Description

Method and device for called access

Technical field

The present application relates to the field of communications technologies, for example, to a method and apparatus for called access.

Background technique

The 2G and 3G mobile networks are divided into a circuit domain and a packet domain. The circuit domain is responsible for voice and short message communication, and the packet domain is responsible for data access. However, for LTE (Long Term Evolution) technology, that is, 4G, these two domains begin to merge. The circuit domain service will be added to the packet domain for transmission, eliminating the circuit domain.

4G network bears voice services using LTE telephony (VoLTE), which is Voice over LTE. It is an IP data transmission technology that does not require 2G or 3G networks. All services are carried on 4G networks, enabling data and voice services to be on the same network. Unification underneath. In other words, the 4G network not only provides high-speed data services, but also provides high-quality audio and video calls, which requires VoLTE technology.

However, due to the time required for network construction and improvement, when the 4G network is deployed, it is often limited by technology and network coverage. VoLTE is not used to take over voice services. Instead, CSFB (Circuit Switch Fallback) is adopted. The 4G mobile phone under the LTE network falls back to the 2G/3G network during the call, and the circuit domain attribute is still retained in order to support the CSFB scheme paging.

Although the called paging distinguishes between the circuit domain and the packet domain, the access reason of the UE (User Equipment, User Equipment) access procedure request message is not distinguished, and the evolved Node B (eNodeB) cannot be distinguished according to the service priority. When the number of access users is large, users cannot access users according to service priorities. At the same time, 4G networks are popular, operators start commercial VoLTE services, and voice services begin to be carried to the packet domain. There are multiple types of packet domain services. Different services have different access delay requirements. The short message service and the VoLTE service have different access delay requirements. If the packet domain paging is not subdivided, the eNodeB cannot distinguish between When a user accesses congestion, it cannot be processed according to the service priority.

The access delay is very important for the user experience. The reason for the reason that the VoLTE calling UE access request has been added is differentiated, but there is no subdivision for the called party, which will affect the live network user experience.

Third embodiment

In order to understand the called access method described in the first embodiment and the second embodiment of the present disclosure, an example will be described below.

In the embodiment of the disclosure, the paging message (the paging message sent by the MME to the base station) in the 3GPP TS 36.413 protocol is extended, and an optional cell (named as CN PS Domain) is added to the message body, and is configured to indicate that the packet domain is called. business type.

The UEa, the UEb, and the UEc receive the paging message, and initiate the RRC access request process to request the access network. The establishment cause in the RRC connection request (Connection Request) message carries the relevant service access reason. The UE1 is the access reason mt-CsCall is called, the UE2, and the UE3 access are mt-VoiceCall called, and the UE4~UE30 access is mt-PsCall called.

The eNodeB receives the RRC Connection Request and exceeds the admission capability due to the number of UEs to be accessed. Therefore, the eNodeB discards the access according to the access reason. The priority access service has higher real-time requirements, UEa, UEb, and UEc, and denies access to UEd to UEz. .

Among them, when there are other services that are simultaneously connected to the base station, such as Emergency (business emergency call) service, High Priority Access (high priority access) service, mo-VoiceCall (VoLTE caller) service, and mo-Signalling (signaling) The calling party can establish the service only in the following priority order, such as the establishment of the signaling interaction, such as the location area update service, the Delay Tolerant Access service, and the mo-data service. Access: Emergency (business emergency call) service, High Priority Access (high priority access) service, mt-CsCall (CSFB called) service, mt-VoiceCall (VoLTE called) service, mo-VoiceCall (VoLTE caller) ) service, mt-PsCall (general packet domain data called) service, mo-Signalling (signaling caller, only signaling interaction establishment, such as location area update) service, Delay TolerantAccess (allow delay access) service, mo -Data (general data caller) service, etc. It should be understood that the foregoing priority order may be adjusted according to actual needs, and the embodiments of the present disclosure do not limit the times.

In summary, the technical solution provided by the embodiment of the present disclosure distinguishes the called service, so that the called terminal can determine the called access reason according to the called service type, so that the base station can determine in the access process.
