Problems solved by technology

[0013] However, the allocation of resources required by existing ProSe services is controlled by the eNB, and the MME does not know about it
The MME may trigger the release of the UE connection without knowing it.
Once the connection of the UE is released, the resources required for the ProSe service allocated to the UE will be released, resulting in the interruption of the ProSe service of the UE, resulting in poor user experience

Embodiment 1

[0137] Figure 6 It is a schematic diagram of Embodiment 1 of a method for supporting UE connection control in the present invention. The method includes the following steps:

[0138] Step 601: UE initiates a ProSe resource allocation request to eNB. The UE may request resources or transmission resources of the ProSe direct discovery service or the ProSe direct communication service.

[0139] Step 602: the eNB allocates resources required by the ProSe service for the UE, and the eNB returns a ProSe resource allocation response to the UE. The resources required by the ProSe service may be the resources required by the ProSe service exclusively used by the UE, or the resources required by the ProSe service exclusively used by the UE for transmitting signals. For example, the dedicated resources of the ProSe direct discovery service (Type2B), and the dedicated resources of the ProSe direct communication service (mode1).

[0140] Step 603: the eNB sends a first indication to t...

Embodiment 2

[0142] Figure 7 It is a schematic diagram of Embodiment 2 of the method for supporting UE connection control in the present invention. The method includes the following steps:

[0143] Steps 701 to 703 are consistent with steps 601 to 603 and will not be repeated here.

[0144] Step 704: the MME sends a first indication to the SGW. The MME may send the indication to the SGW by modifying the bearer request message or a new message.

[0145] Step 705: the SGW sends a first indication to the PGW. The SGW may send the indication to the PGW by modifying the bearer request message or a new message. After receiving the first indication, the PGW saves it in the UE context. When the PGW decides to release the UE's PDN connection, it needs to further consider the UE's ongoing ProSe service before deciding whether to release the UE's connection or continue to maintain the UE's connection.

Embodiment 3

[0147] Figure 8 It is a schematic diagram of Embodiment 3 of the method for supporting UE connection control in the present invention. The UE is in an idle state, and the UE requests ProSe resources from the network. The method includes the following steps:

[0148] Step 801: the RRC connection between UE and eNB is established. The UE may request to allocate resources required for ProSe services through an RRC establishment request or a new RRC message. The resources required by the ProSe service may be the resources required by the ProSe service exclusively used by the UE, or the resources required by the ProSe service exclusively used by the UE for transmitting signals. The UE may request resources or transmission resources of the ProSe direct discovery service or the ProSe direct communication service.

[0149] Step 802: The UE initiates an attach request, a TAU request or a service request to the MME, requesting to establish a connection.

[0150] Step 803: MME send...

Abstract

The invention provides methods supporting UE connection control and devices. UE or an eNB indicates a device in a core network that the UE is conducting a ProSe (proximity-based service), and the device in the core network further decides whether or not to release connection of the UE according to the ProSe being conducted by the UE when deciding to release UE connection. By implementing the application, connection control between the UE and the network is supported, and the situation in which the ProSe resources of the UE are released and the ProSe of the UE is interrupted due to wrong release of UE connection is avoided.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and equipment for supporting UE connection control. Background technique [0002] Modern mobile communication tends to provide diversified services to users more and more. At present, the public safety department of the United States has adopted the LTE network as the basic communication network of its public safety communication service. Proximity-based service (proximity-based service, ProSe for short) between UEs is an important part of public safety communication requirements, including proximity discovery between UEs and proximity communication between UEs. Proximity discovery between UEs is the basis of direct communication between UEs. It can sense whether there is a friend user nearby, and prompt the user to perform the next operation. In the field of public security, it is helpful for members of the public security executive department to conduct ta...
