Problems solved by technology

Since the DOWNLINK NAS TRANSPORT message does not carry UERadio Capability information in UP CIOT working mode; or the DOWNLINK NAS TRANSPORT message does not have UERadio Capability information in CP CIOT working mode, when the first DOWNLINK NAS TRANSPORT message received by E-UTRAN does not carry When receiving UE Radio Capability information, it does not indicate whether there is an INITIAL CONTEXT SETUPREQUEST message, so E-UTRAN cannot judge the process of triggering E-UTRAN to request the wireless capability information of the mobile terminal, or wait for the INITIAL CONTEXT SETUP REQUEST message and obtain wireless capability information from it
Therefore, due to the inability to obtain the wireless capability of the mobile terminal in real time, the utilization rate of wireless resources is low

[0110] The embodiment of the present invention is described in detail from the access network side.

[0111] For this step, reference may be made to the detailed description of step 101, which will not be repeated here.

[0112] Optionally, in another embodiment of the present invention, step 201 includes substeps 2011 to 2013:

[0113] Sub-step 2011, read the working mode identifier from the DOWNLINK NAS TRANSPORT message.

[0114] Specifically, according to the format of the DOWNLINK NAS TRANSPORT message, the working mode identifier is read ...

Embodiment 3

[0137] refer to image 3 , which shows a flow chart of the steps of Embodiment 3 of a method for acquiring a wireless capability according to the present invention, which may specifically include the following steps:

[0138] Step 301, determine the working mode of the mobile terminal according to the capability information reported by the mobile terminal and the capability information of the MME.

[0139] The embodiment of the present invention is described in detail from the MME network element side of the core network.

[0140] The terminal carries the network capability of the terminal in the attach request message, indicating the supported capability information: control plane optimization capability, user plane optimization capability, S1U data, EPS (Evolved Packet System, Evolved Packet System) attachment W / OPDN (Public Data Network, public data network) connection. EPS attached w / o PDN connection etc. Wherein, at the same time, the additional update type information...

Abstract

The embodiment of the invention provides a wireless capability obtaining method and device, and the method includes the steps: determining an operation mode of a mobile terminal according to a workingmode identifier in a DOWNLINK NAS TRANSPORT message when receiving the first DOWNLINK NAS TRANSPORT message sent by an MME; determining a target acquisition mode of the wireless capability information of the mobile terminal according to the working mode; and acquiring wireless capability information of the mobile terminal according to the target acquisition mode. The problem that the wireless resource utilization rate is low due to the inability to obtain the wireless capability of the mobile terminal in real time is solved, and the beneficial effect of improving the utilization of the wireless resource is obtained.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for acquiring wireless capabilities. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) communication network, mobile terminals have CP CIOT (Control Plane Cellular Internet of Things, control plane cellular Internet of Things) working mode and UP CIOT (User Plane Cellular Internet of Things, user plane cellular Internet of Things Networking) two working modes. The biggest difference between the two modes is that when the link between the mobile terminal and the core network changes from the idle state to the connected state, in the UP CIOT working mode, the MME (Mobility Management Entity, mobility management entity) will report to the E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Unified Terrestrial Radio Access Network) sends an INITIAL CONTEXT SETUP REQUEST message, and carries UE Ra...
