication technology 5G system to the fourth-generation mobile communication technology 4G system;

[0216] S12. During the handover process of the UE from the 5G system to the 4G system, send the pre-saved target bearer information of the UE to the mobile management node function MME module, wherein the MME module located in the 4G system is used to follow the received target bearer information. The information reserves resources for the UE on the radio side.

[0217] Optionally, the storage medium is also configured to store program codes for performing the following steps:

Abstract

The invention provides a cross-system switching method and a cross-system switching device, wherein the method comprises the following steps: a first access and mobility control function AMF module learns that UE perform cross-system switching, wherein cross-system switching refers to that the UE switch from a 5G system to a 4G system, and the first AMF module is located in the 5G system; in the process where the UE switch from the 5G system to the 4G system, the first AMF module sends prestored target bearer information of the UE to a mobile management node function MME module, the MME modulein the 4G system is used for reserving resource for the UE at a wireless side according to the received target bearer information. With the method and the device provided by the invention, a technical problem that the wireless side cannot reserve resource for the UE since the AMF cannot generate session information when cross-system switching is executed in related technologies is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cross-system switching method and device. Background technique [0002] 3GPP (3rd Generation Partnership Project) started to formulate the fourth generation (or called LTE, Long Term Evolution, long-term evolution) mobile communication system from R8. Its network architecture is as figure 1 As shown, the functions of each network element in the architecture are as follows: [0003] Terminal (UE, User Equipment): It mainly accesses the 4G network and obtains services through the wireless air interface. The terminal exchanges information with the eNB base station through the air interface, and through the non-access stratum signaling NAS (non-Access Stratum) and the mobility management of the core network Entity interaction information. [0004] Base station (RAN, Radio Access Network, eNB): responsible for air interface resource scheduling and air interface connection manage...
