Problems solved by technology

In the prior art, when the eNB allocates uplink resources to the UE, it does not consider the requirements of different services. For example, the eNB does not allocate PUCCH resources for the UE according to the needs or releases the PUCCH resources after allocation. At this time, if the UE pe

Embodiment Construction

[0025] Embodiment 1 of the present invention provides an emergency call service method, including the following steps:

[0026] Step 101, reserving resources for applying for uplink service resources for user equipment UEs performing emergency call EMC services;

[0027] It also includes before, after receiving the radio resource control connection request RRC CONNECTIONREQUEST sent by the UE, allocating resources for applying for uplink service resources to the UE, establishing RRC CONNECTION SETUP through the radio resource control connection, and using the allocated resources for applying for uplink service resources Notify the UE; or, after the radio resource control RRC connection is established, according to the parameters in the S1 interface message and / or the stored connection establishment reason, it is determined that an emergency call service needs to be established, and the UE is allocated resources for applying for uplink service resources , notifying the UE of th...

Abstract

The invention discloses a method, an evolution base station and a system for an emergency call service, which solve the probably-occurred problem of resource scarcity in an emergency call. The method comprises the following steps of: reserving a resource, used for applying for an uplink service resource, for user equipment (UE) which performs the emergency call (EMC) service; receiving an uplink service resource request sent by the UE through the reserved resource used for applying for the uplink service resource, and allocating a physical layer uplink shared channel (PUSCH) to the UE; and receiving uplink data sent by the UE through the PUSCH.

Description

technical field [0001] The invention relates to the communication field, in particular to emergency call service technology. Background technique [0002] At present, research work on LTE (Long Term Evolved, Long Term Evolved Network) / SAE (System Architecture Evolved, System Architecture Evolved Network) is in progress. The purpose of LTE is to provide a low-cost network capable of reduced latency, increased user data rate, improved system capacity and coverage. [0003] In the LTE / SAE network, eNB (eNodeB, evolved base station) can allocate a dedicated PUCCH (Physical Uplink Control Channel, physical layer uplink control channel) to UE (User Equipment, user equipment) in RRC_CONNECTED state (RRC_CONNECTED) as needed resources, when the UE needs to send uplink data but there is no corresponding uplink PUSCH (Physical Uplink Share Channel, physical layer uplink shared channel) resources, the UE can use the PUCCH to send SR (Scheduling Request, scheduling request). However, ...
